A perspective from Lighting Recipe Studio on platform IP, strategic positioning, and the future of the lighting industry

If the future of lighting remains limited to “selling hardware,” it will be difficult for the industry to command higher value. But if light can be turned into a platform, into algorithms, into data, and into a verifiable human-centric system, then it is no longer just a product. It becomes foundational infrastructure for the next generation of space, health, and environmental technologies.

That is the core value behind Lighting Recipe Studio’s latest patent progress and broader IP strategy.

Introduction: Many companies think patents are about protecting products. In reality, what determines future positioning is higher-order patent strategy and system architecture.

Many business leaders still view patents primarily as a defensive tool. Patents make products safer to commercialize. They strengthen marketing claims. They make copying more difficult.

All of that is true. But if that is the full extent of how a company understands patents, then it is significantly underestimating their strategic importance.

In high-value industries, what determines future positioning is no longer simply whether a company owns a few isolated inventions. What matters far more is whether it has built a coherent higher-order patent structure — one that is aligned with the future direction of the industry, expandable over time, and capable of covering products, systems, and platforms downstream.

Put simply:

A point patent protects a function. A higher-order patent strategy helps define an entire competitive domain. A narrow patent may protect a component, a module, or a localized technical improvement.

But a top-level architectural patent strategy competes for something much larger:

• product definition power
• system integration power
• platform extension power
• and, ultimately, influence over how the industry evolves

This is why Lighting Recipe Studio has never focused only on making a lamp brighter or more efficient.

Our long-term effort has been directed toward something much more fundamental: building the underlying technological architecture for the next generation of lighting.

After our latest patent grants, one thing has become even clearer: what will be scarce in the future is not lamps — but platform-level IP

Today, the lighting industry still appears to compete largely on products, parameters, pricing, and efficiency. But those are still mostly hardware-era dimensions of competition.

What will determine the next phase of value creation is something else entirely: who can establish a foundational technology platform built around

• human needs
• spatial scenarios
• sensing and control
• algorithmic and data-driven intelligence
• and verifiable outcomes

This is the real reason behind our continued patent development.

At Lighting Recipe Studio, we are not only interested in how to make lighting products. We are interested in how to turn light into a system capability — something that can be understood, modeled, computed, orchestrated, adapted, and verified.

With several key patent grants added this year, the picture is becoming increasingly clear: What we are building is not a collection of disconnected feature patents.

It is a structured portfolio of higher-order patents centered around how the lighting industry itself is likely to evolve. The value of such a portfolio does not lie in protecting a single clever idea. Its value lies in becoming an entry point for future products, systems, platforms, and strategic collaboration.

We are not building protection around a product feature. We are building the technological architecture for next-generation lighting.

Many patents fail to create real industrial value not because the technology is weak, but because the scope is too narrow. Such patents may be defensible, but they are difficult to scale. They may be grantable, but they do not necessarily shape the market.

Lighting Recipe Studio has taken a different approach. Rather than adding isolated technical patches around individual functions, we have been structuring IP around a more fundamental question: How will lighting evolve in the next decade?

That means protecting not just one product concept, but building what could be described as a human-centric lighting technology stack.

This is also why our portfolio is particularly relevant for:

• technology licensing
• joint development
• platform integration
• industrial collaboration
• capital partnerships
• strategic transactions and asset-level cooperation

Its value is not limited to protecting a product. Its value lies in defining the boundaries, pathways, and interfaces for future categories of products and systems.

1. Core human-centric lighting platform: from device control to system definition

This is the structural backbone of the portfolio and one of the clearest examples of higher-order patent positioning. It is not about simple dimming or tunable white control.

It is about enabling lighting systems to function at a higher level, including:

• control logic linked to space and scenario
• coordination mechanisms for multi-user environments
• editable and deployable spectral and scene orchestration
• shared scene logic and platform-based invocation
• dynamic feedback through ambient-light monitoring

The deeper significance of this type of IP is that it moves lighting from device-layer competition to system-layer competition.

The companies that master this layer are more likely to gain:

• product definition power
• system integration leverage
• platform interoperability advantage
• and scenario extension capability

That is what makes higher-order patents so important. They do not merely protect a part. They protect the architectural method, the system pathway, and the entry point.

For the industry, this kind of IP is valuable because it can be integrated not only into luminaires, but also into control systems, sensing modules, IoT platforms, smart-building frameworks, and even health-oriented space solutions.

2. Emotion-adaptive and personalized lighting: from standardized output to state-responsive systems

Much of the industry still talks about healthy lighting in relatively basic terms — correlated color temperature shifts, time-based schedules, and circadian timing. But the future will not be defined by whether a system can switch between warm and cool white.

It will be defined by whether lighting can respond intelligently to the condition of the person. Stress, emotion, preference, behavioral pattern, and daily rhythm all shape how light should intervene.

That is why part of Lighting Recipe Studio’s IP strategy has focused on a higher-order direction: transforming lighting from a fixed-output system into an adaptive, person-responsive system.

This matters because it creates bridges between lighting and adjacent sectors such as:

• health technology
• digital wellness
• consumer electronics
• intelligent environments
• automotive interiors
• and even digital therapeutics

The most valuable lighting systems of the future will not simply deliver illumination. They will interpret human state, match intended purpose, adjust the light environment dynamically, and improve over time. Whoever establishes this architecture early will have a strong position in future cross-industry convergence.

3. Precision and clinical lighting: from general illumination to high-value professional systems

Once lighting begins to connect more directly with measurable human outcomes, it stops being merely a building component and starts becoming part of a professional system.

This is another strategic direction that Lighting Recipe Studio takes seriously: moving light from general-purpose use into higher-value, higher-threshold application domains.

This includes areas such as:

• infant and child lighting regulation systems
• intervention-oriented lighting methods
• precision lighting capabilities for healthcare, care environments, sleep, and recovery settings

The significance here is substantial. As soon as light becomes more clearly linked to physiological, behavioral, or health outcomes, its value position changes. It is no longer just part of equipment procurement.

It becomes closer to:

• a professional solution
• an outcome-oriented system
• a high-value entry technology
• a collaborative platform for health and care ecosystems

This is not the kind of value that one or two product launches can fully absorb. It is more likely to expand through joint development, clinical collaboration, and sector-specific strategic partnerships.

4. Multispectral circadian scenarios and databases: from emitting light to owning the content and data layers

A great deal of what is marketed today as circadian lighting still amounts to little more than timed schedules and CCT transitions.

But if lighting is to genuinely respond to rhythm, stress, purpose, and state, then a much deeper system layer is required, including:

• multispectral circadian scenarios
• methods for building scenario databases
• relationships between lighting conditions and indicators such as stress or psychological state
• scenario generation, recall, and ongoing optimization

This changes the nature of competition. Future competition in lighting may not only take place in luminaires.

It may increasingly take place in:

• who owns the scenario layer
• who owns the database layer
• who owns the algorithmic logic
• who owns the optimization engine

This is exactly why higher-order patent positioning matters. Once lighting expands from hardware into content and data, business models change. Valuation models change. The role of a company within the industry changes.

Selling a luminaire is one thing. Owning the content layer and the data layer is something far more strategic. It enables the shift from one-time product sales toward service, platform collaboration, ongoing optimization, and long-term value capture.

5. Sensing, flicker, and calibration extensions: making the platform real, deployable, and verifiable

No platform can become mainstream if it relies only on idealized settings.

A true platform must be able to:

• sense the field condition
• correct deviations
• maintain consistency
• support verification

That is why Lighting Recipe Studio has also continued to build IP around areas that may appear secondary, but are in fact essential to industrialization, including:

• flicker-related monitoring and control
• LED spectral auto-calibration
• integration with modules, drivers, measurement systems, and quality workflows

These elements matter because they determine whether a platform can move from concept to deployment. Many ambitious solutions remain trapped at the demonstration stage not because the vision is weak, but because the supporting architecture for calibration and verification is missing.

The value of higher-order patents is not only that they describe a future vision. It is that they help create the technical foundation required to make that vision work in the real world.

A real platform is not one that only tells a compelling story. It is one that can operate in complex environments, remain consistent across different systems, and support validation across real applications.

What Lighting Recipe Studio is really trying to solve is not just how to illuminate space — but how to create a new technical language for the industry.

For too long, the lighting industry has concentrated most of its effort on equipment, metrics, and efficiency. These matter. But they are no longer enough. If the industry continues to understand light only through a hardware vocabulary, it will struggle to enter higher-value domains.

Today, more and more companies are talking about health, comfort, rhythm, experience, and scenario. But in many cases, these remain marketing narratives rather than fully structured technical systems.

This is precisely the reason behind our continuing IP work: to ensure that light is not merely switched on, but understood, modeled, orchestrated, adapted, and verified.

Once that technical language is established, the impact extends far beyond a single product generation. It begins to shape the infrastructure of the industry’s next upgrade cycle.

Whoever masters that language first will be better positioned to become a central node in future collaboration. Whoever builds that architecture first is more likely to move from participating in competition to defining it.

Why this type of top-level patent strategy matters for the future of the industry

Because every maturing industry eventually shifts from “who can make it” to “who can define it.”

In the early stage of an industry, competition tends to revolve around:

• 效率
• cost
• speed
• channel access

But as industries become more platformized, systemized, and intelligent, the key questions change:

• Who defines the system architecture?
• Who controls the critical interfaces?
• Who sets the collaboration framework?
• Who owns the most extensible technical boundary?
• Who can transform isolated capabilities into platform capabilities?

A higher-order patent strategy is fundamentally about competing for those rights. Its importance lies not only in determining whether a company can launch a product. It helps determine how the industry itself will be organized, integrated, and commercialized. In that sense, patents are no longer just about preventing imitation.

They are increasingly about:

• future market access barriers
• negotiating leverage in partnership
• the foundation for platform integration
• sources of strategic premium
• and long-term influence over industry positioning

Business leaders who understand technology strategy do not see patents merely as R&D outputs. They see them as instruments of future positioning.

For business leaders, the importance of patent strategy is not just protection — it is positioning.

If a company still treats patents only as an auxiliary task of the R&D department, it may remain a participant in future competition, but it is less likely to lead it. Because the more valuable companies of the future will not only possess manufacturing capability.

They will also possess:

• architectural capability
• platform integration capability
• system extension capability
• industrial collaboration capability
• and IP control capability

The importance of a patent strategy does not lie in how many patents are filed. It lies in whether the portfolio has a clear top-level logic.

Can it cover the direction of industry evolution? Can it become difficult to work around? Can it become an interface that future partners must engage with?

That is what strategic IP really means. And that is the dimension along which Lighting Recipe Studio has been positioning itself.

The earlier management teams understand this, the greater their ability to secure a strong role in future industry integration and technology transition. The later they understand it, the more likely they are to become merely an execution layer within someone else’s architecture.

Closing reflection: while much of the industry is still competing through products, the real competition is already moving toward foundational architecture

The lighting industry will, of course, continue to compete through products. But product competition alone will not define the next stage.

What will become truly scarce is not a lamp that is slightly brighter, cheaper, or more efficient. What will become scarce is the capability to turn light into a platform, into a system, into algorithms, into data, and into verifiable outcomes.

That is why Lighting Recipe Studio has never regarded patents simply as certificates of invention.

We see them as a way to participate in defining the future rules of the industry — through higher-order patents and foundational architecture. The most valuable patents are not the ones framed on a wall. They are the ones that enter real systems, real partnerships, and real industrial structures — and ultimately help shape future competitive dynamics.

Seen from this perspective, patent strategy is not merely a legal matter or an R&D matter. It is a strategic matter. A future-position matter. And, increasingly, a matter of industrial influence.

We are not interested in displaying patents. We are interested in enabling collaboration and industry-scale value creation.

For Lighting Recipe Studio, patents are not the end point. They are the starting point of industrial collaboration.

The questions we care about are straightforward: Can these technologies enter real environments? Can they create differentiated advantage for partners? Can they become the basis for product, system, and platform collaboration? Can they help turn “good light” from a concept into a scalable, verifiable industrial capability?

If your organization is working in areas such as:

• human-centric and healthy lighting
• smart lighting control
• multispectral circadian lighting
• sensing and closed-loop control
• WELL, healthy buildings, sleep, or medical lighting
• technology licensing
• joint development
• platform collaboration
• strategic integration
• capital or asset-level cooperation

we would be glad to connect. We believe the scarcest asset in the next phase of the lighting industry will not be a standalone product. It will be platform-level IP capable of defining future system architecture.

And that is exactly why Lighting Recipe Studio continues to invest in higher-order patent strategy.

最後一句

Lighting is no longer just about illumination. It is becoming infrastructure for human vitality.

前言

这是我于 2026 年 3 月 26 日参加 2026 IWBI 全球顾问启动会议后的一点心得。

先说明一点：这篇文章不是对会议内容的逐条复述，也不是对仍处于公开预览与 public comment 阶段文本的官方解读。我更想分享的是，在目前 One WELL 已进入公开阶段的背景下，它所释放出来的一个非常清楚的信号：

One WELL，绝不只是一次技术性的标准整合。

它更像是 IWBI 正试图把 WELL，从一套健康建筑认证工具，进一步推向一套更统一、更易实施、更可持续迭代的平台型标准体系。

这也是为什么，我认为它对产业、对 IWBI 本身，都有比很多人想象中更深的意义。

一、如果不了解 WELL 为什么会出现，就很难真正看懂 One WELL

过去十多年，建筑行业最重要的一股趋势之一，是绿色建筑的快速发展。无论是节能、低碳、材料、用水，还是环境影响评估，各类绿色建筑体系都极大地推动了产业进步。

但行业也慢慢意识到一个问题： 建筑变得更绿色了，并不自动等于更适合人。

节能，不等于舒适；低碳，不等于健康；系统效率提升，也不等于人的状态真的更好。

于是， 建筑行业开始从“建筑是否高效”，进一步追问“建筑是否真正服务于人的健康与福祉”。

WELL 的出现，本质上就代表了这样一种视角转向：建筑不应只被理解为能源系统，也必须被理解为影响人身心状态的环境系统。

所以 WELL 最重要的地方，不只是多了一套条款， 而是它把“人”重新拉回到建筑评价的中心。

二、One WELL 不是简单做一个新版本

而是在回应 WELL 成功发展后带来的复杂性。’s Own Success

随着 WELL 不断扩展，它的适用边界越来越广，影响力也越来越大。但体系一旦持续成长，复杂性也会随之上升。

从目前公开释放出的方向来看，One WELL 所回应的，并不只是“要不要更新标准”，而是更现实的几个实施问题：标准内容越来越丰富，但理解门槛也随之提高；多地点、多项目、多版本并行时，管理成本会上升；同类策略在不同场景中的理解与实施，容易出现偏差；而标准更新本身，也需要更可追踪、更可比较的机制。

所以，One WELL 的出现，不只是为了“做一个新版 WELL”，而更像是在解决 WELL 从成熟走向规模化过程中，必然会遇到的系统摩擦。

换句话说： One WELL 不是从包装出发， 而是从复杂性治理出发。

三、One WELL 的第一层意义，是去碎片化。

很多人第一眼看 One WELL，会觉得它就是把不同项目类型、不同路径、不同应用方式收拢到一起。 这当然没错。但它更深一层的意义，不只是“更方便”，而是去碎片化。

过去产业里并不是没人谈健康。相反，大家都在谈。开发商谈资产价值，设计师谈空间体验，工程端谈系统性能，品牌商谈产品参数，顾问谈条文与路径，而最终使用者在意的，却是睡眠、专注、舒适、恢复与长期状态。

问题不在于谁错。问题在于：这些语言常常彼此接不上。于是市场上就会出现一个很常见的现象： 大家都在说健康， 但健康始终没有真正变成一套统一的行动逻辑。

而 One WELL 的重要意义，就是试图把这些分散的表达，重新拉回一个更统一的结构中。

所以它不只是整合文本，更是在整合语言。

四、One WELL 不是只在统一名称

而是在统一逻辑、统一呈现、统一理解方式。

从目前公开阶段能看到的方向中，One WELL 很强调几个关键词： Harmonized, Clarified, Evergreen, and Smarter.

如果用更容易理解的话来说，大致就是四件事：

首先， 更统一。也就是尽可能减少不同路径、不同模块之间那种“名字很像、逻辑不同”的摩擦。

其次， 更清晰。不是单纯增加内容，而是让策略写法、适用性表达、阅读方式更容易理解与实施。

再來， 更持续更新。不是每隔几年做一次剧烈重构，而是通过持续增强、逐步优化的方式演进。

第四， 更像平台。不仅是发布标准，还要让数字界面、比较机制、变更记录、进度追踪等功能，真正支持使用者在实施过程中管理复杂性。

这说明 One WELL 的目标，不只是让专业人士更方便看标准，而是让 WELL 更适合被团队、组织和多项目体系持续使用。

五、One WELL 更深的意义，不是整合标准。

而是让 WELL 更像一个平台。

这是我认为最值得产业重视的地方。过去很多人理解标准，还停留在很传统的想象里：标准，就是一本书；一套条文；一张 checklist；一套认证要求。

但真正有影响力的标准，从来不只是文件。它同时也是一种组织市场的方式。

从目前 One WELL 公开预览中能看到的方向看，IWBI 显然不只是想让 WELL 更完整，它还想让 WELL 更具备这些特征：

• 更容易被比较与追踪；
• 更容易被组织层面管理；
• 更容易支持多地点、多项目组合；
• 更容易随着更新持续演进；
• 更容易让使用者看到进展、变化与累积成果。

当这些特征逐渐强化时，WELL 的角色就不再只是认证体系，而越来越像一个平台型系统。

所以我才会说： One WELL 的意义，不只是把 WELL“合成一个版本”， 而是在把 WELL 重构成一个更统一、更动态、更可管理的平台型标准体系。

六、这会直接改变产业的价值排序。

当健康开始通过更统一的语言、更一致的结构、更持续的更新机制来表达时，产业的价值逻辑也会跟着变化。

过去很多企业竞争的是：谁的产品参数更漂亮；谁的设计更好看；谁更懂认证路径；谁更会讲健康概念。

但未来，真正重要的问题会越来越变成： 你能不能把“健康”这件事，更稳定、更清楚、更可验证地交付出来。

这意味着市场会逐步从：卖产品，走向卖结果；做一次性交付，走向持续追踪；讲概念，走向讲实施能力；讲设计意图，走向讲组织层面的健康策略与绩效。

对企业来说，这不是修辞变化。这是竞争逻辑的变化。

七、对照明行业来说，这个信号尤其直接。

为什么我特别强调照明行业？因为照明行业过去太容易把复杂问题说简单。

照度、色温、显指、节能、控制、场景，这些当然都重要。但这些从来不自动等于“健康光”。

真正与人有关的光，一定同时涉及：人是谁；空间是什么；在什么时间；做什么活动；暴露多久； 目标是什么；最后结果如何验证。

而在 One WELL 这样更统一、更强调实施与持续优化的逻辑下，光不会再只是某个 concept 下的一组条文，而会越来越被放到更清楚的战略目标、组织逻辑与结果导向中去理解。

这对照明行业是一个很明确的提醒：未来竞争，不只是讲灯具，也不只是讲参数，而是要开始讲：

你的光，如何在一个更完整的人、空间、时间与策略框架中，真正创造可衡量的价值。

这对真正有系统能力的企业，是机会。但对只停留在产品包装与概念营销层面的企业，会越来越有压力。

八、One WELL 还释放出一个重要信号：标准正在从“版本制”走向“持续增强制”。 From Version-Based Thinking to Continuous Enhancement

这也是这次公开阶段很值得注意的一点。 One WELL 不是在传递「某一天上线一个最终版本，然后多年不动」的感觉，而更像是在建立一种持续增强、渐进演进的逻辑。

这种逻辑意味着：标准不只是发布，还要持续吸收回馈；不只是定稿，还要持续优化；不只是审查专案，还要帮助组织更有效地管理进展。

也正因如此，One WELL 的公开征询阶段才特别重要。 它不是一个形式性的流程，而是在为后续的平台化演进建立市场输入机制。所以对行业来说，现在最值得做的，不是急着下结论，而是认真看方向、提意见、参与讨论。

九、因此，现阶段讨论 One WELL，最需要的是分寸感

我觉得这点很重要。因为 One WELL 目前处于公开预览与 public comment 阶段。这意味着行业当然可以讨论它的方向、意义与潜在影响，但也应该尊重这个阶段的边界：

可以谈公开资讯释放出来的制度逻辑；可以谈对产业与企业意味着什么；可以提出专业回馈与建议；但不宜把尚未最终确定的内容写成既定事实，更不宜把内部交流语境，直接当作对外定稿表达。

这既是专业态度，也是对 IWBI 机制本身的尊重。

十、结语：One WELL，不只是把 WELL 做大

而是在把「健康」变成一种更可部署的秩序 “Health” Into a More Deployable Order

所以回到最初的问题： One WELL 对产业意味着什么？

它意味着，健康建筑产业开始从碎片化走向系统化，从多方各说各话，走向更统一的语言与逻辑， 从静态标准，走向更动态的平台型体系。

One WELL 对 IWBI 又意味着什么？

它意味着，IWBI 正在从标准发布者，进一步走向平台组织者；从单纯认证体系的拥有者，走向健康建筑生态语言和实施逻辑的塑造者。

而对照明行业来说，这个信号尤其明确：未来的竞争，不再只是看谁能把空间照亮；而是看谁能真正证明—— 光，如何在一个更完整的人本框架里，改善人的状态。

这，才是 One WELL 真正值得重视的地方。

文末说明

本文基于作者参加 2026 IWBI 全球顾问启动会议后的个人观察，并结合目前已进入公开预览 / public comment 阶段的 One WELL 相关公开资讯所作之思考。本文不构成对 IWBI 最终标准文本的官方解读，具体内容仍应以 IWBI 后续正式发布版本为准。

当我们谈病态建筑，为什么总是忘了「光」？

人类现代建筑史，在某种程度上，也是一部人类驯服黑夜的历史。

从爱迪生将白炽灯推向量产开始，光第一次真正脱离了火焰、脱离了日落，成为可被控制、可被部署、可被复制的基础设施。

从那一刻起，建筑不再只是遮风避雨的壳体，而开始拥有延展时间、塑造行为、重组生活节奏的能力。

光，让空间从白天的附属品，变成二十四小时运转的人类场域。

而后，建筑大师柯比意说，光是空间的第四维度。
这句话之所以伟大，不只是因为它浪漫，而是因为它准确。

因为真正塑造空间感知的，从来不只是墙、地、顶三个维度，还有光如何进入、停留、转折、消失。

没有光，空间只是体积。
有了光，空间才有了层次、方向、情绪、秩序，甚至灵魂。

所以很长一段时间里，建筑与照明共同追求的，是一件本来很了不起的事： 不只是照亮空间，而是照靓空间。

光让建筑更可见，让材料更有质感，让秩序更清晰，让城市的夜晚有了表情。 光曾经是文明的延伸，也是建筑最有力量、最有温度的语言之一。

但今天，我们似乎走到了一个值得警惕的岔路口。

当节能成为唯一正确，建筑开始慢慢忘记自己是为谁存在

近十多年来，节能成了建筑领域几乎不可挑战的政治正确。

节能当然重要，减碳也当然必要。
问题不在于节能本身，而在于我们是否在不知不觉中，把手段当成了目的。

因此

• 于是，照明功率密度一再被压缩。
• 于是，白天的室内被设计得越来越暗，仿佛只要满足最低标准，建筑就算完成了责任。
• 于是，夜晚的城市却越来越亮，招牌、立面、景观、屏幕彼此竞逐，让黑夜失去了作为黑夜的权利。

这是一个荒谬但真实的时代切面：

• 我们在白天，给人不够的光；
• 在夜晚，却给人过量的光

白天本该提供清晰、充足、能支持觉醒与专注的环境；
夜晚本该收敛、降躁、保留黑暗，让人的生理节律能够回到平衡。

但今天大量建筑恰好相反。

• 办公室里，人们在白天精神涣散、眼睛疲劳、情绪低沉；
• 酒店里，住客明明想休息，却被错误的色温、眩光与光泄漏打扰；
• 医院里，病人和医护长时间暴露在不对时、不对量、不对方向的光环境里；
• 住宅里，孩子白天不见天日，晚上却被屏幕和高刺激照明包围。

这不是技术不够。
恰恰相反，这是因为我们太久以来，把光只当成了:

• 设备问题
• 能耗问题
• 装饰问题

却没有把它当成人的问题、时间的问题、健康的问题。

---

病态建筑，不该只谈空气，却对光失语。

今天当我们谈到 Sick Building Syndrome（病态建筑症候群），大家很自然会想到:

• 空气质量
• VOC
• 通风不足
• 湿度控制
• 霉菌
• 过滤系统

这些都很重要。但奇怪的是，光常常被边缘化。 仿佛只要空气好了，建筑就健康了。

事实上，一栋真正让人疲惫、失眠、焦躁、头痛、效率低落、情绪失衡的建筑，往往不只是空气出了问题。它同时也可能存在：

• 不足或错误时段的光暴露
• 不合理的眩光与高亮对比
• 白天垂直照度不足
• 夜晚刺激过高
• 热舒适失衡
• 噪音持续干扰
• 空间节奏与人的活动模式错位

也就是说，病态建筑从来不是单因子的结果，而是多环境因子共同失调的综合症。

如果我们今天承认空气会让人生病，为什么不承认光也会？
如果我们承认噪音会造成压力，为什么不承认错误的光会破坏睡眠与节律？
如果我们承认热舒适影响生理负荷，为什么不承认光同样在调节人的警觉、情绪、激素与行为？

建筑若以服务人为目的，就不能只在一个指标上表现优秀，却在另一个更基础的维度上持续失分。

---

我们需要的，不是更多灯，而是重新理解光的角色。

问题的根本，不在于要不要多装几盏灯，也不在于把照度表上的数字再拉高一点。

真正需要被重建的，是我们对光的理解框架。

因为光从来不是孤立存在的。它总是与以下几件事交织在一起：

• 人 — 这是谁？年龄、作息、敏感度、健康状态、任务需求是否不同？
• 空间 — 这是哪？办公、学习、医疗、住宅、交通、商业、酒店，其目的完全不同。
• 时间 — 是清晨、白天、傍晚、夜间，还是跨时区与轮班情境？
• 活动 — 人在这里是专注、休息、社交、疗养、康复、转换，还是沉思？

所以光的设计，不应再停留在:

• “够不够亮”
• “好不好看”
• “省不省电”三个问题。

而应该进一步问：

这个空间，在这个时间，为这群人，支持的是什么活动？
它提供的光，究竟是在帮助人，还是在消耗人？

这才是未来建筑与照明真正应该回答的命题。

---

建筑的目的，从来不是节能本身，而是用更好的方式服务人。

这句话可能需要被重新说一次：建筑的目的，从来不是节能。

节能很重要，但节能不是建筑存在的本体目的。

建筑的本质，是提供：

• 庇护
• 秩序
• 效率
• 尊严
• 健康
• 交流
• 康复
• 休息
• 与生活的可能

如果一栋建筑极度节能，却让人昏沉、焦躁、失眠、低效，那它在能耗账本上也许是成功的， 但在人的尺度上，可能是失败的。

我们不能用节能的语言，把人的需求挤压成附属条件。
更不能让功率密度、最低标准、设备参数，取代了对人的真实关怀。

真正高水平的建筑，应该是能在能源、环境与人之间建立更高级的平衡。

不是回到粗放浪费的年代，而是进入一个更精准、更懂人、更讲究时间与场景的时代。

---

从“照明设计”走向“人的环境编排”

未来的建筑与光，也许需要的不再只是传统意义上的照明设计，而是一种更整体的环境编排能力。

这种能力要求我们同时思考：

• 白天如何让人真正清醒、专注、舒适
• 夜晚如何让空间降低刺激、保留休息的可能
• 光如何与自然采光、遮阳、材料反射、热环境、声环境协同
• 如何依照不同人群与活动节奏动态调整
• 如何用测量与验证，而不是只用想象与效果图判断成果

换句话说，未来不是

“灯具放哪里”而已，

而是

“这个环境如何在一天之中，真正服务人的身心节律与活动质量”

这里面，光不再只是装修完成前的最后一道工序。
它应该回到建筑一开始就被思考的位置。

不是附属，而是核心。
不是配角，而是基础设施。

---

是时候，把光重新放回建筑的中心。

我们这一代，或许正站在一个重要转折点上。

前一个时代，让我们学会如何有效地用光。
下一个时代，则要求我们学会如何正确地用光。

前一个时代，建筑追求的是可见。
下一个时代，建筑更应追求：

• 可感
• 可用
• 可恢复
• 可长久相处

当我们重新审视病态建筑，重新审视节能与健康之间的张力，也许最该被重问的，不是：

“还能再省多少电”

而是

• 这栋建筑，是否真正理解人？
• 它给人的光，是否符合人的时间、生理与活动需求？
• 它是否在白天支持生命，在夜晚尊重黑暗？

因为说到底

建筑不是为了证明自己有多节能而存在，
而是为了让人在其中活得更好。

而光，从来不只是把空间照亮。它更应该把人，重新带回建筑的中心。

摘要

当整个行业都在谈健康照明、节律照明与 human-centric lighting，LED 灯珠企业如果还只会在规格书里写光效、显指、色容差与价格，恐怕已经落后半个时代。

CIE S 026 带来的，不是多一个新名词，而是要求上游元器件企业重新建立一套能够描述“光如何作用于人”的规格语言。

真正关键的，不只是 melanopic，而是五类 α-opic DER 与 EDI 的完整框架；真正决定下一轮定价权的，也不是谁喊得最大声，而是谁先把这套能力写进 datasheet、做进 toolbox、接入应用链。

这两年，我越发强烈地感受到一件事： 很多 LED 企业，嘴上在谈健康照明，手上的规格书却还停留在上一个时代。

还在比什么？

• 比光效
• 比显指
• R9
• 比 SDCM
• 比价格

再进一步，开始谈 TM-30、低频闪、光品质。这些都对，但还不够。

因为如果今天整个行业都在说：光不只是让人看见，还会影响节律、警觉、情绪、睡眠、恢复，甚至长期健康；那么请问—— 为什么到了 LED 最上游的灯珠规格书，很多企业还在用一套几乎完全“看不见人”的语言？

这才是问题的核心。

不是 CIE S 026 重不重要，不是 melanopic、α-opic 难不难，而是：如果上游元器件企业自己都还没有能力，把“光如何作用于人”这件事，翻译成可交付、可运算、可比较、可设计的 datasheet 语言，那么整个健康光产业，大半都还只是口号。

这句话可能有点重，但我认为，现在是时候讲重一点了。

---

1. 很多企业误会了：CIE S 026 不是市场部多一个卖点。

现在不少企业开始了解 melanopic EDI，开始在简报里加上 α-opic，甚至有人已经想把这些词直接写进灯珠规格书。方向没错，但很多写法，一看就知道还没有真正理解 CIE S 026。

最大的误区是什么？就是把它当成另一个可以拿来包装高端的参数。这很危险。

因为 CIE S 026 不是一个新的 marketing badge，也不是一张能贴在包装盒上的认证标签。 它本质上是一套视网膜光受体加权的计量语言，是把“光对人”的描述，从模糊的概念，推向可以被精确计算的框架。

而一旦你真把它看成计量语言，你就会立刻意识到一件事：这不是在规格书上多加一个 melanopic 数字那么简单。

这是在逼着 LED 上游企业，重新回答一个问题：你卖的，到底只是一颗会发光的半导体元件，还是一个可被生理模型调用的光谱引擎？

这两者，差很多。

---

先把最根本的错误纠正：EDI 不只是 melanopic 一个。

我最近注意到，连不少业内人士都还停留在一个模糊认知里：以为 DER 是五类 α-opic 指标，但 EDI 好像主要就是 melanopic EDI。这个理解，实务上常见，但技术上并不完整。

如果回到 CIE S 026 的原始逻辑，事情其实很清楚：不只是 DER 有五类，EDI 本身也同样有五类。

也就是说，对应五类视网膜光感受器通道：

• S-cone-opic
• M-cone-opic
• L-cone-opic
• Rhodopic
• Melanopic

理论上都各自有：

• α-opic irradiance
• α-opic DER
• α-opic EDI

换句话说，EDI 不是一个值，而是一组值。

只是因为近年在昼夜节律、WELL、白天提神与夜晚抑制等应用沟通中，melanopic EDI 被最频繁单独拿出来用，久而久之，市场就误以为 EDI 差不多就是 melanopic EDI。

这个误会，看起来只是术语问题。但如果放到灯珠企业的规格书逻辑里，它会直接导致整个 datasheet 写偏。因为你一旦把 EDI 简化成单一 melanopic 指标，你其实已经默默把 CIE S 026 的完整五维框架，压缩成一条单线叙事。

而这，恰恰是我最不希望看到的事。

---

3. LED 行业最怕的，不是复杂；最怕的是“假装简单”。

我一直认为，LED 行业最大的能力之一，是把复杂问题工程化。当年 LED 替代传统照明，也不是因为 LED 本身不复杂。恰恰相反，是因为它太复杂。

它有电特性、有热特性、有光衰、有色漂、有 binning、有封装差异、有驱动耦合、有系统效率、 有寿命模型、有可靠性风险。

但后来整个行业之所以成熟，是因为大家逐步建立了一套共同语言，把这些复杂性，转化为客户能用、工程师能算、FAE 能解释、设计师能调用的规格与工具。

这才是 LED 产业真正了不起的地方。

所以今天如果 α-opic、EDI、DER 进入元器件体系，我的态度很明确：不要怕复杂。怕的是把原本五维的东西，偷懒写成一个单值，然后拿去做宣传。

那不是简化，那是降智。

因为一旦上游把多维光生理问题简化成一个“高 melanopic 就比较先进”的叙事，后面就一定会出现两种结果：

1. 市场部会过度包装。
2. 应用端会错误使用。

最后受伤的，不只是企业自己，还包括整个健康照明领域的公信力。

---

4. 对灯珠制造商来说，DER 跟 EDI 的角色根本不同。

这里我想讲得更直接一点：如果你是 LED 灯珠企业，真正应该优先写进主规格表的，是五类 α-opic DER；而 EDI，应作为条件化、归一化的结果量来呈现。

为什么？

因为 DER 更接近什么？更接近这颗 LED 光谱本身的属性。

只要 SPD 定了，DER 基本上就跟着定了。它是源级光谱特征。

那 EDI 呢？EDI 不是脱离条件的绝对常数。它是建立在某个 photopic illuminance 基础上的等效 daylight illuminance 表达。

讲白一点：DER 比较像原材料特性；EDI 比较像在某个使用条件下的换算结果。

这就像你不能把某颗 LED 在某个距离下的中心照度，当成灯珠的固有属性一样。
同理，你也不应该把一个没有写明前提条件的 EDI，包装成灯珠自身的绝对能力。

所以，如果一份 datasheet 上写：melanopic EDI = 86 lx

但没说明这是：

• 对应多少 photopic illuminance
• 基于什么 SPD 分辨率
• 在什么 If / Tj 条件下测得
• 是否为归一化条件
• 是否只是 source-level 换算值

那么这个数字，严格来说，技术含量是可疑的。

不是因为 EDI 不能写，而是因为不带条件写 EDI，本身就是一种不完整。

---

5. 上游企业现在真正缺的，不是一个新参数，而是第五套模型。

我想把这件事说得更系统一点。今天成熟的 LED 企业，基本上都已经建立了四套模型：

第一套：电模型
If、Vf、功耗、驱动范围、调光特性。

第二套：热模型
Tc、Tj、热阻、降额曲线、热失效风险、寿命边界。

第三套：光模型
光通量、CCT、色坐标、bin、显色、TM-30、色漂、光谱。

第四套：可靠性模型
LM-80、维持率、封装稳定性、失效率、环境适应性。

但是到了今天，如果还要真正往“健康光”“节律光”“高品质光谱价值链”走下去，企业就必须补上第五套：

第五套模型：生理光谱模型

这才是 CIE S 026 真正对 LED 上游提出的要求。不是叫你在 PPT 上加一页 α-opic，而是叫你开始建立这样的能力：

• 五类 α-opic DER
• 五类 α-opic EDI
• 它们与 SPD 的对应关系
• 它们与电流、结温、老化、binning 的关联
• 它们如何进入混光、调光、场景算法与下游应用设计

这才是懂 CIE S 026 的企业，而不是只会说一句“我们的产品支持健康照明”。

---

6. 真正厉害的灯珠企业，规格书会这样写。

我讲一个很务实的判断标准。未来你看一家 LED 灯珠企业是不是走在前面，不要先看他简报里有没有 human-centric lighting。

先看他规格书怎么写。我认为，一家真正往前走的企业，至少会分三层来做。

第一层：主表先把五类 α-opic DER 建起来。

这是最核心的基本盘。不是只写 melanopic。
而是逐步把：

• S-cone-opic DER
• M-cone-opic DER
• L-cone-opic DER
• Rhodopic DER
• Melanopic DER

建立成标准输出。因为这才是对 CIE S 026 最基本的尊重。你不能嘴上说自己在做 α-opic，结果最后只拿一条最方便卖的数字出来。

第二层：EDI 可以写，但必须是“有条件的 EDI”。

例如：

• Melanopic EDI @ 100 lx
• Melanopic EDI @ 300 lx
• 甚至五类 α-opic EDI @ 100 lx / 300 lx / 500 lx

这种写法就合理得多。因为它承认 EDI 是基于 photopic illuminance 换算出的结果，而不是把它假装成一个脱离条件的绝对值。

第三层：把 α-opic 与电热漂移、老化、binning 打通。

这一步才真正拉开差距。因为如果你的 α-opic 数值不会随 If、Tj、aging 改变，那只有两种可能：

• 要么你产品神到违背物理，
• 要么你根本还没真的开始建模。

所以，未来更高水平的 datasheet 应该开始出现：

• α-opic DER vs. current
• α-opic DER vs. junction temperature
• α-opic shift after aging
• α-opic distribution by bin

到这一步，α-opic 才真正从概念变成可交付能力。

---

7. 今天最值得警惕的，是“melanopic 单一崇拜”

我其实很能理解，为什么市场上会快速聚焦 melanopic。因为它最容易讲，也最容易跟日间提神、夜间抑制、WELL、昼夜节律等应用连上。

但我要很坦白地说：如果整个产业最后把 CIE S 026 收敛成“谁的 melanopic 比较高”这种单一竞赛，那我们只是把过去拼 lm/W 的老路，换了一个更时髦的词重演一次。

这不是产业升级，这只是口号升级。因为真正的光环境，从来不是只看单一通道；真正的人的反应，也从来不是只靠一个值就能概括。

所以我非常主张一件事：在传播上，可以先从 melanopic 切入；但在技术底层，一定要回到五类 α-opic 的完整框架。

否则后面一定会出现一堆“高 melanopic 但整体光品质很差”的产品，或者一堆“拿单一值过度承诺生理效果”的市场话术。

那不是我期待的未来。

---

8. 这不是技术细节，而是上游企业下一轮定价权。

很多人会把这篇文章看成技术话题。我不这么看。 我认为这其实是产业话语权的问题。

过去十多年，LED 行业上游能掌握价值，靠的是什么？不是因为谁最会讲故事，而是因为谁掌握：

• 更好的封装能力
• 更稳定的binning
• 更成熟的可靠性模型
• 更完整的应用支持
• 更高效的规格语言

今天到了 CIE S 026 时代，这套游戏并没有变，只是竞争维度升级了。

未来真正高价值的灯珠企业，不只是能说“我们有某某波段、某某配方、某某显色”，而是能说： 我们这颗 LED，不仅光效高、颜色准、可靠性稳； 它的五类 α-opic 特征是可定义的、可重复的、可运算的、可进入系统设计的。

一旦做到这一步，你卖的就不只是灯珠。你卖的是：可被下游直接调用的光谱能力。而这，才是真正能撑起下一轮溢价的东西。

---

9. 别急着喊“健康照明”，先把规格书写对

如果让我给 LED 灯珠制造商一个最直接的建议，我会说：别急着在展台上喊自己懂健康光，先回去看看你的 datasheet。

如果你的规格书还只能描述：

• 多亮
• 多省
• 多白
• 多高显色
• 多低色差

却还不能描述：

• 这颗 LED 的五类 α-opic 特征是什么？
• DER 与 EDI 如何定义？
• 与电流、结温、老化如何耦合？
• 下游客户如何将它接入场景与人的模型？

那么你离真正的“健康光元器件企业”，恐怕还有一段距离。不是因为你的技术不够，而是因为你的产业语言，还没升级。

而我相信，下一轮真正有机会拿到话语权的，不是最早喊口号的人，
而是最早把这套语言——写进规格书、做进工具箱、接入应用链、变成交付能力的人。

这才是 CIE S 026 对 LED 上游真正的意义。不是多印几个参数，而是重写规则。

---

Conclusion

未来客户买的，不只是流明。
他们买的，是一颗 LED 能否被准确放进“人”的模型里。

这些年，照明行业越来越喜欢谈几个词： 健康照明、人因照明、昼夜节律、低频闪、高显指、智慧控制。

听起来都对。但很多时候，问题也恰恰出在这里。

因为太多人以为，只要把几个「正确参数」拼在一起，就等于做出了「更健康的光」。

于是行业里出现了大量看似先进、实则片段化的表达：

把高显指当成健康光，把可调色温当成节律光，把低频闪当成高品质，把智慧系统当成最终答案。

但如果认真看 WELL，尤其是今天再回头看 WELL v2 的 Light 概念，你会发现它要说的，其实远不止这些。

WELL光概念，不是9个条款。

它真正试图推动的，是照明行业从「卖灯、卖参数、卖控制」这套旧逻辑，转向「交付对人真正有效的光环境」这套新逻辑。

对我而言，这不是一次普通的标准更新。这更像是一面镜子，逼着整个行业重新回答一个根本问题：

我们到底是在做照明，还是在做与人有关的光？

---

1. WELL为什么值得今天重新认真读一遍？

我一直认为，WELL 对照明行业最重要的地方，不是它是不是一套认证标准。

而是它逼着这个行业重新面对一个根本问题：

我们到底是在卖照明设备，还是在交付人的光环境体验与健康结果？

这是两个完全不同的生意。

前者的逻辑，是拼价格、拼效率、拼外观、拼交期、拼协议。

后者的逻辑，是拼理解人、理解空间、理解时间、理解测量、理解控制、理解长期表现。

过去行业里很多所谓「健康照明」的讨论，之所以走不深，不是因为大家不努力，而是因为大家还在用旧时代的方法，处理一个新时代的问题。

用过去「灯具导向」的思维，去做今天「人导向」的课题，当然会不够。

而 WELL 的价值，就在于它不是停留在一句「健康很重要」的道德判断上。

它试图把这件事拆成一套真实可执行的系统语言：

• 你怎么设计?
• 怎么选型？
• 怎么证明？
• 怎么测试？
• 怎么运行？

所以，今天重看 WELL，不是因为它「流行」。 而是因为它正在越来越接近行业未来真正需要的底层能力。

---

WELL光概念，表面是9个条款，底层是一整套方法论

很多人第一次看 WELL Light，会把它理解成一组 feature 清单。 L01 到 L09，逐条对照，逐条满足。

这样看当然没错。但如果只看到这里，其实只是看到了表层。

因为 WELL 光概念真正厉害的地方，不在于它列出了 9 个条款，而在于这 9 个条款背后，已经隐含了一套完整的方法论：

光接触 →视觉可见 →节律支持 →眩光控制 →日光协同 →视觉平衡 →电气品质 →用户控制

这不是简单的清单。这是一整套关于“什么才叫好光环境”的结构化答案。

What should good light really do for people in space?

说得更直白一点：

过去行业思维常常是，灯具选好了，照度够了，控制有了，这事就差不多了。

但 WELL 的逻辑不是这样。它在追问的是：

• 这个空间里的人，有没有获得足够且合适的光接触？

• 这个光是不是支持视觉任务，而不是制造疲劳？

• 这个光会不会支持白天清醒，却破坏夜晚休息？

• 这个光会不会造成眩光？

• 这个空间有没有把日光用好？

• 光环境是否平衡，而不是忽明忽暗、冷暖混乱？

• 灯具品质是否足够，显色和频闪是否过关？

• 用户能不能真正掌控自己的光环境？

当一套标准开始用这样的方式提问时，它其实已经不再只是定义“照明”，它是在定义“人和空间之间的光关系”。

---

3. 这场重构，第一刀砍向的就是“参数崇拜”。

我认为，WELL 对照明行业最深的一刀，就是它在动摇行业长期以来最习惯的那种参数崇拜。

过去大家太容易相信一件事：只要我有几个好参数，我就是好产品；只要我能讲出几个先进概念，我就是好方案。

但 WELL 给出的答案是： 不够。

举个最简单的例子。一个项目可以有不错的 CRI，也可以有可调色温，甚至还可以做出某种节律照明叙事。但如果这个空间眩光很强、亮度分布失衡、频闪控制不佳、用户无法调节、夜晚策略混乱，那它依然不是一个真正高品质的光环境。

这件事听起来像常识，但行业里真正做到的人并不多。因为参数是最容易营销的，而系统能力，是最难营销、也最难伪装的。

参数可以截图。系统能力要靠项目结果说话。 参数可以在展会海报上放大。系统能力要贯穿设计、施工、调试、验证和运营的全过程。

所以从这个角度看，WELL 真正重构的，不只是技术语言，更是行业的价值判断标准。

---

4. 为什么我说它不是条款，而是价值重构？

因为它重新定义了

“谁更有价值”

在旧逻辑里，最有价值的人，通常是最会做产品的人。或者说，是最会把产品卖出去的人。 但在 WELL 逻辑下，真正有价值的人，会逐渐变成下面这几类：

第一类，真正理解人的人。

不是只会看参数，而是理解光如何影响视觉、情绪、清醒度、疲劳感与作息体验。

第二类，真正理解空间的人。

知道光不是抽象存在，而总是发生在建筑、立面、朝向、材料、任务和行为之中。

第三类，真正理解时间的人。

知道白天和夜晚不是同一回事，清醒和休息不是同一回事，办公、教育、医疗、住宅、酒店也不是同一回事。

第四类，真正理解验证的人。

知道今天的照明项目，已经不能只靠设计表达，而必须靠技术文件、模拟、测试与可追溯证据来完成交付。

第五类，真正理解运营的人。

为再好的光，如果离开调试、维护和使用场景，很快就会从“设计效果”变成“现实妥协”。

这就是为什么我说，WELL 光概念表面看是 feature，本质上却是在改写行业里“谁值得被高估”的标准。

---

对于照明公司来说，最该升级的不是营销，而是证据链。

很多照明公司现在已经会讲 WELL 了。 但我坦白说，大多数还是停留在“会讲”阶段。

真正的问题是： 你到底是在支持 WELL，还是在借 WELL 说故事？

如果真的要进入 WELL 项目逻辑，照明公司最该升级的，不是宣传页，而是证据链。

你不能只说“我们高显指”。你要能说明，在不同色温、不同调光状态下，显色是否依然成立。

你不能只说“我们低频闪”。你要能提供清晰的测试依据与适用条件。

你不能只说“我们支持眩光控制”。你要能证明你的数据与真实空间设计条件相匹配。

你不能只说“我们可以做智能控制”。你要能说明控制分区、场景逻辑、用户界面、兼容性以及最终可用性。

未来真正有竞争力的厂家，不是那个 PPT 做得最好看的，

而是那个最能帮项目团队降低不确定性、提高落地率的。

换句话说，客户买的不是灯。客户买的是： 你能否让项目更稳地被设计出来、被证明成立、被测试通过，并在后期继续运行得像样。

---

6. 对设计师来说，真正的分水岭来了

过去做照明设计，很多时候核心是“布灯”。再往前一步，是“做氛围”。再进一步，是“做场景控制”。

但现在，如果你真的要面对 WELL，或者更广泛地面对健康光环境趋势，设计师的分水岭已经不在这些层次上了。

真正的分水岭是： 你做的是灯具配置，还是光环境建构？

这两个概念差别非常大。灯具配置，是把产品放进空间。

光环境建构，是把人的行为、视线、任务、时段、节律与空间结构一起纳入判断。

所以今天真正优秀的设计师，不能只会算平均照度。

还要会看：

• 人在不同姿态下接收到什么光
• 视平线附近的亮度与对比是否舒服
• 白天的日光是否被合理利用
• 夜晚的刺激是否被有效压低
• 相邻区域是否失衡
• 色温、显色与控制逻辑是否一致
• 场景是否真实可用，而不是为了汇报好看

说得再直白一点： 未来不会缺“会做灯光效果图”的设计师。

未来真正稀缺的，是能把健康主张做成空间结果的设计师。

7. 经销商和渠道商，也不能再只是搬货了

这一点很多人容易忽略。但我认为，WELL 对经销商的影响其实非常大。

因为当项目越来越复杂，客户真正需要的就不再只是“哪个品牌有货、哪个型号便宜”。

客户需要的是有人告诉他：这几个条款里

• 哪些是产品直接支持的？
• 哪些是设计层面解决的？
• 哪些需要控制系统配合？
• 哪些需要现场测试才能闭环？

这时候，经销商如果还是只会背价格单、背折扣、背交期，价值会越来越薄。

反过来，谁能整合产品资料、控制能力、应用经验与项目理解，谁的角色就会从“供货渠道”变成“项目协同者”。

这就是价值重构在渠道端的真实表现。

---

One WELL 正在释放一个越来越清晰的信号

很多人关心的是：下一版会不会改参数？会不会调整门槛？会不会新增条款？

这些当然重要。但在我看来，更重要的是它释放出来的整体方向。

这个方向其实越来越明确： WELL 正在持续将“健康”从一个善意的理念，推进为一个更清晰、更精确、更可实施的行业框架。

这对照明行业意味着什么？意味着以后越来越难靠模糊表达蒙混过去。

越来越多的事情都需要被问清楚：

• 你的设计依据是什么？
• 你的参数适用于什么条件？
• 你的产品如何支持真实空间？
• 你的控制策略是否真的可用？
• 你的现场测试怎么完成？
• 你的后期运营如何维持效果？

这对行业当然是压力，但我认为，这也是好事。

因为一个行业真正成熟，不是靠所有人把故事讲得越来越大，而是靠所有人更愿意面对证据、面对边界、面对真实交付。

---

最后，WELL 真正重构的是行业的自我认知。’s self-understanding

写到这里，我其实最想说的一句话是： WELL 光概念，真正改变的，不只是项目做法，而是行业如何看待自己。

如果我们还把自己看作“照明产品行业”， 那未来无非就是继续卷效率、卷价格、卷功能堆叠。

但如果我们开始把自己看作“光环境能力行业”， 那一切都会不一样。

我们会更认真地看待：

• 光与睡眠的关系
• 光与认知表现的关系
• 光与情绪的关系
• 光与空间运营的关系
• 光与长期健康体验的关系

那时，灯具依然重要。控制依然重要。系统依然重要。

但它们都不再是终点。它们只是手段。

真正的终点，是： 让光更好地服务于人。

而 WELL v2 的 Light 概念，连同正在推进中的 One WELL，真正想推动的，正是这件事。

所以我才会说： WELL光概念，不是9个条款。 而是一场照明行业的价值重构。

⸻

Closing lines

过去，我们习惯问：这盏灯够不够亮？够不够省？够不够智能？

未来，我们更应该问： 这束光，是否真的对人更好？

当这个问题成为行业共识的那一天， 照明行业才算真正进入了下一阶段。

LRS × Traxon | Lighting is becoming Infrastructure

在法蘭克福，Light + Building 2026。

一個看似普通的合作官宣，其實隱藏著一個不普通的信號。

Lighting Recipe Studio × Traxon Technologies Limited

如果你只是把它看成：一次企業合作

那你可能錯過了真正重要的東西。

---

一、照明行業，其實已經換了一套邏輯

過去十年，照明行業其實走了兩條路。

一條路，在做「系統」

• 智能照明
• 控制平台
• IoT / BMS
• 城市級光環境

系統越來越強

一條路，在談「人」

• Human Centric Lighting (HCL)
• 晝夜節律
• Melanopic metrics
• 睡眠 / 情緒 / 健康

理論越來越多

但問題是：這兩條路，從來沒有真正連在一起

系統，不理解人
科學，無法落地

二、這個問題，為什麼嚴重？

因為整個行業，其實一直在「錯位進步」。

燈變得更智能
系統變得更複雜

但光，仍然沒有被真正理解。

---

三、這次合作真正的意義

不是合作本身。

而是：把「光的科學」，放進「光的系統」

光，不再只是被設計
光，開始變成「可以被測量與管理的變量」

四、為什麼 Sympholink 是關鍵？

很多人會把它當作一個 lighting control system。

但實際上：它正在變成一個「光的操作系統」

當系統開始接入：

• SPD（光譜）
• Melanopic metrics
• Flicker
• 時間（節律）

光，第一次變成可以被“經營”的東西

五、照明的三個時代

Lighting 1.0
照亮世界

Lighting 2.0
智能控制

Lighting 3.0
Healthy Light Infrastructure

光，從產品 → 系統 → 基礎設施

六、競爭邏輯已經改變

過去，照明行業比的是：

• 誰更亮
• 誰更省電

未來，照明行業比的是：誰更理解「人」

---

七、LRS × Traxon 的真正優勢

這次合作，難得之處在於：

1️⃣ 科學 × 系統（真正打通）

• LRS → 光的科學與測量
• Traxon → 光的系統與全球落地

2️⃣ 光開始變成「資產」

• 可測量
• 可優化
• 可管理

3️⃣ HCL 從概念走向系統

• 不再只是設計語言
• 而是系統能力
• (測量設備 / 數據 / 應用場景）

八、一個更現實的問題

未來，照明行業可能只剩兩種公司：

做燈的
做光環境的

你在哪一邊？

---

Conclusion

照明的未來，不只是光。

而是：人 × 系統 × 數據 × 生命

最後一句

很多人還在做燈，但照明行業，已經變了。

As lighting becomes more connected, automated, and intelligent, the industry must not lose sight of its deeper mission: creating healthier, more meaningful, and more valuable human environments.

When technology moves fast, purpose must move even faster.

Light + Building 2026 has ended, but one question remains:

As our industry becomes more electrified, more connected, more automated, and more intelligent — are we still clear about what all of this is for?

According to Messe Frankfurt’s official final report, the 2026 edition brought together 1,927 exhibitors from 49 countries and 144,767 visitors from 143 countries, once again confirming the scale and global relevance of the fair. The official review highlighted the rapid advance of electrification, digital connectivity, AI-supported systems, multifunctional interfaces, and adaptive building technologies.

All of that matters.

But after walking the halls, attending meetings, speaking at Design Plaza, and listening to industry conversations across multiple layers of the value chain, I came away with a stronger conviction:

The lighting industry must be careful not to become more sophisticated in its tools while becoming less clear about its purpose.

1. Light + Building 2026 showed an industry rich in innovation

There is no doubt that the industry is advancing quickly.

This year’s fair made that very visible: connected systems, controls, sensors, AI-supported building management, integrated energy infrastructure, and increasingly responsive environments all pointed in the same direction — lighting is no longer operating as an isolated product category, but as part of a larger building intelligence ecosystem.

That shift is real, necessary, and strategically important.

We are clearly moving from standalone luminaires to integrated systems, from isolated devices to connected architecture, and from hardware performance to programmable, measurable, adaptive environments.

This is progress.

But progress alone is not a compass.

Because the essential question is not whether the industry can build smarter systems.

The essential question is: What kind of human value are those systems ultimately meant to create?

2. The danger is not lack of technology — it is loss of center

Our sector has become highly fluent in the language of systems:

connectivity, controls, automation, data, AI, interoperability, digital infrastructure, predictive maintenance, adaptive buildings.

These are powerful capabilities.

But they are still only capabilities.

If we are not careful, we risk describing the future of lighting mostly through its technical architecture, instead of through its human contribution.

That is where an industry can gradually lose its center.

Because light is not only technical.

Light influences vision, of course. But it also influences biology, mood, alertness, recovery, comfort, productivity, behavior, and emotional experience.

It shapes not only what we see, but also how we feel, how we function, and in many cases how we live.

So if lighting becomes merely another connected layer in the building stack, stripped of its human meaning, then even our most advanced systems may become strategically hollow.

3. This is why the HCL roadmap still matters

At this point, I believe it is worth returning to an industry direction that should never have been treated as secondary: the Human Centric Lighting roadmap.

LightingEurope’s own vision states it very clearly:

“The increased Value of Lighting will come from Intelligent Lighting Systems and Human Centric Lighting.”

That sentence deserves to be read carefully.

It does not say the future value of lighting will come from connectivity alone. It does not say it will come from controls alone. It does not say it will come from energy efficiency alone.

It says the increased value of lighting comes from two pillars together: Intelligent Lighting Systems and Human Centric Lighting.

That is a crucial distinction.

Because it reminds the entire industry that intelligence without human relevance is incomplete.

It is not enough for lighting to become smarter. It must also become more beneficial.

4. The broader GLA roadmap carries the same warning

The strategic roadmap associated with the global lighting industry reinforces the same point.

It explicitly calls on the industry to promote the fact that lighting does much more than enabling vision, and to make Human Centric Lighting part of the healthy building movement and building standards.

This is not just policy language.

It is a reminder of original intent.

The industry did not invest in better LEDs, optics, drivers, controls, measurement, connectivity, and software merely to create more layers of automation.

We did so because we believed lighting could become more valuable to life.

More supportive of health. More responsive to human rhythms. More meaningful in experience. More effective in work, education, hospitality, care, and recovery. More sustainable not only in energy terms, but in long-term value.

That is why I say this to the whole industry now:

Do not forget why we started.

We started because light matters to people.

5. Human Centric Lighting should not remain a niche

One of the industry’s persistent weaknesses is that HCL is still too often treated as a specialist topic, a premium concept, or a separate layer of innovation rather than a central direction for mainstream value creation.

That is no longer enough.

If intelligent systems are moving to the center of our market strategy, then human-centric purpose must move there too.

Not because every project needs a complicated theoretical framework.

But because the principle itself is simple: Technology should improve human outcomes.

This means the next phase of lighting should not only ask: Can it be connected? Can it be controlled? Can it be measured? Can it be monetized?

It must also ask: Does it support healthier rhythms? Does it improve comfort? Does it reduce stress? Does it support performance? Does it improve emotional quality? Does it make the space more humane? Does it increase long-term value rather than short-term novelty?

These are not soft questions.

They are strategic questions.

And if the lighting industry does not answer them clearly, others will answer them for us.

6. The next chapter of lighting must move from systems to outcomes, and from outcomes to value

In my view, the industry’s next evolution should be understood in three steps:

From products to systems. This transition is already happening.

From systems to outcomes. This is where many companies are now competing.

From outcomes to human value. This is where the next real differentiation will happen.

And that human value, in my view, should be framed around four interlinked priorities:

Sustainability. Health. Productivity. Emotional value.

Not one instead of the others.

Not one trend this year and another next year.

All four.

Because real people do not experience buildings in isolated technical categories.

They experience them as living conditions.

And light is one of the most powerful conditions of all.

7. ‘Do not forget the original aspiration’ is not a call backward — it is a call upward

To remind the industry of its human-centered purpose is not to reject innovation.

It is the opposite.

I am not arguing against electrification. Not against digitalisation. Not against AI. Not against integrated building systems.

All of these are necessary.

But they must be re-anchored in purpose.

The point is not to slow down technology.

The point is to elevate its meaning.

Because the next frontier is not simply smarter lighting.

It is more valuable lighting.

Valuable because it supports better sleep and better wakefulness. Valuable because it improves visual, biological, and emotional conditions. Valuable because it enhances comfort, performance, and human experience. Valuable because it fits into circular, adaptable, serviceable long-life systems. Valuable because it makes buildings not just intelligent, but worth inhabiting.

That is where HCL, intelligent lighting systems, measurement, controls, and sustainability can converge.

Not as separate agendas.

But as one larger industrial mission.

8. What Light + Building 2026 should remind us

Light + Building 2026 demonstrated that our sector remains innovative, capable, and globally relevant. Messe Frankfurt’s review makes that abundantly clear.

But beyond the scale and innovation, the fair also leaves us with a more important reminder:

An industry can become very advanced in its tools and still fall short in articulating its higher purpose.

That is why the HCL roadmap still matters.

That is why the GLA perspective still matters.

That is why the human value of light must not be treated as a side discussion.

And that is why this message matters now:

Do not let electrification become the ceiling of imagination. Do not let connectivity replace purpose. Do not let intelligence drift away from humanity. Do not forget why we started.

We started because light is not only technical. It is biological. It is emotional. It is spatial. It is cultural. It is human.

And for LRS, that remains the core belief:

Good light should not only be smarter. It should be more purposeful, more human, and more valuable to life.

In Part I, we reviewed an article cited by LRS’s U.S. partner LEDmetric:

“The Light Revolution: Top Three 2026 Light Studies That Change Everything.”

Based on three categories of studies, the article presented relatively aggressive, highly communicative conclusions:

• High ultraviolet exposure is associated with lower mortality
• LED environments lacking near-infrared may affect mitochondria
• Natural light may help stabilize blood glucose

On social media, these findings were further amplified into simplified messages:

• “LED may be harmful”
• “We should return to full-spectrum light sources”

In the first two parts of this trilogy, we established three core models: dose, spatial, and human factors.

This final part addresses two key questions:

What does the scientific system actually support?
And how should the industry rationally upgrade its development path?

---

I. Social Media Narratives vs. the Scientific System

1️⃣ CIE S 026 Does Not Define a “Healthy Light Source”

CIE S 026 provides:

• A weighted calculation framework for five photoreceptors.

It does not:

• Recommend any specific light source
• Reject LEDs
• Promote incandescent lamps

It does only one thing:

• Provide a calculable spectral weighting method.

换句话说：

Science provides evaluation tools, not emotionally driven conclusions.

---

2️⃣ The Real Meaning of Melatonin Suppression Research

Classic studies (e.g., Lucas et al., Brown et al.) show that:

• Melatonin suppression correlates with melanopic stimulus intensity.

But their core findings are that:

• There is a dose–response relationship
• There is time dependence
• There are individual differences

They do not conclude that:

• “Any particular light source is inherently harmful.”

---

3️⃣ IEEE 1789 and the Flicker Issue

Flicker risk assessment provides guidance on neurological safety.

Its focus is on:

• Waveform modulation
• Frequency ranges

—not on the type of light source itself.

---

4️⃣ The Position of the WELL Light Concept

WELL emphasizes:

• Daytime circadian support
• Nighttime circadian protection
• Vertical illuminance
• Equivalent Melanopic Lux

But it does not advocate a return to incandescent lighting.

What it emphasizes is:

• Verifiable light exposure structures.

---

II. Should We “Return to Incandescent Lamps”?

We must be clear:

We do not support a simple return to incandescent lighting.

Reasons include:

1️⃣ Energy efficiency and carbon emissions
2️⃣ Insufficient spectral controllability
3️⃣ Limited dynamic adjustability
4️⃣ Incompatibility with modern smart building systems

The advantage of natural light lies not in “light source technology,” but in:

• Dynamic structure
• Continuous spectrum
• Temporal variation

Industry upgrading should not mean technological regression, but rather technological integration.

---

III. The Real Path Forward: Multi-Band Semiconductor Integration

The future is not:

• “LED vs. incandescent,”

but rather:

• Controllable, multi-band semiconductor integrated systems.

Including:

• Optimized full visible-spectrum coverage
• Precise regulation of melanopic ratios
• Integration of near-infrared (NIR) bands
• Dynamic temporal control
• Integration with control systems

NIR has been amplified in recent research discussions.

However, it must be emphasized:

If NIR is introduced, we must answer:

• What is the appropriate dose range?
• How are long-term exposure thresholds defined?
• Are there tissue-level differences?
• Do we have measurement and verification methods?

All of this must be built on a rigorous engineering framework.

---

IV. Causation vs. Correlation: The Boundary of Industry Communication

In discussions of healthy lighting, it is essential to distinguish between:

• Epidemiological correlations
• Short-term intervention studies
• Mechanistic basic research
• Long-term causal validation

Industry communication must avoid claims such as:

• “A certain spectrum cures disease”
• “A certain light source is inherently harmful”

The correct framing should be:

Under specific dose and temporal structures,
certain spectral combinations may support particular physiological pathways.

This is not only a matter of scientific rigor, but also of industry responsibility.

---

V. LRS’s Scientific Expression Framework

In building the light exposure management ecosystem, we consistently adhere to four principles:

1️⃣ Biological plausibility
– Alignment with established physiological research

2️⃣ Clear dose boundaries
– Defined intensity and time ranges

3️⃣ Spatial feasibility
– Achievable through engineering implementation

4️⃣ Long-term verifiability and repeatability
– Measurable and re-measurable

This framework is why we reject “slogan-based upgrades.”

The positioning of the In. Licht device series and algorithm platform was formed within this framework:

• Not to claim “healthier” lighting,
• But to provide measurable, verifiable, and repeatable exposure-management tools.

---

VI. The Direction of Industry Ecosystem Upgrading

The future industry structure will likely take the form of a three-layer architecture:

Layer 1
Embedded spectral sensing nodes (integrated with control systems)

Layer 2
Verification-grade reference instruments (full visible-spectrum coverage, expandable to NIR)

Layer 3
Professional analytical software platforms (supporting research, design, and WELL projects)

This is not merely a device upgrade, but an ecosystem upgrade.

---

VII. Conclusion: What Is the Real “Light Revolution”?

The true revolution is not a return to the past, but:

• From “light source debates” 至 “light exposure management”
• From “parameter stacking” 至 “structural models”
• From “emotional narratives” 至 “verifiable ecosystems”

Only when the industry possesses:

• Structured models
• Standard-alignment capability
• Multi-band integration technologies
• Measurement and re-measurement mechanisms

will discussions of light and health truly mature.

---

Complete Series

Light Exposure Management Trilogy

• Part I: Research Hype and Rational Frameworks
• Part II: Dose–Space–Human Models
• Part III: Scientific Benchmarks and Industry Pathways

In the previous article, we discussed:

How the industry can avoid emotional interpretations when overseas research is amplified by social media. But the real question is not how to correct misreadings.

Rather, it is this:

Do we actually have the capability to understand light exposure in a structured way?

Without models, research remains fragmented. Without structure, engineering can only rely on experience.

In this article, we will systematically introduce three core models:

• Dose Model
• Spatial Model
• Human Model

and discuss how they connect with international standards frameworks.

---

I. Dose Model: Light Is Not “Good” or “Bad,” but “How Much × When”

For a long time, industry discussions around light focused mainly on three metrics:

• 照度（lux）
• 相关色温 (CCT)
• 显色指数（CRI）

However, with deeper circadian research and the release of CIE S 026, we are gradually realizing:

Human responses to light are not governed by a single visual channel.

---

1️⃣ The Significance of the α-opic Framework

CIE S 026 introduced five photoreceptor-weighted systems:

• S-cones
• M-cones
• L-cones
• Rods
• Melanopsin (ipRGC)

Among them, melanopic Equivalent Daylight Illuminance (m-EDI) has become a key metric for evaluating circadian stimulus.

The introduction of this framework marks the lighting industry’s transition into a multi-spectral evaluation era.

However, it must be emphasized: α-opic metrics are not “the higher, the better.”

They must be understood in conjunction with time structure.

---

2️⃣ Temporal Structure: The Critical Variable Often Ignored

The same m-EDI value:

• In the morning → promotes alertness
• At night → suppresses melatonin secretion

Therefore, a dose model must include:

✔ Spectrum
✔ Intensity
✔ Exposure duration
✔ Circadian phase

A complete expression:

Dose effect = f (spectrum × intensity × time × phase)

Without the time dimension, any discussion of α-opic metrics is incomplete.

---

3️⃣ Alignment with WELL

"(《世界人权宣言》) WELL v2 Light Concept increasingly emphasizes:

• Vertical illuminance
• Equivalent Melanopic Lux
• Daytime circadian support
• Nighttime circadian protection

This indicates that standards are shifting from visual satisfaction toward physiological appropriateness.

In practice, the industry must possess:

• On-site spectral measurement capability
• α-opic calculation capability
• Temporal evaluation capability

When LRS developed the In. Licht algorithm framework, it was precisely to address this need:

Not merely displaying SPD curves, but synchronizing α-opic weighting with spatial illuminance output, helping designers understand dose structure.

---

II. Spatial Model: What the Human Body Receives Is “Light Reaching the Eye”

Lighting design has long emphasized horizontal illuminance. But circadian research repeatedly shows:

Vertical illuminance at eye level is the key variable.

This means that:

• Luminaire layout
• Light direction
• Spatial scale
• Surface reflectance
• Architectural openings

all reshape the actual exposure structure.

---

1️⃣ The Advantage of Daylight Lies Not in “Wavelength,” but in “Structure”

Natural light provides:

• Spectral continuity
• Dynamic intensity changes
• Diurnal color temperature variation
• Spatial gradient distribution

In contrast, many indoor environments feature:

• Constant spectra throughout the day
• Uniform illuminance
• Lack of temporal rhythm

The absence of rhythmic information can blur physiological signaling.

Therefore, a spatial model must include:

✔ Vertical illuminance
✔ Dynamic curves
✔ Zoning strategies
✔ Light distribution gradients

---

2️⃣ Flicker: A Neural-Level Variable

Flicker is often overlooked. IEEE 1789 provides a framework for flicker safety guidance.

Flicker can affect:

• Visual comfort
• Neural fatigue
• Long-term perceptual stability

Within a light exposure management system, flicker must be evaluated in parallel with spectrum and illuminance.

This means the industry needs integrated measurement capabilities, not isolated parameter judgments.

---

3️⃣ The Need for Ecosystem Integration

Integrating dose and spatial models requires:

• Multi-spectral acquisition
• Vertical illuminance measurement
• Flicker analysis
• Temporal recording

This is not a single-device issue, but an ecosystem capability issue. In recent years, LRS has attempted to build an integrated framework of:

Measurement nodes + algorithm engine + reporting structure

"(《世界人权宣言》) In. Licht series serves as an on-site node, but the true core lies in: structured model integration capability.

---

III. Human Model: Healthy Light Must Be Layered

A common industry misconception is:

Designing one single type of “healthy light” for everyone. But human responses vary significantly.

---

1️⃣ Age Differences

Lens yellowing with age → reduced blue-light transmission. The same spectrum delivers different effective doses to different age groups.

---

2️⃣ Schedule Differences

• Night-shift workers
• Rotating-shift workers
• People with chronic insomnia

Circadian-misaligned populations require different strategies.

---

3️⃣ Metabolic and Health Backgrounds

People with diabetes, depression, or chronic inflammation may respond differently to light exposure structures.

International trends are moving toward: Layered design, scenario-based strategies, and dynamic management.

---

IV. Complete Structural Expression

Integrating all three models:

Light effect = f (spectrum × intensity × time × space × individual differences)

This is not theoretical showmanship, but a necessary condition for engineering advancement.

Only when the industry possesses:

✔ Multi-spectral measurement capability
✔ α-opic calculation capability
✔ Flicker analysis capability
✔ Dynamic curve modeling capability
✔ Human-factor stratification frameworks

can it truly enter the structured era.

---

V. From Models to Ecosystem

Future competition will not be about: Who makes the brightest lamp.

But about: Who can build a complete light exposure structure model, align it with CIE, WELL, IES, and other systems, and form a verifiable, repeatable engineering loop.

In the next article, we will discuss:

How to establish a responsible light exposure expression system within a scientific control framework, and why the industry should not simply return to incandescent lamps, but instead explore multi-band semiconductor integration pathways.

---

(To be continued)

Recently, during discussions with our US partner LEDmetric, they cited an article that had been widely shared on overseas social media:

《The Light Revolution: Top Three 2026 Light Studies That Change Everything》

Meet Dr. Max Gulhane, an Aussie doctor who’s been challenging conventional sun exposure guidelines for years, and Jonathan Jerki, a biomedical science student from the US who’s been educating thousands on social media about the critical role of light wavelengths in human health. Together, they’ve just dissected three ground-breaking papers published in 2026 (and it’s only February) that are rewriting what we know about sun exposure, longevity, and metabolic health. Let’s dive in….

Study #1: Why Sun Avoiders Die Younger

Richard Weller (yes, the Edinburgh dermatologist we’ve mentioned before) just dropped what might be the most important sun exposure study ever published.(https://www.medrxiv.org/content/10.64898/2026.01.08.26343592v1) Using the massive UK Biobank dataset with over 400,000 participants, his team created something called the “Sun-BEEM score” to categorise people’s UV exposure as low, medium, or high.

Here’s what he found: those with the highest sun exposure had a 16% reduction in all-cause mortality and a whopping 23% reduction in cardiovascular death compared to sun avoiders. And here’s the kicker—they saw a perfect dose-dependent curve. The more sun, the better outcomes across the board.

But what about skin cancer, I hear you say? Yes, more UV exposure meant slightly more melanoma cases but it’s all about risk vs reward, my friend.

The researchers ran a fascinating thought experiment within this study. Based on their data, they found if everyone fell into the low UV exposure category, you’d prevent 39 melanoma deaths, but you’d cause 3,000 excess deaths from other causes. Flip it around, if you put everyone in the high UV exposure category, you’d save 4,700 lives but lose 23 to melanoma.

The ratio? For every one skin cancer death you prevent by avoiding the sun, you cause 75 deaths from cardiovascular disease and other cancers.

As the researchers bluntly stated: “Overall, these findings challenge the simplistic view that sunlight is primarily a skin carcinogen whose benefits can be replaced by vitamin D tablets and instead, support a more balanced perspective in which UV exposure contributes meaningfully, and not fully substitutable, to the prevention of cardiovascular disease and other major cancers.”

Translation? We’ve been so obsessed with preventing skin cancer that we’ve ignored the elephant in the room—heart disease and internal cancers that are actually killing far more people.

Study #2: Why your LED-lit office is destroying your eyesight

We already covered this study by Glen Jeffery ( https://unstoppables.io/2025/12/06/red-light-heals-plastic-kettle-dangers-ms-explosion-in-australia/) a couple of weeks ago, but here it is again for those that may have missed it. It’s a goodie and worth revisiting.

Glen Jeffery’s team took infrared cameras into a typical UK office building – no windows, glass that reflects infrared light, only LED lighting. When they photographed the environment with infrared cameras, it was essentially a black void. Zero near-infrared light.

Then they did something brilliantly simple: they placed 60-watt incandescent bulbs on workers’ desks for two weeks. That’s it. No other changes.

The results? A 28% improvement in visual function (color contrast sensitivity) that lasted at least six weeks after removing the bulbs. The participants’ eyes were literally getting healthier just from adding back the wavelengths of light their mitochondria desperately needed.

Here’s why this matters: Your retina is one of the most mitochondrial-dense tissues in your body. When you flood it with blue-heavy LED light and starve it of red and infrared wavelengths, your mitochondria can’t produce adequate ATP. Your vision suffers. Your brain suffers. Your entire body suffers.

As Max powerfully stated:

“By putting LED lighting in all of our indoor environments, we are sacrificing our mitochondrial health. We are sacrificing our mitochondrial health in our eye, in our brain, in our heart, throughout our body on the altar of green energy.”

Government regulations prioritised energy efficiency over human health and biology—and now we’re all paying the price. If you’re goal is healthspan and longevity – daily sun exposure is your friend.

Study #3: How the light in your workspace controls your blood sugar—whether you’re eating kale or cookies

In the final study ( https://pubmed.ncbi.nlm.nih.gov/41418772/), researchers took Type 2 diabetics and placed them in two different work environments: one with natural daylight streaming through windows, another with only LED lighting. Same food. Same activity. Only difference? The light.

Those working by windows had more time in normal glucose range and lower 24-hour glucose variability. Why? The dynamic shifting of natural light throughout the day—from orange at sunrise, to blue at midday, back to orange at sunset—sets your circadian rhythm. This rhythm literally controls gene transcription in your muscles, liver, pancreas, and fat tissue. Under static LED lighting? Your body has no idea what time it is. Your metabolic machinery goes haywire.

The Bottom Line

These three studies paint a bleak picture: modern indoor environments are profoundly alien to human biology. We evolved under full-spectrum sunlight from dawn to dusk. Now we’re locked in LED-lit boxes, made to fear UV, starved of infrared and the dynamic light patterns our bodies expect. We all know about the importance of eating a healthy diet and getting adequate exercise and movement in our day, but now we need to discuss light. As Dr Max perfectly summarised: “You can’t out-run or out-eat a junk light diet.”

Your Quick 5 Step Action Plan:

• Get outside daily and regularly — your life literally depends on it
• Add an incandescent bulb to your work desk (seriously, do this today)
• Work near windows when possible.
• Even better, open nearby windows and doors to let the light in
• Remember our goal is to develop a healthy respect and safe relationship with the sun

The science is crystal clear. The question is: will the medical establishment and people wake up before it’s too late? 

This article was written by Dr. Max Gulhane 和 Jonathan Jerki, who analyzed three studies released in early 2026 and provided clear, pointed summaries of their findings.

The article focuses on three categories of research:

1️⃣ UV exposure and all-cause mortality
2️⃣ The potential impact of indoor LED environments lacking near-infrared light on mitochondrial function
3️⃣ The potential effects of natural light environments on blood glucose stability

In social media dissemination, these studies have been further summarized as:

• “Avoiding sun may increase mortality risk”
• “LED lighting is harming our health”
• “We should embrace full-spectrum light sources again”

These statements are highly viral and have begun to enter industry discussions.

As a team long engaged in light environment research and engineering practice, we believe:

These studies are worth serious discussion, but must be understood in a structured way.

---

I. Basic Characteristics of the Studies Cited

1️⃣ UV Exposure and Mortality Study

This study is based on large databases such as the UK Biobank. Researchers created a UV exposure score and analyzed its association with all-cause and cardiovascular mortality.

Findings:

• High UV exposure groups showed statistically lower mortality risk.

However, it is important to note:

• This is observational epidemiology.
• Lifestyle and other confounding variables cannot be fully separated.
• Statistical correlation does not equal causation.

The study presents a possible association, not an engineering prescription.

---

2️⃣ LED Office Environment & Broad-Spectrum Supplementation Experiment

The study added broad-spectrum light in a windowless LED office environment and observed changes in visual metrics.

Results:

• Some improvement in visual contrast sensitivity was observed.

Rational interpretation:

• Small sample size
• Short intervention period
• No conclusions on long-term systemic health

Implication:

• The spectral structure of modern indoor light environments deserves further attention.
• However, the study does not provide a “replacement light source path.”

---

3️⃣ Natural Light and Blood Glucose Stability Study

Findings:

• Diabetic patients working in natural daylight environments had more stable blood glucose fluctuations.

Implication:

• Circadian signals may be linked to metabolic regulation.

请注意：

• The advantage of natural light comes from:
  • Spectral continuity
  • Intensity variation
  • Dynamic temporal structure
  • Spatial distribution differences
• It is not a single wavelength effect.

---

II. Why the Industry is Drawn to the “Light Revolution” Narrative

Light and health naturally attract attention:

• Longevity
• 愿景
• Chronic diseases
• Mitochondria
• Energy metabolism

When complex biological mechanisms are compressed into simplified slogans, binary oppositions emerge:

• LED vs. incandescent
• Artificial vs. natural light

True, mature industry upgrades are structural, not oppositional.

---

III. Core Question: Do We Understand “Light Exposure Structure”?

Instead of asking “Which light is healthier?” the real question is:

Do we have the ability to measure and model light exposure structures?

Health effects of light are determined by exposure structure, not a single wavelength.

Exposure structure includes:

• Spectral composition
• Intensity
• Exposure duration
• Dynamic changes
• Spatial distribution
• Individual differences

Without structured understanding, research hype remains at the opinion level.

---

IV. Industry Turning Point: From “Light Source” to “Exposure Management”

In the past 20 years, the lighting industry focused on:

• 比光效
• Energy consumption
• Cost

With the gradual maturity of CIE S 026, α-opic metrics, and the WELL Light Concept, the industry is entering a new stage:

• From visual satisfaction → physiological support

This means lighting environments must be:
✔ Measurable
✔ Verifiable
✔ Repeatable

LRS efforts over the past few years include:

• Multi-spectral field measurement technology
• α-opic calculation models
• Light exposure structure evaluation frameworks
• Design → verification → operation loop

The In. Licht series was developed in this context—

Not as an isolated product, but as a field node in the light exposure management ecosystem.

---

V. Conclusion: Rationality is a Sign of Industry Maturity

Overseas research is not a threat, but a reminder.

True industry direction is determined not by a single paper, but by whether we can establish:

• Dose models
• Spatial models
• Human factor models
• Standard integration frameworks
• On-site verification capabilities

In the next article, we will systematically discuss:

The three main models of light exposure and their integration with international standards.
