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

這是我於 2026 年 3 月 26 日參加 2026 IWBI 全球顧問啟動會議 後的一點心得。

先說明一點： 這篇文章不是對會議內容的逐條復述，也不是對仍處於公開預覽與 public comment 階段文本的官方解讀。我更想分享的，是在目前 One WELL 已進入公開階段的背景下，它所釋放出來的一個非常清楚的信號：

One WELL，絕不只是一次技術性的標準整合。

它更像是 IWBI 正試圖把 WELL，從一套健康建築認證工具，進一步推向一套更統一、更易實施、更可持續迭代的平台型標準體系。

這也是為什麼，我認為它對產業、對 IWBI 本身，都有比很多人想像中更深的意義。

一、如果不了解 WELL 為什麼會出現，就很難真正看懂 One WELL

過去十多年，建築行業最重要的一股趨勢之一，是綠色建築的快速發展。 無論是節能、低碳、材料、用水，還是環境影響評估，各類綠色建築體系都極大地推動了產業進步。

但行業也慢慢意識到一個問題： 建築變得更綠色了，並不自動等於更適合人。

節能，不等於舒適； 低碳，不等於健康； 系統效率提升，也不等於人的狀態真的更好。

於是， 建築行業開始從「建築是否高效」， 進一步追問「建築是否真正服務於人的健康與福祉」。

WELL 的出現，本質上就代表了這樣一種視角轉向：建築不應只被理解為能源系統，也必須被理解為影響人身心狀態的環境系統。

所以 WELL 最重要的地方，不只是多了一套條款， 而是它把「人」重新拉回到建築評價的中心。

二、One WELL 不是簡單做一個新版本

而是在回應 WELL 成功發展後帶來的複雜性’s Own Success

隨著 WELL 不斷擴展，它的適用邊界越來越廣，影響力也越來越大。 但體系一旦持續成長，複雜性也會隨之上升。

從目前公開釋放出的方向來看，One WELL 所回應的，並不只是「要不要更新標準」，而是更現實的幾個實施問題：標準內容越來越豐富，但理解門檻也隨之提高；多地點、多專案、多版本並行時，管理成本會上升；同類策略在不同場景中的理解與實施，容易出現偏差；而標準更新本身，也需要更可追蹤、更可比較的機制。

所以，One WELL 的出現，不只是為了「做一個新版 WELL」，而更像是在解決 WELL 從成熟走向規模化過程中，必然會遇到的系統摩擦。

換句話說： One WELL 不是從包裝出發， 而是從複雜性治理出發。

三、One WELL 的第一層意義，是去碎片化

很多人第一眼看 One WELL，會覺得它就是把不同專案類型、不同路徑、不同應用方式收攏到一起。 這當然沒錯。但它更深一層的意義，不只是「更方便」，而是去碎片化。

過去產業裡並不是沒有人談健康。 相反，大家都在談。開發商談資產價值，設計師談空間體驗，工程端談系統性能，品牌商談產品參數，顧問談條文與路徑，而最終使用者在意的，卻是睡眠、專注、舒適、恢復與長期狀態。

問題不在於誰錯。 問題在於：這些語言常常彼此接不上。於是市場上就會出現一個很常見的現象： 大家都在說健康， 但健康始終沒有真正變成一套統一的行動邏輯。

而 One WELL 的重要意義，就是試圖把這些分散的表達，重新拉回一個更統一的結構中。

所以它不只是整合文本， 更是在整合語言。

四、One WELL 不是只在統一名稱

而是在統一邏輯、統一呈現、統一理解方式

從目前公開階段能看到的方向中，One WELL 很強調幾個關鍵詞: Harmonized, Clarified, Evergreen, and Smarter.

如果用更容易理解的話來說，大致就是四件事：

首先， 更統一。也就是盡可能減少不同路徑、不同模組之間那種「名字很像、邏輯不同」的摩擦。

其次， 更清晰。不是單純增加內容，而是讓策略寫法、適用性表達、閱讀方式更容易理解與實施。

再來， 更持續更新。不是每隔幾年做一次劇烈重構，而是透過持續增強、逐步優化的方式演進。

第四， 更像平台。不僅是發布標準，還要讓數位介面、比較機制、變更記錄、進度追蹤等功能，真正支持使用者在實施過程中管理複雜性。

這說明 One WELL 的目標，不只是讓專業人士更方便看標準， 而是讓 WELL 更適合被團隊、組織和多專案體系持續使用。

五、One WELL 更深的意義，不是整合標準

而是讓 WELL 更像一個平台

這是我認為最值得產業重視的地方。 過去很多人理解標準，還停留在很傳統的想像裡：標準，就是一本書；一套條文；一張 checklist；一套認證要求。

但真正有影響力的標準，從來不只是文件。 它同時也是一種組織市場的方式。

從目前 One WELL 公開預覽中能看到的方向看，IWBI 顯然不只是想讓 WELL 更完整，它還想讓 WELL 更具備這些特徵：

• 更容易被比較與追蹤；
• 更容易被組織層面管理；
• 更容易支持多地點、多專案組合；
• 更容易隨著更新持續演進；
• 更容易讓使用者看到進展、變化與累積成果。

當這些特徵逐漸強化時，WELL 的角色就不再只是認證體系，而越來越像一個平台型系統。

所以我才會說： One WELL 的意義，不只是把 WELL「合成一個版本」， 而是在把 WELL 重構成一個更統一、更動態、更可管理的平台型標準體系。

六、這會直接改變產業的價值排序

當健康開始透過更統一的語言、更一致的結構、更持續的更新機制來表達時，產業的價值邏輯也會跟著變化。

過去很多企業競爭的是：誰的產品參數更漂亮；誰的設計更好看；誰更懂認證路徑；誰更會講健康概念。

但未來，真正重要的問題會越來越變成： 你能不能把「健康」這件事，更穩定、更清楚、更可驗證地交付出來。

這意味著市場會逐步從： 賣產品，走向賣結果；做一次性交付，走向持續追蹤；講概念，走向講實施能力；講設計意圖，走向講組織層面的健康策略與績效。

對企業來說，這不是修辭變化。這是競爭邏輯的變化。

七、對照明行業來說，這個信號尤其直接

為什麼我特別強調照明行業？因為照明行業過去太容易把複雜問題說簡單。

照度、色溫、顯指、節能、控制、場景，這些當然都重要。但這些從來不自動等於「健康光」。

真正與人有關的光，一定同時涉及：人是誰；空間是什麼；在什麼時間；做什麼活動；暴露多久； 目標是什麼；最後結果如何驗證。

而在 One WELL 這樣更統一、更強調實施與持續優化的邏輯下，光不會再只是某個 concept 下的一組條文，而會越來越被放到更清楚的戰略目標、組織邏輯與結果導向中去理解。

這對照明行業是一個很明確的提醒： 未來競爭，不只是講燈具，也不只是講參數，而是要開始講：

你的光，如何在一個更完整的人、空間、時間與策略框架中，真正創造可衡量的價值。

這對真正有系統能力的企業，是機會。 但對只停留在產品包裝與概念營銷層面的企業，會越來越有壓力。

八、One WELL 還釋放出一個重要信號：標準正在從「版本制」走向「持續增強制」 From Version-Based Thinking to Continuous Enhancement

這也是這次公開階段很值得注意的一點。 One WELL 不是在傳遞「某一天上線一個最終版本，然後多年不動」的感覺，而更像是在建立一種持續增強、漸進演進的邏輯。

這種邏輯意味著：標準不只是發布，還要持續吸收回饋；不只是定稿，還要持續優化；不只是審查專案，還要幫助組織更有效地管理進展。

也正因如此，One WELL 的公開徵詢階段才特別重要。 它不是一個形式性的流程，而是在為後續的平台化演進建立市場輸入機制。所以對行業來說，現在最值得做的，不是急著下結論，而是認真看方向、提意見、參與討論。

九、因此，現階段討論 One WELL，最需要的是分寸感

我覺得這點很重要。因為 One WELL 目前處於公開預覽與 public comment 階段。這意味著行業當然可以討論它的方向、意義與潛在影響，但也應該尊重這個階段的邊界：

可以談公開資訊釋放出來的制度邏輯；可以談對產業與企業意味著什麼；可以提出專業回饋與建議；但不宜把尚未最終確定的內容寫成既定事實，更不宜把內部交流語境，直接當作對外定稿表達。

這既是專業態度，也是對 IWBI 機制本身的尊重。

十、結語：One WELL，不只是把 WELL 做大

而是在把「健康」變成一種更可部署的秩序 “Health” Into a More Deployable Order

所以回到最初的問題： One WELL 對產業意味著什麼？

它意味著，健康建築產業開始從碎片化走向系統化，從多方各說各話，走向更統一的語言與邏輯， 從靜態標準，走向更動態的平台型體系。

One WELL 對 IWBI 又意味著什麼？

它意味著，IWBI 正在從標準發布者，進一步走向平台組織者；從單純認證體系的擁有者，走向健康建築生態語言和實施邏輯的塑造者。

而對照明行業來說，這個信號尤其明確：未來的競爭，不再只是看誰能把空間照亮；而是看誰能真正證明—— 光，如何在一個更完整的人本框架裡，改善人的狀態。

這，才是 One WELL 真正值得重視的地方。

文末說明

本文基於作者參加 2026 IWBI 全球顧問啟動會議後的個人觀察，並結合目前已進入公開預覽 / public comment 階段的 One WELL 相關公開資訊所作之思考。本文不構成對 IWBI 最終標準文本的官方解讀，具體內容仍應以 IWBI 後續正式發布版本為準。

當我們談病態建築，為什麼總是忘了「光」？

人類現代建築史，某種程度上，也是一部人類馴服黑夜的歷史。

從愛迪生將白熾燈推向量產開始，光第一次真正脫離了火焰、脫離了日落，成為可被控制、可被部署、可被複製的基礎設施。

那一刻起，建築不再只是遮風避雨的殼體，而開始擁有了延展時間、塑造行為、重組生活節奏的能力。

光，讓空間從白天的附屬品，變成二十四小時運轉的人類場域。

而後，建築大師柯比意說，光是空間的第四維度。
這句話之所以偉大，不只是因為它浪漫，而是因為它準確。

因為真正塑造空間感知的，從來不只是牆、地、頂三個維度，還有光如何進入、停留、轉折、消失。

沒有光，空間只是體積。
有了光，空間才有了層次、方向、情緒、秩序，甚至靈魂。

所以很長一段時間裡，建築與照明共同追求的，是一件本來很了不起的事： 不只是照亮空間，而是照靚空間。

光讓建築更可見，讓材料更有質感，讓秩序更清晰，讓城市的夜晚有了表情。 光曾經是文明的延伸，也是建築最有力量、最有溫度的語言之一。

但今天，我們似乎走到了一個值得警惕的岔路口。

當節能成為唯一正確，建築開始慢慢忘記自己是為誰存在

近十多年，節能成了建築領域幾乎不可挑戰的政治正確。

節能當然重要，減碳也當然必要。
問題不在於節能本身，而在於我們是否在不知不覺中，把手段當成了目的。

因此：

• 於是，照明功率密度一再被壓縮。
• 於是，白天的室內被設計得越來越暗，彷彿只要滿足最低標準，建築就算完成了責任。
• 於是，夜晚的城市卻越來越亮，招牌、立面、景觀、屏幕彼此競逐，讓黑夜失去了作為黑夜的權利。

這是一個荒謬但真實的時代切面：

• 我們在白天，給人不夠的光；
• 在夜晚，卻給人過量的光

白天本該提供清晰、充足、能支持覺醒與專注的環境；
夜晚本該收斂、降躁、保留黑暗，讓人的生理節律能夠回到平衡。

但今天大量建築剛好相反。

• 辦公室裡，人們在白天精神渙散、眼睛疲勞、情緒低沉；
• 酒店裡，住客明明想休息，卻被錯誤的色溫、眩光與光洩漏打擾；
• 醫院裡，病人與醫護長時間暴露在不對時、不對量、不對方向的光環境裡；
• 住宅裡，孩子白天不見天日，晚上卻被螢幕和高刺激照明包圍。

這不是技術不夠。
恰恰相反，這是因為我們太久以來，把光只當成了:

• 設備問題
• 能耗問題
• 裝飾問題

卻沒有把它當成人的問題、時間的問題、健康的問題。

---

病態建築，不該只談空氣，卻對光失語

今天當我們談到 Sick Building Syndrome（病態建築症候群），大家很自然會想到:

• 空氣品質
• VOC
• 通風不足
• 濕度控制
• 黴菌
• 過濾系統

這些都很重要。但奇怪的是，光常常被邊緣化。 彷彿只要空氣好了，建築就健康了。

事實上，一棟真正讓人疲憊、失眠、焦躁、頭痛、效率低落、情緒失衡的建築，往往不只是空氣出了問題。它同時也可能存在：

• 不足或錯誤時段的光暴露
• 不合理的眩光與高亮對比
• 白天垂直照度不足
• 夜晚刺激過高
• 熱舒適失衡
• 噪音持續干擾
• 空間節奏與人的活動模式錯位

也就是說，病態建築從來不是單因子的結果，而是多環境因子共同失調的綜合症。

如果我們今天承認空氣會讓人生病，為什麼不承認光也會？
如果我們承認噪音會造成壓力，為什麼不承認錯誤的光會破壞睡眠與節律？
如果我們承認熱舒適影響生理負荷，為什麼不承認光同樣在調節人的警覺、情緒、荷爾蒙與行為？

建築若以服務人為目的，就不能只在一個指標上表現優秀，卻在另一個更基礎的維度上持續失分。

---

我們需要的，不是更多燈，而是重新理解光的角色

問題的根本，不在於要不要多裝幾盞燈，也不在於把照度表上的數字再拉高一點。

真正需要被重建的，是我們對光的理解框架。

因為光從來不是孤立存在的。它總是與以下幾件事交織在一起：

• 人 — 這是誰？年齡、作息、敏感度、健康狀態、任務需求是否不同？
• 空間 — 這是哪裡？辦公、學習、醫療、住宅、交通、商業、酒店，其目的完全不同。
• 時間 — 是清晨、白天、傍晚、夜間，還是跨時區與輪班情境？
• 活動 — 人在這裡是專注、休息、社交、療養、康復、轉換，還是沉思？

所以光的設計，不應再停留在:

• 「夠不夠亮」
• 「好不好看」
• 「省不省電」三個問題。

而應該進一步問：

這個空間，在這個時間，為這群人，支持的是什麼活動？
它提供的光，究竟是在幫助人，還是在消耗人？

這才是未來建築與照明真正應該回答的命題。

---

建築的目的，從來不是節能本身，而是用更好的方式服務人

這句話可能需要被重新說一次：建築的目的，從來不是節能。

節能很重要，但節能不是建築存在的本體目的。

建築的本質，是提供:

• 庇護
• 秩序
• 效率
• 尊嚴
• 健康
• 交流
• 康復
• 休息
• 與生活的可能

如果一棟建築極度節能，卻讓人昏沉、焦躁、失眠、低效，那它在能耗帳本上也許是成功的， 但在人的尺度上，可能是失敗的。

我們不能用節能的語言，把人的需求擠壓成附屬條件。
更不能讓功率密度、最低標準、設備參數，取代了對人的真實關懷。

真正高水平的建築，應該是能在能源、環境與人之間建立更高級的平衡。

不是回到粗放浪費的年代，而是進入一個更精準、更懂人、更講究時間與場景的時代。

---

從「照明設計」走向「人的環境編排」

未來的建築與光，也許需要的不再只是傳統意義上的照明設計，而是一種更整體的環境編排能力。

這種能力要求我們同時思考：

• 白天如何讓人真正清醒、專注、舒適
• 夜晚如何讓空間降低刺激、保留休息的可能
• 光如何與自然採光、遮陽、材料反射、熱環境、聲環境協同
• 如何依照不同人群與活動節奏動態調整
• 如何用測量與驗證，而不是只用想像與效果圖判斷成果

換句話說，未來不是

「燈具放哪裡」而已，

而是

「這個環境如何在一天之中，真正服務人的身心節律與活動品質」

這裡面，光不再只是裝修完成前的最後一道工序。
它應該回到建築一開始就被思考的位置。

不是附屬，而是核心。
不是配角，而是基礎設施。

---

是時候，把光重新放回建築的中心

我們這一代，或許正站在一個重要轉折點上。

前一個時代，讓我們學會如何有效地用光。
下一個時代，則要求我們學會如何正確地用光。

前一個時代，建築追求的是可見。
下一個時代，建築更應追求:

• 可感
• 可用
• 可恢復
• 可長久相處

當我們重新審視病態建築，重新審視節能與健康之間的張力，也許最該被重問的，不是:

「還能再省多少電」

而是

• 這棟建築，是否真正理解人？
• 它給人的光，是否符合人的時間、生理與活動需求？
• 它是否在白天支持生命，在夜晚尊重黑暗？

因為說到底

建築不是為了證明自己有多節能而存在，
而是為了讓人在其中活得更好。

而光，從來不只是把空間照亮。它更應該把人，重新帶回建築的中心。

摘要

當整個行業都在談健康照明、節律照明與human centric lighting，LED 燈珠企業若還只會在規格書裡寫光效、顯指、色容差與價格，恐怕已經落後半個時代。

CIE S 026 帶來的，不是多一個新名詞，而是要求上游元器件企業重新建立一套能描述「光如何作用於人」的規格語言。

真正關鍵的，不只是melanopic，而是五類α-opic DER 與EDI 的完整框架；真正決定下一輪定價權的，也不是誰喊得最大聲，而是誰先把這套能力寫進datasheet、做進toolbox、接進應用鏈。

這兩年，我越來越強烈地感受到一件事：很多LED 企業，嘴上在談健康照明，手上的規格書卻還停留在上一個時代。

還在比什麼？

• 比光效
• 比顯指
• R9
• 比SDCM
• 比價格

再進步一點，開始談TM-30、談低頻閃、談光品質。 這些都對。 但還不夠。

因為如果今天整個行業都在說：光不只是讓人看見，還會影響節律、警覺、情緒、睡眠、恢復，甚至長期健康；那麼請問—— 為什麼到了LED 最上游的燈珠規格書，很多企業還在用一套幾乎完全「看不見人」的語言？

這才是問題的核心。

不是CIE S 026 重不重要。不是melanopic、α-opic 難不難。 而是：如果上游元器件企業自己都還沒有能力，將「光如何作用於人」這件事，翻譯成可交付、可運算、可比較、可設計的datasheet 語言，那整個健康光產業，大半都還只是口號。

這句話可能有點重。但我認為，現在是時候講重一點了。

---

1. 很多企業誤會了：CIE S 026 不是市場部多一個賣點

現在不少企業開始知道melanopic EDI，開始在簡報裡加上α-opic，甚至有人已經想把這些詞直接寫進燈珠規格書。 方向沒錯。 但很多寫法，一看就知道還沒有真正理解CIE S 026。

最大的誤區是什麼？就是把它當成另一個可以拿來包裝高端的參數。這很危險。

因為CIE S 026 不是一個新的marketing badge，也不是一張能貼在包裝盒上的認證標籤。 它本質上是一套視網膜光受體加權的計量語言，是把「光對人」的描述，從模糊的概念，推向可以被精確計算的框架。

而一旦你真把它看成計量語言，你就會立刻意識到一件事：這不是在規格書上多加一個melanopic 數字那麼簡單。

這是在逼著LED 上游企業，重新回答一個問題：你賣的，到底只是一顆會發光的半導體元件，還是一個可被生理模型調用的光譜引擎？

這兩者，差很多。

---

2. 先把最根本的錯誤糾正：EDI 不是只有melanopic 一個

我最近注意到，連不少業內人士都還停留在一個模糊認知裡：以為DER 是五類α-opic 指標，但EDI 好像主要就是melanopic EDI。這個理解，實務上常見，但技術上並不完整。

如果回到CIE S 026 的原始邏輯，事情其實很清楚： 不只是DER 有五類，EDI 本身也同樣有五類。

也就是說，對應五類視網膜光感受器通道：

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

理論上都各自有：

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

換句話說，EDI 不是一個值，而是一組值。

只是因為近年在晝夜節律、WELL、白天提神與夜晚抑制等應用溝通中，melanopic EDI 被最頻繁單獨拿出來用，久而久之，市場就誤以為EDI 差不多就是melanopic EDI。

這個誤會，看起來只是術語問題。但如果放到燈珠企業的規格書邏輯裡，它會直接導致整個datasheet 寫偏。因為你一旦把EDI 簡化成單一melanopic 指標，你其實已經默默把CIE S 026 的完整五維框架，壓縮成一條單線敘事。

而這，恰恰是我最不希望看到的事。

---

3. LED 行業最怕的，不是複雜；最怕的是「假裝簡單」

我一直認為，LED 行業最大的能力之一，是把複雜問題工程化。當年LED 替代傳統照明，也不是因為LED 本身不複雜。恰恰相反，是因為它太複雜。

它有電特性。 有熱特性。 有光衰。 有色漂。 有binning。有封裝差異。有驅動耦合。有系統效率。 有壽命模型。有可靠性風險。

但後來整個行業之所以成熟，是因為大家逐步建立了一套共同語言，把這些複雜性，轉化為客戶能用、工程師能算、FAE 能解釋、設計師能調用的規格與工具。

這才是LED 產業真正了不起的地方。

所以今天如果α-opic、EDI、DER 進入元器件體系，我的態度很明確：不要怕複雜。怕的是把原本五維的東西，偷懶寫成一個單值，然後拿去做宣傳。

那不是簡化。那是降智。

因為一旦上游把多維光生理問題簡化成一個「高melanopic 就比較先進」的敘事，後面就一定會出現兩種結果：

1. 市場部會過度包裝。
2. 應用端會錯誤使用。

最後受傷的，不只是企業自己，還包括整個健康照明領域的公信力。

---

4. 對燈珠製造商來說，DER 跟EDI 的角色根本不同

這裡我想講得更直接一點：如果你是LED 燈珠企業，真正應該優先寫進主規格表的，是五類α-opic DER；而EDI，應該作為條件化、歸一化的結果量來呈現。

為什麼？

因為DER 更接近什麼？更接近這顆LED 光譜本身的屬性。

只要SPD 定了，DER 基本上就跟著定了。它是源級光譜特徵。

那EDI 呢？EDI 不是脫離條件的絕對常數。它是建立在某個photopic illuminance 基礎上的等效daylight illuminance 表達。

講白一點：DER 比較像原材料特性；EDI 比較像在某個使用條件下的換算結果。

這就像你不能把某顆LED 的某距離下中心照度，當成燈珠固有屬性一樣。
同理，你也不應該把一個沒有寫明前提條件的EDI，包裝成燈珠自身的絕對能力。

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

但沒說明這是：

• 對應多少photopic illuminance
• 基於什麼SPD 分辨率
• 在什麼If / Tj 下測得
• 是否為歸一化條件
• 是否只是source-level 換算值

那這個數字，嚴格說，技術含量是可疑的。

不是因為EDI 不能寫。而是因為不帶條件寫EDI，本身就是一種不完整。

---

5. 上游企業現在真正缺的，不是一個新參數，而是第五套模型

我想把這件事說得更系統一點。今天成熟的LED 企業，基本上都已經建立了四套模型：

第一套，電模型
If、Vf、功耗、驅動範圍、調光特性。

第二套，熱模型
Tc、Tj、熱阻、降額曲線、熱失效風險、壽命邊界。

第三套，光模型
光通量、CCT、色坐標、bin、顯色、TM-30、色漂、光譜。

第四套，可靠性模型
LM-80、維持率、封裝穩定性、失效率、環境適應性。

但是到了今天，如果還要真正往「健康光」「節律光」「高品質光譜價值鏈」走下去，企業就必須補上第五套：

第五套模型：生理光譜模型

這才是CIE S 026 真正對LED 上游提出的要求。不是叫你在PPT 上加一頁α-opic。而是叫你開始建立這樣的能力：

• 五類α-opic DER
• 五類α-opic EDI
• 它們與SPD 的對應關係
• 它們與電流、結溫、老化、binning 的關聯
• 它們如何進入混光、調光、場景算法與下游應用設計

這才是懂CIE S 026 的企業。而不是只會說一句「我們的產品支持健康照明」。

---

6. 真正厲害的燈珠企業，規格書會這樣寫

我講一個很務實的判斷標準。未來你看一家LED 燈珠企業是不是走在前面，不要先看他簡報裡有沒有human centric lighting。

先看他規格書怎麼寫。我認為，一家真正往前走的企業，至少會分三層來做。

第一層：主表先把五類 α-opic DER 建起來

這是最核心的基本盤。不是只寫melanopic。
而是逐步把：

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

建立成標準輸出。因為這才是對CIE S 026 最基本的尊重。你不能嘴上說自己在做α-opic，結果最後只拿一條最方便賣的數字出來。

第二層：EDI 可以寫，但必須是「有條件的EDI」

例如：

• Melanopic EDI @ 100 lx
• Melanopic EDI @ 300 lx
• 甚至五類α-opic EDI @ 100 lx / 300 lx / 500 lx

這種寫法就合理得多。因為它承認EDI 是基於photopic illuminance 換算出的結果，而不是把它假裝成一個脫離條件的絕對值。

第三層：把 α-opic 與電熱漂移、老化、binning 打通

這一步才真正拉開差距。因為如果你的α-opic 數值不會隨If、Tj、aging 改變，那只有兩種可能：

• 要嘛你產品神到違反物理，
• 要嘛你根本還沒真的開始建模。

所以，未來更高水平的datasheet 應該開始出現：

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

到這一步，α-opic 才真正從概念變成可交付能力。

---

7. 今天最值得警惕的，是「melanopic 單一崇拜」

我其實很能理解，為什麼市場上會快速聚焦melanopic。 因為它最容易講。 也最容易跟日間提神、夜間抑制、WELL、晝夜節律等應用連上。

但我要很坦白地說：如果整個產業最後把CIE S 026 收斂成「誰的melanopic 比較高」這種單一競賽，那我們只是把過去拼lm/W 的老路，換了一個更時髦的詞重演一次。

這不是產業升級。這只是口號升級。因為真正的光環境，從來不是只看單一通道。 真正的人的反應，也從來不是只靠一個值就能概括。

所以我非常主張一件事：在傳播上，可以先從melanopic 切入；但在技術底層，一定要回到五類α-opic 的完整框架。

否則後面一定會出現一堆「高melanopic 但整體光品質很差」的產品，或者一堆「拿單一值過度承諾生理效果」的市場話術。

那不是我期待的未來。

---

8. 這不是技術細節，而是上游企業下一輪定價權

很多人會把這篇文章看成技術話題。 我不這麼看。 我認為這其實是產業話語權的問題。

過去十多年，LED 行業上游能掌握價值，靠的是什麼？ 不是因為誰最會講故事。 而是因為誰掌握：

• 更好的封裝能力
• 更穩定的binning
• 更成熟的可靠性模型
• 更完整的應用支持
• 更高效的規格語言

今天到了CIE S 026 時代，這套遊戲並沒有變。只是競爭維度升級了。

未來真正高價值的燈珠企業，不只是能說「我們有某某波段、某某配方、某某顯色」。 而是能說： 我們這顆LED，不只光效高、顏色準、可靠性穩； 它的五類α-opic 特徵是可定義的、可重複的、可運算的、可進入系統設計的。

一旦做到這一步，你賣的就不只是燈珠。 你賣的是：可被下游直接調用的光譜能力。而這，才是真正能撐起下一輪溢價的東西。

---

9. 別急著喊「健康照明」，先把規格書寫對

如果讓我給LED 燈珠製造商一個最直接的建議，我會說：別急著在展台上喊自己懂健康光。先回去看看你的datasheet。

如果你的規格書還只能描述：

• 多亮
• 多省
• 多白
• 多高顯色
• 多低色差

卻還不能描述：

• 這顆LED 的五類α-opic 特徵是什麼
• DER 與EDI 如何定義
• 與電流、結溫、老化如何耦合
• 下游客戶如何把它接進場景與人的模型

那麼你離真正的「健康光元器件企業」，恐怕還有一段距離。不是因為你技術不夠。 而是因為你的產業語言，還沒升級。

而我相信，下一輪真正有機會拿到話語權的，不是最早喊口號的人，
而是最早把這套語言——寫進規格書、做進toolbox、接進應用鏈、變成交付能力的人。

這才是CIE S 026 對LED 上游真正的意義。 不是多印幾個參數。而是重寫規則。

---

Conclusion

未來客戶買的，不只是流明。
他們買的，是一顆LED 能否被準確放進「人」的模型裡。

這些年，照明行業越來越喜歡談幾個詞： 健康照明、人因照明、晝夜節律、低頻閃、高顯指、智慧控制。

聽起來都對。但很多時候，問題也恰恰出在這裡。

因為太多人以為，只要把幾個「正確參數」拼在一起，就等於做出了「更健康的光」。

於是行業裡出現了大量看似先進、實則片段化的表達：

把高顯指當成健康光，把可調色溫當成節律光，把低頻閃當成高品質，把智慧系統當成最終答案。

但如果認真看 WELL，尤其是今天再回頭看 WELL v2 的 Light 概念，你會發現它要說的，其實遠不止這些。

WELL光概念，不是9個條款。

它真正試圖推動的，是照明行業從「賣燈、賣參數、賣控制」這套舊邏輯，轉向「交付對人真正有效的光環境」這套新邏輯。

我而言，這不是一次普通的標準更新。 這更像是一面鏡子，逼著整個行業重新回答一個根本問題：

我們到底是在做照明，還是在做與人有關的光？

---

1. WELL為什麼值得今天重新認真讀一遍？

我一直認為，WELL 對照明行業最重要的地方，不是它是不是一套認證標準。

而是它逼著這個行業重新面對一個根本問題：

我們到底是在賣照明設備，還是在交付人的光環境體驗與健康結果？

這是兩個完全不同的生意。

前者的邏輯，是拚價格、拚效率、拚外觀、拚交期、拚協議。

後者的邏輯，是拚理解人、理解空間、理解時間、理解測量、理解控制、理解長期表現。

過去行業裡很多所謂「健康照明」的討論，之所以走不深，不是因為大家不努力，而是因為大家還在用舊時代的方法，處理一個新時代的問題。

用過去「燈具導向」的思維，去做今天「人導向」的課題，當然會不夠。

而 WELL 的價值，就在於它不是停留在一句「健康很重要」的道德判斷上。

它試圖把這件事拆成一套真實可執行的系統語言：

• 你怎麼設計?
• 怎麼選型?
• 怎麼證明?
• 怎麼測試?
• 怎麼運行?

所以，今天重看 WELL，不是因為它「流行」。 而是因為它正在越來越接近行業未來真正需要的底層能力。

---

2. WELL光概念，表面是9個條款，底層是一整套方法論

很多人第一次看 WELL Light，會把它理解成一組 feature 清單。 L01 到 L09，逐條對照，逐條滿足。

這樣看當然沒錯。但如果只看到這裡，其實只看到了表層。

因為 WELL 光概念真正厲害的地方，不在於它列出了9個條款，而在於這9個條款背後，已經隱含了一套完整的方法論：

光接觸 →視覺可見 →節律支持 →眩光控制 →日光協同 →視覺平衡 →電氣品質 →使用者控制

這不是簡單的 checklist。這是一整套關於「什麼才叫好光環境」的結構化回答。

What should good light really do for people in space?

說得更直白一點：

過去行業思維常常是，燈具選好了，照度夠了，控制有了，這事就差不多了。

但 WELL 的邏輯不是這樣。它在追問的是：

• 這個空間裡的人，有沒有獲得足夠且合適的光接觸？

• 這個光是不是支持視覺任務，而不是製造疲勞？

• 這個光會不會支持白天清醒，卻破壞夜晚休息？

• 這個光會不會造成眩光？

• 這個空間有沒有把日光用好？

• 光環境是否平衡，而不是忽明忽暗、冷熱混亂？

• 燈具品質是否足夠，顯色和頻閃是否過關？

• 使用者能不能真正掌控自己的光環境？

當一套標準開始用這樣的方式提問時，它其實已經不再只是在定義「照明」，它是在定義「人與空間之間的光關係」。

---

3. 這場重構，第一刀砍向的就是「參數崇拜」

我認為，WELL 對照明行業最深的一刀，就是它在動搖行業長期以來最習慣的那種參數崇拜。

過去大家太容易相信一件事：只要我有幾個好參數，我就是好產品；只要我能講出幾個先進概念，我就是好方案。

但 WELL 給出的答案是： 不夠。

舉個最簡單的例子。一個項目可以有不錯的 CRI，也可以有可調色溫，甚至還可以做出某種節律照明敘事。但如果這個空間眩光很強、亮度分布失衡、頻閃控制不佳、使用者無法調節、夜晚策略混亂，那它依然不是一個真正高品質的光環境。

這件事聽起來像常識，但行業裡真正做到的人並不多。因為參數是最容易行銷的。而系統能力，是最難行銷、也最難偽裝的。

參數可以截圖。系統能力要靠項目結果說話。 參數可以在展會海報上放大。系統能力要穿過設計、施工、調試、驗證和運營的全過程。

所以從這個角度看，WELL 真正重構的，不只是技術語言，更是行業的價值判斷標準。

---

4. 為什麼我說它不是條款，而是價值重構？

因為它重新定義了

「誰更有價值」

在舊邏輯裡，最有價值的人，通常是最會做產品的人。或者說，是最會把產品賣出去的人。 但在 WELL 邏輯下，真正有價值的人，會逐漸變成下面這幾類：

第一類，真正理解人的人。

不是只會看參數，而是理解光如何影響視覺、情緒、清醒度、疲勞感與作息體驗。

第二類，真正理解空間的人。

知道光不是抽象存在，而總是發生在建築、立面、朝向、材料、任務和行為之中。

第三類，真正理解時間的人。

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

第四類，真正理解驗證的人。

知道今天的照明項目，已經不能只靠設計表達，而必須靠技術文件、模擬、測試與可追溯證據來完成交付。

第五類，真正理解運營的人。

因為再好的光，如果離開調試、維護和使用場景，很快就會從「設計效果」變成「現實妥協」。

這就是為什麼我說，WELL 光概念表面看是 feature，本質上卻是在改寫行業裡「誰值得被高估」的標準。

---

5. 對照明公司來說，最該升級的不是行銷，而是證據鏈

很多照明公司現在已經會講 WELL 了。 但我坦白說，大多數還是停留在「會講」階段。

真正的問題是： 你到底是在支持 WELL，還是在借 WELL 說故事？

如果真的要進入 WELL 項目邏輯，照明公司最該升級的，不是宣傳頁，而是證據鏈。

你不能只說「我們高顯指」。 你要能說明，在不同色溫、不同調光狀態下，顯色是否依然成立。

你不能只說「我們低頻閃」。 你要能提供清晰的測試依據與適用條件。

你不能只說「我們支持眩光控制」。 你要能證明你的數據與真實空間設計條件相匹配。

你不能只說「我們可以做智慧控制」。 你要能說明控制分區、場景邏輯、使用者介面、相容性以及最終可用性。

未來真正有競爭力的廠家，不是那個 PPT 做得最好看的，

而是那個最能幫項目團隊降低不確定性、提高落地率的。

換句話說，客戶買的不是燈。客戶買的是： 你能不能讓項目更穩地被設計出來、被證明成立、被測試通過，並在後期繼續運行得像樣。

---

6. 對設計師來說，真正的分水嶺來了

過去做照明設計，很多時候核心是「布燈」。 再往前一步，是「做氛圍」。 再進一步，是「做場景控制」。

但現在，如果你真的要面對 WELL，或者更廣泛地面對健康光環境趨勢，設計師的分水嶺已經不在這些層次上了。

真正的分水嶺是： 你做的是燈具配置，還是光環境建構？

這兩個概念差別非常大。燈具配置，是把產品放進空間。

光環境建構，是把人的行為、視線、任務、時段、節律與空間結構一起納入判斷。

所以今天真正優秀的設計師，不能只會算平均照度。

還要會看：

• 人在不同姿態下接收到什麼光
• 視平線附近的亮度與對比是否舒服
• 白天的日光是否被合理利用
• 夜晚的刺激是否被有效壓低
• 相鄰區域是否失衡
• 色溫、顯色與控制邏輯是否一致
• 場景是否真實可用，而不是為了匯報好看

說得再直一點： 未來不會缺「會做燈光效果圖」的設計師。

未來真正稀缺的，是能把健康主張做成空間結果的設計師。

7. 經銷商和渠道商，也不能再只是搬貨了

這一點很多人容易忽略。但我認為，WELL 對經銷商的影響其實非常大。

因為當項目越來越複雜，客戶真正需要的就不再只是「哪個品牌有貨、哪個型號便宜」。

客戶需要的是有人告訴他：這幾個條款裡

• 哪些是產品直接支持的?
• 哪些是設計層面解決的?
• 哪些需要控制系統配合?
• 哪些需要現場測試才能閉環?

這時候，經銷商如果還是只會背價格單、背折扣、背交期，價值會越來越薄。

反過來，誰能整合產品資料、控制能力、應用經驗與項目理解，誰的角色就會從「供貨渠道」變成「項目協同者」。

這就是價值重構在渠道端的真實表現。

---

8. One WELL 正在釋放一個越來越清楚的信號

很多人關心的是：下一版會不會改參數？會不會調門檻？會不會新增條文？

這些當然重要。但在我看來，更重要的是它釋放出來的總方向。

這個方向其實越來越明確： WELL 正在持續把「健康」從一個善意理念，推進成一個更清晰、更精確、更可實施的行業框架。

這對照明行業意味著什麼？意味著以後越來越難靠模糊表達混過去。

越來越多事情都要被問清楚：

• 你的設計依據是什麼？
• 你的參數適用於什麼條件？
• 你的產品如何支持真實空間？
• 你的控制策略是否真的可用？
• 你的現場測試怎麼完成？
• 你的後期運營如何維持效果？

這對行業當然是壓力。但我認為，這也是好事。

因為一個行業真正成熟，不是靠所有人都把故事講得越來越大，而是靠所有人都更願意面對證據、面對邊界、面對真實交付。

---

9. 最後，WELL真正重構的是行業的自我認知’s self-understanding

寫到這裡，我其實最想說的一句話是： WELL光概念，真正改變的，不只是項目做法，而是行業怎麼看自己。

如果我們還把自己看成「照明產品行業」， 那未來無非就是繼續卷效率、卷價格、卷功能堆疊。

但如果我們開始把自己看成「光環境能力行業」， 那一切都會不一樣。

我們會更認真地看待：

• 光與睡眠的關係
• 光與認知表現的關係
• 光與情緒的關係
• 光與空間運營的關係
• 光與長期健康體驗的關係

那時，燈具依然重要。控制依然重要。 系統依然重要。

但它們都不再是終點。它們只是手段。

真正的終點，是： 讓光更好地服務於人。

而 WELL v2 的 Light 概念，連同正在推進中的 One WELL，真正想推動的，正是這件事。

所以我才會說： WELL光概念，不是9個條款。 而是一場照明行業的價值重構。

⸻

Closing lines

過去，我們習慣問：這盞燈夠不夠亮？夠不夠省？夠不夠智慧？

未來，我們更應該問： 這束光，是否真的對人更好？

當這個問題成為行業共識的那一天，照明行業才算真正進入了下一階段。

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，其實隱藏著一個不尋常的信號。

Lighting Recipe Studio × Traxon Technologies Limited

如果你只是把它看成：一次企業之間的合作

那你可能錯過了真正重要的訊號。

---

一、照明產業，其實已經換了一套邏輯

過去十年，照明產業其實走了兩條不同的路。

一條路，專注於打造「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？

因為整個產業，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照明控制系統。

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，照明產業比的是：

• 誰更亮
• 誰更省電

未來，照明產業比的是：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，照明產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，但照明產業，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.

LRS Editorial / Lawrence Lin
Lighting Recipe Studio

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.

換句話說：

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” to “light exposure management”
• From “parameter stacking” to “structural models”
• From “emotional narratives” to “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）
• 相關色溫 (CCT)
• 顯色指數（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

的 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

的 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.

Note:

• 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
• 願景
• 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.
