Letter to Lighting Design Tool Manufacturers: If You Don\u2019t Embrace Human-Centric Lighting (HCL), You\u2019re Leaving Designers in the Past\u201d -","og_description":"Over the past twenty years, lighting design software has done something extremely important for the industry\u2014it has transformed illuminance calculations, light distribution simulations, glare control, and energy consumption estimates into a visual workflow. But now, the demand has quietly shifted: Clients no longer ask only, \u201cIs it bright enough? Is it energy-efficient?\u201d Increasingly, they are asking: \u201cDoes this lighting support sleep, vision, focus, and mood?\u201d As healthy lighting \/ HCL \/ human-centric lighting moves from academic papers into tender documents, certification standards, and client KPIs, design tools that still only calculate Eh, UGR, and installed power are effectively keeping every designer using your software stuck in the previous generation\u2019s rules of the game. This article aims to have a serious conversation with lighting tool manufacturers about three things: 1. Real-World Project KPIs Have Changed: From \u201cIlluminance Compliance\u201d to \u201cHealth and Performance\u201d Today\u2019s clients\u2014especially hospitals, schools, corporate headquarters, luxury residences, and hotels\u2014are increasingly accustomed to incorporating \u201chealth\u201d into project goals: These goals cannot be addressed solely with horizontal illuminance (Eh), UGR, or power density (W\/m\u00b2). Clients care about: Yet, most mainstream design tools today still operate with a workflow like: \u201cSelect fixtures \u2192 Place fixtures \u2192 Calculate Eh\/UGR \u2192 Check false color \u2192 Export report.\u201d While this remains important, it is no longer sufficient. 2. If Design Software Only Calculates Horizontal Illuminance, Supporting HCL Becomes Very Difficult From a healthy lighting \/ HCL perspective, current design tools have several structural gaps: 1. Lack of \u201cHuman Eye Perspective\u201d and Vertical \/ Circadian Metrics Result: Designers may create a \u201ccompliant\u201d plan in software, but on-site measurements with tools like In.Licht Ultra often reveal that eye-level Ev or circadian stimulation is severely insufficient or excessive. 2. Lack of a \u201cTimeline\u201d Concept Currently, most tools still work like this: Calculate illuminance for one \u201ctypical scenario,\u201d maybe add a second \u201cenergy-saving mode.\u201d Without a timeline, HCL remains just a slide in a presentation, never appearing on the software screen. 3. Lack of \u201cUser &amp; Scenario\u201d Preset Templates If design tools still only offer generic templates like office \/ factory \/ commercial \/ warehouse and lack HCL-specific scenarios such as children\u2019s learning zones, night-shift nurse stations, elderly bedrooms, or recovery areas, designers are left to figure it out themselves\u2014the tools fail to provide the guidance and educational value they should. 3. In the HCL Era, Five Key Things Lighting Design Tools Can Do As a team with long-term research and field testing experience in HCL \/ light and health, LRS knows that if design tools take just a few steps forward, they can open a whole new door for the industry. Here are five concrete and practical suggestions: 1. Make \u201cVertical Illuminance + Circadian Metrics\u201d a Default Output Once design software visibly displays Ev \/ circadian metrics, designers will start taking them seriously. 2. Introduce \u201cTimeline-Based Scene\u201d Design Thinking This approach helps: 3. Provide \u201cUser \u00d7 Scenario\u201d HCL Templates Each template should include: Designers can adjust these templates rather than starting from scratch. 4. Close the Loop Between Design Tools and Measurement Devices \u2026then the software evolves from being a design-phase tool to a platform spanning design \u2192 commissioning \u2192 verification \u2192 re-measurement. 5. Open APIs for Deep Integration with HCL Models If design software offers: \u2026then: 4. What Can Cohoom, DIALux, and Others Do? Different platforms target different user groups, but the opportunities are clear. For platforms like Cohoom, focused on home design \/ retail \/ visualization: \u2026then you can help thousands of designers and sales staff convince consumers more scientifically: \u201cThis isn\u2019t just a beautiful lighting setup\u2014it\u2019s a light environment that better supports your child\u2019s sleep and vision.\u201d For professional engineering platforms like DIALux, Relux, and AGi32: \u2026then you have the potential to become: \u201cThe default platform for discussions of circadian and healthy lighting in engineering and health-focused building projects over the next decade.\u201d 5. LRS Is Ready to Collaborate to Get This Right Over the years, LRS (Lighting Recipe Studio) has been doing several related things: We understand that integrating HCL capabilities into your products must be scientifically rigorous, yet also user-friendly and cost-effective. If you are a design platform such as Cohoom, DIALux, Relux, AGi32, planning to include HCL \/ WELL \/ healthy lighting modules in your next product version, \u2026bringing HCL from academic papers and classrooms directly into your software interface. 6. Preview of the Next Article: Lighting System Manufacturers Need to Act Today\u2019s article is an invitation to lighting design tool manufacturers: If you don\u2019t embrace HCL, designers will struggle to truly design the light for people\u2019s lives. In the next article, we will turn to another key player: lighting system manufacturers \/ control systems \/ smart lighting platforms. We will discuss: If you are a lighting design tool provider, feel free to share the next article with your partner brands and system manufacturers. The true era of healthy lighting requires tools, products, systems, and designers to upgrade together.","og_url":"https:\/\/lightingrecipe.com\/zh\/a-letter-to-lighting-design-tool-manufacturers-if-you-dont-embrace-human-centric-lighting-hcl-youre-leaving-designers-in-the-past\/","article_published_time":"2025-12-11T03:34:51+00:00","article_modified_time":"2025-12-14T23:35:52+00:00","og_image":[{"width":2528,"height":1696,"url":"https:\/\/lightingrecipe.com\/wp-content\/uploads\/2025\/12\/image_Pippit_202512111100.jpg","type":"image\/jpeg"}],"author":"LRS
