1. First, About ISA: Who is Mapping the Global \u201cLedification\u201d?<\/h4>\n\n\n\n

ISA (International SSL Alliance)<\/strong> is composed of government departments, industry associations, research institutions, and leading companies from multiple countries. It is one of the most important global collaboration platforms in the field of solid-state lighting (SSL). Since its founding, ISA has accomplished three key tasks:<\/p>\n\n\n\n

Bridging: Connecting policy, standards, and industry<\/strong><\/h5>\n\n\n\n
    \n
  • In regions such as China, Europe, and North America, ISA assists governments and standards organizations in aligning SSL technology roadmaps, efficiency targets, and industry realities.<\/li>\n\n\n\n
  • It participates in and promotes the development and revision of energy-efficiency standards, labeling systems, and energy-saving policies across multiple countries.<\/li>\n<\/ul>\n\n\n\n
    Mapping: Providing a \u201cradar and compass\u201d for global SSL development<\/strong><\/h5>\n\n\n\n
      \n
    • Regularly publishes global SSL industry reports and roadmaps.<\/li>\n\n\n\n
    • Systematically analyzes luminous efficacy limits, cost curves, application scenarios, and policy trends.<\/li>\n\n\n\n
    • Serves as an important reference for decision-makers, companies, and investors in forming strategy.<\/li>\n<\/ul>\n\n\n\n
      Accounting: Clarifying the contribution of energy saving and emissions reduction<\/strong><\/h5>\n\n\n\n
        \n
      • Quantifies the impact of improved lighting efficiency on carbon reduction, reduced electricity demand, and infrastructure pressure.<\/li>\n\n\n\n
      • Makes \u201cpromoting LED adoption\u201d not just a technical choice but an inevitable option in energy and climate policy.<\/li>\n<\/ul>\n\n\n\n

        \u7c21\u800c\u8a00\u4e4b\uff1a<\/strong><\/p>\n\n\n\n

        \n

        Without ISA\u2019s decade-plus efforts in bridging, mapping, and accounting, global consensus on replacing traditional light sources with LEDs would not have formed so quickly.<\/em><\/p>\n<\/blockquote>\n\n\n\n

        2. Norman and DOE: Turning Good Technology into Global Policy<\/h4>\n\n\n\n

        One of the lead authors of the SSL Industry Report 2025<\/em> is the well-known Dr. Norman Bardsley<\/strong>. His role bridging ISA and DOE deserves special attention.<\/p>\n\n\n\n

        ISA\u2019s Chief Architect<\/strong><\/h5>\n\n\n\n
          \n
        • Longtime chief analyst\/advisor at ISA.<\/li>\n\n\n\n
        • Integrates policies, technological progress, and industry data into a \u201ccommon language.\u201d<\/li>\n\n\n\n
        • Enables decision-makers from different countries to discuss the future on the same map.<\/li>\n<\/ul>\n\n\n\n
          Key Strategist for DOE SSL Program<\/strong><\/h5>\n\n\n\n
            \n
          • Has participated for many years in the U.S. Department of Energy (DOE) Solid-State Lighting (SSL) Program.<\/li>\n\n\n\n
          • Helps set target efficacies, cost pathways, technical milestones, and demonstration projects.<\/li>\n\n\n\n
          • Turns \u201creplacing traditional light sources with LEDs\u201d into a national-level project with a roadmap and timeline.<\/li>\n<\/ul>\n\n\n\n
            Translating Technological Evolution into Industry Decisions<\/strong><\/h5>\n\n\n\n
              \n
            • He focuses not only on laboratory limits but also on commercial viability: when can it reach the market? When will costs be acceptable? Which applications benefit first?<\/li>\n\n\n\n
            • This is why his reports can persuade both the technical community and policy-makers, as well as investors.<\/li>\n<\/ul>\n\n\n\n
              \n\n\n\n

              3. Our Personal Experience: From \u201cFull Spectrum\u201d Skepticism at DOE to Today\u2019s HCL Consensus<\/h4>\n\n\n\n

              Lawrence Lin also has a personal connection with Norman.<\/p>\n\n\n\n

              In early 2019, at Norman\u2019s invitation, Lawrence Lin attended the DOE SSL R&D Workshop representing LEDVANCE and delivered a keynote titled:<\/p>\n\n\n\n

              \u201cTowards the Era of Full Spectrum LED Lighting.\u201d<\/em><\/p>\n\n\n\n

              At that time, many were skeptical about \u201cFull Spectrum\u201d:<\/p>\n\n\n\n

                \n
              • Some thought it was merely a marketing term.<\/li>\n\n\n\n
              • Others questioned why so much effort should be spent on spectral quality under tight efficiency and cost pressures.<\/li>\n<\/ul>\n\n\n\n

                Looking back today, Full Spectrum LEDs became one of the key physical enablers for Human-Centric Lighting (HCL):<\/p>\n\n\n\n

                  \n
                • Without LEDs closer to the natural spectrum, tunable, and easily measurable and controllable, discussions about circadian rhythm, mood, and visual comfort would have remained confined to labs and PowerPoints.<\/li>\n\n\n\n
                • For HCL to truly reach schools, hospitals, offices, and urban spaces, there first had to be a \u201cgood, well-behaved\u201d light source.<\/li>\n<\/ul>\n\n\n\n

                  Lawrence Lin has always valued the intense discussions with Norman and DOE colleagues at that meeting. Many of the points that were questioned at the time have since become industry consensus.<\/p>\n\n\n\n

                  \n

                  From \u201cmaking LEDs more energy-efficient\u201d to \u201cmaking light more human-centric,\u201d the bridge between these two was precisely \u201cFull Spectrum + measurable human-factor metrics.\u201d<\/strong><\/em><\/p>\n<\/blockquote>\n\n\n\n

                  \"\"<\/figure>\n\n\n\n

                  4. After the \u201cEnergy-Saving Campaign\u201d Was Declared Victorious<\/h4>\n\n\n\n

                  Over the past twenty years, driven by institutions such as ISA and DOE, global policies, subsidies, and research funding have elevated LEDs to a central position:<\/p>\n\n\n\n

                    \n
                  • The average efficacy of artificial lighting worldwide increased from about 50 lm\/W in 2005 to nearly or over 100 lm\/W by 2025.<\/li>\n\n\n\n
                  • Humanity\u2019s \u201cuse of light\u201d has almost doubled \u2014 longer lighting hours, higher brightness, and more complex scenarios. We have never been more adept at using light than we are today.<\/li>\n<\/ul>\n\n\n\n

                    However, in 2024\u20132025, several key signals emerged:<\/p>\n\n\n\n

                    Governments say, \u201cIt\u2019s time to step back.\u201d<\/strong><\/h5>\n\n\n\n
                      \n
                    • Many countries are gradually reducing dedicated SSL funding.<\/li>\n\n\n\n
                    • Relevant international projects are completing their phases \u2014 the energy-saving light bulb battle is largely over.<\/li>\n<\/ul>\n\n\n\n
                      Industry media bows out<\/strong><\/h5>\n\n\n\n
                        \n
                      • Long-established professional media are either closing or transforming, and the industry focus is quietly shifting from \u201cluminous efficacy and devices\u201d to \u201capplications and scenarios.\u201d<\/li>\n<\/ul>\n\n\n\n
                        Efficiency rises, electricity use doesn\u2019t drop significantly<\/strong><\/h5>\n\n\n\n
                          \n
                        • Lighting electricity consumption has not halved despite doubled efficacy; in some years, it even slightly increased. Efficiency gains are outweighed by \u201cmore light, larger areas, longer hours.\u201d<\/li>\n<\/ul>\n\n\n\n
                          \n

                          Our view:<\/strong>
                          The \u201cenergy-saving light bulb battle\u201d is over. In the next decade, companies focused solely on lm\/W will gradually lose influence. The new battleground is: light and humans, light and health, light and spatial value.<\/em><\/p>\n<\/blockquote>\n\n\n\n

                          5. China\u2019s LED Industry: Revenue Up, Profits Hollowed Out<\/h4>\n\n\n\n

                          The report\u2019s analysis of China\u2019s LED industry is particularly eye-opening:<\/p>\n\n\n\n

                            \n
                          • Listed companies focusing on LEDs still see overall revenue growth, but net margins continue to decline, with industry-wide profitability negative.<\/li>\n\n\n\n
                          • Gross margins for packaging and general lighting businesses are low, and capacity utilization has fallen below warning levels.<\/li>\n\n\n\n
                          • Export volumes remain substantial, but unit prices have dropped significantly, with many categories experiencing double-digit declines within a year.<\/li>\n<\/ul>\n\n\n\n
                            This means:<\/strong><\/h5>\n\n\n\n
                            Volume rises, \u201cvalue\u201d collapses<\/strong><\/h5>\n\n\n\n
                              \n
                            • Production lines are running, orders are not few, but net profits are thinning or even turning into losses.<\/li>\n<\/ul>\n\n\n\n
                              China is the global \u201cLED granary,\u201d not the price setter<\/strong><\/h5>\n\n\n\n
                                \n
                              • Upstream in modules, light sources, and fixtures, the true leverage for project influence and brand premium lies in systems and solutions.<\/li>\n<\/ul>\n\n\n\n
                                Price wars have exhausted traditional profit models<\/strong><\/h5>\n\n\n\n
                                  \n
                                • Competing only on wattage, materials, and cost, without shifting to \u201cgood light + good space + good systems,\u201d leads only to exhaustion.<\/li>\n<\/ul>\n\n\n\n
                                  \n

                                  Our judgment:<\/strong>
                                  If Chinese lighting companies continue to view the world through \u201cadd more lines, make more molds\u201d in the next five years, today\u2019s financial reports may already be the most \u201cpresentable\u201d pages.<\/em><\/p>\n<\/blockquote>\n\n\n\n

                                  6. Application Scenarios: Where Is the Real \u201cSecond Growth Curve\u201d?<\/h4>\n\n\n\n

                                  The ISA report analyzes mainstream applications separately: automotive, horticultural, roadway, displays, UV, NIR, and smart lighting. Here are a few critical for Chinese companies:<\/p>\n\n\n\n

                                  1. Horticultural Lighting: From Hype to Financial Reality<\/strong><\/h5>\n\n\n\n
                                    \n
                                  • The global LED horticultural lighting market is still growing, but growth is becoming rational.<\/li>\n\n\n\n
                                  • Several vertical farm projects in Europe and the U.S. suffered losses or bankruptcy \u2014 the accounting isn\u2019t about fixtures, but the entire business model.<\/li>\n<\/ul>\n\n\n\n

                                    Summary:<\/strong><\/p>\n\n\n\n

                                      \n
                                    • Fully artificial-light vertical farms have extremely high building, energy, and equipment costs. Without clear crop positioning and supply chain design, profitability is difficult.<\/li>\n\n\n\n
                                    • More promising are high-value crops like leafy greens, herbs, microgreens combined with renewable energy and precise control.<\/li>\n<\/ul>\n\n\n\n
                                      \n

                                      Conclusion:<\/strong>
                                      Chinese companies in horticultural lighting should not just sell \u201clights,\u201d but provide an integrated solution of crops + algorithms + energy + business model.<\/strong><\/em><\/p>\n<\/blockquote>\n\n\n\n

                                      2. Automotive Lighting: Technical High Ground, Not a \u201cLifesaver\u201d<\/strong><\/h5>\n\n\n\n
                                        \n
                                      • The automotive LED device market continues to grow, led by a few international brands.<\/li>\n\n\n\n
                                      • Technologies such as ADB adaptive high\/low beams and dynamic taillights continue to evolve, but regulations, OEM platforms, and reliability requirements make this a slow-paced, high-entry-barrier field.<\/li>\n<\/ul>\n\n\n\n
                                        \n

                                        My view:<\/strong>
                                        Automotive lighting is suitable for building technical and brand prestige but is unlikely to solve large-scale overcapacity in the short term. A more pragmatic approach is to reverse-apply automotive-grade optics and reliability thinking to human-centric lighting in buildings and cities.<\/em><\/p>\n<\/blockquote>\n\n\n\n

                                        3. Micro-LED and Displays: A Marathon of Capital and Time<\/strong><\/h5>\n\n\n\n
                                          \n
                                        • Some leading micro-LED companies saw revenue growth and narrowed losses from 2022\u20132024, but in 2025, inventory, exchange rates, and demand fluctuations caused sharp revenue drops and widening losses.<\/li>\n<\/ul>\n\n\n\n
                                          \n

                                          For most lighting companies:<\/strong>
                                          Micro-LED is more like a \u201cticket to technical influence\u201d rather than a \u201cmain business savior\u201d in the next 3\u20135 years.<\/em><\/p>\n<\/blockquote>\n\n\n\n

                                          7. Human Factors and Health: HCL Becomes a Hard Metric<\/h4>\n\n\n\n

                                          In recent years, from DOE to IES, CIE, and then WELL and LEED, everyone has been pursuing the same goal:<\/p>\n\n\n\n

                                            \n
                                          • Transform \u201cgood light\u201d from an adjective into measurable, deliverable engineering language.<\/li>\n<\/ul>\n\n\n\n

                                            The report highlights three aspects in the \u201cLight and Health\u201d section:<\/p>\n\n\n\n

                                            Circadian Impact<\/strong><\/h5>\n\n\n\n
                                              \n
                                            • Expert consensus recommends daytime melanopic EDI at the eye level to support stable circadian rhythm and nighttime sleep.<\/li>\n\n\n\n
                                            • Under constraints of efficiency and glare, achieving full compliance using only electric light sources is not easy.<\/li>\n<\/ul>\n\n\n\n
                                              Blue Light and Photobiological Safety<\/strong><\/h5>\n\n\n\n
                                                \n
                                              • Typical residential lighting poses minimal skin risk; the main concern is high blue light output and retinal risk for specific sensitive populations.<\/li>\n\n\n\n
                                              • This requires finer classification and more empirical research.<\/li>\n<\/ul>\n\n\n\n
                                                Glare and Temporal Light Modulation (TLM)<\/strong><\/h5>\n\n\n\n
                                                  \n
                                                • The point-source nature of LEDs and certain dimming methods complicates glare and flicker issues. Headaches, fatigue, migraines, and photosensitive epilepsy can be associated with improper TLM characteristics.<\/li>\n<\/ul>\n\n\n\n
                                                  This echoes Full Spectrum LED:<\/strong><\/h5>\n\n\n\n
                                                    \n
                                                  • Without better spectral carriers, HCL cannot be truly implemented.<\/li>\n\n\n\n
                                                  • Full Spectrum + measurable human-factor metrics is the essential bridge from concept to engineering practice.<\/li>\n<\/ul>\n\n\n\n

We want to discuss: as the energy-saving dividend reaches its peak, what will the lighting industry rely on to survive next? (Photo of Lawrence Lin delivering a presentation on stage at the 2019 DOE SSL R&D Workshop) 1. First, About ISA: Who is Mapping the Global \u201cLedification\u201d? ISA (International SSL Alliance) is composed of government departments, industry associations, research institutions, and leading companies from multiple countries. It is one of the most important global collaboration platforms in the field of solid-state lighting (SSL). Since its founding, ISA has accomplished three key tasks: Bridging: Connecting policy, standards, and industry Mapping: Providing a \u201cradar and compass\u201d for global SSL development Accounting: Clarifying the contribution of energy saving and emissions reduction In short: Without ISA\u2019s decade-plus efforts in bridging, mapping, and accounting, global consensus on replacing traditional light sources with LEDs would not have formed so quickly. 2. Norman and DOE: Turning Good Technology into Global Policy One of the lead authors of the SSL Industry Report 2025 is the well-known Dr. Norman Bardsley. His role bridging ISA and DOE deserves special attention. ISA\u2019s Chief Architect Key Strategist for DOE SSL Program Translating Technological Evolution into Industry Decisions 3. Our Personal Experience: From \u201cFull Spectrum\u201d Skepticism at DOE to Today\u2019s HCL Consensus Lawrence Lin also has a personal connection with Norman. In early 2019, at Norman\u2019s invitation, Lawrence Lin attended the DOE SSL R&D Workshop representing LEDVANCE and delivered a keynote titled: \u201cTowards the Era of Full Spectrum LED Lighting.\u201d At that time, many were skeptical about \u201cFull Spectrum\u201d: Looking back today, Full Spectrum LEDs became one of the key physical enablers for Human-Centric Lighting (HCL): Lawrence Lin has always valued the intense discussions with Norman and DOE colleagues at that meeting. Many of the points that were questioned at the time have since become industry consensus. From \u201cmaking LEDs more energy-efficient\u201d to \u201cmaking light more human-centric,\u201d the bridge between these two was precisely \u201cFull Spectrum + measurable human-factor metrics.\u201d 4.
