Transforming Artificial Lighting: Enhancing Well-Being through Spectral Engineering of Light Sources

Artificial lighting has undergone significant advancements from historical methods like candlelight to today’s energy-efficient LED technologies, which emphasize both sustainability and the psychological effects of light on human health. While natural daylight is crucial for well-being, many individuals spend over 90% of their lives indoors, leading to a challenge in replicating daylight’s beneficial qualities in artificial lighting, particularly in climates that limit outdoor exposure. Current technologies struggle to mimic daylight’s spectral power distribution and color rendering, affecting mood and health. Researchers are now introducing a new type of light source called TADF-WLED, which combines organic and inorganic elements to create a spectrally tunable system, potentially achieving the light quality necessary for improved circadian health and reduced energy consumption. This innovative approach not only aims to enhance the efficiency and efficacy of artificial lighting but also advances the goal of sustainable and accessible manufacturing through 3D printing, promoting wider application in various settings.
