What is Human Centric Lighting? - An illuminating talk by Professor Warren Julian Human Centric Lighting Design is an old Concept, given that our circadian clock runs on a 24-hour cycle. But It was difficult to maintain the circadian entrainment effectively with traditional lights. With the advent of LED, having expanded color capabilities, and seamless control on color changes and dimming, a lot of research is underway to make our visual system respond more effectively to the light stimulus. Dynamic Tunable LED, varying lighting   has always been human-centric  Spectrum from 6500K to 2700K has increased the circadian effectiveness of the human system. Increasing daytime alertness and nighttime sleep can be addressed in the near future by acutely synchronizing the circadian system of human beings with proper doses of red and blue light. A brilliant presentation on Human Centric Lighting was made at the Hong Kong International Lighting Fair 2017 by Professor Warre...
