Healthy, natural, efficient and tunable lighting: four-package white LEDs for optimizing the circadian effect, color quality and vision performance

摘要: Researchers in Korea have discovered that carefully designed white LEDs can help optimize an individual's circadian rhythm. Ji Hye Oh and co-workers from Kookmin University studied four-package LEDs, which consist of phosphor-converted red, amber green a blue LED long-wavelength dichroic filter. They compared these devices with variety traditional forms lighting, found such designs yield high luminous efficacy, excellent color rendering tunable effect for regulating the secretion melatonin. The figures merit suggest could play important role creating smart lighting systems maintain good health, bring energy savings provide optimal visualization colors.
