摘      要：To date,most current reports on the development and optimization of artificial lighting sources have focused on the energy performance levels and limited color qualities of white light-emitting diodes(LEDs).However,these properties are insufficient in terms of representing all performance levels required when adjusting white LEDs for healthy and smart ***,we introduce essential and advanced figures of merit pertaining to circadian performance as well as vision performance and color *** compare all possible properties of commercialized artificial lighting,daylight and four-package white LEDs which consist of long-wavelength pass dichroic filter(LPDF)-capped,phosphor-converted red,amber and green LEDs(pc-LEDs)and a blue *** show that these tunable four-package white LEDs produce a tunable circadian effect for melatonin suppression/secretion,a high color quality for color perception/reproduction,high efficiency for energy savings and tunable figures of merit for the smart LED lighting market.
