White light LED module with green and red phosphors and illumination device having the same

机译:具有绿色和红色荧光粉的白光LED模块和具有该模块的照明装置

摘要

Provided is an LED module and an illumination device having high color saturation, which improve vividness of color of an illuminated object even if color temperature of ambient light is high, and consequently are able to reproduce colors of the object as desired. Blue LEDs have peak wavelength of 420 nm to 470 nm and FWHM of greater than 0 nm and no greater than 50 nm. A green phosphor has peak wavelength of 500 nm to 535 nm and FWHM of 100 nm to 110 nm. A red phosphor has peak wavelength of 610 nm to 670 nm and FWHM of 85 nm to 95 nm. Mixed-color light of the blue, green and red light has correlated color temperature of 4600 K to 7200 K and Duv of −12 to −6.
