LIGHT-EMITTING ARRANGEMENT

摘要

A light emitting arrangement is provided, comprising: - a light source capable of emitting light of a first wavelength range; - a primary wavelength converting domain arranged to receive light emitted by said light source and capable of converting at least part of the light of said first wavelength range into light of a second wavelength range; - a secondary wavelength converting domain arranged to receive ambient light and capable of converting light into light of a third wavelength range from 470nm to less than 570 nm,wherein said primary wavelength converting domain is arranged between said light source and said secondary wavelength converting domain; and - an optical element arranged in the path of light between said primary and secondary wavelength converting domains. By using the suggested arrangement a desirable off-state green or greenish appearance is obtained, using minor amounts of phosphor and with high light extraction efficiency.
