摘要(Abstract):

对于白光LED光源,其亮度和显色指数很难同步提升。本文从LED蓝光激发红色荧光粉和绿色荧光粉混合体的角度进行分析,通过蓝光在LED支架内分别对不同荧光粉进行分离激发,避免了荧光粉之间的相互吸收,从而同步提高白光LED的亮度和显色指数,为LED在未来照明应用市场的升级提供了方案。
For white LED light source, it is difficult to improve its brightness and color rendering index simultaneously. In this paper, we analyze the LED blue light excitation of red phosphor and green phosphor mixture from the perspective of the blue light in the LED holder to separate the excitation of different phosphors, avoiding the mutual absorption between phosphors, so as to improve the brightness and color rendering index of white LED simultaneously, providing a solution for the upgrade of LED in the future lighting application market.
