Title: (EN) Package design for producing white light with short-wavelength leds and down-conversion materials
(ZH) 利用短波长LED和下变频材料产生白光的封装设计
Abstract: front page image
(EN) A broad bandwidth light source including: a solid state light emitting device (102) that generates short wavelength light; and quantum dot material (104) and phosphor material (106) that are each irradiated by some of the short wavelength light. The short wavelength light has a spectrum with a first peak wavelength shorter than about 500nm. The quantum dot material (104) absorbs some of the short wavelength light and reemits it as long wavelength light having a spectrum with a second peak wavelength longer than about 600nm. The phosphor material (106) absorbs some of the short wavelength light and reemits it as mid wavelength light having a spectrum with a peak wavelength between the first and second peak wavelengths. The light source is configured such that some of each light (short, mid, and long wavelength) is emitted coincidently as a light having a chromaticity value near the blackbody locus and a color rendering index greater than 80.
(ZH)

一种宽带宽光源包括:产生短波长光的固态发光装置(102);以及均由一些所述短波长光辐照的量子点材料(104)和荧光粉材料(106)。所述短波长光所具有光谱的第一峰值波长小于约500nm。量子点材料(104)吸收一些短波长光并将其重新发射为长波长光,该长波长光所具有的光谱的第二峰值大于约600nm。荧光粉材料(106)吸收一些短波长光并将其重新发射为具有峰值波长在第一峰值波长和第二峰值波长之间的光谱的中波长光。该光源被配置成使得每种光(短、中、长波长)的一些被同时发射为色度值在黑体轨迹附近并且显色指数大于约80的光。
