摘要

研究了不同粒度的YAG : Ce

发光粉对LED亮度的影响

结果显示:粒度越大

封装后LED亮度越高;造成这种结果的主要原因是发光粉颗粒的晶格完整性不同。计算了发光粉在硅胶中的沉降速度

数据说明粒度越大

沉降速度越快

也就越不利于点胶。综合以上两个方面的结果认为发光粉的颗粒不宜太粗或太细

而且分布应该尽可能的窄

10~20 μm是粒径的理想范围。

Abstract

In the article

effect of different particle sizes of YAG : Ce

phosphor on LED brightness and its reasons were studied. The results showed that the larger the particle sizes is

the higher the brightness is

which is attributed to the integrity of crystal lattice of the phosphor particle. The settling rate of YAG : Ce

particles in silica was calculated in detail and analyzed deeply

indicating that the larger particle sizes make the settling velocity to be faster

and also the more difficult dispensing in packaging. Taking into account of the comprehensive consideration of particle size and brightness

we concluded that the particle size should not be too large or too small in order to obtain white LED with more brightness

and the distribution range of the particle size should be narrow as much as possible

10~20 μm distribution may be the best.
