荧光粉粒子浓度的优化设计是改善白光LED颜色品质和流明效率的重要手段。通过光学仿真方法可以分析荧光粉层不同粒子浓度对LED光强分布和色度均匀性的影响。仿真结果表明
随着荧光粉粒子浓度的增加
荧光粉层对蓝光的散射和吸收增强
LED的流明效率增大
光强分布逐渐变均匀
光斑的色度由蓝光逐渐向白光转变。当荧光粉的粒子浓度为10

The optimal design of the particle number concentration of phosphor is an important way to improve the color quality and lumen efficiency of white LED. Through the method of optical simulation
the optical properties were analyzed under the influence of different particle number concentrations. According to the simulation results
with the increasing of the particle number concentration of phosphor
the absorption and scattering of blue light are strengthened. It is helpful to get the higher luminous efficiency
the better white light spot and uniform chrominance. When the particle number concentration of phosphor is at level of 10
5
/mm
3
the LED light spot has the most uniform light intensity distribution and chrominance
and approximates the standard white light source.
