针对荧光粉层厚度对激光照明的影响展开研究, 采用自行设计的反射式照明模块进行测试, 利用独创的荧光粉层厚度确定方案精确地确定厚度。通过实验分析得出: 随着荧光粉层厚度的增加, 光通量逐渐增大, 在荧光粉层厚度达到600 μm之后呈现下降趋势; 在荧光粉层厚度达到600 μm之前, 蓝光含量呈下降趋势, 600 μm后略有上升, 但整体趋于稳定; 色温与蓝光含量变化趋势相同, 存在正比关系。同时, 本文还验证了光分布密度对激光照明有很大影响。

This paper launched research on the influence of the phosphor layer thickness of laser lighting, and adopted the self-designed reflex lighting module to test. The original scheme of making fixed thickness phosphor layer was used to determine the thickness accurately. With the increasing of the phosphor layer thickness, the flux increases gradually, and presents downtrend after the phosphor layer thickness is over 600 μm. The blue light content shows downtrend before the phosphor layer thickness is 600 μm, and rises slightly after 600 μm, but the overall is stability. The color temperature and blue light content have the same change trend with a proportional relationship. At the same time, this article also verifies the light distribution density has a great influence on the laser illumination.
