In this work, a phosphor converter with small thickness and low concentration, based on a micro-angle tunable tilted filter (ATFPC), was proposed for hybrid-type laser lighting devices to solve the problem of silicone phosphor converters’ carbonizing under high-energy density. Taking advantage of the filter and the scattering characteristics of microphosphors, two luminous areas are generated on the converter. Compared with conventional phosphor converters (CPCs), the lighting effects of ATFPCs are adjustable using tilt angles. When the tilt angle of the micro filter is 20°, the luminous flux of the ATPFCs is increased by 11.5% at the same concentration; the maximum temperature (MT) of ATFPCs is reduced by 22.8% under the same luminous flux and the same correlated color temperature (CCT) 6500 K. This new type of lighting device provides an alternative way to improve the luminous flux and heat dissipation of laser lighting.

一种具有微角度可调谐滤光片以回收未转换的蓝色激光的光效增强型激光照明装置


本文提出了一种基于微角度可调谐倾斜滤光片（ATFPC）的小厚度、低浓度荧光粉转换器，用于混合型激光照明装置，以解决硅荧光粉转换器在高能下碳化的问题。密度。利用滤光片和微荧光粉的散射特性，在转换器上产生两个发光区域。与传统荧光粉转换器（CPC）相比，ATFPC 的照明效果可通过倾斜角度进行调节。当微过滤器倾斜角度为20°时，相同浓度下ATPFC的光通量增加了11.5%；在相同光通量和相同相关色温（CCT）6500 K下，ATFPC的最高温度（MT）降低了22.8%。这种新型照明装置为提高激光器的光通量和散热提供了替代途径灯光。
