摘要

基于半导体激光器激发荧光材料的白光激光照明(wLD)技术在超高亮度照明和显示领域具有重要的应用价值。兼具“高光通量”和“可控发光面积”是wLD实现高亮度的前提条件。因此，荧光材料如何在具备高饱和阈值的前提下，有效地限定发光光斑尺寸，成为该领域的一个热点问题。基于荧光材料微结构设计的散射调控技术为解决该问题提供了可能。本文首先对荧光材料中通过散射设计实现可控发光面积的研究进行了总结；其次探讨了散射系数对材料发光特性的影响；然后介绍了相关研究中的两个关键技术:发光光斑尺寸的测量方法和基于数值模拟的光斑尺寸预测方法；最后展望了相关研究的发展趋势。

Abstract

Novel ultra-high-luminance laser lighting technique based on pumping phosphor by laser diode shows broad application prospect. To achieve high-luminance, a laser lighting luminaire is essential to possess high luminous flux and small light-emitting area. Therefore, it is essential for phosphor to possess both high saturation threshold and strong spot size limitation ability. The microstructure design and scattering control in phosphor materials show potential to solve this problem. In this paper, the studies on spot size of laser lighting were introduced, and the effect of scattering coefficient on the luminescence properties was discussed. After that, some key techniques including measurement and simulation on spot size were presented. Lastly, some future directions were prospected.
