随着近年来激光在汽车领域的兴起, 使用激光车灯代替普通LED车灯已成为不可阻挡的趋势, 但目前国内对激光车灯照明研究相对较少。本文首先依据450 nm蓝光激光器对不同厚度的荧光陶瓷片所产生光亮度进行研究、其次使用450 nm对不同材料的荧光陶瓷片所产生的亮度进行了对比分析, 并简述了其变化规律和物理机制, 实验结果表明控制荧光陶瓷片的厚度和材料可以有效地改变激光照射在荧光陶瓷片上所产生的光亮度, 从而为激光照明在荧光陶瓷片的选择提供一种新的思路。

With the rise of laser in the automotive field in recent years, it has become an irresistible trend to use laser car lights to replace ordinary LED car lights. However, there are relatively few studies on laser car lights in China. This paper based on the 450 nm blue laser fluorescence of different thickness of ceramic chip produced by brightness is studied, secondly, using the 450 nm fluorescent ceramic pieces of different materials produced by the brightness contrast analyses, and the change rule and the physical mechanism is introduced, the experimental results show that controlling fluorescent ceramic chip thickness and the material can effectively change the brightness on the fluorescent ceramic chip. Laser illumination on the choice of fluorescent ceramic chip provides a new idea and thought.
