激光前照灯的道路照明效果研究

Study on Effect of Road Lighting for Laser Headlamp

随着技术的成熟,激光已成为车灯光源的新选择。文章选择2种不同工作原理的白光激光光源,制作符合汽车照明法规要求的远光模组,与传统照明光源进行实验对比。分别设计了3组实验,模拟夜晚的道路照明环境,记录交通标志牌和机动车号牌在不同类型光源的模组照射下反射光的亮度值和色度值,并进行分析。数据显示,激光的亮度特性强于传统光源,但色度表现失真。

With the maturity of technology, laser has become a new choice for the light source of vehicle lamp. We chose two kinds of laser sources with different working principles to design the highbeam modules which meet the requirements of vehicle lighting regulations, and compared with traditional lighting sources. We designed three sets of experiments in night environment, record and analyse the luminance and chromaticity values of the reflected light of the traffic sign and vehicles’ license plates under different types of light sources. The data show that the luminance characteristic of the laser is stronger than the traditional light source, but the chromaticity performance has a certain degree of distortion.
