自适应远光系统的光学设计与测试

Optical Design and Test of Adaptive Driving Beam

自适应远光系统能够在保证周边照明的情况下,避免对前方车辆造成眩光。目前,对智能前照灯核心光学设计及测试评价方法的研究较少。本文研究了机械式变光和矩阵反射式两种不同原理的远光系统光学设计的方法,并通过配光、响应、变光平顺等测试结果的对比分析,提出了光学设计优化的建议。

The adaptive high beam should avoid glare to the front vehicles, while at the same time ensuring ambient illumination. Although this technology is developing rapidly in Europe, there is still a lack of research on optical design and test methods in China. In this paper, the optical design methods of mechanical dimming and matrix reflection are studied, and the comparison results from light distribution, response time, and smooth dimming are analyzed. Also the suggestion about the objective of optical design optimization is proposed.
