城市道路车辆行驶照明范围需求研究

Research on Requirements of Lighting Area on China City Roads

根据CIE 188技术报告提出的评估维度,结合中国城市道路的设计参数,对车辆前照灯夜间照明范围进行了系统分析和研究,为同行业后续关于前照灯光学设计和整车前照灯性能评估提供了设计思路和参考。

In this paper, according to the evaluation dimensionality referred in CIE 188 technical report, and combined with China city road design parameters, this article analyzes the lighting area of vehicle headlight by night;Provides design ideas and reference for headlight optics design and vehicle headlight performance evaluation which can be used for the follow-up design.
