摘　　要：针对在G330(洞合线)莲都段平交道口设置太阳能LED路灯以提高夜间道路行车安全的设计安装问题,采用四角布点法对3处具有代表性的路灯进行照明特性的实验研究和模拟验证。结合道路和路灯测试参数,通过DIALux evo软件建立道路和路灯模型,分析模拟结果的可靠性。结果表明:3盏路灯路面平均照度都符合标准要求,其中G330DHX-4路灯的路面照度呈现中间高四周低,中间区域最高照度比另外两盏路灯高出近2倍,易增加行车安全风险,且均匀度低于标准要求;两灯具成180°夹角的路灯放置在斑马线左边或右边对平均照度和照度均匀度均影响不大。文中所建立的模型模拟结果与实验结果吻合较好,误差低于4.99%。Solar LED street lights have been installed at the conflict areas in the Liandu section of G330(Donghe Line) to improve the safety of road traffic at night. In order to understand the lighting conditions of the conflict areas, the four-corner layout method was used to experimental research and simulation verification on the lighting characteristics of three representative street lights. Combined with the road and street light test parameters, the road and street light models were established through the DIALux evo software, and the difference between the simulation results and the measured results is analyzed. The results show that the average road illuminance of the three street lights meets the standard requirements. Among them, the road illuminance of the G330 DHX-4 street light is high in the middle and low in the surrounding areas, and the highest illuminance in the middle area is nearly two times higher than that of the other two street lights, which is easy to increase the risk of driving safety, and the uniformity is lower than the standard requirements. The street lights with two luminaires forming an angle of 180° are placed on the left or right of the zebra crossing, which has little effect on the average illuminance and illuminance uniformity. The simulation results match the experimental results well, the error of which are less than 4.99%.
