为了检验软件模拟道路照明特性的可行性, 从几种不同配光曲线的LED路灯的仿真结果出发, 按照规范的方法实测了它们的路面照度。比较发现, 同一路面上各点的照度与仿真值之间有着相同的比值。进一步计算发现, 两者的照度均匀度相等。这表明仿真软件能比较准确地反映路灯的路面照明效果。另外, 还研究了路灯的光衰性能, 发现散热性能好的灯具光衰更慢, 寿命更长。

In order to verify the feasibility of the software simulation on road lighting characteristics, the road illuminations of several kinds of LED street lamps with different light distribution curve were measured, according to their simulation results and standard methods. By comparison, it is found that the ratios of actual illumination to simulation value are equal for different test points on the same road. Further calculations indicate that the both illuminance uniformity are the same. These results show that simulation software can accurately reflect the road lighting conditions. Besides, the luminous decay performance of the road lamps was also studied. The results show that the lamps with better heat dissipation performance decay more slowly and work longer.
