摘要
本文从路面材质的角度,分析了不同路面反射系数对道路照明中路面亮度的影响.从理论上分析了路面镜面系数的分类及其影响因素,并针对不同镜面系数的路面,分析了蝙蝠型和扇形配光曲线的照明效果.道路模拟结果表明,扇形的偏光型配光曲线比传统的蝙蝠型具有更高的路面亮度均匀性,更能适合不同反射系数的道路.
The impact to the road lighting by the road reflection coefficient is analyzed by the texture of road surface. The classification of road surface coefficient and its influence factor are theoretically analyzed. According to different mirror coefficient of road surface, lighting effects of bat-style and fan-style light distribution curves are analyzed. Simulation results of road lighting show that fan-style light distribution curve has higher brightness uniformity than that the bat-style, and it is more suitable for the roads with different reflection coefficient.
