| 摘 要： | 根据坡路照明的视觉特点,从行车视距出发,对坡路照明的照明特点和照明需求进行研究。分析计算了不同坡度下相同布灯参数下的路面亮度照明效果,并与平直路作比较,得到道路坡度对照明效果的影响关系;并在某一坡度下,以最小能耗为目标,以某款灯具为具体对象,依据道路照明的亮度标准,对其最佳布灯间距进行了优化计算,在上、下坡路段不同布灯间距的条件下,获得了良好的照明效果。

| Abstract: | Based on visual characteristic of slope lighting,the feature and demand of slope lighting is researched,which is proceeded from sight distance. In the condition of the same lamp setting parameters,the luminance distribution of slope with different gradient is analyzed. By comparing that of level straight road,the relation between gradient of slope and lighting effect is deduced. Then,with the goal of energy saving,the optimum luminance spacing is optimized,which is based on the luminance standards of road lighting. And the better lighting effect is gotten with the different lamp spacing of the slope with different gradient. |
