文章阐述了蓄反光材料的发展,针对公路隧道中的能耗与安全问题,开展了两类蓄反光材料反光的性能试验及光谱实验,基于中间视觉理念引入了光谱S/P值的计算方法,系统地分析了隧道蓄反光侧壁材料在隧道内辅助节能照明方面的应用效果,研究表明:(1)蓄反光侧壁材料的实测漫反射率为80%左右,初步估算蓄反光侧壁材料在隧道内可节约15%左右的电能;(2)由于蓄反光侧壁材料独特的材料组成,其反光作用对隧道LED灯与汽车大灯的光谱分布均有显著的改善作用,能够提高原光源的光谱S/P值;(3)S/P值的大小规律符合人眼在中间视觉亮度条件下对光色敏感程度的理论认知,是一种较为有效、合理的隧道反光光谱的评价方法。
In this paper, the development of light-reflecting material is described. According to the energy consumption and safety issues in highway tunnels, the performance tests and spectral experiments of two types of light-reflecting materials are carried out. Based on the concept of intermediate vision, the calculation method of spectral S / P value is introduced. The results show that: (1) The measured diffuse reflectance of the retroreflective side wall material is about 80%. The preliminary evaluation of the retroreflective side wall material in the tunnel The tunnel can save about 15% of the electrical energy; (2) due to the unique reflective material of the reflective wall material, the reflective effect of the tunnel LED lamps and car headlights spectral distribution have a significant role in improving the original light source Spectral S / P value; (3) S / P value of the size of law in line with the human eye under the conditions of intermediate visual light sensitivity to the light perception of the degree of theory is a more effective and reasonable evaluation of the tunnel reflection spectroscopy.
