摘要
为研究高速公路隧道照明最佳环境,采取三维软件结合实际工程情况开展仿真模拟,分析不同LED灯安装角度、发光材料涂装高度与反射率对隧道照明的影响。研究结果表明:(1)随灯具安装角度扩大,路面照度值不断变化,50°时最高,90°时最低,对路面照度均匀值影响呈倒“U”形。照度均匀值是60°以下无影响,60°及以上照度均匀度迅速降低。(2)发光材料反射率与涂装角度提升,路面照度、照度均匀值均随之提升。(3)隧道眩光受发光材料反射率、灯具安装高度影响,反射率与灯具高度增加,眩光值也随之增加,材料反射率> 70%,灯具角度> 40°,易生成有害眩光。工程结合实际情况,确定最佳涂装高度4.0 m、反射率60%、灯具角度20°,采取软件仿真模拟,有助于提高隧道照明设计质量。
In order to study the optimal lighting environment of highway tunnel,3D software was used to simulate the actual engineering situation,and the influence of different LED lighting installation angles,luminous material coating height and reflectivity on tunnel lighting was analyzed.The results show that:(1)With the expansion of the lamp installation angle,the road surface illuminance value changes constantly,the highest at 50°,the lowest at 90°,the influence on the road surface illuminance uniformity value is inverted“U”shape.The uniformity value of illumination is no effect below 60°,and the uniformity of illumination decreases rapidly after 60°and above.(2)The reflectance of the luminous material and the coating angle are increased,and the illumination of the road surface and the uniform value of illumination are increased accordingly.(3)The tunnel glare is affected by the reflectivity of the luminous material and the installation height of the lamp,the reflectivity and the height of the lamp increase,the glare value also increases,the material reflectivity>70%,the lamp angle>40°,and it is easy to produce harmful glare.according to the actual situation,the best painting height of 4.0m,reflectivity of 60%and lamp angle of 20°are determined,and software simulation is adopted to improve the quality of tunnel lighting design.
