摘　　要：为解决公路隧道照明高能耗问题,以新型太阳光反射照明技术为依托,开展公路隧道太阳光反射照明技术应用研究。结合太阳光反射照明技术原理和用于隧道入口加强照明的顺光照明实现方式,进行工程应用隧道选址与避免山体遮挡的安装位置分析,由太阳高度角和山体高度及洞门朝向得出符合照明需求的安装区域参数;针对系统安装参数与抛物镜偏转角度对照明区域的影响,建立安装参数与隧道内投射区域之间的关系,并提出避免系统间光线遮挡的安装间距要求。工程测试结果得出:该技术用于隧道入口可提高隧道加强段照明亮度水平达30%以上,具体与所用系统规模有关,并且越往隧道内部照明提升效果越明显,并且亮度变化与隧道行车视觉适应性一致。To reduce the energy consumption of highway tunnel lighting,a novel sunlight reflection lighting technology is applied to highway tunnels.Based on the principle of sunlight reflection lighting technology and the realization of front lighting used to enhance the lighting at tunnel entrance,the site selection of engineering application tunnel and the installation position analysis of avoiding mountain occlusion are conduced.The installation area parameters meeting the lighting requirements are obtained from the sun altitude angle,mountain height,and the orientation of the tunnel entrance.Considering the influence of system installation parameters and the deflection angle of the objective lens on the illumination area,the relationship between installation parameters and the projection area in the tunnel is established,and the requirements of installation spacing between systems to avoid light occlusion are proposed.The engineering test results show that the recommended technology can improve the illumination level of the tunnel intensification section by more than 30%when applied to the tunnel entrance,which is specifically related to the scale of the system used,and the further into the tunnel,the more obvious the lighting enhancement effect is,and the brightness changes are consistent with the tunnel driving visual adaptability.
