摘　　要：提出一种针对太阳光反射照明技术的隧道照明设计方法。基于无影照明原理分析了满足隧道照明需求的太阳光反射照明系统安装方式,包括安装位置、相邻设备之间的安装间距和高度差、反光镜的设置角度等,得出可利于工程指导的太阳光反射照明设计方法。结果表明,本技术在隧道洞口两侧采用阵列式安装方式,通过距洞口由近至远安装高度递减或微调反射镜偏转角的方式可将太阳光投射至不同指定区域,可避免前方车辆对光线的全部遮挡实现无影照明效果;在横向方向距洞口由近至远以逐渐接近路沿的方式错位安装,可避免系统间对光线的遮挡实现高效太阳光直接照明效果。该技术的研究对实现高效太阳光直接照明技术在公路隧道应用低碳节能、促进公路交通“碳达峰、碳中和”和可持续发展具有积极的促进作用。A tunnel lighting design method based on sunlight reflection lighting technology is proposed.Based on the principle of shadowless lighting,the installation method of sunlight reflection lighting system to meet the requirements of tunnel lighting is analyzed,including installation position,installation distance and height difference between adjacent devices,setting Angle of reflector,etc,and design method of sunlight reflection lighting which is beneficial to engineering guidance is obtained.The results show that the technology adopts array installation mode on both sides of the tunnel entrance,and the sunlight can be projected to different designated areas by decreasing the height or adjusting the deflection angle of the mirror installed from near to far from the entrance,which can avoid the total occlusion of the light by vehicles in front to achieve shadowless lighting effect.In the transverse direction,it is installed in a staggered manner from near to far away from the entrance and gradually close to the road edge,which can avoid the blocking of light between systems and achieve efficient direct sunlight lighting effect.The engineering application test shows that when the vehicle is blocked in the driving direction,there is still sunlight illumination in front of the vehicle,and the illumination is higher than that without sunlight illumination,indicating that the installation method can achieve the shadowless lighting effect of sunlight illumination in tunnels.The research of this technology will play a positive role in promoting the application of this high-efficiency direct sunlight lighting technology in highway tunnels to achieve low carbon energy saving and promote the“carbon peak,carbon neutrality”and sustainable development of highway transportation.
