摘　　要：提出一种可用于隧道照明的、基于自旋转原理的太阳光反射照明系统。基于采光系统和出射系统光学中心合一原理分析了系统光学特性,设计出了利于整体封装的高采光量反射照明系统。分析表明,该系统在全方位跟踪太阳光过程中,光学中心始终保持不变,通过设定出射光方向即可实现太阳光定向投射,调节不同安装位置系统的出射角可实现隧道入口太阳光照明的全覆盖,证明了该系统用于隧道入口加强照明的可行性。实验测试表明,由该系统采集投射的太阳光,最高利用率可高达60%,照明距离长达120 m,为目前太阳光直接照明领域相同传输距离下光能利用率最高的技术。该技术的研究和应用对提升高光能需求的公路隧道照明低碳节能环保技术水平,促进公路交通“碳达峰、碳中和”和可持续发展均具有积极的作用。A selfrotating solar reflection lighting system for tunnel lighting is proposed.Based on the principle of integrating the optical center of the lighting system and the outgoing system,the optical characteristics of the system are analyzed and a highlighting reflection lighting system is designed that is conducive to the overall package.The analysis shows that when the system is tracking sunlight in all directions,the optical center remains unchanged.By setting the direction of sunlight projection,the installation positions in the system can be adjusted to realize full coverage of the tunnel entrance for sunlight lighting,which demonstrates the feasibility of the system for strengthening lighting at the tunnel entrance.Experimental tests show that the maximum utilization rate of sunlight by the system is 60%,and the lighting distance is 120 m long,which indicates a technology with the highest light energy utilization at the same transmission distance as that in direct sunlight lighting.The research and application of this technology can promote lowcarbon,energy conservation,and environmental protection technology for highway tunnel lighting that demand high light energy,as well as promote the“carbon peak,carbon neutral”and sustainable development of road traffic.
