摘　　要：为解决隧道入口段加强照明的高能耗问题,提出一种集采光系统、传输系统和出射系统于一体,光利用率可达60%以上的新型高效隧道入口段太阳光直接照明系统。其中,采光系统采用自主研发的新型自由曲面透镜,并使用四象限光电检测法作为光跟踪算法;传输系统的传输光纤采用通光量大、传输损耗低且抗弯性强的石英光纤,并基于理论推导和现场试验得到系统光利用率最大时的光纤耦合头高度;出射尾灯具有对传输光线进行二次配光的优点,配光后的光强分布接近隧道常用LED灯。基于太阳光直接照明系统工程应用后的试验测试结果,得到以下结论:1)系统应用后不同季节和时刻下的路面亮度大于细则规定的亮度,满足行车安全性要求;2)新型太阳光直接照明方案较传统电光照明方案实现节能65%以上,在10年使用寿命内可节约24.4%的成本,兼具节能性和经济性。To minimize the energy consumption in tunnel entrance lighting,a novel efficient solar direct lighting system is proposed.The system integrates lighting system,transmission system,and exit system,with a light utilization rate reaching over 60%.The lighting system uses a novel self-developed free-form surface lens,and employs the four-quadrant photoelectric detection method as the light tracking algorithm.The transmission fiber of the transmission system adopts the quartz fiber with large optical capacity,low transmission loss,and strong bending resistance.Based on theoretical deduction and field test,the coupling head height of the fiber is obtained when the system light utilization rate reaches the maximum.The exit taillights can secondarily distribute the transmitted light,and the distribution of light intensity after distribution is close to that of the commonly used LED lights in tunnels.Based on the test results of this system,the following conclusions are obtained:(1)The brightness of the road surface in different seasons and times is greater than the brightness specified in the standards,meeting the requirements of driving safety.(2)An energy conservation of more than 65%is achieved compared to traditional electro-optical lighting scheme,and a 24.4%cost within 10 years of service life can be saved,showing energy and economic benefits.
