摘　　要：针对中短隧道照明设计中缺少供电来源的难题,采用风光互补技术太阳能供电系统,合理利用现有资源,保障隧道机电建设及运营中正常照明。该系统通过结合风光混合发电技术,利用太阳能光伏发电,对隧道内的高亮LED照明系统进行供电。这2套系统相互结合,无需直流向交流转化,从而大大节省了能源损失;并通过合理的改良设计,对蓄电池充放电模块和高亮LED外围电路节能深入研究,改变传统电能转化中的能量损失和照明光转换率。确保蓄电池长时间放电和高亮LED照明系统的低能损耗,即使在恶劣环境下整套系统也能安全稳定运转。系统对现有的太阳能供电关键技术进行改良和工程细节微调,同时对灯具布局进行调整,提高整个照明系统的工作时间,真正达到经济节能的目的。In order to solve the problem of power-source shortage in lighting design for middle and short tunnels, the solar power supply system based on wind-solar hybrid technique was used for tunnel lighting, which could both rely on rational utilization of available resources and ensure the tunnel construction and operation lighting. With the wind-solar hybrid power generation technology, the solar, photovohaic power generation was used for High-Brightness LED lighting in tunnels. This two-system combining sets, in which DC to AC transformation is unnecessary, could greatly avoid energy loss. After researching on the energy saving of storage battery charging and discharging module as well as HB LED peripheral circuit, the energy loss status in traditional energy conversion and lighting conversion rate were improved. The battery＇s long time discharge and low loss of the HB LED system could ensure safety and stability of the tunnel operation even in harsh environments. The system improved the solar-powered key technology and fine-tuned the details of the construction, meanwhile flexibility adjusted the layout of the tunnel lighting to prolong the working hours of the entire lighting system and achieve the goal of economy saving.
