为了满足近几年来隧道建设的迅速发展, LED灯具逐步突显其在隧道照明中的应用优势. 设计隧道为分段长隧道, 结合其洞口形式、 行车速度、 洞口方向、 连续隧道亮度折减等特点, 确定隧道照明亮度设计标准后, 应用LED灯对隧道进行照明设计, 计算并图示分析了采用LED光源的灯具选择及布置方式. 同时利用LED光源的特点, 采用无级控制系统对隧道照明进行调光控制. 在对LED灯与高压钠灯进行比较分析后可以看出, LED光源用于隧道照明虽然初始投资比较高, 但是在运营维护频次及用电费用方面都低于传统高压钠灯. 从长远角度来看, LED照明是一种非常节能的绿色照明, 且在照明控制方式上能够实现无级控制, 充分体现了LED照明的优点和应用于公路隧道的优势, 为解决隧道照明提供了一种全新的思路.%In order to meet the rapid development of tunnel construction in recent years , LED light gradually highlights its application advantages in the tunnel lighting .The design tunnel is a segmented long tunnel.After considering the characteristics of its entrance form , driving speed, the hole direction, continuous tunnel brightness reduction , etc., and determining the tunnel illumination design standard , LED lamps are chosen for tunnel lighting .The selection and arrangement of LED lamps are calculated and analyzed in graphics .While taking advantage of the characteristics of LED light , non-polar control system is used to conduct the tunnel lighting dimming control .After the comparative analysis of LED and HPS ( High Pressure Sodium ) we can see that , although the initial investment of LED light is relatively high , the frequency of operation and maintenance and electricity costs are lower than that of traditional HPS .In the long run, LED lighting is a very energy-efficient green lighting , and the lighting control enables non-polar control , which fully embodies the advantages and benefits of LED lighting ' s usage in highway tunnel .It provides a new way of thinking to solve tunnel lighting .
