公路隧道LED照明的可行性研究

Feasibility study on LED lighting in highway tunnels

针对目前隧道照明主要采用高压钠灯、荧光灯的现状,LED灯的环保、节能等特点决定了它在未来隧道照明领域的地位。通过性能对比与实验研究,LED灯在公路隧道照明中具有很大的优势。不但能解决单一光源给入口段照明带来的问题,同时也体现出了LED灯节能、费用低等优势,从而积极促进了LED灯在公路隧道中的应用。

In view of the status quo that the present tunnel lighting mainly adopts the high pressure sodium lamp and fluo- rescent lamp, the environmental protection and energy saving features of LED lamp have determined its future status in the field of tunnel lighting. The performance comparison and experimental study indicate that LED lights in highway tunnels has a great advantage. LED light resolved the problems caused by single light source in the entrance segment. The advantages of energy-saving and low cost of the LED lamps were reflected in the practical application, thus the application of LED lights in highway tunnels was promoted.
