隧道入口段复合照明节能试验研究

在隧道照明领域,自然光是一把双刃剑,一方面可以提高隧道内亮度,另一方面也可引起“白洞”效应,威胁车辆行驶安全。充分利用自然光对隧道照明的增效作用,降低人工照明的能耗,是实现隧道入口段照明节能的有效途径之一。结合云南保腾高速公路鹿山隧道内自然光、以及自然光与LED灯复合照明下隧道不同纵深路面照度的实测数据,通过与规范规定值的对比分析研究,得到了隧道入口段各区段自然光、LED灯复合照明下隧道照度分布规律,并对节能效果进行了评价。为今后进一步合理利用自然光、人工光源进行隧道复合照明节能研究提供参考。

Experimental Study on Energy Saving of Composite Lighting in Tunnel Entrance Section

In the tunnel lighting field,natural light is a double-edged sword,on one hand,it can improve the luminance in tunnel,on the other hand,it will cause "white hole" effect,which threaten vehicle safety.Making full use of the synergism of natural light effect on tunnel lighting to reduce energy consumption of artificial lighting is one of the most effective ways to realize tunnel lighting energy saving in entrance section.Based on different depths road illumination measured in Lushan tunnel under the condition of natural light and LED lamps composite lighting,measured data were contrasted with the standard values,the distribution law of tunnel illumination of composite lighting was got to evaluate its energy saving effect.The paper can provide the reference for tunnel lighting energysaving in reasonable use natural light and artificial light composite lighting.
