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。
In the tunnel lighting, natural light is a double-edged sword, on the one hand can improve the brightness of the tunnel, on the other hand can also cause “white hole ” effect, threatening the vehicle driving safety. Making full use of the synergistic effect of natural light on tunnel lighting and reducing the energy consumption of artificial lighting are one of the effective ways to realize the energy saving of tunnel entrance lighting. Combined with the natural light in Lushan tunnel of Yunnan Bund Expressway and the measured data of the illumination in different depths of the tunnel under natural light and LED lamp illumination, the natural light, LED light composite Lighting under the tunnel illumination distribution law, and evaluated the energy-saving effect. In the future, it will provide references for further researching the energy-saving of tunnel compound lighting using natural light and artificial light source.
