照明方式与配光曲线对隧道照明质量的影响分析

为评估不同照明方式与配光曲线对隧道照明质量的影响,文章运用DIALux照明仿真软件建立隧道模型,分析了3种配光类型灯具在不同照明方式下的照明指标。研究结果表明:不同配光曲线照明灯具对路面亮度差异较小,对总体均匀度影响较大。逆光照明会产生严重的眩光,不利于隧道行车安全;顺光照明时亮度最低,有较高均匀度。研究结论可为高速公路隧道照明设计提供理论参考。

Analysis of the influence of lighting method and light distribution curve on tunnel lighting quality

In order to evaluate the influence of different lighting methods and light distribution curves on the quality of tunnel lighting,DIALux lighting simulation software was used to establish a tunnel model,and the lighting indicators of three light distribution types under different lighting methods were analyzed.The results of the study show that the lighting fixtures with different light distribution curves have less difference in road brightness and have a greater impact on the overall uniformity.The reverse beam lighting will produce serious glare,which is not conducive to the safety of tunnel traffic;the front beam lighting has the lowest brightness and high uniformity.The research conclusion can provide theoretical reference for highway tunnel lighting design.
