三车道公路隧道照明灯具布置参数研究

随着公路隧道数量和里程的增加,隧道运营过程中的照明将会消耗更巨大的电能,这是运营单位所承担的主要负担,如何有效的降低该能耗已经成为重要的问题。国内外专家学者对此作了大量研究,通常使照明灯具达到最好的照明效果是降低电能消耗的有效途径之一。采用DIALux照明仿真软件,分别建立隧道照明灯具两侧对称布置和交错布置模型,以洞内路面亮度、照度和均匀度满足交通安全要求为约束条件,分析了不同布灯形式和灯具不同照射角度情况对隧道内照明环境的影响,通过综合分析比较,得出当灯具交错布置、发光轴线与竖直面夹角为15°时的照明环境最好。

Study on Parameters Optimization of Luminaire Distribution of Three-Lane Highway Tunnel

In the process of tunnel operation,lighting consumes huge energy with the increases of the number of highway tunnel and mileage.This is the main burden of operating units.So it is important to effectively reduce the energy consumption of tunnel lighting.Domestic and foreign experts have made a lot of research.It is one of the ways for reducing the power consumption to make the lighting lamps reach the best lighting effects.This article sets up tunnel lighting models of symmetrical and staggered lamps by using the DIALux lighting calculation software.The influence of the tunnel lighting environment was analyzed under the different luminaire-distribution-styles and angles with luminance and illuminance of road surface meeting the traffic safety requirement as constraint condition.The results show that lighting effects of staggered luminaire distribution is the best,meanwhile,the angle of light axis and the vertical is 15 degree.
