为研究隧道内布灯方式对隧道照明的影响,利用Ecotect照明仿真软件建立隧道模型。在隧道模型中,对对称布灯、交错布灯和中央布灯3种布灯方式进行仿真模拟。在相同的隧道条件下,采用相同的隧道照明灯具,模拟了路面照度、路面平均亮度和照度均匀度等参数,得到了仿真结果。仿真结果表明,在3种布灯方式中中央布灯方式的照明效果最好,交错布灯方式照明效果次之,对称布灯方式照明效果最差。通过模拟仿真,可选取最优的布灯方式,从而提高照明设计效率。
In order to study the influence of the cloth lamp in the tunnel on the lighting of the tunnel, a tunnel model was established by using Ecotect lighting simulation software. In the tunnel model, we simulated the three kinds of cloth lamps with symmetrical cloth lamp, staggered cloth lamp and central cloth lamp. Under the same tunnel conditions, the same tunnel lighting fixture was used to simulate the parameters of pavement illumination, average brightness and uniformity of illumination, and the simulation results were obtained. The simulation results show that the lighting effect of the central lighting system is the best among the three kinds of lighting methods, the lighting effect of the staggered lighting method is the second, and the lighting effect of the symmetrical lighting system is the worst. Through simulation, we can choose the best way of cloth lamp, so as to improve the efficiency of lighting design.
