城市隧道照明灯具优化布置研究

Study on Optimization of Luminaries Distribution in Urban Tunnel

以某城市隧道照明设计为例,采用DIALux软件建立了隧道中间段照明模型,分析比较了LED陶瓷隧道照明灯具和LED反射式隧道照明灯具在不同安装角度时城市隧道路面平均亮度、路面亮度总均匀度和路面中线亮度纵向均匀度。研究结果表明:在总功率和安装高度相同的条件下,LED陶瓷隧道照明灯具的路面平均亮度高于LED反射式隧道照明灯具;LED陶瓷隧道照明灯具的路面亮度总均匀度在安装角度5~60°范围内低于LED反射式隧道照明灯具;LED陶瓷隧道照明灯具的路面中线亮度纵向均匀度在安装角度大于5°时高于LED反射式隧道照明灯具;LED陶瓷隧道照明灯具最佳安装角度为20°,LED反射式隧道照明灯具最佳安装角度为0°。相关结论可为类似城市隧道照明设计提供参考。

Based on lighting design for an urban tunnel,DIALux was used to construct the lighting model at the intermediate section.The average road surface luminance,overall uniformity of road surface luminance,and longitudinal uniformity of road surface luminance were analyzed and compared under different installation angles of LED ceramic tunnel lamp and LED reflective tunnel lamps.The results show that the average road surface luminance of LED ceramic tunnel lamp is higher than that of LED reflective tunnel lamp under the same conditions of total power and installation height;The overall uniformity of road surface luminance of LED ceramic tunnel lamp is lower than that of LED reflective tunnel lamp when the installation angels is 5~60°;The longitudinal uniformity of road surface luminance of LED ceramic tunnel lamp is slightly higher than that of LED reflective tunnel lamp when the installation angel is above 5°;The best installation angles of LED ceramic tunnel lamp and LED reflective tunnel lamp are 20°and 0°respectively.The related conclusions provide reference for lighting design for urban tunnel.
