Study on Night Lighting Environment of Highway Tunnels

MA Fei;WU Mengjun;DING Hao;WANG Qian;  
With the increasing of road tunnels year by year,the quality of tunnel lighting is getting more and more attention.By means of numerical simulation,the night lighting conditions of high-voltage sodium lamp and LED lamp in different lamp layout were compared,and the night lighting effects of the two kinds under different brightness adjustment modes were analyzed.The results have showed that the dimming mode with loop control will reduce the evenness of pavement lighting; yet the evenness under stepless dimming mode has nothing to do with the output ratio of luminous flux,under which pavement lighting can maintain a good evenness.The conclusion can provide important reference for expressway tunnel night lighting design and operation control.
