摘要
隧道照明系统对驾驶员的行车作业起着至关重要的作用,照明灯具出现损坏甚至失效,将对行车安全造成一定程度的影响。为此,本文对隧道照明系统灯具的不同失效形式作出相关研究,采用照明分析软件DIALux对隧道内单灯具、双灯具以及多灯具失效等不同情况进行了数值模拟,结合相关照明参数指标如路面平均照度、路面平均亮度、路面亮度总均匀度和路面亮度纵向均匀度等定量研究灯具的失效对照明质量的影响。研究结果得出,单灯失效时对照明质量影响很小,各参数指标均满足规范规定及照明需求,双灯失效时对照明质量有较大程度的影响,不同工况的同一参数指标之间波动较大,个别工况参数指标已不满足规范规定,需根据实际情况进行判断。多灯失效(包含连续多灯)时,照明质量极差,严重威胁行车安全,极易引发交通事故。
The tunnel lighting system plays a vital role in the driving operation of the driver.Damage or even failure of the lighting fixtures will have a certain degree of impact on driving safety.To this end,this article makes relevant researches on the different failure modes of tunnel lighting system lamps.The lighting analysis software DIALux4.13 is used to numerically simulate the failure of single lamps,double lamps and multiple lamps in the tunnel.Combined with relevant lighting parameters,such as average road surface illuminance,the average road surface luminance,overall uniformity of road surface luminance,and longitudinal uniformity of road surface luminance,the effect of lamp failure on lighting quality is quantitatively studied.The research results show that when a single lamp fails,it has little effect on the lighting quality,and each parameter index meets the specification and lighting requirements.When the double lamp fails,it has a greater impact on the lighting quality.The same parameter index under different working conditions The fluctuation is large,and the parameters of individual working conditions have not met the specifications,and judgments need to be made based on actual conditions.When multiple lights fail(including continuous multiple lights),the lighting quality is extremely poor,which seriously threatens driving safety and easily causes traffic accidents.
