| 摘 要： | 从二车道公路隧道中间段照明的关键参数入手,依靠1∶1实体隧道开展对比实验,研究在中央布灯情况下路面平均照度Eav、路面亮度总均匀度U0、路面中线亮度纵向均匀度U1以及灯具利用系数η在随布灯高度变化时的影响。实验表明,在中央布灯情况下,随着灯具的布设增高路面平均照度Eav随之下降;而路面亮度总均匀度U0、路面中线亮度纵向均匀度U1随之变大;灯具利用系数η也随之变小。

| Abstract: | Based on the key parameters of illumination in the middle of the two-lane highway tunnel and the 1∶1 solid tunnel to make a comparative experiment,this paper tries to analyze the influence of the average illumination level on the road Eav,the total average level of the brightness on the road U0,the longitudinal average level of the brightness on the central line of the road U1,and the utilization coefficient of lighting lanterns η caused by the change of the height of the road lighting installation.The experiment shows that under the condition of installing the road lighting lantern in the middle of the tunnel,as the height of the road lighting installation increases,the average illumination level on the road Eav decreases,the total average level of the brightness on the road U0 and the longitudinal average level of the brightness on the central line of the road U1,increase,and the utilization coefficient of lighting lanterns η decreases. |
