| 摘 要： | 探究灯具距高比对隧道照明质量的影响，从而为隧道布灯的优化提供理论依据。利用DIALux分别在距高比为1.5、2.0、2.5下对14种不同的安装角度进行照明模拟试验，每种距高比模拟5组参数，输出各工况的照明质量参数。建立不同距高比下的路面平均照度、路面照度总均匀度、路面中线照度纵向均匀度随安装角度的关系曲线图。结果表明:同等条件下，三大照明质量指标均随距高比的减小而增大；无论距高比为多少，随着安装角度的增加，三大照明质量指标先期变化相对缓慢，随后急剧减小，但是开始骤减时对应的安装角度存在显著差异；实际工程中，在满足规范指标的前提下，为了节省照明成本，应尽量减小灯具用量，选择最优的组合方式。

| Abstract: | In order to study the influence of the spacing-to-mounting-height ratio of the luminaire on the tunnel lighting quality, the research was conducted in order to provide a theoretical basis for the optimization of the tunnel lamp distribution. DIALux was used to carry out lighting simulation tests at 14 different installation angles with the spacing-to-mounting-height ratio of 1.5, 2.0 and 2.5 respectively, and each of them includes five sets of parameters, outputting lighting quality parameters of each working condition. Graphs of the relationship between the average road surface illuminance, the overall uniformity of road surface illuminance and the longitudinal uniformity of road surface illuminance with the installation angle were established under different spacing-to-mounting-height ratios. Results show that under the same conditions, the three lighting quality indicators increase with the decrease of the spacing-to-mounting-height ratio; no matter what the spacing-to-mounting-height ratio is, with the increase of the installation angle, the three major lighting quality indicators firstly change relatively slowly and then decreases sharply, but there is a significant difference in the corresponding installation angle when starting to decrease sharply. In practice, under the premise of meeting the standard index, the number of lamps should be reduced as much as possible in order to save the lighting cost, and the optimal combination mode should be selected. |
