隧道连续照明效能分析研究

针对隧道内传统点式布设照明存在的视觉均匀度不佳和诱导性差等问题,提出一种连续照明的方法,并用Dialux光学分析软件对隧道连续照明进行数值仿真,分析其照明环境的舒适性和能耗性。基于仿真给出的配光曲线,研究得出:1)连续照明时,相比点式照明其路面亮度的总均匀度和纵向均匀度最高分别可提升45%和16.3%,且连续照明光环境视觉诱导性好;2)连续照明GR眩光方面无明显突出特点,且能满足规范要求;3)路面相同亮度等级下,连续照明比点式照明需求的光通量要高、比点式照明中的对称型配光和偏光型配光分别高出2%和14.7%,照明节能效果不明显。

Analysis of Tunnel Continuous Lighting Efficiency

Aiming at the problems of poor visual uniformity and poor visual inductivity in traditional tunnel spacing layout lighting,a continuous illumination method is proposed.In this paper,Dialux optical analysis software is used to numerically simulate the continuous illumination of the tunnel,to analyze and evaluate the comfort and lighting energy consumption of the lighting environment.It is concluded that the total uniformity and longitudinal uniformity of continuous illumination compared with traditional discontinuous illumination can be increased by 45%and 16.3%respectively based on light distribution curve,and the visual illumination of continuous illumination is good;continuous lighting GR glare has no obvious features,and can meet the requirements of the specifications.In terms of lighting energy consumption,continuous lighting requires higher luminous flux than discontinuous lighting.The continuous lighting is 2%and 14.7%higher than the symmetrical light distribution and the polarized light distribution in the discontinuous lighting respectively,and the energy saving of the lighting is not obvious.
