Study on lamp-layout scheme of highway tunnel lighting based on DIALux

Abstract

Aiming at the traffic safety and comfort issues of the tunnel lighting system,In this paper, taking the case of ChiBai Tunnel in Tonghua of Jilin Province and HeDa Expressway ShiDao-YangCha tunnel,different installation methods,installation height,installation angle,and different combination of lighting power and the installation space with the same power in unit length are simulated by using DIALux software.Through the comparison and analysis of average road surface illumination and the evenness data obtained from two tunnel simulation tests,it can find out the best scheme of the tunnel lighting,to provide reference for reasonable design and configuration of tunnel lighting.
