Abstract：In order to meet the rapid development of tunnel construction in recent years , LED light gradually highlights its application advantages in the tunnel lighting .The design tunnel is a segmented long tunnel.After considering the characteristics of its entrance form , driving speed, the hole direction, continuous tunnel brightness reduction , etc., and determining the tunnel illumination design standard , LED lamps are chosen for tunnel lighting .The selection and arrangement of LED lamps are calculated and analyzed in graphics .While taking advantage of the characteristics of LED light , non-polar control system is used to conduct the tunnel lighting dimming control .After the comparative analysis of LED and HPS ( High Pressure Sodium ) we can see that , although the initial investment of LED light is relatively high , the frequency of operation and maintenance and electricity costs are lower than that of traditional HPS .In the long run, LED lighting is a very energy-efficient green lighting , and the lighting control enables non-polar control , which fully embodies the advantages and benefits of LED lighting ' s usage in highway tunnel .It provides a new way of thinking to solve tunnel lighting .
