摘要
Reasonable choice of light sources was the key to achieve energy-saving of tunnel lighting. Performance comparisons of light sources were completed, tunnel model was designed with lighting software-DIAlux based on characteristics and design demands of tunnel lighting. Simulation experiments for HPS (high pressure sodium) and LED (light-emitting diode) were made in the tunnel model, lighting effects of HPS and LED in each zone of the tunnel were analyzed, the results show that LED has higher lighting efficiency and can save more 40% power energy than HPS under the same lighting condition and the same road surface average-luminance, and LED has better road surface lighting effects and better color rendering than HPS.
