Study On Energy-saving Technology Of Highway Tunnel Lighting System In Yunnan Province

With the rapid development and construction of Highway, the highway tunnel track in use is getting more and more longer, the tunnel illumination is regarded highly. At the same time, the cost of the highway tunnel's construction and the operation are high, particularly, the energy consumption of in the operation process is huge, and, tunnel illuminators energy consumption cost account for most of the tunnel cost. Using the tunnel energy conservation lighting techniques in the highway tunnel construction can save the electrical energy in possible, and lessen business cost, and raise the highway tunnel's economic efficiency and the social efficiency.The article first describes the highway tunnel illumination sector division and lighting standards, and analyze the tradition and new model illuminant of the vehicular tunnel lamp, and narrate the light and luminaires special requirements and standards, and do research the principle, way and systematic formation of tunnel illumination controls. Secondly, to the tunnel illumination vision characteristic, influencing factor of the tunnel illumination quality of driver vision characteristic and the tunnel illumination energy conservation present situation are explained ,carried on the explanation, the research obtain the highway tunnel illumination energy conservation strategy. Once more, according to the functional principle and the principle of energy conservation for tunnel lighting design and optimization, the benefit assessment can estimate in three aspects, for example , the economic effect, environmental protection and social benefits. Finally, take the Guangnan-Yanshan highway tunnel as the example, explains the application of the tunnel illumination energy conservation.Tunnel illumination energy conservation technology research, not only provides driving environment, moreover to reduce the operation cost, reduce the energy consumption and have the important meaning.
