1. Foreign development status of

in the 1950 s, has been carrying out the research of highway tunnel lighting technology abroad, it has been more than 60 years. Many countries after continuous exploration and innovation, the highway tunnel lighting technology already quite mature. When the time development to modern, the tunnel lighting system of developed country gradually from the aspects of high-tech intelligence to sustainable human development. Only eastern European countries, highway tunnel has been generally start using & other; The secondary light distribution & throughout; And & other Back lighting & throughout; Technology. At the same time make full use of the light source, saving electric energy and lighting tools such as resources. On the lighting tool selection, Europe and the United States and other developed countries abandon the high pressure sodium lamp, switch to optical fiber tunnel lights, electronic induction electrodeless lamp and new equipment.

　　2. Domestic development status of

domestic tunnel lighting system development started relatively late, although the current era, our country highway tunnel development momentum is very rapidly, but still can't compare with foreign mature technology and ideas. Gap not only in the technology and experience, and basic engineering construction is also a certain deficiencies. In January 2000 in our country promulgated the 'specification for design of highway tunnel ventilation and lighting, the detailed rules for tunnel light classification and grade of the light source, the general regularity and lamps and lanterns decorate etc. But due to the electrical energy resource waste is very serious in recent years, relevant departments have begun to wide public concern over the tunnel lighting system energy conservation design problems. At the same time, the research theory in our country in the highway tunnel construction with the help of the corresponding energy saving design, such as tunnel, hebei simatai tunnel hope guangdong, anhui has successively, such as former home mountain tunnel will LED lights and promise the dimming technology used in highway tunnel lighting.

　　3. Development trend of highway tunnel lighting

the highway tunnel lighting quality affects the driving safety, over the years, the highway tunnel builders have been the lighting quality as the core content of engineering design and research emphasis, but neglected the energy waste problem. Highway tunnel lighting system at the present stage in China, therefore, on the premise of guarantee the safety, energy saving design is the inevitable requirement of highway tunnel lighting system development, humanity, economization, scientific is lighting technology development and the inevitable trend of social development. 【 The above content released by solar street lamps factory finishing for you 】
