    A tunnel is a kind of underground space that consists of a semi-closed structure. Because of its special structure, the tunnel can not be direct sunlight, during the day also need lighting. Lighting system is one of the most important facilities in the modern tunnel project, and the tunnel lighting is put into use, the lighting system is in the long-term working condition.
 
    The origin of the tunnel can be traced back to the Spring and Autumn Period, Qin cut the world's first artificial tunnel "praise chute." Historical records of the cloud: "plank road thousands of miles, through the Shu Han, so that the world are afraid of Qin." At that time the tunnel lighting is a torch, very simple and very inconvenient. In the modern period, with the development of industrialization, tunnel traffic gradually increased, tunnel lighting has gradually developed, in the mid-nineteenth century, tunnel lighting to kerosene, gas-based, until the end of the nineteenth century, the light gradually applied to the tunnel lighting The

Simple tunnel lighting era
 
    In the early nineties of the last century, few tunnels in our country, tunnel lighting facilities is out of the question, most of the tunnels on the road without lighting or only a few lights, lighting quality is very low, then the tunnel lighting only stay in the simple Of the lighting needs only.
 
     In the contemporary, with the continuous innovation of technology, the development of tunnel lighting has made great progress. Even in the era of simple lighting, tunnel lighting has experienced from the incandescent, fluorescent, high pressure mercury lamp, low pressure sodium lamp, high pressure sodium lamp development process. Tunnel lighting in the light efficiency, luminous flux, life, light color and color and other aspects of continuous breakthroughs, to create a better tunnel lighting environment.
 
Intelligent tunnel lighting era
 
    Into the twenty-first century, LED lighting technology has become increasingly strong, LED lighting has gradually occupied most of the tunnel lighting market. LED light source with high luminous efficiency, high color coefficient, long life, energy efficient, ultra-low power consumption characteristics, and LED lights have a more perfect dimming function, according to day, night and traffic size and other factors at any time to change the tunnel Lighting level, through the integration of WiFi, ZigBee and other network technology, LED lighting for the tunnel lighting ushered in the era of intelligent lighting.
 
    2007 domestic LED road, tunnel lighting market began to form. At first five years, due to many manufacturers ignore the LED lighting problems, has caused LED road, tunnel and other lighting project failure rate as high as 90% or more, misleading the LED lighting technology "is not mature enough to wait and see development trend" public opinion. But at the same time, Shanghai think twice with their original heat, lighting layout and other technologies, developed the completion of the 148 LED road, tunnel lighting projects, provided by the 250,000 high-power LED lamps are all stable operation. Among them, China's first LED tunnel lighting project - Jiangxi King Eagle high-speed tunnel LED lighting project, the Ministry of Transportation as energy-saving emission reduction demonstration project; the same use of Shanghai think of LED lighting project - Fujian Nanhui highway tunnel , Was the Development and Reform Commission, Ministry of Finance, Ministry of Transport as a highway tunnel LED lighting national demonstration project.

    Tunnel lighting intelligent control system in addition to the lighting needs of different sections, the use of reasonable tunnel illumination illumination distribution, but also to support a variety of intelligent dimming methods, such as: as a tunnel lighting lights, near the entrance and exit lights The brightness should be closer to the normal outdoor light, from both ends to the middle of the gradual decline to reduce the "black hole, white hole effect" to enhance traffic safety; at the same time according to time, season, weather, etc. automatically adjust the brightness to the appropriate location function , Lighting system built-in different scene mode, to achieve intelligent management to ensure traffic safety. In this regard, Shanghai Sisi construction of Shaanxi oak small tunnel intelligent lighting project, was named the national demonstration project.

     In addition, Shanghai think twice of the LED application products and intelligent control system is also used in Yunnan Dili Expressway tunnel, Chongqing Zhangjiashan tunnel, Hunan Liangshuijing tunnel, Shanghai Dalian Road tunnel, Beijing Jingcheng high-speed, Yunnan Pu Xuan Road tunnel, G85 Yu Kun high-speed Ma Zhao line tunnel and Hong Kong-Zhuhai-Macao Bridge deep-sea tunnels built or under construction of large-scale tunnel project.
 
     In recent years, with the acceleration of urbanization process, people pay more and more attention to the safety and comfort of road traffic, the tunnel lighting intelligent control technology requirements are getting higher and higher; and with the new technology, the continuous development of new technologies , Tunnel lighting intelligent control technology will also be "more energy efficient, more comprehensive, more comfortable" direction.
