Tunnel lighting of LED into the mainstream

Departure from the "green light" concept and tunnel lighting features, led driver 120w lighting technology and energy-saving effects are reviewed.
Tunnels - Underground artificial construction, is a product of the development of human society, the crystallization of human wisdom. The earliest artificial trenches can be traced back to ancient times of war, as the transfer channels, shelter, and water diversion facilities. Modern trenches are widely used in the implementation of the prospecting, transportation and military, with the continuous development of modern transportation, the status of the tunnel in the transport and the importance of continuous improvement. The tunnel used to transport almost throughout the major cities in the world, the Seikan Tunnel, and the Anglo-French Channel Tunnel construction, human tunnel construction in the history of great initiative.

 With the rapid development of China's transport tunnels as part of the road has been considerable development, tunnel lighting is the basic component of the tunnel, the lighting quality of a direct impact on traffic safety, lighting energy consumption in the tunnel used in the costs accounted for a large proportion. LED tunnel lighting for its outstanding performance is becoming a mainstream light of today's world highways, tunnels and twinkle LED lamp.

The lighting is the basic building blocks of the tunnel, the quality of lighting is not only a direct impact on traffic safety, and energy consumption of lighting in the tunnel is the largest. . In China, electricity for lighting accounts for about 12% of the total electricity consumption, road lighting, electricity consumption accounted for about 20% -30% in the tunnel, in order to ensure driving safety and comfort, regardless of the day and night are can not do without lighting.

In the 1980s, with the rise of the tide of the global energy crisis and global environmental protection, environmental protection, energy conservation, the consensus of all mankind. The "green light" is the argument of the early 1990s the international savings on using electricity, protect the environment lighting system image. China's State Economic and Trade Commission, China's future LED light project started in November 1993, and in the national plan in 1996.

The tunnel is a special tubular structures, and Outside bright and spacious road vehicles through the tunnel from bright into the black hole, and from the black hole toward a bright process, for the light to dark or from dark to adapt to a process, in the process of adaptation, according to existing norms drivers is difficult to identify the object or objects inside the cave, the road, resulting in a visual and psychological barriers so that the traffic seems unsafe. The purpose of the tunnel lighting is by setting the lamps that adjust brightness to control the brightness of the transition changes in the human visual adaptation curve within, reduce the brightness of the dramatic changes to ensure traffic safety and comfort.

With the rapid development of China's road transportation construction, increasing the size and number of road tunnel construction, tunnel lighting has thus emerged, such as topband induction light, safety and other problems to be solved to achieve energy conservation, improve the lighting in the tunnel lighting effect and to ensure traffic safety and comfort, and can usually be considered in terms of brightness and uniformity of lighting, glare, stroboscopic effect.
