Led turn on the tunnel light, connect the power supply, and then turn on the light system device. Why not turn on the light?
Nevertheless, the forum pointed out that development of 2010LED application technology and marketing professor at Chongqing University, Chongqing city LED lighting alliance Secretary General Chen Weimin held in Shenzhen in September 6th, the LED tunnel domestic lighting applications there are still some unsatisfactory places.
China is the country with the largest number of tunnels in the world. In recent ten years, the tunnel lighting has developed rapidly. The pilot project of "ten cities and ten thousand lights" launched in 2009 has accelerated the application of LED in tunnel lighting. For a time, Shanghai, Guangdong, Fujian, Zhejiang, Chongqing and other 11 provinces and cities, launched dozens of nearly 100 kilometers of LED tunnel lighting pilot.
Compared with outdoor lighting, the tunnel lighting is relatively constant temperature and humidity, and the air flow characteristics of the automobile driving space also make it better for the cooling conditions, but the construction and maintenance are difficult, and the service life is longer. LED is one of the best application fields for tunnel lighting because it has the most remarkable energy-saving effect and the most advantages of directional dense lighting.
The tunnel is a narrow, confined space, and the hole produces an uncomfortable black hole effect. The hole has a daylight effect, and at night it is just the opposite. The driver enters the tunnel unavoidably to have certain psychological suppression feeling, therefore the tunnel illumination applies in is different from other illumination special occasions. This requires that the tunnel lights require intensive directional lighting, and that the lamps have larger power, larger quantities, and 24 hours of uninterrupted lighting.
1, check the power supply line voltage is normal2. Check the dimming system itself is a problem, wiring is normal3, check the LED lamp itself whether there is a problem, the wiring is normalIf there is a problem in the above aspects, the LED light will not turn on.
