The high pressure sodium lamp is adopted as the light source in most of the current tunnel,however, the high pressure sodium has many deficiencies, including in the form of radiation, the color, the visual sensitivity characteristics, power specifications, brightness control and so on, the LED tunnel lighting with its excellent performance especially high brightness control lines overcome the disadvantages of high-pressure sodium lamps, LED tunnel lighting is becoming the mainstream of the world's lighting, the State has introduced the new initiatives of "Ten City, ten thousand," which brings unprecedented opportunities to develop LED tunnel lights for semiconductor lighting. LED light-emitting diode is the semiconductor light-emitting technology, the LED firstly developed can emit red light and was used as the indicator for electronic devices. With the development of technology, LED lights can emit various of colors lights now and is widely used in many types of industries, the main application markets including traditional display and lights markets, backlight market, street lamps, tunnel lights, automotive lighting market, outdoor landscape lighting and interior lighting market, specialty. LED tunnel lamps have a unique advantage in lighting market 1, LED tunnel light has low power consumption, compared with traditional high pressure sodium lamp, energy saving is more than 30% 2, LED tunnel light has long life, it has 100,000 H in the ideal state, while the high-pressure sodium lamps and fluorescent tube life is only 10 000 -3 million H 3, LED tunnel lights has high reliability, routine maintenance and repair costs is low, mean time between failures (MTBF) is up to 20,000 h, while, the average time between failures of the high-pressure sodium lamps and fluorescent tubes is less than 10,000 H 4, reducing the construction costs of the power distribution system (cables, transformers, power distribution boxes, trays, etc.), for remote power supply in long tunnels,cables and distribution facilities account for particular large share of the cost ratio, LED tunnel lights because of saving can greatly reduce the investments of cables and distribution equipment and others. 5, LED tunnel lights can achieve instant start, which is help for adjusting brightness, it has no glare and the range of start voltage is wide, etc., can be achieved a variety of energy-saving methods such as intelligently adjust brightness according to roads, tunnels traffic etc. 6, the high-pressure sodium lamps, fluorescent lamps, lamp contain mercury, lead, chemical pollutants, but LED tunnel light source without chemical polluting substances,it is a green light source Lead lighting insists in using high quality LED chip and driver and radiator material to produce energy saving LED tunnel lights, which is able to adapt to the closed and dim light in the tunnel, you can log www.lead-lighting.com/products/bid32-1.htm to know about more LED tunnel lights or back to Home for other options LED illumination.
