Led tunnel light is a kind of tunnel light. And led tunnel light is usually applied to tunnel, workshop, large warehouses, stadiums, metallurgy and all kinds of manufacturing, engineering, construction and other places with large flood lighting area. Led tunnel light also is suitable for beautification lighting for urban landscape, billboard and building facade. With the rapid development of our country road traffic construction, the construction scale and quantity of highway tunnel are becoming bigger and bigger. The tunnel light also appeared problems to be solved, such as energy saving, security and so on. With the maturing development of the LED tunnel light source technology, LED lighting industry experts makes study of the application of led tunnel light in the highway tunnel light. Therefore, combined with advanced control mode in the tunnel light, using a new generation of light source with high photosynthetic efficiency, good stability and long service life will become a new demand and trend.
The features of LED tunnel light:
LED tunnel light is a kind of energy-saving lighting lamps and lanterns, which choose the light emitting diode (led) as a light source, whose features are high luminous efficiency and long life. With different mirrors, LED tunnel light can realize multi-purpose lighting. And because of the diffusion process of light, LED tunnel light won't make the person produce dazzle or other unwell reaction. Ballast applies overheating protection technology to ensure the service life of LED tunnel light.
Compared with traditional tunnel light, LED tunnel light is a solid-state semiconductor devices, which can change electricity directly into light. Compared to the traditional road tunnel lighting source (sodium lamp, metal halide lamp, etc.), LED tunnel light source has the following advantages:
(1)Small Lumens Depreciation: in the case of good cooling condition, the lumens depreciation of LED tunnel light is 3% -10% in the first 10000 hours; in the first 50000 hours the lumens depreciation of LED tunnel light is 30%, far less than the ordinary road lighting. LED tunnel light emits more stably.
(2)High Color Rendering: generally the color rendering of LED tunnel light is about 7 0 ~ 8 0; while the color rendering of common high pressure sodium lamp is 2 0 to 35, and low pressure sodium lamp is lower. So even if the traditional light source is brighter than that of the LED tunnel light, the visual effect is worse than LED tunnel light’s. "Not the brightest, but the most clear for see" should be a direction of the development of LED light source.
(3)Service life: the life of the LED tunnel light is longer than general road tunnel light’s. The service life of LED tunnel light usually is more than 50000 hours.
(4)Price:the price of LED tunnel light is higher than traditional lighting lamps and lanterns, but with the maturity of manufacturing technology, the price will have a dramatic drop. The current price of high and low voltage sodium lamp is US$ 200 or so.
In addition, the LED tunnel light also has advantages of high coefficient of maintenance, good safety performance, no stroboscopic, and energy conservation and environmental protection
