LED tunnel light is a kind of tunnel light. It is widely used in today's society. It is suitable for tunnels, workshops, large warehouses, venues, metallurgy and various factories, engineering construction and other on-site large-area full-light lighting. LED tunnel lights are the most Suitable for urban landscape, billboards, building facade landscape lighting.

(1) LED tunnel lights consume power and save energy. Compared with traditional high-pressure sodium lamps, they can save more than 40% of energy. (2) The LED tunnel light has a long life. Under the ideal state of 50000H, the life of the LED tunnel light, high pressure sodium lamp and fluorescent tube is only 10000H.

(3) LED tunnel lights have high reliability, low daily maintenance and maintenance costs, and the average trouble-free working time (m can reach 30,000 hours, while the average trouble-free working time of high-pressure sodium lamps and fluorescent tubes is less than 10,000 hours.

(4) Reduce the construction cost of power distribution system (cables, transformers, distribution boxes, bridges, etc.). For long tunnels, long-distance power supply, cables, and power distribution facilities, the cost of LED tunnel lights is particularly large. Electricity can greatly reduce the investment in cables and distribution equipment.

(5) The LED tunnel light can be started instantly, the brightness of the LED tunnel light is easy to adjust, has the characteristics of no stroboscopic, and a large starting voltage range, which can realize a variety of energy-saving methods, such as intelligent adjustment of illumination according to road and tunnel traffic.

(6) High-pressure sodium lamps, fluorescent lamps, and electrodeless lamps contain chemical pollutants such as mercury and lead, while the LED tunnel light source does not contain chemical pollutants and is a green light source.

LED tunnel light is a kind of light-efficiency energy-saving lamp. Light-emitting diode (LED) is used as the light source, which has high light efficiency and long life. It can realize multi-purpose lighting with different mirror surfaces; the ballast adopts overheating protection technology, and the LED tunnel light guarantees Lamp life. Imported high-purity aluminum anodized material is used as the reflector and through precise distribution design, the power factor is greater than 0.9, the reflection efficiency is high, the light transmittance is good, energy saving and environmental protection. Comparison of LED and traditional tunnel lighting sources LED is a solid-state semiconductor device. Compared with traditional road tunnel lighting sources (sodium lamps, metal halide lamps, etc.), it can directly convert electricity into light,

(1) Small light decay: if the heat dissipation conditions are good, the positive light decay of the LED in the first 10000h is 3%10%, and the light decay of the LED tunnel light is basically 30% in the first 50000h, which is much lower than the positive light decay of ordinary road lighting. Light source, the light is more stable.

(2) High color rendering: Generally, the color rendering of LEDs is about a few dollars, and if three phosphors are used, it is higher; the general high-pressure sodium lamp is only a few dollars, and the low-pressure sodium lamp, so although the brightness of the traditional light source is higher than that of the LED, the visual effect of the LED is higher. The effect, "not the brightest, but the clearest" should be the development direction of LED light source applications.

(3) Lifespan: LED lifespan is higher than that of general road tunnel light sources, and now LED tunnel lights are generally higher than 50000H.

(4) Price: Although the price of LED lights is higher than that of traditional lighting, with the maturity of manufacturing technology, the price is now greatly reduced. The general price of Zhongheng, high and low pressure sodium lamps is 2,000 yuan, LED tunnel lights and their cables The price of other accessories is higher than the cost of LED cables.

In addition, LED also has the advantages of high maintenance factor, good safety performance, no flicker, energy saving and environmental protection. It is with this series of advantages that LED tunnel lights have been widely used in today's society.
