led tunnel light tunnel is a lamp, and it is applied to the tunnel, workshop, large warehouses, stadiums, and all kinds of metallurgical plant, construction, etc. Place large area flood lighting, ideal for the urban landscape, billboards, building facades for landscape lighting. With the rapid development of China's road construction, highway construction scale and the number of tunnels is also growing, tunnel lighting has thus emerged such as energy, security and other problems to be solved, with the LED light source technology matures, domestic lighting industry has also carried out research and practical application in highway tunnel LED lighting applications, therefore, combined with advanced control in tunnel lighting, high light efficiency, good stability, long life light source will be a demand for a new generation and trends. Feature led tunnel lamp is a light efficiency energy saving lamps, use light-emitting diodes (LED) as the light source body, high luminous efficiency, long life, can be realized with different mirror multipurpose lighting; and by the softening process, not people blinding or other discomfort. Ballast selection overheat protection technology to ensure lamp life. Imports of high-purity specular anodized aluminum reflector material made by precise optical design, power factor greater than 0.9, Reflective, high efficiency, good transparency, energy conservation and environmental protection. LED tunnel lighting and contrast conventional LED light source is a solid state semiconductor devices, which can be converted directly into electricity to light, compared to traditional road tunnel lighting (sodium, metal halide, etc.), LED light source has the following advantages: (1) light is small: if in good thermal conditions, LED front 10000h Masamitsu bad as before 10000h light decline of 3% to 10%, before 50000h basic 30%, far lower than the ordinary road lighting, emitting more stable. (2) high color: LED color generally about 70 ~ 80, higher if the words of three-color phosphor; high pressure sodium lamp is generally 20 to 35, lower low-pressure sodium lamp, so even if the brightness of conventional light sources higher than the LED, but the visual effect is worse than the LED, "not the brightest, but see most clearly," this should be a direction LED light source application development. (3) life: LED life span than the general road tunnel lighting, now generally higher than 50000H. (4) Price: LED lamp Although the price is higher than traditional lighting high, but with the manufacturing technology matures, its current price continue to decline sharply, the high and low pressure sodium lamp price is generally set at 2,000 yuan, while its auxiliary cables, etc. price is higher than the LED cable and other expenses. In addition, LED also has a maintenance factor, good safety performance, no flicker and energy saving advantages. Case
