1 Introduction: With the rapid development of China's road construction, building size and the number of road tunnel is also growing, tunnel lighting has thus emerged as energy, security and other problems to be solved, with the growing LED light source technology mature, domestic lighting industry has also carried out research and practical application in highway tunnel LED lighting applications, therefore, combined with advanced control mode in the tunnel lighting, the use of high efficiency, good stability, long life will become a new generation of light Demand and Trends 2 Features: led tunnel light is a light efficiency energy saving lamps, use light-emitting diodes (LED) as a light source body, high luminous efficiency, long life, can be achieved with different mirror versatile lighting; and by softened, does not engender glare or other discomfort. Ballast selection overheating protection technology to ensure lamp life. Imports of high-purity materials made of anodized aluminum mirror reflector and through precise optical design, power factor greater than 0.9, reflective, high efficiency, good transparency, energy saving 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 the 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 for Masamitsu failure, before the light fades 10000h 3% to 10%, the first basic 50000h 30%, far lower than the ordinary road lighting, light more stable. (2) high color: General LED color is about 70 ~ 80, higher if the words of three-color phosphor; HPS is generally 20 to 35, lower pressure sodium, 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 to 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 high price than traditional lighting, but with the manufacturing technology matures, its prices are now constantly dropped, the high and low pressure sodium lamps are generally set prices at around 1,800 yuan, while its cable and other accessories 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.
