The end of intelligent lighting LED save money does not save the history

Recently, intelligent adjustment of highway tunnel LED jointly developed by the Hefei light source glow Electronics Co. Ltd and Guizhou Expressway Development Corporation light control technology and complete sets of equipment is successfully applied to the Guizhou gllon Xia Rong highway tunnel. By the national traffic safety facilities quality supervision and inspection center on-site 48h test, the left hole LED intelligent stepless dimming lighting system is more than the right hole LED grading lighting system energy saving 34.7%. The results show that the use of LED light control and intelligent lighting system than the constant brightness of the LED lamp has a greater energy saving advantages. LED intelligent highway tunnel lighting system sets of key technologies in the successful application of gllon tunnel, completely subvert the traditional mode of opening and closing the lighting lamps only, by adjusting the lamp brightness, greatly reduces the energy consumption of lighting industry, lighting according to the needs of the pursuit of long-term goal.

According to experts, the lamp brightness when in use will continue to decay, so it must be pre brightness increased by about 50% in the highway tunnel and city road lighting design (which is about 0.65 of the value maintenance coefficient divided by brightness standard), so that the brightness of light attenuation can ensure the surface brightness in the above standard. This makes the lamps in the use of the process and before the waste are in the state of excessive lighting, serious waste of electricity. Although the maintenance factor of extending the replacement cycle of the light source, but also the power consumption of the electric tiger. Especially in the middle of the night when the vehicle is less, the energy waste is as high as 67%. The LED intelligent lighting, can be through the fine brightness adjustment, avoid the waste of production, maintenance coefficient is no longer a tiger.

According to the analysis of the relevant literature, LED intelligent stepless dimming lights if the replacement of high pressure sodium lamp, usually can save more than 60%; if applied to urban road lighting, LED lights will be more than 40% energy saving. Compared with the LED lamp, the utility model not only saves energy, but also reduces the working temperature of the lamp, and prolongs the service life of the lamp. In terms of investment, compared with the high-pressure sodium lamp, just three years or so, you can increase the recovery of all the proceeds through the energy saving. The intelligent dimming system and LED lighting lamps compared to lamp life is 3 times of the same type of lamps, and used for highway tunnel cable investment can be reduced more than 30%, the system can save energy and money industry desire.
