Xi'an: 130 thousand LED lights adorn the ancient city of night electricity savings of nearly 30 million

Under the shadow of the night, take the South Street, many people will be attracted by the simple chic pedestrian lighting. These lights are new energy-saving LED energy-saving lamps. In recent years, Xi'an has been using the 130 thousand landscape LED lights a total of nearly 30 million yuan to save electricity.

130 thousand LED lamps installed

The city has a total of 420 thousand city lights and landscape lighting lamps (including the districts and counties), respectively, by the Xi'an City Lighting Management Office, the high tech management committee, the CMC and other management units. Among them, the city lighting management department under the jurisdiction of a total of 1323 sections of urban lighting, urban lighting lamp number of 241767.

According to Zheng Donglai, director of urban lighting management, LED lights are low energy sources. In accordance with the goal of energy saving and emission reduction, since the start in 2002, as of the end of last year, the city installed a total of 130 thousand LED lighting lamps, mainly distributed in a ring, the second ring road and pedestrian bridges and other areas.

It is reported that the only north-south axis transformation during the last year, the city in the city (north gate and South Gate) and north gate section includes South Gate winding path bends, installation of antique style LED lights 82 base 164 sets, 200 sets of antique garden lights sidewalk installation.

Save electricity nearly 30 million yuan

At present, the main use of LED single lamp power is 8W, equivalent to 40W energy-saving lamp brightness. Through its effective energy-saving effect, a rough estimate of a total of nearly 30 million yuan a year to save electricity bills.

How to effectively realize the low efficiency of urban lighting energy consumption? Zheng Donglai said, in addition to the promotion of the use of LED lamps, the current management also actively implement the city's lighting automation control. At present, the city's 95% street lamps have been opened automatically closed, a total of street lights to monitor the 229679. 2002 to the end of 2008 to shorten the total lighting time of 25550 minutes, saving electricity expenditure of $6 million 560 thousand.

The city lighting management department have special substation 446 units, installed Saver 181, the remaining 265 special substation, Saver installation work is being gradually implemented, all the installation is complete, every year at least save electricity 33 million 270 thousand yuan.

To promote the main road

Zheng Donglai said that the current LED lighting is mainly for landscape areas and sidewalk lighting, the city will also vigorously promote the use of LED lamps. The motor vehicle lighting required on the road to high current management departments have and production enterprises, the high-power LED lamp used in the pilot Wenjing road individual sections, to test its effect in road functional lighting, once they meet the lighting requirements, will be applied in the other way in the future.

It is understood that last year, the Ministry of science and technology has officially approved Xi'an as the country's Ten City million LED lighting application engineering pilot cities. It will also provide a better environment for the city to actively promote and use green, efficient energy-saving lamps and light sources. LED is related to the English light emitting diode (light-emitting diode), its basic structure is a light-emitting semiconductor materials. Using a LED lamp voltage in 624V, safer than the use of high voltage power supply, especially suitable for public places. Incandescent lamp LED lamp with light energy efficiency by 80%.
