Beibei Chongqing LED road lighting commissioning in October after the completion of energy-saving 70%

The Municipal Department of Beibei District of Chongqing city adopted reconstruction LED lights throughout the city, the city street lasted for LED 2 years of reconstruction completed in March this year, at present, the system is debugged, is expected in October after commissioning will realize the optimization of energy saving.

Effect of LED street lighting in Beibei District of Chongqing

Ming Daoliang, deputy director of the Beibei Municipal Administration Bureau, said: "most of the previous street lamps are 250W, 400W two specifications. We have calculated that a 400W street lights, from 7 at night to the next morning at 7, the power consumption of 12 hours need to be 5.64 degrees. "

After the installation of a single lamp intelligent controller, a specification for the LED 160W lamp can achieve the original 400W of the traditional lamp lighting effect, 12 hours only consume power of 1.92 degrees. Chongqing street lamp once electricity 0.53 yuan, a lamp to save about $1.97 a night.

Not only that, now the current energy-saving lamp, single lamp intelligent controller can control each lamp, lamp light output power changes from 0 to 100%, for example, 7 pm to, lamp power to 100%, the zero car are reduced, the power can be adjusted to 50%,. "Liang Liang said that this can achieve two energy-saving. This calculation, the actual power consumption of each LED lights is only 75% of the rated power. And a 160W of LED lights, 12 hours of electricity consumption of 1.44 kwh, a night to save electricity of about 4.2 degrees, equivalent to saving $2.226. A lamp to save 4.2 kwh a night, according to this calculation, a year can save electricity by 27 million 600 thousand degrees.
