Solar street pilot first cast Chongqing University city cost less than traditional street lights

Sunny summer mountain city, Jiangbei District recently, began the trial of solar street lamp. It is reported that there are a number of solar street lamp manufacturers to the newly established Chongqing City Lighting authority to report information, hope to promote large-scale solar street in chongqing. Chongqing street lamps are expected to take the lead in the use of solar energy and alternative energy as a secondary road, to ease tensions in the summer of Chongqing power.

LED light source instead of bulb

The light source solar lights use instead of the traditional high pressure sodium lamp, but LED (light emitting diode). LED uses the low voltage power supply, the power supply voltage is between 6-24V, is safer than using the high voltage power supply, especially suitable for the public place. Only when the LED energy consumption efficiency of incandescent lamp 1/5, that is to say, a 40 Watt LED lamps and 200 Watt high-pressure sodium lamp brightness, and because of its bright diffuse, pole is not high can achieve the same lighting effect.

City Lighting Management Bureau Chief Engineer Chen Guangming said, solar lights are basically the use of LED low voltage source, I also have Wuhu Jiangbei District manufacturers are solar streetlight pilot. At present, the world's largest producer of LED Hongkong zhenminglee group has to Chongqing to inspect and make detailed plans for the promotion of LED lights, solar lights ready.

Solar street lamp low cost

It is understood, one-time investment of solar streetlight is 5-8 times of high pressure sodium lamp, but the use of low cost. Ordinary street lamp high pressure sodium lamp each 400-800 yuan, to be changed every year, the electricity bill is generally more than 300 yuan a year, the greater the cost of laying online network. Solar street lights can save these costs. According to the Heshan silver rain lighting company estimates, the use of more than 5 years, the actual cost of solar street light is less than ordinary street lamps.

The first pilot University City

"Solar panels to collect in the cloudy energy is very low, and even if the sun is not clear, direct panels, the energy collected is not much, so the solar street lamp is the most suitable secondary roads and courtyards, unobstructed and the surrounding district. "Chen Guangming said, Chongqing's winter solar lights to illuminate the night, lit only at night, or turn bright intervals are feasible methods.

Reportedly, surrounded by open open campus of University City, is expected to be the first to use solar lights.
