Chongqing first solar street lamps

LED light source instead of the light bulb use solar street lamps light source is not a traditional high pressure sodium lamp bulb, but LED Light emitting diode) 。 LED use the low voltage power supply, power supply voltage in 6 - Between 24 v, safer than using high voltage power supply, especially suitable for public places.

the LED light source to replace the bulb use solar street lamps light source is not a traditional high pressure sodium lamp bulbs, LED lights, but LED Light emitting diode) 。 LED use the low voltage power supply, power supply voltage in 6 - Between 24 v, safer than using high voltage power supply, especially suitable for public places. LED energy consumption is only 1/5 of incandescent lamp with light efficiency, that is, a 40 watts of LED lights and 200 w high pressure sodium lamp brightness, and due to its invasive good light, light pole is not work to achieve the same lighting effect. Administration of urban lighting, said Chen gm general solar LED street lamp basically is to use the low voltage source, a village in the north of the zhuhai have wuhu factory is the system of solar street light. At present, the world's largest producer of LED Hong Kong really bright group has come to chongqing to investigate and develop detailed plans for promotion of LED street lamp, solar street light on the horizon. Low cost according to solar street lamps, solar street lamps to invest is 5 - high pressure sodium lamp Eight times, but the cost is very low.
