15 meters high how much solar energy lamp base

Used by common on the market at present LED light, the lamps and lanterns of basically has the following characteristics: 1, there is no light diffusing, guarantee the light efficiency; 2, LED lamps and lanterns has unique secondary optical design, will be the light of LED lamps and lanterns to the required lighting area, further improve the light

at present, the common on the market of LED light, the lamps and lanterns used mainly has the following characteristics: 1, light diffusion, ensure the lighting efficiency; 2. Light emitting diode lamps and lanterns has unique secondary optical design, the light emitting diode lamps and lanterns light to stay lighting area, further improve the efficiency of lighting, achieve the goal of energy saving; 4. The brightness of the LED lamp is very high, from the perspective of visual psychology, to achieve the same brightness. Compared with high pressure sodium lamp, led street light illumination can reduce more than 20% on average ( Refer to the road lighting standards) ； 5. Leds light attenuation is small, less than 3% a year, 10 years still can satisfy the requirement of road lighting. 6. Light emitting diode is low voltage devices, drive a single light-emitting diode voltage is safe. Series of products in each power of 1 watt leds, therefore safer than using high voltage power supply, especially in public places. 7. Long service life: can use more than 50000 hours.
