Solar street lamps retrofitting standards

Solar street lamps retrofitting standards. Solar street lamps standard generally is: 1. Light conversion rate 17%, Each square solar power is 1000 w, practice using the power of 170 w) 2. Street lamp lens data to improve the optical data, the market at present through rate is 93%, heat-resistant - 38 - + 90 degrees



solar street light retrofitting standards. The solar street lamps Solar street light is a crystalline silicon solar battery power supply, valve control type sealed and maintenance-free battery ( Gel battery) Store electricity, super bright LED as light source, lamps and lanterns and controlled by the intelligent charging and discharging controller, is used to instead of the traditional public power lighting lamps. 】 Standard is commonly:

1. Light conversion rate 17%, Each square solar power is 1000 w, practice using the power of 170 w)

　　2. Current market street lamp lens data to improve the optical data, transmittance & ge; 93%, heat-resistant - 38 - + 90 degrees.

　　3. Solar street lamp lens, lens is mainly used for solar street lamps, light as the rectangle, material is PMMA 【 PMMA is also called the acrylic or inferior strength, acrylic (from English Acrylic plastic) 。 】 Optical materials, transmittance & ge; 93%, heat-resistant - 38 - + 90 degrees, resistance to UV ultraviolet ` etiolation rate for 30000 hours without change, etc. ,

4. The road illumination uniformity, 统一的道路surfaceilluminance) The average illuminance on the 0. 48. Spot ratio 1:2

5. In accordance with road illumination. ( Practice 1/2 center spot arrived in 25 lux, 1/4 center intensity reached 15 lux, 16 meters minimum 4 lux light intensity, the stacked about 6 lux light intensity.
