Solar street lamps retrofitting standards1

Solar street lamps retrofitting standards. Solar street lamps standard generally is: 1. Light conversion rate 17%, Each square solar power is 1000 w, the actual efficiency of 170 w) 2. Current market street lamp lens materials for the improvement of optical materials, through the rate of 93% or higher heat resistance - 3



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. 】 The standard. Solar street lamps standard is commonly:

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

　　2. Current market street lamp lens materials for the improvement of optical materials, through the rate of 93% or higher heat resistance - 38 - + 90 degrees.

　　3. Solar street lamp lens, lens is mainly used for solar street lamps, light as the rectangle, material is PMMA optical material, through the rate of 93% or higher heat resistance - 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. （ Actual 1/2 center spot of 25 lux, 1/4 center intensity 15 lux, 16 meters minimum 4 lux light intensity, the overlapping intensity 6 lux.
