- how to design the solar street light system How to choose and buy solar energy

The above entry is solar light path signal light pole pole a for instance when the choose and buy, today the solar street light a demands recommend instance to you first is lamps and lanterns of choose and buy material and surface treatment: ( 1) Lamps and lanterns, light body with high pressure die casting aluminum alloy,

the above items is to buy solar street light path signal lamp post requirements of an example. Today, I recommend a buy solar street light for example. Materials and surface treatment: first is the requirement of lamps and lanterns 1) Lamps and lanterns with high pressure die casting aluminum alloy, heat dissipation design. Lamps and lanterns is applicable ambient temperature: 40 ℃ to 55 ℃ +. During normal operation, the outer surface temperature rise not to exceed 30 ℃, junction temperature does not exceed 85 ℃, light structure, corrosion resistance. ( 2) Lamps and lanterns protection grade shall not be less than IP65. Protection performance: adopt silicon rubber sealing ring; Dustproof IP66 waterproof level for; Primary prevention: (getting an electric shock 3) Pervious to light cover by the bending of high-strength tempered glass, high temperature above 200 degrees, high light transmittance, impact resistance; The second is the solar lamp light source for 35 watt leds, single head; High power 1 w/light emitting diode ( Racist or crystal) , individual leds luminous efficiency p 100 lm/W, lamp luminous efficiency 80 lm/W, or higher color temperature 6000 k, indicating greater than 75, light attenuation note: this series of Mr Zhang are all examples of the requirements of purchase solar street light, not all of the parameters in detail, also is not a standard option. Please choose according to actual needs and environmental conditions to buy or entrust my company free design.
