Simple, in fact, the working principle of solar street light, is to use light born v effect principle of solar panels during the day to receive solar radiation and translated into electricity output, after stored in the storage battery charging and discharging controller, the night when the intensity of illumination is gradually reduced to about 10 lux, solar panels open circuit voltage is 4. Around 5 v, charge and discharge controller to detect the voltage value of the action, the battery to discharge lamp holder. As can directly affect the comprehensive cost of solar street lights and running quality and the service life of the battery solar street lamps, request to adopt the suitable battery anode alloy is formula and the ratio of active material, make a battery is more suitable for the use of energy storage battery circulation charge and discharge characteristics. Solar street lamps use LED light source with high luminous efficiency, small power consumption, long service life, low working temperature; Safety reliability, fast response, small unit volume, green environmental protection; Under the same brightness, power consumption is one over ten of incandescent lamp, fluorescent lamp of a third, but life is 50 times of incandescent lamp, fluorescent lamp 20 times, is the incandescent lamp, fluorescent lamp, gas discharge lamp after the fourth generation of lighting products.
