What's the difference between a solar street lamp and a street light complementary street lamp?
The working principle of the system is simple, the use of solar photovoltaic panels during the day the principle of solar radiation and into electrical energy output, through the charging and discharging controller is stored in the accumulator. When night illumination gradually reduced to about 10lux, Jin Zhan solar energy battery open circuit voltage of about 4.5V, the charge and discharge controller to detect the a voltage value of the battery discharge lamp action. After 8.5 hours battery discharge, the charging and discharging controller moves and the battery discharge is finished. The main function of the charge and discharge controller is to protect the battery.
The system comprises a solar battery component part (including bracket), LED lamp, control box (with controller and battery) and lamp parts; Jin Zhan solar panels light efficiency reached 127Wp/m2, higher efficiency, is favorable for the wind resistant design of the system; the cap portion with 1W white LED and 1W yellow light LED integrated in printing the circuit board is arranged in a certain distance matrix as plane light source.The control box body is made of stainless steel, and the utility model is beautiful and durable, and the maintenance free lead-acid battery and the charging and discharging controller are arranged in the control box. This system chooses the VRLA battery, because of its little maintenance, so it is also called "maintenance free battery", the system is conducive to the maintenance cost is reduced; the charge and discharge controller both functions in the design (with light control, time control, overcharge protection, over discharge protection and reverse protection etc.) and cost control, to achieve a very high price.
Solar street lamp uses solar energy during the day, charging at night, without complicated and expensive pipeline laying, adjustable lighting layout, safety and energy saving and no pollution, without manual operation is stable and reliable, saving electricity and maintenance free.
