Solar street lamp is powered by sunlight. The system is composed of solar cell module, LED lamp head, control box and lamp pole. The control box body is made of stainless steel, beautiful and durable; Maintenance-free lead-acid battery and charge and discharge controller are placed in the control box, which is conducive to reducing the maintenance cost of the system. Charge and discharge controller in the design of full function (with light control, time control, overcharge protection, overdischarge protection and reverse connection protection) and cost control, to achieve a high cost performance.

Working principle of the system is simple, the use of light born V effect principle of solar cells, 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 illumination was gradually reduced to about 10 lux, solar panels around the open circuit voltage of 4.5 V, charge and discharge controller detects the voltage value of the action, The battery discharges the lamp cap. After the battery is discharged for 8.5 hours, the charge and discharge controller acts and the battery is discharged. The main function of charge and discharge controller is to protect the battery.

In the solar street lamp system, the wind resistance design is a very important problem in the structure. The wind resistance design is mainly divided into two parts, one is the wind resistance design of the battery component bracket, and the other is the wind resistance design of the lamp pole. The wind resistance design of the solar cell module support, according to the technical parameters of the battery module manufacturer, the solar cell module can withstand the upwind pressure of 2700Pa. If the wind resistance factor is set to 27m/s(equivalent to a category 10 typhoon), the wind pressure of the battery module is only 365Pa according to non-viscous hydrodynamics. Therefore, the components themselves can withstand wind speeds of 27m/s without damage. Therefore, the key to consider in the design is the connection between the battery assembly bracket and the light pole. The wind resistance design of the street lamp pole, the weld width selected by the design meets the requirements, as long as the welding quality can be guaranteed, the wind resistance of the lamp pole is no problem.

The main function of solar charge and discharge controller is to protect the battery. Basic functions must have overcharge protection, overdischarge protection, light control, time control and anti-reverse connection.

Solar street lamp is safe, energy saving and pollution-free, stable and reliable without manual operation, electricity saving and maintenance free.

Solar lights include solar street lights, solar garden lights, and solar lawn lights. They work in the same way, but their size and brightness are different.
