Solar street lamps use sunlight as energy, batteries store energy, and LED lamps as light sources. They are charged during the day and used at night without complicated and expensive pipeline laying. The layout of lamps can be adjusted at will, which is safe, energy-saving and pollution-free, stable and reliable without manual operation, energy-saving and maintenance-free.
The system consists of solar cell module (including bracket), LED lamp holder, controller, storage battery and lamp post. The lamp base part uses 1W white LED matrix as light source. In the solar power supply system, the performance of the battery directly affects the comprehensive cost and service life of the system. The battery used by our company is a special colloidal battery for solar energy, and its service life is more than 3 times that of the ordinary lead-acid maintenance-free battery, which can reach 5-8 years! Conducive to the reduction of system maintenance costs; the charge and discharge controller has light control, time control, overcharge protection, overdischarge protection and reverse connection protection, etc., achieving a high cost performance.
The working principle of the system is simple. The solar panel made of photovoltaic effect principle receives solar radiation energy during the day and converts it into electric energy, which is stored in the storage battery through the charge-discharge controller. When the illumination gradually decreases at night and the open-circuit voltage of the solar panel is about 4.5V, the charge-discharge controller acts and the storage battery discharges the lamp holder. After the light comes on for 8.5 hours, the charge and discharge controller acts and turns off the lights.The main function of the charge and discharge controller is to protect the battery and control the time of turning on and turning off the lights.
LED solar street lamp uses solar energy as power supply to provide road lighting at night, and it adopts high luminous efficiency LED light source design, which has the advantages of high brightness, green environmental protection, simple installation, stable and reliable operation, no cable laying, no conventional energy consumption, long service life, etc. Especially, this product controller adopts multiple energy-saving circuit design, and has overcharge, overdischarge, reverse connection and automatic light control device, which comprehensively improves LED luminous efficiency and greatly saves electric energy. This product uses the solar energy of solar panel to convert into electric energy to charge the storage battery during the day, and discharges the storage battery at night to make the LED lamp shine, which belongs to the green energy product which is strongly advocated and utilized by today’s society. Mainly used in urban roads, residential roads, industrial parks, landscape lighting, tourist scenic spots, parks, courtyard green belts, squares, pedestrian streets, fitness and leisure squares and other places.
