Introduction: with the development of The Times, nowadays, solar street lamps have been a kind of traffic condition lamps that use solar energy as the external power supply energy for street lamps. It can be used in our urban life.

The working principle of solar street lamps is to convert solar energy into electric energy to realize illumination. The top of the street lamp is solar panel, also known as photovoltaic module. During the day, the photovoltaic modules made of polysilicon convert solar energy into electric energy and store it in the battery, so that the solar street lamp is intelligently controlled. Under the control of the device, the solar panel is irradiated by sunlight, absorbs solar light and is converted into electric energy, and the solar cell module charges the battery pack during the day. In the evening, power is supplied to the light source through the control of the controller to illuminate people at night. At night, the battery pack provides power to supply power to the LED light source to achieve lighting functions.
Solar streetlights use solar energy to generate electricity, so there are no cables and no leakage or other accidents. The DC controller ensures that the battery pack is not damaged by overcharging or overdischarging, and has functions such as light control, time control, temperature compensation, lightning protection, and reverse polarity protection. No need to lay cables, no AC power supply, no electricity bills.
The low-carbon, environmentally-friendly, safe and reliable advantages of solar street lamps have been recognized by customers and have been greatly promoted. Therefore, it can be widely used in urban main and secondary roads, communities, factories, tourist attractions, parking lots and other places.
