Introduction of solar lights

Street lamps are a very common lighting product in cities. Street lamps are installed on both sides of the road. Generally, one to two lamps are installed every ten meters.

In the past, street lamps were all illuminated by electricity. The cost of electricity generated by this lighting method is relatively large.

Therefore, in order to save energy consumption of street lamps, many cities have begun to use solar street lamps. Solar street lamps can absorb solar energy during the day and use it at night. Solar power is very environmentally friendly.

Today we will introduce the working principle of solar street lights.

Solar street lights use solar panelsto convert solar radiation into electrical energy during the day, and then store the electrical energy in batteries through an intelligent controller.

When night comes, the intensity of the sun gradually decreases. When the intelligent controller detects thatthe illuminance decreases to a certain value, it controls the battery to provide power to the light source load, so the light source will automatically turn on when it is dark.

The intelligent controller protects the charging and over-discharging of the battery, and controls the turn-on and lighting time of the light source.

About solar battery

The battery is equivalent to the heart of the solar street light. It supplies the function of the solar street light. If there is a problem, the solar street light will not work.

Commonly used solar street lights now generally use lithium batteries, which are mainly environmentally friendly, portable, and easy to install. Traditional batteries have almost been eliminated. When the battery is full, the controller will also disconnect the closed circuit formed by the battery board and the battery, so that it will no longer be charged.

The controller is equivalent to the brain of the solar street light and supports the operation of the solar street light.
