What is the structure and principle of solar street lights?

Kwong Sang photovoltaic effect principle of the solar cell of the solar lights, solar energy during the day absorbing solar photons of energy generated by the controller to charge the battery pack, when night falls low level of lighting fixtures or around the battery to provide power to the DC Light load. The DC controller can ensure that the battery is not damaged by overcharging or over-discharging under any circumstances, including sunny or long-term rainy weather. It also has light control, voice control, temperature compensation, and lightning protection and reverse polarity. Sexual protection and other functions.

Solar street lights consist of the following components: solar cells, batteries, control inverters, light control and timers, and illuminators. The solar street light is an automatically controlled working system that automatically controls the work as long as the operating mode of the system is set. The control mode is generally divided into three types: light control start, light control off; timing control start and timing control off; light control start, timing control off, we generally select the mode of operation, when the light is low to the set value The sensing control activates the lamp and simultaneously starts timing. When the time is up to the set time, it stops working.

The solar cell of this system has two functions:

1. Charging the battery during the day;

Second, do light control sensor, charge and discharge with RC components. We generally use 18 watt or 36 watt low pressure sodium lamps as the light source because its light efficiency is the highest among the light sources.

Solar street lights are ideal road lighting. With the improvement of people's life and the continuous development of society, it will be widely used, so that the sun gives the light of the earth to illuminate humans at night.
