Solar street lights are how to achieve light control？

The way to achieve light control of solar street lights mainly depends on its internal controller, including the following key steps:

Setting of light control voltage:

A specific light-controlled voltage is set inside the controller, which is the standard for judging the current light intensity. When the sun is weak, the voltage of the panel will drop, and when it drops below this light-controlled voltage (usually 3V), the controller will receive a signal of dark.

Automatic regulation circuit:

After dark, the controller automatically adjusts to disconnect the battery from the light source (such as LED lights), while maintaining the connection with the solar panel, so that it can continue to charge at night or on cloudy days.

On the contrary, during the day, when the light intensity increases and the voltage of the panel exceeds the photocontrol voltage, the controller will delay for a period of time (this time can be set) to ensure a smooth transition of voltage, and then disconnect the solar panel from the battery, and connect the light source, and start lighting.

This light control mechanism ensures that the solar street light can be automatically adjusted at any time according to the ambient light, thus effectively saving energy and improving efficiency.
