How does the solar street light controller control night lighting?

With the development of solar technology, solar street lights have become the first choice for street lighting. Careful friends should note that the turn-on time of street lights is basically the same every night, and there is a difference between winter and summer.

In the general century, the usual practice of solar street light manufacturers in sunny rural areas is timing control, and the on-time and off time can be set. Some control systems will incorporate an automatic mode, which is achieved by a photoresistor or by detecting the output voltage of the solar panel.

1. Timing mode

The solar street lighting system consists of key modules such as solar panels, batteries and controllers. Among them, the controller plays relevant roles such as voltage detection, battery charge, and discharge management, and street lights on and off. The turn-on time and turn-off time of the street lights can be set. Opening hours are late summer and early winter. The opening time and closing time can be set. This is a general control mode, and managers only need to modify the time in the control room according to regulations.

2. Auto Mode

Some solar street lights have an automatic mode, which can be achieved by a photoresistor or by detecting the panel voltage. The photoresistor is a special kind of resistor whose resistance is closely related to light intensity. The stronger the light, the smaller the resistance, and the weaker the light, the greater the resistance. Photoresistor. Comparator. Triode and other components can realize light control circuit. It can turn off the light when the light is strong and turn on the light when the light is weak. In addition, the output power of the solar panel is high when the light intensity is strong, and the output power is low when the light intensity is weak, which can realize automatic lighting control.
