With the development of solar energy technology, solar garden light with panel has become the first choice for street lighting. Careful friends should notice that the turn-on time of street lights is basically the same every night, and there is a difference between winter and summer. So how do the street lights switch at night?
solar garden light with panel
In the average century, solar garden light with panel manufacturers in sunny rural areas usually use timing control, and can set the on time and off time. Some control systems will add an automatic mode, which is achieved through a photoresistor or detecting the output voltage of the solar panel.
One, timing mode
Solar garden light with panel lighting system consists of key modules such as solar panels, batteries and controllers. Among them, the controller plays a related role in voltage detection, battery charge and discharge management, and street lamp opening and closing. The turn-on time and turn-off time of the street light can be set. Opening hours are late summer and early winter. You can set the opening time and closing time. This is a general control mode, and managers only need to modify the time of the control room as required.
Second, automatic mode
Some solar garden light with panel has an automatic mode, which can be realized by photoresistor or by detecting the panel voltage. Photoresistor is a special kind of resistance, and its resistance is closely related to light intensity. The stronger the light, the smaller the resistance, and the weaker the light, the greater the resistance. Components such as photoresistors, comparators, and triodes can realize light control circuits. 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 higher when the light intensity is strong, and the output power is lower when the light intensity is weak, which can realize automatic lighting control.
The timing control mode is the mainstream control mode, which can precisely control the turning on and off of street lights, and can be flexibly set according to weather conditions; the automatic mode greatly reduces the intervention of the staff. Century Sunshine reminds everyone that the automatic mode cannot be flexibly controlled according to the actual situation. The street lights may be turned on too early or too late.
