The street lamp controller is a device used to control the switching and brightness of street lamps. Its working principle is mainly achieved through light sensors or timers.
The light sensor can sense the brightness of the surrounding environment and automatically control the switch and brightness of the street lamp according to the light intensity.When the ambient light is dark, the sensor will send a signal to turn on the street lamp and gradually reach the set brightness;When the ambient light is sufficient, the street lights will automatically turn off or reduce the brightness to achieve energy saving.
The timer controls the on-off of the street lamp by setting a fixed time.For example, street lights can be set to turn on and off at specific times of the day to meet people’s travel needs.
In addition, some street lamp controllers also have other functions, such as fault detection and remote control.The fault detection function can monitor the working status of street lamps in real time. Once a fault is detected, an alarm will be issued and relevant personnel will be notified for repair.The remote control function allows administrators to control and manage street lights from a remote location through the network or other communication methods.
In general, the working principle of the street lamp controller is to automatically control the switch and brightness of the street lamp by sensing the ambient light or setting the time, so as to achieve the purpose of energy saving and intelligent management.
