The four main parts of a lighting control system are:
Control devices, such as switches, dimmers and sensors, which allow users to manually or automatically turn lights on and off and adjust their brightness.
Control panels, which act as the brain of the lighting control system and provide power, communication and control functions.
Wiring, which connects the control devices and control panels to the lights and other components of the system.
Software, which provides a user interface for programming, monitoring and controlling the lighting system.
Some advanced lighting control systems may also include additional components such as gateways for connecting to a building management system (BMS) or the internet, as well as power supplies and other accessories.
