Abstract

An intelligent LED lamp group control device using an existing wall switch for controlling a group of LED lamps includes an AC power converter, an interface for intelligent control using an interface circuit for upgrading the existing wall switch for scene group control. The device further includes a night lamp control input port, an emergency operation switch, an external set control box connector, a wall switch input unit, a control configuration set interface, a power failure battery input port and a night lamp and RS-485 serial port. The device enables one single controller to achieve control of and provide power supply to multiple LED lamps, and uses a communication control interface for converting the power supply originally provided to the LED lamps into a logic control signal so that the wiring layout and location of the original lighting control wall switch can be used.
