Patent attributes
A microcontroller-based multifunctional electronic switch for lighting control uses a detection device to sense and convert at least one external control signal into at least one message carrying sensing signal interpretable to a microcontroller. Based on a signal format of the message carrying sensing signal received, the microcontroller recognizes working mode chosen by the external control signal and thereby executes an appropriate lighting control process. The system and method of the present invention may be equally applicable to detection design, such as touch less and direct touch interface implemented by infrared ray sensor, push button or wireless control device in conjunction with APP preloaded, for performing multiple working modes including on/off mode, dimming mode, color temperature tuning mode, color temperature switching mode, color temperature dim to warm mode, commanding mode for controlling a lighting family comprising a plurality of member lamps remotely located or delay shut off mode.
