MICROCONTROLLER-BASED MULTIFUNCTIONAL ELECTRONIC SWITCH AND LIGHTING APPARATUS HAVING THE SAME

摘要

A microcontroller based multifunctional electronic switch uses a detection circuit design to convert external control signal into a message carrying sensing signal interpretable and executable to a microcontroller. Based on a signal format of said message carrying sensing signal received said microcontroller operates to perform at least an on/off switch control mode, a dimming control mode and an illumination level switching control mode. When said signal format of said message carrying sensing signal detected is a short voltage signal, said microcontroller operates to perform said on/off control mode. When said signal format of said message carrying sensing signal detected is a long voltage said microcontroller operates to perform said dimming control mode. When said signal format of said message carrying sensing signal detected is a constant voltage signal, said microcontroller operates to perform said illumination level switching control mode.
