The Design of dimmable electronic ballast based on MCU Song yu-hong1 Zhou jia-nong2 (1．Shunde polytechnic, Foshan Guangdong 528333 2．South China University of Technology 510640) Abstract: The hardware and software of electronic ballast based on MCU control system by using FM2822 and Freescale MCU MC9RS08KA2 is reported. This system is flexible to regulate the controlling lamp bright through IR remote. The MCU resource is full used of pyroelectri IR sensor and light-sensitive detector. This realizes energy-saving with some modes. Its validity is proved by experimental results.
