Intelligent Control Strategy for Ceramic Metal Halide Lamps

Yuzhuo Pan, Shanhe Su


An intelligent control strategy for driving a 35w Ceramic Metal Halide (CMH) lamp is built. By integrating the microcontroller STM32F103 with the digital potentiometer X9313 in the circuit, we are able turn the lamp on and off flexibly. The lamp power can be altered automatically according to the environment, since it is designed to be linearly dependent on the resistance of X9313. The energy conversion efficiency of the driving circuit can be larger than 88%. A remote desktop client on the Android is developed for the purpose of wireless and convenient control. The proposed model will useful for designing high performance small-wattage CMH lamps.
