Low Frequency Square Wave Electronic Ballast for Metal Halide Lamp
Abstract：Electrical characteristics and generation mechanism and solutions of acoustic resonance of metal halide lamp are described briefly.Instead of the traditional analog control mode,a digital control mode is used to control the four running stages of metal halide lamp step by step to avoid causing the acoustic resonance phenomenon.In this way,the low frequency square wave electronic ballasts for metal halide lamp which have higher performance parameters are developed successfully.
