Detection of acoustic resonance in metal halide lamps
ISIE 2001. 2001 IEEE International Symposium on Industrial Electronics Proceedings (Cat. No.01TH8570)
Investigation of the acoustic resonance in metal halide lamps is essential for engineers designing a high-frequency electronic ballast. This paper proposes a simple method of detecting the acoustic instability by measuring the lamp voltage. The standard deviation in the lamp voltage is used as an index to determine the occurence of acoustic resonance. With this index, the degree of the lamp arc instability can easily be specified. Experiments are carried out on various 70W lamps to inspect the
