Abstract: Based on the data of voltage and current measured via digital oscilloscope,the channel model of one-dimensional wall steady arc accounted for the discharge mechanism of fluorescent lamp is studied. The load characteristics of discharge tube is discussed,which depends on the parameters used and harmonic analysis.

Key words: fluorescent lamp, arc discharge, plasma, harmonic analysis, negative resistance, power factor
