Electronic ballast device with iron core electroinduction

The utility model relates to an electronic ballast of a fluorescent lamp, which belongs to an illumination electric appliance. The utility model is composed of an iron core inductor, a capacitor, a diode, a resistor, a lamp socket, etc. The iron core inductor replaces a value limiting resistor for limiting the peak current of the fluorescent lamp in the existing electronic ballast. The utility model solves the problems that a current limiting resistor can not be installed in the lamp socket or in a ballast casing because the power consumption of the resistor which is used for limiting peak current is high in a capacitance voltage doubling electronic ballast. The utility model is characterized in that the low frequency iron core inductor and a current doubling rectifier are connected in series, and the utility model which is used for the fluorescent lamp has the advantages of good reliability, low cost, etc.
