BALLAST FOR DISCHARGE LAMPS

摘要

PURPOSE: An electronic ballast for a discharge lamp is provided to provide the sine wave voltage of the high frequency to the discharge lamp, thereby reducing the emission of the electromagnetic wave. CONSTITUTION: An inverter provides an out. An IL converting unit senses the current value IL which is proportional to the current amount. A VL converting unit(120) senses the voltage value VL which is proportional to the voltage. A lighting sensing unit(130) senses the lighting status of a discharge lamp. A control unit(200) forms the output of the inverter into an enable/disable status.
