ARRANGEMENTS FOR DISCHARGE LAMPS

摘要

The appts. includes an inverter circuit connected to a DC power source for generating an energy for starting and operating the lamp current-limiting coil disposed between the inverter circuit and lamp for limiting a current flowing through the lamp and a starting capacitor connected in parallel with the discharge lamp. The starting capacitor forms a first resonance circuit which is a serial resonance circuit in association with currentlimiting coil when the discharge lamp is switched on. The inverter circuit comprises a second resonance circuit including an oscillation coil and a capacitor.
