Abstract
PURPOSE:To seek to leng then the life of a lamp by providing the first inverter circuit connected to the power source and the second inverter circuit which connected one electrode of a discharge lamp to the primary side of an insulating transformer as a preheating circuit for the discharge lamp and the other electrode to the primary side. CONSTITUTION:A transistor 5 is turned on after a certain time from the turn-on of power source 1 and a discharge lamp 2 is lit by the output of the first inverter circuit 12. And when a transistor 52 in the second inverter circuit 54 is ON, current is supplied from the power source 1 to the primary side of an insulating transformer 53 and one electrode of the lamp 2, and voltage is generated on the secondary side of the transformer 53 and preheating current is supplied to the other electrode of the lamps 2. When the transistor is OFF, preheating current is supplied to one electrode of the lamp 2 by the energy saved in the primary side of the transformer 53 when it was ON and the other electrode is preheated by the voltage generated on the secondary side of the transformer 53. Hereby life extension becomes possible.
