Title: Discharge lamp lighting device
Inventor: KUBOTA HIROSHI
IPC: H05B41/24
Filed: 1998-12-22
Abstract: PROBLEM TO BE SOLVED: To provide a discharge lamp lighting device capable of protecting a discharge lamp when it is not suitable. SOLUTION: When power is turned on, a base drive circuit 5 starts to operate through a starting resistor R1 and makes a transistor Q1 perform a high-frequency switching operation. This resonates a parallel resonant circuit 3 and a voltage is induced in filament preheating windings Tr1d, Tr1e of an inverter transformer Tr1 so that filaments FL1, FL2 of a fluorescent lamp FL are preheated. A resonant voltage is induced in a secondary winding Tr1b so that the fluorescent lamp FL is lit with high-frequency waves. When the fluorescent lamp FL comes into a short-circuit state due to the termination period of its service life, a voltage is not induced in a power winding Tr1c close-coupled to the secondary winding Tr1b, so that no power source remains for the base drive circuit 5 and accordingly, the transistor Q1 cannot be driven.  The inverter circuit 2 is prevented from successively operating and applying stress on the transistor Q1 and the like.
