Two inverter circuits each having a transformers are arranged at both ends of a fluorescent bulb for push- pull driving lighting. The feedback windings of the transformers of the respective inverters not used for self-excited oscillation are connected to each other and the transformers whose feedback windings are connected are connected by the same-phase connection or reverse-phase connection. According to the connection method, the connection method of the fluorescent bulb connected to the secondary windings of the transformers is modified, so that when a plurality of fluorescent bulbs are simultaneously driven in a fluorescent bulb operating device, it is possible to uniformly light the entire fluorescent bulb regardless of the length and number of the fluorescent bulbs. ® KIPO & WIPO 2007
