Abstract: PROBLEM TO BE SOLVED: To provide a small, low-cost bulb-form fluorescent lamp by simplifying a starting-circuit and a gate drive circuit as a precondition for sharing the gate drive circuit to a pair of FETs. SOLUTION: In this bulb-form fluorescent lamp, an N-channel type FETSN and a P-channel type FETSP are serially connected between dc power sources 4, a gate drive circuit GC common to the FETSN and FETSP is disposed, and a starting-circuit ST is constructed so as to turn the N-channel type FETSN on first when activated. By starting the N-channel type FETSN first when activated, the starting-circuit ST can be simplified. Furthermore, by using a series resonant circuit SR serially resonating to the feedback voltage of a feedback winding (s) for the gate drive circuit GC, a gate drive voltage can be attained by serially resonating to boost voltage. Therefore, a feedback means (s) can be reduced in size.
