<p>PCT No. PCT/DE96/00198 Sec. 371 Date Aug. 12, 1997 Sec. 102(e) Date Aug. 12, 1997 PCT Filed Feb. 8, 1996 PCT Pub. No. WO96/25833 PCT Pub. Date Aug. 27, 1996The invention concerns a circuit for operating a discharge lamp with a half-bridge generator (T1, T2) wherein a turn-off transistor (T3) can stop the half-bridge generator The energy source for the base current of the turn-off transistor (T3) is formed by starter capacitor (C3) which starts the half-bridge generator (T1, T2), In addition, the collector-emitter section of the turn-off transistor (T3) is directly between the base of the lower transistor (T2) of the half-bridge generator and earth.</p> |
