Schaltungsanordnung zum Betrieb einer Entladungslampe

摘要

The 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 a 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.
