Abstract

Elektronisches Vorschaltgerät zum Betrieb wenigstens einer Lampe, vorzugsweise einer Gasentladungslampe, mit einem zwischen einem ersten (T1) und einem zweiten Schalter (T2) angeordneten Mittenabgriff (M), der mit einem Anschluss für die Lampe verbindbar ist sowie mit einem einen Messeingang (LSCS) zur Totzeiterkennung aufweisenden IC (1), der zum Betrieb des Vorschaltgeräts vorgesehen ist, wobei der Messeingang (LSCS,ME) vorzugsweise zwischen einem mit dem Bezugspotential verbundenen Shunt (R1) und einem Schalter (S2) eingekoppelt ist, und mit einer Schaltung zur Variation des am am Messeingang (LSCS, ME) anliegenden Signals, wobei die Schaltung dergestalt als Übertragungsschaltung (ATZ) zum Erreichen vorgegebener Signalpegel am Messeingang (LSCS,ME) ausgebildet ist, dass ein Signal zum Schalten eines Schalters (T2) während einer an dem Mittenabgriff (M) anliegenden und vernachlässigbaren oder dort nicht vorhandenen Spannung (Nulldurchgang des Signals) erzeugt wird.
