Abstract

Elektronisches Vorschaltgerät zum Betrieb wenigstens einer Lampe (La), vorzugsweise einer Gasentladungslampe, mit einem zwischen einem ersten (S1) und einem zweiten Schalter (S2) angeordneten Mittenabgriff (M), an den in Serie eine Drossel (L1) und ein erster Kondensator (C1) gekoppelt sind, vorzugsweise mit einem weiteren an einem Bezugspotential liegenden Kondensator (C2), wobei der erste Kondensator (C1) vorzugsweise mit einem Anschluss für die Lampe (La) verbunden ist, sowie mit einem einen Messeingang (CS) aufweisenden IC (1), der zum Betrieb des Vorschaltgeräts vorgesehen ist, wobei der Messeingang (CS) zwischen einem mit dem Bezugspotential verbundenen Shunt (R1) und einem Schalter (S2) eingekoppelt ist, wobei eine Begrenzungsschaltung vorgesehen ist, die das am Shunt (R1) abfallende Signal zum Erreichen vorgegebener Signalpegel am Messeingang (CS) variiert, vorzugsweise in seiner Amplitude begrenzt. Ebenfalls wird ein Beleuchtungsgerät und ein Verfahren zum Betrieb eines elektronischen Vorschaltgeräts und/oder eines ein solches aufweisenden Beleuchtungsgeräts beansprucht.

Figure imgaf001
Electronic ballast for operating at least one lamp (La), preferably a gas discharge lamp, with a center tap (M) arranged between a first (S1) and a second switch (S2), to which in series a choke (L1) and a first capacitor ( C1), preferably with a further capacitor (C2) located at a reference potential, wherein the first capacitor (C1) is preferably connected to a terminal for the lamp (La) and to an IC (1) having a measuring input (CS) ), which is provided for the operation of the ballast, wherein the measuring input (CS) between a connected to the reference potential shunt (R1) and a switch (S2) is coupled, wherein a limiting circuit is provided which the falling of the shunt (R1) signal to reach predetermined signal levels at the measuring input (CS) varies, preferably limited in its amplitude. Likewise, a lighting device and a method for operating an electronic ballast and / or a lighting device having such a lighting device are claimed.
