Abstract

Die vorliegende Erfindung bezieht sich auf ein elektronisches Vorschaltgerät zum Betrieb einer angeschlossenen Lampe (LL), welches dazu ausgelegt ist, den Lampenstrom zu modulieren. Dabei wird der Lampenstrom so moduliert, dass dessen zeitlicher Verlauf zumindest einen Teil der Daten des Vorschaltgeräts, der angeschlossenen Lampe (LL) und des Betriebes darstellt. Die Modulation des Lampenstromes wirkt sich in einer Modulation des Lichtstromes aus, so dass über die Lichtstrommodulation Informationen übertragen werden können.

The present invention relates to an electronic ballast for operating a connected lamp (LL) which is adapted to modulate the lamp current. In this case, the lamp current is modulated so that its time course is at least part of the data of the ballast, the connected lamp (LL) and the operation. The modulation of the lamp current affects in a modulation of the luminous flux, so that information can be transmitted via the Lichtstromodulation.
