Abstract

Die vorliegende Erfindung betrifft eine Vorrichtung mit mehreren elektrisch in Serie geschalteten Leuchtmitteln, mindestens einem Überbrückungsstrompfad, durch den mindestens eines der Leuchtmittel elektrisch überbrückbar ist, einer Stromquelle zur Stromversorgung der Leuchtmittel sowie einer Strombeschränkungseinrichtung, welche im Falle einer elektrischen Überbrückung mindestens eines der Leuchtmittel einen durch die nicht überbrückten Leuchtmittel fließenden Strom beschränkt.
