Abstract

Die Erfindung betrifft eine Beleuchtungseinrichtung 10 mit einer Mehrzahl von in Serien- und Parallelschaltung verbundenen Leuchtdioden 10.1, 10.2, 10.3, 10.4, 10.5, 10.6. Die Beleuchtungseinrichtung 10 umfasst eine Bypassschaltung Z1, Z2, Z3, die bei Ausfall einer Leuchtdiode 10.1, 10.2, 10.3, 10.4, 10.5, 10.6 oder einer Kombination von Leuchtdioden einen Stromfluss durch die betriebsfähigen Leuchtdioden 10.1, 10.2, 10.3, 10.4, 10.5, 10.6 der Beleuchtungseinrichtung 10 ermöglicht.
