Abstract

In mindestens einer Ausführungsform ist das Verfahren zum Betreiben einer Anordnung (1) eingerichtet. Die Anordnung (1) weist N strahlungsemittierende Halbleiterchips (2) auf. Die Halbleiterchips (2) sind in einer elektrischen Serienschaltung angeordnet. Die Anordnung (1) umfasst mehrere Schaltelemente (3), wobei jedem der Halbleiterchips (2) eines der Schaltelemente (3) elektrisch parallel geschaltet ist. Es beinhaltet die Anordnung (1) einer Ansteuereinheit (4) zum voneinander unabhängigen Ansteuern der Schaltelemente (3). Die Anordnung (1) umfasst eine Konstantstromquelle (5) zum Bestromen der Serienschaltung. Bei einem Ausschalten wird der jeweilige, einem Schaltelement (3) zugehörige Halbleiterchip (2) von dem Schaltelement (3) elektrisch überbrückt. Ein Schutzmodul (6) der Anordnung (1) ist dazu eingerichtet, bei einem Ausschalten von einem oder mehreren der Halbleiterchips (2) Stromspitzen zu reduzieren oder zu verhindern.
