Abstract

Die Erfindung betrifft eine Beleuchtungsanordnung mit einem LED-Modul (1) und einem Netzteil (2) zur elektrischen Versorgung des LED-Moduls, wobei ein von einer optischen Ausgangsgröße des LED-Moduls abhängiges Meßsignal (6) erzeugt wird, das Meßsignal (6) in das Netzteil (2) eingespeist wird, und das Netzteil (2) die elektrische Versorgung des LED-Moduls (1) so anhand des Meßsignals (6) regelt, daß im Betrieb das LED-Modul (1) eine vorgegebene optische Soll-Ausgangsgröße einhält, oder das Netzteil (2) in Abhängigkeit des Meßsignals (6) die elektrische Versorgung des LED-Moduls unterbricht.
