Abstract

Eine Schaltungsanordnung zur Steuerung mindestens einer Lichtquelle umfasst einen Photodetektor (2), ein Abtastmittel (6) zum wahlweisen Abtasten eines von dem Photodetektor (2) in Abhängigkeit einer ersten und einer zweiten Lichtquelle (10, 12) erzeugten Photodetektorsignals (Iin2) und eine Steuerungseinheit (5), die eingangsseitig mit dem Abtastmittel (6) gekoppelt ist. Weiter umfasst die Schaltungsanordnung eine erste Versorgungsquelle (7), die mit der Steuerungseinheit (5) gekoppelt ist und zur Steuerung mindestens eines Parameters einer ankoppelbaren ersten Lichtquelle (12) ausgelegt ist, und mindestens eine zweite Versorgungsquelle (11), die mit der Steuerungseinheit (5) gekoppelt ist und zur Steuerung mindestens eines Parameters einer ankoppelbaren zweiten Lichtquelle (12) ausgelegt ist. Die Schaltungsanordnung eignet sich beispielsweise für eine RGB-Beleuchtung.
