Abstract
A circuit arrangement for controlling at least one light source comprises a photodetector (), a sampling circuit () for selectively sampling a photodetector signal (lin) generated by the photodetector () as a function of a first and a second light source (), and a control unit (), which is coupled on the input side to the sampling circuit (). The circuit arrangement further comprises a first power-supply source (), which is coupled to the control unit () and is designed for controlling at least one parameter of a first light source (), and at least one second power-supply source (), which is coupled to the control unit () and is designed for controlling at least one parameter of a second light source (). The circuit arrangement is suitable, for example, for RGB lighting.
