Abstract (en)
[origin: WO2015165898A1] The invention relates to a circuit arrangement having at least one LED assembly (15) and a controller (50) for providing a supply current (IBALLAST) for the LEDs (17), wherein the LED assembly (15) is assigned an identification element in the form of a current sink (20) which is connected to the controller (50) via a parallel feedback circuit (25), said controller (50) being designed to provide a suitable supply current for the LEDs (17), based on a current flow (IFEEDBACK) produced via the feedback circuit (25).
