摘要：
An arrangement for supplying a constant current to at least one LED includes a current source (2; 2a, 2b) with an output capacitor (3) connected across the terminals of the current source. An output inductor (4) is associated with the output capacitor (3) whereby the current supplied flows through the inductor (4). A smoothing resistor (5) is preferably connected in parallel to the output inductor (4).
