The invention relates to a circuit arrangement for supplying at least one light-emitting diode (11) which is serially connected to at least one other diode (12) by means of an intermediate central tap (M). The invention is characterised in that the above serial connection (1) is connected to a bipolar constant voltage source (V+/V-, U=, 4) and is provided with at least one bipolar alternating voltage source (V &tilde& , 3, 32) which respectively supplies the central tap (M) via a serial oscillating circuit (2). |
