A circuit arrangement for operating a chain comprising at least one light emitting diode on an AC voltage, in particular mains voltage, comprising a rectifier with an input circuit for drawing the AC voltage and an output circuit, into which a rectified AC voltage is output. An energy store is provided in the output circuit, in particular a storage capacitor, to which the LED chain can be connected in a parallel circuit. A current controller interrupts, during operation, the charging of the storage capacitor each time the current in the output circuit has risen to a specific threshold current, and enables charging again when the voltage in the output circuit has then fallen to a specific threshold voltage. |
