Abstract (en)

The arrangement has an inverter with a bridge circuit having switches (S1, S2) that are arranged in series. A lamps-supply unit (10) supplies an electrical lamp (LP) with energy from the circuit that has an inductor (L1). The circuit has a center point (M) that is coupled with a connection for the lamp by the inductor. The unit has a light emitting diode (LED)-supply unit (12), which is designed to supply an LED with energy. An independent claim is also included for a method of operating an electrical lamp and a light emitting diode (LED) at a circuit arrangement.
