Abstract

It is proposed for limiting the DC peak current value and/or the AC inrush current after the ignition of a discharge lamp (HL, NL) connected to an AC supply source (U) to connect a further current-limiting circuit part (B) in series with the conventional inductor (D) serving for limiting the current. At the instant when the discharge lamp is ignited this circuit part is in a first state in which it limits to a larger extent the current flowing through and switches over to a second state after a specific time has expired, in which state it limits to a lesser extent the current flowing through. The switching-over process can be carried out by a temperature-sensitive switch (S), which is in thermal contact with a component which is heated up by the current flowing through, or by a control circuit (ST). <IMAGE>
