Abstract
The invention relates to a circuit arrangement which is used to operate a low pressure discharge lamp (EL), wherein the discharge lamp receives power. Said circuit arrangement is embodied in such a manner that power-determination components (C, L) of the circuit arrangement are embodied in a temperature-dependent manner such that the power consumption of the lamp is limited when the temperature rises. Capacitors (C) and throttles (L) can be embodied in a temperature-dependent manner in a control circuit (AS) of the circuit arrangement.
