Abstract
A circuit assembly for operating a discharge lamp is disclosed having DC input terminals, a bridge circuit to implement a first bridge midpoint, an output coupling the discharge lamp thereto and a shunt resistor with a tapping point and a device for detecting overload operation. A device for ignition control of the discharge lamp, having an input for supplying a measurement signal and a switch control device is provided connected to the device for detecting overload operation and the ignition control device. The switch control device is designed to modify control signals for at least a first and second electronic switch as a function of the output signals of the device for detecting overload operation.
