A circuit arrangement for producing a control signal (U<SUB>s</SUB>) for the purpose of dimming at least one lamp, including a device ( 10 ) for modifying the phase gating angle corresponding to a dimming input value ( 8 ), it being possible for the device ( 10 ) for modifying the phase gating angle to be fed, at its input, an input signal (U<SUB>e</SUB>), whose phase gating angle is to be modified, and for an output signal (U 1 ) having a modified phase gating angle to be provided at its output; and an output at which the control signal (U<SUB>s</SUB>) can be provided; it also includes a device ( 14 ) for comparing the output signal (U 1 ) with a predeterminable signal (U<SUB>c</SUB>) for the purpose of producing the control signal (U<SUB>s</SUB>), the amplitude of the predeterminable signal (U<SUB>c</SUB>) depending on the amplitude of the input signal (U<SUB>e</SUB>).
