A circuit for the generation of ignition pulses for a lamp has: an
ignition pulse transformer, a device for the generation of ignition
pulses (ignition pulse generator) at a primary winding of the ignition
pulse transformer, which are transformed in the secondary winding of the
ignition pulse transformer, a voltage detector for the detection of the
voltage value of the transformed ignition pulses, and a voltage regulator
for regulating the voltage value of the transformed ignition pulses to a
predetermined reference value. The ignition pulse generator has, in a
series circuit, a pulse capacitor and a switch, parallel to the secondary
winding of the ignition pulse transformer and the lamp, wherein the
regulator for the voltage value of the transformed ignition pulses sets
at the pulse capacitor the voltage applied at an ignition time point. The
voltage at the pulse capacitor can be set by means of selection of the
switch-on and/or switch-off time points of the switch.
