In the case of an electronic ballast () for operating a lamp () or an operating device for illumination means, having mains terminals () for connecting the ballast () or operating device to a current supply, output terminals () for connecting a lamp or light source to the ballast () or operating device and a control unit () for controlling and/or regulating an operating voltage delivered to the lamp (LA) or light source via the output terminals (), external control information (Vprog) for programming or configuring the operating behavior of the operating device is delivered to the control unit () via a programming input, and stored in a memory () associated with the control unit (). In accordance with the invention, the programming input is formed by means of the mains terminals () and/or the output terminals () of the ballast () or of the operating device (), which are connected internally with the control unit ().

Electronic ballast or operating device for illumination means having programmable or configurable control unit

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.
