Abstract (en)
[origin: WO2011015468A1] In circuitries of the type used so far, amperage is measured during the ignition of a discharge lamp (LP) and is controlled by varying the frequency of this ignition current. The same type of control is now also used to adjust the preheating current. To this end, the measured amperage values are manipulated during preheating in a predetermined manner, otherwise the same closed control loop is used in an application-specific circuit (100').
