Abstract:
A device for operating a dielectric barrier discharge lamp, comprising a feed device for applying a high voltage to the dielectric barrier discharge lamp,wherein the feed device comprises a set-up transformer adapted to apply a high voltage with a periodic waveform to the barrier discharge lamp, said waveform, at a polarity change after a dielectric barrier discharge, having a steep rising waveform and a subsequent ringing, a first wave form maximum or minimum value, a second wave form maximum or minimum value, and a third wave form maximum or minimum value, and for which a ratio of a first difference between the second wave form maximum or minimum value and the third wave form maximum or minimum value relative to a second difference between the first wave form maximum or minimum value and the second wave form maximum or minimum value is produced that is less than or equal to 30%.
