Abstract
A light source device for a dielectric barrier discharge lamp including a dielectric barrier discharge lamp having a discharge space, the discharge space being filled with a discharge gas which produces excimers by a dielectric barrier discharge; first and second electrodes, a dielectric positioned between at least one of the first and second electrodes for inducing a discharge in the discharge gas, and a feed device for applying an essentially periodic AC high voltage to the first and second electrodes of the dielectric barrier discharge lamp. The feed device includes a setting mechanism for adjusting both the control frequency of the essentially periodic AC high voltage and the amplitude of the essentially periodic AC high voltage in accordance with a set control frequency.
