Abstract

The radiative and thermodynamic parameters of a dielectric barrier discharge XeBr and KrBr excilamp were studied. The power expended in heating the gas mixture and the excilamp bulb was determined by measuring the fast and slow components of a pressure jump. The power consumed by the exilamp was estimated using oscillograms of voltage and current pulses. The maximum UV power and efficiency of a XeBr excilamp were 3.8 W and 7.5%, respectively. For the same conditions the maximum UV power and efficiency of a KrBr excilamp were 1.6 W and 3%, respectively. Analysis of the experimental results shows that at low mixture pressures most of the discharge power is expended in heating the gas and at the elevated pressure the most of the discharge power goes into the generation of acoustic waves and heating of the excilamp bulb walls through electron and ion bombardment. The concept proposed earlier for the energy balance in DBD lamps as thermodynamic systems was verified.
