Abstract:
Discharge lamp (1)having a discharge vessel (2) which is at least partially transparent and filled with a gas filling,a number of electrodes (3-5) which are arranged on or in walls of the discharge vessel (2),and at least one dielectric barrier (6-8) made from one or more layers withthe thicknesses d.sub.Bi and withthe dielectric constants .di-elect cons..sub.Bi between at least one electrode (3-5) and the gas filling, suitable for a dielectrically impeded discharge in the discharge vessel (2) between electrodes of different polarity, characterized byan electrically conducting screen (12, 13) which surrounds the discharge vessel (2) at least partially,the discharge vessel (2) made from one or more layers withthe thicknesses d.sub.Di and withthe dielectric constants .di-elect cons..sub.Di,which electrically separates the screen (12, 13) from at least one electrode (3-5),and wherein ##EQU4##
