Patent ID: 7144288

Claim:
A process for producing a flat radiator discharge lamp which is designed for dielectric barrier discharges and which includes: a discharge vessel, which comprises a cover plate and a base plate which are separate at the start of the process and a frame, for holding a discharge medium in a discharge chamber of the discharge vessel, a set of electrodes ( 5 ) for producing dielectric barrier discharges in the discharge medium, and a dielectric layer between at least part of a set of electrodes ( 5 ) and the discharge medium, in which process, during a filling step which precedes closing of the discharge chamber, the cover plate of the discharge vessel is held in a raised position by a support element ( 1 ′– 1 ″″, 2 ′– 2 ″″, 15 ) that is arranged outside of the frame, which support element ( 1 ′– 1 ″″, 2 ′– 2 ″″, 15 ) is at least partially softened ( 15 , 16 ) by the application of heat, in order for the discharge chamber to be closed, with the result that the part ( 3 ) of the discharge vessel which has been held in a raised position is lowered, characterized in that the support element ( 1 ′– 1 ″″, 2 ′– 2 ″″, 15 ), while the discharge vessel part ( 3 ) is being held in a raised position, is arranged entirely outside the discharge chamber.
