Abstract

The invention relates to a new design of discharge vessel for a discharge lamp, in which dielectrically impeded discharges are to be generated. In this case, a discharge vessel plate 1, 9 is, as it were, of two-fold design, specifically as a first discharge vessel plate 1 with an external electrode set and, in addition, as a stabilizing plate 9 outside the first discharge vessel plate 1.

Claims

1-15. -15. (canceled)

16. A method for producing a discharge lamp comprising:

(a) providing a discharge vessel having first and second discharge vessel plates (1, 2) between which a discharge space is arranged, a stabilizing plate, and an electrode set being arranged on a side, averted from the discharge space, of the first discharge vessel plate, the first discharge vessel plate (1) forming a dielectric barrier between the electrode set and the discharge space, the discharge vessel plates and the first discharge vessel plate and the stabilizing plate being held apart by spacers,

(b) filling the discharge space with a discharge medium, and

(c) heating the discharge vessel to soften the spacers so that the two discharge vessel plates (1, 2) are interconnected, and the first discharge vessel plate (1) and the stabilizing plate (9) are interconnected.

17. The method of claim 16 wherein the second discharge vessel plate has inwardly pointing supporting projections bearing a solder glass material and the first discharge plate has solder glass points facing the stabilizing plate, during the heating of the discharge vessel, the solder glass material fuses with the first discharge vessel plate and the solder glass points fuses with the stabilizing plate.
