Embodiment Construction

[0027] figure 1 to 3 are used to illustrate the dielectric barrier layer-discharge lamp manufacturing method of the present invention.

[0028] figure 1 A discharge vessel 1 made of soda-lime glass is shown, which is temporarily still open at a first end 2, but whose second end 3 has been sealed with a flat frit 4.

[0029] 2a, 2b respectively show a schematic longitudinal section of the open end 2 of the discharge vessel 1 and a schematic cross section along the section line A-A. The inner wall of the discharge vessel 1 has been provided with two radially arranged linear silver inner electrodes 5a, 5b which are each covered with a dielectric glass barrier layer 6a, 6b. Furthermore, a disc-shaped sealing element 7 has been arranged concentrically in the open end 2 of the discharge vessel 1 . The outer diameter of the disk-shaped sealing element 7 is slightly smaller than the inner diameter of the discharge vessel minus the thickness of the two inner electrodes 5a, 5b includ...

Abstract

The discharge tube (1) of a dielectric barrier discharge lamp is closed in gas-tight manner, without the use of a connecting means, by means of a plate-shaped closure element (7). To this end, the discharge tube (1) has a constriction (10), which encircles the edge of the plate-shaped closure element (7) in an annular manner.

Description

technical field [0001] The invention relates to a dielectric barrier discharge lamp according to the preamble of claim 1 . [0002] This is a discharge lamp in which either the electrodes of one polarity or all electrodes, ie both polarities, are separated from the discharge by a dielectric layer (so-called one- or two-sided dielectric barrier discharge). Such electrodes are also referred to below simply as "dielectric electrodes". The polarity of the electrodes can also be completely changed during operation, that is, each electrode can be used as an anode or cathode alternately. Of course, preferably all electrodes have a dielectric barrier. Further details can be found in document EP0733266B1, which describes a dielectric barrier-discharge lamp. [0003] The above-mentioned dielectric layer can be formed by the wall of the discharge vessel itself, in which case the electrodes are arranged outside the discharge vessel, ie approximately on the outer wall. On the other han...
