<p>The invention relates to a flat spotlight (1) with a closed, gas-filled discharge vessel (2) and enclosing band-shaped electrodes separated from the discharge by a dielectric layer. The discharge vessel (2) consists of at least one base plate (5) and one cover plate (6) which are assembled by soldering (8) so as to be gastight, and optionally, also by means of an additional frame (7) placed between the cover and base plate. In addition, the band-shaped internal electrodes (3, 4) verge into passages (10, 11), and these passages verge into external power leads (12, 13) in such a way that the internal electrodes (3, 4), the passages (10, 11) and the external power leads (12, 13) are respectively conceived as functionally different sections of structures (3, 10, 12; 4, 11, 13) of the printed conductor type on the cathodes and/or anodes. At least the anodes (4) are respectively coated with a dielectric layer (17). The passages (10, 11) are, in addition, optionally covered by the soldering (8) so as to be gastight.</p> |
