Leuchtstofflampe und Verfahren zu ihrem Betrieb

摘要

The invention relates to a fluorescent lamp (1), with a tubular discharge vessel (2) filled with inert gas, and a layer of fluorescent material (6), comprising long electrodes (3; 4; 12; 14a-14d) which are positioned parallel to the longitudinal axis of the tubular discharge vessel (2). At least one electrode (3; 4; 12; 14a-14d) is positioned on the internal wall of the discharge vessel (2). Said tubular discharge vessel (2) is sealed at one or both ends with a stopper (8) and by means of soldering (9), so that it is gas-tight. The at least one internal wall electrode (4) also leads outside via said soldering in such a way that it remains gas tight. Alternatively or additionally, at least one electrode (16) is positioned inside the wall of the discharge vessel (2). A maximum of the entire interior diameter can be used as discharge distance, depending on the positioning of the corresponding counter electrode. High luminance levels are achieved as a result of the large and also constant discharge distance throughout the length of the discharge tube. The lamp is suitable for a pulsed, dielectrically inhibited discharge.
