Abstract (en)
[origin: DE19817475A1] The discharge lamp has a gas-filled tubular discharge vessel with three or more elongate electrodes (3,4) which fulfill the equation -s/a is greater than or equal to 0.1, where s is the maximum distance between a connecting line of an electrode pair and the nearest wall of the discharge vessel (2), and a is the mutual separation of the electrode of this electrode pair. An Independent claim is also included for an illumination system using a fluorescent lamp and a pulse voltage source.
