Abstract:
A fluorescent lamp (1) having an at least partially transparent closed, tubular discharge vessel (2) which is filled with a gas filling and made from an electrically nonconducting material, which discharge vessel (2) has on its inner wall at least partially a layer of a fluorescent material or mixture of fluorescent materials (6), and having elongated electrodes (3; 4; 12; 14a-14d) arranged parallel to the longitudinal axis of the tubular discharge vessel (2), at least the electrode(s) of one polarity being separated by a dielectric (2; 13; 15a-15d) from the interior of the discharge vessel, characterized in thatat least one electrode (4; 12; 14a-14d) is arranged on the inner wall of the discharge vessel (2),the at least one inner wall electrode (4; 12; 14a-14d) is additionally further constructed as a feedthrough (10) and the latter, in turn, is further constructed as an external supply lead (11), that is to say that each inner wall electrode (4), the associated feedthrough (10) thereof and associated external supply lead (11) are constructed in each case as functionally differing subregions of a unilateral common structure (4, 10, 11) resembling a conductor track.
