Abstract

PURPOSE:To reduce the flickering phenomenon of a positive column by applying a magnetic field, which intersects the electric field of a discharge tube, over almost the entire area of the positive column. CONSTITUTION:A filament 5 which is supported by a lead wire is fixed to a stem 6, which is fused and fixed to each end of a glass tube 3 the inner wall of which is coated with a fluorescent body 2. After the tube 3 is subjected to vacuum exhaustion, it is charged with a rare gas. After that, a beltlike instantaneous lighting electrode 7 is attached to the outer surface of a fluorescent discharge tube 1, thus a rapid-start fluorescent discharge tube 1a being constituted. The instantaneous lighting electrode 7 is made of a conductive magnetic body which is magnetized, and a magnetic field H which is produced by the instantaneous lighting electrode 7 intersects the electric field of the fluorescent discharge tube 1.
