Abstract

PURPOSE:To prevent the scattering loss of emitter substance, lengthen the life of filament, and shorten the time of starting and lighting by a method in which C- shaped auxiliary anodes opening on a stem side are faced each other through a fine gap and the periphery of a filament is surrounded by the auxiliary anodes. CONSTITUTION:A pair of auxiliary anodes 4, 5 are formed into a dome shape with an opening 11 by bending downwardly Ni or Fe plate in an almost -shaped insection, and connected and fixed to each of internal conductors 1, 2 by supporting wires, 8, 9. Then, the auxiliary anodes 4, 5 connected electrically with conductors 1, 2 with the supporting wires in such a way that they are faced each other with a fine gap 6 are covered on the periphery of a filament 6 with an aperture left. Thus, the scattering loss of emitter substance can be pevented, the life of the filament can be lengthened, and the time of starting and lighting can be shortened.
