Title (EN) BACKWOUND ELECTRODE COIL FOR ELECTRIC ARC TUBE OF CERAMIC METAL HALIDE LAMP AND METHOD OF MANUFACTURE
(FR) BOBINE D'ELECTRODE REBOBINEE POUR TUBE A ARC ELECTRIQUE DE LAMPE A HALOGENURE DE METAL CERAMIQUE ET SON PROCEDE DE FABRICATION
Abstract: front page image
(EN)Tips (34) for electrodes that are adapted to be applied to a ceramic halide lamp are formed by backwinding tungsten wire into a coil (42) onto a tungsten shank (40). The outer diameter (D3) of the coil of tungsten wire is maintained sufficiently small so that the electrode tips can be inserted through openings in the legs of the electric arc tube of the ceramic halide lamp and the tungsten coil (42) positioned within the hollow interior of the electric arc tube.
(FR)L'invention concerne des pointes d'électrodes destinées à être appliquées à une lampe à halogénure céramique qui sont formées par rebobinage de câble en tungstène en bobine sur une tige en tungstène. Le diamètre extérieur de la bobine de câble en tungstène est maintenu suffisamment petit de façon que les pointes d'électrodes puissent être introduites à travers des ouvertures dans les branches du tube à arc électrique de la lampe à halogénure céramique et la bobine en tungstène placée à l'intérieur creux dudit tube à arc électrique.
