Abstract

1475739 Electric incandescent lamps; discharge lamps THORN ELECTRICAL INDUSTRIES Ltd 20 Aug 1975 [19 Sept 1974] 40961/74 Headings H1F and H1D In a method of making an incandescent filament or discharge lamp having an internal sheet metal support with at least two legs such as 11, 12, 13 for supporting filaments 14, 15 or other internal components such as a reflector 16, a pair of bridging strips 23, 24 or 25, 26 is formed integrally with the support between each pair of adjacent legs to provide an initial connection between the legs and, after the support has been embedded in the press seal 19 of the lamp, the strips are severed by passing a current through them sufficient to fuse the strips without damaging the rest of the lamp.
