Abstract

Improvements introduced in the manufacture of incandescent lamps, of the type comprising an evacuated ampule, of glass with a high content of silica, hermetically closed, inside which filament means are supported and in which part of the collapsed neck connection means are provided, in sealing relation with crushed glass, intended to join the external conductors of current supply with the inner conductors of the lamp, characterized in that said connection means comprise a sheet of refractory metal, of greater thickness, than the usual one, with a thinning of part of its length, this part of its length destined to be in contact with the crushed glass of the neck part of the lamp, so that the part of greater width of the sheet protrudes to the outside of the ampule while that the inner feed conductor is welded to the end of the thinned part and protrudes into the bulb of the lamp, and because said thinning of the connecting sheet is carried out by dissolving electrochemically the metal in said part of the length of said starting sheet.
