ABSTRACT:
The electric lamp has a quartz glass lamp vessel (1) in the wall (2) of which metal foils (4) are embedded to which internal current conductors (5) and to a flat end portion (8) of which external current conductors (6) are connected. The end portions (8) are eccentrically flattened by means of stamps (20, 21) so as to have a plane (7) to which the center line (9) of the external current conductor (6) is substantially coincident. The occurrence of cracks and facture of the metal foils (4) is thereby counteracted.
