Abstract
The halogen incandescent lamp has a tipless lamp vessel (1) having a first seal (3), in which a current supply conductor (7) with a foil-shaped part (9) of small width (w.sub.1) is accommodated, and a second seal (4), in which a current supply conductor (8) with a foil-shaped part (10) of larger width (w.sub.2) is accommodated. This construction permits a simple method of manufacturing the lamp, in which the tube from which the lamp vessel (1) is formed has a constriction which allows the first current supply conductor (7) and the filament (5) to pass, but stops the foil-shaped part (10) of the second current supply conductor (8) and holds the filament positioned in axial direction in the tube.
