A halogen incandescent lamp, in particular a miniature halogen incandescent lamp with an electrical power consumption of at most 10 W, that is suitable for use in a pocket lamp. The outside diameter of the lamp bulb is 3.0 mm to 6.2 mm, and the sections ( ) arranged in the interior ( ) of the lamp bulb ( ), of the supply leads ( ) for the incandescent filament ( ) are constructed as flattened wires in order to minimize shading effects.

Halogen incandescent lamp

The invention relates to the fastening of incandescent coil filaments to current lead-in wires in electric lamps. One end (,) of the current lead-in wires is flattened and U-shaped. The U-shaped segment (,) of the current lead-in wire forms a gap-like seat (,) for a coiled incandescent coil-filament end (,), the gap width of which is smaller than the outside diameter of the incandescent coil-filament end (,).
