  • Electric lamp having a current lead-in wire with a flattened U-shaped end segment
    Patent number: 6191526
    Abstract: The invention relates to the fastening of incandescent coil filaments to current lead-in wires in electric lamps. One end (41) of the current lead-in wires is flattened and U-shaped. The U-shaped segment (41) of the current lead-in wire forms a gap-like seat (45) for a coiled incandescent coil-filament end (3a), the gap width of which is smaller than the outside diameter of the incandescent coil-filament end (3a).
