Abstract (en)
The lamp has a lamp vessel that is axially aligned with an incandescent filament (3) made from tungsten, and power supply wires (4, 5) for the incandescent filament. One of the power supply wires is provided with a hole in which an outgoing filament line (31) of the incandescent filament is fixed. The hole extending transversely relative to a longitudinal direction of the power supply wires is produced by a laser.
