Definitions

  • the invention relates to an electric incandescent lamp according to the preamble of patent claim 1.
  • the electric incandescent lamp according to the invention has power supply wires for at least one filament, wherein according to the invention at least one power supply wire is provided with a bore in which a helical departure of the at least one filament is fixed.
  • the helical departure of the at least one filament can be welded directly to the power supply wire without the use of the molybdenum tubes according to the prior art.
  • a halogen incandescent lamp for a vehicle headlight in particular a H7 lamp.
  • This lamp has a glass lamp vessel 1, which is provided at one end with a metallic lamp cap 2.
  • an axially aligned incandescent filament 3 is arranged made of tungsten, the filament outlets 31, 32 are each welded to a power supply wire 4 and 5 made of molybdenum.
  • the power supply wires 4, 5 have a thickness or a diameter of 0.7 millimeters and are led out of the sealed, provided with the lamp base 2 end of the lamp vessel 1 and each connected to an electrical terminal 6 or 7 of the lamp cap 2.
  • the incandescent filament 2 For fixing the incandescent filament 2 to the first power supply wire 4, this has at one end in its longitudinal direction extending bore 40 ( Figure 2) with a diameter of 0.5 millimeters, in which the first filament outlet 31 of the filament 2 and arranged by a Laser welding is fixed.
  • the second filament outlet 32 of the filament 2 is disposed in the bore 50 of the second power supply wire 5 and fixed by means of a laser weld.
  • the bore 50 ( Figure 1) also has a diameter of 0.5 millimeters and extends transversely to the longitudinal direction of the power supply wire 5. Both holes 40, 50 were generated by means of a laser.
  • the invention is not limited to the embodiment explained in more detail above.
  • the bores or holes 40, 50 can also be generated by means of an electron beam or by spark erosion.
  • the invention is not limited to vehicle lamps, but also to other types of
