Definitions

  • the invention relates to a method for producing an electric incandescent lamp according to the preamble of claim 1.
  • Such a manufacturing process is for example in the German patent DE 22 43 717 discloses.
  • This patent describes a two-filament halogen incandescent lamp with a dimming cap and one arranged in the dimming cap Filament.
  • the anti-glare cap has a cross rib Welding lug.
  • the filament ends are each wrapped in a metal foil.
  • the filament is fixed to the anti-glare cap here by one of the from the metal foil enclosed coil ends by spot welding the cross rib is attached.
  • German patent specification DD 224 445 A1 describes a manufacturing process for a light bulb with one end of a filament in a V-shaped groove arranged the flat part of a dimming cap and welded to the dimming cap is.
  • the manufacturing method according to the invention enables a filament end to be more easily attached to the anti-dazzle device, because at least one of the metal foils surrounding the filament ends can now be saved.
  • the inventive fusion of the filament end in a notch at the edge of the anti-dazzle device can be carried out both for uncoiled and for coiled filament ends.
  • the material of the anti-dazzle device is advantageously melted on both sides of the notch. This ensures complete embedding of the filament end in the re-solidified melt of the anti-dazzle device.
  • the anti-dazzle device is advantageously formed from a metal sheet so that it can serve as an electrical power supply for the filament connected to the anti-dazzle device.
  • the notch on the edge of the anti-dazzle device is made by two adjacent, protrusions formed by the anti-dazzle device which have a V-shaped or U-shaped space. These two exposed protrusions can be heated and melted with comparatively little energy using a LASER.
  • the production method according to the invention is particularly suitable for the production of two-filament halogen incandescent lamps which are used as light sources in motor vehicle headlights.
  • the manufacturing method according to the invention is based on a Two-filament halogen lamp, a so-called H4 lamp explained become.
  • the structure of the H4 lamp is shown schematically in FIG. 3.
  • the two-filament halogen incandescent lamp shown in FIG. 3 has one side densely squeezed lamp bulb 1 made of tempered glass.
  • the press seal 10 of the lamp bulb 1 is in a cup-like holder part 2 made of stainless steel clamped fixed.
  • the holder part 2 forms together with the base sleeve 3 and the adjustment plate 4 formed thereon and with the base stone 5 the lamp base.
  • the holder part 2 is punched out from the adjustment plate 4 and upwardly curved welding lugs 13 with the adjustment plate 4 welded.
  • incandescent filaments within the lamp bulb 1 6, 7, which protrude over a total of three from the pinch seal 10 and fused-in power supplies between two quartz beams 11 8 are each electrically conductively connected to a contact tab 9.
  • a the filament 6 is provided with a dimming cap 12.
  • the filament holder of an H4 lamp To manufacture the filament holder of an H4 lamp according to the invention Manufacturing process, one is made from a metal sheet, preferably molybdenum sheet, prefabricated trough-like anti-dazzle device 20 provided ( Figure 2).
  • This anti-dazzle device 20 has two at its edge adjacent, tooth-like protrusions 21, 22, which are together a space formed as a V-shaped or U-shaped notch 23 form.
  • the anti-dazzle device 20 also has one with a transverse rib 24 provided welding flag 25.
  • the bottom of the anti-dazzle device 20 is with equipped two humps 27.
  • the ends 30a, 30b of the low beam 30 are each with a Molybdenum foil 36 wrapped and with the cross rib 24 on the welding lug 25 of the anti-dazzle device 20 or with one end of the power supply wire 33 spot welded so that the filament 30 in the anti-dazzle device 20 is arranged.
  • a Molybdenum foil 36 wrapped and with the cross rib 24 on the welding lug 25 of the anti-dazzle device 20 or with one end of the power supply wire 33 spot welded so that the filament 30 in the anti-dazzle device 20 is arranged.
  • To fix the arranged below the anti-dazzle device 20 High beam 31, one end 31a of the high beam 31 in the notch 23 formed by the tooth-like projections 21, 22 and then the two tabs. 21, 22 each with the help of a LASER beam acting briefly on the two projections 21, 22 heated and melted simultaneously, so that the helix 31a of the Melt is wetted and completely enclosed.
  • the invention is not limited to the exemplary embodiment explained in more detail.
  • the one welded to the transverse rib 24 can also be used Filament end 30a of low beam filament 30 in the same way as that End 31a of the female light filament 31 is fused to the edge of the anti-dazzle device 20 become.
  • the application of the invention Fusion of filament end and anti-glare cap not on two-filament halogen lamps limited.
