Definitions

  • the invention relates to an electric lamp with a lamp base, which is fastened via a metal cap that engages the lamp pinch foot, is inserted into the base sleeve and is firmly connected to it.
  • the base can have a corresponding number of ground contacts. If there is only one central contact with the ground, the base sleeve must be included as a side contact and the end of the current supply wire in question must be guided between the metal cap and the base sleeve and fixed there.
  • the object of the invention is to ensure an adjustment of the lamp even when the base sleeve has to serve as a side contact and the above measure is necessary for this.
  • the metal cap is smaller in diameter than the minimum diameter of the base sleeve and is provided with an edge groove in which the power supply wire end placed between the metal cap and base sleeve runs.
  • the lamp in FIG. 1 a halogen incandescent lamp, has a lamp bulb 1 made of high-melting glass.
  • a tungsten filament 2 serves as the luminous element.
  • the bulb 1 is filled with inert gas with halogen addition and is closed at the lower end by squeezing.
  • Power supply wires 3 lead through the pinch foot 4 to the outside.
  • a metal cap 5 engages on the pinch foot 4.
  • the pinch foot 4 is received from its opening 6. With inwardly bent tabs 7 (FIG. 3), the metal cap 5 is supported on projections 8 of the crushed glass.
  • the metal cap 5 is cylindrical. Also cylindrical is the lamp base 9, in the metal base sleeve 10 of which the metal cap 5 is inserted with a predetermined play.
  • the base of the sleeve forms a base stone 11 and a central base contact 12.
  • the base sleeve 10 is a side contact. Accordingly, one of the two power supply wires 3 leads to the ground contact 12, the other, however, is guided with its end 3a between the metal cap 5 and the base sleeve 10.
  • the wire end 3a is inserted into an edge groove 13 of the metal cap 5.
  • the edge groove 13 runs approximately parallel to the base axis.
  • Another edge groove 14 is provided which is diametrically opposite the first.
