Definitions

  • the invention relates to a high-pressure discharge lamp based on one side the preamble of claim 1.
  • the patent application with the international publication number WO 94/28576 describes a high-pressure discharge lamp, in particular one-sided socketed high-pressure discharge lamp for a motor vehicle headlight, with a discharge vessel sealed at two ends, which is surrounded by an outer bulb.
  • the outer bulb is in the area of the pinch seals, outside the base the discharge vessel melted.
  • the discharge vessel end has a base a tubular extension which, as disclosed in EP 0 455 884 B1, is adjustable Holder part of the base is melted.
  • a disadvantage of this lamp is in that the relatively thin tubular extension in the area between the outer bulb and base is prone to breakage.
  • the published patent application EP 0 588 602 A2 discloses a headlight lamp, the a Discharge vessel, an outer bulb surrounding the discharge vessel and one Has base in which a tubular extension of the outer bulb is arranged is.
  • the lamp is surrounded by a reflector, the light exit opening is closed by a cover plate.
  • European patent application EP 0 580 013 A1 describes a one-sided base High pressure discharge lamp.
  • the discharge vessel of the lamp is using a for high frequency induced heating suitable means in the plastic base the lamp melted down.
  • the published patent application EP 0 321 866 A2 describes a high-pressure discharge lamp with a base on one side, especially for a motor vehicle headlight, with a two-sided sealed discharge vessel, which is also sealed on two sides Outer bulb, the ends of which over the led out of the discharge vessel ends Power supply lines are squeezed tightly, is completely enclosed.
  • the base-side end of the outer bulb is held by a metallic fixing sleeve worn, which in turn is fastened in a base sleeve made of plastic.
  • the assembly of the outer bulb in the base and the fastening of the discharge vessel in the outer bulb are relatively complex here.
  • the high-pressure discharge lamp according to the invention which has a base on one side has a festoon-like, that is, two-sided sealed discharge vessel with a discharge space, a base near and a base distant end. At least the discharge space is enclosed by an outer bulb that ends at the discharge vessel is melted.
  • the two lamp vessels, discharge vessel and outer bulb thus form a structural unit.
  • the Outer bulb melted into an adjustable holder part relative to the base sleeve.
  • the Unit consisting of the discharge vessel and the outer bulb, when the Outer piston are already pre-adjusted in the holder part to ensure that after the adjustment of the holder part in the base sleeve, the discharge arc in the focal point of the headlight reflector.
  • the outer bulb is advantageously included provided a tubular extension that the outer bulb over its base Fusion with the discharge vessel extended, and that in the holder part the base is melted. This makes the distance of the discharge space to the plastic base enlarged and the thermal load on the base reduced. In the melting area, the outer bulb, or its tubular one Extension, a profile on the outer surface that after the melting process improves the adhesion of the outer bulb in the holder part holder.
  • the invention based on a preferred embodiment explained in more detail.
  • the figure shows a cross section through a socket on one side High-pressure discharge lamp according to the preferred embodiment.
  • the single-ended high-pressure discharge lamp has a tubular discharge vessel 1 with a gas-tight closed discharge space 1a, a base near 1b and a base distant 1c Bruising.
  • Two electrodes 2, 3 each protrude into the discharge space 1a via a molybdenum foil melted in gas-tight manner in the squeezing end 1b or 1c 4, 5 with a power supply 6, 7 led out of the pinch end 1b, 1c are electrically connected.
  • the lamp base 8 consists essentially of a base sleeve 8a made of plastic, one arranged inside the base sleeve 8a, adjustable, also made of plastic holder part 8b and one Ceramic cover 8c, which is fastened to the base sleeve 8a by means of metal springs 9 and covers the holder part 8b.
  • the end facing away from the discharge vessel Base sleeve 8a is designed as a plug with two electrical contacts 10a, 10b.
  • the lamp according to the invention has a cylindrical, almost coaxial to the discharge vessel 1 arranged outer bulb 11, the squeezing end 1c remote from the base and to a tubular extension 1d of the base sleeve 8a which extends Discharge vessel 1 is melted.
  • the outer bulb 11 is also with a tubular extension 11a equipped, the tubular extension 1d of the Discharge vessel 1 partially encloses.
  • To base the high-pressure discharge lamp is the tubular extension 11a of the outer bulb 11 in a receptacle of the holder part 8b with the aid of a metal high sleeve integrated in the holder part 8b 12, which is heated with a high-frequency induction signal, melted down.
  • the outer surface of the tubular extension 11a is in the melting area with groove-like depressions 11b, which the adhesive connection between the holder part 8b and improve the outer bulb 11.
  • the holder part 8b has a welding ring 14, which is a high-frequency-induced welding of base sleeve 8a and holder part 8b enables.
  • the near the base running within the tubular extension 1d Power supply 6 is connected to base contact 10b in an electrically conductive manner, while the power supply 7 remote from the base with a parallel to the outer bulb 11 running and returned to the base 8 current return 13 welded is.
  • This current feedback 13 is electrically conductive with the base contact 10a connected and running parallel to the discharge vessel 1 or to the outer bulb 11 Section has ceramic insulation 13a.
  • the weld connection between the current return 13 and the base remote power supply 7 is by a the power supply 7 and the cap 15 fixed to the ceramic insulation 13a Protected plastic or ceramic, which covers the pinch end 1c remote from the base.
