Definitions

  • the invention relates to a high-pressure discharge lamp with a base on one side, according to the preamble of patent claim 1.
  • Patent EP 0 455 884 B1 discloses an electric lamp with a base on one side, which has a lamp bulb with an end on the base side and an end remote from the base.
  • the base-side end of the lamp bulb is equipped with a tubular extension which is melted into an adjustable holder part arranged inside the base.
  • the lamp is preferably a high-pressure discharge lamp with a base on one side, in particular a motor vehicle discharge lamp, and the lamp bulb is the discharge vessel of this lamp.
  • the lamp described here has no outer bulb that reduces the UV radiation transmitted by the discharge vessel.
  • the as yet unpublished patent application with the international file number PCT / DE 94/00600 describes a high-pressure discharge lamp, in particular a single-ended high-pressure discharge lamp for a motor vehicle headlight, with a double-ended discharge vessel which is surrounded by an outer bulb.
  • the outer bulb is fused to the discharge vessel in the area of the pinch seals, outside the base.
  • the base-side discharge vessel end has a tubular extension which, as disclosed in EP 0 455 884 B1, is melted into the adjustable holder part of the base.
  • a disadvantage of this lamp is that the relatively thin tubular extension in the area between the outer bulb and base is prone to breakage.
  • the published patent application EP 0 321 866 A2 describes a high-pressure discharge lamp with a base on one side, in particular for a motor vehicle headlight, with a discharge vessel which is sealed on both sides and which is completely enclosed by an outer bulb which is likewise sealed on both sides and whose ends are squeezed tightly over the current leads led out of the discharge vessel ends.
  • 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 is capped on one side, has a festoon-like, that is to say double-sealed discharge vessel with a discharge space, an end near the base and an end remote from the base. At least the discharge space is enclosed by an outer bulb which is fused to the ends of the discharge vessel.
  • the two lamp vessels, the discharge vessel and the outer bulb thus form a structural unit.
  • the outer bulb is melted into a holder part that is adjustable relative to the base sleeve. In this way, an increased break resistance compared to the prior art and a simplified and improved base of the lamp is achieved.
  • the outer bulb is advantageously melted into the holder part using an agent suitable for high-frequency-induced heating.
  • the unit consisting of the discharge vessel and the outer bulb, can already be pre-adjusted when the outer bulb melts into the holder part, in order to ensure that after the holder part has been adjusted in the base sleeve, the discharge arc lies in the focal point of the headlight reflector.
  • the outer bulb is advantageously provided with a tubular extension which extends the outer bulb beyond its base-side fusion with the discharge vessel, and which is fused into the holder part of the base. As a result, the distance between the discharge space and the plastic base is increased and the thermal load on the base is reduced.
  • the outer bulb, or its tubular extension has a profile on the outer surface which improves the adhesion of the outer bulb in the holder part receptacle after the melting process.
  • the invention is explained in more detail below on the basis of a preferred exemplary embodiment.
  • the figure shows a cross section through a high-pressure discharge lamp based on one side according to the preferred exemplary embodiment.
  • the high-pressure discharge lamp based on one side has a tubular discharge vessel 1 with a gas-tightly closed discharge space 1a, a base-near 1b and a base-distant 1c squeezing end.
  • Two electrodes 2, 3 protrude into the discharge space 1a, each of which is electrically conductively connected via a molybdenum foil 4, 5 which is melted gas-tight in the squeezing end 1b or 1c, to a power supply line 6, 7 led out of the squeezing end 1b, 1c.
  • the lamp base 8 essentially consists of a base sleeve 8a made of plastic, an adjustable holder part 8b arranged inside the base sleeve 8a, also made of plastic, and a 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 of the base sleeve 8a facing away from the discharge vessel is designed as a plug with two electrical contacts 10a, 10b.
  • the lamp according to the invention has a cylindrical outer bulb 11 which is arranged almost coaxially to the discharge vessel 1 and which is fused to the pinch end 1c remote from the base and to a tubular extension 1d of the discharge vessel 1 which extends into the base sleeve 8a.
  • the outer bulb 11 is also equipped with a tubular extension 11a, which partially surrounds the tubular extension 1d of the discharge vessel 1.
  • the tubular extension 11a of the outer bulb 11 is melted into a receptacle in the holder part 8b with the aid of a metal high-pressure sleeve 12 which is integrated in the holder part 8b and is heated with a high-frequency induction signal.
  • the outer surface of the tubular extension 11a is provided in the melting area with groove-like depressions 11b, which improve the adhesive connection between the holder part 8b and the outer bulb 11.
  • the holder part 8b has a welding ring 14, which enables high-frequency-induced welding of the base sleeve 8a and holder part 8b.
  • the power supply 6 close to the base and running within the tubular extension 1d is electrically conductively connected to the base contact 10b, while the power supply 7 remote from the base is welded to a current return 13 running parallel to the outer bulb 11 and returned to the base 8.
  • This current feedback 13 is electrically conductively connected to the base contact 10a and its parallel to the discharge vessel 1 or to the outer bulb 11 Section has ceramic insulation 13a.
  • the welded connection between the current return 13 and the power supply 7 remote from the base is protected by a plastic or ceramic cap 15 which is fixed to the power supply 7 and the ceramic insulation 13a and which covers the pinch end 1c remote from the base.
