Definitions

  • the invention relates to a high-pressure gas discharge lamp for a lighting device, in particular for a headlight of a motor vehicle, with an ignition electronics, which is arranged within a base housing having an upper part and a lid.
  • a base housing for a high-pressure gas discharge lamp which consists of a lid and a top.
  • a lid For the installation of a high-pressure gas discharge lamp, it may be necessary to store high-voltage-carrying contacts accessible within the base housing of the ignition electronics. By means of the lid, this area can be closed high-voltage safe.
  • both the wall thickness and the creepage distance between the high-voltage contact and the environment must be sufficiently dimensioned so that the high voltage does not break through.
  • the high-pressure gas discharge lamp for a lighting device in particular for a headlight of a motor vehicle, cooperates with an ignition electronics, which is arranged within a base housing, that the base housing has a top and a lid, wherein the upper part is designed with an opening, within this is a high-voltage connection between the high pressure gas discharge lamp and the ignition electronics is that the lid protrudes into the opening and the opening closes insulating, and that the mutually facing surfaces of the upper part and the lid form a labyrinth, which is interrupted by an insulating element.
  • the insulation element allows for a shortening of the labyrinth and on the other hand, an improved insulation of the high-voltage connection between the lid and the upper part. As a result, a space-saving construction of the high-pressure gas discharge lamp is achieved.
  • the insulation element forms a circumferentially closed ring. It is advantageous here if the circumferentially closed ring has a circle, an oval or a rectangular basic shape.
  • the shape of the insulation element depends on the circumference of the labyrinth.
  • the insulation element is designed with at least one of the following cross sections: round, oval or angular.
  • the respective cross section of the insulation element is dependent on the contour of the region to be sealed and / or its positioning within the labyrinth.
  • the isolation element is designed as an elastic sealing ring. It has proved to be particularly advantageous if the sealing ring is made of an elastic polymer.
  • the sealing ring made of an elastic polymer can adapt positively by deformation of its adjacent surface within the labyrinth and thus form a high-voltage-proof shield.
  • the insulation element can be arranged on the upper part and / or on the cover. It has proven to be advantageous in this case if the insulation element is molded directly onto the upper part and / or on the cover. By injecting the insulation element, a reliable fixation of the insulation element can be ensured within the labyrinth, at the same time the ease of assembly is increased. Alternatively, sticking of the insulating element would also be conceivable.
  • the upper part and / or the cover is / are configured within the labyrinth with a groove in which the insulation element is detachably fastened.
  • the geometry of the groove is in this case designed such that the insulating element is held positively in the groove.
  • the contour of the insulation element is designed like a louver. Due to a lamellar configuration of the insulation element acts in an end position of the lid and the upper part of a force within the labyrinth, which holds the lid on the upper part.
  • the insulation element can be designed either single or multi-lamellar. It is particularly advantageous if the insulation element acts within the labyrinth with a force both on the cover and on the upper part. By this isolatorische measure an improvement of the shielding can be achieved within the labyrinth.
  • the insulating member may have a cross-sectional diameter of 0.5 mm ⁇ x ⁇ 4 mm. The diameter of the insulating element can be dependent both on the elasticity of the insulating element and on the diameter of the labyrinth.
  • a further inventive measure provides that at least two isolation elements are arranged within the labyrinth.
  • the arrangement of at least two isolation elements within the labyrinth increases the shielding at the same labyrinth length.
  • high-pressure gas discharge lamps with two or three insulation elements have proven to be a particularly good compromise between the number, cost and effectiveness of the insulation elements.
  • the insulation elements are interconnected.
  • a cohesive connection in particular by gluing and / or welding of the individual insulation elements is conceivable.
  • Particularly advantageous is the connection of the insulation elements by means of a carrier element.
  • the carrier element can be arranged circumferentially in the upper part and / or on the lid.
  • the insulation element can be arranged on and / or on the carrier element.
  • the insulation elements and the support element can be made of the same material and / or molded onto the upper part and / or the cover. All features and details of the insulation element with respect to arrangement, design and material selection also apply to the support element.
  • the carrier element additionally contributes to preventing a breakdown of the high voltage from the high-voltage-carrying connection.
  • the insulation element is arranged in a channel of the labyrinth running in the direction of closure of the cover.
  • the insulation element is arranged in a channel of the labyrinth running in the direction of closure of the cover.
  • the upper part may have a first collar element which surrounds the opening on the circumferential side.
  • a base element can be arranged within the opening, which extends against the closure direction of the lid within the opening. At the free end of the base element, the high-voltage-carrying connection can run.
  • a closure element corresponding to the opening is arranged on the cover.
  • the lid may have a second collar element. It may be useful if the second collar element surrounds the closure element in an annular manner. In an end position of the lid and the upper part both enclosing the second collar element and the closure element by the first collar element, as well as a toothed engagement of the first collar element between the second collar element and the closure element is conceivable. It may be useful that the shape of the first collar element corresponds to the shape of the second collar element and / or the closure element.
  • FIG. 1 shown high-pressure gas discharge lamp 8 has a base housing 1,2 with an upper part 1 and a cover 2.
  • the upper part 1 is configured with an opening 1.1 within which a high-voltage-carrying connection 4 is mounted.
  • the high-voltage-carrying connection 4 mounted inside the opening 1.1 establishes a connection by means of a contact bridge 4.3 between a first contact 4.1 and a second contact 4.2.
  • the high-pressure gas discharge lamp 8 is connected via the contact bridge 4.3 with the second contact 4.2 by means of the first contact 4.1, which establishes the connection to an ignition electronics 9, which is located within the upper part 1 of the base housing 1.2.
