Definitions

  • the invention relates to an electric lamp according to the preamble of the claim 1 and a lighting device with such a lamp.
  • Such an electric lamp is for example in the international patent application WO 97/25733 discloses.
  • This laid-open specification describes an electrical one Incandescent lamp, in particular a motor vehicle headlight lamp, with an in a glass lamp bulb enclosed and a lamp base made of metal and plastic parts.
  • the gas-tight one Pinch base of the lamp bulb is fixed in a metallic holder part, which in turn directly or via an intermediate ring with a metallic, ring-shaped Carrier sleeve is connected.
  • the metallic carrier sleeve is in the same with the electrical Connections of the lamp equipped plastic base part of the lamp base anchored.
  • a reflector To mount the lamp in the lamp socket Opening of a reflector has the annular support sleeve three in one plane arranged reference lugs distributed equidistantly over the circumference of the carrier sleeve, which engage in the lamp mounting opening of the reflector, and one radially after external pressure spring, with a clamp on the edge of the lamp mounting opening of the reflector.
  • the carrier sleeve has below the three reference lugs one point of contact with the edge of the lamp mounting opening of the reflector. One of these points of contact is formed by the pressure spring.
  • the three reference lugs are on the inside of the reflector.
  • the seal the lamp mounting opening of the reflector is designed as a lamp holder by means of a silicone sealing ring, which is between the outside of the reflector and the plastic base part of the lamp base is arranged.
  • This one made of metal and
  • the lamp base constructed of plastic parts is guaranteed on the one hand by its metallic Holder parts for the lamp bulb an exact adjustment of the filament position compared to the reference plane defined by the three reference lugs and by its plastic base part a satisfactory sealing of the lamp base and of the reflector against moisture.
  • this affects the manufacture of the reflector forming ridge on the outer edge of the lamp mounting opening of the Reflector the installation position of the lamp unfavorable and causes an undesirable Misalignment of the filament relative to the optical axis of the reflector.
  • the object of the invention to provide an electric lamp with an improved To provide lamp bases, where the disadvantage of lamps according to the state technology is avoided.
  • the lamp of the invention despite any burrs on the lamp mounting opening of the reflector, with the correct position of the filament with respect to the optical axis of the reflector be mountable.
  • the electric lamp according to the invention has a lamp base, a translucent Lamp bulb and at least one enclosed by the lamp bulb Illuminant.
  • the lamp base has a metallic holder part in which the lamp bulb is fixed, and a metallic, ring-shaped connected to the holder part Carrier sleeve and a provided with the electrical connections of the lamp Plastic base part in which the carrier sleeve is anchored.
  • the ring-shaped carrier sleeve has three in a common, perpendicular to the ring axis Level reference lugs that engage in a lamp socket Serve mounting opening of a reflector, and one acting radially outwards Pressure spring, which is used to fix the lamp in the form of a lamp holder Opening of the reflector is used, the pressure spring below a first Reference nose is arranged.
  • the annular carrier sleeve on the outside, one below each of the second and third reference lugs recess or a recess spaced from the reference lugs. Thereby If there is any burr on the lamp mounting opening of the reflector there are no points of contact with the lamp base.
  • a misalignment of the position of the lamp with respect to the reflector axis is prevented in this way because the three points of contact the support sleeve with the edge of the lamp mounting opening of the reflector outside the area of the lamp mounting opening, which may have a burr are arranged.
  • the lighting system according to the invention has in addition to the lamp with the Features described above, a reflector, the one facing the lamp bulb Inside of the reflector and an outside of the reflector facing away from the lamp bulb as well as a light exit opening and a lamp socket Lamp mounting opening has.
  • This lamp mounting opening is through one Border bounded by an inner edge on the inside of the reflector and on the outside of the reflector has an outer edge.
  • the lamp's reference lugs grip into the lamp mounting opening and lie on the inside of the reflector on the reflector on.
  • the pressure spring lies on the edge of the lamp mounting opening and defines a first point of contact between the lamp base and the edge the lamp mounting opening.
  • the carrier sleeve is below the second and third reference lug on the edge of the mounting opening and defines two more Points of contact between the lamp base and the edge of the lamp mounting opening.
  • the depressions in the outside of the carrier sleeve or the Recesses of the support sleeve are arranged so that they are at the same level with the Outside edge of the edge of the lamp mounting opening are arranged.
  • the preferred embodiment of the invention is a Single-filament halogen lamp for use in a motor vehicle headlight is provided.
  • This lamp has a glass, essentially cylindrical Lamp bulb 10 with a gas-tight squeeze foot 10a.
  • the Dome 10b of lamp bulb 10 is provided with a light-absorbing coating.
  • a light source that is aligned parallel to the lamp bulb axis serves as the light source Incandescent filament 11, which is electrically conductive with two led out of the squeezing foot 10a, Power supply lines 12, 13 made of molybdenum wire are connected.
  • the squeezing foot 10a of the lamp bulb 10 is in a metallic holder from the cup-like holder part 14a, the intermediate ring 14e and the annular Carrier sleeve 14b is fixed.
  • the lamp base is also provided with the electrical connections 16, 17 of the lamp Plastic base part 15 in which the annular metallic support sleeve 14b is anchored.
  • the carrier sleeve 14b has three reference lugs lying in one plane 14c and a pressure spring 14d for mounting the lamp in the reflector 20 a motor vehicle headlight.
  • the reflector 20 is sealed by means of a silicone sealing ring 19 which on the outer wall 20b of the reflector 20 and abuts the plastic base part 15.
  • the construction of the lamp is shown in FIG of the preferred embodiment and their use in a headlight schematically shown.
  • FIGS 2 and 3 show details of the arrangement of the lamp in the reflector 20 of the Automotive headlights.
  • the three reference lugs 14c engage in the lamp holder trained mounting opening 21 of the reflector 20 and lie on the inside 20a of the reflector 20. They 14c are equidistant over the circumference of the ring-shaped Carrier sleeve 14b distributed.
  • the pressure spring 14d of the carrier sleeve 14b is below a first reference lug 14c and resiliently on the edge 22 of the Lamp mounting opening 21 on.
  • Below the other two reference lugs 14c the outside of the carrier sleeve 14b each has a recess 14f.
  • the wells 14f are each at a distance of approximately 2.4 mm below the reference lugs 14c arranged.
  • the reflector wall has in the area of the lamp mounting opening 21 a thickness of 3 mm.
  • the Recesses 14f in the outside of the carrier sleeve 14b are at the same height the outer edge 22a2 of the opening edge 21 is arranged.
  • the edge 22 of the lamp mounting opening has other reference lugs 14c 21 of the reflector 20 each have a prismatic contact surface 22a.
  • the outside the support sleeve 14b of the lamp base lies on these two prismatic ones Contact surfaces 22a with a press fit.
  • the clamping effect is by means of Pressure spring 14d generated.
  • the contact surfaces between the support sleeve 14b and contact surfaces 22a are located below the reference lugs 14c and above the depressions 14f. Because of the depressions 14f, the one that may have a burr is Outer edge 22a2 of the edge 22 of the mounting opening 21 without contact to the lamp base and in particular to the support sleeve 14b.
  • the carrier sleeve 14b instead of the two depressions 14f also have a ring segment-shaped groove in its outer wall, which in the area of prismatic contact surfaces 22a arranged at the same level with the outer edge 22a2 is.
  • the carrier sleeve 14b can also have cutouts, that is, have openings in the carrier sleeve wall.
