Definitions

  • the invention relates to an electric lamp according to the preamble of claim 1.
  • Such an electric lamp is for example in the international patent application WO 97/40521.
  • This publication describes an electrical Incandescent lamp, in particular a motor vehicle headlamp, with an in an incandescent filament enclosed in a glass lamp bulb and a metal filament and plastic parts existing lamp base.
  • the gas-tight sealed End of the lamp bulb is fixed in a metallic holder, which in turn the provided with the electrical connections of the lamp plastic base part is anchored.
  • the led out of the lamp bulb, connected to the filament Power supply lines are in the interior of the plastic base part with the welded as contact lugs formed electrical terminals of the lamp.
  • For welding power supply and contact lug have the tabs in each case a bore through which passed the corresponding power supply is.
  • the passed power supply ends are with the contact lug welded.
  • the interior of the plastic base part is with a lid locked.
  • the Lamp socket hose-like silicone parts, through which the power supply leads are, and the press-fitted in the passages of Kunststoffsokkelteil are arranged for the power supply lines.
  • the press fit is with the help of Produces contact flags that exert a pressure on the silicone tubes.
  • the electric lamp according to the invention has a lamp base, a translucent Lamp bulb, at least one enclosed by the lamp envelope Light source, at least two led out of the lamp envelope power supply wires to the power supply of the at least one lamp and a Holder for the lamp bulb and one with the as at least two contact lugs trained electrical connections of the lamp provided plastic base part, in which the holder is anchored.
  • at least two contact lugs each have a groove in each of which a power supply wire by a welded connection with the corresponding contact lug is fixed.
  • the at least two contact lugs according to the invention with Means provided for threading the power supply wires in the respective groove.
  • the lamp cap also has at least one for carrying out the welding the power supply wires with the tabs serving breakthrough.
  • the above-mentioned features of the lamp according to the invention make it possible to Injecting tabs into the plastic base and additional means for sealing the lamp cap against the ingress of atmospheric moisture, such as For example, silicone tubing or potting compound to dispense. Besides, too no lid required to close the socket interior.
  • the welded joint between power supply wires and tabs takes place in the inventive Lamp, for example with the help of a laser, through a tiny Breakthrough in the lamp base.
  • the aforementioned breakthrough is advantageously in the holder and not arranged in the sealed plastic base part. advantageously, be used for the preparation of the above-mentioned weld, because the lower melting temperature, the contact lugs made of sheet steel and not heating the power supply wires made of molybdenum.
  • the means for threading the power supply wires advantageously have for each groove on two webs, which bound the groove laterally, wherein the groove facing Edge of at least one of these webs is provided with a bevel.
  • Particularly preferred embodiment of the invention have the groove facing Edges of both webs each have a slope. These slopes ensure during lamp assembly, an automatic, trouble-free threading of the power supply wire ends into the grooves of the contact lugs.
  • the shorter of the two webs advantageously has a smaller width than the longer bridge on.
  • the preferred embodiment of the invention is a Single-filament halogen bulb suitable for use in a motor vehicle headlight is provided.
  • This lamp has a glassy, substantially cylindrical Lamp bulb 10 with a gas-tight sealed squeezing 10a. Of the Dom 10b of the lamp bulb 10 is provided with a light-absorbing coating.
  • the light source is a parallel to the lamp bulb axis aligned Incandescent filament 11, the electrically conductive with two led out of the squeezing 10a, Molybdenum wire existing power supply wires 12, 13 connected is.
  • the presser 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 also provided with the electrical terminals 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 14 c and a pressure spring 14 d for mounting the lamp in the reflector 20 a motor vehicle headlight.
  • the sealing of the reflector 20 by means of a silicone sealing ring 19 which on the outer wall of the reflector 20 and at the plastic base part 15 is applied.
  • Figure 1 the structure of the lamp according to the preferred embodiment and its use in a headlight schematic shown.
  • the electrical connections 16, 17 of the lamp consist of two metallic contact lugs 16, 17, each welded to one of the power supply wires 12, 13 are (not shown in Figure 1).
  • the contact lugs 16, 17 are made of a Made of sheet steel and injected into the plastic base part 15 of the lamp cap. They 16, 17 each consist of an L-shaped sheet steel.
  • One each Leg 16a, 17a of the L-shaped contact lugs 16, 17 is formed as a plug contact, while the other leg 16b, 17b is provided with a groove 16c, 17c, in each of the angled end 12a, 13a of a power supply wire 12, 13th threaded.
  • the areas normally hidden in the cross-section of FIG the contact lugs 16, 17 are shown in dashed lines in Figure 2.
  • the angle range the L-shaped contact lugs 16, 17 is sealed in the plastic base part 15 injected and therefore usually not visible.
  • the grooves 16c, 17c are respectively bounded laterally by two differently long webs 16d, 16e and 17d, 17e. Both webs 16d, 16e and 17d, 17e each have their groove 16c, 17c facing edge 16f, 17f, which is for threading the power supply wire 12, 13 serve in the groove 16c, 17c.
  • the shorter bridge 16e, 17e has a smaller width than the longer web 16d, 17d.
  • the welded connection between the power supply wires 12, 13 and the contact lugs 16, 17 is through Brief heating of the material of the shorter webs 16e, 17e over the Melting point produced by means of a laser.
  • the welded to the power supply wires 12, 13 L-legs 16b, 17b extend to that of the plastic base part 15 anchored support sleeve 14b formed interior.
  • the carrier sleeve 14b is provided at the height of the webs 16d, 16e, 17d, 17e with an opening 18, about the laser welding of the power supply wires 12, 13 with the short webs 16e, 17e of the corresponding contact lug 16, 17 after assembly the lamp base takes place.
