Definitions

  • the invention relates to an electric lamp for a vehicle headlight according to the preamble of claim 1.
  • Such an electric lamp is for example in the international patent applications WO 97/25733 FR-A-2 557 357 and FR-A-2 557 358.
  • 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 Pinch of the lamp bulb is fixed in a metallic holder part, which in turn directly or via an intermediate ring with a metallic, annular Carrier sleeve is connected.
  • the metallic carrier sleeve is in the electric Terminals of the lamp equipped plastic base part of the lamp socket anchored.
  • the vehicle headlamp according to the invention has a lamp base, a translucent lamp envelope and at least one of the lamp envelope enclosed light source, the lamp base with the electrical connections the lamp provided plastic base part and at least one in the Plastic base part anchored metallic holder part for the lamp envelope.
  • the lamp envelope facing surfaces of the Plastic base part provided with a light-reflecting coating, which is designed as a sheet, which essentially the same light reflectance as the reflection surface of the Vehicle headlight reflector has.
  • the Light-reflecting sheet reduces the light absorption of the plastic base part and thereby reduces its thermal load and thus improves the Evaporation behavior of the plastic base part.
  • the light-reflecting increases Coating the efficiency of the headlamp, as that on the plastic surfaces incident light now by their light-reflecting coating for the headlight reflector is made usable.
  • the light-reflecting coating is aluminum sheet executed, which the lamp bulb facing Plastic surfaces of the lamp cap covers and the lamp bulb facing side is polished.
  • 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, consisting of molybdenum wire power supply lines 12, 13 is connected.
  • the pinch 10 a of the lamp bulb 10 is in a metallic holder, the from the cup-like holder part 14a, the intermediate 14e and the annular Carrier sleeve 14b is fixed.
  • FIG. 1 is the structure of the lamp according to the preferred embodiment and its use shown schematically in a headlight.
  • the lamp bulb 10 facing Top of the annular flange 15a is provided with a light reflecting, Sheet metal occupied ( Figure 2), which is essentially the same Light reflectance and the same color as the reflector 20 has.
  • the sheet may be an aluminum sheet whose the lamp bulb facing surface is polished.
  • an aluminum sheet can also be a metal sheet of another metal at the top of the annular Flange 15a be attached, if this is a similar high reflectance as the reflection surface of the headlamp reflector has.
  • the reflective sheet 21 may also be a steel sheet be, which is the lamp bulb facing the top of the annular flange 15a covers.
