Definitions

  • the invention is based on a lighting device, in particular headlights or headlight lamp unit, for motor vehicles according to the preamble of claim 1.
  • Such a lighting device is described in DE 44 42 682 A1 known.
  • This lighting device has one Light exit opening on that with a translucent Plastic disc is covered.
  • the disc is there colorless and has an appearance that is different from glass. Compared to the glazing the body of the motor vehicle results for the Lighting device thus a qualitatively less favorable appearance.
  • the lighting device according to the invention with the Features according to claim 1, in contrast, have the advantage that their appearance at least the other Glazing the body of the motor vehicle at least is similar and thus at least approximately equivalent.
  • FIG. 1 An embodiment of the invention is in the drawing shown and in the following description explained.
  • the figure shows a lighting device in a horizontal longitudinal section in simplified Presentation.
  • the Lighting device for Motor vehicles shown that have a headlight or a Headlight lamp unit is the one at the front end of the Body of the motor vehicle is arranged.
  • the Lighting device has a housing 10, the one Light exit opening 12 having a translucent disc 14 is covered.
  • the Cover plate 14 is attached to the housing 10.
  • At least one reflector 16 is arranged in the at least one light source 18 in the form of an incandescent lamp or a gas discharge lamp is used. Through the reflector 16 is light emitted by the light source 18 reflected, which exits through the cover plate 14.
  • the Housing 10 can have multiple reflectors and / or light sources be arranged for different light functions serve as low beam, high beam, fog light, and / or serve for signal functions, such as position lights or Flashing light serve.
  • the reflector 16 serves the reflector 16 with the light source 18 for generation a low beam and / or a high beam and / or a fog light beam.
  • another reflector 20 with a Light source 22 arranged, which form a flashing light, the light beam reflected by the reflector 20 through the cover plate 14 passes through.
  • the required Signal color for the flashing light can be changed by a correspondingly colored light source 22, by coloring the Reflection surface of the reflector, by a between which Reflector 20 and the cover plate 22 arranged Color filter or by appropriate coloring of the Part of the cover plate 14 through the reflector 20 reflected light passes through, can be achieved.
  • the cover plate 14 is made of plastic, preferably made of thermoplastic, for example PC (Polycarbonate) or PMMA (polymethyl methacrylate).
  • the Cover plate 14 is preferably in one Injection molding process manufactured.
  • the cover plate 14 can be at least substantially smooth, the means that no optical profiles are formed on it and at least the light reflected by the reflector 16 essentially unaffected by the cover plate 14 passes through.
  • the cover plate 14 can also have optical profiles at least in regions, by the light passing through is deflected and / or scattered becomes.
  • the cover plate 14 is not colorless, but such Tint has that the cover 14 a Appearance, the glass is at least similar.
  • the cover 14 can in particular be a green tint have that similar to the known thermal insulation glazing the body of motor vehicles.
  • the tint of the cover plate 14 can, for example, thereby be achieved that the plastic granulate from which the Cover plate 14 is made, is colored accordingly or that this at least a portion of colored Plastic granulate is added. When manufacturing on in this way you get a solid colored cover.
  • the tint of the cover plate 14 can alternatively also can be achieved with a suitably colored Coating 24 is provided.
  • the coating 24 can for example, be colored green and is preferably on applied to the outside of the cover plate 14.
  • the Cover plate 14 itself can be colorless in this case.
  • the coloring of the cover plate 14 or the coating 24 is such that its appearance when viewed from the outside is tinted accordingly, but the color of the light passing through the cover plate 14 is not or is changed only insignificantly and thus for that light emerging from the lighting device prescribed color location is not changed inadmissibly.
  • the light emerging from the lighting device for Low beam, high beam, fog light or side light is therefore still in the range of the prescribed white color locus and the one emerging for the flashing light Light continues to be within the prescribed range orange color locus.
