  • a desired Signal image of the headlamp unit as well as in relation to the external form of the headlamp unit per se, be around the area between the reflector and the lens array arranged means for coupling light in those those rays of light that are not on the first lens array be thrown into a fiber optic system with Couple light exit surfaces.
  • the light exit surfaces are in the direction of illumination of the vehicle headlight arranged and bundle the coupled-in part of the radiation in the illumination direction off the motor vehicle headlight out.
  • Main tasks of the Fiber optic system is an improved illumination of the area in front of the motor vehicle and thus a reinforcement of the Signal image and an accentuation of the light image with respect the luminance of the motor vehicle headlight.
  • From the Swiss Patent No. 184 110 is a Headlamp with multiple light sources, e.g. High beam and Dipped beam, and a device to indicate operation known light sources, which is influenced by these light sources can be and at least one of the light sources is shielded in relation to the display device in order to the display device to indicate whether a particular light source lit or not.
  • the known display device met mainly security and control functions.
  • a vehicle lamp with a housing and a seated in a lamp holder lamp which is disposed within the contour of a reflector, and a lens for covering the reflector and the housing, wherein the reflector from a hermetically through the Lens completed hollow body is made and an at least partially translucent indentation projects into the reflector hollow body.
  • the reflector hollow body and the feeder are made in one piece from transparent plastic, wherein the reflector hollow body is coated inside with an applied reflective layer.
  • the lamp is surrounded by an optic, which differs light deviating from the main beam direction in the direction of optical elements, which are arranged in the region of reflector housing sites where no reflective layer is applied and which are thus transparent.
  • the present invention is concerned with the problem of providing an improved embodiment for a motor vehicle headlamp of the type mentioned at the outset, which in particular allows to use a light emitted by the light source.
  • the invention is based on the general idea, in one Motor vehicle headlight, which has a light source and a the light source surrounding the reflector and a lens assembly has a light deflecting device or a prepared To provide a mounting point for the light deflection device, which emitted from the light source scattered light to a arranged at a substantially arbitrary position in the housing or attachable optical part passes.
  • the reflector focuses the light emitted by the light source in the essential in the direction of the lens assembly, whereas the Lichtumlenkvorraumettiating from the main beam direction Stray light to the described optical part passes and this example lights up.
  • an optical part in Form of a non-self-illuminator can be arranged, thereby the creative freedom regarding a differentiation possibility different types of headlamps, a brand-specific Differentiation, for example by an im Optical part integrated emblem, which diffuse incident Stray light is illuminated, as well as an individual night design be extended without requiring an additional Light source is needed.
  • the deflection device allows beyond that, that to be lit or to be lit.
  • Optical part in the direction of light of the motor vehicle headlight is arranged behind the reflector and thus far unreachable surfaces opens up in the headlight.
  • the light deflection device can be easily and individually adapt to the respective requirements or into the respective requirements Insert intended mounting location, without being larger Cost or increased installation costs arise.
  • the light deflection device as a reflector or is designed as a light-guiding device.
  • reflectors can be simple and inexpensive in almost any form, for example as mirrors or as coated elements, be manufactured and ensure an effective light redirection.
  • An education as a light-guiding device offers
  • the advantage that in the course of the light guide Branches may be provided which the coupled Light in different directions, for example forward to several optical parts and thereby the creative Additionally increase travel.
  • the light deflection as Form a prism which has the optical advantage, Color-differentiated light on the light exit side radiate.
  • a differentiated color Create night design which is an unmistakable Nocturnal signal image generated and thereby simply one certain headlight or vehicle type are assigned can and facilitates the recognition.
  • the Optics part have optical elements which refractive and / or are designed for deflecting the light.
  • the optical elements can beispw.
  • the optical part is an emblem which illuminates by the diffuse incident light becomes.
  • emblems come here, for example Lettering, logos, etc. into consideration, which in particular at nocturnal environment, the assignment of the product to a specific Make brand and / or company easier.
  • the optical part of heat-resistant and transparent Plastic in particular made of acrylic glass, formed be.
  • Acrylic glass optics offer the advantage that they are As Kunsstoffspritzgussteil in almost any shape cost can be made and easily adapted to specific Requirements are customizable. In addition, they have a low Density and thereby burden the total weight of the vehicle only marginal. Also injury consequences in a possible Accidents can be assessed much better with acrylic glass as with optical parts made of glass.
  • Fig. 1 shows a longitudinal section through the inventive Motor vehicle headlamps.
  • an inventive motor vehicle headlight 1 a lighting device 2, which a Light source 3, a light source 3 surrounding the reflector. 4 and a lens assembly 5, and wherein the reflector 4 the light emitted from the light source 3 substantially reflected as a parallel light beam in the direction of the lens assembly 5.
  • the lighting device 2 is arranged in a housing 6, which in the direction of illumination of the motor vehicle headlight 1 completed with a transparent headlight cover 7 is.
  • the reflector 4 can be up to the lens arrangement 5 are executed substantially closed or a have unspecified opening, which a Prepared mounting point 9 for a light deflection device 8 forms and in which the light deflection device 8 can be used is.
  • the light deflecting device 8 conducts light emitted from the light source 3 Stray light 13, 13 'to a at a substantially arbitrary position in the housing 6 arranged or attachable Optics 10 and 10 'continue.
