Definitions

  • the invention relates to an above-mentioned lighting unit, which is designed as a motor vehicle headlight.
  • the invention also relates to a motor vehicle headlight, which has one or more lighting units mentioned above.
  • Elongated ladders are frequently used in motor vehicle headlamp design, for example for generating parking light distributions or daytime running light distribution, or for generating signaling functions, e.g. a flashing light function.
  • the term "elongate” or “elongated” is understood to mean that the longitudinal extent of the light guide (ie, the extent in the light propagation direction in the light guide) is significantly greater, e.g. at least 5 times or at least 10 times greater than the transverse extent (the transverse extent is, for example, the or a diameter of the optical fiber).
  • the optical fiber used has two open ends, at one end the light is coupled from one light source, while at the other open end there is no light injection.
  • Such elongate light guides typically terminate in typical illumination units for motor vehicle headlights in a region facing away from the coupling-in region a few millimeters after their visible portion, i. they only extend a few millimeters beyond the light output surface.
  • At the end surface, which terminates the light guide in this area facing away from the light source there is light reflections of the light coupled into the light guide and propagating as a result of total reflection by the light guide and thus to a significant increase in the light intensity in the end region of the light guide, resulting in typically one, sometimes several hotspots. This adversely affects the appearance of the light guide with the light source on for a viewer outside the motor vehicle, since the homogeneity of the appearance is disturbed by such a hotspot (or by several).
  • the light guide has a lower effective light exit surface and thus emits less light than the identical light guide, which is not covered by a diaphragm with the same power of the light source.
  • the at least one light guide in a second end region has a translucent end surface bounding the at least one light guide, and wherein the second end region of the light guide protrudes into the adhesive bed such that the end surface at least partially contacted the adhesive located in the adhesive bed.
  • a light guide within the scope of the invention thus preferably consists of an elongated body, which consists of a lateral surface which comprises the light outcoupling surface and the Lichtumlenk Structure, and a base surface which corresponds to the Lichteinkoppel requirements, and a top surface which corresponds to the end surface.
  • the lateral surface may be a cylinder jacket, base and top surface can just be trained.
  • both lateral surface and base and top surface can also be designed as desired, in particular, the cross-section of the lateral surface can be configured arbitrarily and be variable over the length of the light guide, deck and base must not be flat, and it does not have to each act around a single, continuous surface.
  • the adhesive is designed to absorb light, so that as much light as possible is absorbed in the adhesive and accordingly can not be reflected back into the optical fiber.
  • the adhesive is dark, especially colored black.
  • the end surface contacts the adhesive over the entire surface.
  • light can escape from the second end region of the light guide over the entire end surface and be absorbed in the adhesive.
  • At least one, preferably exactly one, holder for holding the at least one light guide is arranged in the housing.
  • the at least one holder forms the at least one holder together with the housing the adhesive bed for the cover plate, for example by the holder forms an inwardly bounding wall for the adhesive bed.
  • the entire adhesive bed is formed by the housing.

  • the inner wall that is, the inner leg of the U-shaped profile, may also be part of the housing, but we are often formed by the holder for the light guide (s), i. the inner wall is part of the holder.
  • the end surface in particular the geometry of the end surface, is chosen such that it has the highest possible transmittance, so that a good, in particular As large as possible light transmission through the end surface results.
  • the end surface may consist of a continuous surface.
  • the end surface consists of two or more individual surfaces.
  • the termination surface may impinge thereon at an angle below which total reflection does not return to the light conduit so that the light from the light conduit may exit into the adhesive bed where it is absorbed in the adhesive.
  • the angles at which the light impinges on the termination surface are at 90 ° or 90 °.
  • the hot spots disadvantageously formed in optical fibers are produced at the end of the optical fiber by light propagating substantially longitudinally through the optical fiber reflected from the end surface. This can be prevented or at least greatly reduced with a preferably described embodiment of the end surface.
  • the "central axis" of a light guide is an axis in the longitudinal extent of the light guide, which connects in each case the geometric centers of the cross-sectional areas along the longitudinal extension of the light guide, which are normal to this axis.
  • the above object is further achieved with a lighting unit described above, which is designed as a motor vehicle headlight.

  • the optic bodies can also be realized in a single component.
  • the light distribution generated by a light guide 1, 2 is rather wider scattered, the thick-walled optics collects the light by total reflection and thus forms on its front side, at which the light emerges, a sharply defined luminous surface.
  • optical body is present and the optical fibers emit light directly through the lens in an area in front of the lighting unit.
