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 guide as from the EP 2 669 721 A1 are known, are often used in motor vehicle headlamp design, for example for the production of parking light distributions or daytime running light distribution, or for the generation of signaling functions, such as a flashing light function.
- the term “elongated” or “elongated” is to be understood that the longitudinal extension of the light guide (ie the extent in the light propagation direction in the light guide) is significantly greater, for example at least 5 times or at least 10 times greater than the transverse extent (in the transverse extension it is, for example, the or a diameter of the light guide).
- 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 delimiting the at least one light guide, and wherein the second end region of the light guide protrudes into the adhesive bed such that the translucent end surface contacted, at least in some areas, the adhesive present 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.
- an inner, the adhesive bed delimiting wall which is part of the housing or is formed by the at least one holder, at least one recess or opening through which the second end portion of the at least one light guide protrudes into the adhesive bed.
- the adhesive bed is, for example, a kind of U-shaped or V-shaped profile, with an outer leg, i. the outer wall of the adhesive bed and e.g. also the bottom of the adhesive bed is formed by the housing, i. Part of the housing is.
- 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.

- two optical bodies 16, e.g. so-called thick wall optics provided, in which the optical fibers 1, 2 feed the light emitted by them.
- this light propagates, preferably by means of total reflection, and exits at a front side of the respective optic body 16 and is radiated through the lens 12 into a region in front of the illumination unit 100, where there is a desired light distribution or a part of such a light distribution generated.
- 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.
- the lens can be completely clear, but can also have an optical structure for influencing the light passing through it.
- the illumination unit shown in the present example is provided for the realization of a daytime running light, which is typically intended to have a homogeneous as possible, characterized by its shape luminous impression.
- other lighting functions such as a direction indicator, brake light, tail light, position light, rear fog light, etc., can also be realized with a lighting unit according to the invention.
- FIG. 4 shows one of the two light guides 1 of the lighting unit 100, wherein further still a heat sink 17 is shown, on which the light source 3 is arranged.
- the optical waveguide 1 consists of an optically transparent material in which light coupled in via the coupling-in region 1a, in particular on the outer jacket of the optical waveguide element 1, is totally reflected and thus propagates along the longitudinal extent of the optical waveguide 1.
- the outer jacket of the light guide has on its front a light output surface 1 b and on its front side opposite the rear a Lichtumlenk schemes 1 c, so coupled from the light source 3 in the light guide 1 and in this propagating light at the Lichtumlenk occasions 1 c and the light outcoupling surface 1b is emitted from the light guide 1.
- the light redirecting surface 1c comprises - generally, i. is not limited to the embodiment shown - in a known manner, a plurality of prismatic, preferably juxtaposed elements, which incident on the Lichtumlenk Scheme 1c light, which propagates along the optical fiber 1 in this, deflect to the front, where it over the light output surface / Light exit surface 1b can escape as already described above.
- FIG. 5 and FIG. 6 show on the basis of the upper optical waveguide 1 that this - and preferably analogously thereto - the second optical waveguide 2 -in its second end region 21 has a translucent terminating surface 21a delimiting the optical waveguide 1, the second end region 21 of the optical waveguide 1 projecting into the adhesive bed 13, such that the end face 21a of the light guide 1 contacts the adhesive 14 located in the adhesive bed 13 at least in regions, preferably over the whole area.
