Definitions

  • the invention relates to a lighting device for a motor vehicle with a semiconductor light source for emitting light and at least one light guide arrangement for generating at least a portion of a dimmed light distribution.
  • Such a light guide arrangement is, for example, from the EP 0 766 037 A1 or from the EP 2 045 515 A1 known.
  • the from the EP 0 766 037 A1 known light guide arrangement comprises a flat, plate-shaped light guide, which serves to produce a low beam base light with a substantially horizontal light-dark boundary.
  • the known optical waveguide arrangement can only generate the low beam basic light if the plate-shaped optical waveguide is arranged vertically, and the external appearance of the switched-on optical waveguide arrangement (so-called night design) thus produces a vertical luminous line.
  • the known light guide arrangement can not produce a dimmed light distribution with a horizontal light-dark boundary. Rather, the light-dark boundary would always be perpendicular to the longitudinal extension of the exit surface of the light guide, in a horizontal or obliquely oriented light guide so vertical or oblique.
  • the present invention is therefore based on the object to design a light guide arrangement of the type mentioned in such a way and further that they can produce a dimmed light distribution, wherein the light-dark boundary is substantially parallel to a longitudinal extension of the light guide arrangement or a lens arrangement forming the light exit surface, so that with a horizontally oriented light guide arrangement, a substantially horizontal bright-dark boundary can be generated.
  • an optical waveguide arrangement with the features of claim 1 is proposed.
  • a dimmed light distribution with a light-dark boundary through an optical waveguide arrangement whose longitudinal extent runs essentially parallel to the course of the light-dark boundary.
  • a dimmed light distribution with a horizontal light-dark boundary can be generated by a horizontally oriented light guide arrangement.
  • the light guide arrangement On at least one side of the light guide, for example on an end face of the light guide, the light guide arrangement has a light coupling-in section with at least one light entry face. At least one light source of the illumination device is positioned in front of the least one light entry surface. A Main emission of the light source is preferably arranged perpendicular to the at least one light entrance surface.
  • the light guide has on its back Auskoppeliana, which are formed for example as decoupling prisms.
  • the rear side of the optical waveguide is the side of the optical waveguide which is directed counter to the exit direction of light from the optical waveguide arrangement.
  • a light exit surface of the light guide arrangement is arranged opposite the outcoupling elements on the front side of the light guide and has a lenticular cross section.
  • a first focal point of the lens section or the light exit surface lies on a lower edge of a Auskoppelements, and a second focal point of the lens section or the light exit surface is in the light exit direction at infinity or at a very large distance in front of the light exit surface.
  • the decoupling of the Auskoppelabites are preferably all arranged with their lower edges at the same height, ie on a common horizontal plane.
  • the first focal point is located anywhere on this horizontal plane, but in any case on the lower edge of the decoupling elements.
  • the focal points of several cross sections through the lens section are preferably on a focal line.
  • the extension of the focal line runs parallel to the longitudinal extension of the lens section.
  • the lower edges of the decoupling elements are preferably close to the focal line of the elongated lens-shaped light exit surface, so that the lower edges sharp at infinity (or at a great distance to the light guide arrangement) as a substantially horizontal Patoscuro limit resulting dimmed light distribution are sharply displayed.
  • the light sources of the illumination device are preferably designed as semiconductor light sources, in particular as light-emitting diodes (LEDs).
  • the Lichteinkoppelabêt between the at least one light source and the Lichtauskoppelabêt can be designed in a special way to influence the light distribution in the light guide assembly.
  • the light coupling-in section starting from the light coupling-in surface, can have conically diverging reflection surfaces in order to achieve collimating of the coupled-in light.
  • the collimated, substantially parallel light beams then preferably strike the outcoupling elements of the outcoupling section without further reflection at outer boundary surfaces of the light guide. It is likewise conceivable for the coupling-in section to be curved, that is to say to have curved reflection surfaces.
  • the decoupling elements of the Lichtauskoppelabitess are preferably designed as decoupling prisms having a longitudinal extent and in a section transverse to the longitudinal extent of a triangular shape.
  • the longitudinal extension of the decoupling prisms runs perpendicular to the main exit direction of the light from the light guide arrangement and perpendicular to the longitudinal extent of the lens section.
  • the decoupling prisms In their longitudinal extension, the decoupling prisms have a certain height h.
  • the height h of the prisms directly determines the vertical width of the resulting light distribution, in particular down into the apron a motor vehicle equipped with the lighting device according to the invention. Towards the top, the light distribution is limited by the essentially horizontal light-dark boundary. The larger the prism height h is selected, the greater the vertical width of the light distribution, that is, the more the apron is illuminated.
  • Different levels of decoupling prisms allow the light distribution to be influenced in terms of intensity and vertical width.
  • the lens section or the convex lens-shaped light exit surface may be configured in one piece with the light guide arrangement. But it is also conceivable that the lens-shaped light exit surface or the lens section and the remaining light guide arrangement comprising the at least one Lichteinkoppelabêt and the Lichtauskoppelabêt are formed as separate components. The convex lenticular light exit surface is then part of a separate, separate from the rest of the light guide arrangement designed lens portion. In particular, it is conceivable that the optical waveguide arrangement and the lens section are separated in a substantially vertical sectional plane which is perpendicular to a main light exit direction of the optical waveguide arrangement decoupled light and perpendicular to a horizontal cross section through the lens section.
  • the multi-part design of the light guide arrangement according to the invention has the advantage that the coupled into the light guide light can propagate only in the light guide, so that the volume in which the light can propagate, or the dimension in the cross section of the light guide in the light exit direction is reduced.
  • the coupled-in light is incident on a coupling-out element of the light coupling-out section with a higher probability and frequency and is coupled out of the optical waveguide.
  • the smaller the volume or the dimension of the optical waveguide in the light exit direction, in particular the depth of the optical waveguide in a main outcoupling direction of the light coupled out of the optical waveguide arrangement the more light is coupled out over the same length of the optical waveguide arrangement.
  • the amount of light to be coupled out of the light guide arrangement can be adjusted to achieve a desired light distribution with a desired intensity profile.
  • the optical waveguide arrangement can be movably arranged in a headlamp or luminaire housing, so that the light-dark boundary can be adjusted for basic adjustment, adjustment and / or headlight range control.
  • a light distribution with a horizontal light-dark boundary can be converted into a desired or legal one default setting can be brought.
  • a light distribution with a horizontal light-dark boundary can be adjusted in the vertical direction to realize a headlamp leveling. Accordingly, during operation of the light guide arrangement, the light distribution with a horizontal light-dark boundary can be adjusted in the horizontal direction to realize a cornering light function.
  • the decoupling elements of the light outcoupling section of the optical waveguide arrangement have a different width, that is to say have a different extent in the longitudinal extension of the lens section.
  • the probability and frequency that light coupled into the optical waveguide arrangement strikes a wider outcoupling element is greater than the probability that the coupled-in light will encounter a narrower outcoupling element.
  • the width of the decoupling elements can be increased at this point. Accordingly, it is also conceivable to vary the distance between adjacent light outcoupling elements in order to set the decoupled light quantity while the width of the light output elements remains the same. In particularly close coupled outcoupling elements, a larger amount of light is coupled out, as when the light outcoupling elements are arranged at a greater distance from each other.
  • an air gap is preferably formed between the light guide and the lens section.
  • any optically active elements are arranged, which scatter the light passing through, in particular in the horizontal direction.
  • the depth (extension in light exit direction) of the light guide tapers, starting from the at least one light entry surface of the light coupling section along the longitudinal extension of the light guide, that is viewed in the light exit direction, the light guide cross section, starting from the light entry surface to an opposite end of the light guide from.
  • the light guide has a rectangular cross-sectional area transverse to its longitudinal extent.
  • the cross-sectional area of the rectangular light guide is preferably designed to be just as high as the outcoupling elements.
  • the coupling-out elements extend over the entire height of the rear side of the light guide opposite the light passage surface of the light guide.
  • the lens section arranged at a distance from the light passage surface of the light guide preferably has a greater height than the light guide with the substantially rectangular cross-sectional area.
  • the lens portion Due to the smaller dimensions of the light guide, in particular by its lower height, relative to the lens portion results in a smaller cross-sectional area and thus a smaller volume of the light guide, so that in the light guide transported light over a given length more often hits a Lichtauskoppelelement and thus more light per Length emerges from the light guide and is represented by the lens portion as a dimmed light distribution with a substantially horizontal light-dark boundary on the road ahead of the motor vehicle.
  • the front in the light exit direction of the light passage surface of the light guide is preferably located with its lower edge at the height of the lower edges of the decoupling elements.
  • the focal line of the lens section with the first focal points preferably lies on or in the vicinity of the lower edge of the light passage surface of the light guide. Due to the separate configuration of the light guide and the lens section, the lens section can be configured as desired without affecting the light in the light guide, in particular its transport in the light guide and its coupling out of the light guide.
  • the cross-sectional area of the optical waveguide can be made smaller than that of the lens section to improve the coupling-out efficiency.
  • the light guide configured separately from the lens section can be designed as a rod-shaped light guide with a constant cross-sectional area along its longitudinal extent or with a cross-sectional area decreasing over the longitudinal extent starting from the light entry area. It is also conceivable that instead of a rod-shaped Optical fiber, a sickle-shaped light guide is used, as for example from the DE 10 2011 018 508 is known. In such a crescent-shaped light guide, light from at least one light source is collimated or parallelized by a collimator element after entering the crescent-shaped, plate-shaped light guide.
  • the entire collimated light impinges on a light output surface of the crescent-shaped light guide, through which the entire light is deflected in the direction of a light exit surface of the light guide.
  • the deflected light strikes the light passage surface of the crescent-shaped light guide so steeply that it is coupled out of the light guide and is imaged by the lens section arranged in front of the light exit surface to produce the desired dimmed light distribution with a horizontal light-dark boundary on the road ahead of the motor vehicle.
  • a focal line of the lens section arranged in front of the crescent-shaped light guide runs along the lower edge of the light exit surface of the light guide in the light exit direction and another focal line of the lens section at infinity or at a very large distance from the light exit surface of the lens section.
  • the light guide may be straight, but also curved.
  • the optical waveguide is curved in a horizontal plane which includes the focal line of the lens section with the first focal points, such that the light outcoupling surface of the optical waveguide rearward in the light exit direction has a smaller longitudinal extent than the front light transmittable surface of the optical waveguide.
  • the lens section can accordingly be designed curved. It is conceivable that the curvature of the lens section is chosen so that over the entire longitudinal extent of the light guide arrangement results in a substantially constant distance between the light guide or its light exit surface and the lens portion.
  • the distance between the curved optical waveguide and the curved lens section could vary over the longitudinal extent, preferably to increase continuously or to decrease continuously, starting from the light entry surface of the optical waveguide.
  • the focal length with the first focal points of the light exit surface or of the lens section across the different lens cross sections could then vary, so that despite the varying distance the focal line is always on the front side the decoupling or on the front light passage surface of the light guide is located.
  • the variation of the first focal length is conceivable both in the case of curved optical waveguide arrangements and in the case of straight light waveguide arrangements, as long as the first focal line is at height the lower edge of the decoupling elements extends. Even when using a crescent-shaped optical fiber, as described above, it is conceivable that the distance between the light exit surface of the crescent-shaped optical fiber and the lens portion varies.
  • each of the operated optical fiber assemblies can generate a part of a dimmed light distribution.
  • a first, for example, horizontally oriented light guide arrangement generates a low beam basic light with a horizontal light-dark boundary, which runs on a spaced at a distance to the motor vehicle measuring screen substantially parallel to and just below a horizontal.
  • a further light guide arrangement which is arranged obliquely to the first light guide arrangement, preferably at a 15 ° angle to this, could be arranged next to the first light guide arrangement.
  • the further optical waveguide arrangement could produce a dimmed light distribution with a light-dark boundary rising obliquely starting from the horizontal light-dark boundary, which preferably increases at a 15 ° angle.
  • the further light guide arrangement could be designed to generate a low beam spot.
  • the low beam spotlight could produce the rising part of a low beam distribution on the own road side according to the ECE regulation.
  • the two light distributions together thus produce a conventional, corresponding to ECE regulations asymmetric low beam with a first horizontal section on the opposite side (from the first Light guide arrangement) and a second, rising portion on the own traffic side (of the further light guide arrangement).
