  • the invention relates to a lighting device for a motor vehicle headlight for generating a light distribution with a cut-off line, the lighting device having at least one light source, a translucent body, one or more light feed elements for feeding light which emits the at least one light source, and a projection device , wherein the translucent body has a diaphragm device with a diaphragm edge region, the diaphragm device being arranged in the direction of light propagation between the light feed element and the projection device, and wherein light from the at least one light source enters the light-transmissive body via the light feed element, which first occurs in the translucent body Propagates light beam, and wherein from the aperture device, the first light beam is modified to a modified, second light beam that this z wide light bundle is imaged by the projection device as a light distribution with a light-dark boundary, the light-dark boundary, in particular the shape and position of the light-dark boundary, being determined by a diaphragm edge region of the diaphragm
  • An above-described lighting device for a motor vehicle headlight or motor vehicle headlight with one or more such lighting devices is known from the prior art and is used, for example, to implement a low-beam light distribution or part of a low-beam light distribution, in particular the apron light distribution of a low-beam light distribution.
  • a partial light bundle of the first light bundle strikes one of the boundary surfaces, the incident boundary surface, and at least a part of the partial light bundle completely or over a region of the incident boundary surface partially, as an exit light bundle, exits the translucent body, and wherein the exit light bundle re-enters the light-guiding body completely or partially via one of the boundary surfaces, the re-entry boundary surface, and wherein the entrance light bundle or parts of the Entry light bundle is projected by the projection optics device as a signlight light bundle into an area of the light distribution lying above the light-dark boundary, and, for example as a signlight light distribution, is imaged in the light image.
  • This emerging light which in particular is not absorbed, can penetrate the body again on the other side of the radiation diaphragm and thus reaches an exit surface of the projection device and is imaged above the HD line.
  • the Signlight is advantageously generated with a single component, no further components or additional lighting devices are necessary.
  • light rays that do not go into the light image i.e. those rays that do not re-enter the light-guiding body are preferably absorbed so that stray light can be suppressed.

  • the re-entry boundary surface has either a convex or a concave curvature in all horizontal cuts (except for those sections where it merges into a straight line, e.g. in the area of the diaphragm edge).
  • the curvature is concave in some areas and convex in others. In this way, an optimal adaptation of the light distribution, which is generated by means of those light rays which re-enter the light-guiding body via the re-entry boundary surface, can take place.
  • a concave design offers the advantage that the width of the Signlight distribution is increased due to the diverging lens effect.
  • a convex configuration offers the advantage that the width of the Signlight distribution can be increased without total reflections occurring on the lateral boundary surfaces of the light guide body. As a result, particularly narrow optic bodies can be used (low horizontal expansion).
  • intersection curves which are obtained by cutting the re-entry boundary surface with horizontal planes, e.g. run parallel to the optical axis of the projection device, each have an apex.
  • the vertices are those points on the intersection curve which have a maximum normal distance to a straight line which connects the two outermost points of the respective intersection curve.

  • the light-guiding body is preferably a solid body, as will be discussed in more detail in the description of the figures.

  • the different sections can be connected to one another by an inclined section. In this way, an asymmetrical light-dark boundary can be created.

Figure 8 shows three superimposed cuts at different heights, projected into a common plane, a cut being made in the area of the aperture edge 104, where the corresponding cutting curve (exceptionally) is straight as a result of the straight aperture edge 104 (in the example shown).
  • intersection curves 106b1, 106b2 each run symmetrically to the optical axis X, so that each intersection curve 106b1, 106b2 has an apex Pb1, Pb2 which, when the intersection curve is projected into a horizontal plane which contains the optical axis X, on the optical axis X lies.
  • Figure 8 shows the course of the light rays S4 after the re-entry of the light over the surface 106 into the optical body.
  • the rays S4 converge and then divergent.
  • the tuning is preferably carried out in such a way that the rays S4 essentially intersect at one point outside the optic body 110, that is to say in particular after the exit surface of the projection device 200, before they then divergently diverge.
  • a corresponding adjustment can be made via the radii of curvature of curves 106b2, 106b1; Due to suitable large radii of curvature, the intersection that arises moves in the light exit direction in front of the optics body. If the intersection is in front of the optic body, the width of the optic body can also be chosen to be smaller without the rays S4 being totally reflected on the lateral side surfaces.
  • surface 105 In conventional optics, it is often necessary to use surface 105, e.g. outside of surface 105 to provide a light absorbing body.
  • surface 105 when suitably designed, e.g. in which the entire area 105 is configured as a light exit area 105 ', or that area of the area 105 from which disruptive light rays emerge is designed as an area 105' through which light can specifically exit in the frame according to the invention, onto an absorbent additional component to be dispensed with.
