Definitions

  • the invention relates to a lighting device for a motor vehicle headlight for generating a light distribution according to the preamble of claim 1.
  • the invention relates to a motor vehicle headlight comprising at least one such lighting device.
  • 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 realize a low beam distribution or a part of a low beam distribution, in particular the front light distribution of a low beam distribution.
  • the EP 3 290 777 A1 such a lighting device.
  • Another lighting device is off JP 2017-084556 famous.
  • the light distribution of vehicle headlights has to meet a number of requirements.
  • minimum and maximum light levels are required in certain regions above the light-dark line (HD line) - i.e. outside the primarily illuminated area. These act as so-called “signlights” and enable overhead signposts to be illuminated, for example.
  • the light intensities used are usually in the range of the usual scattered light values, thus far below the light intensities below the HD line, but specified minimum light intensities must be exceeded. The required light values must be achieved with as little glare as possible.
  • the incidence boundary surface or a region of this incidence boundary surface is designed and/or arranged in such a way that light can exit from the light-transmitting body. This is done, for example, by an area of the incident boundary surface being inclined in relation to an optical axis of the projection device or the light-guiding body in such a way that incident light is not (totally) reflected or absorbed, but can exit the light-guiding body.
  • This exiting light which in particular is not absorbed, re-enters the body on the other side of the beam diaphragm and thus reaches an exit surface of the projection device and is imaged above the HD line.
  • the amount of light emitted and, to some extent, also the position in the light image can be controlled via the size of the area, which in extreme cases can also represent the entire incident boundary area, and the angle of incidence in order to meet legal signlight requirements.
  • the signlight is advantageously produced with a single component; no further components or additional lighting devices are necessary.
  • light rays which do not go into the light image i.e. those rays which do not re-enter the light-conducting body, are preferably absorbed so that scattered light can be suppressed.
  • the two boundary surfaces are designed as flat surfaces that run transversely to the optical axis.
  • the two surfaces are inclined at angles to the optical axis.
  • the area of the incident boundary surface that is provided for a targeted light exit is typically inclined somewhat differently than the rest of the incident boundary surface.
  • At least the area of the entry boundary surface is inclined in such a way, in particular to an optical axis of the projection device, that light exits completely or partially, as an exit light bundle, from the light-transmissive body and impinges on the re-entry boundary surface and the re-entry boundary surface is inclined in such a way, in particular to an optical axis of the projection device, that the exit light beam can re-enter the light-conducting body via one of the boundary surfaces, completely or partially as an entry light beam.
  • the re-entry boundary surface is inclined in such a way, in particular to an optical axis of the projection device, and/or the area and the re-entry boundary surface is inclined in such a way, in particular to an optical axis of the projection device , inclined and further inclined to each other at an angle such that incident light beam on its way through the light guiding body intersects the optical axis of the projection device before it is projected by the projection device in a region in front of the light guiding body.
  • the re-entry boundary surface has either a convex or a concave curvature in all horizontal sections (except for those sections where it merges into a straight line, e.g. in the area of the diaphragm edge).
  • a concave configuration 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-guiding body. As a result, particularly narrow optical bodies can be used (low horizontal expansion).
  • intersection curves that result from the intersection of the re-entry boundary surface with horizontal planes that run parallel to the optical axis of the projection device, for example, each have an apex.
  • vertices 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 to one another are referred to as vertices.
  • the vertices of the intersection curves lie on this optical axis when projecting into a horizontal plane which contains an optical axis of the projection optical device.
  • the progression of the intersection curves in a projection into the horizontal plane is symmetrical to the optical axis at the side of the vertex. It is also provided that as the normal distance between the horizontal planes and the optical axis increases, a) the curvature of the intersection curves increases, and b) the distance between the vertices lying in the horizontal planes and the aperture edge, measured in the direction of the optical axis in the light exit direction, increases will.
  • the incidence delimitation surface is designed and arranged in such a way that light rays impinging on the incidence delimitation surface, preferably all light rays impinging on the incidence delimitation surface, pass orthogonally through the incidence delimitation surface and/or the re-entry Boundary surface is designed and arranged in such a way that light beams of the exit light beam, preferably all light beams of the exit light beam, enter the light-guiding body orthogonally through the re-entry boundary surface.
  • the two boundary surfaces i.e. the resulting intersection lines of the boundary surfaces
  • undesired color effects are avoided.
  • the projection device is embodied as a projection lens arrangement or includes one, with the projection lens arrangement consisting of a projection lens, for example.
  • the light-guiding body and the projection device are designed in one piece.
  • the light feed element is formed in one piece with the light-conducting body.
  • the (or the) light input element (s), the light-conducting body and the projection device are formed in one piece with one another, in particular are formed from a single, light-conducting material and form a single body.
  • the light-guiding body is preferably a solid body, as will be explained in more detail in the description of the figures by way of example. It is particularly advantageous if the projection device and also the light feed element are an integral part of the light-guiding body, ie together form a single body (hereinafter also referred to as "optical body") or a single component.
  • the area into which the entry light bundle or parts thereof is or are projected extends in the light image in the vertical direction over a range of approx. 1°-6°, preferably over a range of 1.5 ° - 4.5° above the 0°-0° (HH) line, the horizon.
  • the area into which the incident light beam or parts thereof is or are projected extends horizontally in the light image over a range of approx. -24° - +24°, preferably from approx -18° - +18° extends.
  • the aperture edge is a single edge.
  • the edges can then be arranged one behind the other in the light exit direction.
  • the edge or edges can be as sharp as possible or, for example, rounded.
  • the diaphragm edge region can have the same normal distance to this horizontal plane everywhere transversely to the optical axis X in relation to a horizontal plane, for example a horizontal plane which contains the optical axis X.
  • different (vertical) Has normal distances to the plane For example, in a first section the diaphragm edge area can have a first normal distance to the plane and in a second section can have a second, larger normal distance.
  • the different sections can be connected to one another by an inclined section. In this way, an asymmetrical light-dark boundary can be created.
  • an asymmetry in the light-dark boundary can also be achieved in that the different areas of the diaphragm edge have different distances to a vertical plane normal to the optical axis in the horizontal direction, ie in the direction of light propagation or in the direction of the optical axis have axis.
  • the light feed element preferably comprises a light-shaping optics, which shapes the light emitted by the at least one light source in such a way that it is essentially radiated into the diaphragm edge region of the diaphragm device.
  • the above formulation which describes a bundling of the light beams onto a focal point or a focal plane of the projection device, which lies in or approximately in the diaphragm edge area, describes a simplified representation for a punctiform light source.
  • a punctiform light source e.g. LED chip, with an emission edge length of around 1 mm

  • the light feed element e.g. as part of the light shaping optics, comprises deflection means, e.g. one or more reflecting surfaces, preferably one or more surfaces, on which light is totally reflected, with which the light of the at least one light source in the desired direction is diverted.
  • the at least one light source can be arranged, for example, in the area of the optical axis of the optic body and have a main emission direction approximately in the direction of the optical axis.
  • the at least one light source can also be above or below the optical axis and light at an angle >0° to the optical axis Axis, for example at 90 ° to the optical axis radiate.
  • deflection means are advantageous.
  • the Lichtform optics are designed in such a way that light is not only collected at the focal point, but also in such a way that light is also aimed vertically higher, over the edge of the aperture. This allows the light distribution to taper off along the VV line from the HV point down to just in front of the vehicle.
  • the light-guiding bodies according to the invention form a front-end light distribution. Provision is preferably made for the diaphragm edge area to lie essentially in a focal line or in a focal surface of the projection device.

  • figure 8 shows the course of the light rays S4 after the re-entry of the light via the surface 106 into the optical body.
  • the beams S4 converge and then diverge.
  • the coordination is preferably carried out in such a way that the beams S4 outside of the optics body 110, ie in particular after the exit surface of the projection device 200, essentially intersect at one point before they then diverge divergently.
  • a corresponding adjustment can be made via the radii of curvature of the curves 106b2, 106b1; due to suitably large radii of curvature, the resulting point of intersection migrates in the direction of the light exit in front of the optic body. If the point of intersection is located in front of the optic body, the width of the optic body can also be selected to be smaller without the rays S4 being totally reflected at the lateral side surfaces.
  • FIG. 1 In the case of conventional optical bodies, it is often necessary to provide a light-absorbing body on the surface 105, for example outside the surface 105.
  • FIG. 1 In the present invention, with a suitable design, for example in which the entire surface 105 is designed as a light exit surface 105 ', or that area of the surface 105 from which interfering light beams exit, is designed as a region 105' through which light can exit in a targeted manner in the frame according to the invention, an additional absorbing component can be dispensed with.
