  • the invention relates to a motor vehicle lighting device which comprises at least one light source which emits light in the switched-on state, an optical device assigned to the at least one light source, into which light from the at least one light source is radiated, and an optical imaging system which is assigned to the optical device and which comprises the optical device images emerging light in front of the motor vehicle lighting device in the form of two light distributions, namely in the form of a main light distribution and a signlight partial light distribution.
  • the motor vehicle lighting device When the motor vehicle lighting device is installed in a motor vehicle and put into operation, the motor vehicle lighting device generates these light distributions at a distance in front of the motor vehicle.
  • the invention also relates to a motor vehicle with at least one such motor vehicle lighting device.
  • signlight partial light distribution is understood to mean a partial light distribution which serves to illuminate fastened traffic signs mounted high above a roadway.
  • the signlight partial light distribution is sometimes also called overhead sign partial light distribution.
  • a Signlight partial light distribution according to the ECE regulations can correspond to a partial light distribution which, depending on the type of light sources used and the control of the motor vehicle lighting device, in an upper half of Zone A (according to ECE R98) and / or Zone III (according to ECE R112) and / or in zone III (according to ECE R123).
  • the AT 514 784 A1 and AT 514 785 A1 describe an optical structure for a lighting device for a motor vehicle headlight, which can be applied, for example, to a lens surface for generating a signlight.
  • a disadvantage of this solution is that the optical structure strongly influences the properties of the lens and is also not preferred in terms of design.
  • the registration EP 2 799 761 A2 discloses a light module for a motor vehicle headlight, which has primary optics, which emits light from a light source into a Converts intermediate light distribution, wherein a horizontally arranged diaphragm is set up so that the light of the intermediate light distribution, which passes the diaphragm on a first side of the diaphragm, in a first beam path into one on a first side of the light-dark boundary in the second light distribution lying area.
  • the light module is characterized in that the primary optics are set up to deflect part of the light emanating from the light source in such a way that it passes the aperture on a second side of the diaphragm and from the secondary optics in a second beam path into one on one second side of the cut-off line is distributed in the area lying in the second light distribution.
  • the aperture is aligned horizontally. Therefore, the light module is, for example, unfavorable in terms of installation space.
  • DE 10316069 A1 a motor vehicle headlamp of the projection type, in which a diaphragm with an opening is provided.
  • the opening is designed and arranged such that light passing through the opening generates the Signlight.
  • the object of the present invention is to eliminate the above-mentioned disadvantages of the prior art and to provide a motor vehicle lighting device which takes modern design requirements into account, dispenses with costly and time-consuming optical structures and is space-saving.
  • the object is achieved according to the invention with a motor vehicle lighting device mentioned at the outset in that the optical device is set up to bundle the light from the at least one light source and to direct it to the optical imaging system in the form of at least two spatially separated light bundles - a first light bundle and a second light bundle , and the optical imaging system is configured to project each light beam in the form of a light distribution in front of the motor vehicle lighting device (the first light beam in the form of a main light distribution and the second light beam in the form of a signlight partial light distribution), the optical device at least one perpendicular to an optical one Is arranged downstream of the axis of the optical imaging system arranged aperture, wherein the aperture has at least a first opening and at least a second opening, wherein the at least one first opening
  • the lighting device comprises a plurality of light sources, preferably a plurality of LEDs
  • the optical device has a plurality of light-guiding optic bodies, with exactly one LED being assigned to each light-guiding optic body, each light-guiding optic body with respect to the associated LED in this way is arranged and / or designed such that only the light of the associated LED couples into the optic body.
  • One advantage is, for example, that the LEDs and the light-guiding optic body can achieve a collimated homogeneous light or a homogeneous light distribution with the desired outlet.
  • light-guiding optic body is understood to mean an optic body in which light rays coupled into the optic body propagate due to the total reflection and only leave it when they are on an impurity, such as a deflecting prism or contamination of the material, or strike an end of the optic body that includes an exit surface.
  • the term “light bundle” is to be understood as a spatially limited area in which light propagates. A light beam is limited by marginal rays. Therefore, in connection with the present invention, the term “two spatially separated light bundles” is understood to mean two non-overlapping, spaced light bundles, the edge rays of which do not overlap.
  • the first opening of the diaphragm has a lower edge, the lower edge forms a light-dark boundary in the light image, and the second opening is arranged below a central region of the first opening.
  • the term "vertical" refers to an axis of a coordinate system connected to the motor vehicle lighting device, which is oriented vertically when the motor vehicle lighting device is in a position corresponding to the installed state in a motor vehicle.
  • the coordinate system is selected such that it corresponds to a coordinate system in the image space that is used for measurements on the emitted light distributions.
  • the vertical in the coordinate system connected to the motor vehicle lighting device corresponds to the vertical on a measuring screen, which is set up in a lighting technology laboratory for measuring light distributions generated by the motor vehicle lighting device.
  • the optical imaging system can, for example, have a projection surface / projection plane, wherein all objects located in the projection surface are sharply imaged in an image space assigned to the optical imaging system.
  • the optical device has a continuous, preferably flat, light exit surface, on which light exit surface the diaphragm is arranged, preferably without a gap.
  • the advantage of this constellation is that a luminous image designed simultaneously through the light exit surface and the diaphragm or a luminous surface simultaneously designed through the light exit surface and the diaphragm can be arranged in the projection surface of the optical imaging system.
  • all light sources preferably all LEDs
  • all optical bodies starting from the Taper the light exit surface of the optical device
  • at least some of the light-guiding optic bodies, preferably all the light-guiding optic bodies have a common light exit plate.
  • the light exit plate is formed in one piece with the light-conducting optical bodies associated with the part, preferably with all light-conducting optical bodies.
  • the light sources are arranged in a horizontal row perpendicular to the optical axis of the motor vehicle lighting device and at least one optic body lying in the middle of the row has a preferably convex design projecting downward (with respect to the remaining optic bodies) , Has lower area, which extends from a light entry surface of the center in the row of optics body optic body to the light exit surface. It is advantageous here that a branching of the light from a single LED can be sufficient to generate the Signlight partial light distribution.
  • the lower region has a lower, preferably parabolic, boundary side.
  • the optical body lying in the center of the row is set up to form the second light beam.
  • the other light sources preferably LEDs, which are not used for the Signlight partial light distribution, can be dimmed as desired.
  • the main light distribution is designed as an apron light distribution with a straight horizontal cut-off line or as a low-beam light distribution with a cut-off line with an increase.
  • the optical imaging system is designed as a lens, the lens collimating the light beams in the vertical direction and expanding in the horizontal direction.
  • a light module 1 of a motor vehicle headlight is shown schematically, which can correspond to a motor vehicle lighting device according to the invention.
  • Figure 1 shows the light module 1 in a perspective view.
  • the light module comprises a light source 2, which is formed from a plurality of LEDs, for example arranged in a row, an optical attachment 3 located upstream of the light source, into which the light from the light source is coupled on the one hand and coupled out on the other hand, one perpendicular to an optical axis 4 of the light module 1 arranged aperture 5 and a lens 6, which can correspond to an optical imaging system according to the invention.
  • the front lens 3 can correspond to the optical device according to the invention and can be made of silicone, for example.
  • the front lens 3 has light-guiding properties, that is to say that the light coupled in from the LEDs on the one hand can propagate in this front lens 3 without significant losses until it emerges, ie on a light exit side 7 of the front lens 3.
  • a diaphragm 5 is provided which, depending on its shape and mode of operation, either at least partially blocks or transmits the light emerging from the light exit surface 7. It can be advantageous if the above-mentioned diaphragm 5 is arranged tightly / without spacing on the light exit surface 7 of the front lens 3.
  • the diaphragm 5 can, for example, be formed in one piece with the attachment optics 3 or on the latter using fastening means, for example screws, nails or adhesives be attached.
  • fastening means for example screws, nails or adhesives be attached.
  • An advantage here is that if the light module 1 is a low-beam light module, the diaphragm can form a light-dark boundary, among other things. It is also conceivable for the diaphragm to be formed separately from the light exit surface and to be spaced apart from it. In addition, it is conceivable that the diaphragm 5 can be displaceable using adjusting means (not shown).
  • the actuating means can be designed, for example, as an actuator which removes the diaphragm 5 from the beam path, as a result of which all the light emerging from the light exit surface 7 of the front lens 3 hits the lens 6. In this way it is possible, for example, to switch between a high beam and the low beam.
  • the light exit surface 7 of the front optical system 3 and / or the diaphragm 5 are / are preferably arranged in or spaced from a focal surface 8 of the lens 6 (for example a free-form lens), so that this lens 6 produces the light exit surface 7 generated by the diaphragm 5 in maps a given shape to the illuminated area in front of the light module 1.
  • a focal surface 8 of the lens 6 for example a free-form lens
  • the focal surface 8 is often also mentioned in connection with free-form lenses as a projection plane or intermediate image plane.
  • the projection plane is the illuminated area that is "thrown” / imaged into the image space through the imaging free-form lens or in connection with the vehicle construction - traffic space.
  • an image of the light source 2 for example light-emitting LED surfaces
  • the light module is installed in a motor vehicle, the light image is generated in front of the motor vehicle and can correspond to a preferably lawful light distribution.
  • Only the parts of the light module / motor vehicle lighting device are shown schematically, which can play a role in the embodiments shown.
  • an operational light module can also have other parts, such as, for example, heat sinks, support frames, mechanical and / or electrical actuating devices, covers and so on and immediately.
  • the description of these standard components of a motor vehicle lighting device / light module is omitted here.
  • FIG 3 a front view of the diaphragm 5 is shown, behind which a front lens 3 is arranged in front of the light source 2.
  • the light source 2 is one example horizontally aligned row of seven LEDs 2a to 2g arranged side by side.
  • the terms “horizontal” and “vertical”, “bottom” and “top” refer to the light module 1 installed in a motor vehicle.
  • the number of LEDs is of course irrelevant, and more or less than seven LEDs can also be used. It is also conceivable that the LEDs are not arranged in a row but in a matrix, for example.
  • the aperture 5 has two openings 9, 10. Because of these two openings, a luminous area is formed which is formed from two non-overlapping areas 11, 12.
  • a first light bundle emerges from a first region 11, which is formed with the aid of a first opening 9, and forms a main light distribution, for example an apron light distribution 31, in the light image.
  • a second light bundle emerges from a second region 12, which is formed with the aid of a second opening 10, which forms the Signlight partial light distribution 32 in the light image.
  • an apron light distribution 31 is understood to mean lighting the road below the horizon up to shortly (2-5 m) in front of the vehicle. It is a dimmed light distribution with a mostly straight horizontal light-dark boundary 33 (see e.g. Fig. 10 ). But it can also be a classic low beam distribution with an increase in asymmetry.
  • the shape of the light-dark boundary can be determined, for example, by a corresponding design of a lower edge 9 'of the first opening 9. With a straight horizontal lower edge 9 'of the first opening 9, a straight light-dark boundary can be created. If the lower edge 9 'of the first opening 9 has a kink / Z increase in the middle, the classic increase, that is to say the kink / Z increase, of a light-dark boundary is generated.
  • the in the Figure 3 Openings 9, 10 shown are rectangular. However, it is conceivable that the openings 9, 10 have a different shape from the shape of a rectangle. The corners of the openings 9, 10 or the openings 9, 10 themselves can be rounded, for example.
  • the first opening 9, as in Figure 3 is shown to have an elongated shape along the horizontal direction H.
  • This elongated shape of the first opening 9 expands the main light distribution generated and, for example, meets the legal requirements (for example, lighting in a range between -40 ° and + 40 ° horizontal extension) for an apron light distribution can be.
  • the second opening 10 can be expanded considerably less, so that its maximum extension is a fraction (for example a seventh) of the maximum extension of the first opening 9.
  • the second luminous region 12 of the light exit surface 7, which is restricted by the second opening 10 is used to form the Signlight partial light distribution set up.
  • the second opening 10 is spaced apart from the first opening 9, as in FIG Figures 1 and 3rd is shown.
  • the distance between the openings 9, 10 essentially depends on the legal requirements for the signlight partial light distribution and the optical parameters (for example the focal length) of the optical imaging system (for example the lens 6).
  • the second opening 10 can be arranged below and approximately in the middle of the elongated first opening 9. This is particularly favorable if the front lens 3 and the first opening 9 are designed symmetrically with respect to a V mentioned above projecting downwards. In general, it may be convenient if the second opening 10 is arranged symmetrically with respect to the vertical V.
  • a person skilled in the art adjusts the optically relevant components, for example the optical device, the optical imaging system and the diaphragm, accordingly. It is expedient, for example, to position the front optical system 3, the diaphragm 5 and the lens 6 in such a way that a coordinate system HOV assigned to the motor vehicle lighting device (see Fig. 3 ) corresponds to a coordinate system H'V 'on a measuring screen in a lighting laboratory, ie for example that the coordinate origin O of the coordinate system HOV corresponds to the HV point (see e.g. Fig. 10 ) corresponds.
  • the Signlight partial light distribution is symmetrical with respect to the vertical V 'on the measuring screen, as is the case, for example Fig. 10 can be seen.
  • the luminous areas 11, 12 can emit different luminous flux. Since the Signlight partial light distribution represents a substantially “weaker” illumination, it can even be advantageous if the second region 12 emits a lower luminous flux than the first region 11. At this point it should be noted that a Signlight partial light distribution measured at a distance of 25 m on a measuring screen may not exceed a value of 625 candela according to ECE R123.
  • Figure 4 shows a perspective view of a light source 2 'upstream lens 3'.
  • the light source 2 ' now has, for example, six LEDs 2a to 2f.
  • the front lens 3 ' has a continuous light exit surface 7' and in this respect the front lens 3 of FIG Figures 1 to 3 and the Figures 5 to 9 equal.
  • the attachment optics 3, 3 'shown have a different number of arms. The arms are designed as light-guiding optic bodies. However, it may be appropriate if this number corresponds to the number of LEDs, for example.
  • the arms 3a to 3g of the front lens 3 Figures 1 to 3 and the Figures 5 to 9 and the arms 3a to 3f of the front lens 3 'of Figure 4 emerge from a plate (light exit plate) 13, 13 'and end tapering in front of the light source 2, so that there is an air gap 14 between the arm ends 15 and the light source 2.
  • All arms 3a to 3c and 3e to 3f or 3g except for one arm 3d can be of the same design. However, it is conceivable that the arms 3a to 3c and 3e to 3f or 3g can be designed differently.
  • pairs of arms for example the arm 3c and the arm 3e or the arm 3b and the arm 3f, which are arranged on the side of the arm 3d and symmetrically with respect to the arm 3d, can each be of the same design. They have an upper concavely curved surface 16 and a lower substantially straight surface 17 and concavely curved side surfaces 18, 19.
  • these surfaces 16 to 19 can have different curvature profiles, for example they can be curved differently. There is an optical medium between the surfaces.
  • the course of the surfaces 16 to 19 delimiting the medium is adapted to the refractive index of the medium in such a way that light beams propagating within the arms 3a to 3g / 3f do not leave the arms due to the total reflection and essentially only through the light exit surface 7, 7 ' can emerge from the front optics 3, 3 '.
  • the arms 3a to 3g come together at a distance in front of the plate 13, so that light beams coming from different arms mix / overlap while they are moving in the direction of plate 13 and then in the further course in plate 13 in the direction of the light exit surface 7 spread.
  • the front lens 3, 3 ' has an arm 3d, which is designed differently than the rest of the arms. If the arms of the front lens are arranged in a row, the arm 3d preferably lies approximately in the middle of this row (see, for example Fig. 4 ). Again Figure 5 can be seen, the one arm 3d has a downwardly projecting, preferably convex lower region 20, which lower region 20 extends from a light entry surface 15 of the arm 3d to the light exit surface 7 and becomes ever higher in this direction.
  • the lower region 20 can be approx. 2 mm high and 2 mm long and have an intersection of approx. 20 mm.
  • the arm 3d is designed such that the light coupled into it from the LED 2d assigned to the arm 3d can be used at least partially to form the second light bundle.
  • the lower area 20 of the arm 3d runs out into a curved area 21 of the light exit surface 7, this curved area 21 projecting over an edge 23 of the light exit surface 7 ( Figures 4 to 7 and 9 ).
  • the second opening 10 of the diaphragm 4 is arranged and designed to match the curved region 21, as in FIG Figure 1 is shown.
  • light emerging through the arched region 21 of the light exit surface 7 is used to generate the Signlight partial light distribution, which light advantageously has a lower intensity than light coming from other arms, for example.
  • a lower boundary side 22 of the lower region 20 is designed as part of a paraboloid.
  • light rays that couple into arm 3d and pass through a focal point of the paraboloid are collimated. This increases, for example, the homogeneity of the Signlight partial light distribution.
  • Figure 10 shows an example of a light image generated with the motor vehicle lighting device according to the invention.
  • the light image comprises an apron light distribution 31 with a straight light-dark boundary 33 and a signlight partial light distribution 32.
  • the signlight partial light distribution 32 is spaced apart from the apron light distribution 31, ie it is a dark area 34 present in the vertical direction V between these two light distributions, as is the case with Fig. 10 can be seen.
  • This dark area 34 has the advantage, for example, that the light-dark boundary 33 is not blurred, but remains clearly visible.
