    Automotive illuminating device
    The invention relates to a motor vehicle lighting device comprising at least one light source which emits light when switched on, an optical device assigned to the at least one light source, into which light of the at least one light source is irradiated, and an optical imaging system associated with the optical device, which comprises the optical device Exiting 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 maps.
    Moreover, the invention relates to a motor vehicle with at least one such motor vehicle lighting device.
    In the context of the present invention, the term signlight sub-light distribution is understood to mean a sub-light distribution which serves for illuminating road signs mounted high above a roadway. The Signlight sub-light distribution is sometimes called overhead sign sub-light distribution. For example, a Signlight sub-light distribution according to the ECE regulations may 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).
    Automotive lighting devices for generating Signlight partial light distribution - in short Signlight - are known in the prior art. Applicants' 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 signal. A disadvantage of this solution is that the optical structure greatly influences the properties of the lens and also does not favor the design.
    The application EP 2 799 761 A2 discloses a light module for a motor vehicle headlight, which has a primary optic which emits the light emanating from a light source
    Transposed intermediate light distribution, wherein a horizontally arranged aperture is arranged so that the light of the intermediate light distribution, which passes on a first side of the aperture at the aperture in a first beam path in one on a first side of the cut-off in the second light distribution lying area. The light module is characterized in that the primary optics is adapted to divert a part of the light emanating from the light source so that it passes on a second side of the diaphragm at the aperture and from the secondary optics in a second beam path in one on a second side of the cut-off line is distributed in the second light distribution area. A disadvantage is that the aperture is aligned horizontally. Therefore, such an aligned aperture should be avoided for reasons of space.
    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 that accommodates modern design requirements, dispenses with costly and time-consuming optical structures and saves space. The object is achieved with an aforementioned motor vehicle lighting device according to the invention in that the optical device is adapted to focus the light of the at least one light source and to direct in the form of at least two spatially separated light beam to the optical imaging system, and the optical imaging system is adapted to the light bundles in the form of two light distributions in front of the
    Motor vehicle lighting device to project, namely in the form of a main light distribution and a Signlight sub-light distribution, wherein the optical device is arranged at least one arranged perpendicular to an optical axis of the optical imaging system aperture, wherein the aperture has at least a first opening and at least one second opening, wherein the at least one first opening is arranged to form a first light bundle forming the main light distribution, and the at least one second opening is arranged to form a second light bundle forming the signlight sub-light distribution.
    As is known from the prior art, the term "light bundle" is to be understood as meaning a spatially limited area in which light propagates, and a light bundle is limited by marginal rays
    Invention by the term "two spatially separated light bundles" two non-overlapping, spaced light bundles understood.
    With regard to a spatial separation of the light bundles, it may be advantageous if the first opening of the diaphragm has a lower edge, which lower edge forms a light-dark boundary in the light image, and the second opening below a central region of the first opening.
    With regard to proper positioning of the Signlight sub-light distribution in the light image, it may be expedient if the second opening is arranged below the first opening and symmetrically with respect to a vertical.
    With regard to the quality of the generated light distribution, it may be advantageous if the diaphragm is arranged in a focal plane of the optical imaging system. In this case, the term "focal plane" is not intended to be restrictive.The optical imaging system can have, for example, a projection surface / projection plane, with all objects located in the projection surface being sharply imaged in an image space assigned to the optical imaging system.
    It can be expedient for the optical device to have a continuous, preferably flat, light exit surface on which light exit surface the aperture is arranged, preferably without spacing. The advantage of this constellation is that a luminous image designed simultaneously by the light exit surface and the diaphragm or a luminous surface designed simultaneously by the light exit surface and the diaphragm can be arranged in the projection surface of the optical imaging system.
    In a practical embodiment, it can be provided that the motor vehicle lighting device comprises a plurality of light sources, preferably a plurality of LEDs, and the optical device has a plurality of light-guiding optical bodies, wherein each light-conducting optical body is associated with exactly one LED, each light-guiding optical body with respect to the associated LED is arranged and / or formed such that only the light of the associated LED couples into the optical body. An advantage here is, for example, that a collimated homogeneous light or a homogeneous light distribution with the desired outlet can be achieved by means of the LEDs and the light-conducting optic bodies.
    In order to keep the size of the motor vehicle lighting device small and to increase the size of the luminous area, it may be expedient if all the light sources, preferably all LEDs, in a plane perpendicular to the optical axis surface, preferably plane, and hold all optical body (starting from the Light exit surface of the optical device) in the direction of the light sources taper.
    In addition, it may be advantageous if at least a part of the light-guiding optical body, preferably all light-conducting optical body have a common light exit plate.
    In a particularly robust construction of the optical device, provision can be made for the light exit plate to be formed in one piece with the light-conducting optic bodies associated with the part, preferably with all light-conducting optic bodies.
    Furthermore, it may be advantageous if the light sources are arranged in a horizontal, perpendicular to the Lichthauptabstrahlrichtung series and at least one in the row centrally hibender optics body has a, preferably convex, lower portion which extends from a light entrance surface in the row the optic body extends in the middle of the optic body up to the light exit surface. It is advantageous that a diversion of the light of a single LED can be sufficient to generate the Signlight partial light distribution.
    In order to produce a particularly homogeneous, comfortable for drivers Signlight, it may be expedient if the lower portion has a lower, preferably parabolic trained boundary side.
    In order to make the Signlight partial light distribution wider, it can be advantageous if at least the optic body centrally in the row is set up to form the second light bundle.
    It can also be provided with advantage that only the centrally located in the row optics body is configured to form the second light beam. The other LEDs, which are not used for the Signlight sub-light distribution, can be dimmed at will.
    With regard to the use of the motor vehicle lighting device in city traffic, it may be expedient for the main light distribution to be in the form of an apron light distribution having a straight horizontal light-dark boundary or as a low-beam distribution having a rise-and-dark boundary.
    In order to facilitate compliance with the standards prescribed by law, it may be provided that the optical imaging system is formed as a lens, wherein the lens collimates the light beams in the vertical direction and expands in the horizontal direction.
    The invention is explained in more detail below with reference to exemplary non-limiting embodiments, which are illustrated in a drawing. In this shows:

    9 is a bottom view of Fig. 8, and
    10 shows an apron light distribution with a straight cut-off and a partial light distribution.
    First, reference is made to Figures 1 and 2. In these, a light module 1 of a motor vehicle headlight is shown schematically, which may correspond to a motor vehicle lighting device according to the invention. FIG. 1 shows the light module 1 in a perspective view. In this case, the light module comprises a light source 2, which is formed of several, for example arranged in a row LEDs, a light source upstream attachment optics 3, in which the light of the light source coupled on the one hand and coupled on the other hand, one perpendicular to an optical axis 4 of the light module 1 arranged aperture 5 and a lens 6, which may correspond to an optical imaging system according to the invention. The attachment optics 3 may correspond to the optical device according to the invention and may be formed, for example, from silicone. At the same time it may be useful if the optical attachment 3 has photoconductive properties, i. the on the one hand coupled light of the LEDs in this optical attachment 3 can propagate without substantial losses, until it on the other hand, i.e. emerges at a light exit side 7 of the attachment optics 3. In order to design a light distribution which is emitted by the operating light module 1, an aperture 5 is provided which either at least partially blocks or transmits the light emerging from the light exit surface 7, depending on its shape and mode of operation. It may be advantageous if the aforementioned aperture 5 is arranged tightly / without spacing on the light exit surface 7 of the attachment optics 3. Sealing / spacing means in this case that there is no air gap / distance between the light exit surface 7 of the attachment optics 3 and the diaphragm 5. The panel 5 may for example be integrally formed with the optical attachment 3 or attached to this by means of fastening means, such as screws, nails or adhesives. An advantage here is when the light module 1 is a low-beam light module and the diaphragm is provided inter alia to form a cut-off line. It is also conceivable that the diaphragm is formed separately from the light exit surface and spaced therefrom. In addition, it is conceivable that the diaphragm 5 can be displaceable by means of adjusting means (not shown). An advantage here is that a luminous surface produced at the light exit surface 7 can be changed rapidly in shape, e.g. while the light module is in operation in a motor vehicle headlight. The adjusting means may be formed, for example, as an actuator which removes the aperture 5 from the beam path, whereby the whole light emerging from the light exit surface 7 of the attachment optics 3 passes in the direction of 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 attachment optics 3 and / or the diaphragm 5 are / is preferably arranged in a focal surface 8 of the lens 6 (eg a free-form lens) or spaced therefrom so that this lens 6 generates the light exit surface 7 and by means of the aperture 5 in FIG a predetermined shape rendered luminous surface as a light image in front of the light module 1 images. It should be noted here that the focal surface 8 is also often called especially in connection with free-form lenses as a projection plane or intermediate image plane. The projection plane is that illuminated surface which is "thrown" / imaged by the imaging free-form lens into the image space or in connection with the motor vehicle traffic space. <br/> <br/> By means of the attachment optics 3, for example, an image of the light source 2, for example light-emitting LED surfaces It is understood that when the light module is installed in a motor vehicle, the light image is generated in front of the motor vehicle and corresponds to a preferably law-compliant light distribution Of course, an operational automotive lighting device also includes other parts, such as heat sinks, support frames, mechanical and / or electrical actuators, A, and the like covers and so on and immediately. For the sake of simplicity, however, the description of these standard components of a motor vehicle lighting device is omitted here.
    FIG. 3 shows a front view of the diaphragm 5, behind which a front optical system 3 located upstream of the light source 2 is arranged. The light source 2 is formed as an example, horizontally aligned row of seven LEDs arranged side by side 2a to 2g. The terms "horizontal" and "vertical", "bottom" and "top" refer to the light module 1 incorporated in a motor vehicle. Of course, the number of LEDs is irrelevant, and more or less than seven LEDs may be used. It is also conceivable that the LEDs are not in a row but e.g. are arranged in a matrix. The aperture 5 has two openings 9,10. Due to these two openings, a luminous area is formed, which is formed from two non-overlapping areas 11, 12. From a first region 11, which is formed by means of a first opening 9, a first light beam emerges which, in the light image, has a main light distribution, for example a light beam
    Apron light distribution 31, forms. From a second region 12, which is formed by means of a second opening 10, a second light beam emerges, which forms the Signlight partial light distribution 32 in the light image. In the context of the present invention, an apron light distribution is understood to mean an illumination of the road below the horizon to shortly (2-5 m) in front of the vehicle. It is a dimmed light distribution with mostly straight horizontal bright-dark boundary 33 (see, e.g., Fig. 10). But it can also be a classic low-beam distribution with an asymmetry increase. The shape of the cut-off line can be defined, for example, by a corresponding design of an upper edge 9 'of the first opening 9. With a straight horizontal lower edge 9 'of the first opening 9, one can create a straight cut-off line. If the lower edge 9 'of the first opening 9 has a kink / Z rise in the middle, then the classic increase, ie the kink / Z rise, of a light / dark boundary is produced. The openings 9, 10 shown in FIG. 3 are rectangular. However, it is conceivable that the openings 9, 10 have a different shape than a rectangle. The corners of the openings 9, 10 or the openings 9, 10 themselves may be rounded, for example. It is advantageous if the first opening 9, as shown in Figure 3, has an elongated along the horizontal direction H expanded shape. An advantage of this is that an elongation of the generated main light distribution is achieved by this elongated shape of the first opening 9 and thereby meets, for example, the legal requirements (eg lighting in a range between -40 ° and + 40 ° horizontal extent) to an apron light distribution can be. The second opening 10 may be significantly less expanded so that its maximum extent is a fraction (for example, one-seventh) of the maximum extent of the first opening 9. As already described, the second luminous area 12 of the light exit area 7, which is restricted by the second opening 10, is set up to form the Signlight partial light distribution. In order for the first light beam and the second light beam to be spatially separated, it may be expedient for the second opening 10 to be spaced from the first opening 9, as shown in FIGS. 1 and 3. The distance between the apertures 9, 10 depends essentially on the legal requirements for the Signlight sub-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 is disposed below and approximately at the center of the elongated first opening 9. This is particularly advantageous when the attachment optics 3 and the first opening 9 are designed symmetrically with respect to the vertical V. In general, it may be useful if the second opening 10 is arranged symmetrically with respect to the vertical V. It is understood that a person skilled in the art, the optically relevant components, such as the optical device, the optical imaging system and the aperture, adjusted accordingly. It is expedient, for example, for the front optics 3 to position the diaphragm 5 and the lens 6 in such a way that the coordinate system HOV (see FIG. 3) associated with the motor vehicle illumination device corresponds to the coordinate system on a measuring screen in a lighting laboratory, i. for example, the coordinate origin O of the coordinate system HOV corresponds to the HV point (see, for example, Fig. 10). As a result, for example, a correct positioning of the Signlight partial light distribution can be achieved without further effort. Preferably, the Signlight partial light distribution is symmetrical with respect to a vertical on the measuring screen, as can be seen for example in FIG. 10. The luminous areas 11, 12 can emit different luminous flux. Since the Signlight sub-light distribution represents a much "weaker" illumination, it may even be advantageous if the second area 12 emits a lower luminous flux than the first area 11. It should be noted that one in a 25 m Therefore, it may be advantageous that not all of the light source 2, but only a part of it, such as an LED 2d, illuminates the part of the screen, as measured on a screen, to illuminate the part second area 12. For this purpose, it may be expedient to provide a special attachment optics, which will be described in more detail below with reference to FIGS.
    Figure 4 shows a perspective view of a light source 2 'upstream attachment optics 3'. In this case, the light source 2 'now has, for example, six LEDs 2a to 2f. The attachment optics 3 'has a continuous light exit surface 7' and in this regard the attachment optics 3 of Figures 1 to 3 and Figures 5 to 9 the same. The shown attachment optics 3, 3 'have a different number of arms. The arms are designed as light-conducting optical body. However, it may be expedient if this number corresponds, for example, to the number of LEDs. The arms 3a to 3g of the attachment optics 3 of FIGS. 1 to 3 and FIGS. 5 to 9 and the arms 3a to 3f of the attachment optics 3 'of FIG. 4 emerge from a plate (light exit plate) 13, 13' and taper towards the end 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 made the same. However, it is conceivable that the arms 3a to 3c and 3e to 3f or 3g may be formed differently. In addition, arm pairs, e.g. the arm 3c and the arm 3e or the arm 3b and the arm 3f, which are arranged laterally of the arm 3d and symmetrically with respect to the arm 3d, may be formed the same. They have an upper concave curved surface 16 and a lower substantially straight surface 17 and also concavely curved side surfaces 18,19. These surfaces 16 to 19 may have different curvatures in the arms 3a to 3c and 3e to 3f or 3g, for example, be differently curved. Between the surfaces is an optical medium. In this case, the course of the medium-limiting surfaces 16 to 19 is adapted to the refractive index of the medium, that sprung beams propagating within the arms 3a to 3g / 3f do not leave the arms due to the total reflection and essentially only by the spruce exit surface 7, 7 '. from the attachment optics 3, 3 'can escape. As can be seen from FIGS. 8 and 9, which show a top view and a bottom view of the attachment optics 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 merge / overlap as they move in the direction Plate 13 and then in the further course in the plate 13 in the direction of the light exit surface 7 propagate. As a result, individual light emission surfaces of the LEDs are not imaged in the focal plane or projection plane 8 of the lens 6, but a homogeneously illuminating light exit surface 7 is achieved in which the individual LED images are not recognizable. An advantage of this is that the generated light distribution is also homogeneous.
    As mentioned above, the attachment optics 3, 3 'have an arm 3d, which is formed differently than the rest of the arms. In this case, if the arms of the attachment optics are arranged in a row, the arm 3d is preferably located approximately in the middle of this row (see, for example, Fig. 4). As can be seen from FIG. 5, the one arm 3d has a preferably convexly formed 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 is always higher in this direction. For example, the lower portion 20 may be about 2mm high and 2mm long and have a cutting width of about 20mm. In general, the arm 3d is designed such that the light coupled into it of the arm 3d associated with the arm 2d can at least partially be used to form the second light bundle. The lower region 20 of the arm 3d extends into a curved region 21 of the light exit surface 7, this curved region 21 projecting beyond an edge 23 of the light exit surface 7 (FIGS. 4 to 7 and 9). It may be advantageous if the second opening 10 of the diaphragm 4 is arranged and formed to match the curved region 21, as shown in FIG. In this case, light emerging from the curved area 21 of the light exit surface 7 is used to generate the partial light distribution, which light advantageously has a lower intensity than, for example, light coming from other arms. In addition, it may be expedient if a lower boundary side 22 of the lower region 20 is formed as a part of a paraboloid. In this case, light beams that couple into the arm 3d and pass through a focal point of the paraboloid are collimated, thereby increasing the homogeneity of the Signlight sub-light distribution.
    FIG. 10 shows an example of one with the invention
    Motor vehicle lighting device generated light image. In this case, the light image comprises an apron light distribution 31 with a straight cut-off line 33 and a partial light distribution 32. The partial light distribution 32 is spaced from the front light distribution 31, ie. There is a dark area 34 in the vertical direction V between these two light distributions, as shown in FIG. 10 can be seen. For example, this dark region 34 has the advantage that the light-dark boundary 33 is not blurred, but remains clearly visible.
    As long as it does not necessarily result from the description of one of the embodiments described above, it is assumed that these can be combined with each other as desired. Among other things, this means that the technical features of one embodiment can be combined with the technical features of another embodiment individually and independently as desired, in order to arrive in this way to a further embodiment of the same invention and without exceeding the original disclosure.
