    lighting device
    The invention relates to a lighting device for single-lane motor vehicles, which is adapted to emit light in a first propagation direction, wherein the illumination device comprises an optical reflection device and a light module, wherein the optical reflection device is arranged in the beam path of the light and the light module emits light in a second propagation direction and the light emitted by the light module first falls on the optical reflecting device and is deflected by the latter in the first direction of propagation, wherein the at least one optical reflecting device comprises a reflecting surface, which is preferably flat, and about at least two pivot axes relative to a support frame is ver pivoted ,
    In single-track vehicles such as motorcycles occurs when cornering by tilting the vehicle, the problem that the usually rigidly connected to the motorcycle or the fork of the motorcycle headlights can no longer optimally illuminate the road ahead of the motorcycle.
    The term "carriageway" is used here for a simplified representation, because of course it depends on the local conditions, whether in the illumination of the roadway, a photo actually on the roadway or extends beyond Projection on a vertical surface in accordance with the relevant standards relating to automotive lighting technology.
    There are various approaches in the prior art to remedy this problem, for example, it should be noted that it can be provided to store the entire headlight in the motorcycle accordingly, so that it can be mitverschwenkt depending on the inclination of the motorcycle.
    This is disadvantageous in that the storage of the entire headlight in the motorcycle is complex and cumbersome and also has to be pivoted when cornering the entire headlight. As a result, a relatively large mass must be moved, the movement is slow and also requires a lot of space.
    Furthermore, headlamps according to the prior art often have rigid pivot axes, which means that these headlamps are indeed adjustable, but only about a fixed axis and within a fixed adjustment or rotation range.
    A fundamental improvement is known by a lighting device according to AT 500 893 Al. With the headlamp shown there, among other things, a regulation of the beam range is possible, and a cornering light function for single-track motor vehicles. Nevertheless, the arrangement in this lighting device is complex, since two separate, mechanical pivot axes are needed to form the required lighting functions of the headlight. The light source is rotatably mounted. Consequently, results from this headlight the disadvantage that the arrangement is difficult and sluggish in motion and also requires a lot of space, and a high number of components, which significantly increases the installation and maintenance.
    Underlying these problems, it is an object of the invention to provide a lighting device for a single-track motor vehicle, with which a cornering light can be realized, which can be easily and inexpensively hauled and mounted in the motor vehicle or maintain, and as few parts or Components must be movable.
    This object is achieved with a vehicle headlamp mentioned above in that according to the invention, the two pivot axes are located in or parallel to the reflection surface and intersect at a pivot point.
    Tilting the motor vehicle when cornering in the curve, only the reflection device, which reflects the light from the light module to the roadway, tilted about the two pivot axes, so that the light image on the road is adjusted accordingly.
    The inventive arrangement ensures that the reflection surface itself is pivotable about at least two axes. Consequently, the United pivoting device can be easier, easier and faster to move. This manifests itself in a simpler installation and maintenance of the headlamp, and can be found in a more agile, that is fast-reacting reaction behavior while driving.
    The construction of such a headlight is particularly simple if the reflection surface is flat. It can thereby be achieved that an electrical actuation of the adjusting devices of the reflection surface is particularly simple. But it is also possible to perform the reflection surface curved, for example, to keep the angular range of the pivoting small or to allow a particularly large angular range of pivoting or to achieve a particularly agile pivoting by a non-linear curvature of the reflection surface. In addition, the reflection surface can be curved to compensate for image distortions.
    It is advantageous if the optical reflection device comprises at least one ball joint whose fulcrum is located at the fulcrum, which rotatably connects the optical reflection device to the support frame around the fulcrum. As a result, an at least two-axis rotatable connection between the reflection device and the vehicle-mounted support frame is created.
    In a further development of the invention, the illumination device comprises at least two first actuating devices, which connect the optical reflection device with the support frame and are each arranged to effect a pivoting about a pivot axis. By the adjusting devices, a biaxial pivoting can be effected, which rotates the optical reflection device to the ball joint.
    In a further continuation of the invention, the at least two first adjusting devices are set up to carry out linear contractions or relaxations, each of which causes a pivoting about one pivot axis and which allows a particularly simple implementation.
    In a particularly advantageous further development of the invention, a second adjusting device is inserted between the ball joint and the supporting frame, which causes a linear movement transversely to the two pivot axes. By the second adjusting device can be effected that the optical reflection means is preferably moved in the direction transverse to the two pivot axes. It is favorable if the second setting device is set up to perform linear contractions or relaxations, which allows a particularly simple implementation.
    The ball joint forms the pivot point around which the optical reflection device can be rotated. The reflection surface, which deflects the incident light as a light beam from the second propagation direction in the direction of the first propagation direction, is not at the pivot point, which has the consequence that when pivoting the optical reflection means not only the reflection direction is changed, but for example, the position of Center of the light beam. To compensate for this undesirable effect, the position of the ball joint can be moved in the direction transverse to the two pivot axes.
    Further, by a displacement of the position of the ball joint in the direction transverse to the two pivot axes can be used to form a cornering light function. In general, it can be achieved that all axes of the illumination device according to the invention are freely adjustable and thus many degrees of freedom for purposes of adjustment, calibration, maintenance, test, for lighting functions and dynamic adjustment of light distribution in certain traffic and environmental situations are available. For example, the requirements on the generated light image in front of the vehicle may depend on the season or the rain intensity or visibility conditions, that is, in the case of fog, a high beam distribution may take on a different form than in clear visibility conditions. Furthermore, a dipped-beam light distribution in different load conditions, for example when driving on a single-track motorcycle, may require a multi-parameter adjustment of the cornering light which would only be very complicated to implement in the case of a headlight system based on rigid axles.
    Accordingly, the illumination means may comprise an actuator which connects the ball joint to the support frame and is adapted to perform linear contractions or relaxations and to effect a linear movement transverse to the two pivot axes. The linear movement may serve to correct a parallel shift of the generated light in the second propagation direction, thereby enabling a more accurate projection of the light image onto the roadway. This effect may cause optical changes in the photometry, possibly outside the tolerances in the light image, and in particular occurs at larger tilt angles of the optical reflection device. The illumination device may then have a larger tilt angle of the optical reflection device when the pivot point is at the edge of the optical reflection device, which is particularly advantageous for easy installation of the optical reflection device in a single-track motor vehicle, because the geometric distances of actuators far away may be arranged and consequently the accuracy requirements for the installation and the linear movements of the adjusting devices may be lower.
    It is particularly advantageous if the ball joint is arranged substantially in a region of the optical reflection device which is located in the imaginary extension of the first propagation direction. This may be approximately the midpoint of the diameter of the light beam, which dimension may well vary due to installation, to allow for flexibility to other aspects in the design of a vehicle headlamp. As a result, the aforementioned effect of the displacement of the light beam is particularly low and in some applications, no separate compensation of the displacement of the light beam is required.
    In a further variant of the invention, a gimbal in which an optical reflection device is rotatably mounted about two pivot axes, arranged in a vehicle headlight. A gimbal suspension allows pivoting of a component disposed in the center of the gimbal, such as an optical reflecting device according to the invention. The arrangement obtained is simple and easy to construct or produce. The gimbal may be implemented, for example, by an analog or digital micromirror in DLP © (Digital Micromirror Device) technology.
    It is particularly advantageous if the gimbal comprises a center of rotation as a pivot point, which is formed by the intersection of the two pivot axes and the pivot point is located in the imaginary extension of the first propagation direction. According to the invention, the optical reflection device can be arranged in the center of the gimbal, whereby the light in the headlight can be pivoted about two axes. This has the advantage that the two pivot axes and the reflection surface can be arranged in one point of intersection, and consequently no displacement of the light beam occurs as described previously.
    In addition, it may prove advantageous if the cardan suspension comprises two pivot bearings whose axes of rotation intersect and are arranged at right angles to each other.
    Furthermore, it is particularly advantageous if the two rotary bearings of the optical reflection device are set up to exert rotational movements in each case by a third adjusting device. The rotational movements can be exercised by linear contractions or relaxations of the third adjusting devices.
    Alternatively, the rotational motions may be effected by electrical or magnetic forces, as commonly used in mirror arrays in DLP® technology.
    It is advantageous if the gimbal comprises two intersecting, mutually perpendicular pivot bearing, wherein the two pivot bearings are each connected to an adjusting device and are each arranged to perform linear contractions or relaxations. By the adjusting devices, a biaxial pivoting can be caused, that the optical reflection device is rotated in the gimbal.
    When a pivot axis is substantially in a plane parallel to one
    Vehicle longitudinal center plane is or the vehicle longitudinal median plane is particularly easy to implement a cornering light function. This means that the position of the Ver-pivot axis but can also be arranged slightly different from it, for example, to consider installation instructions in the construction of a vehicle headlamp. Under the vehicle longitudinal median plane is to be understood by a plane through the vehicle longitudinal axis, which is a vertical plane when driving straight ahead of the vehicle.
    If a pivot axis lies substantially in a plane which runs transversely to the vehicle longitudinal center plane or the vehicle longitudinal center plane, a headlamp leveling of the headlamp can be realized in a particularly simple manner. Again, however, the position of the pivot axis may also be slightly different than previously described. For a particular low-cost installation of a headlamp according to the invention in a single-track motor vehicle, it is advantageous if the projection of the United pivot axis, is inclined α in the vehicle longitudinal center plane at an angle α to the vehicle longitudinal axis.
    It can prove to be particularly favorable when the illumination device is comprised by a motor vehicle headlight.
    In order to achieve a good illumination of the road ahead of the vehicle, it is provided that the projection of the United pivot axis is inclined in the vehicle longitudinal center plane at an angle to the vehicle longitudinal axis.
    The illumination is particularly good if this angle corresponds approximately to half the angle which the optical axis of the light module 502 encloses with the vehicle's longitudinal axis.
    A typical value for the angle between the optical axis of the light module and the vehicle longitudinal axis is 45 °. With this value, the angle is optimally chosen, since it requires little space in an optimal light image. For the angle between the Ver-pivot axis and the vehicle longitudinal axis thus typically results in a value of 22.5 °. Basically, however, deviations by approx. ± 10 ° (as far as the angle between the light module and the vehicle longitudinal axis is concerned) are fundamentally conceivable and sometimes also necessary depending on the structural conditions. Optically, even larger deviations may be possible.

    In the figures, important elements for the invention are shown, it being understood that further elements for installation in a vehicle headlight are necessary, which are not shown for clarity, however.
    Furthermore, lighting devices are shown in the figures, which are provided for installation in a vehicle headlight for single-track vehicles. Consequently, it is clear that in a built-in state of the illumination device, the emitted light is illuminated in the direction of travel of a vehicle in order to form a light image in front of the vehicle on the road. The term "road surface" is used here for the sake of simplicity, since, of course, it depends on the local conditions whether a photograph actually lies on the roadway or even extends beyond it. single-lane vehicle is located vertically and in the direction of travel.
    1 to 3 show a first exemplary embodiment of the invention of a lighting device 100 for single-lane motor vehicles, which is set up to emit light in a first propagation direction A, the illumination device 100 comprising an optical reflection device 101 and a light module 102.
    The illumination device 100 comprises an optical reflection device 101, which is arranged in the beam path of the light. The light module 102 emits light in a second propagation direction B and the light emitted by the light module 102 initially falls on the optical reflection device 101 and is deflected by the latter in the first propagation direction A.
    The at least one optical reflection device 101 comprises a reflection surface 103, which is preferably planar, and is pivotable about at least two pivot axes SA1, SA2 relative to a support frame 104.
    The two pivot axes SA1, SA2 are located in or parallel to the reflection surface 103 and intersect at a pivot point AP.
    In this embodiment, the posture of the pivot point AP is located at the center of the optical reflection device 101.
    The optical reflecting device 101 is connected to at least one ball joint 105 whose fulcrum is located at the fulcrum AP, which rotatably connects the optical reflecting device 101 to the supporting frame 104 around the fulcrum AP.
    Furthermore, the illumination device 100 may include two first actuators 106a, 106b, which connect the optical reflection device 101 to the support frame 104 and are respectively adapted to perform linear contractions or relaxations, each causing a pivot about each pivot axis SA1, SA2.
    It is clear that the two first adjusting devices 106a, 106b which connect the optical reflecting device 101 to the supporting frame 104 may also be suitable for outputting a current magnitude or the current position of the linear contractions or relaxations as a positional value by means of a sensor signal, for example, to perform control (not shown) of the mirror adjustments by feeding back the sensor signal to a control system (not shown).
    Alternatively, a control signal generated by a control system (not shown) may be used to drive the two first actuators 106a, 106b to form a control system (not shown).
    Consequently, the position of the optical reflection device 101 relative to the support frame 104 on the one hand by tapping a control signal or on the other hand by tapping a sensor signal to the two first actuators 106a, 106b done. It is also clear to the person skilled in the art that actuating devices or actuators in principle do not have any inherent sensor functions, but integration of a sensor in an actuating device is well known in the prior art. This can be done, for example, by optical sensors that can detect scales attached to elements of the actuator and convert into position data. Similarly, magnetic detectors can be used to detect a relative position or position change. Furthermore, mechanical means are suitable, for example, detect a longitudinal movement of the adjusting devices and perform a lever or gear device of a control or regulating mechanism. As a control or sensor signal can thus serve electrical signals, but also mechanical moments.
    The illumination device 100 may also include an actuator 106c connecting the ball joint 105 to the support frame 104 and configured to perform linear contractions or relaxations and to cause linear movement transverse to the two pivot axes SA1, SA2. This linear movement can serve to effect a correction of a parallel displacement A0 of the generated light in the second propagation direction B, thereby enabling a more accurate projection of the light image onto the roadway. This effect is shown in FIGS. 2 and 3 and occurs in particular at larger pivoting angles of the optical reflection device 101.
    By said arrangement of the pivot axes SA1, SA2, it is possible to pivot the optical reflecting device 101 about the pivot point AP, whereby a horizontal or vertical pivoting in the photograph in front of the vehicle may result. A vertical pivoting of the optical reflection device 101 can take place if both first actuators 106a, 106b are driven to the same extent, that is, perform either equal contractions or equal relaxation, as shown in FIG. As a result, a vertical angular adjustment of the optical reflection device 101 can be achieved together with the adjusting device 106c. In turn, if the first actuators 106a, 106b are driven in opposite directions or if both first actuators 106a, 106b are actuated to a different extent, for example if the first actuators 106a perform contractions and the other first actuators 106b perform relaxations, a horizontal angle adjustment of the optical reflection apparatus can 101 and thus a corresponding pivoting can be achieved (not shown in the figures).
    The ball joint 105 may be arranged substantially in a region of the optical reflection device 101, which is located in the imaginary extension of the first propagation direction A. The area can be arranged, for example, in the center of the light beam which is located in the first propagation direction A or, for example, by installation instructions when installed in a vehicle headlight also at another location which is nevertheless close to the center of the light beam.
    In addition, the illumination device 100 may include sensors for controlling the reflection optical device 101, which are not shown in the figures. These sensors are used to detect the position parameters of the vehicle, due to which the position adjustment of the reflection surface 103 can take place. Such sensors may be based on mechanical or optical principles, but may also be magnetic field, ultrasonic or radar sensors which generally detect the position relative to the road or a horizontal plane, the speed, acceleration or inertia and, for example, in MEMS technology ("microelectromechanical system"). , MEMS) are executed.
    FIGS. 4 to 6 show a second embodiment of the invention, wherein the position of the pivot point AP 'is located at the edge of the optical reflection device 201. Otherwise, the same applies as for FIGS. 1 to 3.
    Analogous to the above, in the lighting device 200, a second actuator 106c, 206c may be interposed between the ball joint 105, 205 and the support frame 104, 204, causing linear movement transverse to the two pivot axes SA1, SA2, SA1 ', SA2' , The linear movement may in turn serve to correct a parallel shift A0 'of the generated light in the second propagation direction B', thereby enabling a more accurate projection of the light image onto the roadway. This effect, which causes optical changes in the photometry, possibly outside the tolerances in the light image, is shown in FIGS. 5 and 6 and occurs in particular at larger pivoting angles of the optical reflection device 201. Compared with the first embodiment with the illumination device 100, the illumination device 200 has a larger tilting angle of the optical reflection device 201, which is due to the arrangement of the pivot point AP 'located at the edge of the optical reflection device 201. Consequently, the solution according to the invention is particularly suitable for being used in an arrangement after the illumination device 200.
    The second adjusting device 106c, 206c can also be used to enable or support a curve light function by a displacement of the ball joint in the direction transverse to the two pivot axes. In other words, a plurality of axes of the lighting device according to the invention can be set rotatable and linearly displaceable, whereby many degrees of freedom for adjusting light distributions in certain traffic and environmental situations are achieved, which can be responded to different traffic situations by the optical deflection of the generated light distribution by the Reflection surface 103, 203 can be dynamically adjusted.
    The ball joint 205 is arranged substantially in a region of the optical reflection device 201, which is located in the imaginary extension of the first propagation direction A '.
    The arrangement of the illumination device 200 moreover has the advantage of being able to be installed particularly favorably in a single-track motor vehicle, since the distances of the adjustment devices 206a, 206b, 206c are arranged farther apart and consequently the accuracy requirements for the installation as well as the accuracy of the linear movements the actuators 206a, 206b, 206c may be lower.
    Fig. 7 shows a third embodiment of the invention in which a cardanic suspension is used for the optical reflection means. The illumination device 300 emits light in the form of a light beam which is directed in a first propagation direction A "on the roadway area located in front of the motor vehicle.
    The illumination device 300 comprises a gimbal 307, in which the optical reflection device 301 is rotatably mounted about two pivot axes SA1 ", SA2". Furthermore, the gimbal 307 includes a center of rotation as a pivot point AP ', which is formed by the intersection of the two pivot axes SAl ", SA2". The pivot point AP "is located in the imaginary extension of the first propagation direction A".
    The illumination device 300 includes an optical reflection device 301 and a light module 302, wherein the optical reflection device 301 is arranged in the beam path of the light. The light module 302 emits light in a second propagation direction B "and the light emitted by the light module 302 first falls on the optical reflection device 301 and is deflected by the latter in the first propagation direction A".
    The optical reflection device 301 is pivotable about two pivot axes SA1 ", SA2" with respect to a support frame 304.
    The illumination device 300 may include an optical reflection device 301 with a preferably planar reflection surface 303, and a cardan suspension 307, in which the optical reflection device 301 is rotatably mounted about two pivot axes SA1 ", SA2".
    The gimbal 307 has a pivot point AP ", which is formed by the intersection of the two pivot axes SAl", SA2 "and the pivot point AP" may be located in the imaginary extension of the first propagation direction A ".
    The gimbal 307 may comprise two pivot bearings whose axes of rotation intersect and are arranged at right angles to each other. The optical reflection device 301 are each set up by the two pivot bearings, by a third actuator 306a, 306b, to exercise rotational movements. The rotational movements may be exercised by linear contractions or relaxations of the third actuators 306a, 306b.
    The two pivot axes SAl ", SA2" intersect in the reflection surface 403 or parallel to the reflection surface 403 at a pivot point AP ".
    The advantage of this embodiment is that both pivot axes SA1 ", SA2" lie in the same plane as the optical reflection device 301 and consequently no correction of a parallel shift of the generated light in the second propagation direction B "is necessary, which offers design and cost advantages.
    The gimbal may be formed, for example, by an analog or digital mirror / micromirror in DLP® (Digital Micromirror Device) technology, which has a very small overall size, and thus the gimbal 307 in Figure 7 is not to be considered to scale , For a micromirror in DLP®
    Technology, the mirror surface is very small, which may mean for the application described in a vehicle headlight that further optical elements, such as a projection optics is required. With a mirror in DLP® technology is often deflected by magnetic or electrical forces.
    The gimbal 307 may further include an adjustment axis 308, which is symbolically represented by a resulting travel in FIG. 7 and which permits linear displacement of the entire gimbal 307 to effect displacement of the emitted light image, for example, to enable a cornering function or support.
    FIGS. 8 to 10 show a lighting device according to the invention, which is comprised by a vehicle headlight for single-lane (power) vehicles.
    The illumination device 200 according to the invention consists of a light module 202, which in the embodiment shown is designed as a projection system. The light module 202 thus comprises in the embodiment shown a light source 210, a (main) reflector 211, a lens 212 and a diaphragm 213 for switching between the dipped and dipped headlights. The lens 212 is held with a lens holder 214 on the reflector 211 of the light module 202.
    The entire lighting device 200 is fixedly arranged in a housing, not shown. The housing itself is finished with a cover or a lens. The housing is installed in the motor vehicle in a corresponding opening.
    The light module 202 emits light in the form of a light beam, which is directed in a first propagation direction A '- the main emission of the illumination device - through the diffuser or cover not shown in the drawing on the front of the motor vehicle located lane area. When the vehicle is traveling straight ahead, the propagation direction A 'and the optical axis of the light module 502 lie in a vertical plane, as a rule in the vehicle longitudinal center plane 501, which passes through the vehicle longitudinal axis 500. When driving straight ahead, this vehicle longitudinal center plane 501 represents a vertical plane.
    In the beam path of the light between the scatter / cover plate and the light module 202, an optical reflection device 201 is arranged. In the embodiment shown, the reflecting device 201 consists of a plane mirror or reflector, i. a mirror / reflector having a planar reflective surface; but it can also be a mirror / reflector with e.g. curved surface or single or multiple kinked surface act.
    Light emitted from the light module 202 exits the light module 202 in a second propagation direction B ', is incident on the optical reflection device 201, and is redirected by the optical reflection device 201 in the direction of propagation of the light beam in the first propagation direction A'.
    The optical reflection device 201 is pivotable about at least one pivot axis SAR which lies substantially in a plane which runs parallel to the vehicle longitudinal center plane 501 or is the vehicle longitudinal center plane 501.
    Furthermore, the United pivot axis SAR on a direction component which extends substantially in the direction of the vehicle longitudinal axis 500. In principle, the pivoting axis can run parallel to the vehicle longitudinal axis 500, but a more optimal illumination is achieved if the projection of the pivot axis SAR in the vehicle longitudinal center plane is inclined at an angle α to the vehicle longitudinal axis 500. The angle α is approximately, but preferably exactly half the angle γ, where γ denotes the angle which occupies the optical axis 502 of the light module 202 with the vehicle longitudinal axis, ie α = γ / 2. A typical value is γ = 45 °, with larger deviations as mentioned above are possible.
    Consequently, a Ver pivot axis SAR 'is substantially in a plane which is parallel to the vehicle longitudinal center plane 501 or the vehicle longitudinal center plane 501 and a pivot axis SA2' substantially in a plane which is transverse to the vehicle longitudinal axis 500 or the vehicle longitudinal center plane 501.
    The arrangement of the pivot axis is such that the United pivot axis SAR in a rear, the light module 202 facing area Hegt deeper than in a light exit direction front area.
    As can also be seen from the figures, the pivot axis SAR extends close to the reflecting surface or directly through the surface of the reflection device. This is favorable, since then only little space is required for the pivoting movement of the reflection device 201.
    As already mentioned, it is advantageous if the reflecting surface of the reflecting device 201 is flat, since such is easy and inexpensive to manufacture, and further
    Swiveling axis SA1 'parallel to the surface of the reflection device 201 extends.
    Furthermore, the illumination device 200 has a further pivot axis SA2 'for pivoting the reflection device 201, wherein the pivot axis SA2' is substantially normal to the vehicle longitudinal center plane 501.
    In the non-limiting embodiment shown, the optical reflex device 201 is pivotable about an upper support frame portion 204 about the first axis SAT. For pivoting an adjusting device 206a, 206b, 206c - usually a motor - provided.
    FIGS. 11 to 13 each show a photograph when cornering with a motorcycle.
    In a non-pivoted light image 400, with the orientation of the center line 410 of the light distribution or the light image corresponding to the angle of inclination of the motorcycle, the curve itself is less well lit and, on the other hand, the light image (in this case on the right side next to the road, in a right turn on the other hand the oncoming traffic side) has a section in the light distribution that goes well beyond the horizontal H.
    If, on the other hand, the motorcycle rotates at an angle β when using a lighting device 200 according to the invention, the housing of the lighting device and the light module 202 and, in the case shown in FIG. 11, the support frame 204 also inclines by this angle β.
    However, according to the inclination β of the motorcycle, the reflection device 201 is now likewise pivoted, namely around the first pivot axis SAT, as shown in FIG. 12, so that the light distribution can optimally illuminate the curve.
    The pivoting takes place in the opposite direction to the inclination ß of the motor vehicle. The reflection device is usually pivoted about ß / 2 about the pivot axis SAT.
    The optical reflection device 201 is therefore typically not parallel to a horizontal plane when cornering.
    In order to prevent a possible lowering of the light image by this pivoting about the axis SAT, it is further provided that the reflection device 201 to the second
    Axis SA2 'is pivoted forward in the light exit direction, so that the light image is raised.
    A corresponding light image 401 is shown in FIG. 12. In this case, a cornering light function, in which the direction of illumination of the illumination device follows the road ahead of the vehicle, is not taken into account and the center line 411 is not optimally in relation to the course of the road.
    If the inclination ß decreases again by raising the motorcycle, then the reflection device is pivoted back both around SAR and SA2 '.
    The angle of inclination of the vehicle can be determined by various known techniques; z. B. via ultrasound or gyroscope. As a parameter for adjusting the reflection device, in addition to the angle β, for example, a speed and / or acceleration signal can also be included. Of course, it is also possible with the invention shown to adapt the photograph so that the brake nip is also compensated. The same is true even with strong acceleration, in which also an automatic headlamp leveling is possible.
    In this variant described can be realized with two adjusting devices for the Ver-pivoting movements about the two pivot axis three functions, namely a roll angle compensation, a cornering light and a headlamp leveling of the photo. In addition to the pivoting with respect to the inclination of the motorcycle, the light image 401 can be shifted in the direction of the horizontal axis H. As can be seen in FIG. 13, the light image 402 is shifted horizontally in the direction of the road, to achieve optimum illumination during cornering of the vehicle, which is indicated by the horizontal position of the center line 412 in FIG. 13 with respect to each of the center line 411 from FIG. 12 can be seen. This can be achieved in particular by causing a linear movement transversely to the two pivot axes. For this purpose, for example, the illumination device 200 according to the invention according to FIG. 4 or the illumination device 300 according to FIG. 7 is suitable.
    The rotation of the light distribution 401 shown in FIG. 12 in relation to the light distribution 400 of FIG. 11 can be achieved by a suitable combined pivoting about both pivot axes SAP, SA2 '.
