    HEADLIGHTS FOR VEHICLES, ESPECIALLY FOR ONE-SIDED MOTOR VEHICLES
    The invention relates to a headlamp for vehicles, in particular for single-lane motor vehicles, the headlamp comprising an apron light module, the apron light module radiating light to form a partial light distribution in a region in front of the apron light module, and a main light module Main light module comprises light for forming a modifiable fundamental light distribution of a certain type in a region in front of the main light module.
    Moreover, the invention relates to a vehicle with at least one such headlight.
    Modern vehicle headlights have a great functionality and are able to fulfill several lighting functions. A certain light function is fulfilled when the headlamp has a light distribution of a certain type, e.g. a Abblendlichtverteilung or a high beam distribution or other regulatory light distribution can radiate.
    In order to increase driving safety during evening and night driving, headlights with special functions are used in motor vehicles. As a headlight with a cornering light function (often cornering light mode, see, for example, Regulation No. 123 of the United Nations Economic Commission for Europe (UN / ECE), ECE - R123 for short), a headlight whose direction of lighting can be adapted to the road. Such an adaptation is particularly advantageous when driving on winding roads, especially as a result of this a better field of view is obtained when cornering.
    In single-track vehicles, another factor comes into play, namely the inclination of the motor vehicle when cornering. As is known, a one-lane vehicle, for example, turns a motorcycle into cornering cornering, which also causes the light image emitted by the headlamp to tilt, and it is desirable for a headlamp for single-lane motor vehicles with a cornering function to also have an inclined position An adaptation of the light image to the inclined position is called roll angle compensation
    Roll angle compensation system is advantageous for two reasons: Firstly, the road is better illuminated for the motorcyclist, on the other hand, the oncoming and leading road users are less dazzled. At the same time, the advantages of roll compensation systems come to the fore even at low inclinations.
    In the prior art known Rollwinkelausgleichsystemen, which can be found for example in BMW vehicles, the headlights consist of a very complex dynamic rotary mirror system and, for example, a xenon burner (HID lamp) as a light source. The rotary mirror system and a projection lens are controlled by stepper motors. The complex technical implementation of such mobile systems is disadvantageous and often unwanted by motor vehicle manufacturers, since a large installation space is needed for the implementation. However, this is often not the case especially with single-lane motor vehicles, which is why one must resort to lenses with low focal length and small diameter and thus the luminous flux on the road can only be achieved by a lower efficiency. In addition, the design is limited by the mirror. Inserting LEDs is also difficult because heavy heatsinks are required for multiple light emitting LEDs.
    The described disadvantages of the prior art should be eliminated. It is therefore an object of this invention to provide a headlight, realized with the cornering light function and especially roll angle compensation function and structural and stylistic requirements of customers can be accommodated.
    The measurement and analysis of a light image emitted by a headlight is done by a measuring screen arranged perpendicular to the optical axis of the headlight and illuminated by the headlight at a certain distance in front of the headlight. The illumination creates a light distribution on the screen. In order to specify the position of a point on the screen requires a coordinate system. With regard to headlamps, a special orthogonal pair of coordinates - x-axis and y-axis - is usually defined (XY coordinate system for short), with the x-axis at the statutory reduction of 0.57 ° in ECE space (0.40 ° in the USA) below the usual horizontal or hh-line (called ECE-R123 line HH). The hh-line or the horizon, together with a w-line orthogonal to it, forms a second horizon-related coordinate system with hh and w coordinates. The XY coordinate system is a headlight coordinate system, i. If the position changes, for example the inclination of the headlight with respect to the hh line, the position of the XY coordinate system also changes accordingly. The point position on the screen is given in degrees. The light intensity values are recorded in the form of a two-dimensional distribution and displayed, for example, as an isolux line diagram (isolux lines). The transitions from brightly lit to dimmed light distribution areas are called light-dark boundaries (HD boundaries).
    The aforementioned object is achieved with a headlamp mentioned above according to the invention that the main light module is assigned a control unit, which control unit is adapted to modify the modifiable basic light distribution to a modified basic light distribution, and the modifiable basic light distribution or the modified fundamental light distribution completes the partial light distribution to a total light distribution, the partial light distribution is substantially homogeneous and has a rectilinear upper apron HD boundary, the partial light distribution being to the x-axis (associated with the headlamp ) adjoins from below, wherein the basic light distribution only a maximum light intensity range, ie an area in which the light intensity values are greatest.
    The requirement of the homogeneity of the partial light distribution is the requirement of a substantially constant same luminance in the light image, ie. within the sub-light distribution, the same. This change can be quantified by gradient values, for example.
    A total light distribution emitted by the headlight according to the invention fulfills the requirement for homogeneity and the legal requirements.
    More generally, there is a desire for more functionalities for adaptive front lighting systems (AFS) with high resolution and short response times. However, the known devices are either very complex in their complexity or show dissolution problems in at least one, usually in the horizontal direction. This also applies to headlamps that use an LED matrix to illuminate, with optional segments of the matrix turned on or off. Here, the resolution is in favorable cases at 1.5 °.
    In order to realize the roll angle compensation function in accordance with the regulations and to adapt the overall light distribution to different traffic situations (eg to hide oncoming or preceding road users or pedestrians or other objects), it is advantageous if the control unit modifies the modifiable basic light distribution of a specific type Basic light distribution of the same type or of a different type, wherein the modified fundamental light distribution is shifted in parallel with respect to the modifiable fundamental light distribution along the hh-line.
    It can be provided that the main light module has at least one light source and at least one mirror element associated with the at least one light source, wherein the at least one light source emits light for irradiating the mirror element and the mirror element emits the incident light to form the modifiable fundamental light distribution diverts and / or reflects.
    In an expedient variant it can be provided that the basic light distribution is designed as a partial high-beam distribution.
    The fundamental light distribution formed as a partial high beam distribution can, for example, by "dimming", i.e., by lowering the light source luminosity, of its selected areas, complete the partial light distribution radiated by the apron light module into different total light distributions.
    In general, various total light distributions can be realized. In view of different traffic situations, it is advantageous if the control unit modifies the modifiable basic light distribution in such a way that the total light distribution is designed as a glare-free overall high-beam distribution with cornering light mode or a low-beam distribution with cornering mode or a city light distribution or a bad weather light distribution.
    The above-mentioned dipped-beam light distributions are light distributions which are produced as low-beam or dipped-beam headlights of class C, E, V and W according to ECE-R123 or as a superposition of dimming lights of these classes.
    In order to achieve a high resolution of the light image, it can be provided that the main light module has at least one light source, at least one optical unit associated with the at least one light source, for example a lens, at least one mirror element associated with the at least one optical unit, which mirror element is a micromirror array, a DMD chip, for example, and a light imaging system associated with the at least one micromirror array. DMD is an acronym used for "Digital Micromirror Device", thus for a micromirror array or micromirror array Such a micromirror array has very small dimensions, typically on the order of 10 mm In a DMD, micromirror actuators are arranged in a matrix, with each individual mirror element can be tilted by a certain angle, for example 20 ° A headlight based on a micromirror array is described, for example, in DE 195 30 008 A1.
    A rapid change in the type of radiated light distribution is possible if each individual mirror of the at least one micromirror array can be controlled by the control unit associated with the main light module.
    A roll angle compensation can be realized with the DMD system if the control unit assigned to the main light module is set up to receive a data record in which data on the bank angle and / or the speed and / or acceleration of the vehicle are contained To determine the data of a banking angle and / or the speed and / or acceleration of the vehicle and to control the at least one micromirror array such that the main light module emits light to form the modified fundamental light distribution.
    In order to achieve an even higher resolution and homogeneity of the light image, it may be advantageous if the main light module is designed as a laser scanning end system.
    Use of lasers in headlamps is known in the art. In order to produce a light image, a laser light beam generated by a laser light source is deflected via a mirror onto a phosphor, which phosphor absorbs the laser light and fluorescence light of a different wavelength, for example a lower energy wavelength than the wavelength of the laser light, for example 450 nanometers in semiconductor lasers , emitted in all spatial directions. In this case, at least a part of this light is imaged by means of a phosphor associated with the light imaging system in the area in front of the headlight. If the mirror deflecting the laser light is pivotably mounted about two axes, then it is possible to produce a two-dimensional luminous area on the phosphor by "writing" or "scanning" with the deflected laser light beam on the phosphor. first rotate the mirror about one axis in a certain direction, then rotate the mirror about another axis, and then rotate the mirror back around the axis of rotation. In this case, two mutually offset luminous substantially straight lines are generated on the phosphor. Attempts have been made in the prior art to ensure that the angle of incidence of the laser beam on the mirror is as small as possible.
    It may thus be advantageous if the laser scanning end system at least one controllable by the control unit laser light source, which is at least one laser light source for emitting a laser light beam, at least one rotatably mounted about an axis of rotation and controllable by the control unit mirror, which axis of rotation through the geometric center of the at least one mirror extends, one of a reflective surface of the at least one mirror upstream phosphor plate and a light imaging system comprises.
    Furthermore, it may be advantageous for Justierunggriinden if the at least one laser light source, the at least one mirror and the phosphor plate in the laser scanning system are arranged such that the laser beam emitted from the at least one laser light source is substantially in the geometric center of the meets at least one mirror and the laser light beam reflected from the at least one mirror is incident on a surface of the phosphor plate.
    It is expedient to illuminate with the at least one reflected laser beam by rotation of the at least one mirror gekrtimmte lines instead of straight lines on the phosphor. A straight line would only arise if the mirror surface normal vector, i. a normal vector which is orthogonal to the specular surface of the mirror, encloses a right angle with the axis of rotation (thereby, the mirror surface normal vector forms an imaginary circle during rotation of the mirror), and the irradiated laser light beam is in the plane of rotation of the specular surface normal vector.
    Accordingly, in a preferred embodiment it can be provided that the mirror surface normal vector of the at least one mirror encloses an angle with the axis of rotation.
    In addition, it may be advantageously provided that the laser light beam emitted by the at least one laser light source is incident on the at least mirror at an angle of incidence dependent on a rotational position of the at least one mirror, the angle of incidence being greater than zero, irrespective of the rotational position of the at least one mirror. In this embodiment, the at least one reflected laser light beam always illuminates a curved line, for example in the form of a hyperbola or a parabola, on the phosphor. The strength of the curvature depends on how small or large the angle of incidence can become as a function of the rotational position of the at least one mirror.
    Whether the point illuminated by the at least one deflected laser light beam on the phosphor plate during the rotation of the at least one mirror of a hyperbola or a parabola depends on the orientation of the axis of rotation of the at least one mirror with respect to the phosphor plate surface normal. Thus, in a preferred embodiment, it can be provided that the axis of rotation of the at least one mirror encloses a right angle with the phosphor plate surface normal.
    In a further concrete embodiment it can be provided that the axis of rotation of the at least one mirror runs parallel to the phosphor plate surface normal.
    In order to modify the modifiable basic light distribution to a modified basic light distribution according to the traffic situation with the laser scanning end system, it may be advantageous for the control unit assigned to the main light module to be configured to receive a data record which data about the Slope and / or the speed and / or acceleration of the vehicle comprises, from the data to determine a banking angle and / or the speed and / or acceleration of the vehicle and to control the at least one laser light source and the at least one mirror such that the Main light module emits light to form the modified fundamental light distribution.
    Furthermore, in a particularly practicable embodiment it can be provided that the apron light module at least one light source comprises a reflector associated with the at least one light source, preferably a free-form reflector. The number of facets can vary, depending on the requirements for homogeneity of the partial light distribution. For example, the free-form reflector may have more than six or more than ten facets.
    The first light distribution complies with the legal requirements if the at least one light source is designed as a lamp, for example a standard lamp ECE-R37 incandescent lamp or a standard ECE-R99 corresponding gas discharge lamp.
    With regard to size and performance, it is expedient if the at least one light source is formed from one, two or more LEDs.
    A particularly pleasant and homogeneous first light distribution is obtained if the apron light module comprises at least one light source, preferably one, two or more LED light sources, and a lens associated with the at least one light source, preferably a collimator lens, for example a TIR lens.

    Chip) formed mirror element. 1 shows a schematic structure of a main light module 3 which has at least one light source 31, at least one beam-forming imaging unit 32 assigned to the at least one light source 31 (for example consisting of one or more lenses), at least one micromirror array 33 associated with the beam-forming imaging unit 32, for example, a DMD chip, and a light imaging system 34 associated with the at least one micromirror array 33. The light generated by the at least one light source 31 is directed onto the micromirror array 33 with the aid of the beam-shaping imaging unit 32. Each individual micromirror 35 of the micromirror array 33 is arranged on an adjusting element 36. The adjusting elements 36 of the micromirror array 33 can be controlled by means of a control unit 7. By moving a micromirror 35 with the aid of the associated actuator 36, the Anted of the light deflected in the direction of the light imaging system can be increased or reduced and thereby the luminous intensity of a pixel, i. a micromirror photo, are varied continuously.
    Reference is now made to Figs. 3-6 which relate to embodiments of the headlamp in which the main light module has at least one laser light source. 3 shows a schematic structure of a laser scanning end system 40 according to the invention in a headlight, not shown here, with a rotation axis 42 of the mirror perpendicular to the optical axis OA of a light imaging system 47 43, wherein the mirror 43 is rotatably mounted in Fig. 4 about the axis of rotation 42 parallel to the optical axis OA of the light imaging system 47. Different orientations of the axis of rotation with respect to the optical axis OA are conceivable. As already mentioned, two examples, with which, however, the variety of orientation possibilities is not exhausted, in Fig. 3 - the rotation axis 42 is perpendicular to the optical axis OA - and in Fig. 4 - the rotation axis 42 is parallel to the optical axis OA - shown. The light imaging system 47 is arranged such that its optical axis OA is parallel to the direction of the normal vector nL of the phosphor plate surface 50. The laser light source 41 and the mirror 43 are controllable by a control unit 7, i. the control unit 7 is set up to vary the angle of inclination a of the mirror 43 relative to the axis of rotation 42 and / or the rotation of the mirror 43 and / or the intensity of the emitted laser beam 48. An activated laser light source 41 emits a laser light beam 48, which is incident on the mirror at a certain angle of incidence δ, which angle of incidence δ depends on the rotational position of the mirror 43. The emitted laser light beam 48 is reflected by the mirror 43 and directed in the direction of the phosphor plate 50. When a reflected (deflected) laser light beam 49 impinges on the phosphor plate 46, a luminous spot emitting light in all spatial directions is generated by fluorescence, at least part of which light is captured by the light imaging system 47 and into an area in front of the headlamp as white light (superposition of white light) scattered blue laser light and fluorescence radiation) is directed. In this way, one brings various areas of the phosphor plate 46 to light, the shape of these areas by the arrangement of the normal vector ns of the mirror 43, for example by the inclination angle a to the rotation axis 42, relative to the direction of the emitted laser light beam 48 and the optical axis OA of the light imaging system 47 is predetermined. Specifically, in FIGS. 3 and 4, two substantially one-dimensional illuminated regions of the phosphor plate 46 are shown, which arise during rotation of the mirror 43 about its axis of rotation 42. These illuminated areas may be either part of a closed curve, such as a circle or ellipse, or part of a non-closed curve, e.g. a parabola or hyperbola, be formed.
    In FIGS. 5 and 6, the structure serves the purpose of illuminating two-dimensional regions on the phosphor plate 46. Various embodiments are conceivable here. FIG. 5 shows a schematic structure of a laser scanning end system 40 according to the invention with a mirror 43 and at least two, preferably with a plurality of laser light sources LI, L2,... LN associated with the mirror 43. When several laser light sources LI, L2,... LN are simultaneously switched on, these laser light sources illuminate the mirror 43. This results in a plurality of reflected laser light beams R1, R2,... RN which strike the phosphor plate 46 and a two-dimensional one upon rotation of the mirror 43 In a further embodiment shown in Fig. 6, the laser scanning end system 40 comprises at least two, preferably a plurality of mirrors SI, S2, ... SN and at least two, preferably a plurality of laser light sources LI, L2, ... LN associated with the mirrors SI, S2, ... SN Each laser mirror is assigned to each mirror, which laser light source irradiates this mirror, whereby a reflected laser light beam is produced It is quite possible that two or more laser light sources irradiate the same mirror to be favoured. Furthermore, all the mirrors in FIG. 4 SI, S2,... SN have the same axis of rotation 42 about which axis of rotation 42 the mirrors SI, S2,... SN are rotatably mounted. This should not be understood as a limitation: Embodiments are possible in which each mirror is rotatably mounted about its own axis of rotation. In addition, it may be advantageous to arrange the individual axes of rotation relative to one another and to the phosphor plate surface normal nL such that the resulting luminous area on the phosphor plate 46 has predetermined shape properties, for example the curvature or the shape of the lines delimiting the luminous area.
    The intensity of the lasers 41, LI, L2,... LN can be varied as a function of the mirror positions by means of a control unit 7 assigned to the lasers. As a result, spatially variable light distributions can be realized, which allow adaptation of the radiated light distribution to the traffic situation and / or surroundings of the vehicle. In this way, for example, an adapted to the road overall light distribution can be generated.
    The total light distribution results as a superimposition of a first radiant light emitted by an apron light module and a second modifiable radiant light distribution radiated by the main light module. FIG. 7 shows a partial light distribution 2, which is substantially homogeneous and has a rectilinear upper apron HD boundary 5. In this case, adjoins the partial light distribution on a set up at a certain distance orthogonal to the optical axis of the headlight Messschirm on an x-axis X of an orthogonal coordinate system from below, and, as already discussed, the XY system is a headlight coordinate system and whose x-axis X is at the legally prescribed subsidence 0.57 ° in ECE space (0.40 ° in the US) below the usual horizontal or hh-line hh (Figure 8). In addition, the partial light distribution has a characteristic width B, which is substantially 80 °, and is substantially in a horizontal angle range of -40 ° to + 40 °. The horizontal width of the partial light distribution should be greater than +/- 30 ° in any case.
    A general basic light distribution is shown in FIG. In this case, two coordinate systems are plotted in FIG. 8 for the purpose of clarifying the lowering of the x-axis X with respect to the hh-line hh. The second axis of both coordinate systems is equal to vv, Y. The intersection of the hh line hh and the vv line vv is the HV point. The basic light distribution shown is designed as a partial high beam distribution 4. The partial high beam distribution has a characteristic width BG of approximately 20 ° - 24 ° and is substantially in a range of -12 ° to + 12 ° horizontally, with its lower limit U in the range between vv = -2 ° and vv = -3 °. It is not recommended to lower the lower limit U than vv = -3 °, since in this case the implementation of a set conformal overall light distribution turns out to be very difficult.
    A dimmed total light distribution A in a straight line travel is shown in FIG. 9, which is generated as a superposition of the basic light distribution 4 and the partial light distribution 2. In this case, the basic light distribution 4 generated on the basis of the main light module of FIG. 1 comprises regions B1, B2, B3 and can be generated, for example, by dimming certain regions of the partial high-beam distribution of FIG. The difference between the areas Bl, B2 and B3 is their luminous intensity, so the first area Bl is more strongly illuminated than the second area B2 and the second area B2 is more strongly illuminated than the third area B3. A total high beam distribution F generated by the main light module of FIG. 1 when traveling straight ahead is shown in FIG. The transitions of the luminous intensity are executed running, i. the gradient between the areas shows no erratic behavior. The total high beam distribution F is formed as a superposition of the partial light beam distribution 4 formed, three areas Bl, B2, B3 comprehensive basic light distribution and the partial light distribution 2. The area Bl has a maximum light intensity range 6.
    FIG. 11 shows a modified basic light distribution 4 'produced by means of the main light module of FIG. 1, adapted to the inclined position of the vehicle. The modified basic light distribution 4 'completes the partial light distribution to a low-beam distribution A adapted to the banking angle of the vehicle. The motorcycle tilt during cornering is given by an angle-the banking angle w. When cornering, the motorcycle and hence the headlamp including the headlamp coordinate system XY is inclined to the original position. The inclination angle w is equal to the rotation angle of the headlight coordinate system in cornering XY with respect to the headlight coordinate system when traveling straight ahead ΧΎ. In Fig. 11, the roll angle compensation function is realized in a left turn: the HD limit of the low beam distribution is parallel to the horizon hh and the oblique increase of the HD limit follows the course of the road. Each square segment in the light image generated by means of a single micromirror 35 of the micromirror array 33. The modified fundamental light distribution 4 'comprises three regions B1, B2 and B3 and results essentially from a parallel displacement along the hh line hh of the fundamental light distribution 4 of FIG. 9.
    In FIG. 12, a total high beam distribution F adapted to the banking angle of the vehicle (as expressed by the inclination angle w) is shown using the main light module of FIG. 1. The total high beam distribution F is formed as a superposition of the partial light distribution 2 and the three basic areas Bl, B2 and B3 formed as a partial high beam distribution comprising modified basic light distribution 4 '. The modified basic light distribution 4 'results essentially from a parallel displacement along the hh-line hh of the basic light distribution 4 of FIG. 10. As a result, each micromirror 35 of the micromirror array 33 can be individually controlled by means of a control unit 7, not shown here Dimming or hiding certain areas of the photograph. Such a blanked area B4 is shown in FIG. 13 for the basic light distribution 4 when driving straight ahead and in FIG. 14 for the modified basic light distribution 4 'during a left turn. The hidden area B4 corresponds to an oncoming lane in right-hand traffic. As a result, it is a glare-free overall high beam distribution realized with the curve mode and with the roll angle compensation function. In general, the properties of the micromirror array 33 make it possible to largely control the luminous intensity in predetermined regions of the light image. This makes it possible to adapt the generated light distribution to almost any traffic situation and traffic region - for example, left or right traffic, Europe (ECE regulations) or North America FMVSS in the US and CMVSS in Canada.
    Finally, an overall high-beam distribution F generated by the main light module of FIG. 5 or FIG. 6 during a straight-ahead travel (FIG. 15) and an overall high-beam light distribution F 'modified according to the curve during a left-hand turn (FIG. 16) are shown. wherein the modified total high beam distribution F 'from the total high beam distribution F results by a parallel shift along the horizon hh. As a result of this parallel displacement, the maximum light intensity range 6 of the modified total high beam distribution F 'is still on the road. The Kriimmung the illustrated light distribution can be adapted to the skew w of the motorcycle and thereby the low beam distribution with the cornering light mode and with the roll angle compensation function can be realized.
