    The invention relates to a device comprising a light source, projection optics and a holder, the light source being connected to the holder and being designed to emit light in the direction of a projection axis by means of the projection optics.
    The invention further relates to a motor vehicle which comprises at least one motor vehicle headlight according to the invention.
    In the development of the current headlight systems, the desire to be able to project a high-resolution, homogeneous light image onto the track is increasingly in the foreground. The term “Lahrbahn” is used here for a simplified representation, because of course it depends on the local conditions whether a photograph is actually on the Lahrbahn or extends beyond it. In principle, the photograph in the sense used corresponds to a projection onto a vertical surface in accordance with the relevant standards relating to automotive lighting technology.
    In order to meet this need, headlights have been developed, among other things, in which a variably controllable reflector surface is formed from a plurality of micromirrors and a light emission that is generated by a light source is reflected in the direction of radiation of the headlight. Such lighting devices are advantageous in vehicle construction because of their very flexible lighting functions, since the illuminance can be regulated individually for different lighting areas and any lighting functions can be implemented with different light distributions, such as a low beam light distribution, a cornering light light distribution, a city light light distribution, one Motorway light light distribution, a cornering light light distribution, a learning light distribution or the mapping of glare-free learning light.
    The so-called digital light processing (DLP®) projection technology is used for the micromirror arrangement, in which images are generated by modulating a digital image onto a light beam. It is represented by a rectangular
    2.29
    P15358
    Arrangement of movable micromirrors, also referred to as pixels, the light beam broken down into partial areas and then reflected pixel-wise either into the projection path or out of the projection path.
    This technology is based on an electronic component that contains the rectangular arrangement in the form of a matrix of mirrors and their control technology and is referred to as the “digital micromirror device (DMD)”.
    A DMD microsystem is an area light modulator (Spatial Light Modulator, SLM) which consists of micro-mirror actuators arranged in a matrix, i.e. tiltable reflecting surfaces, for example with an edge length of approximately 16 pm. The mirror surfaces are constructed in such a way that they are unfortunately movable due to the influence of electrostatic. Each micromirror can be individually adjusted in angle and generally has two stable end states, between which it is possible to switch up to 5000 times within a second. The individual micromirrors can, for example, each be controlled by pulse width modulation (PWM) in order to image further states of the micromirrors in the main beam direction of the DMD arrangement, the reflectivity of which is averaged over time between the two stable states of the DMD. The number of mirrors corresponds to the resolution of the projected image, whereby a mirror can represent one or more pixels. DMD chips with high resolutions in the megapixel range are now available. The technology underlying the adjustable individual mirrors is the micro-electro-mechanical systems (MEMS) technology.
    While the DMD technology has two stable mirror states, and the reflection factor can be set by modulating between the two stable states, the “Analog Micromirror Device (AMD) technology has the property that the individual mirrors can be set in variable mirror positions, which there are in a stable state.
    With arrangements in DLP® technology, it is important that the individual assemblies of a vehicle headlight are assembled with high precision, that is, with very low tolerances, which are far above the requirements for conventional vehicle headlights. The individual assemblies, for example light sources, reflectors or
    3.29
    P15358
    Projection lenses must be positioned or adjusted very precisely in relation to one another, for example to prevent blurring regarding the focus, incorrect images, falling below the required standard values and incorrect light. This is currently not necessary in vehicle headlights according to the prior art.
    Furthermore, adjustment devices for assemblies often have a game in the
    Adjustment connections of the optical components, which can adversely affect the optical properties of the headlamp.
    It is an object of the invention to overcome the disadvantages mentioned or to better meet the requirements than is possible in the prior art. In addition, a possibility is to be created to compensate component and assembly tolerances and to be able to adjust optical elements with high precision.
    The object of the invention is achieved by a motor vehicle headlight of the type mentioned at the outset, in that the projection optics are fastened in a frame which is movably arranged in the holder and further comprises a lever which by means of axle elements which form a pivot axis which extends transversely, preferably runs normal to the projection axis, is rotatably connected to the holder, and the frame has at least one lug, which is located between the holder and the lever, and the lever is set up to press the at least one lug during a rotational movement about the pivot axis , and thereby the frame in the bracket along the
    To move the projection axis.
    It is achieved by the arrangement according to the invention that the position of the at least one projection optics can be adjusted very finely by the at least one lever. According to the lever law, a large path of the force arm of the lever, which can be actuated with little force, can be transferred to a smaller path of the load arm, which can shift the position of the projection optics with greater force.
    It can be achieved that a favorable design of the frame, which together with the at least one holder provides a displaceable mounting of the at least one projection optics, and that the solution according to the invention is highly precise
    4.29
    P15358
    Adjustment or adjustment of assemblies in a vehicle headlight, such as light sources, reflectors or lenses.
    Furthermore, a very compact design is possible due to the inventive design of the vehicle headlight.
    In addition, the invention has great advantages in assembly, since the
    Vehicle headlights for adjusting the assemblies do not have to be disassembled into their individual parts or the assemblies do not have to be assembled successively in order to be able to be adjusted to one another. After complete assembly, it is possible to adjust an entire arrangement. The extent of the adjustment can be observed in the resulting light image of the headlight.
    In a further development of the invention, at least one flexible, elastic spring element is arranged between the at least one nose and the holder. By means of a resilient spring element, a pretension can be applied to the adjustment connection, whereby a play-free adjustment of the adjustment connection is made possible. This also creates a connection that can be fixed in any position, which means that the installation conditions can be taken into account very individually and precisely. These installation conditions can be caused by tolerances in the geometry or assembly of individual assemblies, which should be reduced or compensated for as best as possible. An installation situation of the headlight in a vehicle can also be taken into account.
    It is particularly advantageous if at least one connecting element, which is preferably a screw, is arranged between the holder and the lever and is configured to connect the holder and the lever to one another. This enables the connection to be finely adjusted.
    It is favorable if the light source comprises at least one semiconductor light source, in particular an LED or a laser diode. This enables a particularly compact construction of the headlight to be achieved. For this reason, it is also advantageous if the projection optics comprise at least one optical lens and a controllable reflector, in particular a DMD, is arranged between the light source and the projection optics.
    5.29
    P15358
    In the case of controllable reflectors in particular, the accuracy requirements for the entire optical arrangement are particularly high, which is why the arrangement according to the invention can be used very advantageously with a DMD, that is to say a controllable reflector in DLP® technology.
    It is particularly advantageous if the holder comprises a guide arranged parallel to the projection axis, which is designed to receive the at least one nose of the frame and to guide the at least one nose of the frame along the guide of the holder. The guidance improves the alignment of the projection optics during the adjustment.
    A suitable choice of the shape of the bracket enables uniform, symmetrical power transmission.
    In an advantageous embodiment of the invention, the lever is U-shaped and has two ends, an opening for receiving axle elements being located at each of the two ends of the U-shaped lever, through which the pivot axis of the lever runs and on the U- shaped lever further an opening for receiving a connecting element, preferably an adjusting screw, is provided, with which the lever can be connected to the holder. Several openings are also possible, each for receiving connecting elements. The middle of the lever is located between the two ends of the lever.
    The U-shaped lever is particularly favorable when the holder and the frame with the projection optics are to be adjustable and adjustable over a long distance. A guide can be used to support this. The U-shaped lever is particularly well suited because the lever can have a large lever length in order to achieve a large adjustment range, and the lever can be easily implemented by gripping the arrangement of the holder and frame and thereby the beam path of the Light not pruned.
    In a further advantageous, alternative embodiment of the invention, the lever is ring-shaped and has at least one opening for receiving at least one axle element, through which the pivot axis runs, the opening running tangentially to the mean diameter of the ring-shaped lever. Further is
    6.29
    P15358 an opening for receiving a connecting element, preferably an adjusting screw, is provided on the annular lever, with which the lever can be connected to the holder. The annular lever preferably comprises at least one support which is designed to press on the at least one nose and the frame forms a common component with the at least one nose.
    The ring-shaped lever is particularly favorable if the at least one holder and the frame with the projection optics are to be adjustable and adjustable over a small path.
    It is also advantageous if the annular lever forms a common component with the nose in order to simplify the construction.
    Furthermore, it is advantageous if an additional optical system is included which has an optical axis and the additional optical system is fastened to the holder and the optical axis of the additional optical system is preferably located coaxially in the projection axis.
    In a further development of the invention, it is provided that the motor vehicle headlight comprises two projection optics with two projection axes and preferably two holders for receiving the two projection optics. It can thereby be achieved that the optical parameters of the projection optics can be adjusted very flexibly. This is particularly advantageous if one of the two projection optics is located within a housing and the other of the two projection optics is located outside the housing. This allows a gradual adjustment according to the progress in assembly. The second projection optics located on the outside of the housing can then be adapted to the conditions of installation in a vehicle, while the first projection optics are no longer adjusted.
    In a further development of the invention, further projection optics can be provided in the form of additional optics, which are fastened in the holder. By adjusting the additional optics with respect to the projection optics, it is achieved that the optical parameters of the overall optics, which are formed by one or more projection optics and additional optics, can be set particularly easily.
    7.29
    P15358
    It is advantageous for the flexible adjustment and setting of the optical parameters if the two projection axes run coaxially or in parallel.
    In a development of the invention with regard to the arrangement of the optical elements, it is advantageous if the two projection axes of the two projection optics have an angle with one another, the angle preferably being located only in a horizontal plane in the installed position of the motor vehicle headlight and preferably between 0 ° and 10 ° is.
    In a further development of the invention, a motor vehicle is provided which comprises at least one motor vehicle headlight according to the invention. It can thereby be achieved that the motor vehicle headlight according to the invention can be adapted and adjusted particularly easily to the installation situation and location in a motor vehicle.

    An exemplary embodiment of the invention will now be explained in more detail with reference to FIGS. 1 to 11. In particular, parts which are important for the invention are shown in a headlight, it being clear that a headlight also contains many other parts, not shown, which enable sensible use in a motor vehicle, such as in particular a car or motorcycle. For the sake of clarity, cooling devices for components, control electronics or other optical elements are not shown, for example.
    An installation position in a vehicle for a headlight according to the invention is not shown in a separate figure according to the following description, since the installation position of the headlight according to the invention does not differ from the known prior art. The adjustability obtained by the headlight according to the invention when installed in a vehicle results from the description of the exemplary embodiments according to FIGS. 1 to 11.
    1 and 2, a motor vehicle headlight 101 is shown, comprising a light source 105, a first projection optics 102 and a second projection optics 202 and a first holder 106 and a second holder 206, the light source 105 being mechanically firmly connected to the holders 106 and 206 is. Furthermore, the light source 105 is set up to emit in the direction of a first projection axis 104 or a second projection axis 204 by means of the projection optics 102 and 202. Here there is an angle 304 between the projection axes 104 and 204. In this example, the angle 304 is located in a horizontal plane, starting from an installation position of the headlamp in a vehicle, and is between 0 ° and 10 °, depending on the version. For other exemplary embodiments, however, it can make sense that the two axes are located coaxially or provide an angle 304 in an arbitrarily oriented spatial plane. Between the light source 105 and the projection optics 102 and 202 there is an electronically controllable reflector 113 in the form of a micromirror arrangement, for example a DLP® or a DMD, which, depending on the control, emits the light emitted by the light source 105 in the direction of the projection axes 104 and 204 can reflect. Those mirrors of the controllable reflector 113 that so
    9.29
    P15358 that the light is not reflected in the direction of the projection axis 104, the light can alternatively reflect in the direction of an absorber 114.
    In this exemplary embodiment of the invention, two projection optics 102 and 202 with two projection axes 104, 204 are used, the two projection axes 104, 204 running coaxially. Learners are also included in other components, such as the brackets 106, 206 for receiving the two projection optics 102, 202 in two different versions. However, only projection optics can also be used in a motor vehicle headlight in order to implement the structure, for example, more compactly or more cost-effectively. The embodiment shown is characterized by a particularly flexible adjustability of the optical parameters of the projection optics or the overall projection optics, which is formed by the two projection optics. It is clear that when installed in a vehicle two
    Motor vehicle headlights 101 can be installed.
    The light source 105 is connected to a heat sink in order to dissipate the heat loss generated by the light source 105. The light source 105 can comprise one or more light-generating components, such as semiconductor light sources, in particular LEDs or laser diodes, and primary optics, which include one or more optical lenses or diaphragms. A means for light conversion from a first wavelength range to a second wavelength range, for example a conversion phosphor, can also be included.
    The controllable reflector 113 is mounted here on a printed circuit board, which can comprise further electronic components for controlling the controllable reflector 113 or mechanical elements.
