Definitions

  • the invention relates to a motor vehicle headlight, comprising a light source, projection optics and a holder, the light source being connected to the holder and being set up to emit light in the direction of a projection axis by means of the projection optics.
  • the invention relates to a motor vehicle which comprises at least one motor vehicle headlight according to the invention.
  • the desire to be able to project a high-resolution, homogeneous light image onto the road is becoming more and more important.
  • the term "roadway” is used here for the sake of simplicity, because of course it depends on the local conditions whether a photograph is actually on the roadway or extends beyond it.
  • the light image in the sense used corresponds to a projection onto a vertical surface in accordance with the relevant standards that relate to vehicle lighting technology.
  • 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 generated by a light source is reflected in the emission direction of the headlight.
  • Such lighting devices are advantageous in vehicle construction because of their very flexible lighting functions, since the illuminance can be individually controlled for different lighting areas and any lighting functions with different light distributions can be implemented, such as a low beam light distribution, a cornering light distribution, a city light distribution, a Motorway light light distribution, a cornering light light distribution, a high beam light distribution or the depiction of glare-free high beam.
  • DLP ® Digital Light Processing
  • the so-called Digital Light Processing (DLP ® ) projection technique is used for the micromirror arrangement, in which images are generated in that a digital image is modulated onto a beam of light.
  • the light beam is broken down into sub-areas by a rectangular arrangement of movable micromirrors, also referred to as pixels, and then reflected pixel by pixel either into the projection path or out of the projection path.
  • DMD Digital Micromirror Device
  • a DMD microsystem is a surface light modulator (spatial light modulator, SLM), which consists of micromirror actuators arranged in a matrix, ie tiltable reflecting surfaces, for example with an edge length of about 16 ⁇ m.
  • SLM surface light modulator
  • the mirror surfaces are constructed in such a way that they can be moved under the influence of electrostatic fields.
  • the angle of each micromirror can be adjusted individually and usually has two stable end states, between which it can be switched up to 5000 times within one second.
  • the individual micromirrors can each be controlled by pulse width modulation (PWM), for example, in order to map further states of the micromirrors in the main beam direction of the DMD arrangement, the time-averaged reflectivity of which lies between the two stable states of the DMD.
  • PWM pulse width modulation
  • 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 on which the adjustable individual mirrors are based is Micro-Electro-Mechanical-Systems (MEMS) technology.
  • DMD Digital Micromirror Device
  • AMD Analog Micromirror Device
  • U.S. 2004/202008 A1 discloses a motor vehicle headlight known from the prior art.
  • the object of the invention is to overcome the disadvantages mentioned or to meet the requirements better than is possible with the prior art.
  • a possibility should be created to compensate for component and assembly tolerances and to be able to adjust optical elements with high precision.
  • 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 also includes a lever which, by means of axis elements that form a pivot axis, which is transverse, preferably runs normal to the projection axis, is rotatably connected to the mount, and the frame has at least one lug, which is located between the mount and the lever, and the lever is set up to press on the at least one lug during a rotary movement about the pivot axis, and thereby displacing the frame in the holder along the projection axis.
  • the arrangement according to the invention ensures that the position of the at least one projection optics can be adjusted very finely by the at least one lever. According to the law of the lever, a large displacement of the force arm of the lever, which can be operated with little effort, can be transferred to a smaller displacement of the load arm, which can shift the position of the projection optics with greater force.
  • the invention has great advantages during assembly, since the vehicle headlight does not have to be dismantled into its individual parts to adjust the assemblies, 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 assembly. The extent of the adjustment can be observed in the resulting light pattern of the headlight.
  • At least one flexible, elastic spring element is arranged between the at least one nose and the holder.
  • a preload can be applied to the adjustment connection by means of a flexible spring element, as a result of which the adjustment connection can be set without play.
  • this 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 in this way.
  • At least one connecting element which is preferably a screw, is also arranged between the bracket and the lever and is set up to connect the bracket and the lever to one another. It can thereby be achieved that the connection is finely adjustable.
  • the light source comprises at least one semiconductor light source, in particular an LED or a laser diode.
  • 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.
  • 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, ie a controllable reflector using DLP® technology.
  • the mount includes a guide arranged parallel to the projection axis, which is set up to receive the at least one lug of the frame and to guide the at least one lug of the frame along the guide of the mount.
  • the guide improves the alignment of the projection optics during adjustment.
  • the lever is U-shaped and has two ends, with an opening for receiving axle elements being located at the two ends of the U-shaped lever, through which the pivot axis of the lever runs and at 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 bracket.
  • a connecting element preferably an adjusting screw
  • the U-shaped lever is particularly favorable when the mount and the frame with the projection optics are to be adjustable and adjustable over a large distance.
  • a guide can be used to support this.
  • the U-shaped lever is particularly well suited because the lever can thus have a large lever length in order to achieve a large adjustment range, and the lever can be easily moved by enclosing the arrangement of bracket and frame and thereby blocking the beam path of the light uncircumcised.
  • the lever is ring-shaped and has at least one aperture for receiving at least one axle member through which the pivot axis passes, the aperture being tangential to the mean diameter of the annular lever therethrough. Furthermore an opening for receiving a connecting element, preferably an adjusting screw, is provided on the ring-shaped lever, with which the lever can be connected to the holder.
  • the ring-shaped lever preferably comprises at least one support, which is set up to press on the at least one lug, and the frame forms a common component with the at least one lug.
  • the ring-shaped lever is particularly favorable when the at least one holder and the frame with the projection optics are to be adjustable and displaceable over a small distance.
  • the ring-shaped lever forms a common component with the lug in order to simplify the structure.
  • additional optics are included, which have an optical axis and the additional optics are attached to the holder and the optical axis of the additional optics is preferably located coaxially in the projection axis.
  • the motor vehicle headlight comprises two projection optics with two projection axes and preferably two holders for accommodating 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 when one of the two projection optics is located inside a housing and the other of the two projection optics is located outside of the housing. This allows gradual adjustment to be made as assembly progresses. The second projection optics located on the outside of the housing can then be adapted to the conditions when installed in a vehicle, while the first projection optics is no longer adjusted.
  • further projection optics can be provided in the form of additional optics, which are fastened in the holder.
  • additional optics By adjusting the additional optics with respect to the projection optics, the optical parameters of the overall optics, which are formed by one or more projection optics and additional optics, can be set particularly easily.
  • the two projection axes of the two projection optics are at an angle to one another, the angle preferably being located only in a horizontal plane in the installation position of the motor vehicle headlight and preferably between 0° and 10° amounts to.
  • a motor vehicle which comprises at least one motor vehicle headlight according to the invention.
  • the motor vehicle headlight according to the invention can be adapted and adjusted to the installation situation and position in a motor vehicle in a particularly simple manner.
  • a headlight contains many other parts that are not shown and that allow sensible use in a motor vehicle, such as in particular a car or motorcycle.
  • cooling devices for components, control electronics or other optical elements are not shown.
  • FIGS Figures 1 to 11 An installation position in a vehicle is not shown in a separate figure for a headlight 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 gained by the headlight according to the invention when installed in a vehicle results from the description of the exemplary embodiments according to FIGS Figures 1 to 11 .
  • a motor vehicle headlight 101 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.
