Description

Die Erfindung betrifft einen Kraftfahrzeugscheinwerfer, umfassend eine Lichtquelle, eine Projektionsoptik und eine Halterung, wobei die Lichtquelle mit der Halterung verbunden ist und eingerichtet ist, mittels der Projektionsoptik Licht in Richtung einer Projektionsachse abzustrahlen.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.

Ferner betrifft die Erfindung ein Kraftfahrzeug, das zumindest einen erfindungsgemäßen Kraftfahrzeugscheinwerfer umfasst.Furthermore, the invention relates to a motor vehicle which comprises at least one motor vehicle headlight according to the invention.

Bei der Entwicklung der gegenwärtigen Scheinwerfersysteme steht immer mehr der Wunsch im Vordergrund, ein möglichst hochaufgelöstes, homogenes Lichtbild auf die Fahrbahn projizieren zu können. Der Begriff "Fahrbahn" wird hier zur vereinfachten Darstellung verwendet, denn selbstverständlich hängt es von den örtlichen Gegebenheiten ab, ob sich ein Lichtbild tatsächlich auf der Fahrbahn befindet oder auch darüber hinaus erstreckt. Prinzipiell entspricht das Lichtbild im verwendeten Sinn einer Projektion auf eine vertikale Fläche entsprechend der einschlägigen Normen, die sich auf die KFZ-Beleuchtungstechnik beziehen.In the development of current headlight systems, 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. In principle, 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.

Um diesem Bedürfnis zu entsprechen, wurden unter anderem Scheinwerfer entwickelt, in denen eine variabel ansteuerbare Reflektorfläche aus einer Mehrzahl von Mikrospiegeln gebildet ist und eine Lichtemission, die von einer Lichtquelle erzeugt wird, in Abstrahlrichtung des Scheinwerfers reflektiert. Derartige Leuchteinrichtungen sind im Fahrzeugbau wegen ihrer sehr flexiblen Lichtfunktionen vorteilhaft, da für unterschiedliche Leuchtbereiche die Beleuchtungsstärke individuell geregelt werden kann und beliebige Lichtfunktionen mit unterschiedlichen Lichtverteilungen realisiert werden können, wie beispielsweise eine Abblendlicht-Lichtverteilung, eine Abbiegelicht-Lichtverteilung, eine Stadtlicht-Lichtverteilung, eine Autobahnlicht-Lichtverteilung, eine Kurvenlicht-Lichtverteilung, eine Fernlicht-Lichtverteilung oder die Abbildung von blendfreiem Fernlicht.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 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.

Für die Mikrospiegelanordnung kommt die sogenannte Digital Light Processing (DLP®) Projektionstechnik zur Anwendung, bei der Bilder dadurch erzeugt werden, dass ein digitales Bild auf einen Lichtstrahl aufmoduliert wird. Dabei wird durch eine rechteckige Anordnung von beweglichen Mikrospiegeln, auch als Pixel bezeichnet, der Lichtstrahl in Teilbereiche zerlegt und anschließend pixelweise entweder in den Projektionsweg hinein oder aus dem Projektionsweg hinaus reflektiert.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.

Basis für diese Technik bildet ein elektronisches Bauteil, das die rechteckige Anordnung in Form einer Matrix von Spiegeln und deren Ansteuerungstechnik enthält und als "Digital Micromirror Device" (DMD) bezeichnet wird.The basis for this technology is 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 a "Digital Micromirror Device" (DMD).

Bei einem DMD-Mikrosystem handelt es sich um einen Flächenlichtmodulator (Spatial Light Modulator, SLM), der aus matrixförmig angeordneten Mikrospiegelaktoren, das heißt verkippbaren spiegelnden Flächen besteht, beispielsweise mit einer Kantenlänge von etwa 16 µm. Die Spiegelflächen sind derart konstruiert, dass sie durch die Einwirkung elektrostatischer Felder beweglich sind. Jeder Mikrospiegel ist im Winkel einzeln verstellbar und weist in der Regel zwei stabile Endzustände auf, zwischen denen innerhalb einer Sekunde bis zu 5000-mal gewechselt werden kann. Die einzelnen Mikrospiegel können beispielsweise jeweils durch eine Pulsweiten-Modulation (PWM) angesteuert werden, um in der Hauptstrahlrichtung der DMD-Anordnung weitere Zustände der Mikrospiegel abzubilden, deren zeitlich gemittelte Reflektivität zwischen den beiden stabilen Zuständen des DMD liegt. Die Anzahl der Spiegel entspricht der Auflösung des projizierten Bilds, wobei ein Spiegel ein oder mehrere Pixel darstellen kann. Mittlerweile sind DMD-Chips mit hohen Auflösungen im Megapixel-Bereich erhältlich. Den verstellbaren Einzelspiegeln zugrunde liegende Technologie ist die Micro-Electro-Mechanical-Systems-(MEMS) Technologie.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 μm. 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. 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.

Während die DMD-Technologie zwei stabile Spiegel-Zustände aufweist, und durch Modulation zwischen beiden stabilen Zuständen der Reflexionsfaktor eingestellt werden kann, weist die "Analog Micromirror Device" (AMD) Technologie die Eigenschaft auf, dass die Einzelspiegel in variablen Spiegelpositionen eingestellt werden können, die dort jeweils in einem stabilen Zustand sind.While DMD technology has two stable mirror states and the reflection factor can be set by modulation 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 are in a stable state there.

Bei Anordnungen in DLP®-Technologie ist es wichtig, dass die einzelnen Baugruppen eines Fahrzeugscheinwerfers hochpräzise, das heißt mit sehr geringen Toleranzen montiert werden, die weit über den Anforderungen bei konventionellen Fahrzeugscheinwerfern liegen. Die einzelnen Baugruppen, beispielsweise Lichtquellen, Reflektoren oder Projektionslinsen, müssen sehr präzise zueinander positioniert beziehungsweise justiert werden, um beispielsweise Unschärfe den Fokus betreffend, Falschabbildungen, Unterschreiten der erforderlichen Lichtwerte und Fehllicht zu verhindern. Das ist in Fahrzeugscheinwerfern nach dem Stand der Technik derzeit nicht erforderlich.With arrangements in DLP ® technology, it is important that the individual components of a vehicle headlight are assembled with high precision, ie with very small tolerances that far exceed the requirements for conventional vehicle headlights lie. The individual assemblies, such as light sources, reflectors or projection lenses, must be positioned or adjusted very precisely in relation to one another in order to prevent, for example, blurriness with regard to the focus, false images, falling below the required light values and false light. This is not currently required in prior art vehicle headlights.

Ferner weisen Justiervorrichtungen für Baugruppen häufig ein Spiel in den Justierverbindungen der optischen Bauelemente auf, was die optischen Eigenschaften des Scheinwerfers ungünstig beeinträchtigen kann. US 2004/202008 A1 offenbart einen aus dem Stand der Technik bekannten Kraftfahrzeugscheinwerfer.Furthermore, adjustment devices for assemblies often have play in the adjustment connections of the optical components, which can adversely affect the optical properties of the headlight. U.S. 2004/202008 A1 discloses a motor vehicle headlight known from the prior art.

Es ist Aufgabe der Erfindung, die genannten Nachteile zu überwinden beziehungsweise die Erfordernisse besser zu erfüllen, als dies der Stand der Technik ermöglicht. Zusätzlich soll eine Möglichkeit geschaffen werden, Bauteil- und Montagetoleranzen zu kompensieren und optische Elemente hochgenau einstellen zu können.The object of the invention is to overcome the disadvantages mentioned or to meet the requirements better than is possible with the prior art. In addition, a possibility should be created to compensate for component and assembly tolerances and to be able to adjust optical elements with high precision.

Die Aufgabe der Erfindung wird durch einen Kraftfahrzeugscheinwerfer der eingangs genannten Art gelöst, indem die Projektionsoptik in einem Rahmen befestigt ist, welcher in der Halterung beweglich angeordnet ist, und ferner ein Hebel umfasst, der mittels Achselementen, die eine Schwenkachse bilden, welche quer, vorzugsweise normal zur Projektionsachse verläuft, mit der Halterung drehbar verbunden ist, und der Rahmen zumindest eine Nase aufweist, die zwischen der Halterung und dem Hebel gelegen ist, und der Hebel eingerichtet ist, bei einer Drehbewegung um die Schwenkachse auf die zumindest eine Nase zu drücken, und dadurch den Rahmen in der Halterung entlang der Projektionsachse zu verschieben.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 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.

Durch die erfindungsgemäße Anordnung wird erreicht, dass die Position der zumindest einen Projektionsoptik durch den zumindest einen Hebel sehr fein eingestellt werden kann. Gemäß dem Hebelgesetz kann ein großer Weg des Kraftarms des Hebels, der mit geringer Kraftaufwendung betätigt werden kann, auf einen kleineren Weg des Lastarms übertragen werden, der mit größerer Kraft die Position der Projektionsoptik verschieben kann.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.

Es kann erreicht werden, dass durch eine günstige Ausführung des Rahmens, der mit der zumindest einen Halterung gemeinsam eine verschiebbare Lagerung der zumindest einen Projektionsoptik vorsieht und dass die erfindungsgemäße Lösung eine hochgenaue Einstellung oder Justierung von Baugruppen in einem Fahrzeugscheinwerfer, wie beispielsweise Lichtquellen, Reflektoren oder Linsen ermöglicht.It can be achieved that through 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 a highly precise Allows setting or adjustment of assemblies in a vehicle headlight, such as light sources, reflectors or lenses.

Ferner ist durch die erfindungsgemäße Ausführung des Fahrzeugscheinwerfers eine sehr kompakte Bauweise möglich.Furthermore, a very compact design is possible due to the design of the vehicle headlight according to the invention.

Außerdem weist die Erfindung bei der Montage große Vorteile auf, da der Fahrzeugscheinwerfer zur Justierung der Baugruppen nicht in dessen Einzelteile zerlegt werden muss beziehungsweise die Baugruppen nicht sukzessive zusammengebaut werden müssen, um aufeinander eingestellt werden zu können. Es ist nach erfolgtem komplettem Zusammenbau möglich, eine gesamte Anordnung zu justieren. Das Ausmaß der Justierung kann im resultierenden Lichtbild des Scheinwerfers beobachtet werden.In addition, 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.

In einer Weiterbildung der Erfindung ist zwischen der zumindest einen Nase und der Halterung zumindest ein nachgiebiges, elastisches Federelement angeordnet. Durch ein nachgiebiges Federelement kann eine Vorspannung auf die Justierverbindung aufgebracht werden, wodurch eine spielfreie Einstellung der Justierverbindung ermöglicht wird. Ferner wird dadurch eine Verbindung geschaffen, die in jeder Position fixiert werden kann, wodurch sehr individuell und präzise auf die Einbaugegebenheiten Rücksicht genommen werden kann. Diese Einbaugegebenheiten können durch Toleranzen in der Geometrie oder Montage einzelner Baugruppen hervorgerufen werden, die reduziert beziehungsweise bestmöglich kompensiert werden sollen. Auch eine Einbausituation des Scheinwerfers in einem Fahrzeug kann dadurch berücksichtigt werden.In a development of the invention, 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. Furthermore, 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.

Es ist besonders vorteilhaft, wenn zwischen der Halterung und dem Hebel ferner zumindest ein Verbindungselement, welches vorzugsweise eine Schraube ist, angeordnet ist, das eingerichtet ist, die Halterung und den Hebel miteinander zu verbinden. Dadurch kann erreicht werden, dass die Verbindung fein justierbar ist.It is particularly advantageous if 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.

Es ist günstig, wenn die Lichtquelle zumindest eine Halbleiterlichtquelle, insbesondere eine LED oder eine Laserdiode umfasst. Dadurch kann ein besonders kompakter Aufbau des Scheinwerfers erreicht werden. Aus diesem Grund ist es ferner günstig, wenn die Projektionsoptik zumindest eine optische Linse umfasst, sowie zwischen der Lichtquelle und der Projektionsoptik ein steuerbarer Reflektor, insbesondere ein DMD, angeordnet ist.It is favorable if the light source comprises at least one semiconductor light source, in particular an LED or a laser diode. As a result, a particularly compact design of the headlight can be achieved. For this reason, it is also favorable 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.

Insbesondere bei steuerbaren Reflektoren sind die Genauigkeitsanforderungen an die gesamte optische Anordnung besonders hoch, weshalb die erfindungsgemäße Anordnung sehr vorteilhaft mit einem DMD, das heißt einem steuerbaren Reflektor in DLP®-Technologie, angewandt werden kann.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, ie a controllable reflector using DLP® technology.

Es ist besonders vorteilhaft, wenn die Halterung eine parallel der Projektionsachse angeordnete Führung umfasst, die eingerichtet ist, die zumindest eine Nase des Rahmens aufzunehmen und die zumindest eine Nase des Rahmens längs der Führung der Halterung zu führen. Die Führung verbessert die Ausrichtung der Projektionsoptik bei der Justierung.It is particularly advantageous if 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.

Durch eine geeignete Wahl der Form des Bügels kann eine gleichmäßige, symmetrische Kraftübertragung ermöglicht werden.An even, symmetrical transmission of force can be made possible by a suitable choice of the shape of the bracket.

In einer vorteilhaften Ausführungsform der Erfindung ist der Hebel U-förmig geformt und weist zwei Enden auf, wobei an den zwei Enden des U-förmigen Hebels jeweils eine Öffnung zur Aufnahme von Achselementen gelegen ist, durch die die Schwenkachse des Hebels verläuft und am U-förmigen Hebel ferner eine Öffnung zur Aufnahme eines Verbindungselements, vorzugsweise eine Justierschraube, vorgesehen ist, mit welchem der Hebel mit der Halterung verbindbar ist. Es sind auch mehrere Öffnungen jeweils zur Aufnahme von Verbindungelementen möglich. Zwischen den zwei Enden des Hebels ist die Hebelmitte gelegen.In an advantageous embodiment of the invention, 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. Several openings are also possible, each for receiving connecting elements. Between the two ends of the lever the middle of the lever is located.

Der U-förmige Hebel ist besonders dann günstig, wenn die Halterung und der Rahmen mit der Projektionsoptik über einen großen Weg verstellbar und justierbar sein sollen. Unterstützend kann dazu eine Führung eingesetzt werden. Der U-förmige Hebel ist deshalb besonders gut geeignet, da der Hebel dadurch eine große Hebellänge aufweisen kann, um einen großen Justierbereich zu erzielen, sowie der Hebel einfach umgesetzt werden kann, indem er die Anordnung von Halterung und Rahmen umgreift und dabei den Strahlengang des Lichts nicht beschneidet.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.

In einer weiteren vorteilhaften, alternativen Ausführungsform der Erfindung ist der Hebel ringförmig geformt und weist zumindest eine Öffnung zur Aufnahme zumindest eines Achselements auf, durch die die Schwenkachse verläuft, wobei die Öffnung tangential zum mittleren Durchmesser des ringförmigen Hebels durch diesen hindurch verläuft. Ferner ist am ringförmigen Hebel eine Öffnung zur Aufnahme eines Verbindungselements, vorzugsweise eine Justierschraube, vorgesehen, mit welchem der Hebel mit der Halterung verbindbar ist. Vorzugsweise umfasst der ringförmige Hebel zumindest eine Auflage, welche eingerichtet ist auf die zumindest eine Nase zu drücken, und der Rahmen mit der zumindest einen Nase ein gemeinsames Bauteil bildet.In a further advantageous alternative embodiment of the invention, 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.

Der ringförmige Hebel ist besonders dann günstig, wenn die zumindest eine Halterung und der Rahmen mit der Projektionsoptik über einen kleinen Weg verstellbar und justierbar sein sollen.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.

Ferner ist es vorteilhaft, wenn der ringförmige Hebel mit der Nase ein gemeinsames Bauteil bildet, um den Aufbau zu vereinfachen.Furthermore, it is advantageous if the ring-shaped lever forms a common component with the lug in order to simplify the structure.

Ferner ist es vorteilhaft, wenn eine Zusatzoptik umfasst ist, welche eine optische Achse aufweist und die Zusatzoptik an der Halterung befestigt ist und vorzugsweise die optische Achse der Zusatzoptik koaxial in der Projektionsachse gelegen ist.Furthermore, it is advantageous if 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.

In einer Weiterbildung der Erfindung ist es vorgesehen, dass der Kraftfahrzeugscheinwerfer zwei Projektionsoptiken mit zwei Projektionsachsen und vorzugsweise zwei Halterungen zur Aufnahme der zwei Projektionsoptiken umfasst. Dadurch kann erreicht werden, dass die optischen Parameter der Projektionsoptik sehr flexibel justierbar sind. Dies ist insbesondere dann vorteilhaft, wenn eine der beiden Projektionsoptiken innerhalb eines Gehäuses gelegen ist, und die andere der beiden Projektionsoptiken außerhalb des Gehäuses gelegen ist. Dadurch kann eine schrittweise Justierung gemäß dem Fortschritt bei der Montage erfolgen. Die außen vom Gehäuse gelegene zweite Projektionsoptik kann sodann an die Gegebenheiten beim Einbau in ein Fahrzeug angepasst werden, während die erste Projektionsoptik nicht mehr justiert wird.In a 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 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.

In einer Weiterbildung der Erfindung kann eine weitere Projektionsoptik in Form einer Zusatzoptik vorgesehen sein, welche in der Halterung befestigt ist. Durch die Justierung der Zusatzoptik bezüglich der Projektionsoptik, wird erreicht, dass die optischen Parameter der Gesamtoptik, die durch eine oder mehrere Projektionsoptiken und Zusatzoptiken gebildet ist, besonders einfach eingestellt werden können.In a 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, the optical parameters of the overall optics, which are formed by one or more projection optics and additional optics, can be set particularly easily.

Es ist dabei günstig für die flexible Justierung und Einstellung der optischen Parameter, wenn die zwei Projektionsachsen koaxial oder parallel verlaufen.It is favorable for the flexible adjustment and setting of the optical parameters if the two projection axes run coaxially or parallel.

In einer Weiterbildung der Erfindung hinsichtlich der Anordnung der optischen Elemente ist es günstig, wenn die zwei Projektionsachsen der zwei Projektionsoptiken einen Winkel untereinander aufweisen, wobei der Winkel bevorzugt nur in einer horizontalen Ebene in Einbaulage des Kraftfahrzeugscheinwerfer gelegen ist und bevorzugt zwischen 0° und 10° beträgt.In a development of the invention with regard to the arrangement of the optical elements, it is favorable if 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.

In einer Weiterentwicklung der Erfindung ist ein Kraftfahrzeug vorgesehen, das zumindest einen erfindungsgemäßen Kraftfahrzeugscheinwerfer umfasst. Dadurch kann erreicht werden, dass der erfindungsgemäße Kraftfahrzeugscheinwerfer besonders einfach an die Einbausituation und Lage in einem Kraftfahrzeug angepasst und justiert werden kann.In a further development of the invention, a motor vehicle is provided which comprises at least one motor vehicle headlight according to the invention. As a result, 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.

Unter Bezugnahme auf Fig. 1 bis Fig. 11 wird nun ein Ausführungsbeispiel der Erfindung näher erläutert. Insbesondere sind für die Erfindung in einem Scheinwerfer wichtige Teile dargestellt, wobei klar ist, dass ein Scheinwerfer noch viele andere, nicht gezeigte Teile enthält, die einen sinnvollen Einsatz in einem Kraftfahrzeug, wie insbesondere einem PKW oder Motorrad, ermöglichen. Der Übersichtlichkeit halber sind daher beispielsweise Kühlvorrichtungen für Bauteile, Ansteuerungselektronik oder weitere optische Elemente nicht gezeigt.With reference to Figures 1 to 11 an embodiment of the invention will now be explained in more detail. In particular, parts that are important for the invention in a headlight are shown, it being clear that 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. For the sake of clarity, for example, cooling devices for components, control electronics or other optical elements are not shown.

Eine Einbaulage in einem Fahrzeug ist für einen erfindungsgemäßen Scheinwerfer gemäß der nachfolgenden Beschreibung nicht in einer gesonderten Figur dargestellt, da sich die Einbaulage des erfindungsgemäßen Scheinwerfers sich nicht vom bekannten Stand der Technik unterscheidet. Die durch den erfindungsgemäßen Scheinwerfer gewonnene Justierbarkeit bei einen Einbau in einem Fahrzeug ergibt sich aus der Beschreibung der Ausführungsbeispiele nach den Fig. 1 bis 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 .

In Fig. 1 und 2 ist ein Kraftfahrzeugscheinwerfer 101 dargestellt, umfassend eine Lichtquelle 105, eine erste Projektionsoptik 102 und eine zweite Projektionsoptik 202 und eine erste Halterung 106 und eine zweite Halterung 206, wobei die Lichtquelle 105 mit den Halterungen 106 und 206 mechanisch fest verbunden ist. Ferner ist die Lichtquelle 105 eingerichtet, mittels den Projektionsoptiken 102 und 202 in Richtung einer ersten Projektionsachse 104, beziehungsweise einer zweiten Projektionsachse 204 abzustrahlen. Hier liegt zwischen den Projektionsachsen 104 und 204 ein Winkel 304 vor. Der Winkel 304 ist in diesem Beispiel in einer horizontalen Ebene gelegen, ausgehend von einer Einbaulage des Scheinwerfers in einem Fahrzeug, und beträgt je nach Ausführung zwischen 0° und 10°. Für andere Ausführungsbeispiele kann es jedoch sinnvoll sein, dass die beiden Achsen koaxial gelegen sind oder einen Winkel 304 in einer beliebig orientierten räumlichen Ebene vorsehen. Zwischen der Lichtquelle 105 und den Projektionsoptiken 102 und 202 ist ein elektronisch steuerbarer Reflektor 113 in Form einer Mikrospiegel-Anordnung, beispielsweise ein DLP® beziehungsweise ein DMD, gelegen, der das von der Lichtquelle 105 emittierte Licht je nach Ansteuerung in Richtung der Projektionsachsen 104 beziehungsweise 204 reflektieren kann. Jene Spiegel des steuerbaren Reflektors 113, die so angesteuert sind, dass das Licht nicht in Richtung der Projektionsachse 104 reflektiert wird, können das Licht alternativ in Richtung eines Absorbers 114 reflektieren.In 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. 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 headlight in a vehicle, and is between 0° and 10°, depending on the design. For other exemplary embodiments, however, it can make sense for the two axes to be located coaxially or for an angle 304 to be provided in a spatial plane with any orientation. An electronically controllable reflector 113 in the form of a micromirror arrangement, for example a DLP ® or a DMD, is located between the light source 105 and the projection optics 102 and 202, which reflects the light emitted by the light source 105 in the direction of the projection axes 104 or 204 can reflect. Those mirrors of the controllable reflector 113 which are controlled in such a way that the light is not reflected in the direction of the projection axis 104, the light can alternatively be reflected in the direction of an absorber 114.

In diesem Ausführungsbeispiel der Erfindung werden zwei Projektionsoptiken 102 und 202 mit zwei Projektionsachsen 104, 204 eingesetzt, wobei die zwei Projektionsachsen 104, 204 koaxial verlaufen. Ferner sind weitere Komponenten, wie die Halterungen 106, 206 zur Aufnahme der zwei Projektionsoptiken 102, 202 auch zweifach in unterschiedlichen Ausführungen umfasst. Es kann in einem Kraftfahrzeugscheinwerfer jedoch auch nur eine Projektionsoptik zum Einsatz kommen, um den Aufbau beispielsweise kompakter oder kostengünstiger zu realisieren. Die gezeigt Ausführungsform zeichnet sich durch eine besonders flexible Einstellbarkeit der optischen Parameter der Projektionsoptiken beziehungsweise der Gesamtprojektionsoptik, die durch die beiden Projektionsoptiken gebildet ist, aus. Es ist klar, dass bei einem Einbau in ein Fahrzeug zwei Kraftfahrzeugscheinwerfer 101 verbaut werden können.In this exemplary embodiment of the invention, two projection optics 102 and 202 with two projection axes 104, 204 are used, with the two projection axes 104, 204 running coaxially. Furthermore, other components, such as the holders 106, 206 for accommodating the two projection optics 102, 202, are also included twice in different designs. However, only one projection optic can be used in a motor vehicle headlight, in order to make the structure more compact or more cost-effective, for example. 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.

Die Lichtquelle 105 ist mit einem Kühlkörper verbunden, um die durch die Lichtquelle 105 erzeugte Verlustwärme abzuführen. Die Lichtquelle 105 kann eine oder mehrere lichterzeugende Bauteile wie Halbleiterlichtquellen, insbesondere LEDs oder Laser-Dioden, sowie ein Primäroptik, die eine oder mehrere optische Linsen oder Blenden beinhaltet, umfassen. Auch ein Mittel zur Lichtkonversion von einem ersten Wellenlängenbereich zu einem zweiten Wellenlängenbereich, beispielsweise ein Konversions-Phosphor, kann beinhaltet sein.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 include 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.

Der steuerbare Reflektor 113 ist hier auf einer Leiterplatte montiert, die weitere elektronische Bauteile zur Ansteuerung des steuerbaren Reflektors 113 oder mechanische Elemente umfassen kann.The controllable reflector 113 is mounted here on a printed circuit board, which can include other electronic components for controlling the controllable reflector 113 or mechanical elements.

Die Projektionsoptiken 102 und 202 umfassen jeweils zumindest eine optische Linse. Natürlich können auch Linsensysteme, die aus einer Anordnung mehrerer Linsen bestehen, oder auch zusätzlich Blenden umfassen, die Projektionsoptiken 102 und 202 bilden.The projection optics 102 and 202 each include at least one optical lens. Of course, lens systems that consist of an arrangement of multiple lenses or also additionally include screens that form projection optics 102 and 202.

Die erste Projektionsoptik 102 ist in einem Rahmen 103 befestigt, welcher in der Halterung 106 beweglich angeordnet ist. Ferner ist ein Hebel 107 umfasst. Der Rahmen 103 weist hier zwei Nasen 110 auf, die zwischen der Halterung 106 und dem Hebel 107 gelegen sind.The first projection optics 102 is fastened in a frame 103 which is movably arranged in the mount 106 . A lever 107 is also included. The frame 103 has here two lugs 110, which are located between the bracket 106 and the lever 107.

Die zweite Projektionsoptik 202 ist in einem Rahmen 203 befestigt, welcher in der Halterung 206 beweglich angeordnet ist. Ferner ist ein Hebel 207 mit zwei Drückelementen 211 umfasst. Der Rahmen 203 weist hier Nasen 210 auf, die zwischen der Halterung 206 und den Drückelementen 211 des Hebels 207 gelegen sind. Zwischen der Nase 210 und der Halterung 206 ist jeweils ein nachgiebiges, elastisches Federelement 209 angeordnet. Der Rahmen 203 wird mit einem Verbindungselement 212 an der Halterung 206 befestigt.The second projection optics 202 is fastened in a frame 203 which is movably arranged in the mount 206 . A lever 207 with two pressing elements 211 is also included. The frame 203 here has lugs 210 which are located between the bracket 206 and the pressing elements 211 of the lever 207 .
