Description

Die Erfindung betrifft ein Lichtmodul, wie es insbesondere in Kfz-Scheinwerfern Verwendung finden kann.The invention relates to a light module such as can be used in particular in motor vehicle headlights.

Unter einem Lichtmodul wird im vorliegenden Zusammenhang die eigentliche lichtaussendende Einheit eines Scheinwerfers verstanden, welche die gewünschte Abstrahllichtverteilung abgibt. Diese soll je nach Anwendungsgebiet bestimmte, in der Regel gesetzlich vorgegebene, charakteristische Intensitätsverläufe aufweisen. Mit KFZ-Scheinwerfern sollen beispielsweise abgeblendete Lichtverteilungen (Abblendlicht, Nebellicht) erzeugt werden, welche sich durch eine Hell-Dunkel-Grenze auszeichnen. Andererseits sollen Fernlicht-Lichtverteilungen erzeugt werden. Hierbei sind z.B. auch sogenannte Teil-Fernlicht-Verteilungen erwünscht, bei welchen gezielt bestimmte Bereiche der Abstrahllichtverteilung verdunkelt sind. Die erwünschten Abstrahllichtverteilung weisen daher meist eine gewisse Struktur aus hellen und dunklen Bereichen auf (z.B. eine Hell-Dunkel-Grenze oder einen ausgeblendeten Bereich), welche möglichst präzise und reproduzierbar erzielt werden soll.In the present context, a light module is understood to mean the actual light-emitting unit of a headlamp which emits the desired light distribution. Depending on the area of application, this should have certain, generally legally prescribed, characteristic intensity profiles. With vehicle headlights, for example, dimmed light distributions (dipped beam, fog light) are to be generated, which are characterized by a light-dark boundary. On the other hand, high beam light distributions are to be generated. Here are e.g. So-called partial high beam distributions are also desired, in which certain areas of the emitted light distribution are specifically darkened. The desired beam light distribution therefore usually has a certain structure of light and dark areas (e.g. a light-dark border or a masked area), which should be achieved as precisely and reproducibly as possible.

Zur Erzeugung der genannten Abstrahllichtverteilung sind verschiedenartige technische Lösungen bekannt. Die bekannten Lichtmodule umfassen meist eine Lichtquelle zum Ausstrahlen von Licht, eine Primäroptik zum Formen einer gewünschten Zwischenlichtverteilung aus dem Licht der Lichtquelle, sowie eine Sekundäroptik, welche dazu eingerichtet ist, die von der Primäroptik erzeugte Zwischenlichtverteilung als Abstrahllichtverteilung in das Vorfeld des Lichtmoduls zu projizieren. Insbesondere sind Lichtmodule bekannt, welche eine Linseneinrichtung aufweisen, die zur Formung einer gewünschten Lichtverteilung eingerichtet ist.Various technical solutions are known for generating the said emitted light distribution. The known light modules usually include a light source for emitting light, primary optics for shaping a desired intermediate light distribution from the light from the light source, as well as secondary optics which are set up to project the intermediate light distribution generated by the primary optics as an emitted light distribution into the area in front of the light module. In particular are Light modules are known which have a lens device which is set up to shape a desired light distribution.

Damit die mit solchen Lichtmodulen erzeugte Abstrahllichtverteilung die gewünschten Eigenschaften hat, ist eine genaue Positionierung der optisch funktionalen Bauteile zueinander von entscheidender Bedeutung.Precise positioning of the optically functional components with respect to one another is of decisive importance so that the light distribution generated with such light modules has the desired properties.

So hat beispielsweise die Anordnung der Primäroptik relativ zur Lichtquelle Einfluss auf den Anteil des Lichts der Lichtquelle, welcher von der Primäroptik erfasst wird und bestimmt daher die Effizienz des Lichtmoduls.For example, the arrangement of the primary optics relative to the light source has an influence on the portion of the light from the light source that is captured by the primary optics and therefore determines the efficiency of the light module.

Die Anordnung der Sekundäroptik relativ zur Primäroptik und/oder zur Lichtquelle hat Einfluss darauf, ob gewünschte Hell-Dunkel-Übergänge mit ausreichendem Kontrast abgebildet werden.The arrangement of the secondary optics relative to the primary optics and / or the light source influences whether the desired light-dark transitions are reproduced with sufficient contrast.

Ein weiteres Problem ist darin begründet, dass Linsen oder andere transparente optischen Elemente in der Regel aus einem lichtbrechenden Material gefertigt sind. Solche Materialien weisen meist Dispersionseigenschaften auf, d.h. sie zeigen eine Abhängigkeit des Brechungsindex von der Wellenlänge des Lichts. In der Regel tritt für Licht im blauen Wellenlängenspektrum eine stärkere Brechung auf, als für Licht im roten Wellenlängenspektrum. Bei Verwendung von Linsen in Lichtmodulen kann dies dazu führen, dass die Abstrahllichtverteilung unerwünschte Farbeffekte zeigt. Die angesprochenen Strukturen der Abstrahllichtverteilung aus hellen und dunklen Bereichen (z.B. Hell-Dunkel-Grenze des Abblendlichts, ausgeblendete Bereiche des Teilfernlichts) können Farbränder oder Farbsäume zeigen. Dieser Dispersionseffekt macht sich besonders ausgeprägt bei Linseneinrichtungen bemerkbar, welche zur Projektion oder zur Abbildung einer (beispielsweise durch eine Primäroptik erzeugten) Zwischenlichtverteilung als Abstrahllichtverteilung in das Vorfeld des Lichtmoduls dienen, d.h. bei einer als Sekundäroptik wirkenden Linseneinrichtung. Um die unerwünschten Farbeffekte möglichst gering zu halten, sollen die genannten Linseneinrichtung (z.B. Sekundäroptik) präzise in Bezug auf andere optisch-funktionale Einrichtungen (z.B. Primäroptik) ausgerichtet und befestigt werden.Another problem is that lenses or other transparent optical elements are usually made of a light-refractive material. Such materials mostly have dispersion properties, ie they show a dependence of the refractive index on the wavelength of the light. As a rule, there is stronger refraction for light in the blue wavelength spectrum than for light in the red wavelength spectrum. When using lenses in light modules, this can lead to the emission of light distribution showing undesirable color effects. The mentioned structures of the emitted light distribution from light and dark areas (for example light-dark border of the low beam, masked areas of the partial high beam) can show colored edges or color fringes. This dispersion effect is particularly noticeable in lens devices which are used for projection or for imaging (for example through primary optics generated) intermediate light distribution serve as emission light distribution in the area in front of the light module, ie with a lens device acting as a secondary optics. In order to keep the undesired color effects as low as possible, the lens devices mentioned (for example secondary optics) should be precisely aligned and fixed in relation to other optical-functional devices (for example primary optics).

Um dies zu erreichen, wird im Stand der Technik die Linseneinrichtung meist in einem Linsenhalter gehaltert, welcher durch Verschrauben, Verklemmen oder Umformen des Linsenhalters im Lichtmodul festgesetzt wird. Ein Problem besteht dann darin, dass ein Lösen der Befestigung problematisch sein kann oder dass nach einem Lösen der Befestigung eine erneute Befestigung nur noch mit geringerer Positionsgenauigkeit möglich ist (z.B. da Schraubbuchsen oder Gewinde durch wiederholtes Ein- und Ausschrauben ausgeweitet sind).In order to achieve this, in the prior art the lens device is mostly held in a lens holder which is fixed in the light module by screwing, clamping or reshaping the lens holder. One problem then is that loosening the fastening can be problematic or that after loosening the fastening, renewed fastening is only possible with less positional accuracy (e.g. because screw sockets or threads are expanded by repeated screwing in and unscrewing).

Eine genaue Positionierung und Befestigung ist insbesondere problematisch, wenn Kunststoffteile verwendet werden sollen, da diese weicher als Metalle sind und z.B. in Gewinden oder Schraubbuchsen Verformungen auftreten können. Dennoch ist die Verwendung von Kunststoffteilen zunehmend erwünscht, da solche Bauteile vergleichsweise einfach und kostengünstig hergestellt werden können (z.B. im Spritzgussverfahren). Außerdem können Kunststoffteile als Designteile ausgebildet werden, was insbesondere für von außerhalb des Lichtmoduls sichtbare Linseneinrichtungen und Linsenhalter erwünscht ist.Accurate positioning and fastening is particularly problematic when plastic parts are to be used, since these are softer than metals and e.g. Deformations can occur in threads or screw sockets. Nevertheless, the use of plastic parts is increasingly desirable, since such components can be produced comparatively easily and inexpensively (e.g. by injection molding). In addition, plastic parts can be designed as design parts, which is particularly desirable for lens devices and lens holders that are visible from outside the light module.

In der EP 2 428 725 A2 ist eine Beleuchtungseinheit mit den Merkmalen des Oberbegriffs des Anspruchs 1 beschrieben.In the EP 2 428 725 A2 a lighting unit with the features of the preamble of claim 1 is described.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Lichtmodul eine präzise positionierbare und gleichzeitig auf einfache Weise lösbare Befestigung der Linseneinrichtung relativ zu anderen optischen Bauteilen zu ermöglichen. Dies soll insbesondere bei Kunststoffteilen vorteilhaftmöglich sein.The invention is based on the object at a Light module to enable a precisely positionable and at the same time easily detachable fastening of the lens device relative to other optical components. This should be particularly advantageous in the case of plastic parts.

Diese Aufgabe wird durch ein Lichtmodul gemäß dem Anspruch 1 gelöst. Hierbei handelt es sich um ein Lichtmodul, insbesondere für Kfz-Scheinwerfer, welches dazu eingerichtet ist, Licht mit einer Abstrahllichtverteilung in eine Hauptabstrahlrichtung des Lichtmoduls abzustrahlen. Das Lichtmodul weist eine Linseneinrichtung, beispielsweise Sammellinse, zum Formen einer gewünschten Lichtverteilung auf. Bei dieser Lichtverteilung kann es sich um die endgültige Abstrahllichtverteilung des Lichtmoduls oder um eine Zwischenlichtverteilung handeln. Die Linseneinrichtung ist mittels einer Positionierungseinrichtung in eine gewünschte Position an dem Lichtmodul positionsgenau geführt und mittels einer Befestigungseinrichtung dort befestigt. Die Führung ist positionsgenau insofern, als das die räumliche Position der Linseneinrichtung relativ zu anderen Bauteilen des Lichtmoduls bezüglich aller drei Raumrichtungen präzise festgelegt werden kann. Die Befestigungseinrichtung dient dazu, die Linseneinrichtung in der mittels der Positionierungseinrichtung vorgegebenen Position mit einem oder mehreren übrigen Bauteilen des Lichtmoduls zu verbinden.This object is achieved by a light module according to claim 1. This is a light module, in particular for motor vehicle headlights, which is set up to emit light with an emitted light distribution in a main emission direction of the light module. The light module has a lens device, for example a collecting lens, for shaping a desired light distribution. This light distribution can be the final emission light distribution of the light module or an intermediate light distribution. The lens device is guided into a desired position on the light module with precise positioning by means of a positioning device and is fastened there by means of a fastening device. The guidance is positionally accurate insofar as the spatial position of the lens device relative to other components of the light module can be precisely determined with respect to all three spatial directions. The fastening device serves to connect the lens device to one or more other components of the light module in the position specified by the positioning device.

Bei dem erfindungsgemäßen Lichtmodul weist die Positionierungseinrichtung wenigstens einen Passstift und eine zugeordnete Passbuchse auf, wobei der Passstift zur Positionierung der Linseneinrichtung in die Passbuchse eingreift. Die Befestigungseinrichtung weist wenigstens einen von dem Passstift verschieden ausgebildeten Befestigungsvorsprung, eine zugeordnete Befestigungsausnehmung, welche von der Passbuchse verschieden ausgebildet ist, sowie ein zugeordnetes Befestigungsmittel auf. Dabei greift zur Befestigung der Linseneinrichtung der Befestigungsvorsprung in die Befestigungsausnehmung ein und wird mit dem Befestigungsmittel fixiert.In the light module according to the invention, the positioning device has at least one dowel pin and an associated dowel socket, the dowel pin engaging in the dowel socket for positioning the lens device. The fastening device has at least one fastening projection which is designed differently from the dowel pin, an associated fastening recess which is from the dowel socket is designed differently, as well as an associated fastening means. To fasten the lens device, the fastening projection engages in the fastening recess and is fixed with the fastening means.

Die Positionierungseinrichtung dient dazu, eine axiale Justage der Linseneinrichtung im Lichtmodul zu ermöglichen. Der Passstift erstreckt sich entlang einer Führungsrichtung und ist entlang dieser Führungsrichtung in der Passbuchse spielfrei verschiebbar. Dies ermöglicht eine präzise Einstellung des Abstandes der Linseneinrichtung zu anderen optisch funktionalen Bauteilen des Lichtmoduls. Dabei wird jedoch eine seitliche Positionierungsungenauigkeit vermieden. Die Führung ist spielfrei insofern, als dass eine gewünschte Passungsqualität erreicht wird, beispielsweise das die Teile gegeneinander ohne merkliches Spiel beweglich sind, wie dies für Zahnräder oder Kupplungen üblich ist. Denkbar ist auch eine Passung derart, dass Teile gegeneinander von Hand gerade noch verschiebbar ist, wie dies für Führungen an Werkzeugmaschinen oder Stellringen üblich ist.
Die Führungsrichtung ist im Wesentlichen parallel zur Hauptabstrahlrichtung des Lichtmoduls gewählt, so dass durch axiale Verlagerung der Linseneinrichtung keine seitliche Positionierungsungenauigkeit hervorgerufen wird.The positioning device serves to enable an axial adjustment of the lens device in the light module. The dowel pin extends along a guide direction and can be displaced without play along this guide direction in the dowel bush. This enables a precise setting of the distance between the lens device and other optically functional components of the light module. However, a lateral positioning inaccuracy is avoided. The guide is backlash-free insofar as a desired quality of fit is achieved, for example that the parts can be moved relative to one another without noticeable play, as is customary for gearwheels or clutches. A fit is also conceivable such that parts can just barely be moved against one another by hand, as is usual for guides on machine tools or adjusting rings.
The guide direction is selected to be essentially parallel to the main emission direction of the light module, so that no lateral positioning inaccuracy is caused by the axial displacement of the lens device.

Der Befestigungsvorsprung ist vorzugsweise ebenfalls stiftartig ausgebildet. Entsprechend kann die Befestigungsausnehmung in der Art einer Buchse ausgebildet sein.The fastening projection is preferably also designed like a pin. Correspondingly, the fastening recess can be designed in the manner of a socket.

Der Erfindung liegt die Idee zugrunde, eine funktionale Auftrennung zwischen Positionierung und Befestigung zu erzielen. Die Positionierungseinrichtung ist hochpräzise geformt. Hierbei greift der Passstift im Wesentlichen spielfrei in die Passbuchse ein. Passstift und Passbuchse weisen eine hochgenaue Passung auf, vorzugsweise so, dass die Teile gerade noch von Hand gegeneinander verschiebbar sind. Bei der Befestigungseinrichtung hingegen können geringere Anforderungen an die Passung gestellt werden. Entscheidend ist hier, dass eine Befestigung möglich ist, welche insbesondere auch lösbar ausgestaltet ist. Selbst wenn die Befestigungseinrichtung durch mehrfaches Lösen und wieder Befestigen an Passgenauigkeit verliert (beispielsweise durch Aufweiten von Gewinden), so wird die positionsgenaue Ausrichtung durch die Positionierungseinrichtung gewährleistet.The invention is based on the idea of achieving a functional separation between positioning and fastening. The positioning device is shaped with high precision. The alignment pin essentially engages here backlash-free into the fitting socket. Dowel pin and dowel bush have a highly precise fit, preferably in such a way that the parts can just about be moved against one another by hand. In the case of the fastening device, however, lower demands can be placed on the fit. The decisive factor here is that a fastening is possible, which in particular is also designed to be detachable. Even if the fastening device loses its accuracy of fit as a result of multiple loosening and re-fastening (for example, by widening threads), the positioning device ensures the exact positioning.

Die erfindungsgemäße Ausgestaltung erlaubt eine passgenaue Anordnung insbesondere auch dann, wenn wesentliche Bauteile des Lichtmoduls aus Kunststoff ausgebildet sind. Dies ist oftmals erwünscht, da dadurch die Teile besonders günstig herstellbar sind und als Designteil ausgebildet sein können. Vorzugsweise sind Teile der Linseneinrichtung, beispielsweise ein Linsenhalter der Linseneinrichtung, insbesondere Befestigungsvorsprung und/oder Befestigungsausnehmung und/oder die Befestigungsmittel aus Kunststoff ausgebildet. Hierbei wird vorzugsweise ein zum Spritzgussverfahren geeigneter Kunststoff verwendet, beispielsweise PMMA, Polycarbonat, Polyimide oder Ähnliches. Auch bei solchen Kunststoffteilen ist mit der erfindungsgemäßen Lösung ein mehrfaches Befestigen und Lösen der Linseneinrichtung möglich. Selbst wenn die Befestigungseinrichtung durch Verformung der Passteile an Präzision verliert (zum Beispiel durch charakteristische Kriechprozesse von Kunststoffmaterial unter Druck in Gewinden), so wird eine genaue Positionierung durch die Positionierungseinrichtung gewährleistet.The configuration according to the invention allows a precisely fitting arrangement, especially when essential components of the light module are made of plastic. This is often desirable because it enables the parts to be manufactured particularly cheaply and to be designed as a design part. Parts of the lens device, for example a lens holder of the lens device, in particular a fastening projection and / or fastening recess and / or the fastening means are preferably formed from plastic. A plastic suitable for the injection molding process is preferably used here, for example PMMA, polycarbonate, polyimide or the like. In the case of such plastic parts, too, the solution according to the invention enables multiple fastening and loosening of the lens device. Even if the fastening device loses precision due to deformation of the fitting parts (for example due to characteristic creeping processes of plastic material under pressure in threads), precise positioning is ensured by the positioning device.

Das Lichtmodul umfasst in der Regel weitere Bauteile, wie eingangs zu den bekannten Lichtmodulen erläutert.The light module usually includes further components, as explained at the beginning of the known light modules.

Insbesondere ist eine Lichtquelle zum Ausstrahlen von Licht vorgesehen, wobei die Linseneinrichtung dazu eingerichtet ist, das von der Lichtquelle ausgestrahlte Licht direkt oder indirekt (d.h. über eine weitere optische Einrichtung) in eine gewünschte Lichtverteilung zu formen, beispielsweise zu bündeln oder zu kollimieren. Insbesondere kann das Lichtmodul auch eine Primäroptik zum Formen einer gewünschten Zwischenlichtverteilung aus dem Licht der Lichtquelle aufweisen. Dann ist in der Regel eine Sekundäroptik vorgesehen, welche dazu eingerichtet ist, die von der Primäroptik erzeugte Lichtverteilung als Abstrahllichtverteilung in das Vorfeld des Lichtmoduls zu projizieren oder abzubilden. In diesem Fall bildet die genannte Linseneinrichtung insbesondere die Sekundäroptik.In particular, a light source for emitting light is provided, the lens device being set up to shape the light emitted by the light source directly or indirectly (i.e. via a further optical device) into a desired light distribution, for example to focus or collimate it. In particular, the light module can also have primary optics for forming a desired intermediate light distribution from the light from the light source. As a rule, secondary optics are then provided, which are set up to project or map the light distribution generated by the primary optics as an emitted light distribution into the area in front of the light module. In this case, the lens device mentioned forms the secondary optics in particular.

Vorzugsweise sind der Passstift und der Befestigungsvorsprung an der Linseneinrichtung unmittelbar oder mittelbar (d.h. über ein weiteres Bauteil, z.B. Träger) angeordnet. Die Passbuchse und die Befestigungsausnehmung können dann an einem sonstigen Abschnitt des Lichtmoduls angeordnet sein, beispielsweise an einer Lichtquelleneinrichtung, einem Trägerelement oder einer Primäroptikeinrichtung, bezüglich welcher die Linseneinrichtung positioniert und befestigt werden soll.The dowel pin and the fastening projection are preferably arranged directly or indirectly (i.e. via a further component, e.g. carrier) on the lens device. The fitting socket and the fastening recess can then be arranged on another section of the light module, for example on a light source device, a carrier element or a primary optics device with respect to which the lens device is to be positioned and fastened.

Denkbar ist jedoch auch eine andere Aufteilung der Bestandteile von Befestigungseinrichtung und Positionierungseinrichtung. So kann beispielsweise die Passbuchse an der Linseneinrichtung und der zugeordnete Passstift an einem sonstigen Bauteil des Lichtmoduls angeordnet sein. Ebenso kann die Befestigungsausnehmung an der Linseneinrichtung und der zugeordnete Befestigungsvorsprung an einem übrigen Bauteil des Lichtmoduls angeordnet sein. Denkbar ist auch, dass die Linseneinrichtung den Passstift und die Befestigungsausnehmung aufweist, wogegen Passbuchse und Befestigungsvorsprung an einem sonstigen Bauteil des Lichtmoduls vorgesehen sind.However, a different division of the components of the fastening device and the positioning device is also conceivable. For example, the fitting socket can be arranged on the lens device and the associated dowel pin can be arranged on another component of the light module. Likewise, the fastening recess can be arranged on the lens device and the associated fastening projection can be arranged on another component of the light module. It is also conceivable that the lens device has the alignment pin and the fastening recess, whereas the alignment socket and Fastening projection are provided on another component of the light module.

Zur Erhöhung der Positionsgenauigkeit kann die Passbuchse als Sinterbuchse ausgebildet sein. Insbesondere ist die Passbuchse aus einem metallischen Sinterwerkstoff ausgebildet. Diese Sinterbuchse kann beispielsweise in ein Kunststoffbauteil eingegossen sein.To increase the positional accuracy, the fitting bushing can be designed as a sintered bushing. In particular, the fitting bushing is made from a metallic sintered material. This sintered bush can for example be cast into a plastic component.

Der Passstift kann als gedrehter Metallstift ausgebildet sein. Auch dadurch wird die Positionsgenauigkeit verbessert, da mit Metallteilen genauere Passungen als mit Kunststoffteilen erzielt werden können. Der gedrehte Metallstift kann beispielsweise in ein Kunststoffteil eingegossen sein. Hierzu kann dieses Kunststoffteil nach einem ersten Herstellungsschritt eine Stiftausnehmung aufweisen, in welche der Metallstift in einem zweiten Herstellungsschritt eingegossen wird.The dowel pin can be designed as a turned metal pin. This also improves the positional accuracy, since more precise fits can be achieved with metal parts than with plastic parts. The rotated metal pin can for example be cast into a plastic part. For this purpose, after a first manufacturing step, this plastic part can have a pin recess into which the metal pin is cast in a second manufacturing step.

Der Befestigungsvorsprung ist vorzugsweise als ein sich entlang einer Verbindungsrichtung erstreckender Stift ausgebildet. Insbesondere weist dieser Stift einen sich entlang der Verbindungsrichtung erstreckenden Fixierschlitz auf, in welche das zugeordnete Befestigungsmittel eingreifen kann. Das zugeordnete Befestigungsmittel ist insbesondere als Fixierschraube ausgebildet, welche in den Fixierschlitz des Stiftes eingedreht werden kann. Vorzugsweise wird die Fixierschraube in einer Richtung senkrecht zu der Verbindungsrichtung in den Fixierschlitz derart eingedreht, dass der stiftartige Befestigungsvorsprung in der Befestigungsausnehmung fixiert ist. Die Befestigungsausnehmung ist hierzu insbesondere in der Art einer Buchse ausgebildet, in welcher der Befestigungsvorsprung entlang der genannten Verbindungsrichtung verschiebbar ist, wobei die Befestigungsausnehmung ein senkrecht zur Verbindungsrichtung verlaufendes Schraubloch aufweist, durch welches die Fixierschraube in den Fixierschlitz eingedreht werden kann. Da sich der Fixierschlitz entlang der Verbindungsrichtung erstreckt, kann der Befestigungsvorsprung in eine gewünschte Tiefe in die Befestigungsausnehmung eingeschoben werden und durch Eindrehen der Fixierschraube befestigt werden. Insbesondere ist der stiftartige Befestigungsvorsprung derart geschlitzt ausgebildet, dass sich der Stift durch Eindrehen der Fixierschraube in den Fixierschlitz aufspreizt. Dadurch kann eine abschnittsweise formschlüssige Verbindung zwischen dem Befestigungsvorsprung und der Befestigungsausnehmung hergestellt werden. Diese Ausgestaltung ist insbesondere bei Kunststoffbauteilen vorteilhaft, da bei derartigen Materialien bei Kraftbelastung typische Verformungen durch Kriechprozesse im Material auftreten können.The fastening projection is preferably designed as a pin extending along a connecting direction. In particular, this pin has a fixing slot which extends along the connection direction and into which the associated fastening means can engage. The associated fastening means is designed in particular as a fixing screw which can be screwed into the fixing slot of the pin. The fixing screw is preferably screwed into the fixing slot in a direction perpendicular to the connection direction in such a way that the pin-like fastening projection is fixed in the fastening recess. For this purpose, the fastening recess is designed in particular in the manner of a socket in which the fastening projection can be displaced along the connecting direction mentioned, the fastening recess having a screw hole running perpendicular to the connection direction through which the fixing screw can be screwed into the fixing slot. Since the fixing slot extends along the connection direction, the fastening projection can be pushed into the fastening recess to a desired depth and can be fastened by screwing in the fixing screw. In particular the pin-like fastening projection is designed to be slotted in such a way that the pin spreads open by screwing the fixing screw into the fixing slot. As a result, a form-fitting connection can be established in sections between the fastening projection and the fastening recess. This configuration is particularly advantageous in the case of plastic components, since with such materials typical deformations due to creep processes can occur in the material under force loading.

Zur weiteren Ausgestaltung weist die Linseneinrichtung einen Linsenhalter auf, in welchem ein optisch wirksames Linsenelement (beispielsweise Sammellinse) gehaltert ist. An dem Linsenhalter sind vorzugsweise Bestandteile der Befestigungseinrichtung und der Positionierungseinrichtung angeordnet. Insbesondere ist der Passstift und/oder der Befestigungsvorsprung an dem Linsenhalter vorgesehen. Selbstverständlich kann an dem Linsenhalter auch die Passbuchse und/oder die Befestigungsausnehmung angeordnet sein.For a further refinement, the lens device has a lens holder in which an optically effective lens element (for example, a converging lens) is held. Components of the fastening device and the positioning device are preferably arranged on the lens holder. In particular, the dowel pin and / or the fastening projection is provided on the lens holder. Of course, the fitting bushing and / or the fastening recess can also be arranged on the lens holder.

Das Lichtmodul kann außerdem einen Halterahmen aufweisen, über welchen die Linseneinrichtung im Lichtmodul fixiert wird. Hierzu weist der dem Linsenelement abgewandte Abschnitt des Linsenhalters einen Verbindungsabschnitt auf, welcher mit einem entsprechenden Verbindungsabschnitt des Halterahmens zusammengefügt werden kann. An den Verbindungsabschnitten von Halterahmen und Linsenhalter sind Passstift, Passbuchse beziehungsweise Befestigungsvorsprung, Befestigungsausnehmung angeordnet.The light module can also have a holding frame, via which the lens device is fixed in the light module. For this purpose, the section of the lens holder facing away from the lens element has a connecting section which can be joined to a corresponding connecting section of the holding frame. Dowel pin, dowel socket or fastening projection and fastening recess are arranged on the connecting sections of the holding frame and lens holder.

Vorzugsweise erstrecken sich Führungsstift und Befestigungsvorsprung parallel zueinander. Insofern verlaufen die genannte Führungsrichtung und die genannte Verbindungsrichtung im Wesentlichen parallel. Dadurch wird eine axiale Justage und positionsgenaue axiale Befestigung der Linseneinrichtung ermöglicht.The guide pin and the fastening projection preferably extend parallel to one another. To that extent said guiding direction and said connecting direction run essentially parallel. This enables an axial adjustment and positionally accurate axial fastening of the lens device.

Nach einem weiteren Aspekt der Erfindung greift der Passstift befestigungsfrei in die Passbuchse ein. Dann sind Positionierungseinrichtung und Befestigungseinrichtung funktional voneinander vollständig getrennt. Die Positionierungsfunktion wird auch durch mehrfaches Befestigen und Lösen der Befestigungseinrichtung nicht beeinträchtigt.According to a further aspect of the invention, the dowel pin engages in the dowel socket without fastening. The positioning device and the fastening device are then functionally completely separated from one another. The positioning function is not impaired by multiple fastening and loosening of the fastening device.

In der folgenden Beschreibung werden für einander entsprechende Bauteile und Merkmale jeweils dieselben Bezugszeichen verwendet.In the following description, the same reference numerals are used for corresponding components and features.

Figur 1 zeigt ein modular aufgebautes Lichtmodul 10, welches aus vormontierten Baueinheiten aufgebaut ist. Die Hauptkomponenten des Lichtmoduls 10 sind: Eine Lichtquelleneinheit 12, eine Primäroptikeinheit 14, ein Halterahmen 16 sowie eine Sekundäroptikeinheit 18, welche eine Linseneinrichtung im vorliegenden Sinne bildet. Diese Baueinheiten sind in der Darstellung gemäß Figur 1 entlang einer Montagerichtung 20 aufgereiht abgebildet und werden zur Endmontage des Lichtmoduls 10 im Wesentlichen entlang der Montagerichtung 20 aufeinander zu bewegt und zusammengefügt. Figure 1 shows a modular light module 10, which is made up of pre-assembled units. The main components of the light module 10 are: a light source unit 12, a primary optics unit 14, a holding frame 16 and a secondary optics unit 18, which forms a lens device in the present sense. These structural units are shown in accordance with Figure 1 Imaged lined up along an assembly direction 20 and for the final assembly of the light module 10 they are moved towards one another essentially along the assembly direction 20 and assembled.

Die Lichtquelleneinheit 12 umfasst eine Leiterplatine 22, welche eine der Primäroptikeinheit 14 zugewandte Frontseite der Lichtquelleneinheit 12 bildet. Auf der Leiterplatine 22 sind eine Mehrzahl von Halbleiterlichtquellen 26 zum Ausstrahlen von Licht gruppiert in der Art einer Matrix angeordnet. Ferner sind auf der Leiterplatine 22 elektrische Bauteile einer Steuereinrichtung angeordnet, mittels welcher die einzelnen Halbleiterlichtquellen zur Lichtabgabe ansteuerbar sind.The light source unit 12 comprises a printed circuit board 22, which forms a front side of the light source unit 12 facing the primary optics unit 14. On the circuit board 22, a plurality of semiconductor light sources 26 for emitting light are arranged grouped in the manner of a matrix. Furthermore, electrical components of a control device are arranged on the printed circuit board 22, by means of which the individual semiconductor light sources can be controlled for light output.

Die Primäroptikeinheit 14 weist ein Primäroptikelement 32 auf, welches eine Primäroptikaustrittsfläche 36 aufweist. Das Primäroptikelement 32 weist außerdem eine Mehrzahl von Lichteintrittsflächen auf (in Fig. 1 nicht dargestellt), durch welche Licht in das Primäroptikelement 32 eingekoppelt werden kann. Das eingekoppelte Licht wird in dem Primäroptikelement 32 gebündelt oder kollimiert und tritt durch die Primäroptikaustrittsfläche 36 aus und bildet dort eine Zwischenlichtverteilung.The primary optics unit 14 has a primary optics element 32 which has a primary optics exit surface 36. The primary optics element 32 also has a plurality of light entry surfaces (in Fig. 1 not shown), through which light can be coupled into the primary optics element 32. The coupled light is in bundled or collimated by the primary optics element 32 and exits through the primary optics exit surface 36 and forms an intermediate light distribution there.

Die Sekundäroptikeinheit 18 umfasst ein als Sammellinse ausgebildetes Linsenelement 48. Dieses ist dazu ausgebildet, im Betrieb des Lichtmoduls 10 die sich auf der Primäroptikaustrittsfläche 36 einstellende Zwischenlichtverteilung in die Abstrahllichtverteilung in das Vorfeld des Lichtmoduls 10 zu projizieren. Die Sekundäroptikeinheit 18 bildet daher eine Linseneinrichtung im vorliegenden Sinne. Die erfindungsgemäße Idee kann jedoch auch für die Befestigung anderer Linseneinrichtungen eines Lichtmoduls Anwendung finden, welche keine Sekundäroptik bilden.The secondary optics unit 18 comprises a lens element 48 designed as a converging lens. This is designed to project the intermediate light distribution occurring on the primary optics exit surface 36 into the light distribution in the area in front of the light module 10 during operation of the light module 10. The secondary optics unit 18 therefore forms a lens device in the present sense. However, the idea according to the invention can also be used for fastening other lens devices of a light module which do not form secondary optics.

Die Sekundäroptikeinheit 18 umfasst einen Linsenhalter 50, welcher einerseits zum Halten des Linsenelements 48 dient, andererseits zu einer positionsgenauen Ausrichtung der Sekundäroptikeinheit 18 beiträgt. Hierzu weist der der Linseneinrichtung 48 abgewandte Bereich des Linsenhalters 50 einen Verbindungsabschnitt 52 auf. Die Sekundäroptikeinheit 18 weist außerdem ein Zierelement 54 auf, welches rahmenartig ausgebildet ist und derart an dem Linsenhalter 50 angeordnet ist, dass es das Linsenelement 48 rahmenartig umfasst. Das Zierelement 54 ist derart ausgebildet und angeordnet, dass es im zusammengebauten Zustand des Lichtmoduls 10 bei Blick auf die Sekundäroptikeinheit 18 sichtbar ist und somit das Design bestimmt. Das Zierelement 54 ist zumindest auch teilweise sichtbar, wenn das Lichtmodul 10 in einem Scheinwerfer verbaut ist.The secondary optics unit 18 comprises a lens holder 50 which, on the one hand, serves to hold the lens element 48 and, on the other hand, contributes to a positionally accurate alignment of the secondary optics unit 18. For this purpose, the region of the lens holder 50 facing away from the lens device 48 has a connecting section 52. The secondary optics unit 18 also has a decorative element 54 which is designed like a frame and is arranged on the lens holder 50 in such a way that it surrounds the lens element 48 like a frame. The decorative element 54 is designed and arranged in such a way that, in the assembled state of the light module 10, it is visible when looking at the secondary optics unit 18 and thus determines the design. The decorative element 54 is also at least partially visible when the light module 10 is installed in a headlight.

Zur Montage des Lichtmoduls 10 wird der Halterahmen 16 zwischen der Primäroptikeinheit 14 einerseits und der Sekundäroptikeinheit 18 andererseits angeordnet. Der Halterahmen 16 weist in seinem der Sekundäroptikeinheit 18 zugewandten Bereich einen Verbindungsabschnitt 56 auf. Dieser kann mit dem Verbindungsabschnitt 52 des Linsenhalters 50 zusammengefügt werden.To mount the light module 10, the holding frame 16 arranged between the primary optics unit 14 on the one hand and the secondary optics unit 18 on the other hand. The holding frame 16 has a connecting section 56 in its area facing the secondary optics unit 18. This can be joined together with the connecting section 52 of the lens holder 50.

Wesentliche Bestandteile des Lichtmoduls 10 sind zumindest im Wesentlichen aus Kunststoff hergestellt. Dies gilt insbesondere für den Linsenhalter 50, das Zierelement 54 und den Halterahmen 16. Diese Teile können in vorteilhafter Weise im Spritzgussverfahren hergestellt sein. Auch die Linseneinrichtung 48 bzw. einzelne Linsen der Linseneinrichtung 48 bestehen bevorzugt aus Kunststoff. Kunststofflinsen eröffnen große gestalterische Möglichkeiten.Essential components of the light module 10 are made at least essentially from plastic. This applies in particular to the lens holder 50, the decorative element 54 and the holding frame 16. These parts can advantageously be manufactured by injection molding. The lens device 48 or individual lenses of the lens device 48 are also preferably made of plastic. Plastic lenses open up great design possibilities.

Bei der Endmontage des Lichtmoduls 10 wird die Linseneinrichtung 18 mit dem Halterahmen 16 und damit mit den übrigen Bauteilen des Lichtmoduls 10 verbunden. Dazu ist zum einen eine Positionierungseinrichtung 60 vorgesehen, welche dazu eingerichtet ist, die Linseneinrichtung 18 in eine gewünschte räumliche Position positionsgenau zu führen. Andererseits ist eine Befestigungseinrichtung 80 zum Befestigen der Linseneinrichtung 18 in der gewünschten Position vorgesehen.During the final assembly of the light module 10, the lens device 18 is connected to the holding frame 16 and thus to the other components of the light module 10. For this purpose, a positioning device 60 is provided on the one hand, which is set up to guide the lens device 18 into a desired spatial position with precise positioning. On the other hand, a fastening device 80 is provided for fastening the lens device 18 in the desired position.

Die Positionierungseinrichtung 60 und die Befestigungseinrichtung 80 werden zunächst anhand der Figuren 2 und 3 erläutert, welche die Sekundäroptikeinheit 18 (Fig. 2) und den Halterahmen 16 (Fig. 3) des Lichtmoduls 10 in Detailansicht zeigen.The positioning device 60 and the fastening device 80 are initially based on Figures 2 and 3 explains which the secondary optics unit 18 ( Fig. 2 ) and the holding frame 16 ( Fig. 3 ) of the light module 10 show in detail.

Der Linsenhalter 50 weist an seinem Verbindungsabschnitt 52 zwei Passstifte 62 auf (vergleiche Figur 2). Jeder Passstift 62 ist als gedrehter Metallstift ausgebildet, welcher in das Kunststoffmaterial des Linsenhalters 50 eingegossen ist.The lens holder 50 has two dowel pins 62 on its connecting section 52 (cf. Figure 2 ). Each dowel pin 62 is designed as a turned metal pin which is cast into the plastic material of the lens holder 50.

Der Halterahmen 16 weist an seinem Verbindungsabschnitt 56 zwei den Passstiften 62 zugeordnete Passbuchsen 64 auf (vergleiche Figur 3). Die Passbuchsen 64 sind als Sinterbuchsen aus einem metallischen Sintermaterial ausgebildet und in das Kunststoffmaterial des Halterahmens 16 eingegossen.On its connecting section 56, the holding frame 16 has two locating sockets 64 assigned to the locating pins 62 (cf. Figure 3 ). The fitting sockets 64 are designed as sintered sockets made of a metallic sintered material and cast into the plastic material of the holding frame 16.

Jeder Passstift 62 erstreckt sich stiftartig entlang einer Führungsrichtung 66, entlang welcher der Passstift 62 in die jeweils zugeordnete Passbuchse 64 einschiebbar ist.Each dowel pin 62 extends like a pin along a guide direction 66, along which the dowel pin 62 can be inserted into the respectively assigned fitting bushing 64.

Die Positionierungseinrichtung 60 umfasst die Passstifte 62 und die jeweils zugeordneten Passbuchsen 64. Diese ermöglichen es, die Linseneinrichtung 18 in eine gewünschte räumliche Position relativ zu den übrigen Bauteilen des Lichtmoduls 10 zu führen.The positioning device 60 comprises the dowel pins 62 and the respectively assigned dowel bushings 64. These allow the lens device 18 to be guided into a desired spatial position relative to the other components of the light module 10.

Bei dem Lichtmodul 10 ist außerdem eine Befestigungseinrichtung vorgesehen, welche dazu dient, die Linseneinrichtung 18 in der durch die Positionierungseinrichtung 60 vorgegebenen Position zu fixieren.In the light module 10, a fastening device is also provided which serves to fix the lens device 18 in the position specified by the positioning device 60.

Die Befestigungseinrichtung 80 umfasst zum einen Befestigungsvorsprünge 82 am Verbindungsabschnitt 52 des Linsenhalters 50.The fastening device 80 comprises, on the one hand, fastening projections 82 on the connecting section 52 of the lens holder 50.

Ferner umfasst die Befestigungseinrichtung 80 am Halterahmen 16 Befestigungsausnehmungen 84, welche den Befestigungsvorsprüngen 82 jeweils zugeordnet sind. Die Befestigungsvorsprünge 82 und die Befestigungsausnehmungen 84 sind in dem Kunststoffmaterial des Linsenhalters 50 beziehungsweise des Halterahmens 16 ausgeformt. Vorzugsweise werden die Befestigungsvorsprünge 82 bei der Herstellung des Linsenhalters 50 beispielsweise im Spritzgießverfahren einstückig mit geformt. Die Befestigungsausnehmungen 84 können bei der Herstellung des Halterahmens 16 in diesem einstückig ausgebildet werden, beispielsweise im Spritzgussverfahren.Furthermore, the fastening device 80 comprises on Holding frame 16, fastening recesses 84 which are assigned to the fastening projections 82 in each case. The fastening projections 82 and the fastening recesses 84 are formed in the plastic material of the lens holder 50 and of the holding frame 16, respectively. The fastening projections 82 are preferably formed in one piece with the lens holder 50, for example by injection molding. The fastening recesses 84 can be formed in one piece in the holding frame 16 during the production thereof, for example by injection molding.

Jeder Befestigungsvorsprung 82 des Linsenhalters 50 erstreckt sich stiftartig entlang einer Verbindungsrichtung 86. Zur Befestigung greift der Befestigungsvorsprung 82 entlang der Verbindungsrichtung 86 in die jeweils zugeordnete Befestigungsausnehmung 84 ein.Each fastening projection 82 of the lens holder 50 extends like a pin along a connection direction 86. For fastening, the fastening projection 82 engages in the respectively assigned fastening recess 84 along the connection direction 86.

Die Figur 4 zeigt das Lichtmodul 10 gemäß Figur 1 im endmontierten Zustand. Dabei ist die Sekundäroptikeinheit 18 (Linseneinrichtung) mittels der Positionierungseinrichtung 60 in eine gewünschte Position geführt und mittels der Befestigungseinrichtung 80 in dieser Position fixiert.The Figure 4 shows the light module 10 according to Figure 1 in the final assembled state. The secondary optics unit 18 (lens device) is guided into a desired position by means of the positioning device 60 and is fixed in this position by means of the fastening device 80.

Zur Vorgabe der exakten Position der Linseneinrichtung 18 greift der Passstift 62 in die zugeordnete Passbuchse 64 spielfrei ein. Durch Verschieben des Passstifts 62 in der Passbuchse 64 entlang der Führungsrichtung 66 kann der axiale Abstand der Linseneinrichtung 18 zum Halterahmen 16 präzise eingestellt werden. Eine seitliche Positionierungsungenauigkeit (d.h. senkrecht zur Führungsrichtung 66) wird dadurch vermieden, dass für Passstift 62 und Passbuchse 64 eine spielfreie Passung gewählt wird. Zur Verdeutlichung zeigt die Figur 5 eine Detailansicht der Positionierungseinrichtung 60 in einem Schnitt durch die in Figur 4 mit A-A angedeutete Schnittebene.In order to specify the exact position of the lens device 18, the alignment pin 62 engages in the associated alignment bushing 64 without play. By moving the dowel pin 62 in the socket 64 along the guide direction 66, the axial distance between the lens device 18 and the holding frame 16 can be set precisely. Lateral positioning inaccuracy (ie perpendicular to the guide direction 66) is avoided by the fact that the dowel pin 62 and the socket 64 have a play-free fit is chosen. For clarification, the Figure 5 a detailed view of the positioning device 60 in a section through the in Figure 4 Section plane indicated with AA.

Bei dem in Figur 4 gezeigten Lichtmodul 10 im endmontierten Zustand ist Sekundäroptikeinheit 18 (Linseneinrichtung) mittels der Befestigungseinrichtung 80 in der gewünschten Position fixiert, was nachfolgend erläutert wird.The in Figure 4 The light module 10 shown in the final assembled state, the secondary optics unit 18 (lens device) is fixed in the desired position by means of the fastening device 80, which is explained below.

Jeder stiftartige Befestigungsvorsprung 82 weist einen sich entlang der Verbindungsrichtung 86 erstreckenden Fixierschlitz 88 auf (vergleiche Figur 2). Dies ermöglicht es, den Befestigungsvorsprung 82 in eine gewünschte Tiefe in die Befestigungsausnehmung 84 einzuschieben und dort zu fixieren.Each pin-like fastening projection 82 has a fixing slot 88 extending along the connecting direction 86 (cf. Figure 2 ). This enables the fastening projection 82 to be pushed into the fastening recess 84 to a desired depth and to be fixed there.

Die Figur 6 zeigt zur Erläuterung der Befestigungseinrichtung 80 einen Schnitt entlang einer in Figur 4 mit B-B angedeuteten Ebene. Die Schnittebene verläuft dabei senkrecht zu der Verbindungsrichtung 86.The Figure 6 shows a section along an in FIG Figure 4 level indicated with BB. The cutting plane runs perpendicular to the connection direction 86.

Um den Befestigungsvorsprung 82 in der gewünschten Einschubtiefe innerhalb der Befestigungsausnehmung 84 zu fixieren, umfasst die Befestigungseinrichtung eine Fixierschraube 90. Diese kann durch ein Radialschraubloch 92 (vergleiche auch Figur 3) in die Befestigungsausnehmung 84 eingedreht werden. Das Radialschraubloch 92 ist derart angeordnet, dass die Fixierschraube 90 in Richtung senkrecht zur Verbindungsrichtung 86 eingeschraubt werden kann. Zur Fixierung des Befestigungsvorsprungs 82 in der Befestigungsausnehmung 84 wird die Fixierschraube 90 durch das Radialschraubloch 92 eingedreht, wobei die Fixierschraube 90 auch in den Fixierschlitz 88 des stiftartigen Befestigungsvorsprungs 82 eingreift (vergleiche Figur 6). Durch das Eindrehen der Fixierschraube 90 in den Fixierschlitz 88 wird der Befestigungsvorsprung 82 aufgespreizt und so in der Befestigungsausnehmung 84 fixiert.In order to fix the fastening projection 82 in the desired insertion depth within the fastening recess 84, the fastening device comprises a fastening screw 90. This can be inserted through a radial screw hole 92 (see also FIG Figure 3 ) are screwed into the mounting recess 84. The radial screw hole 92 is arranged in such a way that the fixing screw 90 can be screwed in in the direction perpendicular to the connection direction 86. To fix the fastening projection 82 in the fastening recess 84, the fixing screw 90 is screwed in through the radial screw hole 92, the fixing screw 90 also being inserted into the fixing slot 88 of the pin-like fastening projection 82 engages (compare Figure 6 ). By screwing the fixing screw 90 into the fixing slot 88, the fastening projection 82 is spread apart and thus fixed in the fastening recess 84.

Insbesondere, wenn der Befestigungsvorsprung 82 und die Befestigungsausnehmung 84 aus Kunststoff hergestellt sind, kann so ein formschlüssiger Verbund zwischen Befestigungsvorsprung 82 und Befestigungsausnehmung 84 erzielt werden. Da sich der Fixierschlitz 88 in dem Befestigungsvorsprung 82 entlang der Verbindungsrichtung 86 axial erstreckt, kann der Befestigungsvorsprung 82 in einer gewünschten Einschubtiefe in der Befestigungsausnehmung 84 fixiert werden.In particular, if the fastening projection 82 and the fastening recess 84 are made of plastic, a form-fitting connection between fastening projection 82 and fastening recess 84 can be achieved in this way. Since the fixing slot 88 extends axially in the fastening projection 82 along the connecting direction 86, the fastening projection 82 can be fixed in the fastening recess 84 at a desired insertion depth.
