Description

Die Erfindung betrifft ein Leuchtmodul für einen Fahrzeugscheinwerfer, wobei das Leuchtmodul zumindest ein durch Beleuchtung mit Laserlicht zur Ausstrahlung von sichtbarem Licht anregbares Leuchtelement und zumindest ein lichtdurchlässiges Trägerelement aufweist, wobei das Trägerelement zumindest eine Lichteintrittsfläche und zumindest eine der Lichteintrittsfläche gegenüberliegende Lichtaustrittsfläche aufweist, wobei das zumindest eine Leuchtelement zur Einstrahlung von Licht in die Lichteintrittsfläche an der zumindest einen Lichteintrittsfläche des Trägerelements angeordnet ist, wobei a) die zumindest eine Lichtaustrittsfläche des Trägerelements durch eine die Lichtaustrittsfläche umrandende lichtundurchlässige Maskierung begrenzt ist oder b) die zumindest eine Lichtaustrittsfläche bis an Seitenflächen des Trägerelements heranreicht, wobei zumindest eine Seitenfläche zwei aneinander angrenzende Seitenabschnitte aufweist, die zur Ausbildung einer Hell-Dunkel-Grenze zueinander geneigt sind, wobei der Fahrzeugscheinwerfer ferner eine Laserlichtquelle zur Anregung des Leuchtelements und eine Projektionslinse, insbesondere eine asphärische Projektionslinse, zur Abbildung des von dem Leuchtmodul abgestrahlten Lichtes auf einen vor dem Fahrzeugscheinwerfer liegenden Bereich aufweist.The invention relates to a lighting module for a vehicle headlight, wherein the lighting module has at least one excitable by illumination with laser light to emit visible light element and at least one translucent support member, wherein the support member has at least one light entrance surface and at least one light entry surface opposite light exit surface, said at least a luminous element is arranged for irradiating light into the light entry surface on the at least one light entry surface of the carrier element, wherein a) the at least one light exit surface of the carrier element is delimited by an opaque masking surrounding the light exit surface or b) reaches at least one light exit surface as far as side surfaces of the carrier element , wherein at least one side surface has two adjoining side portions, which form a light-dark boundary e are inclined to each other, wherein the vehicle headlamp further comprises a laser light source for exciting the luminous element and a projection lens, in particular an aspherical projection lens, for imaging the light emitted by the light module to a light lying in front of the vehicle headlight area.

Leuchtmodule gemäß dem Stand der Technik, welche ein mit Laserlicht zur Ausstrahlung von sichtbarem Licht anregbares Leuchtelement aufweisen, haben den Nachteil, dass das durch das Leuchtelement abgestrahlte Licht im Allgemeinen ungerichtet ist und in Bezug auf eine nachgeschaltete Optik mittels zusätzlicher Bauteile positioniert oder geformt werden muss.Lighting modules according to the prior art which have a light element which can be excited by laser light for emitting visible light have the disadvantage that the light emitted by the luminous element is generally non-directional and has to be positioned or shaped with respect to a downstream optics by means of additional components ,

Hierzu zeigt die JP 2013/196 818 A eine lichtemittierende Vorrichtung mit einem Lichtleiter, welcher Licht zwischen einer Eintrittsfläche und einer Austrittsfläche leitet, einem zur Halterung des Lichtleiters vorgesehenen Halteelement, einer Lichtquelle, einer Platte, welche eine der Größe der Austrittsfläche entsprechende Öffnung aufweist, die an einer Stelle angeordnet ist, wo ein zylindrischer Abschnitt des Halteelements hineinpasst und die Austrittsfläche des Lichtleiters von dem Halteelement gehalten wird, um ein offenes Ende an der Spitze des zylindrischen Abschnitts auszufüllen, und mit einem Wellenlängenkonversionselement, welches das von der Austrittsfläche emittierende Licht absorbiert und die Wellenlänge konvertiert, um Licht eines gegebenen Wellenlängenspektrums zu emittieren.This shows the JP 2013/196 818 A a light-emitting device having a light guide which guides light between an entrance surface and an exit surface, a support member for holding the light guide, a light source, a plate having an opening-surface-sized opening located at a position where cylindrical portion of the holding member and the exit surface of the optical fiber is held by the holding member to fill an open end at the tip of the cylindrical portion, and with a wavelength conversion element which absorbs the light emitted from the exit surface light and converts the wavelength to light of a given Emit wavelength spectrum.

Eine Aufgabe der Erfindung besteht daher darin, diesen Nachteil zu beheben. Diese Aufgabe wird mit einem Leuchtmodul der eingangs genannten Art gelöst, bei welchen erfindungsgemäß die zumindest eine Lichtaustrittsfläche des Leuchtmoduls einen der Bildfeld Wölbung der Projektionslinse angepassten Verlauf aufweist.An object of the invention is therefore to remedy this disadvantage. This object is achieved with a lighting module of the type mentioned, in which, according to the invention, the at least one light exit surface of the lighting module has a curve adapted to the image field curvature of the projection lens.

Bei einer Ausführungsform gemäß Punkt b) könnte die Neigung der Seitenflächen zwischen 15° und 90° betragen. Im Rahmen dieser Offenbarung wird unter dem Ausdruck "Laserlicht" ein von einer Laserlichtquelle abgestrahltes Licht mit einer Wellenlange zwischen 550 und 200 nm verstanden. Vorzugsweise wird blaues Licht mit Wellenlänge von ca. 450 nm eingesetzt. Bei dem Leuchtelement kann es sich beispielsweise um einen Phosphor handeln.In one embodiment according to point b), the inclination of the side surfaces could be between 15 ° and 90 °. In the context of this disclosure, the term "laser light" is understood to mean a light emitted by a laser light source with a wavelength between 550 and 200 nm. Preferably, blue light with a wavelength of about 450 nm is used. The luminous element may be, for example, a phosphor.

Vorteilhafterweise kann vorgesehen sein, dass das Trägerelement aus Glas besteht.Advantageously, it can be provided that the carrier element consists of glass.

Insbesondere kann vorgesehen sein, dass die zumindest eine Lichteintrittsfläche und die zumindest eine Lichtaustrittsfläche zueinander parallel sind.In particular, it can be provided that the at least one light entry surface and the at least one light exit surface are parallel to one another.

Außerdem kann vorgesehen sein, dass das Verhältnis der Lichteintrittsfläche zur Lichtaustrittsfläche zwischen 1:1 und 1:10 beträgt, das Verhältnis des Wertes der Lichtaustrittsfläche gemessen in mm2 zu dem Wert des Abstands zwischen der Lichteintritts- und Lichtaustrittsfläche gemessen in mm kleiner als 2:1 ist und das Verhältnis des Wertes der Lichteintrittsfläche gemessen in mm2 zu dem Wert des Abstands zwischen der Lichteintritts- und Lichteintrittsfläche gemessen in mm kleiner als 1:2 ist. Bei einer Fernlichtanwendung reicht typischerweise ein Lichtbild mit einer Winkelbreite von +/-5° aus. Bei einer typischen Linsenbrennweite von 40mm würde das eine Ausdehnung in der Bildebene von 10mm bedeuten. Verringert sich die Brennweite wird auch dieser Wert kleiner, aber auch die erreichbaren Intensitäten werden reduziert. Um möglichst hohe Intensitäten für den Einsatz des Leuchtmoduls als Fernlicht zu erreichen, macht es Sinn, den Leuchtfleck, also den durch Laserlicht angeregten Bereich des Leuchtelements, sehr klein (0.1mm < D < 1mm) und damit konzentriert auszugestalten und zusätzlich den Abstand zwischen Lichteintritts- und Lichtaustrittsfläche groß zu wählen um die störende Gelbfärbung am Rand des Winkelbereichs abzuschatten. Um die Funktion sinnvoll umzusetzen, ergibt sich eine minimale Distanz zwischen Lichteintritts- und Austrittsfläche von 10mm, bei größeren Distanzen reduziert sich die Lichtnutzungseffizienz des Systems, aber die erreichbare maximale Intensität wird erhöht. Bei einer Anwendung für homogene Ausleuchtung, bei der keine hohen Intensitäten gefordert sind, ist es sinnvoll, einen größeren Leuchtfleck (1mm < D < 10mm) umzusetzen. Hier kann die Distanz zwischen Lichteintritt- und Lichtaustritt auch kleiner 10mm sein. Es gibt aber auch Anwendungen, wo eine hohe Distanz zur Homogenisierung der Beleuchtung eingesetzt wird. Sogenannte Integratorstäbe (Lichteintritt- und austrittsflächen typischerweise ident, Distanz sehr hoch) können genutzt werden, um Lichtbündel verschiedener Lichtquellen zu einem möglichst homogenen Einzellichtbündel zu kombinieren.In addition, it can be provided that the ratio of the light entry surface to the light exit surface is between 1: 1 and 1:10, the ratio of the value of the light exit surface measured in mm 2 to the value of the distance between the light entrance and light exit surface measured in mm less than 2: 1, and the ratio of the value of the light entrance surface measured in mm 2 to the value of the distance between the light entrance surface and the light entrance surface measured in mm is smaller than 1: 2. In a high beam application, a light image with an angular width of +/- 5 ° is typically sufficient. At a typical lens focal length of 40mm, this would mean an expansion in the image plane of 10mm. As the focal length decreases, this value also becomes smaller, but also the achievable intensities are reduced. To achieve the highest possible intensities for the use of the light module as a high beam, it makes sense, the light spot, so excited by laser light region of the light emitting element, very small (0.1mm <D <1mm) and thus concentrated to design and also the distance between light - And light exit area to choose large to shade the disturbing yellowing at the edge of the angle range. In order to implement the function sensibly, there is a minimum distance between light entrance and exit surface of 10 mm, at longer distances the light utilization efficiency of the system is reduced, but the achievable maximum intensity is increased. In an application for homogeneous illumination, in which no high intensities are required, it makes sense to implement a larger light spot (1mm <D <10mm). Here, the distance between light entrance and light exit can be less than 10mm. But there are also applications where a high distance is used to homogenize the lighting. So-called integrator rods (light entry and exit surfaces typically identical, distance very high) can be used to combine light bundles of different light sources to form a homogenous single light bundle.

Zudem kann vorgesehen sein, dass das Trägerelement eine planparallele Platte ist, die vorzugsweise eine Dicke von zumindest 0,2 mm aufweist.In addition, it can be provided that the carrier element is a plane-parallel plate, which preferably has a thickness of at least 0.2 mm.

Insbesondere kann vorgesehen sein, dass die Maskierung aus einer Lackschicht, einem Polymer oder einer metallischen Beschichtung besteht. Eine Maskierung bestehend aus einer metallischen Beschichtung bildet eine reflektierende Oberfläche, die insbesondere bei Hochenergieanwendungen Vorteile aufweist, da eine solche Beschichtung besonders robust ist. Zur Abbildung einer Hell-Dunkel-Grenze direkt am Trägerelement, kann vorgesehen sein, dass die Maskierung die Lichtaustrittsfläche auf eine im Wesentlichen sechseckige geometrische Form begrenzt, welche aus einer Rechteckfläche und einem auf einer Hälfte der Rechteckfläche aufsitzenden Trapezfläche besteht, wobei eine Seitenlinie der Trapezfläche eine Seitenlinie der Rechteckfläche fluchtend verlängert. Die Neigung der Seitenlinie der Trapezfläche, welche der fluchtend verlängernden Seitenlinie gegenüberliegt beträgt zum Beispiel zwischen 15 und 90°.In particular, it can be provided that the masking consists of a lacquer layer, a polymer or a metallic coating. A mask consisting of one Metallic coating forms a reflective surface, which has advantages especially in high-energy applications, since such a coating is particularly robust. For imaging a light / dark boundary directly on the carrier element, it can be provided that the masking delimits the light exit surface to a substantially hexagonal geometric shape, which consists of a rectangular area and a trapezoidal surface seated on one half of the rectangular area, wherein a side line of the trapezoidal area a side line of the rectangular surface extends in alignment. The inclination of the side line of the trapezoidal surface, which faces the aligned extending side line is for example between 15 and 90 °.

Weiterer Aspekt Erfindung betrifft einen Fahrzeugscheinwerfer umfassend ein erfindungsgemäßes Leuchtmodul und eine Laserlichtquelle zur Anregung des Leuchtmoduls bzw. Leuchtelements.Another aspect of the invention relates to a vehicle headlamp comprising a lighting module according to the invention and a laser light source for exciting the lighting module or lighting element.

Erfindungsgemäß ist es vorgesehen, dass der Fahrzeugscheinwerfer ferner eine Projektionslinse, insbesondere eine asphärische Projektionslinse, zur Abbildung des von dem Leuchtmodul abgestrahlten Lichtes auf einen vor dem Fahrzeugscheinwerfer liegenden Bereich aufweist.According to the invention, it is provided that the vehicle headlight also has a projection lens, in particular an aspherical projection lens, for imaging the light emitted by the light module onto a region located in front of the vehicle headlight.

Erfindungsgemäß weist die zumindest eine Lichtaustrittsfläche des Leuchtmoduls einen der Bildfeldwölbung der Projektionslinse angepassten Verlauf auf. Dadurch ist möglich, dass jeder Punkt an der Lichtaustrittsfläche mit den gleichen geometrischen Eigenschaften durch die Linse abgebildet wird, wodurch Abbildungsfehler vermieden werden können.According to the invention, the at least one light exit surface of the light module has a course adapted to the field curvature of the projection lens. This makes it possible that each point is imaged on the light exit surface with the same geometric properties through the lens, whereby aberrations can be avoided.

Darin ist ein Leuchtmodul 1 für einen in Figur 6 dargestellten Fahrzeugscheinwerfer 2 erkennbar, wobei das Leuchtmodul 1 zumindest ein durch Beleuchtung mit Laserlicht zur Ausstrahlung von sichtbarem Licht anregbares Leuchtelement 3 aufweist. Das Leuchtelement 3 ist an der in Figur 2 gezeigten Rückseite eines lichtdurchlässigen Trägerelements 4 angeordnet, an der eine Lichteintrittsfläche 4a ausgebildet ist, wobei das Leuchtelement 3 Licht über die Lichteintrittsfläche 4a in das Trägerelement 4 einstrahlt. Die in Figur 1 gezeigte Vorderseite des Trägerelements 4 weist eine der Lichteintrittsfläche 4a gegenüberliegende Lichtaustrittsfläche 4b auf, die in dem gezeigten Ausführungsbeispiel durch eine lichtundurchlässige Maskierung 5 umrandet und damit begrenzt ist. Die Maskierung 5 kann beispielsweise aus einer Lackschicht, einem Polymer oder einer metallischen Schicht bestehen. Die Maskierung 5 begrenzt die Lichtaustrittsfläche 4b auf eine im Wesentlichen sechseckige geometrische Form, welche aus einer Rechteckfläche 4b' und einer auf einer Hälfte der Rechteckfläche aufliegenden Trapezfläche 4b" besteht, wobei eine Seitenlinie der Trapezfläche 4b" eine Seitenlinie der Rechteckfläche 4b' fluchtend verlängert. Damit kann in einfacher Weise eine Hell-Dunkel-Grenze bereits direkt an der Lichtaustrittsfläche 4b des Leuchtmoduls 1 ausgebildet werden. FIG. 1 shows a front view of a first embodiment of a lighting module according to the invention 1. Darin is a lighting module 1 for a in FIG. 6 Vehicle headlight 2 shown recognizable, wherein the lighting module 1 has at least one excitable by illumination with laser light to emit visible light element 3. The luminous element 3 is at the in FIG. 2 shown rear side of a translucent support member 4, on which a light entrance surface 4a is formed, wherein the luminous element 3 irradiates light via the light entrance surface 4a in the support member 4. In the FIG. 1 shown front side of the support member 4 has a light entrance surface 4a opposite light exit surface 4b, which is surrounded in the embodiment shown by an opaque masking 5 and thus limited. The masking 5 may for example consist of a lacquer layer, a polymer or a metallic layer. The masking 5 delimits the light exit surface 4b to a substantially hexagonal geometric shape, which consists of a rectangular surface 4b 'and a trapezium surface 4b "resting on one half of the rectangular surface, a lateral line of the trapezoidal surface 4b" extending a lateral line of the rectangular surface 4b "in alignment. Thus, a light-dark boundary can already be formed directly on the light exit surface 4b of the light module 1 in a simple manner.

Figur 3 zeigt eine Seitenansicht des Leuchtmoduls 1 gemäß den Figuren 1 und 2. Die Lichteintrittsfläche 4a und die Lichtaustrittsfläche 4b sind vorzugsweise zueinander parallel. Die Dicke d des Trägerelements 4 beträgt vorzugsweise zumindest 0,2 mm. FIG. 3 shows a side view of the lighting module 1 according to the Figures 1 and 2 , The light entry surface 4a and the light exit surface 4b are preferably parallel to each other. The thickness d of the carrier element 4 is preferably at least 0.2 mm.

Figur 4 zeigt eine perspektivische Darstellung einer zweiten Ausführungsform eines Leuchtmoduls 1. Im Gegensatz zur ersten Ausführungsform weist das Leuchtmodul 1 keine Maskierung 5 auf. Das Trägerelement 4 ist so geformt, dass die Lichtaustrittsfläche 4b bis an die Seitenflächen 6a bis 6d des Trägerelement 4 heranreicht, wobei zumindest eine Seitenfläche 6b aneinander angrenzende Seitenabschnitte 6b' und 6b" aufweist, die zur Ausbildung einer Hell-Dunkel-Grenze zueinander geneigt sind. Die Lichtaustrittsfläche 4b wird daher direkt durch die Seitenflächen 6a bis 6d begrenzt. FIG. 4 shows a perspective view of a second embodiment of a lighting module 1. In contrast to the first embodiment, the lighting module 1 no masking 5 on. The carrier element 4 is shaped such that the light exit surface 4b extends up to the side surfaces 6a to 6d of the carrier element 4, wherein at least one side surface 6b has adjoining side sections 6b 'and 6b "which are inclined towards each other to form a light-dark boundary The light exit surface 4b is therefore limited directly by the side surfaces 6a to 6d.

Figur 5 zeigt eine schematische Draufsicht auf das Leuchtmodul 1 gemäß Figur 4. Ähnlich zu dem Leuchtmodul 1 gemäß den Figuren 1 bis 3 weist das Leuchtmodul 1 gemäß der zweiten Ausführungsform ebenso ein Leuchtelement 3 auf, welches Licht in die Lichteintrittsfläche 4a einstrahlt. Dieses Licht kann zudem über die Seitenflächen 6a bis 6d, die reflektierend ausgeführt sind, hin zu der Lichtaustrittsfläche 4b reflektiert werden. Dadurch ist es möglich, die Lichteintrittsfläche 4a kleiner als die Lichtaustrittsfläche 4b auszuführen. FIG. 5 shows a schematic plan view of the lighting module 1 according to FIG. 4 , Similar to the lighting module 1 according to the FIGS. 1 to 3 The lighting module 1 according to the second embodiment also has a lighting element 3, which irradiates light into the light entry surface 4a. This light can also be reflected via the side surfaces 6a to 6d, which are designed to be reflective, toward the light exit surface 4b. Thereby, it is possible to make the light entrance surface 4a smaller than the light exit surface 4b.

Figur 6 zeigt eine schematische Darstellung eines Fahrzeugscheinwerfers 2 mit einem erfindungsgemäßen Leuchtmodul 1. Der Fahrzeugscheinwerfer 2 umfasst ein erfindungsgemäßes Leuchtmodul 1, eine Laserlichtquelle 7 zur Anregung des Leuchtmoduls 1 und eine Projektionslinse 8 zur Abbildung des von dem Leuchtmodul 1 abgestrahlten Lichtes auf einen vor dem Fahrzeugscheinwerfer 2 liegenden Bereich. Die Lichtaustrittsfläche 4b weist eine an die Bildfeldwölbung E der Projektionslinse 8 angepasste Form auf, sodass jeder Punkt an der Lichtaustrittsfläche 4b mit den gleichen Abbildungseigenschaften durch die Projektionslinse 8 abgebildet wird. FIG. 6 shows a schematic representation of a vehicle headlight 2 with a lighting module 1 according to the invention. The vehicle headlight 2 comprises a lighting module 1 according to the invention, a laser light source 7 for exciting the lighting module 1 and a projection lens 8 for imaging the light emitted by the lighting module 1 to a light located in front of the vehicle headlight 2 Area. The light exit surface 4b has a form adapted to the field curvature E of the projection lens 8, so that each point on the light exit surface 4b is imaged by the projection lens 8 with the same imaging properties.
