Description

Die Erfindung betrifft ein LED-Lichtquellensystem für eine LED-Lichteinheit eines Kraftfahrzeuges, wobei das LED-Lichtquellensystem zwei oder mehrere LED-Lichtquellen umfasst, und wobei jede LED-Lichtquelle zumindest eine Leuchtdiode aufweist, und wobei weiters für jede LED-Lichtquelle jeweils zumindest eine Vorsatzoptik vorgesehen ist, und weiters die LED-Lichtquellen auf einem gemeinsamen Montageelement befestigt sind, wobei jede Vorsatzoptik aus einem ersten Vorsatzoptikelement und einem zweiten Vorsatzoptikelement besteht, und das jeweils erste Vorsatzoptikelement mit der zugeordneten LED-Lichtquelle fest verbunden ist, und die zweiten Vorsatzoptikelemente über ein Trägerelement fest miteinander verbunden sind und die zweiten Vorsatzoptikelemente mit dem Trägerelement an dem Montageelement für die LED-Lichtquellen befestigbar und in Bezug auf die LED-Lichtquellen positionierbar sind und wobei erstes und zweites Vorsatzoptikelement mit möglichst geringem Abstand zueinander angeordnet sind.The invention relates to an LED light source system for an LED light unit of a motor vehicle, wherein the LED light source system comprises two or more LED light sources, and wherein each LED light source has at least one light emitting diode, and wherein further for each LED light source at least one Additional optics is provided, and further the LED light sources are mounted on a common mounting element, each attachment optics consists of a first intent optical element and a second intent optical element, and the respective first intent optical element with the associated LED light source is firmly connected, and the second intent optical elements on a support member are fixedly connected to each other and the second intent optical elements with the support member to the mounting member for the LED light sources can be fastened and positioned relative to the LED light sources and wherein first and second intent optical element with the least possible distance to each other are ordered.

Üblicherweise besteht eine LED-Lichtquelle aus einer oder mehreren LEDs, die auf einem LED-Print einer Platine angeordnet sind. Vor den LEDs ist eine Primäroptik angeordnet, mittels welcher das aus den LEDs austretende Licht gesammelt und entsprechend verteilt wird. Durch Mehrfachreflexionen in der Primäroptik kommt es auch zu einer Durchmischung des Lichtes (Integrationswirkung). Von der Primäroptik gelangt das Licht in eine Sekundäroptik, unter Verwendung welcher die gewünschte Lichtverteilung erzielt wird.Usually, an LED light source consists of one or more LEDs, which are arranged on an LED print of a circuit board. In front of the LEDs, a primary optics is arranged, by means of which the light emerging from the LEDs is collected and distributed accordingly. Multiple reflections in the primary optics also lead to a thorough mixing of the light (integration effect). From the primary optics, the light enters a secondary optic, using which the desired light distribution is achieved.

Um die notwendigen Lichtstärken für ein gewünschtes Lichtbild zu erhalten, ist es oftmals notwendig, dass mehrere solcher oben genannter LED-Lichtquellen zur Erzeugung der Lichtverteilung verwendet werden.In order to obtain the necessary luminous intensities for a desired light image, it is often necessary that a plurality of such above-mentioned LED light sources be used to generate the light distribution.

Eine Schwierigkeit bei der Verwendung mehrerer solcher LED-Lichtquellen liegt darin, dass diese sehr genau zueinander ausgerichtet werden müssen, damit ein ordnungsgemäßes Lichtbild erzielt wird. Dies gestaltet bereits die Herstellung solcher LED-Lichtquellensysteme als relativ aufwändig, da auch Toleranzen in der Fertigung der einzelnen Bauteile zu berücksichtigen sind.One difficulty with using multiple such LED light sources is that they must be aligned very accurately with each other for a proper light image. This already makes the production of such LED light source systems as relatively complicated, since tolerances in the production of the individual components are taken into account.

Ein weiteres Problem tritt dann auf, wenn in Folge eines Defektes von LEDs eine oder mehrere LED-Module ausgetauscht werden müssen, da es in der Regel äußerst aufwendig ist, diese wieder möglichst exakt zu positionieren. Außerdem tritt auch noch das Problem der so genannten "Diversität" auf, da für verschiedene Lichtfunktionen unterschiedliche Primäroptiken benötigt werden. Ist diese Diversität untrennbar mit dem LED Modul verknüpft, ist für Servicezwecke eine entsprechend aufwendige Lagerhaltung notwendig.Another problem occurs when one or more LED modules have to be replaced as a result of a defect of LEDs, as it is usually extremely expensive to position them again as accurately as possible. In addition, there is also the problem of the so-called "diversity", as different for different lighting functions Primary optics are needed. If this diversity is inextricably linked with the LED module, a correspondingly expensive storage is necessary for service purposes.

Mit einem eingangs erwähnten LED-Lichtquellensystem können die genannten Probleme bei der Herstellung eines solchen Lichtquellensystems und insbesondere beim Austausch von einer oder mehreren LED-Modulen entschärft werden.With an aforementioned LED light source system, the problems mentioned in the production of such a light source system and in particular in the replacement of one or more LED modules can be defused.

Solche eingangs erwähnten LED-Lichtquellensysteme sind beispielsweise aus der US 4 733 335 A , der US 2003/0123260 A1 , der EP 0 326 668 A2 sowie der US 6 170 971 B1 und der DE 203 14 664 U1 bekannt. Bei den hier vorgestellten Lichtquellensystem handelt es sich um Signalleuchten, die zum Einsatz kommenden Optikelemente weisen gekrümmte, z.B. kugelförmig Ein- bzw. Austrittsflächen auf.Such LED light source systems mentioned above are for example from the US 4,733,335 A , of the US 2003/0123260 A1 , of the EP 0 326 668 A2 as well as the US Pat. No. 6,170,971 B1 and the DE 203 14 664 U1 known. The light source systems presented here are signal lamps, the optics elements used have curved, for example spherical, entry or exit surfaces.

Durch die Unterteilung der Primäroptik in zwei Stufen, von denen die ersten Stufen bzw. Vorsatzoptikelemente jeweils mit den LED-Lichtquellen verbunden sind und die zweiten Stufen bzw. zweiten Vorsatzoptikelemente miteinander verbunden sind, kann eine Referenzierung der einzelnen LED-Lichtquellen zueinander auf einfache Weise über die miteinander verbundenen zweiten Vorsatzoptikelemente erfolgen. Die exakte Ausrichtung der zweiten Stufen zueinander ist dabei durch den Fertigungsprozess gegeben und muss nicht erst beim Zusammenbau des LED-Lichtquellensystems durchgeführt werden, wodurch eine deutlich bessere Referenzierung gewährleistet ist.By subdividing the primary optics in two stages, of which the first stages or intent optical elements are respectively connected to the LED light sources and the second stages or second intent optical elements are connected to each other, a referencing of the individual LED light sources to each other in a simple manner the interconnected second intent optical elements take place. The exact alignment of the second stages to each other is given by the manufacturing process and does not have to be performed until the assembly of the LED light source system, whereby a much better referencing is ensured.

Durch die Verbindung der zweiten Vorsatzoptikelemente miteinander verringert sich die Anzahl der zu justierenden lichttechnischen Komponenten deutlich, sodass die Justierung wesentlich vereinfacht wird.Through the connection of the second attachment optical elements with each other, the number of lighting components to be adjusted decreases significantly, so that the adjustment is much easier.

Bei einem Austausch einer LED-Lichtquelle ist die Positionierung der neuen LED-Lichtquelle weniger heikel, da die eigentliche Referenzierung der LED-Lichtquellen zueinander über die zweiten Vorsatzoptikelemente erfolgt. Bei einem Austausch einer LED-Lichtquelle verändert die Lichtaustrittsfläche der Primäroptik (Vorsatzoptik) ihre Position nicht, da die zweiten Vorsatzoptikelemente ihre Position unverändert beibehalten.When replacing an LED light source, the positioning of the new LED light source is less delicate, since the actual referencing of the LED light sources to each other via the second intent optical elements. When replacing an LED light source, the light emission surface of the primary optics (attachment optics) does not change its position, since the second intent optical elements keep their position unchanged.

Auch Toleranzen in der Fertigung der LED-Lichtquellen oder Abweichungen der Abmessungen der neuen LED-Lichtquellen von den ursprünglich verwendeten Rahmen sind dann in einem gewissen Rahmen weniger problematisch.Tolerances in the production of the LED light sources or deviations in the dimensions of the new LED light sources from the frames originally used are then less problematic to a certain extent.

Unter "Trägerelement" ist dabei grundsätzlich ein beliebiges Element zu verstehen, mit dem es möglich ist, die Vorsatzoptikelemente in zueinander fixen Positionen anzuordnen.Under "support member" is basically an arbitrary element to understand, with which it is possible to arrange the attachment optical elements in mutually fixed positions.

Ein Nachteil bei solchen bekannten LED-Lichtquellensystemen sind die auftretenden Lichtverluste.A disadvantage of such known LED light source systems are the occurring light losses.

Es ist eine Aufgabe der Erfindung, bekannte LED-Lichtquellensysteme zu verbessern.It is an object of the invention to improve known LED light source systems.

Diese Aufgabe wird mit einem eingangs erwähnten LED-Lichtquellensystem dadurch gelöst, dass erfindungsgemäß die Lichtaustrittsflächen der ersten Vorsatzoptikelemente und die Lichteintrittsflächen der zweiten Vorsatzoptikelemente einander parallel gegenüber liegen.This object is achieved with an LED light source system mentioned in the introduction in that, according to the invention, the light exit surfaces of the first intent optical elements and the light entry surfaces of the second ancillary optical elements lie parallel to one another.

Auf diese Weise können die Lichtverluste, insbesondere die die geometrischen Lichtverluste möglichst gering gehalten werden. Optimal ist dabei ein gegen Null gehender Abstand, bei dem die Vorsatzoptikelemente aneinander anliegen, da in diesem Fall die geometrischen Lichtverluste ebenfalls gegen Null gehen.In this way, the light losses, in particular the geometric light losses can be kept as low as possible. Optimal is an approaching zero distance at which the intent optical elements abut each other, since in this case the geometric light losses also go to zero.

Von besonderem Vorteil ist es, wenn die Lichtaustrittsflächen der ersten Vorsatzoptikelemente und die Lichteintrittsflächen der zweiten Vorsatzoptikelemente unmittelbar einander gegenüberliegend positioniert und derart angeordnet sind, dass im Wesentlichen der gesamte Lichtstrom über die Lichtaustrittsfläche aus dem ersten Vorsatzoptikelement aus- und über die Lichteintrittsfläche des zugeordneten zweiten Vorsatzoptikelementes in dieses eintritt.It is particularly advantageous if the light exit surfaces of the first attachment optical elements and the light entry surfaces of the second attachment optical elements are positioned directly opposite each other and arranged such that substantially the entire luminous flux via the light exit surface from the first intent optical element off and on the light entrance surface of the associated second intent optical element enter this.

Die Lichtaustrittsflächen und Lichteintrittsflächen liegen dabei vorzugsweise einander parallel gegenüber.The light exit surfaces and light entry surfaces are preferably parallel to each other.

Durch die spezielle erfindungsgemäße Ausgestaltung bzw. Anordnung der Flächen zueinander geht aufgrund der sogenannten "Integrationswirkung", d.h. in Folge der Lichtdurchmischung auf Grund von innerer Totalreflexion in dem ersten Vorsatzoptikelement, nahezu kein Licht beim Übertritt von dem ersten in das zweite Vorsatzoptikelement auf. Durch diese Integration können auch Toleranzen bei den Bauteilen ausgeglichen werden.Due to the special inventive design or arrangement of the surfaces to each other is due to the so-called "integration effect", i. as a result of the light mixing due to total internal reflection in the first intent optical element, almost no light when passing from the first to the second intent optical element. This integration also tolerances in the components can be compensated.

Grundsätzlich muss man bei den Lichtverlusten zwischen den beiden Flächen der Vorsatzoptikelemente zwischen Reflexionsverlusten und geometrischen Verlusten unterscheiden. Je nach Vergütung der Oberflächen liegen die Reflexionsverluste pro Fläche bei ca. 0,4% - 4%, in Summe also bei ca. 0,8% - 8%. Durch geeignete Maßnahmen können diese Verluste also sehr gering gehalten werden (unter 1%).Basically, one has to differentiate between reflection losses and geometric losses in the light losses between the two surfaces of the optical attachment elements. Depending on the surface finish, the reflection losses per area are approximately 0.4% - 4%, in total about 0.8% - 8%. By taking appropriate measures, these losses can therefore be kept very low (below 1%).

Bei den geometrischen Verlusten handelt es sich um Licht, das seitlich nach dem Austritt aus dem ersten Vorsatzoptikelement an dem zweiten Vorsatzoptikelement vorbeigeht. Diese geometrischen Verluste hängen vom Abstand der Flächen der beiden Vorsatzoptikelemente sowie der konkreten Geometrie der Vorsatzoptikelemente ab.The geometric losses are light that passes laterally after exiting the first intent optical element on the second intent optical element. These geometric losses depend on the distance of the surfaces of the two attachment optical elements and the concrete geometry of the attachment optical elements.

Um die geometrischen Verluste gering halten zu können ist es zweckmäßig, wenn die Lichtaustrittsfläche eines ersten Vorsatzoptikelementes kleiner ist als die Lichteintrittsfläche des zugeordneten zweiten Vorsatzoptikelementes.In order to keep the geometric losses low, it is expedient if the light exit surface of a first intent optical element is smaller than the light entrance surface of the associated second intent optical element.

In diesem Zusammenhang ist es insbesondere von Vorteil, wenn die Lichtaustrittsflächen und die zugeordneten Lichteintrittsflächen derart zueinander angeordnet sind, dass die Normalprojektion der Lichtaustrittsfläche auf die zugeordnete Lichteintrittsfläche vollständig innerhalb der Lichteintrittsfläche liegt.In this context, it is particularly advantageous for the light exit surfaces and the associated light entry surfaces to be arranged relative to one another such that the normal projection of the light exit surface onto the assigned light entry surface lies completely within the light entry surface.

Dadurch, dass bei dieser Variante die Lichteintrittsfläche des zweiten Vorsatzoptikelementes die Lichtaustrittsfläche des ersten Vorsatzoptikelementes an jeder Seite überlappt, können geometrische Lichtverluste völlig verhindert oder zumindest minimiert werden.The fact that in this variant, the light entry surface of the second intent optical element overlaps the light exit surface of the first intent optical element on each side, geometric light losses can be completely prevented or at least minimized.

Nachdem ein solch geringer Abstand fertigungstechnisch schwierig herzustellen ist und auch eine Positionierung der Vorsatzoptikelemente erster und zweiter Stufe zueinander erschwert, ist in der Regel ein geringer Abstand in Form eines Spaltes zwischen erstem und zweiten Vorsatzoptikelement vorgesehen.After such a small distance manufacturing technology is difficult to manufacture and also a positioning of the optical attachment elements first and second stage to each other more difficult, a small gap in the form of a gap between the first and second intent optical element is usually provided.

Um die Reflexionsverluste bei Vorhandensein eines solchen Spaltes zwischen den Vorsatzoptikelementen zu verringern oder ganz auszuschalten, kann weiters vorgesehen sein, dass der Spalt zwischen der Lichtaustrittsfläche des ersten Vorsatzoptikelementes und der Lichteintrittsfläche des zweiten Vorsatzoptikelementes mit einem Füllstoff, welcher den gleichen Brechungsindex wie die beiden Vorsatzoptikelemente aufweist, aufgefüllt ist.In order to reduce or completely eliminate the reflection losses in the presence of such a gap between the optical elements, it may further be provided that the gap between the light exit surface of the first intent optical element and the light entrance surface of the second optical element with a filler having the same refractive index as the two optical elements , is filled up.

Vorzugsweise wird dabei als Füllstoff ein transparentes bzw. Licht leitendes Gel ("Indexgel") verwendet. Das Gel sollte einen ähnlichen oder denselben Brechungsindex wie die Vorsatzoptik haben und möglichst wenig Licht absorbieren.Preferably, a transparent or light-conducting gel ("index gel") is used as the filler. The gel should have a similar or the same refractive index as the optical attachment and absorb as little light as possible.

Bei einem besonders einfach und exakt zu realisierenden. System sind die zweiten Vorsatzoptikelemente einstückig mit dem Trägerelement ausgebildet.In a particularly simple and accurate to implement. System, the second intent optical elements are integrally formed with the carrier element.

Weiters ist es für eine einfache und kostengünstige Fertigung von Vorteil, wenn die zweiten Vorsatzoptikelemente und/oder das Trägerelement aus einem lichtdurchlässigen Kunststoff gebildet sind. Außerdem weist in diesem Fall das System Träger - Vorsatzoptikelemente lediglich ein geringes Gewicht auf, und bei Verwendung eines transparenten Kunststoffes ist es auch möglich, die Vorsatzoptikelemente mit dem Träger einstückig auszubilden.Furthermore, it is for a simple and cost-effective production advantageous if the second intent optical elements and / or the carrier element are formed of a translucent plastic. In addition, in this case, the system carrier - optical attachment elements only a small weight, and when using a transparent plastic, it is also possible to form the optical attachment elements integral with the carrier.

Prinzipiell kann aber das Trägerelement von den zweiten Vorsatzoptikelementen getrennt ausgebildet sein und Aufnahmen oder Haltemittel zum Aufnehmen oder Halten der Vorsatzoptiken aufweisen.In principle, however, the support element may be formed separately from the second attachment optical elements and have receptacles or holding means for receiving or holding the attachment optics.

Weiters kann bei einem erfindungsgemäßen System vorgesehen sein, dass jeder LED-Lichtquelle neben der Primäroptik in Form der Vorsatzoptik eine Sekundäroptik zugeordnet ist, und dass die einzelnen Sekundäroptiken über ein eigenes Sekundäroptik-Trägerelement miteinander verbunden sind.Furthermore, it can be provided in a system according to the invention that each LED light source in addition to the primary optics in the form of intent optics is associated with a secondary optics, and that the individual secondary optics are connected to each other via a separate secondary optics support element.

Die Sekundäroptik kann typischerweise eine Linse oder ein Reflektor sein. Zumeist handelt es sich um Freiform-Linsen bzw. -Reflektoren. Diese Linsen bilden die Austrittsfläche der Vorsatzoptik ins Fernfeld ab und formen dabei die gewünschte Lichtverteilung.The secondary optics may typically be a lens or a reflector. In most cases, they are free-form lenses or reflectors. These lenses project the exit surface of the attachment optics into the far field and form the desired light distribution.

Die Verbindung der einzelnen Sekundäroptiken über ein eigenes Sekundäroptik-Trägerelement bietet wiederum die bereits oben genannten Vorteile im Zusammenhang mit dem Träger für die zweiten Vorsatzoptikelemente.The connection of the individual secondary optics via a separate secondary optics carrier element in turn offers the advantages already mentioned above in connection with the carrier for the second intent optical elements.

Weiters kann es von Vorteil sein, wenn die Sekundäroptiken einstückig mit dem Sekundäroptik-Trägerelement ausgebildet sind.Furthermore, it may be advantageous if the secondary optics are formed integrally with the secondary optics carrier element.

Auch kann es günstig sein, wenn die Sekundäroptiken und/oder das Sekundäroptik-Trägerelement aus einem lichtdurchlässigen Kunststoff gebildet sind.It may also be favorable if the secondary optics and / or the secondary optics carrier element are formed from a translucent plastic.

Schließlich kann es auch von Vorteil sein, wenn das Sekundäroptik-Trägerelement von den Sekundäroptiken getrennt ausgebildet ist und Aufnahmen oder Haltemittel zum Aufnehmen oder Halten der Sekundäroptiken aufweist.Finally, it can also be advantageous if the secondary optics carrier element is formed separately from the secondary optics and has receptacles or holding means for receiving or holding the secondary optics.

Die Vorteile zu diesen Ausgestaltungen des Sekundäroptik-Trägerelementes wurden bereits im Zusammenhang mit dem Träger für die zweiten Vorsatzoptikelemente erörtert.The advantages of these embodiments of the secondary optics carrier element have already been discussed in connection with the carrier for the second intent optical elements.

Zur exakten Positionierung der zweiten Vorsatzoptikelemente in Bezug auf die LED-Prints mit den ersten Vorsatzoptikelementen sind Befestigungsmittel zum Befestigen und Positionieren des Trägerelementes an dem Montageelement vorgesehen.For exact positioning of the second attachment optical elements with respect to the LED prints with the first intent optical elements fastening means for fastening and positioning of the carrier element are provided on the mounting member.

Der Träger ist zum Beispiel durch Stifte an dem Montageelement referenziert und dann an diesem verschraubt/verklebt.The carrier is referenced, for example by pins on the mounting element and then screwed / glued to this.

Weiters ist zweckmäßiger Weise vorgesehen, dass Sekundäroptik-Trägerelement-Befestigungsmittel zum Befestigen und Positionieren des Sekundäroptik-Trägerelementes an dem Montageelement oder zum Befestigen und Positionieren an dem Trägerelement für die zweiten Vorsatzoptikelemente vorgesehen sind.Furthermore, it is expediently provided that secondary optics carrier element fastening means are provided for fastening and positioning the secondary optics carrier element on the mounting element or for fastening and positioning on the carrier element for the second intent optical elements.

Das Montageelement dient als gemeinsame mechanische Referenzierung für das Trägerelement und Sekundäroptik-Trägerelement, weswegen grundsätzlich eine Positionierung des Sekundäroptik-Trägerelementes sowohl an dem Montagelement als auch an dem Träger für die Vorsatzoptikelemente möglich ist. Hinsichtlich der Toleranzen ist es in der Regel günstiger, das Sekundäroptik-Trägerelement an dem Montageelement zu Befestigen und zu Positionieren, da dann das Sekundäroptik-Trägerelement gegenüber dem Träger möglichst genau positioniert werden kann.The mounting element serves as a common mechanical referencing for the support element and secondary optics support element, which is why a positioning of the secondary optics support element is possible both on the mounting element and on the support for the optical attachment elements. With regard to the tolerances, it is generally better to attach and position the secondary optics carrier element on the mounting element, since then the secondary optics carrier element can be positioned as accurately as possible relative to the carrier.

Es kann aber auch vorgesehen sein, dass jeder LED-Lichtquelle neben der Primäroptik in Form der Vorsatzoptik eine Sekundäroptik zugeordnet ist, und dass die einzelnen Sekundäroptiken und die zweiten Vorsatzoptikelemente über einen gemeinsamen Träger miteinander verbunden sind. Auf diese Weise ist lediglich ein Bauteil, nämlich der gemeinsame Träger zu referenzieren.However, it can also be provided that each LED light source is assigned secondary optics in addition to the primary optics in the form of the intent optics, and that the individual secondary optics and the second intent optics are connected to one another via a common carrier. In this way, only one component, namely to refer to the common carrier.

Der Träger kann wieder unterschiedliche Ausgestaltungsformen wie oben schon im Zusammenhang mit den anderen erörterten Trägern annehmen.The wearer may again assume different embodiments as discussed above in connection with the other supports discussed.

Auf Grund der auftretenden geringen Toleranzen könnte es aber auch von Vorteil sein, die zweiten Vorsatzoptikelemente und die Sekundäroptiken in Form von Linsen einstückig auszubilden.Due to the small tolerances that occur, it could also be advantageous to design the second additional optical elements and the secondary optics in the form of lenses in one piece.

Um spezielle Lichtbilder, z.B. eine Abblendlichtverteilung erzielen zu können, kann einer oder mehreren LED-Lichtquellen zumindest je eine Blende zugeordnet sein.To take special photographs, e.g. To be able to achieve a low-beam distribution, one or more LED light sources can be assigned at least one aperture each.

Bei einer besonders vorteilhaften Ausführungsform sind die Blenden jeweils unmittelbar auf der Lichtaustrittsfläche des zweiten Vorsatzoptikelementes angeordnet, z.B. in Form einer Beschichtung der Lichtaustrittsfläche. Diese Variante hat den Vorteil, dass eine Positionierung der Blenden beim Zusammenbau der Lichteinheit nicht notwendig ist, allerdings ist die Herstellung der Vorsatzoptikelemente etwas aufwändiger.In a particularly advantageous embodiment, the diaphragms are each arranged directly on the light exit surface of the second intent optical element, e.g. in the form of a coating of the light exit surface. This variant has the advantage that a positioning of the aperture when assembling the light unit is not necessary, however, the production of the optical attachment elements is a little more complex.

Bei einer anderen Ausführungsform sind die Blenden über einen Blendenträger miteinander verbunden und in einem Abstand zu der Lichtaustrittsflächen angeordnet. Der Blendenträger kann wieder in Bezug auf das Montageelement referenziert sein, d.h. dort befestigt sein.In another embodiment, the panels are connected to one another via a screen carrier and arranged at a distance from the light exit surfaces. The shade support may again be referenced relative to the mounting element, i. be attached there.

Es ist aber auch eine Referenzierung auf den Voratzoptikelement-Träger möglich, oder es können die Linsen auch gleich an diesem Träger oder an einem anderen, z.B. dem oben genannten gemeinsamen Träger gehalten sein.However, it is also possible to refer to the prefabricated optical element carrier, or the lenses can also be held the same on this carrier or on another, for example, the abovementioned common carrier.

Diese Ausführungsform hat den Vorteil, dass, wenn vorgesehen ist, dass die Blenden zumindest in einer Richtung, vorzugsweise im Wesentlichen parallel zu dem Montageelement, verschiebbar oder um zumindest eine Achse verschwenkbar gelagert sind, dies einfach durch Bewegung von lediglich einem Teil erfolgen kann, wenn nämlich der Blendenträger zumindest in einer Richtung, vorzugsweise im Wesentlichen parallel zu dem Montageelement, verschiebbar oder um zumindest eine Achse verschwenkbar gelagert ist. Auf diese Weise ist nur die Bewegung eines Bauteiles, nämlich des Blendenträgers notwendig, und nicht die Bewegung mehrerer einzelner Blenden, und es wird z.B. eine Leuchtweitenregulierung durch Verschiebung der Blenden oder die Realisierung einer anderen erweiterten Lichtfunktion, bei welcher die Hell-Dunkel Linie in der Höhe verstellt werden muss, möglich.This embodiment has the advantage that, if it is provided that the panels are at least in one direction, preferably substantially parallel to the mounting element, slidably mounted or pivotable about at least one axis, this can be done simply by movement of only one part, if namely, the diaphragm support is at least in one direction, preferably substantially parallel to the mounting member, slidably mounted or pivotable about at least one axis. In this way, only the movement of a component, namely the diaphragm support is necessary, and not the movement of several individual diaphragms, and it is e.g. a headlamp leveling by shifting the aperture or the realization of another extended light function, in which the light-dark line must be adjusted in height possible.

Die Figuren 1 und 2 zeigen ein LED-Lichtquellensystem SYS für eine LED-Lichteinheit LEH eines Kraftfahrzeuges, wobei das LED-Lichtquellensystem SYS in dieser Ausführungsform drei LED-Lichtquellen LIQ1, LIQ2, LIQ3 umfasst. Jede LED-Lichtquelle LIQ1, LIQ2, LIQ3 weist zumindest eine Leuchtdiode LED aufweist, wie dies z.B. in Figur 5 angedeutet ist. Die Leuchtdiode(n) LED ist/sind auf einem LED-Print einer Platine LEP angeordnet. Die drei LED-Lichtquellen LIQ1, LIQ2, LIQ3 sind dabei auf einem gemeinsamen Montageelement MON befestigt.The FIGS. 1 and 2 show an LED light source system SYS for a LED light unit LEH of a motor vehicle, wherein the LED light source system SYS in this embodiment comprises three LED light sources LIQ1, LIQ2, LIQ3. Each LED light source LIQ1, LIQ2, LIQ3 has at least one light-emitting diode LED, as shown for example in FIG FIG. 5 is indicated. The light emitting diode (s) LED is / are arranged on an LED print of a board LEP. The three LED light sources LIQ1, LIQ2, LIQ3 are mounted on a common mounting element MON.

Grundsätzlich ist in Lichtaustrittsrichtung vor den Leuchtdioden LED eine Primäroptik in Form von Vorsatzoptiken VOP1, VOP2, VOP3 als Bestandteil der LED-Lichtquellen LIQ1, LIQ2, LIQ3 angeordnet, mittels welcher das aus den Leuchtdioden LED austretende Licht gesammelt und entsprechend verteilt wird. Durch Mehrfachreflexionen in der Primäroptik kommt es auch zu einer Durchmischung des Lichtes (Integrationswirkung). Von der Primäroptik gelangt das Licht in eine Sekundäroptik, unter Verwendung welcher die gewünschte Lichtverteilung erzielt wird.In principle, a primary optics in the form of optical attachments VOP1, VOP2, VOP3 as part of the LED light sources LIQ1, LIQ2, LIQ3 is arranged in the light exit direction in front of the light emitting diodes LED, by means of which the light emerging from the light emitting diodes LED is collected and distributed accordingly. Multiple reflections in the primary optics also lead to a thorough mixing of the light (integration effect). From primary optics The light enters a secondary optics, using which the desired light distribution is achieved.

Bei der vorliegenden Erfindung besteht nun jede Vorsatzoptik VOP1, VOP2, VOP3 aus einem ersten Vorsatzoptikelement VOP11, VOP21, VOP31 und einem zweiten Vorsatzoptikelement VOP12, VOP22, VOP32, die Vorsatzoptiken VOP1, VOP2, VOP3 weisen also einen zweiteiligen Aufbau auf. Das jeweils erste Vorsatzoptikelement VOP11, VOP21, VOP31 ist dabei mit der zugeordneten LED-Lichtquelle LIQ1, LIQ2, LIQ3 fest verbunden ist, und die zweiten Vorsatzoptikelemente VOP12, VOP22, VOP32 sind über ein Trägerelement TRA fest miteinander verbunden.In the present invention, each front optics VOP1, VOP2, VOP3 consists of a first header optical element VOP11, VOP21, VOP31 and a second header optical element VOP12, VOP22, VOP32, the front optics VOP1, VOP2, VOP3 thus have a two-part structure. The respective first intent optical element VOP11, VOP21, VOP31 is fixedly connected to the associated LED light source LIQ1, LIQ2, LIQ3, and the second intent optical elements VOP12, VOP22, VOP32 are firmly connected to one another via a carrier element TRA.

Über das Trägerelement TRA sind die zweiten Vorsatzoptikelemente VOP12, VOP22, VOP32 an dem Montageelement MON für die LED-Lichtquellen LIQ1, LIQ2, LIQ3 befestigbar und in Bezug auf die LED-Lichtquellen LIQ1, LIQ2, LIQ3 positionierbar.Via the carrier element TRA, the second attachment optical elements VOP12, VOP22, VOP32 can be fastened to the mounting element MON for the LED light sources LIQ1, LIQ2, LIQ3 and can be positioned relative to the LED light sources LIQ1, LIQ2, LIQ3.

Durch die Unterteilung der Primäroptik VOP1, VOP2, VOP3 in zwei Stufen, von denen die ersten Stufen bzw. Vorsatzoptikelemente jeweils mit den LED-Lichtquellen verbunden bzw. Bestandteil der LED-Lichtquellen sind und die zweiten Stufen bzw. zweiten Vorsatzoptikelemente miteinander verbunden sind, kann eine Referenzierung der einzelnen LED-Lichtquellen zueinander auf einfache Weise über die miteinander verbundenen zweiten Vorsatzoptikelemente erfolgen. Die exakte Ausrichtung der zweiten Stufen zueinander ist dabei durch den Fertigungsprozess gegeben und muss nicht erst beim Zusammenbau des LED-Lichtquellensystems durchgeführt werden, wodurch eine deutlich bessere Referenzierung gewährleistet ist.By dividing the primary optics VOP1, VOP2, VOP3 in two stages, of which the first stage or intent optical elements respectively connected to the LED light sources or part of the LED light sources and the second stages and second intent optical elements are connected to each other can a referencing of the individual LED light sources to each other in a simple manner via the interconnected second intent optical elements. The exact alignment of the second stages to each other is given by the manufacturing process and does not have to be performed until the assembly of the LED light source system, whereby a much better referencing is ensured.

Durch die Verbindung der zweiten Vorsatzoptikelemente miteinander verringert sich die Anzahl der zu justierenden lichttechnischen Komponenten deutlich, sodass die Justierung wesentlich vereinfacht wird.Through the connection of the second attachment optical elements with each other, the number of lighting components to be adjusted decreases significantly, so that the adjustment is much easier.

Die Lichtaustrittsflächen LA1, LA2, LA3 der ersten Vorsatzoptikelemente VOP11, VOP21, VOP31 und die Lichteintrittsflächen LE1, LE2, LE3 der zweiten Vorsatzoptikelemente VOP12, VOP22, VOP32 sind unmittelbar einander gegenüberliegend positioniert und derart angeordnet sind, dass im Wesentlichen der gesamte Lichtstrom über die Lichtaustrittsfläche LA1, LA2, LA3 aus dem ersten Vorsatzoptikelement VOP11, VOP21, VOP31 aus- und über die Lichteintrittsfläche LE1, LE2, LE3 des zugeordneten zweiten Vorsatzoptikelementes VOP12, VOP22, VOP32 in dieses eintritt.The light exit surfaces LA1, LA2, LA3 of the first header optical elements VOP11, VOP21, VOP31 and the light entry surfaces LE1, LE2, LE3 of the second header optical elements VOP12, VOP22, VOP32 are positioned directly opposite each other and arranged such that substantially the entire luminous flux across the light exit surface LA1, LA2, LA3 from the first intent optical element VOP11, VOP21, VOP31 off and on the light entrance surface LE1, LE2, LE3 of the associated second additional optical element VOP12, VOP22, VOP32 enters this.

Die Lichtaustrittsflächen und Lichteintrittsflächen liegen dabei einander parallel gegenüber.The light exit surfaces and light entry surfaces lie opposite each other in parallel.

Durch die spezielle erfindungsgemäße Ausgestaltung bzw. Anordnung der Flächen zueinander geht aufgrund der sogenannten "Integrationswirkung", d.h. in Folge der Lichtdurchmischung auf Grund von innerer Totalreflexion in dem ersten Vorsatzoptikelement, nahezu kein Licht beim Übertritt von dem ersten in das zweite Vorsatzoptikelement auf. Durch diese Integration können auch Toleranzen bei den Bauteilen ausgeglichen werden.Due to the special inventive design or arrangement of the surfaces to each other is due to the so-called "integration effect", i. as a result of the light mixing due to total internal reflection in the first intent optical element, almost no light when passing from the first to the second intent optical element. This integration also tolerances in the components can be compensated.

Grundsätzlich muss man bei den Lichtverlusten zwischen den beiden Flächen der Vorsatzoptikelemente zwischen Reflexionsverlusten und geometrischen Verlusten unterscheiden. Je nach Vergütung der Oberflächen liegen die Reflexionsverluste pro Fläche bei ca. 0,4% - 4%, in Summe also bei ca. 0,8% - 8%. Durch geeignete Maßnahmen können diese Verluste also sehr gering gehalten werden (unter 1%).Basically, one has to differentiate between reflection losses and geometric losses in the light losses between the two surfaces of the optical attachment elements. Depending on the surface finish, the reflection losses per area are approximately 0.4% - 4%, in total about 0.8% - 8%. By taking appropriate measures, these losses can therefore be kept very low (below 1%).

Bei den geometrischen Verlusten handelt es sich um Licht, das seitlich nach dem Austritt aus dem ersten Vorsatzoptikelement an dem zweiten Vorsatzoptikelement vorbeigeht. Diese geometrischen Verluste hängen vom Abstand der Flächen der beiden Vorsatzoptikelemente sowie der konkreten Geometrie der Vorsatzoptikelemente ab.The geometric losses are light that passes laterally after exiting the first intent optical element on the second intent optical element. These geometric losses depend on the distance of the surfaces of the two attachment optical elements and the concrete geometry of the attachment optical elements.

Um die geometrischen Verluste gering halten zu können, ist die Lichtaustrittsfläche LA1, LA2, LA3 eines ersten Vorsatzoptikelementes VOP11, VOP21, VOP31 kleiner ist als die Lichteintrittsfläche LE1, LE2, LE3 des zugeordneten zweiten Vorsatzoptikelementes VOP12, VOP22, VOP32, und die einander zugeordneten Lichteintrittsflächen LE1, LE2, LE3 sind derart zueinander angeordnet, dass die Normalprojektion der Lichtaustrittsfläche LA1, LA2, LA3 auf die zugeordnete Lichteintrittsfläche LE1, LE2, LE3 vollständig innerhalb der Lichteintrittsfläche LE1, LE2, LE3 liegt.In order to be able to keep the geometric losses low, the light exit surface LA1, LA2, LA3 of a first intent optical element VOP11, VOP21, VOP31 is smaller than the light entrance surface LE1, LE2, LE3 of the associated second auxiliary optical element VOP12, VOP22, VOP32, and the associated light entry surfaces LE1, LE2, LE3 are arranged relative to one another in such a way that the normal projection of the light exit surface LA1, LA2, LA3 onto the assigned light entry surface LE1, LE2, LE3 lies completely within the light entry surface LE1, LE2, LE3.

Dadurch können geometrische Lichtverluste völlig verhindert oder zumindest minimiert werden.As a result, geometric light losses can be completely prevented or at least minimized.

Eine weitere Maßnahme, um die geometrischen Lichtverluste möglichst gering zu halten, besteht darin, dass erstes und zweites Vorsatzoptikelement VOP11, VOP21, VOP31; VOP12, VOP22, VOP32 mit möglichst geringem Abstand zueinander angeordnet sind. Optimal ist dabei ein gegen Null gehender Abstand, bei dem die Vorsatzoptikelemente aneinander anliegen, da in diesem Fall die geometrischen Lichtverluste ebenfalls gegen Null gehen.Another measure to minimize the geometric light losses is that the first and second intent optical element VOP11, VOP21, VOP31; VOP12, VOP22, VOP32 are arranged as close to each other as possible. Optimal is an approaching zero distance at which the intent optical elements abut each other, since in this case the geometric light losses also go to zero.

Nachdem ein solch geringer Abstand fertigungstechnisch schwierig herzustellen ist und auch eine Positionierung der Vorsatzoptikelemente erster und zweiter Stufe zueinander erschwert, ist in der Regel ein geringer Abstand in Form eines Spaltes SPA zwischen erstem und zweiten Vorsatzoptikelement wie gezeigt vorgesehen, wie dies insbesondere in Figur 3 und 4 gut zu erkennen ist.After such a small distance manufacturing technology is difficult to manufacture and also a positioning of the optical attachment elements first and second stage difficult to each other, a small gap in the form of a gap between the first and second optical head element is usually provided as shown, as in particular FIGS. 3 and 4 easy to recognize.

Die zweiten Vorsatzoptikelemente VOP12, VOP22, VOP32 sind einstückig mit dem Trägerelement TRA ausgebildet. Dabei sind die zweiten Vorsatzoptikelemente VOP12, VOP22, VOP32 und das Trägerelement TRA aus einem lichtdurchlässigen Kunststoff gebildet.The second intent optical elements VOP12, VOP22, VOP32 are formed integrally with the carrier element TRA. The second intent optical elements VOP12, VOP22, VOP32 and the carrier element TRA are formed from a translucent plastic.

Außerdem ist, wie schon erwähnt, jeder LED-Lichtquelle LIQ1, LIQ2, LIQ3 neben der Primäroptik in Form der Vorsatzoptik VOP1, VOP2, VOP3 eine Sekundäroptik LEN1, LEN2, LEN3 zugeordnet. Die einzelnen Sekundäroptiken LEN1, LEN2, LEN3 sind über ein eigenes Sekundäroptik-Trägerelement STR miteinander verbunden.In addition, as already mentioned, each LED light source LIQ1, LIQ2, LIQ3 is assigned a secondary optics LEN1, LEN2, LEN3 in addition to the primary optics in the form of the front optics VOP1, VOP2, VOP3. The individual secondary optics LEN1, LEN2, LEN3 are connected to one another via their own secondary optics carrier element STR.

Die Sekundäroptik kann typischerweise eine Linse oder ein Reflektor sein. Zumeist handelt es sich um Freiform-Linsen bzw. -Reflektoren. Diese Linsen bilden die Austrittsfläche der Vorsatzoptik ins Fernfeld ab und formen dabei die gewünschte Lichtverteilung.The secondary optics may typically be a lens or a reflector. In most cases, they are free-form lenses or reflectors. These lenses project the exit surface of the attachment optics into the far field and form the desired light distribution.

Die Verbindung der einzelnen Sekundäroptiken über ein eigenes Sekundäroptik-Trägerelement bietet wiederum die bereits oben genannten Vorteile im Zusammenhang mit dem Träger für die zweiten Vorsatzoptikelemente.The connection of the individual secondary optics via a separate secondary optics carrier element in turn offers the advantages already mentioned above in connection with the carrier for the second intent optical elements.

In der Darstellung sind die Sekundäroptiken LEN1, LEN2, LEN3 einstückig mit dem Sekundäroptik-Trägerelement STR ausgebildet.In the illustration, the secondary optics LEN1, LEN2, LEN3 are integrally formed with the secondary optics support member STR.

Zur exakten Positionierung der zweiten Vorsatzoptikelemente in Bezug auf die LED-Prints mit den ersten Vorsatzoptikelementen sind Befestigungsmittel BEF1 zum Befestigen und Positionieren des Trägerelementes TRA an dem Montageelement MON vorgesehen.For exact positioning of the second intent optical elements with respect to the LED prints with the first intent optical elements fastening means BEF1 are provided for fastening and positioning of the carrier element TRA to the mounting member MON.

Der Träger ist zum Beispiel durch Stifte BEF1 an dem Montageelement MON referenziert und dann an diesem verschraubt/ verklebt.The carrier is referenced for example by pins BEF1 to the mounting member MON and then screwed / glued to this.

Weiters ist zweckmäßiger Weise vorgesehen, dass Sekundäroptik-Trägerelement-Befestigungsmittel BEF2 zum Befestigen und Positionieren des Sekundäroptik-Trägerelementes STR an dem Montageelement MON oder zum Befestigen und Positionieren an dem Trägerelement TRA für die zweiten Vorsatzoptikelemente vorgesehen sind. In dem gezeigten Beispiel erfolgt die Befestigung mittels der Befestigungsmittel BEF2 an dem Träger TRA.Furthermore, it is expediently provided that secondary optics carrier element fastening means BEF2 are provided for fastening and positioning the secondary optics carrier element STR on the mounting element MON or for fastening and positioning on the carrier element TRA for the second intent optical elements. In the example shown, the fastening takes place by means of the fastening means BEF2 on the carrier TRA.

Über die Befestigungsmittel BEF1, BEF2 erfolgt eine Positionierung und Referenzierung der zu referenzierenden Bauteile in Hinblick auf alle 3 Raumachsen. Auf die exakte Art und Weise der Positionierung und Fixierung wird hier allerdings nicht eingegangen, da diese in bekannter Art und Weise erfolgen kann.The fastening means BEF1, BEF2 are used for positioning and referencing the components to be referenced with respect to all three spatial axes. In the exact manner of positioning and fixing is not discussed here, since this can be done in a known manner.

Um spezielle Lichtbilder, z.B. eine Abblendlichtverteilung erzielen zu können, ist jeder LED-Lichtquelle LIQ1, LIQ2, LIQ3 noch je eine Blende BLE1, BLE2, BLE3 zugeordnet.To take special photographs, e.g. To be able to achieve a low-beam distribution, each LED light source LIQ1, LIQ2, LIQ3 is still a respective aperture BLE1, BLE2, BLE3 assigned.

Bei einer anderen Ausführungsform sind die Blenden BLE1, BLE2, BLE3 über einen Blendenträger BTR miteinander verbunden und in einem Abstand zu der Lichtaustrittsflächen LA1', LA2', LA3' angeordnet. Der Blendenträger BTR kann wieder in Bezug auf das Montageelement referenziert sein, d.h. dort befestigt sein. In dem gezeigten Beispiel ist der Blendenträger BTR an den Befestigungsmitteln BEF2 für die Sekundäroptiken angebracht.In another embodiment, the diaphragms BLE1, BLE2, BLE3 are connected to one another via a diaphragm carrier BTR and are arranged at a distance from the light exit surfaces LA1 ', LA2', LA3 '. The shade carrier BTR may again be referenced relative to the mounting element, i. be attached there. In the example shown, the screen carrier BTR is attached to the attachment means BEF2 for the secondary optics.

Es ist aber auch eine Referenzierung auf den Voratzoptikelement-Träger möglich, oder es können die Linsen auch gleich an diesem Träger oder an einem anderen, z.B. dem oben genannten gemeinsamen Träger gehalten sein.However, it is also possible to refer to the prefabricated optical element carrier, or the lenses can also be attached to this carrier or to another, e.g. be held in the abovementioned common carrier.

Wenn vorgesehen ist, dass die Blenden BLE1, BLE2, BLE3 zumindest in einer Richtung, vorzugsweise im Wesentlichen parallel zu dem Montageelement MON, verschiebbar oder um zumindest eine Achse verschwenkbar gelagert sind, geschieht dies einfach durch Bewegung von lediglich einem Teil, indem der Blendenträger BTR zumindest in einer Richtung, vorzugsweise im Wesentlichen parallel zu dem Montageelement MON, verschiebbar oder um zumindest eine Achse verschwenkbar gelagert ist. Auf diese Weise ist nur die Bewegung eines Bauteiles, nämlich des Blendenträgers notwendig, und nicht die Bewegung mehrerer einzelner Blenden, und es wird z.B. eine Leuchtweitenregulierung durch Verschiebung der Blenden oder die Realisierung einer anderen erweiterten Lichtfunktion, bei welcher die Hell-Dunkel Linie in der Höhe verstellt werden muss, möglich.If it is provided that the baffles BLE1, BLE2, BLE3 are at least in one direction, preferably substantially parallel to the mounting member MON, slidably mounted or pivotable about at least one axis, this is done simply by movement of only one part by the screen carrier BTR at least in one direction, preferably substantially parallel to the mounting member MON, slidably mounted or pivotable about at least one axis. In this way, only the movement of a component, namely the diaphragm support is necessary, and not the movement of several individual diaphragms, and it is e.g. a headlamp leveling by shifting the aperture or the realization of another extended light function, in which the light-dark line must be adjusted in height possible.
