Beleuchtungsvorrichtung für ein Fahrzeug mit zwei Gruppen von Lichtquellen für zumindest zwei LichtfunktionenLighting device for a vehicle with two groups of light sources for at least two light functions

Die vorliegende Erfindung betrifft eine Beleuchtungsvorrichtung für ein Fahrzeug mit einer ersten Gruppe von ersten Lichtquellen und einer zweiten Gruppe von zweiten Lichtquellen, wobei den Lichtquellen der beiden Gruppen zumindest zum Teil verschiedene Lichtfunktionen zugeordnet sind und wobei der von den ersten Lichtquellen gebildete Bereich den von den zweiten Lichtquellen gebildeten Bereich vollständig umschließt,The present invention relates to a lighting device for a vehicle having a first group of first light sources and a second group of second light sources, wherein the light sources of the two groups at least partially associated with different light functions and wherein the area formed by the first light sources that of the second Completely encloses light sources,

Kraftfahrzeugleuchten, insbesondere Heckleuchten, die anstelle von Glühlampen oder Quarzlampen Leuchtdioden (LED: light emitting diode) als Leuchtmittel einsetzen, sind aus dem Stand der Technik hinlänglich bekannt. Nur beispielhaft wird auf die DE 33 15 785 A1 , DE 39 16 875 A1 , DE 39 30 214 A1 und DE 42 28 895 A1 verwiesen, die Kraftfahrzeug- bzw. Signalleuchten betreffen, welche Leuchtdioden als Leuchtmittel einsetzen.Motor vehicle lights, in particular tail lights, which use light-emitting diodes (LED: light emitting diode) instead of incandescent lamps or quartz lamps as light sources, are well known from the prior art. For example, reference is made to DE 33 15 785 A1, DE 39 16 875 A1, DE 39 30 214 A1 and DE 42 28 895 A1, which relate to motor vehicle or signal lights, which use light-emitting diodes as lighting means.

Ferner ist aus der DE 100 52 655 A1 eine Beleuchtungsvorrichtung für Kraftfahrzeuge bekannt, bei der um die Projektionslinse eines Scheinwerfers eine mit Leuchtdioden bestückte Kreisringfläche angeordnet ist. Durch die auf der Ringfläche angeordneten Leuchtdioden können zusätzliche Signalleuchtflächen bereitgestellt werden. Sie können auch als Standlicht öder Blinklicht dienen. Das die Leuchtdioden umfassende Leuchtmodul umgibt somit die Abstrahlfläche des Projektionsscheinwerfers.Furthermore, DE 100 52 655 A1 discloses a lighting device for motor vehicles, in which a circular ring surface equipped with light-emitting diodes is arranged around the projection lens of a headlight. By arranged on the annular surface LEDs additional signal light areas can be provided. They can also serve as a parking light or flashing light. The lighting module comprising the light emitting diode thus surrounds the emission surface of the projection headlight.

Schließlich ist aus der DE 10 2004 013 082 A1 eine Beleuchtungsvorrichtung für Fahrzeuge bekannt, die ein erstes Leuchtmodul mit Leuchtdioden als Lichtquellen sowie ein zweites Leuchtmodul umfasst, dessen Lichtquelle hinter dem ersten Leuchtmodul angeordnet ist, wobei das von der zweiten Lichtquelle emittierte Licht durch eine ringförmige Zwischenscheibe abgestrahlt wird, welche das erste Leuchtmodul umgibt. Diese Beleuchtungsvorrichtung hat den Vorteil, dass der Bauraumbedarf in einer senkrecht zur Abstrahlrichtung verlaufenden Querschnittsrichtung gering ist. Nachteilhafterweise ist der Bauraumbedarf hinter dem ersten Leuchtmodul, d.h. in einer zur Abstrahlrichtung entgegengesetzten Richtung, jedoch relativ groß. Bei Fahrzeugen, deren Karosserie unter Gesichtspunkten der Aerodynamik und des Designs optimiert ist, ist der für die Beleuchtungsvorrichtungen vorgesehene Bauraum sehr gering. Es ist daher erforderlich, den Aufbau der Beleuchtungsvorrichtung an die Erfordernisse des für die Beleuchtungsvorrichtung vorgesehenen Bauraums anzupassen.Finally, DE 10 2004 013 082 A1 discloses a lighting device for vehicles which comprises a first light-emitting module with light-emitting diodes as light sources and a second light-emitting module whose light source is arranged behind the first light-emitting module, wherein the light emitted by the second light source passes through an annular light-emitting diode Washer is emitted, which surrounds the first light module. This lighting device has the advantage that the space requirement is low in a direction perpendicular to the emission direction cross-sectional direction. Disadvantageously, the space requirement behind the first lighting module, ie in a direction opposite to the direction of radiation, but relatively large. In vehicles whose bodywork is optimized from the point of view of aerodynamics and design, the space available for the lighting devices is very large low. It is therefore necessary to adapt the structure of the lighting device to the requirements of the space provided for the lighting device.

Es ist die Aufgabe der vorliegenden Erfindung, eine Beleuchtungsvorrichtung der eingangs genannten Art bereitzustellen, die insbesondere in einer Richtung entgegen der Abstrahlrichtung der Beleuchtungsvorrichtung so wenig Bauraum wie möglich benötigt. Gleichzeitig sollen zumindest zwei, bevorzugt mehrere Lichtfunktionen mit den Lichtquellen der Beleuchtungsvorrichtung realisiert werden können.It is the object of the present invention to provide a lighting device of the type mentioned, which requires as little space as possible, in particular in a direction opposite to the emission direction of the lighting device. At the same time, at least two, preferably several, light functions should be able to be realized with the light sources of the lighting device.

Erfindungsgemäß wird diese Aufgabe durch eine Beleuchtungsvorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Aus- und Weiterbildungen ergeben sich aus den Unteransprüchen.According to the invention, this object is achieved by a lighting device having the features of claim 1. Advantageous embodiments and further developments emerge from the subclaims.

Die erfindungsgemäße Beleuchtungsvorrichtung ist dadurch gekennzeichnet, dass die ersten und zweiten Lichtquellen im Wesentlichen in einer Ebene angeordnet sind. Dabei ist die Ebene insbesondere im Wesentlichen senkrecht zur Lichtemissionsrichtung der Beleuchtungsvorrichtung ausgerichtet. Hierdurch kann im Vergleich zu der in der DE 10 2004 013 082 A1 vorgeschlagenen Lösung Bauraum in einer Richtung entgegen der Abstrahlrichtung der Beleuchtungsvorrichtung gewonnen werden. Die Beleuchtungsvorrichtung lässt sich somit insbesondere bei Fahrzeugen einsetzen, bei denen in dieser Richtung wenig Platz für die Beleuchtungsvorrichtung zur Verfügung steht.The lighting device according to the invention is characterized in that the first and second light sources are arranged substantially in one plane. In this case, the plane is aligned, in particular, substantially perpendicular to the light emission direction of the illumination device. As a result, in comparison to the solution proposed in DE 10 2004 013 082 A1, installation space can be obtained in a direction opposite to the emission direction of the illumination device. The lighting device can thus be used in particular in vehicles in which there is little space available for the lighting device in this direction.

Gemäß einer bevorzugten Ausbildung der erfindungsgemäßen Beleuchtungsvorrichtung sind die ersten und zweiten Lichtquellen iichtemittierende Dioden, die auf einer gemeinsamen Platine befestigt sind. Eine auf diese Weise ausgebildete Beleuchtungsvorrichtung lässt sich sehr kostengünstig herstellen und montieren, da die Anzahl der Teile der Beleuchtungsvorrichtung reduziert wird.According to a preferred embodiment of the lighting device according to the invention, the first and second light sources are light-emitting diodes which are mounted on a common board. A lighting device formed in this way can be manufactured and installed very inexpensively, since the number of parts of the lighting device is reduced.

Gemäß einer weiteren bevorzugten Ausgestaltung der erfindungsgemäßen Beleuchtungsvorrichtung sind die ersten Lichtquellen in der Mitte der Platine angeordnet und die zweiten Lichtquellen umgeben die ersten Lichtquellen ringförmig. Die Abstrahlfläche der ersten Lichtfunktion ist in diesem Fall insbesondere eine Scheibe und die Abstrahlfläche der zweiten Lichtfunktion ein Kreisring, der die Scheibe einschließt, oder ein Teilkreisring. Eine Beleuchtungsvorrichtung gemäß dieser Ausgestaltung besitzt ein besonders charakteristisches Erscheinungsbild, welches den Wiedererkennungswert des Fahrzeugs und des Herstellers steigert. Gemäß einer bevorzugten Weiterbildung der erfindungsgemäßen Beleuchtungsvorrichtung ist in Lichtemissionsrichtung vor der Platine ein Reflektormodul angeordnet, welches Öffnungen zum Durchtritt der Lichtquellen aufweist, wobei die Lichtquellen von gewölbten Reflektoren umgeben sind. An dem Reflektormodul ist bevorzugt auf der den Lichtquellen abgewandten Seite des Reflektormoduls vor den ersten Lichtquellen eine Zwischenscheibe in Lichtemissionsrichtung angeordnet.According to a further preferred embodiment of the lighting device according to the invention, the first light sources are arranged in the middle of the board and the second light sources surround the first light sources annularly. In this case, the emission surface of the first light function is in particular a disk and the emission surface of the second light function is a circular ring which encloses the disk or a partial ring ring. A lighting device according to this embodiment has a particularly characteristic appearance, which enhances the recognition value of the vehicle and the manufacturer. According to a preferred embodiment of the lighting device according to the invention, a reflector module is arranged in the light emission direction in front of the board, which has openings for the passage of the light sources, wherein the light sources are surrounded by curved reflectors. An intermediate disk in the light emission direction is preferably arranged on the reflector module on the side of the reflector module facing away from the light sources in front of the first light sources.

Bei der Beleuchtungsvorrichtung handelt es sich insbesondere um eine Heckleuchte für ein Kraftfahrzeug. Die Lichtfunktion des Bremslichts wird von den ersten Lichtquellen bereitgestellt, die Lichtfunktion eines Fahrtrichtungsanzeigers von den zweiten Lichtquellen oder einem Teil dieser und die Lichtfunktion eines Schlusslichts von den ersten und zweiten Lichtquellen. Die Leuchtdioden können dabei zumindest zum Teil Duo-Leuchtdioden sein, die in einer und/oder einer zweiten Farbe leuchten können. Insbesondere die zweiten Lichtquellen oder zumindest ein Teil dieser zweiten Leuchtdioden sind als Duo-Leuchtdioden ausgebildet. Zur Bereitstellung eines Fahrtrichtungsanzeigers leuchten diese Leuchtdioden des zweiten Leuchtmoduls in einer Farbe, die sich von der Farbe für die Bereitstellung der Schlusslichtfunktion und der Bremslichtfunktion unterscheidet.The lighting device is in particular a tail light for a motor vehicle. The light function of the brake light is provided by the first light sources, the light function of a turn signal from the second light sources or a part thereof, and the light function of a tail light from the first and second light sources. The light-emitting diodes can be at least partially duo light-emitting diodes, which can shine in one and / or a second color. In particular, the second light sources or at least a part of these second light-emitting diodes are designed as duo light-emitting diodes. To provide a turn signal, these light emitting diodes of the second light module glow in a color that differs from the color for the provision of the tail light function and the brake light function.

Die Erfindung wird nun anhand eines Ausführungsbeispiels mit Bezug zu den Zeichnungen erläutert.The invention will now be explained with reference to an embodiment with reference to the drawings.

Das Ausführungsbeispiel betrifft eine Heckleuchte eines Kraftfahrzeugs, welche die Lichtfunktionen des Bremslichts, des Schlusslichts und des Fahrtrichtungsanzeigers bereitstellt.The embodiment relates to a tail lamp of a motor vehicle, which provides the light functions of the brake light, the tail light and the direction indicator.

Die Heckleuchte weist Gehäuseteile 6 auf, welche in einer Aufnahmeaussparung der Karosserie des Fahrzeugs aufgenommen sind. Nach außen wird das Gehäuse 6 von einer Abdeckscheibe bzw. Lichtscheibe 5 abgeschlossen, die auf einer Seite an die Fuge der Heckklappe angrenzt. Im Inneren der Aufnahmeaussparung für die Heckleuchte sind die Gehäuseteile 6 mit einer Halterung 7 über Dichtelemente verbunden.The tail light has housing parts 6, which are received in a receiving recess of the body of the vehicle. To the outside, the housing 6 is closed off by a cover disk or light disk 5 which adjoins the joint of the tailgate on one side. Inside the receiving recess for the rear light, the housing parts 6 are connected to a holder 7 via sealing elements.

An der Halterung 7 ist eine Platine 11 (Fig. 3) befestigt. Die Platine 11 ist scheibenförmig und in zwei Bereiche unterteilt, die in Fig. 3 durch die gestrichelte Linie T getrennt werden. In dem ersten Bereich 3 ist eine erste Gruppe von ersten Lichtquellen 1 befestigt, in dem zweiten Bereich 4 ist eine zweite Gruppe von zweiten Lichtquellen 2 befestigt. Bei den Lichtquellen beider Gruppen handelt es sich um lichtemittierende Dioden (LEDs). Wie es sich insbesondere in Fig. 1 erkennen lässt, umfasst die erste Gruppe insgesamt 16 Leuchtdioden, von denen eine zentral in der Mitte der Scheibe des Bereichs 3 angeordnet ist und fünf bzw. 10 weitere Leuchtdioden diese zentrale Leuchtdiode konzentrisch umgeben. Die Leuchtdioden 2 der zweiten Gruppe umfassen insgesamt 20 Leuchtdioden, welche äquidistant auf dem Kreisring des Bereichs 4 der Platine 11 so angeordnet sind, dass sie die Leuchtdioden 1 der ersten Gruppe konzentrisch umgeben. Der von den ersten Lichtquellen 1 gebildete Bereich 3 wird somit von dem durch die zweiten Lichtquellen 2 gebildeten Bereich 4 vollständig umschlossen.On the holder 7, a board 11 (Fig. 3) is attached. The board 11 is disc-shaped and divided into two areas, which are separated in Fig. 3 by the dashed line T. By doing First region 3 is a first group of first light sources 1 attached, in the second region 4, a second group of second light sources 2 is attached. The light sources of both groups are light emitting diodes (LEDs). As can be seen in particular in FIG. 1, the first group comprises a total of 16 light-emitting diodes, one of which is arranged centrally in the middle of the pane of the area 3 and five or 10 further light-emitting diodes surround this central light-emitting diode concentrically. The LEDs 2 of the second group comprise a total of 20 LEDs, which are arranged equidistantly on the annulus of the area 4 of the board 11 so that they surround the light emitting diodes 1 of the first group concentric. The region 3 formed by the first light sources 1 is thus completely enclosed by the region 4 formed by the second light sources 2.

Die Platine 11 mit den Leuchtdioden 1 und 2 beider Gruppen bildet eine Ebene E, so dass auch die Lichtquellen 1 und 2 in dieser Ebene E angeordnet sind. Die Ebene E ist, wie aus Fig. 2 ersichtlich, im Wesentlichen senkrecht zur Lichtemissionsrichtung L der Heckleuchte ausgerichtet.The board 11 with the light emitting diodes 1 and 2 of both groups forms a plane E, so that the light sources 1 and 2 are arranged in this plane E. The plane E is, as shown in FIG. 2, aligned substantially perpendicular to the light emission direction L of the taillight.

Vor der Platine 11 , auf der die Lichtquellen 1 und 2 befestigt sind, ist ein Reflektormodul 8 angeordnet. Dieses Reflektormodul 8 weist für jede Leuchtdiode 1 und 2 eine Öffnung auf, durch welche der Kopf der Leuchtdiode 1 und 2 jeweils durchtritt. Die Leuchtdioden sind dann von gewölbten Reflektoren 9 umgeben, welche eine im Wesentlichen parallele Lichtemission in Richtung des Pfeils L der Fig. 2 erzeugen. Auf der den Leuchtdioden 1 der ersten Gruppe abgewandten Seite weist das Reflektormodul 8 in Lichtemissionsrichtung L eine Zwischenlichtscheibe 10 auf, so dass das von den Leuchtdioden 1 emittierte Licht zunächst durch die Zwischenlichtscheibe durchtritt, um danach durch die Lichtscheibe 5 nach außen emittiert zu werden. Die Zwischenlichtscheibe 10 ist beispielsweise über eine Rastverbindung mit dem Reflektormodul 8 verbunden.In front of the board 11, on which the light sources 1 and 2 are fixed, a reflector module 8 is arranged. This reflector module 8 has, for each light-emitting diode 1 and 2, an opening through which the head of the light-emitting diode 1 and 2 respectively passes. The light-emitting diodes are then surrounded by curved reflectors 9 which generate a substantially parallel light emission in the direction of the arrow L of FIG. 2. On the side facing away from the light-emitting diodes 1 of the first group, the reflector module 8 in the light emission direction L an intermediate lens 10, so that the emitted light from the light emitting diodes 1 first passes through the intermediate lens to be subsequently emitted through the lens 5 to the outside. The intermediate lens 10 is connected for example via a latching connection with the reflector module 8.

Die Leuchtdioden 1 und 2 der beiden Gruppen sind über die Leiterbahnen auf der Platine 11 und Steckanschlüsse mit einem Steuergerät für die Heckleuchte verbunden. Das Steuergerät kann die Leuchtdioden 1 und 2 so ansteuern, dass sie unterschiedlich hell leuchten. Es sind insbesondere zumindest zwei Helligkeiten ansteuerbar.The light-emitting diodes 1 and 2 of the two groups are connected via the conductor tracks on the board 11 and plug-in connections with a control unit for the taillight. The control unit can control the light-emitting diodes 1 and 2 so that they shine differently bright. In particular, at least two brightnesses can be controlled.

Die Leuchtdioden 1 emittieren rotes Licht, um eine Schlusslichtfunktion und eine Bremslichtfunktion bereitzustellen. Dabei können die Leuchtdioden 2 der zweiten Gruppe zumindest zum Teil ggf. als sog. Duo-Leuchtdioden ausgebildet sein, die in zwei verschiedenen Farben leuchten können, um einen Fahrtrichtungsanzeiger bereitzustellen, der in einer anderen Farbe, üblicherweise in orange, leuchtet als die Leuchtdioden für die Schlusslichtfunktion und die Bremslichtfunktion, wie dies bei europäischen Fahrzeugen der Fall ist. Falls der Fahrtrichtungsanzeiger als Blinklicht ausgeführt ist, das in der gleichen Farbe leuchtet wie das Schluss- und Bremslicht, wie dies bei US-amerikanischen Fahrzeugen der Fall ist, werden keine Duo-Leuchtdioden benötigt.The light-emitting diodes 1 emit red light to provide a tail light function and a brake light function. In this case, the light-emitting diodes 2 of the second group may be formed, if necessary, at least in part as so-called duo light-emitting diodes, which may be illuminated in two different colors to provide a direction indicator which shines in a different color, usually orange, than the light-emitting diodes for the tail light function and the brake light function, as is the case with European vehicles. If the Direction indicator is designed as a flashing light that shines in the same color as the tail and brake light, as is the case with US vehicles, no duo LEDs are required.

Das Steuergerät kann die Heckleuchte so ansteuern, dasstσtgende Beleuchtungsfunktionen bereitgestellt werden können:The control unit can control the tail light in such a way that relevant illumination functions can be provided:

Für die Schlusslichtfunktion leuchten die Leuchtdioden 1 und 2 der ersten und zweiten Gruppe in einer ersten niedrigeren Helligkeit in der gleichen Farbe, d. h. hier in rot. Es wird somit eine scheibenförmige Abstrahlfläche mit homogener Helligkeit durch die Lichtscheibe 5 abgestrahlt. .For the tail light function, the light emitting diodes 1 and 2 of the first and second groups are illuminated in a first lower brightness in the same color, i. H. here in red. It is thus emitted a disc-shaped radiating surface with a homogeneous brightness through the lens 5. ,

Um die Bremslichtfunktion bereitzustellen werden die Lichtquellen 1 der ersten Gruppe so angesteuert, dass sie heller leuchten als das dies bei der Schlusslichtfunktion der Fall ist. Es erscheint in diesem Fall somit die Lichtcharakteristik einer hellen zentralen Scheibe, die von einem weniger hellen Kreisring umgeben ist, welcher in der gleichen Farbe leuchtet.In order to provide the brake light function, the light sources 1 of the first group are controlled so that they shine brighter than is the case with the tail light function. In this case, therefore, the light characteristic of a bright central disc appears, which is surrounded by a less bright circular ring, which shines in the same color.

Zur Bereitstellung eines Fahrtrichtungsanzeigers, der in der gleichen Farbe leuchtet wie das Schlusslicht und das Bremslicht, wird die Helligkeit der Leuchtdioden 2 der zweiten Gruppe oder eines Teils dieser Leuchtdioden 2 intermittierend erhöht. Soll ein Fahrtrichtungsanzeiger bereitgestellt werden, der in einer anderen Farbe leuchtet, werden die Duo-Leuchtdioden so angesteuert, dass die zweite Farbe dieser Leuchtdioden 2 intermittierend, d.h. als Blinklicht, aufleuchtet. Die andere Farbe des Schlusslichts, welche in diesem Fall durch die Duo- Leuchtdioden 2 bereitgestellt wird, bleibt hiervon unbeeinflusst. Die Abstrahlfläche für die Lichtfunktion des Fahrtrichtungsanzeigers umgibt somit vollständig oder teilweise die Abstrahlfläche für die Lichtfunktion des Bremslichts. Beispielsweise kann zur Bereitstellung des Fahrtrichtungsanzeigers ein voller Kreisring oder ein Halbkreisring der Leuchtdioden 2 blinken.To provide a direction indicator which shines in the same color as the tail light and the brake light, the brightness of the light emitting diodes 2 of the second group or a part of these light emitting diodes 2 is increased intermittently. If a direction indicator is to be provided which illuminates in a different color, the duo LEDs are driven so that the second color of these LEDs 2 intermittently, i. as a flashing light, it lights up. The other color of the tail light, which is provided in this case by the duo LEDs 2, remains unaffected. The radiating surface for the light function of the direction indicator thus completely or partially surrounds the radiating surface for the light function of the brake light. For example, a full circular ring or a semicircular ring of the LEDs 2 may blink to provide the direction indicator.

Gemäß einer anderen Ausgestaltung dieses Ausführungsbeispiels weist die Platine 11 im Bereich der gestrichelten Linie T der Fig. 3 einen Schlitz auf, welcher den ersten Bereich 3 und den zweiten Bereich 4 der Platine 11 trennt. Die beiden Bereiche 3 und 4 sind jedoch über Stege verbunden, welche den Schlitz unterbrechen.According to another embodiment of this embodiment, the board 11 in the region of the dashed line T of Fig. 3 has a slot which separates the first region 3 and the second region 4 of the board 11. However, the two areas 3 and 4 are connected by webs which interrupt the slot.

Es könnte aber auch vorgesehen sein, die Bereiche 3 und 4 nicht über Stege zu verbinden, so dass zwei getrennte Platinen vorhanden wären.However, it could also be provided that areas 3 and 4 are not connected by webs, so that two separate boards would be present.

Aufgrund von Fertigungs-/Montagetoleranzen wäre es dann möglich, dass die jeweiligen Ebenen der Lichtquellen 1 , 2 geringfügig voneinander abweichen. Es ist jedoch bereits ausreichend, wenn die Lichtquellen 1 , 2 im Wesentlichen in einer Ebene angeordnet sind. BezugszeichenlisteDue to manufacturing / assembly tolerances, it would then be possible that the respective levels of the light sources 1, 2 differ slightly from each other. However, it is already sufficient if the light sources 1, 2 are arranged substantially in one plane. LIST OF REFERENCE NUMBERS
