Description

Die vorliegende Erfindung betrifft eine Beleuchtungseinrichtung für Fahrzeuge mit einer in einem Gehäuse enthaltenden Hauptlichtquelle und einer Zusatzlichtquelle. The present invention relates to a lighting device for vehicles with a in a housing containing main light source and an additional light source.

Es ist bekannt in ein Scheinwerfermodul für das Fern- und Abblendlicht beispielsweise einen Fahrtrichtungsanzeiger zu integrieren. Hierfür wird die Lichtquelle für den Fahrtrichtungsanzeiger in den Reflektor des Fern- und Abblendlichts eingesetzt. It is known for example in a headlamp module for the high and low beams to integrate a direction indicator. For this, the light source for the Direction indicators inserted in the reflector of the high and low beams.

Außerdem ist aus der DE 196 52 159 A1 eine Beleuchtungseinrichtung, wie z. B. ein Scheinwerfer für Abblend- und Fernlicht, bekannt, der mit einer Begrenzungsleuchte kombiniert ist. Hierfür wird das Licht einer separaten Lichtquelle über einen Lichtleiter in ein Lichtleitelement eingekoppelt, das an der Abdeckscheibe oder am Rand des Scheinwerfergehäuses angeordnet ist und hierdurch eine Begrenzungsleuchte bildet. In addition, from DE 196 52 159 A1 a lighting device such. B. a Headlights for low and high beam, known with a position lamp is combined. For this purpose, the light from a separate light source is transmitted through a light guide a light guide element coupled, which on the cover plate or on the edge of Headlight housing is arranged and thereby forms a marker lamp.

Es ist die Aufgabe der vorliegenden Erfindung, eine verbesserte Beleuchtungseinrichtung für Fahrzeuge der eingangs genannten Art bereitzustellen. Insbesondere soll die Beleuchtungseinrichtung einen geringen Raumbedarf haben und flexibel an das Fahrzeugdesign anpassbar sein. It is the object of the present invention to provide an improved lighting device to provide for vehicles of the type mentioned. In particular, the Lighting device have a small footprint and flexible to that Vehicle design to be customizable.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Abstrahlfläche des von der Hauptlichtquelle emittierten Lichts von zumindest einem lichtleitenden Element, in welches das Licht der Zusatzlichtquelle eingekoppelt wird, zumindest teilweise durchsetzt ist. According to the invention this object is achieved in that the radiation surface of the Main light source emitted light from at least one light-guiding element, in which the light of the additional light source is coupled in, at least partially penetrates is.

Vorteilhaft an dieser Lösung ist, daß der Raumbedarf für die Haupt- und Zusatzlichtfunktion sehr viel geringer ist als bei separaten Einheiten für diese Lichtfunktionen. Außerdem ist es nicht erforderlich, die Zusatzlichtquelle in unmittelbarer Nähe des Moduls für die Hauptlichtquelle vorzusehen, da die Abstrahlung des Lichts der Zusatzlichtquelle nicht über herkömmliche optische Reflexions- und Projektionselemente erfolgt, sondern über eine optische Einkopplung in das lichtleitende Element. Diese Einkopplung kann beispielsweise über Lichtleiter erfolgen. The advantage of this solution is that the space required for the main and Additional light function is much less than with separate units for these light functions. Moreover it is not necessary to use the additional light source in the immediate vicinity of the module Main light source to be provided, since the radiation of the light of the additional light source is not via conventional optical reflection and projection elements, but via an optical coupling into the light-guiding element. This coupling can for example via light guides.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung sind die lichtleitenden Elemente Stäbe, die in dem Gehäuse zwischen der Hauptlichtquelle und einer Abdeckscheibe angeordnet sind. Die lichtleitenden Stäbe können insbesondere beabstandet voneinander angeordnet sein. Bei dieser Ausgestaltung wird die Lichtfunktion der Hauptlichtquelle bei der Betätigung der Zusatzlichtquelle nur insoweit beeinträchtigt, als daß die Abstrahlfläche der Hauptlichtquelle von den lichtemittierenden Stäben der Zusatzlichtquelle durchsetzt ist. Die Lichtfunktion der Hauptlichtquelle bleibt dabei jedoch weiterhin wirksam. According to an advantageous embodiment of the invention, the light-guiding elements Rods that are in the housing between the main light source and a cover plate are arranged. The light-conducting rods can in particular be spaced apart from one another be arranged. In this embodiment, the light function of the main light source is the operation of the additional light source is only affected to the extent that the Radiation area of the main light source from the light-emitting rods of the additional light source is enforced. However, the light function of the main light source remains effective.

Gemäß einer weiteren erfindungsgemäßen Ausgestaltung kann das lichtleitende Element oder die lichtleitenden Elemente in einer Abdeckscheibe der Beleuchtungseinrichtung gebildet sein. Insbesondere kann dabei das lichtleitende Element in der Abdeckscheibe eine diffuses Licht abstrahlende Fläche bilden. Vorteilhaft an dieser Ausgestaltung ist, daß kein separates Element für die Lichtemission der Zusatzlichtquelle vorgesehen werden muß. Die spezielle Ausgestaltung der Abdeckscheibe der Beleuchtungseinrichtung stellt das lichtleitende Element für die Zusatzlichtquelle bereit. Diese Lösung ist somit sehr Platz und Kosten sparend. According to a further embodiment of the invention, the light-guiding element or the light-guiding elements in a cover plate of the lighting device be educated. In particular, the light-guiding element can be in the cover plate form a diffuse light radiating surface. The advantage of this configuration is that no separate element is provided for the light emission of the additional light source must become. The special design of the cover plate of the lighting device provides the light-guiding element for the additional light source. So this solution is very space and cost saving.

Gemäß einer weiteren erfindungsgemäßen Ausgestaltung kann das lichtleitende Element eine transluzente, diffuses Licht abstrahlende Fläche zwischen der Hauptlichtquelle und einer Abdeckscheibe bilden. Bei dieser Ausgestaltung ist man bei dem Design der Abdeckscheibe unabhängig von dem Design des lichtleitenden Elements für die Zusatzlichtquelle. According to a further embodiment of the invention, the light-guiding element a translucent, diffuse light radiating surface between the main light source and form a cover plate. With this configuration one is in the design of the Cover plate regardless of the design of the light-guiding element for the Additional light source.

Die erfindungsgemäße Beleuchtungseinrichtung kann ein Projektions- oder Reflexionsscheinwerfer sein, wobei insbesondere die Hauptlichtquelle eine Fernlicht- und/oder Abblendlichtquelle und die Zusatzlichtquelle die Lichtquelle eines Fahrtrichtungsanzeigers sein kann. The lighting device according to the invention can be a projection or Reflective headlights, in particular the main light source a high beam and / or Low beam light source and the additional light source the light source of a direction indicator can be.

Außerdem kann die Beleuchtungseinrichtung auch eine Heckleuchte sein. Ferner kann die Hauptlichtquelle die Lichtquelle eines Fahrtrichtungsanzeigers und die Zusatzlichtquelle eine Standlichtquelle sein. Gemäß einer vorteilhaften Ausgestaltung ist dabei in Abhängigkeit von der Betätigung des Fahrtrichtungsanzeigers die Standlichtquelle abschaltbar. In addition, the lighting device can also be a rear light. Furthermore, the main light source is the light source of a direction indicator and the Additional light source to be a parking light source. According to an advantageous embodiment, in Depending on the actuation of the direction indicator, the parking light source switched off.

Die vorliegende Erfindung wird nun anhand von Ausführungsbeispielen mit Bezug auf die Zeichnungen erläutert. The present invention will now be described using exemplary embodiments with reference to FIG Drawings explained.

Fig. 1 zeigt einen Querschnitt durch ein Ausführungsbeispiel der erfindungsgemäßen Beleuchtungseinrichtung und Fig. 1 shows a cross section through an embodiment of the lighting device according to the invention and

Fig. 2 zeigt eine Aufsicht auf ein weiteres Ausführungsbeispiel der erfindungsgemäßen Beleuchtungseinrichtung. Fig. 2 shows a plan view of a further embodiment of the illumination device according to the invention.

Gemäß dem ersten Ausführungsbeispiel ist die Beleuchtungseinrichtung ein Scheinwerfermodul, dessen Hauptlichtfunktion das Abblend- und Fernlicht ist. Hierfür ist eine Hauptlichtquelle 1, die eine Glühlampe oder eine Gasentladungslampe sein kann, in einen Reflektor 3 eingesetzt. Außerdem kann der Scheinwerfer als Projektionsscheinwerfer ausgebildet sein. In diesem Fall wäre in Abstrahlrichtung A der Hauptlichtquelle 1 eine Projektionslinse angeordnet. According to the first exemplary embodiment, the lighting device is a headlight module, the main light function of which is the low and high beam. For this purpose, a main light source 1 , which can be an incandescent lamp or a gas discharge lamp, is inserted into a reflector 3 . In addition, the headlamp can be designed as a projection headlamp. In this case, a projection lens would be arranged in the radiation direction A of the main light source 1 .

Die Lichtquelle für das Abblend- und Fernlicht ist in einem Gehäuse 2 untergebracht, das bei seiner Lichtaustrittsöffnung eine lichtdurchlässige Abdeckscheibe 6 aufweist. Diese Abdeckscheibe kann aus Glas oder Kunststoff bestehen. Vorzugsweise ist sie im wesentlichen glatt ausgebildet. Sie kann jedoch auch optische Elemente aufweisen, durch welche die Abstrahlrichtung des Lichts beeinflußt wird. The light source for the low and high beam is housed in a housing 2 , which has a translucent cover plate 6 at its light exit opening. This cover plate can be made of glass or plastic. It is preferably essentially smooth. However, it can also have optical elements through which the direction of radiation of the light is influenced.

Durch das Scheinwerfermodul wird eine sog. Abstrahlfläche gebildet, durch welche das abgestrahlte Licht der Hauptlichtquelle 1 hindurchtritt. Sie ist von außen sichtbar und umfasst bei einer Ansicht von außen zumindest einen Teil der Abdeckscheibe 6. A so-called radiation surface is formed by the headlight module, through which the emitted light of the main light source 1 passes. It is visible from the outside and, when viewed from the outside, comprises at least part of the cover plate 6 .

Zwischen der Hauptlichtquelle 1 und der Abdeckscheibe 6 ist eine weitere Scheibe 5 eingesetzt, die als lichtleitendes Element wirkt. Das lichtleitende Element 5 durchsetzt somit die Abstrahlfläche der Hauptlichtquelle 1. In das lichtleitende Element 5 wird das Licht einer Zusatzlichtquelle 4 eingekoppelt. Im vorliegenden Ausführungsbeispiel wird durch die Zusatzlichtquelle 4 ein Fahrtrichtungsanzeiger bereitgestellt. Hierfür sind am Rande des lichtleitenden Elements 5 gelbe Lumineszenzdioden (LEDs) angeordnet, deren Lichtemission in die Randfläche des lichtleitenden Elements 5 eingekoppelt wird. Das Licht der LEDs wird dann von dem lichtleitenden Element 5 diffus abgestrahlt, so daß von außen das lichtleitende Element 5 als diffuses gelbes Licht abstrahlende Fläche erscheint. Außerdem ist das lichtleitende Element 5 transluzent, so daß auch das von der Hauptlichtquelle 1 emittierte Licht hindurchtritt und weiterhin seine Lichtfunktion erfüllt. Between the main light source 1 and the cover plate 6 , a further plate 5 is inserted, which acts as a light-guiding element. The light-guiding element 5 thus penetrates the radiation surface of the main light source 1 . The light of an additional light source 4 is coupled into the light-guiding element 5 . In the present exemplary embodiment, a direction indicator is provided by the additional light source 4 . For this purpose 5 yellow luminescent diodes (LEDs) are arranged on the edge of the light-guiding element, the light emission of which is coupled into the edge surface of the light-guiding element 5 . The light from the LEDs is then diffusely emitted by the light-guiding element 5 , so that the light-guiding element 5 appears from the outside as a diffuse surface emitting yellow light. In addition, the light-guiding element 5 is translucent, so that the light emitted by the main light source 1 also passes through and continues to fulfill its light function.

Gemäß einer Weiterbildung dieses Ausführungsbeispiels können die gelben LEDs der Zusatzlichtquelle 4 nicht am Rand des lichtleitenden Elements 5 vorgesehen sein, sondern entfernt von dem Scheinwerfermodul, wobei die Lichteinkopplung in diesem Fall über zusätzlich vorzusehende Lichtleiter erfolgt. Außerdem kann auch das lichtleitende Element 5 nicht als separates Element ausgeführt sein, sondern in der Abdeckscheibe 6 integriert sein. In diesem Fall wird das Licht der Zusatzlichtquelle 4 in entsprechende Abschnitte der Abdeckscheibe 6 eingekoppelt und die Abdeckscheibe 6 selbst bzw. Teile dieser Abdeckscheibe 6 emittieren das Licht der Zusatzlichtquelle 4. According to a further development of this exemplary embodiment, the yellow LEDs of the additional light source 4 cannot be provided at the edge of the light-guiding element 5 , but rather away from the headlight module, in which case the light is coupled in via additional light guides to be provided. In addition, the light-guiding element 5 may not be designed as a separate element, but may be integrated in the cover plate 6 . In this case, the light from the additional light source 4 is coupled into corresponding sections of the cover plate 6 and the cover plate 6 itself or parts of this cover plate 6 emit the light from the additional light source 4 .

In Fig. 2 ist ein zweites Ausführungsbeispiel für die Beleuchtungseinrichtung gezeigt. Hier ist die Hauptlichtquelle 1 die Lichtquelle eines Fahrtrichtungsanzeigers und die Zusatzlichtquelle eine Standlichtquelle. In diesem Fall kann die Beleuchtungseinrichtung insbesondere eine Heckleuchte sein. In FIG. 2, a second embodiment is shown for the illumination device. Here the main light source 1 is the light source of a direction indicator and the additional light source is a parking light source. In this case, the lighting device can in particular be a rear light.

Das Modul für den Fahrtrichtungsanzeiger wird in üblicher Weise von einer Lichtquelle 1, einem Gehäuse 2 und einer Abdeckscheibe 6 gebildet. Vorteilhafterweise strahlt die Hauptlichtquelle 1 dabei gelbes Licht ab und die Abdeckscheibe 6 ist farblos, klar und glatt ausgebildet. Für die Bereitstellung des Standlichts durchsetzen die Abstrahlfläche des Fahrtrichtungsanzeigers lichtleitende Stäbe 7, die beabstandet voneinander angeordnet sind. In diese lichtleitenden Stäbe 7 wird das Licht der Standlichtquelle 1 beispielsweise über Lichtleiter eingekoppelt. Die Oberflächen der Stäbe 7 sind in Abstrahlrichtung der Beleuchtungseinrichtung so ausgebildet, daß Licht in diese Richtung emittiert wird. Vorteilhafterweise erfolgt die Schaltung des Fahrtrichtungsanzeigers und der Standlichtquelle so, daß bei Betätigung des Fahrtrichtungsanzeigers, d. h. bei einer Lichtemission durch die Hauptlichtquelle 1, die Zusatzlichtquelle für das Standlicht abgeschaltet wird. Hierdurch wird sichergestellt, daß die Lichtfunktion des Fahrtrichtungsanzeigers durch das Standlicht nicht beeinträchtigt wird. The module for the direction indicator is formed in the usual way by a light source 1 , a housing 2 and a cover 6 . Advantageously, the main light source 1 emits yellow light and the cover plate 6 is colorless, clear and smooth. To provide the parking light, the light emitting surface of the direction indicator penetrates light-conducting rods 7 , which are arranged at a distance from one another. The light from the parking light source 1 is coupled into these light-conducting rods 7 , for example via light guides. The surfaces of the rods 7 are formed in the radiation direction of the lighting device so that light is emitted in this direction. The direction indicator and the auxiliary light source are advantageously switched in such a way that when the direction indicator is actuated, ie when the main light source 1 emits light, the auxiliary light source for the auxiliary light is switched off. This ensures that the light function of the direction indicator is not affected by the parking light.
