Abstract
Description
Die Erfindung betrifft eine Kraftfahrzeugbeleuchtung zur Innenraumbeleuchtung oder zur Außenbeleuchtung.The invention relates to a motor vehicle lighting for interior lighting or exterior lighting.
Im Innenraum eines Kraftfahrzeugs sind üblicherweise beachtlich viele Beleuchtungseinrichtungen vorgesehen, die der Beleuchtung verschiedener Gerätschaften wie Instrumente, Griffmulden etc. oder der allgemeinen Innenraumbeleuchtung als Deckenleuchten oder Seitenleuchten (z. B. auch als Ambientenbeleuchtung) dienen. Auch im Außenbereich sind diverse Beleuchtungseinrichtungen vorgesehen, z. B. Heckleuchten oder Scheinwerfer, die der Erkennbarkeit des Fahrzeugs wie auch zur Ausleuchtung des Fahrzeugvorfelds dienen. Zunehmend werden Lichtleiter eingesetzt, in die über eine Lichtquelle Licht eingekoppelt wird, das andernorts am Lichtleiter wieder ausgekoppelt wird. Häufig ist am Lichtleiter im Bereich des Auskoppelabschnitts eine randseitige Optik vorgesehen, die zum seitlichen Auskoppeln des eingestrahlten Lichts dient. Diese Optik ist beispielsweise in Form einer Oberflächenstrukturierung oder dergleichen realisiert. Im Bereich der Oberflächenstrukturierung wird das Licht zur Seite hin reflektiert, so dass es vom Lichtleiter abgestrahlt wird. Mitunter jedoch ist die von der Lichtquelle eingekoppelte Lichtmenge nicht ausreichend, um die geforderte Beleuchtungsaufgabe zu erfüllen. Beispielsweise kann in einem Scheinwerfer nur ein Lichtleiter mit relativ kurzer Länge verwendet werden, das heißt, dass die Länge des Lichtauskoppelabschnitts kurz ist. Nachdem über den Querschnitt des Lichtleiters die einkoppelbare Lichtmenge begrenzt wird, da zu hohe eingekoppelte Lichtleistungen zu einem „Cracken” des Lichtleitermaterials führen können, ist folglich mitunter die Verwendung derartiger Lichtleiter-Lösungen aufgrund der zu geringen auskoppelbaren Lichtmenge nicht möglich.In the interior of a motor vehicle, a considerable number of lighting devices are usually provided which serve the illumination of various equipment such as instruments, recessed grips, etc. or the general interior lighting as ceiling lights or side lights (eg also as ambient lighting). Even in the outdoor area various lighting devices are provided, for. B. tail lights or headlights that serve the visibility of the vehicle as well as the illumination of the vehicle apron. Increasingly, optical fibers are used, into which light is coupled via a light source, which is decoupled elsewhere on the optical fiber. Frequently, an edge-side optics is provided on the light guide in the region of the decoupling section, which serves for the lateral decoupling of the irradiated light. This optics is realized for example in the form of a surface structuring or the like. In the area of surface structuring, the light is reflected to the side so that it is emitted by the light guide. Occasionally, however, the amount of light coupled in by the light source is insufficient to fulfill the required lighting task. For example, in a headlamp, only a light guide having a relatively short length may be used, that is, the length of the light outcoupling section is short. After over the cross section of the light guide the einkoppelbare amount of light is limited, as too high coupled-in light powers can lead to a "cracking" of the optical fiber material, therefore, sometimes the use of such optical fiber solutions due to the low output quantity of light is not possible.
Der Erfindung liegt damit das Problem zugrunde, eine Kraftfahrzeugbeleuchtungseinrichtung anzugeben, die auch in spezielleren Bausituationen die Auskopplung einer hinreichenden Lichtmenge ermöglicht.The invention is therefore based on the problem of specifying a motor vehicle lighting device that allows the extraction of a sufficient amount of light even in more specific construction situations.
Zur Lösung dieses Problems ist erfindungsgemäß vorgesehen, dass der Lichtleiter einen Lichteinkoppelabschnitt bestehend aus mehreren Einzelleiterabschnitten, denen jeweils eine Lichtquelle zugeordnet ist, die in einen gemeinsamen, die Optik aufweisenden Leiterabschnitt münden, aufweist.To solve this problem, the invention provides that the light guide has a light coupling section consisting of a plurality of individual conductor sections, to each of which a light source is assigned, which open into a common conductor section having the optic.
Der bei der erfindungsgemäßen Beleuchtungseinrichtung vorgesehene Lichtleiter besteht aus mehreren Teilabschnitten. Er weist einen speziellen Lichteinkoppelabschnitt auf, der aus mehreren Einzelleiterabschnitten besteht. Diese Einzelleiterabschnitte laufen in einem gemeinsamen Leiterabschnitt zusammen, der die Optik zur Lichtauskopplung zur Seite hin aufweist. Jedem dieser separaten Einzelleiterabschnitte ist eine separate Lichtquelle zugeordnet. Das heißt, dass zum einen die Lichtmenge erhöht werden kann, da nicht nur eine Lichtquelle ihr Licht einkoppelt, sondern mehrere, mithin also die einkoppelbare Lichtmenge ein Vielfaches der Einzellichtquellenlichtmenge beträgt. Darüber hinaus kann auch über den Lichtleiter deutlich mehr Licht ausgekoppelt werden, da der geringe Leiterquerschnitt die Lichteinkoppelmenge nicht mehr begrenzt. Denn infolge der mehreren separaten Einkoppelstellen kann an jeder Stelle eben die maximale Lichtmenge eingekoppelt werden, die der Leiterquerschnitt zulässt. An der Auskoppeloptik wird nun folglich bei der erfindungsgemäßen Beleuchtungseinrichtung ebenfalls wesentlich mehr Licht ausgekoppelt, so dass folglich die Lichtabgabe und damit die Ausleuchtung wesentlich verbessert werden kann.The light guide provided in the lighting device according to the invention consists of several sections. It has a special Lichteinkoppelabschnitt, which consists of several Einzelleiterabschnitten. These individual conductor sections converge in a common conductor section, which has the optics for light extraction to the side. Each of these separate Einzelleiterabschnitte a separate light source is assigned. This means that, on the one hand, the amount of light can be increased, since not only one light source couples in its light, but several, and therefore the amount of light that can be coupled in, is a multiple of the single light source light quantity. In addition, significantly more light can also be coupled out via the light guide, since the small conductor cross-section no longer limits the light input quantity. Because of the multiple separate coupling points can be coupled at any point just the maximum amount of light that allows the conductor cross-section. Consequently, substantially more light is also coupled out at the coupling-out optics in the illumination device according to the invention, so that consequently the light output and thus the illumination can be substantially improved.
Gemäß einer zweckmäßigen Erfindungsausgestaltung sind zwei Einzelleiterabschnitte vorgesehen, die mit dem Leiterabschnitt eine Y-förmige Anordnung bilden, wobei die Einzelleiter bevorzugt gebogen in den gemeinsamen Leiterabschnitt übergehen. Diese gebogene Leiterführung ist für die Führung des Lichts im Leiterinneren zweckmäßig.According to an expedient embodiment of the invention, two individual conductor sections are provided which form a Y-shaped arrangement with the conductor section, the individual conductors preferably being bent over into the common conductor section. This curved ladder guide is useful for guiding the light inside the ladder.
Gemäß einer besonders zweckmäßigen Weiterbildung der Erfindung ist vorgesehen, dass die Enden der Einzelleiter in einer gemeinsamen Ebene liegen. Insbesondere bei Verwendung zweier Einzelleiter in Y-Konfiguration, insbesondere wenn sie gebogen geführt sind, kann das Licht in einer gemeinsamen Ebene eingekoppelt werden, das heißt, dass die Lichtquellen ebenfalls in einer gemeinsamen Ebene angeordnet sind, beispielsweise an einer gemeinsamen Leiterplatte. Der Lichtleiter ist lediglich so zu positionieren, dass die Einzelleiterabschnitte benachbart zu den Lichtquellen angeordnet sind, sodass sie insgesamt eine baulich kompakte Ausgestaltung ergibt.According to a particularly advantageous embodiment of the invention it is provided that the ends of the individual conductors lie in a common plane. In particular, when using two individual conductors in the Y configuration, in particular if they are guided bent, the light can be coupled in a common plane, that is, the light sources are also arranged in a common plane, for example on a common circuit board. The light guide is merely to be positioned so that the individual conductor sections are arranged adjacent to the light sources, so that overall they result in a structurally compact design.
Als Lichtquellen werden bevorzugt LEDs verwendet, die besonders kleinbauend sind und, wie zuvor erwähnt, sich ohne weiteres auf einer gemeinsamen Leiterplatte anordnen lassen. Die Lichtquellenanordnung ist sehr klein, gleichwohl sind mit LEDs sehr hohe Lichtmengen erzeugbar und einkoppelbar, so dass mit der erfindungsgemäßen Beleuchtungseinrichtung eine sehr gute Ausleuchtung erreichbar ist.As light sources LEDs are preferably used, which are particularly small-sized and, as mentioned above, can be easily arranged on a common circuit board. The light source arrangement is very small, however, with LEDs very high amounts of light can be generated and coupled, so that with the illumination device according to the invention a very good illumination can be achieved.
Eine erfindungsgemäße Kraftfahrzeugbeleuchtungseinrichtung ist bevorzugt ein Frontscheinwerfer, bei dem mittels des Lichtleiters ein Tagfahrlicht in Form eines Lichtbands, der aufgrund der Flexibilität des Lichtleiters nahezu beliebig verlaufen kann, realisiert ist. Denkbar wäre auch die Realisierung eine Blinklichts.A motor vehicle lighting device according to the invention is preferably a headlight in which by means of the light guide a daytime running light in the form of a light band, which can run almost arbitrarily due to the flexibility of the light guide, is realized. It would also be conceivable to realize a flashing light.
Weitere Vorteile und Einzelheiten der vorliegenden Erfindung ergeben sich aus den im Folgenden beschriebenen Ausführungsbeispielen sowie anhand der Zeichnung. Dabei zeigen:Further advantages and details of the present invention will become apparent from the embodiments described below and with reference to the drawing. Showing:
Die Kraftfahrzeugbeleuchtung
Zum Einkoppeln des Lichts weist der Lichtleiter
Dem Lichtleiter
Da hier zwei Lichtquellen
Anstelle eines Tagfahrlichts könnte auch ein Blinklicht, also ein Blinker realisiert werden, Hierzu wären als Lichtquellen solche zu verwenden, die gelbes Licht emittieren, also z. B. gelbe LEDs. Diese würden zur Realisierung des Blinklichts bei Bedarf intermittierend angesteuert, so dass sie blinkend ihr emittiertes Licht in die Einzelleiterabschnitte einkoppeln. Ein lichtstarker Blinker kann somit auf einfache Weise realisiert werden.Instead of a daytime running light, a flashing light, so a turn signal could be realized, this would be to use as light sources such that emit yellow light, so z. B. yellow LEDs. These would be intermittently driven to realize the flashing light, if necessary, so that they blink flashing their emitted light in the Einzelleiterabschnitte. A high-intensity turn signal can thus be realized in a simple manner.
Ferner ist es möglich, in der Farbe unterschiedliches Licht emittierende Lichtquellen
Alternativ wäre es auch denkbar, jedem Einzelleiterabschnitt jeweils z. B. eine weißes Licht und eine gelbes Licht emittierende Lichtquelle bzw. LED zuzuordnen, so dass mittels der Beleuchtungseinrichtung sowohl ein Tagfahrlicht als auch ein Blinklicht realisiert ist, jedoch jeweils mittels zweier Lichtquellen, so dass in jeder Betriebsart die doppelt Lichtmenge eingekoppelt werden kann. Wird z. B. die Blinfunktion benötigt, so werden die weißes Licht emittierenden Lichtquelle aus- und die gelbes Licht emittierenden Lichtquellen eingeschaltet, und umgekehrt, was durch geeignete Ansteuerung und Anordnung der Lichtquellen am Träger ohne weiteres möglich ist.Alternatively, it would also be conceivable, each Einzelleiterabschnitt each z. B. assign a white light and a yellow light emitting light source or LED, so that by means of the illumination device both a daytime running light and a flashing light is realized, but each by means of two light sources, so that in each mode, the double amount of light can be coupled. If z. B. the Blinfunktion needed, the white light emitting light source off and the yellow light emitting light sources are turned on, and vice versa, which is readily possible by suitable control and arrangement of the light sources on the carrier.
Grundsätzlich sind mittels der erfindungsgemäßen Beleuchtungseinrichtung natürlich aus andere Leuchten als Tagfahrlicht und Blinker realisierbar.Basically, by means of the illumination device according to the invention of course other lights as daytime running lights and turn signals can be realized.
