Description

Die Erfindung betrifft eine Kraftfahrzeugleuchte gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a motor vehicle lamp according to the preamble of claim 1.

Eine Kraftfahrzeugleuchte besteht im Wesentlichen aus einem Gehäuse, mindestens einem darin angeordneten Leuchtmittel für wenigstens eine Lichtfunktion, gegebenenfalls mindestens einem typischerweise hinter dem Leuchtmittel in dem Gehäuse angeordneten oder durch dieses beispielsweise vermittels einer zumindest teilweisen Beschichtung gebildeten Reflektor und/oder zumindest einem vor dem Leuchtmittel angeordnete Optikelement, wie etwa einer Linse, einem Rinnenkonzentrator, z.B. einer Parabolrinne (CPC; Compound Parabolic Concentrator) oder dergleichen zur Ausformung einer definierten Abstrahlcharakteristik, sowie einer das wenigstens eine Leuchtmittel und gegebenenfalls den mindestens einen Reflektor bzw. das zumindest eine Optikelement gegen Witterungseinflüsse schützenden, kurz auch als Lichtscheibe bezeichneten transparenten Abdeckung. Die Lichtscheibe umschließt gemeinsam mit dem Gehäuse einen das mindestens eine Leuchtmittel und gegebenenfalls den zumindest einen Reflektor beherbergenden Leuchteninnenraum. In dem Leuchteninnenraum kann zwischen Leuchtmittel und Lichtscheibe wenigstens eine Optikscheibe angeordnet sein, welche beispielsweise eine bestimmte Struktur und/oder Maskierung aufweisen kann, beispielsweise um bei einer klaren, für einen Betrachter eine Tiefenwirkung bewirkenden Lichtscheibe das Leuchtmittel zu kaschieren. Das Gehäuse bzw. der Leuchteninnenraum kann dabei in mehrere Kammern mit jeweils eigenen Leuchtmitteln, eventuell Reflektoren und/oder Optikscheiben, sowie gegebenenfalls Lichtscheiben unterteilt sein, von denen mehrere Kammern gleiche oder jede Kammer eine andere Lichtfunktionen erfüllen kann.A motor vehicle luminaire essentially comprises a housing, at least one luminous means arranged therein for at least one light function, optionally at least one reflector typically arranged behind the luminous means in the housing or formed by this for example by means of an at least partial coating and / or at least one arranged in front of the luminous means Optical element, such as a lens, a trough concentrator, eg a parabolic trough (CPC) or the like for shaping a defined emission characteristic, as well as a transparent cover which briefly protects the at least one light source and optionally the at least one reflector or the at least one optical element against the effects of weathering. The lens encloses, together with the housing, a luminaire interior accommodating the at least one luminous means and, if appropriate, the at least one reflector. In the luminaire interior, at least one optical disc can be arranged between the illuminant and the lens, which can have a specific structure and / or masking, for example, in order to conceal the luminous means in the case of a clear lens effecting a depth effect for a viewer. The housing or the lamp interior can be subdivided into several chambers, each with its own light sources, possibly reflectors and / or optical discs, and optionally light disks, of which several chambers can perform the same or each chamber a different light functions.

Die Kraftfahrzeugleuchte erfüllt je nach Ausgestaltung eine oder mehrere Aufgaben bzw. Funktionen. Zur Erfüllung jeder Aufgabe bzw. Funktion ist hierbei eine Lichtfunktion der Kraftfahrzeugleuchte vorgesehen. Dabei können mehrere Lichtfunktionen von einem oder mehreren Leuchtmitteln erfüllt werden. Lichtfunktionen sind beispielsweise bei einer Ausgestaltung als Scheinwerfer eine die Fahrbahn ausleuchtende Funktion, oder bei einer Ausgestaltung als Signalleuchte eine Signalfunktion, wie beispielsweise eine Wiederholblinklichtfunktion zur Fahrtrichtungsanzeige oder eine Bremslichtfunktion zur Anzeige einer Bremstätigkeit, oder z.B. einer Begrenzungslichtfunktion, wie etwa einer Rücklichtfunktion, zur Sicherstellung einer Sichtbarkeit des Kraftfahrzeugs bei Tag und/oder Nacht, wie etwa bei einer Ausgestaltung als Heckleuchte oder Tagfahrleuchte. Beispiele für Kraftfahrzeugleuchten sind am Fahrzeugbug, an den Fahrzeugflanken und/oder an den Seitenspiegeln sowie am Fahrzeugheck angeordnete Blinkleuchten, Ausstiegsleuchten, beispielsweise zur Umfeldbeleuchtung, Begrenzungsleuchten, Bremsleuchten, Nebelleuchten, Rückfahrleuchten, sowie typischerweise hoch gesetzte dritte Bremsleuchten, so genannte Central, High-Mounted Braking Lights, Tagfahrleuchten, Scheinwerfer und auch als Abbiege- oder Kurvenlicht verwendete Nebelscheinwerfer, sowie Kombinationen hiervon.Depending on the design, the motor vehicle light fulfills one or more tasks or functions. To fulfill each task or function in this case a light function of the motor vehicle light is provided. Several light functions can be fulfilled by one or more light sources. Light functions, for example, in one embodiment as a headlamp a function illuminating the roadway, or in one embodiment as a signal light a Signal function, such as a Wiederholblinklichtfunktion to the direction indicator or a brake light function to indicate a braking action, or as a limiting light function, such as a taillight function, to ensure visibility of the vehicle during the day and / or night, such as in a design as tail light or daytime running light. Examples of motor vehicle lights are on the vehicle's bow, on the vehicle flanks and / or on the side mirrors and rear lights arranged flashing lights, for example, ambient lighting, marker lights, brake lights, fog lamps, reversing lights, and typically high set third brake lights, so-called Central, High-Mounted Braking lights, daytime running lights, headlamps and fog lights used as turning or cornering lights, as well as combinations thereof.

Ein Leuchtmittel für wenigstens eine Lichtfunktion umfasst zumindest wenigstens eine Lichtquelle, beispielsweise mindestens eine Glühlampe oder mindestens eine Gasentladungslampe oder mindestens eine Leuchtdiode sowie gegebenenfalls Kombinationen hiervon.A luminous means for at least one light function comprises at least at least one light source, for example at least one incandescent lamp or at least one gas discharge lamp or at least one light-emitting diode and optionally combinations thereof.

Beispielsweise kommen als Lichtquelle von Leuchtmitteln für Kraftfahrzeugleuchten unter anderem wegen ihres geringen Stromverbrauchs vermehrt Leuchtdioden zum Einsatz. Diese bestehen aus mindestens einem Lichtemittierende-Diode-Halbleiter-Chip, kurz LED-Chip, sowie wenigstens einer beispielsweise durch Spritzgießen angeformten, den mindestens einen LED-Chip ganz oder teilweise umhüllenden Primäroptik. Auch sind Kraftfahrzeugleuchten bekannt, in denen reine LED-Chips ohne angeformte Primäroptiken zum Einsatz kommen. Im Folgenden wird deshalb der Einfachheit halber nicht mehr zwischen Leuchtdiode und LED-Chip unterschieden und statt dessen einheitlich der Begriff LED stellvertretend für beide Ausgestaltungen verwendet, es sei denn, es ist explizit etwas anderes erwähnt. Herausragende Eigenschaften von LEDs im Vergleich zu anderen, konventionellen Lichtquellen von Leuchtmitteln sind eine wesentlich längere Lebensdauer und eine wesentlich höhere Lichtausbeute bei gleicher Leistungsaufnahme. Dadurch und unter anderem auch wegen ihrer kompakteren Abmessungen können durch Verwendung von LEDs als Lichtquelle von Leuchtmitteln besonders kompakte Kraftfahrzeugleuchten verwirklicht werden, die an fast jede nur erdenkliche Einbausituation angepasst sein können.For example, come as a light source of bulbs for automotive lights, inter alia, due to their low power consumption increasingly LEDs are used. These consist of at least one light-emitting diode semiconductor chip, short LED chip, as well as at least one, for example, molded by injection molding, the at least one LED chip completely or partially enveloping primary optics. Also, automotive lights are known in which pure LED chips are used without molded primary optics. In the following, therefore, for the sake of simplicity, no distinction is made between light-emitting diode and LED chip and, instead, the term LED is used uniformly for both embodiments, unless explicitly stated otherwise. Outstanding properties of LEDs compared to other, conventional light sources of bulbs are a much longer life and a significantly higher light output with the same power consumption. As a result, and among other things also because of their more compact dimensions can be realized by using LEDs as a light source of light bulbs particularly compact automotive lights, which can be adapted to almost every imaginable installation situation.

Darüber hinaus können bei einer Kraftfahrzeugleuchte ein oder mehrere Lichtleiter vorgesehen sein, beispielsweise um eine gewünschte Lichtverteilung z.B. über die Lichtscheibe hinweg des von einer oder mehreren Lichtquellen ausgestrahlten Lichts zu erhalten.In addition, in a motor vehicle light, one or more optical fibers may be provided, for example to provide a desired light distribution e.g. across the lens of the light emitted by one or more light sources.

Ein Lichtleiter, in den Licht mindestens einer Lichtquelle an mindestens einer Lichteinkoppelfläche ein- und an mindestens einer von der Lichteinkoppelfläche verschiedenen Lichtauskoppelfläche wieder ausgekoppelt wird, kann dabei als ein separates Bauteil im Leuchteninnenraum beherbergt oder Teil eines Leuchtmittels sein.An optical waveguide in which light is coupled in at least one light source to at least one light coupling surface and coupled back to at least one light coupling surface that is different from the light coupling surface can be accommodated as a separate component in the interior of the luminaire or be part of a light source.

Beispielsweise kann ein Leuchtmittel einen oder mehrere Lichtleiter sowie eine oder mehrere, das von ihnen ausgestrahlte Licht zumindest zum Teil in den wenigstens einen Lichtleiter einkoppelnde Lichtquellen umfassen. Ein Lichtleiter eines solchen Leuchtmittels kann beispielsweise als Primäroptik einer oder mehrerer LEDs dienen bzw. als eine solche Primäroptik ausgebildet sein.By way of example, a luminous means may comprise one or more light guides and one or more light sources emitting light from them, at least in part into the light sources coupling in at least one light guide. An optical waveguide of such a luminous means can serve, for example, as a primary optic of one or more LEDs or be designed as such a primary optic.

Der Lichtleiter kann beispielsweise als stabförmiger oder flächiger, so genannter Flächenlichtleiter ausgebildet sein, mit einer auf seiner beispielsweise normal zur Hauptabstrahlrichtung einer Kraftfahrzeugleuchte orientierten Vorderseite angeordneten Lichtauskoppelfläche.The light guide may be formed, for example, as a rod-shaped or flat, so-called surface light guide, with a light output surface arranged on its front side oriented, for example, normal to the main emission direction of a motor vehicle light.

Sind ein oder mehrere Lichtleiter und eine oder mehrere Optikscheiben vorgesehen, so erfordert dies einen hohen Herstellungsaufwand mit der Folge hoher Kosten durch die hierfür erforderlichen Einrichtungen sowie Herstellungs- und Montageschritte. Ein besonders großer Nachteil ergibt sich durch den Umstand, einer begrenzten Anzahl von für die Herstellung von Licht- und Optikscheiben sowie von Lichtleitern beispielsweise vorgesehenen Spritzgießmaschinen an einer Fertigungsstätte. Die Benutzung jeder einzelnen Spritzgießmaschine stellt demnach einen erheblichen Kostenfaktor dar, da die entsprechende Spritzgießmaschine nicht für die Herstellung eines Bauteils für eine andere und/oder weitere Kraftfahrzeugleuchte zur Verfügung steht.If one or more optical waveguides and one or more optical disks are provided, this requires a high manufacturing outlay with the consequence of high costs due to the equipment required for this, as well as manufacturing and assembly steps. A particularly great disadvantage results from the fact, a limited number of for the production of light and optical disks and optical fibers, for example, provided injection molding machines at a manufacturing facility. The use of each individual injection molding machine therefore represents a considerable cost factor, since the corresponding injection molding machine is not available for the production of a component for another and / or further motor vehicle light.

Durch DE 10 2007 033 709 A1 ist bekannt, dass eine Optikscheibe einer Kraftfahrzeugleuchte mit noppenförmigen optischen Mitteln ausgestattet ist. Die noppenförmigen optischen Mittel sind in einer regelmäßigen Struktur auf der Optikscheibe angeordnet. Jedes noppenförmige optische Mittel weist einen zylindrischen Teil und ein diesen abschließendes Formflächenteil auf. Der zylindrische Teil dient als Lichtleiter und als Streukörper zugleich.By DE 10 2007 033 709 A1 It is known that an optical disc of a motor vehicle lamp is equipped with knob-shaped optical means. The knob-shaped optical means are arranged in a regular structure on the optical disk. Each knob-shaped optical means has a cylindrical Part and this final form surface part. The cylindrical part serves as a light guide and as a scattering body at the same time.

Nachteilig hieran sind die sowohl im ein- als auch im ausgeschalteten Zustand der Kraftfahrzeugleuchte punktförmig sichtbaren Noppen. Dadurch vermittelt die Kraftfahrzeugleuchte einen verminderten Qualitätseindruck und eine verminderte optischen Güte. Darüber kann vermittels der Optikscheibe mit den Noppen nur eine Lichtfunktion verwirklicht werden.A disadvantage of this is the punctiform visible knobs both in the on and in the off state of the motor vehicle light. This gives the motor vehicle light a reduced quality impression and a reduced optical quality. In addition, only a light function can be realized by means of the optical disk with the knobs.

Durch DE 10 2007 033 709 A1 ist eine Kraftfahrzeugleuchte für einen Griff eines Kraftfahrzeugs bekannt. Die Lichtscheibe der Kraftfahrzeugleuchte ist als Lichtleiter ausgebildet.By DE 10 2007 033 709 A1 a motor vehicle lamp for a handle of a motor vehicle is known. The lens of the motor vehicle light is designed as a light guide.

Nachteilig hieran ist, dass der Lichtleiter einer hohen Verschmutzung ausgesetzt ist, was die optische Güte stark einschränkt. Darüber hinaus vermag die Kraftfahrzeugleuchte lediglich eine Lichtfunktion zu erfüllen.The disadvantage of this is that the light guide is exposed to high pollution, which severely limits the optical quality. In addition, the vehicle light can only fulfill a lighting function.

Der Erfindung liegt die Aufgabe zu Grunde, eine Kraftfahrzeugleuchte zu entwickeln, die kostengünstig herstellbar ist und eine hohe optische Güte bei gleichzeitig hohem Qualitätseindruck aufweist. Darüber hinaus ist es wünschenswert, dass die Kraftfahrzeugleuchte mehrere Lichtfunktionen erfüllen kann.The invention is based on the object to develop a motor vehicle light that is inexpensive to produce and has a high optical quality with high quality impression. In addition, it is desirable that the automotive lamp can perform multiple light functions.

Die Aufgabe wird gelöst mit den Merkmalen des unabhängigen Anspruchs.The object is solved with the features of the independent claim.

Demnach ist eine Kraftfahrzeugleuchte vorgesehen, mit einem von einer Lichtscheibe und einem Leuchtengehäuse umschlossenen Innenraum. In dem Leuchteninnenraum ist zumindest ein Leuchtmittel mit wenigstens einer Lichtquelle beherbergt. Das mindestens eine Leuchtmittel dient der Erfüllung wenigstens einer Lichtfunktion der Kraftfahrzeugleuchte. In dem Leuchteninnenraum kann darüber hinaus wenigstens ein zumindest einem Leuchtmittel oder einer oder mehreren Lichtquellen eines oder mehrerer Leuchtmittel zugeordneter Reflektor beherbergt sein. Ebenfalls ist denkbar, dass zumindest ein Reflektor durch das Leuchtengehäuse selbst gebildet wird. Beispielsweise kann das Leuchtengehäuse hierzu zumindest stellenweise mit einer reflektierenden Beschichtung versehen sein. Ebenfalls ist denkbar, hierzu das Leuchtengehäuse zumindest zum Teil aus einem vorzugsweise hellen, reflektierenden Material herzustellen, z.B. aus weißem Kunststoff wenigstens in dem Bereich mit Reflektorfunktion.Accordingly, a motor vehicle light is provided with an enclosed by a lens and a lamp housing interior. At least one light source with at least one light source is accommodated in the interior of the luminaire. The at least one light source serves to fulfill at least one light function of the motor vehicle light. In addition, at least one reflector assigned to at least one light source or one or more light sources of one or more light sources can be accommodated in the interior of the luminaire. It is also conceivable that at least one reflector is formed by the luminaire housing itself. For example, the luminaire housing can be provided at least in places with a reflective coating for this purpose. It is also conceivable for this purpose to produce the luminaire housing at least partly from a preferably bright, reflecting material, for example from white plastic, at least in the region with Reflector function.

Die Kraftfahrzeugleuchte zeichnet sich durch mindestens ein im Leuchteninnenraum beherbergtes Bauteil aus, das zumindest eine erste Partie aufweist, welche als wenigstens ein Lichtleiter mit entsprechenden Lichtleitereigenschaften ausgebildet ist, sowie mindestens eine zweite Partie aufweist, welche als wenigstens eine Optikscheibe mit entsprechenden Optikscheibeneigenschaften ausgebildet ist. Die mindestens zwei Partien sind vorzugsweise räumlich voneinander getrennt.The motor vehicle lamp is characterized by at least one component accommodated in the interior of the luminaire, which has at least one first section which is designed as at least one optical waveguide with corresponding optical waveguide properties, and has at least one second section, which is designed as at least one optical disk with corresponding optical disk properties. The at least two batches are preferably spatially separated.

Sich hierdurch ergebende Vorteile gegenüber dem Stand der Technik sind unter Anderem die Einsparung wenigstens eines Bauteils, verbunden mit dem Freiwerden zumindest einer Spritzgießmaschine einer begrenzten Anzahl von Spritzgießmaschinen einer Fertigungsstätte, sowie einer wesentlich zeitsparenderen und dadurch kostengünstigeren Montage einer nunmehr weniger Bauteile aufweisenden Kraftfahrzeugleuchte.The resulting advantages over the prior art include the saving of at least one component, associated with the freeing of at least one injection molding machine of a limited number of injection molding machines of a manufacturing facility, as well as a much more time-saving and thus more cost-effective installation of a now less components having motor vehicle light.

Die unterschiedlichen Partien können dabei unterschiedlichen Lichtfunktionen der Kraftfahrzeugleuchte zugeordnet sein. Ebenfalls ist denkbar, dass mehrere Partien gleichen Lichtfunktionen zugeordnet sind.The different lots can be assigned to different light functions of the motor vehicle light. It is also conceivable that several lots are assigned the same lighting functions.

Beispielsweise können die mindestens zwei Partien einer oder mehreren Lichtfunktionen derart zugeordnet sein, dass zumindest eine Partie zumindest zeitweilig einer anderen Lichtfunktion zugeordnet ist, als wenigstens eine verbleibende Partie. Beispielsweise können zwei oder mehr Partien einer Rücklichtfunktion zugeordnet sein. Dabei kann eine der Partien zusätzlich einer Bremslichtfunktion zugeordnet sein. Ebenfalls ist denkbar, dass unterschiedliche Partien generell unterschiedlichen Lichtfunktionen zugeordnet sind. So ist beispielsweise denkbar, dass z.B. mindestens eine Partie einer Wiederholblinklichtfunktion zugeordnet ist, wenigstens eine weitere Partie einer Bremslichtfunktion und zumindest eine andere Partie einer Rücklichtfunktion.For example, the at least two lots may be associated with one or more lighting functions such that at least one batch is at least temporarily associated with a different light function than at least one remaining batch. For example, two or more lots may be associated with a backlight function. In this case, one of the games can additionally be assigned to a brake light function. It is also conceivable that different games are generally assigned to different lighting functions. For example, it is conceivable that e.g. at least one lot is associated with a repeating flashing light function, at least one further batch of a brake light function and at least one other lot of a tail light function.

Die Kraftfahrzeugleuchte kann beispielsweise als Heckleuchte für ein Kraftfahrzeug ausgebildet sein.The motor vehicle light may be formed, for example, as a tail lamp for a motor vehicle.

Vorteile der Erfindung ergeben sich unter Anderem dadurch, dass das zumindest eine als Lichtleiter ausgebildete Partie und wenigstens eine als Optikscheibe ausgebildete Partie umfassende Bauteil vermittels einer einzigen Spritzgießmaschine hergestellt werden kann. Dadurch wird nur eine Spritzgießmaschine einer endlichen Anzahl von Spritzgießmaschinen einer Fertigungsstätte zur Herstellung wenigstens eines Lichtleiters und wenigstens einer Optikscheibe benötigt. Verbleibende Spritzgießmaschinen können für die Herstellung gleicher oder anderer Bauteile verwendet werden. Hierdurch wird eine kostengünstige Herstellung einer z.B. als Heckleuchte für Kraftfahrzeuge ausgebildeten Kraftfahrzeugleuchte ermöglicht. Darüber hinaus werden weniger kostspielige Spritzgießwerkzeuge benötigt. Außerdem wird durch die im Vergleich zum Stand der Technik verringerte Anzahl an Bauteilen eine weniger zeitaufwändige und dadurch weniger kostenintensive Montage der Kraftfahrzeugleuchte ermöglicht.Advantages of the invention result inter alia from the fact that the at least one formed as a light conductor lot and at least one formed as an optical disc lot comprehensive component by means of a single injection molding machine can be produced. As a result, only one injection molding machine of a finite number of injection molding machines of a production facility is required for producing at least one optical waveguide and at least one optical disk. Remaining injection molding machines can be used for the production of the same or other components. As a result, a cost-effective production of an example designed as a taillight for motor vehicles motor vehicle light is made possible. In addition, less expensive injection molding tools are needed. In addition, a less time-consuming and thus less expensive installation of the motor vehicle light is made possible by the reduced number of components compared to the prior art.

Die Erfindung behebt so unter Anderem das Problem, wonach bislang bei z.B. als Heckleuchten ausgebildeten Kraftfahrzeugleuchten, bei denen zur Erzeugung z.B. einer gewünschten Abstrahlcharakteristik mindestens einer bestimmten Lichtfunktion sowohl Lichtleiter als auch Optikscheiben vorgesehen sind, Lichtleiter und Optikscheiben als getrennte Bauteile hergestellt werden. Durch die Verwendung eines Bauteils, das voneinander getrennte, als Lichtleiter und als Optikscheibe ausgebildete Partien mit entsprechenden jeweiligen Eigenschaften aufweist, wird auf einfach herstellbare Weise ein hoher Qualitätseindruck einhergehend mit einer hohen optischen Güte der Kraftfahrzeugleuchte erreicht. Durch die Verringerung der Anzahl der benötigten Bauteile können im Vergleich zum Stand der Technik außerdem geringere Herstellungs- und Montagekosten erzielt werden.The invention thus solves, among other things, the problem whereby hitherto, e.g. Automotive vehicle lamps in the form of taillights, in which a desired radiation characteristic of at least one specific light function both optical fiber and optical disks are provided, optical fibers and optical disks are produced as separate components. By using a component which has separate, designed as a light guide and as an optical disc games with corresponding respective properties, a high quality impression is achieved in a simple manner producible with a high optical quality of the motor vehicle lamp. By reducing the number of components required, in addition, lower manufacturing and assembly costs can be achieved compared to the prior art.

Die Erfindung wird nachfolgend anhand von in der Zeichnung dargestellten Ausführungsbeispielen näher erläutert. Darin bezeichnen gleiche Bezugszeichen gleiche oder gleich wirkende Elemente.The invention will be explained in more detail with reference to embodiments shown in the drawing. Therein, like reference characters designate like or equivalent elements.

Die einzige Fig. 1 zeigt in schematischer Darstellung eine Draufsicht auf ein Bauteil mit zumindest zwei voneinander räumlich getrennten Partien, mindestens einer ersten, als Lichtleiter ausgebildeten Partie mit entsprechenden Lichtleitereigenschaften, und zumindest einer zweiten, als Optikscheibe ausgebildeten Partie mit entsprechenden Optikscheibeneigenschaften.The only Fig. 1 shows a schematic representation of a plan view of a component with at least two mutually spatially separate parts, at least a first, designed as a light guide lot with corresponding light guide properties, and at least a second, designed as an optical disc lot with corresponding optical disc properties.

Ein in Fig. 1 dargestelltes Bauteil 01 ist zum Einbau in eine nicht näher dargestellte Kraftfahrzeugleuchte vorgesehen. Die Kraftfahrzeugleuchte weist vorzugsweise einen durch ein Leuchtengehäuse und eine dieses abschließende Lichtscheibe umschlossenen Leuchteninnenraum auf. Der Leuchteninnenraum beherbergt zumindest ein Leuchtmittel mit wenigstens einer Lichtquelle zur Erfüllung mindestens einer Lichtfunktion der Kraftfahrzeugleuchte. Als Lichtquelle kommen bevorzugt eine oder mehrere LEDs zum Einsatz. Es können z.B. für unterschiedliche Lichtfunktionen auch unterschiedliche Lichtquellen zum Einsatz kommen.An in Fig. 1 illustrated component 01 is provided for installation in a motor vehicle light, not shown. The motor vehicle lamp preferably has a through a lamp housing and this final Lens enclosed lamp interior. The lamp interior accommodates at least one light source with at least one light source to fulfill at least one light function of the motor vehicle light. As the light source preferably one or more LEDs are used. For example, different light sources can also be used for different light functions.

Das Bauteil 01 weist mindestens zwei unterschiedlichen Partien 02, 03, 04, 05 auf. Zumindest eine erste Partie 02, 04 ist als wenigstens ein Lichtleiter 06 mit entsprechenden Lichtleitereigenschaften ausgebildet. Mindestens eine zweite Partie 03, 05 ist als wenigstens eine Optikscheibe 07 mit entsprechenden Optikscheibeneigenschaften ausgebildet.The component 01 has at least two different parts 02, 03, 04, 05. At least one first batch 02, 04 is designed as at least one light guide 06 with corresponding optical fiber properties. At least one second section 03, 05 is designed as at least one optical disk 07 with corresponding optical disk properties.

Zumindest zwei unterschiedliche Partien 02, 03, 04, 05 können wenigstens zeitweise mindestens zwei unterschiedlichen Lichtfunktionen der Kraftfahrzeugleuchte zugeordnet sein. Alternativ oder zusätzlich können mehrere Partien gleichen Lichtfunktionen der Kraftfahrzeugleuchte zugeordnet sein und/oder es können unterschiedliche Partien unterschiedlichen Lichtfunktionen der Kraftfahrzeugleuchte zugeordnet sein.At least two different parts 02, 03, 04, 05 can be assigned to at least two different light functions of the motor vehicle light at least temporarily. Alternatively or additionally, a plurality of batches may be assigned to the same lighting functions of the motor vehicle light and / or different batches may be assigned to different lighting functions of the motor vehicle light.

Beispielsweise können alle Partien 02, 03, 04, 05 einer Rücklichtfunktion zugeordnet sein. Zusätzlich kann zumindest die Partie 03, gegebenenfalls zusätzlich die Partie 02 und die Partie 04 einer Bremslichtfunktion zugeordnet sein. Ebenfalls ist denkbar, dass die Partie 02 und die Partie 04 einer Hintergrundbeleuchtung z.B. als Rücklichtfunktion der Kraftfahrzeugleuchte zugeordnet sind, die Partie 03 ausschließlich einer Bremslichtfunktion zugeordnet ist und die Partie 05 ausschließlich einer Seitenmarkierungslichtfunktion zugeordnet ist.For example, all games 02, 03, 04, 05 can be assigned to a taillight function. In addition, at least the lot 03, optionally in addition the lot 02 and the lot 04 can be assigned to a brake light function. It is also conceivable that the portion 02 and the portion 04 of a backlight, e.g. are assigned as a taillight function of the motor vehicle light, the lot 03 is assigned exclusively to a brake light function and the lot 05 is assigned exclusively to a side marker light function.

Zumindest zwei der mindestens zwei Partien 02, 03, 04, 05 können räumlich voneinander getrennt sein. Die räumliche Trennung kann beispielsweise durch einen oder mehrere Verbindungsstege 08, 09 verwirklicht bzw. hergestellt sein.At least two of the at least two parts 02, 03, 04, 05 can be spatially separated from one another. The spatial separation can be realized or produced, for example, by one or more connecting webs 08, 09.

Alternativ oder zusätzlich können zumindest zwei unterschiedliche Partien 02, 03, 04, 05 bzw. mindestens zwei Partien 02, 03, 04, 05 aneinander angrenzen.Alternatively or additionally, at least two different parts 02, 03, 04, 05 or at least two parts 02, 03, 04, 05 adjoin one another.

Bei dem in Fig. 1 dargestellten Bauteil 01 grenzen beispielsweise die Partien 02, 04 unmittelbar aneinander an, wohingegen die Partien 03 und 05 räumlich voneinander getrennt sind, die Partie 03 von den Partien 02, 04 durch die Stege 08 räumlich getrennt ist und die Partie 05 von den Partien 02, 04 durch die Stege 09 räumlich getrennt ist.At the in Fig. 1 represented component 01, for example, the games 02, 04 directly adjacent to each other, whereas the games 03 and 05 spatially from each other are separated, the lot 03 of the games 02, 04 is spatially separated by the webs 08 and the lot 05 is spatially separated from the games 02, 04 by the webs 09.

Die als Lichtleiter 06 ausgebildeten Partien 02, 04 können die als Optikscheibe 07 ausgebildeten Partien 03, 05 wie bei dem in Fig. 1 dargestellten Bauteil 01 zumindest zum Teil einrahmen bzw. umgeben. Auch ist denkbar, dass eine oder mehrere als Optikscheiben 07 ausgeführte Partien 03, 05 eine oder mehrere als Lichtleiter 06 ausgebildete Partien 02, 04 zumindest teilweise einrahmen bzw. umgeben. Auch Kombinationen hiervon sind denkbar.The formed as a light guide 06 games 02, 04 can be formed as optical disk 07 games 03, 05 as in the in Fig. 1 Part 01 frame at least partially framed or surrounded. It is also conceivable for one or more parts 03, 05 designed as optical disks 07 to at least partially frame or surround one or more parts 02, 04 designed as optical fibers 06. Also combinations of these are conceivable.

Wichtig ist hervorzuheben, dass die Erfindung auch durch ein Bauteil 01 verwirklicht sein kann, dass zum Einbau in einen Leuchteninnenraum einer Kraftfahrzeugleuchte vorgesehen ist. Das Bauteil 01 kennzeichnet sich durch wenigstens zwei unterschiedliche Partien 02, 03, 04, 05 aus, zumindest eine erste Partie 02, 04, welche als wenigstens ein Lichtleiter 06 mit entsprechenden Lichtleitereigenschaften ausgebildet ist, sowie mindestens eine zweite Partie 03, 05, welche als wenigstens eine Optikscheibe 07 mit entsprechenden Optikscheibeneigenschaften ausgebildet ist.It is important to emphasize that the invention can also be realized by a component 01 that is provided for installation in a lamp interior of a motor vehicle light. The component 01 is characterized by at least two different lots 02, 03, 04, 05, at least one first batch 02, 04, which is designed as at least one optical fiber 06 with corresponding optical fiber properties, and at least one second batch 03, 05, which as at least one optical disk 07 is formed with corresponding optical disk properties.

Die zumindest zwei unterschiedlichen Partien 02, 03, 04, 05 können dabei wenigstens zeitweise mindestens zwei unterschiedlichen Lichtfunktionen der Kraftfahrzeugleuchte zugeordnet sein. Alternativ oder zusätzlich können generell unterschiedliche Partien 02, 03, 04, 05 unterschiedlichen Lichtfunktionen der Kraftfahrzeugleuchte zugeordnet sein. Auch können mehrere Partien 02, 03, 04, 05 gleichen Lichtfunktionen der Kraftfahrzeugleuchte zugeordnet sein.The at least two different lots 02, 03, 04, 05 can be assigned to at least two different light functions of the motor vehicle light at least temporarily. Alternatively or additionally, generally different batches 02, 03, 04, 05 can be assigned to different light functions of the motor vehicle light. Also, multiple lots 02, 03, 04, 05 may be assigned to the same lighting functions of the motor vehicle light.

Zumindest zwei der mindestens zwei Partien 02, 03, 04, 05 können räumlich voneinander getrennt sein. Beispielsweise kann die räumliche Trennung durch mindestens einen Verbindungssteg 08, 09 hergestellt sein. Zumindest zwei unterschiedliche Partien 02, 03, 04, 05 bzw. mindestens zwei Partien 02, 03, 04, 05 können aneinander angrenzen.At least two of the at least two parts 02, 03, 04, 05 can be spatially separated from one another. For example, the spatial separation can be made by at least one connecting web 08, 09. At least two different lots 02, 03, 04, 05 or at least two lots 02, 03, 04, 05 can adjoin one another.

Besonders wichtig ist hervorzuheben, dass das Bauteil bevorzugt aus einem transparenten Werkstoff beispielsweise durch Spritzgießen hergestellt ist. Der Werkstoff ist dabei vorzugsweise identisch für alle Partien 02, 03, 04, 05 des Bauteils 01, sowie für die gegebenenfalls vorgesehenen, zumindest zwei Partien 02, 03, 04, 05 gegebenenfalls räumlich trennenden Stege 08, 09. Grundsätzlich ist auch ein zwei- oder mehrstufiger Spritzgießvorgang denkbar, bei dem z.B. für die mindestens eine als Lichtleiter 06 ausgebildete Partie 02, 04 ein anderer Werkstoff zum Einsatz kommt, als z.B. für die mindestens eine als Optikscheibe 07 ausgebildete Partie 03, 05. Die Stege 08, 09 können dabei aus dem selben Werkstoff, wie die mindestens eine als Lichtleiter 06 ausgebildete Partie 02, 04 oder die mindestens eine als Optikscheibe 07 ausgebildete Partie 03, 05 hergestellt sein.It is particularly important to emphasize that the component is preferably made of a transparent material, for example by injection molding. The material is preferably identical for all lots 02, 03, 04, 05 of the component 01, as well as for the optionally provided, at least two lots 02, 03, 04, 05 optionally spatially separating bars 08, 09. Basically, a two- or multi-level Injection molding process conceivable in which, for example, for the at least one formed as a light guide 06 batch 02, 04, a different material is used, for example, for the at least one formed as optical disk 07 lot 03, 05. The webs 08, 09 can thereby from the same Material, such as the at least one formed as a light guide 06 lot 02, 04 or the at least one formed as optical disk 07 lot 03, 05 be made.

Die Erfindung ist insbesondere im Bereich der Herstellung von Kraftfahrzeugleuchten gewerblich anwendbar.The invention is particularly industrially applicable in the field of production of motor vehicle lights.
