Description

Die Erfindung betrifft ein Lichtfenster für Signalleuchten, insbesondere für Blinker in Außenspiegeln unter Verwendung von optischer Folie und Lichtleitertechnik.The invention relates to a light window for signal lights, in particular for turn signals in exterior mirrors using optical film and optical fiber technology.

Stand der TechnikState of the art

Aus dem Stand der Technik sind unterschiedliche Ausbildungen von Blinkern in Außenspiegeln bekannt. Diese Zusatzblinker, die bisher nicht durch gesetzliche Regelungen vorgeschrieben sind, erfüllen dabei einen Sicherheitsfunktion und werten das Fahrzeug nach ästhetischen Gesichtspunkten auf. Für die Spiegelblinker werden LEDs eingesetzt und im zunehmenden Maßen Lichtleiterstrukturen aus Plexiglas.Different designs of turn signals in exterior mirrors are known from the prior art. These additional turn signals, which are not yet prescribed by statutory regulations, thereby fulfill a safety function and upgrade the vehicle according to aesthetic considerations. LEDs are used for the mirror indicators and, to an increasing extent, light guide structures made of Plexiglas.

Aus der US7255464 sind dazu einen Vielzahl unterschiedlicher Ausführungsformen publiziert. Die Spiegelblinker werden dabei aus mehreren Bauteilen zusammengesetzt: ein Gehäuse wird von einem Lichtfenster verschlossen, ein zusätzlicher Lichtleiter kann vorhanden sein, es werden LEDs auf Leiterplatten verbaut.From the US7255464 are published to a variety of different embodiments. The mirror indicators are composed of several components: a housing is closed by a light window, an additional light guide can be present, LEDs are mounted on printed circuit boards.

Dabei sollen die Herstellungskosten aber gering bleiben. Auch die Herstellungsprozesse sollen möglichst einfach gestaltet sein und so qualitativ hochwertige Produkte erzeugen. Dabei hat es sich herausgestellt, dass die Herstellung der Lichtfenster, die als Lichtleiter dienen, wie in der EP0858932 beschreiben, nicht einfach ist. Die Lichtfenster dienen als Lichtleiter für den Transport des Lichtes von der Einkoppelstelle des Lichtes zu den Auskoppelstellen des Spiegelblinkers. Da die Spiegelblinker den gesetzlichen Vorgaben für die Leuchtdichte in einem definierten Abstrahlbereich genügen müssen, ist die Herstellung und das Anbringen der Auskoppelstellen nicht nur ein ästhetischer Prozess. Hier hat sich gezeigt, dass die Herstellung der Spritzgussformen für die Auskoppelstruktur ein Problem darstellt. Auskoppelstrukturen sollen zunehmend einen harmonischen Lichteindruck des Lichtfensters erzeugen, was nur durch sehr dichte und sehr feine Strukturen zu gewährleisten ist.However, the production costs should remain low. The manufacturing processes should be as simple as possible and thus produce high-quality products. It has been found that the production of the light windows, which serve as a light guide, as in the EP0858932 describe is not easy. The light windows serve as light guides for the transport of the light from the coupling point of the light to the coupling-out points of the mirror turn signal. Since the mirror indicators must meet the legal requirements for the luminance in a defined radiation range, the production and installation of the decoupling is not only an aesthetic process. Here it has been shown that the production of injection molds for the coupling-out structure is a problem. Decoupling structures should increasingly produce a harmonious light impression of the light window, which can only be ensured by very dense and very fine structures.

Dadurch werden Die Spritzgusswerkzeuge aufwendiger und kostenintensiver.As a result, the injection molding tools are more complicated and cost-intensive.

Der Erfindung liegt die Aufgabe zugrunde, ein Lichtfenster dieser Art so auszubilden, dass es auf einfachen Spritzguss-Maschinen mit geringem Aufwand kostengünstig hergestellt werden kann.The invention has the object of providing a light window of this type so that it can be inexpensively manufactured on simple injection molding machines with little effort.

Diese Aufgabe wird bei einem Lichtfenster der gattungsbildenden Art erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruches 1 gelöst. Durch die Verwendung der optischen Folie sind zur Herstellung des Lichtfensters keine komplizierten Spritzgießformen erforderlich.This object is achieved in a light window of the generic type according to the invention with the characterizing features of claim 1. The use of the optical film does not require complicated injection molds to produce the light window.

Das erfindungsgemäße Lichtfenster kann in einem Takt und in nur einer Spritzgießform auf einfachen Maschinen mit geringem Arbeits- und Zeitaufwand kostengünstig hergestellt werden. Die Verwendung der optischen Folie hat den Vorteil, dass diese an die jeweilige Form des Lichtfensters einfach angepasst werden kann. Ferner ist es möglich, in die Folie Eigenschaften wie Farbränder, Kratzfestigkeits- und Beständigkeitsbeschichtungen, metallisierte Bereiche, Beschriftungen und dergleichen zu integrieren, so dass zusätzliche Veredelungsverfahren überflüssig sind. Zur Herstellung des Lichtfensters wird die Folie in die Spritzgießform eingelegt und der restliche Kunststoff angespritzt. Dabei wird glasklarer, kostengünstiger Kunststoff wie Polycarbonat oder PMMA zur Herstellung des erfindungsgemäßen Lichtfensters verwendet.The light window according to the invention can be produced inexpensively in a cycle and in only one injection mold on simple machines with low labor and time. The use of the optical film has the advantage that it can be easily adapted to the particular shape of the light window. Further, it is possible to incorporate into the film properties such as color edges, scratch resistance and resistance coatings, metallized areas, lettering and the like, so that additional finishing processes are superfluous. To produce the light window, the film is inserted into the injection mold and the remaining plastic molded. In this case, crystal clear, inexpensive plastic such as polycarbonate or PMMA is used for the production of the light window according to the invention.

Weitere Merkmale der Erfindung ergeben sich aus den weiteren Ansprüchen, der Beschreibung und den Zeichnungen,Further features of the invention will become apparent from the further claims, the description and the drawings,

Das Lichtfenster 1 nach den 1 ist für einen Spiegelblinker also für einen Signalgeber in einem Außenrückblickspiegel vorgesehen. Es besteht aus transparentem glasklaren Kunststoff und wird in einer Kunststoff-Spritzform durch Spritzgießen hergestellt. Das Lichtfenster 1 weist eine Einkoppelseite 10 und eine Auskoppelseite 11 auf, die aus einem stark strukturierten Anteil des Lichtfensters besteht. In der gewählten Ausführungsform ist die Auskopplung durch Nuten und Erhebungen auf der Außenseite des Lichtfensters 1 realisiert, wobei die Richtung der Nuten und der Erhebungen senkrecht zum Längsverlauf des Lichtfensters liegen. Dieser Längsverlauf erstreckt sich in etwa entlang einer x Achse von Fahrzeug selbst weg. Die z-Achse kennzeichnet die Fahrtrichtung des Fahrzeugs, die y-Achse die Erstreckung des Fahrzeugs über der Straßenebene. Das Lichtfenster 1 weist in dieser Ausführungsform einen Mittelteil auf, der oben und unten in y-Achsen-Richtung gesehen von Armbereichen 4 umgeben ist.The light window 1 after the 1 is therefore provided for a mirror indicator for a signal generator in an exterior rearview mirror. It consists of transparent clear plastic and is produced in a plastic injection mold by injection molding. The light window 1 has a Einkoppelseite 10 and a decoupling side 11 on, which consists of a highly structured portion of the light window. In the selected embodiment, the extraction by grooves and ridges on the outside of the light window 1 realized, wherein the direction of the grooves and the elevations are perpendicular to the longitudinal course of the light window. This longitudinal course extends approximately along an x axis away from the vehicle itself. The z-axis indicates the direction of travel of the vehicle, the y-axis the extent of the vehicle above the road level. The light window 1 In this embodiment, it has a central portion, which is seen from the top and bottom in y-axis direction of arm portions 4 is surrounded.

Um einen Spiegelblinker herzustellen wird das Lichtfenster 1 mit einem Blinkergehäuse verbunden. Die Verbindung ist im allgemeinen feuchtigkeitsfest und schließt einen Bauraum ein, in dem die Leuchtmittel, eine oder mehrerer LEDs, sowie eine oder mehrere Leiterplatten, metallisierte Bereiche zur Ausbildung von Reflektoren und Lichtleiterstrukturen, die mit dem Lichtfenster verbunden sind oder nicht, vorhanden sind.To create a mirror turn signal becomes the light window 1 connected to a turn signal housing. The joint is generally moisture resistant and includes space in which the bulbs, one or more LEDs, and one or more circuit boards, metallized areas for forming reflectors and light guide structures connected to the light window or not, are present.

Das erfindungsgemäße Lichtfenster ist aber nicht auf einen Spiegelblinker beschränkt und auch nicht auf einen Blinker im modularen Aufbau. Die Erfindung beschreibt eine Lichtscheibe, die in vorteilhafter Weise in einem In-Mould-Verfahren hergestellt wird.However, the light window according to the invention is not limited to a mirror indicator and not on a turn signal in the modular design. The invention describes a lens, which is advantageously produced in an in-mold process.

2 zeigt einen Schnitt senkrecht zur Erstreckungsachse x des Spiegelblinkers, der im Allgemeinen der Außenkontur des Außenspiegels angepasst ist und daher eine geschwungene Form aufweist. Die Lichtscheibe 1 hat in diesem Ausführungsbeispiel den ungefähren Querschnitt eines Parallelogramms. Zur Befestigung im Gehäuse des Außenspiegels und zur Verbindung mit dem Blinkergehäuse sind an die Lichtscheibe hakenförmige Armbereiche 4 angespritzt. Die innere Seite der Lichtscheibe 1 verläuft im Blinkergehäuse und im Gehäuse des Außenrückblickspiegels, die äußere Seite der Lichtscheibe 6 verlauft sichtbar entlang der Außenkontur des Außenspiegels. Die erfindungsgemäße Lösung sieht eine optische Folie 3 vor, die mindestens die äußere Fläche 6 des Lichtfensters bedeckt. Dabei wird in diesem Beispiel nicht nur die Oberfläche 6 der Lichtscheibe, sondern auch mindestens ein Teil der Flanken 8 von der Folie bedeckt. 2 shows a section perpendicular to the extension axis x of the mirror indicator, which is generally adapted to the outer contour of the exterior mirror and therefore has a curved shape. The lens 1 in this embodiment has the approximate cross section of a parallelogram. For attachment in the housing of the exterior mirror and for connection to the turn signal housing hook-shaped arm portions are on the lens 4 molded. The inner side of the lens 1 runs in the turn signal housing and in the housing of the exterior rearview mirror, the outer side of the lens 6 visibly runs along the outer contour of the exterior mirror. The solution according to the invention provides an optical film 3 at least the outer surface 6 covered by the light window. In this example, not only is the surface 6 the lens, but also at least part of the flanks 8th covered by the foil.

In alternativen Ausführungsformen wird die Folie 3 lediglich auf eine von außen sichtbare Fläche der Lichtscheibe begrenzt eingebracht.In alternative embodiments, the film becomes 3 only limited to an externally visible surface of the lens introduced limited.

Alternative zu dem Aufbringen der Folie auf einen Außenfläche des Lichtleiters wird die Folie auch umspritzt und liegt im Lichtleiter selbst.As an alternative to applying the film to an outer surface of the light guide, the film is also encapsulated and lies in the light guide itself.

Beispiele für optische Folien sind auf dem Markt erhältlich: beispielsweise lässt sich eine Extrusionsfolie aus Polycarbonat (PC) sehr gut durch Stanzen, Prägen, Thermo- oder Kaltformen verarbeiten. Sie ist im Siebdruck- oder Offsetdruck-Verfahren ohne Schwierigkeiten bedruckbar und verfügt über eine sehr gute graphische Qualität für kontrastreiches Bedrucken.Examples of optical films are available on the market: for example, an extrusion film made of polycarbonate (PC) can be processed very well by stamping, embossing, thermoforming or cold forming. It can be printed on screen printing or offset printing without difficulty and has a very good graphic quality for high-contrast printing.

3 zeigt eine schematische Darstellung der strukturierten optischen Folie 3 die mit Auskoppeloptiken 9 versehen ist. Es handelt sich dabei um prismatische erhabene Strukturen der Folie, die entsprechend dem vorgegebenen Design angeordnet sind. Die Strukturen sind dabei als Erhebungen mit unterschiedlichen Formen ausgestaltet. Wie in der Zeichnung angedeutet befinden sich die Auskoppeloptiken 9 entweder an der nach außen zum Betrachter gerichteten Seite der Folie 5 oder aber auf der Seite, die mit dem Material der Lichtscheibe überspritzt wird. 3 shows a schematic representation of the structured optical film 3 the with coupling optics 9 is provided. These are prismatic raised structures of the film, which are arranged according to the given design. The structures are designed as elevations with different shapes. As indicated in the drawing, the coupling-out optics are located 9 either on the side facing the viewer to the outside of the film 5 or on the side, which is over-injected with the material of the lens.

4a und b zeigt diese beiden Ausführungsformen. 4c zeigt eine Auskoppeloptik, die als Nuten senkrecht zur Längsausdehnung der optischen Folie 3 in der Folie eingeprägt ist. Diese Ausführungsform wird ebenso wie in den Beispielen 4a und 4b gezeigt, mit dem Material der Lichtscheibe überspritzt. 4a and b shows these two embodiments. 4c shows a coupling-out optics, which are grooves perpendicular to the longitudinal extent of the optical film 3 is imprinted in the film. This embodiment will be the same as in the examples 4a and 4b shown over-injected with the material of the lens.

Die Anordnung der Strukturen sowie deren Ausdehnung ist von dem gewünschten Auskoppeleffekt vorgegeben.The arrangement of the structures and their extent is determined by the desired coupling-out effect.

Die optische Folie 3 wird beim Spritzvorgang der Lichtscheibe 1 in die (nicht dargestellte) Spritzform eingelegt. Die Kontur der Folie 3 wird vorzugsweise an die Form der herzustellenden Lichtscheibe 1 angepasst. In die optische Folie 3 können zusätzliche Eigenschaften integriert werden, wie beispielsweise Farbränder, eine kratzfeste Beschichtung, Metallisierungen, Lackierungen, Beschriftungen oder Farbpigmentierungen, um den Blinker im unbeleuchteten Zustand an die Farbe des Spiegels anzupassen.The optical film 3 becomes during the injection process of the lens 1 inserted in the (not shown) injection mold. The contour of the foil 3 is preferably to the shape of the lens to be produced 1 customized. In the optical film 3 For example, additional features such as color margins, a scratch-resistant coating, metallizations, finishes, lettering, or color pigmentation can be added to match the direction indicator to the color of the mirror in the unlit state.

Für die Herstellung des Lichtfensters 1 wird glasklares Basismaterial, alternative dazu farbiges lichtdurchlässiges Material, verwendet, das kostengünstig erhältlich ist. Insbesondere lässt sich das Lichtfenster 1 in einer einzigen Spritzform herstellen. Die optische Folie 3 ist vorzugsweise eine Polycarbonat-Folie, die die beschrieben dreidimensionale Struktur aufweist. Sie kann ohne weiteres auch komplex gestaltetet Formen und Konturen aufweisen. Die Folie 3 wird zur Herstellung des Lichtfensters 1 in die Spritzform eingelegt. Auf die Hohlformseite 5 der Folie 3 kann man eine Schutzschicht einspritzen, z. B. eine kratzfeste Beschichtung, eine Beständigkeitsbeschichtung und dergleichen. Auf die Kernseite der Folie 3 wird eine Beschichtung 10, die den lichtleitenden Bereich des Lichtfensters bildet gespritzt. Die Beschichtung besteht vorzugsweise aus glasklarem Kunststoff, wie beispielsweise Polycarbonat oder PMMA.For the production of the light window 1 Crystal clear base material, alternative to colored translucent material is used, which is available at low cost. In particular, the light window can be 1 in a single mold. The optical film 3 is preferably a polycarbonate film having the described three-dimensional structure. It can easily have complex shapes and contours. The foil 3 is used to make the light window 1 inserted in the injection mold. On the mold side 5 the foil 3 you can inject a protective layer, z. As a scratch-resistant coating, a resistance coating and the like. On the core side of the film 3 becomes a coating 10 , which forms the light-conducting area of the light window. The coating is preferably made of clear plastic, such as polycarbonate or PMMA.

Es ist ferner möglich, die Schutzschicht bereits an der Folie 3 vorzusehen, so dass in der Spritzform nur noch die Beschichtung angespritzt wird.It is also possible, the protective layer already on the film 3 provide so that only the coating is sprayed in the mold.

Nach Beendigung des Spritzvorganges kann das fertige Lichtfenster 1 der Spritzform entnommen werden. Die Folie 3 ist vollständig in den die Schutzschicht und die Beschichtung bildenden Kunststoff eingebettet. Für die Schutzschicht und die Beschichtung können unterschiedliche, aber auch gleiche oder gleichartige Kunststoffe eingesetzt werden. After completion of the injection process, the finished light window 1 the injection mold can be removed. The foil 3 is completely embedded in the protective layer and the coating forming plastic. For the protective layer and the coating different, but also the same or similar plastics can be used.

Die Vorverarbeitung der optischen Folie erlaubt es, die Strukturen, Beschriftungen, Farben usw. auf einer planen Folie mit Druckverfahren und/oder Laseretching zu realisieren. Die Folien sind Massenprodukte und stehen daher kostengünstig zur Verfügung. Durch die breite Varianz der Foliengestaltung erhält man zur Herstellung der Lichtscheibe neue Möglichkeiten, die interessante Designs und Ausführungen für den Kunden beinhalteten.The pre-processing of the optical film makes it possible to realize the structures, inscriptions, colors, etc. on a flat film with printing process and / or laseretching. The films are mass-produced and therefore available at low cost. Due to the wide variance of the film design, new possibilities for the production of the lens are obtained, which include interesting designs and designs for the customer.

Es ist beispielsweise einfach, wie in 5 gezeigt, ein Logo 11 auf die Folie zu prägen oder zu drucken. Weiterhin sind Farbanpassungen an die Lackfarbe des Fahrzeugs einfach realisierbar.It's easy, for example, as in 5 shown a logo 11 to emboss or print on the film. Furthermore, color adjustments to the paint color of the vehicle are easy to implement.

Einen Farbstreifen 12 ist exemplarisch angebracht. Er kann als Schattierung oder als metallisierende Schicht ausgebildet sein und den Gesamteindruck des Lichtfensters prägen.A color stripe 12 is appropriate as an example. It can be designed as a shading or as a metallizing layer and characterize the overall impression of the light window.
