Kartoval, wie es beispielsweise auch aus der
Aufgabe der vorliegenden Erfindung ist es daher, eine Leuchteinheit für Fahrzeuge derart weiterzubilden, dass eine kartovalartige Optikeinheit unter Vermeidung vorgenannter Nachteile insbesondere zur Erzeugung einer Signalfunktion bereitgestellt wird.task The present invention is therefore a lighting unit for vehicles in such a way that a kartovalartige optical unit under Avoiding the aforementioned disadvantages, in particular for generating a Signal function is provided.
Zur Lösung dieser Aufgabe ist die Erfindung in Verbindung mit dem Oberbegriff des Patentanspruchs 1 dadurch gekennzeichnet, dass sich randseitig des zentralen Linsenelementes mindestens eine lichtführende Seitenwand anschließt, die sich topfförmig in Lichtabstrahlrichtung erstreckt, dass ein durch einen vorderen Rand der Seitenwand gebildeter Öffnungsbereich von einer Lichtscheibe abgedeckt ist und dass das zentrale Linsenelement eine sich im Wesentlichen in Lichtabstrahlrichtung erstreckende Dicke aufweist, die kleiner ist als der lichte Abstand einer Vorderseite des zentralen Linsenelementes zu der Lichtscheibe.to solution This object is the invention in conjunction with the preamble of claim 1, characterized in that edge of the central lens element at least one light-guiding side wall connects, which is cup-shaped in the light emission direction that extends through a front Edge of the side wall formed opening area is covered by a lens and that the central lens element a substantially extending in the light emission direction Has thickness which is smaller than the clear distance of a front side of the central lens element to the lens.
Nach der Erfindung ist eine kartovalartige Optikeinheit vorgesehen, die aus einem zentralen Linsenelement, mindestens einer sich randseitig an dem Linsenelement anschließender Seitenwand und einer die vorderen Öffnungsfläche der Seitenwand abschließenden Lichtscheibe besteht. Vorteilhaft wird hierdurch eine kartovalartige Optikeinheit mit einem „quasi"-massiven Erscheinungsbild eines Kartovals geschaffen, das gegenüber einem herkömmlichen Kartoval eine geringere Masse aufweist. Hierdurch kann der für optische Systeme erforderliche Schütteltest bzw. die Temperatur-Wechsel-Prüfung einfacher erfüllt werden. Darüber hinaus kann der Herstellungsaufwand für die Optikeinheit reduziert werden, da das zentrale Linsenelement, die Seitenwand und die Lichtscheibe vergleichsweise dünne Wände aufweisen. Ferner können die Kompo nenten (zentrales Linsenelement, Seitenwand, Lichtscheibe) der kartovalartigen Optikeinheit in Abhängigkeit von der gewünschten Lichtverteilung beliebig gestaltet werden.To The invention provides a kartovalartige optical unit, which from a central lens element, at least one at the edge subsequent to the lens element Sidewall and a front opening surface of the side wall final lens consists. This advantageously makes a kartovalartige optical unit with a "quasi" massive appearance created a Kartovals, which compared to a conventional Kartoval has a lower mass. This allows the for optical Systems required shaking test or the temperature change test easier Fulfills become. About that In addition, the manufacturing cost of the optical unit can be reduced, since the central lens element, the side wall and the lens have comparatively thin walls. Furthermore, can the components (central lens element, side wall, lens) of the kartovalartigen optical unit depending on the desired Light distribution can be designed arbitrarily.
Vorzugsweise sind die Wandstärken bzw. die Dicke der Wände des zentralen Linsenelementes und/oder der Seitenwand und/oder der Lichtscheibe derart gewählt, dass der durch diese Komponenten der Optikeinheit eingeschlossene Hohlraum ein größeres Volumen hat als das durch die Wände der vorgenannten Komponenten gebildete Volumen. Nach der Erfindung wird ein Hohlraum innerhalb der kartovalartigen Optikeinheit gebildet, wobei durch Ausgestaltung der Komponenten der kartovalartigen Optikeinheit das Erscheinungsbild eines massiven Kartovals hervorgerufen wird. Vorteilhaft kann hierdurch ein gewünschter stilistischer Effekt eines Kartovals erzeugt werden, obwohl tatsächlich kein massives Kartoval vorgesehen ist.Preferably are the wall thicknesses or the thickness of the walls the central lens element and / or the side wall and / or the Lens selected in such a way that enclosed by these components of the optical unit Cavity a larger volume has that through the walls the volume of the aforementioned components. After the invention If a cavity is formed within the kartovalartigen optical unit, wherein by configuring the components of the kartovalartigen optical unit the appearance of a massive Kartovals is caused. This can advantageously a desired stylistic effect of a Kartoval, although in fact not a massive Kartoval is provided.
Nach einer bevorzugten Weiterbildung der Erfindung ist die Wandstärke bzw. Dicke des zentralen Linsenelementes wesentlich kleiner als die Länge der parallel zu der Abstrahlrichtung projektierten Seitenwand. Vorteilhaft wird hierdurch ein Hohlraum in der Optikeinheit gebildet, ohne dass der Charakter eines massiven Kartovals verloren geht. Innerhalb des zentralen Linsenelementes erfolgt keine Totalreflexion des eingekoppelten Lichtes.To a preferred embodiment of the invention, the wall thickness or Thickness of the central lens element is substantially smaller than the length of the side wall projected parallel to the emission direction. Advantageous This is a cavity in the optical unit is formed without that the character of a massive Kartovals is lost. Within the central lens element is no total reflection of the coupled Light.
Nach einer Weiterbildung der Erfindung weist die Dicke des zentralen Linsenelementes eine Größe auf, die im Bereich der Dicke der Seitenwand und/oder der Dicke der Lichtscheibe liegt. Vorteilhaft kann hierdurch eine Optikeinheit mit relativ gleichmäßigen dünnwandigen Komponenten erstellt werden.To a development of the invention, the thickness of the central Lens element one size, in the range of the thickness of the side wall and / or the thickness of the lens lies. Advantageously, thereby an optical unit with relative uniform thin-walled Components are created.
Nach einer Weiterbildung der Erfindung ist eine Vorderseite des zentralen Linsenelementes konvexförmig ausgebildet, mit gegebenenfalls mehreren Vor zugskrümmungslinien, so dass eine vorgegebene Lichtverteilung erzeugt wird. Beispielsweise kann die Optikeinheit zur Erzeugung einer Bremslichtfunktion mit einem horizontalen Öffnungswinkel von 90° und einem vertikalen Öffnungswinkel von 20° oder eine Blinklichtfunktion mit einem horizontalen Öffnungswinkel von 125° und einem vertikalen Öffnungswinkel von 20° eingesetzt werden.According to a development of the invention, a front side of the central lens element is kon vexförmig formed, optionally with several zugskrümmungslinien, so that a predetermined light distribution is generated. For example, the optical unit for generating a brake light function with a horizontal opening angle of 90 ° and a vertical opening angle of 20 ° or a flashing light function with a horizontal opening angle of 125 ° and a vertical opening angle of 20 ° can be used.
Nach einer Weiterbildung der Erfindung kann die Seitenwand eine Licht führende Funktion haben und unter Totalreflexion des eingekoppelten Lichtes an den Wandflächen das Licht vorzugsweise zur Seite hin auskoppeln.To a development of the invention, the side wall a light premier Have function and under total reflection of the injected light on the wall surfaces preferably decouple the light to the side.
Nach einer Weiterbildung der Erfindung kann die Seitenwand nicht – wie das zentrale Linsenelement glasklar – sondern aus einem eingefärbten Material bestehen. Beispielsweise kann die Seitenwand auch durchscheinen (transluszent) ausgebildet sein, so dass das Styling der kartovalartigen Optikeinheit den Designerfordernissen angepasst werden kann.To a development of the invention, the side wall is not - like that central lens element crystal clear - but of a colored material consist. For example, the side wall also shine through (transluszent) be formed, so that the styling of the kartovalartigen Optic unit can be adapted to the design requirements.
Nach einer Weiterbildung der Erfindung ist eine Mehrzahl von kartovalartigen Optikeinheiten schachbrettartig angeordnet, so dass eine Licht abgebende Fläche gebildet wird. Die Leuchteinheit weist somit einen modulhaften Charakter auf.To a development of the invention is a plurality of kartovalartigen Optics units arranged in a checkerboard pattern, allowing a light-emitting area is formed. The lighting unit thus has a modular character on.
