Abstract
Optikelement für eine Beleuchtungsvorrichtung in Fahrzeugen aus einem lichtdurchlässigen Kunststoffmaterial mit einem Linsenbereich, in dem eine Vorderseite und/oder eine Rückseite des Optikelementes gewölbt ausgebildet ist, und mit einem sich an den Linsenbereich anschließenden Nichtlinsenbereich, in dem die Vorderseite und die Rückseite des Optikelementes flach verlaufen, dadurch gekennzeichnet, dass der Nichtlinsenbereich (7) und/oder der Linsenbereich (3) eine Randkontur (8, 9) aufweisen, die mit einer Kontur (10) eines Gehäuseöffnungsrandes (11) übereinstimmt, in der das Optikelement (2) gelagert ist.Optical element for a lighting device in vehicles made of a translucent plastic material with a lens area in which a front and / or a rear of the optical element is curved, and with a non-lens area adjoining the lens area in which the front and the rear of the optical element run flat , characterized in that the non-lens region (7) and / or the lens region (3) have an edge contour (8, 9) which corresponds to a contour (10) of a housing opening edge (11) in which the optical element (2) is mounted ,
Description
Die Erfindung betrifft ein Optikelement für eine Beleuchtungsvorrichtung in Fahrzeugen aus einem lichtdurchlässigen Kunststoffmaterial mit einem Linsenbereich, in dem eine Vorderseite und/oder eine Rückseite des Optikelementes gewölbt ausgebildet ist, und mit einem sich an den Linsenbereich anschließenden Nichtlinsenbereich, in dem die Vorderseite und die Rückseite des Optikelementes flach verlaufen.The invention relates to an optical element for a lighting device in vehicles made of a translucent plastic material having a lens area in which a front and / or a back of the optical element is curved, and with a subsequent to the lens area non-lens area in which the front and the back of the optical element run flat.

Aufgabe der vorliegenden Erfindung ist es daher, ein Optikelement für eine Beleuchtungsvorrichtung in Fahrzeugen derart weiterzubilden, dass auf einfache Weise die in dem Scheinwerfer angeordneten lichttechnischen Bauteile für einen Betrachter von außen ein homogenes Erscheinungsbild ergeben, insbesondere eine Linse in ihrem Erscheinungsbild zurücktritt.Object of the present invention is therefore to develop an optical element for a lighting device in vehicles such that in a simple way arranged in the headlight lighting components for a viewer from the outside give a homogeneous appearance, in particular a lens recedes in appearance.
Zur Lösung dieser Aufgabe ist die Erfindung in Verbindung mit dem Oberbegriff des Schutzanspruchs 1, dadurch gekennzeichnet, dass der Nichtlinsenbereich und/oder der Linsenbereich eine Randkontur aufweisen, die mit einer Kontur eines Gehäuseöffnungsrandes übereinstimmt, in der das Optikelement gelagert ist.To achieve this object, the invention in conjunction with the preamble of claim 1 protection, characterized in that the non-lens area and / or the lens area have an edge contour which coincides with a contour of a housing opening edge in which the optical element is mounted.
Der besondere Vorteil der Erfindung besteht darin, dass durch seitliche Verlängerung eines Linsenbereiches in Erstreckungsrichtung desselben in Form eines Nichtlinsenbereiches eine Homogenisierung im Erscheinungsbild des Optikelementes eintritt. Grundgedanke der Erfindung ist es, eine Verflachung des im Wesentlichen eine Linsenfunktion zukommenden Optikelementes herbeizuführen, die das relativ massive Erscheinungsbild des Linsenbereiches aufgrund der Erstreckung in Lichtabstrahlrichtung zurückdrängt. Vorteilhaft kann der Nichtlinsenbereich insbesondere einer aus Designgründen vorgegebene Linienführung des Scheinwerfers nachfolgen.The particular advantage of the invention is that by lateral extension of a lens area in the direction of extension of the same occurs in the form of a non-lens area, a homogenization in the appearance of the optical element. The basic idea of the invention is to produce a flattening of the optical element which substantially corresponds to a lens function, which suppresses the relatively massive appearance of the lens area due to the extent in the light emission direction. Advantageously, the non-lens area can be followed, in particular, by a design of the headlight which is predetermined for design reasons.
Nach einer Weiterbildung der Erfindung weist eine im Linsen- und Nichtlinsenbereich verlaufenden Vorderseite des Optikelementes eine bogenförmige Form auf, so dass hierdurch ein einheitliches, homogenes Erscheinungsbild des Optikelementes verwirklicht wird.According to a development of the invention, a front side of the optical element extending in the lens and non-lens area has an arcuate shape, so that a uniform, homogeneous appearance of the optical element is thereby realized.
Weitere Vorteile der Erfindung ergeben sich aus den weiteren Unteransprüchen.Further advantages of the invention will become apparent from the further subclaims.
Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnungen näher erläutert.An embodiment of the invention will be explained in more detail with reference to the drawings.
