Abstract
Description
Die Erfindung betrifft eine Leuchteinheit für Kraftfahrzeuge mit einer Lichtquelle, mit einem der Lichtquelle zugeordneten Reflektor und mit einer eine vordere Öffnung des Reflektors abdeckenden Abdeckscheibe.The The invention relates to a lighting unit for motor vehicles with a Light source, with a light source associated with the reflector and with a front opening the reflector covering cover.
Aus
der
Aufgabe der vorliegenden Erfindung ist es, eine Leuchteinheit für Kraftfahrzeuge derart weiterzubilden, dass das von einer Lichtquelle ausgesandte Licht effektiver zur Bildung einer Lichtverteilung genutzt wird und ein modernes Aussehen der Leuchteinheit gewährleistet ist.task The present invention is a lighting unit for motor vehicles in such a way that emitted by a light source Light is used more effectively to form a light distribution and a modern appearance of the lighting unit is ensured.
Zur Lösung dieser Aufgabe ist die Erfindung in Verbindung mit dem Oberbegriff des Patentanspruchs 1 dadurch gekennzeichnet, dass zwischen dem Reflektor und der Abdeckscheibe eine Lichtscheibe angeordnet ist, die über einen koaxial zu der Lichtquelle verlaufenden zentralen Flächenabschnitt und über einen sich an denselben anschließenden äußeren Lichtleitabschnitt verfügt, wobei der äußere Lichtleitabschnitt eine Mehrzahl von Linsenelementen und denselben zugeordneten Klein-Reflektoren aufweist.to solution This object is the invention in conjunction with the preamble of the patent claim 1, characterized in that between the Reflector and the cover is arranged a lens, the above a coaxial with the light source extending central surface portion and over a to the same subsequent outer Lichtleitabschnitt features, wherein the outer light guide section a plurality of lens elements and the same associated small reflectors.
Der besondere Vorteil der Erfindung besteht darin, dass durch die Ausbildung einer zwischen einem Reflektor und einer Abdeckscheibe angeordneten Lichtscheibe bestehend aus einem zentralen Flächenabschnitt einerseits und einem äußeren Lichtleitabschnitt andererseits das gesamte von dem Reflektor reflektierte Licht zur Erzeugung einer vorgegebenen Lichtverteilung genutzt werden kann. Dabei bewirkt der Lichtleitabschnitt, der eine Mehrzahl von Linsenelementen und denselben zugeordneten Klein-Reflektoren aufweist, ein markantes Erscheinungsbild, weil es das Auftreten von mehreren Lichtemissionsquellen, wie beispielsweise Leuchtdioden, vorgibt.Of the particular advantage of the invention is that through the training one disposed between a reflector and a cover Lens consisting of a central surface portion on the one hand and an outer light guide section on the other hand, the entire light reflected from the reflector to Generation of a given light distribution can be used. In this case, the Lichtleitabschnitt, which causes a plurality of lens elements and the same associated small reflectors, a striking Appearance because it is the appearance of multiple light emission sources, such as LEDs, pretends.
Nach einer bevorzugten Ausführungsform der Erfindung ist der Lichtleitabschnitt kreisringförmig um den zentralen Flächenabschnitt angeordnet. Die Klein-Reflektoren sind jeweils rotationssymmetrisch zu dem Linsenelement angeordnet, so dass hierdurch das Erscheinungsbild von einer Mehrzahl von kreisförmig angeordneten Lichtquellen erzielt wird.To a preferred embodiment of Invention is the Lichtleitabschnitt circular around the central surface portion arranged. The small reflectors are each rotationally symmetric to arranged the lens element, so that thereby the appearance of a plurality of circular arranged light sources is achieved.
Nach einer Weiterbildung der Erfindung ist das Linsenelement als in Lichtaustrittsrichtung spitz zulaufender Prismenkörper ausgebildet mit einer ebenen Lichteinkoppelfläche und mit Schrägflächen als Lichtauskoppelfläche. Den Schrägflächen sind entsprechende Flächen des Klein-Reflektors zugeordnet, der vorzugsweise parabelförmig ausgebildet ist.To a development of the invention is the lens element as in the light exit direction pointed prism body formed with a flat light coupling surface and with inclined surfaces as Light coupling. The inclined surfaces are appropriate surfaces associated with the small reflector, which is preferably parabolic.
Der Klein-Reflektor ist einstückig mit dem zentralen Flächenabschnitt verbunden, wobei das Linsenelement von hinten in eine Öffnung des Klein-Reflektors eingesetzt und mit demselben durch Ultraschallschweißen verbunden ist. Die lotrecht zur optischen Achse der Leuchteinheit verlaufende Projektionsfläche der Lichtscheibe wird daher im Wesentlichen vollständig zur Erzeugung der vorgegebenen Lichtverteilung genutzt. Dabei kann durch unterschiedliche Taktung der vorzugsweise als Glühlampe ausgebildeten Lichtquelle oder durch Ansteuerung von zwei Glühwendeln unterschiedliche Lichtfunktionen, wie bei spielsweise Schlusslicht und Bremslicht einerseits und Schlusslicht und Nebellicht andererseits erzeugt werden. Vorzugsweise ist die Lichtscheibe entsprechend der zu erzielenden Lichtfunktion eingefärbt ausgestaltet.Of the Small reflector is one piece with the central surface section connected, wherein the lens element from the rear into an opening of the small reflector used and connected to the same by ultrasonic welding is. The perpendicular to the optical axis of the lighting unit running projection the lens is therefore substantially completely to Generation of the given light distribution used. It can by different timing of the preferably designed as a light bulb light source or by controlling two filaments different light functions, as for example tail light and brake light on the one hand and tail light and fog light, on the other hand. Preferably, the Lens designed colored according to the light function to be achieved.
Weitere Vorteile der Erfindung ergeben sich aus den weiteren Unteransprüchen.Further Advantages of the invention will become apparent from the other dependent claims.
Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnungen näher erläutert.One embodiment The invention will be explained in more detail with reference to the drawings.
