Abstract

The lamp cover (4a) forms an optical conductor. A second light source (5) couples light into a side surface of the cover. The cover includes imperfections, e.g. grooves, bubbles, injection-molded prisms. They can be surface- or in-depth imperfections, optionally laser-induced. These scatter light coupled into the cover, into the passenger compartment interior. The first lamp is incandescent or fluorescent, the second comprises LEDs.

Description

Die vorliegende Erfindung betrifft eine Innenleuchte für ein Kraftfahrzeug, beinhaltend ein Gehäuse, eine innerhalb des Gehäuses angeordnete erste Lichtquelle, und einen Reflektor sowie eine das Gehäuse abschließende Lichtscheibe.The The present invention relates to an interior light for a motor vehicle, including a housing, one inside the case arranged first light source, and a reflector and a casing final Lens.

Solche Innenleuchten kommen insbesondere als Leseleuchten im Innenraum von Kraftfahrzeugen zur Anwendung. Zur Eigenbeleuchtung weisen bekannte Innenleuchten insbesondere stabförmige Lichtleiter auf, die entlang des Leuchtenkörpers oder um den Leuchtenkörper herum angeordnet sind.Such Interior lights come especially as reading lights in the interior of motor vehicles for use. For self-lighting have known Interior lights, in particular rod-shaped light guides on that along the lamp body or around the lamp body are arranged around.

Hierbei ist nachteilig, daß diese Lichtleiter als Zusatzelemente zum eigentlichen Leuchtenkörper vorgesehen sind und zudem, daß damit keine flächige Ausleuchtung des gesamten Leuchtenkörpers möglich ist.in this connection is disadvantageous that this Light guide provided as additional elements to the actual lamp body and, moreover, that with it no areal Illumination of the entire lamp body is possible.

Es stellte sich daher die Aufgabe, eine Innenleuchte für Kraftfahrzeuge zu schaffen, die einen besonders einfachen Aufbau aufweist und eine flächige Eigenbeleuchtung ermöglicht.It Therefore, set the task, an interior light for motor vehicles to create, which has a particularly simple structure and a flat self-lighting allows.

Diese Aufgabe wird erfindungsgemäß erstens dadurch gelöst, daß die Lichtscheibe einen Lichtleiter ausbildet, daß eine zweite Lichtquelle Licht in eine Seitenfläche der Lichtscheibe einkoppelt, und daß die Lichtscheibe Störstellen aufweist, die das durch die zweite Lichtquelle in die Lichtscheibe eingekoppelte Licht in den Innenraum des Kraftfahrzeugs streuen.These Task is according to the invention firstly solved by that the Lens forms a light guide that a second light source light in a side surface the lens is coupled, and that the lens impurities having that through the second light source in the lens scatter coupled light into the interior of the motor vehicle.

Die vorgenannte Aufgabe wird zweitens auch dadurch gelöst, daß der Reflektor einen Lichtleiter ausbildet, daß eine zweite Lichtquelle Licht in eine Seitenfläche des Reflektors einkoppelt, und daß der Reflektor Störstellen aufweist, die das durch die zweite Lichtquelle in den Reflektor eingekoppelte Licht in den Innenraum des Kraftfahrzeugs streuen.The The second object is also achieved by the fact that the reflector forms a light guide that a second light source couples light into a side surface of the reflector, and that the reflector impurity having that through the second light source in the reflector scatter coupled light into the interior of the motor vehicle.

Zwei Ausführungsbeispiele der erfindungsgemäßen Innenleuchte sind in den beiden Figuren dargestellt und werden im folgenden anhand der Zeichnung näher erläutert.Two embodiments the interior light according to the invention are shown in the two figures and are described below closer to the drawing explained.

Gemeinsam ist beiden Ausführungen der Aufbau bestehend aus jeweils einer Lichtscheibe (4a, 4b) und einem Reflektor (3a, 3b), die gemeinsam das Gehäuse (1) der Innenleuchte ausbilden. Selbstverständlich kann das Gehäuse (1) noch weitere Gehäuseteile aufweisen, die aber zur Beschreibung der Erfindung nicht wesentlich sind und daher in den schematischen Darstellungen der Figuren nicht gezeigt sind.Common to both versions of the structure consisting of a respective lens ( 4a . 4b ) and a reflector ( 3a . 3b ), which together the housing ( 1 ) of the interior light. Of course, the housing ( 1 ) have further housing parts, but which are not essential to the description of the invention and are therefore not shown in the schematic representations of the figures.

Zwischen der Lichtscheibe (4a, 4b) und dem Reflektor (3a, 3b) ist eine erste Lichtquelle (2) angeordnet, die vorzugsweise als Glühlampe oder als Leuchtstofflampe ausgebildet ist, und deren Licht unter Mitwirkung des Reflektors (3a, 3b) in den Fahrzeuginnenraum strahlt. Hierdurch kann die Innenleuchte beispielsweise als Leseleuchte genutzt werden.Between the lens ( 4a . 4b ) and the reflector ( 3a . 3b ) is a first light source ( 2 ), which is preferably formed as an incandescent lamp or as a fluorescent lamp, and whose light with the cooperation of the reflector ( 3a . 3b ) radiates into the vehicle interior. As a result, the interior light can be used for example as a reading light.

Die erfindungsgemäße Innenleuchte weist außerdem eine zweite Lichtquelle (5) auf, die eine geringere Lichtstärke als die erste Lichtquelle (2) aufweisen kann und die durch eine Glühlampe mit geringer Leistung oder besonders vorteilhaft auch als weiße oder farbige LED ausgebildet sein kann.The interior light according to the invention also has a second light source ( 5 ), which has a lower light intensity than the first light source ( 2 ) and which may be formed by an incandescent lamp with low power or particularly advantageously also as a white or colored LED.

Das Licht dieser zweiten Lichtquelle (5) wird in ein als Lichtleiter wirkendes Bauteil der Innenleuchte geleitet. Dies ist im Ausführungsbeispiel der 1 die Lichtscheibe (4a), im Ausführungsbeipiel der 2 dagegen der Reflektor (3b), der hier aus einem transparenten Material (Glas oder Kunststoff) gefertigt und an seiner Außenseite verspiegelt ist. Selbstverständlich kann bei einer erfindungsgemäßen Innenleuchte auch vorgesehen werden, sowohl den Reflektor als auch die Lichtscheibe als lichtleitendes Bauteil auszubilden.The light of this second light source ( 5 ) is passed in a acting as a light guide component of the interior light. This is in the embodiment of 1 the lens ( 4a ), in the Ausführungsbeipiel the 2 whereas the reflector ( 3b ), which is here made of a transparent material (glass or plastic) and is mirrored on its outside. Of course, in an interior light according to the invention can also be provided to form both the reflector and the lens as a light-conducting component.

In das transparente Material des lichtleitenden Bauteils (Lichtscheibe (4a) bzw. Reflektor (3b)) sind jeweils gezielt Störstellen (6a, 6b) eingebracht, an denen das von der zweiten Lichtquelle (5) eingekoppelte Licht in den Fahrzeuginnenraum gestreut wird. Hierdurch ergibt sich eine flächig leuchtende Lichtscheibe (4a) bzw. ein flächig leuchtender Reflektor (3b), wobei hier vorrangig nicht die Ausleuchtung der Leuchtenumgebung sondern die Eigenbeleuchtung der Innenleuchte, etwa als Orientierungslicht für den Fahrer, beabsichtigt ist.In the transparent material of the light-conducting component (lens ( 4a ) or reflector ( 3b )) are each targeted impurities ( 6a . 6b ), at which the from the second light source ( 5 ) coupled light is scattered in the vehicle interior. This results in a flat illuminated lens ( 4a ) or a surface luminous reflector ( 3b ), in which case not primarily the illumination of the lighting environment but the self-lighting of the interior light, such as orientation light for the driver, is intended.

Die zweite Lichtquelle (5) kann im Wechsel mit der als Hauptlichtquelle dienenden ersten Lichtquelle (2) oder auch unabhängig von der ersten Lichtquelle (2) eingeschaltet werden, wobei bei eingeschalteter erster Lichtquelle (2) die Lichtaussendung der zweiten Lichtquelle (5) einfach überstrahlt wird.The second light source ( 5 ) can be used alternately with the first light source serving as the main light source ( 2 ) or independently of the first light source ( 2 ) are switched on, wherein when the first light source ( 2 ) the light emission of the second light source ( 5 ) is simply outshined.

Die für die Streuung des in die Lichtscheibe (4a) oder den Reflektor (3b) eingekoppelten Lichts erforderlichen Störstellen (6) können auf verschiedene Weisen erzeugt werden, insbesondere durch eine Laseraktivierung, also eine gezielte Verletzung des Lichtleitermaterials durch Laserstrahlen, durch angeformte lichtleitende Elemente, wie zum Beispiel mittels Spritzgießtechnik an die Lichtleiteroberfläche angeformte kleine Prismen oder auch durch Aufbringen von Lackpunkten auf die Oberfläche der Lichtscheibe (4a) oder des Reflektors (3b), durch die das im Inneren des lichtleitenden Bauteils geführte Licht ausgekoppelt wird.The for the scattering of the lens ( 4a ) or the reflector ( 3b ) incoupled light ( 6 ) can be produced in various ways, in particular by a laser activation, ie a targeted violation of the optical fiber material by laser beams, by integrally formed light-conducting elements, such as by injection molding on the optical fiber surface formed small prisms or by applying paint dots on the surface of the lens ( 4a ) or the reflector ( 3b ), through which the light guided in the interior of the light-conducting component is coupled out.
