Abstract
Description
Die Erfindung betrifft eine Beleuchtungsvorrichtung für einen Fahrzeuginnenraum mit zumindest zwei Lichtquellen.The The invention relates to a lighting device for a Vehicle interior with at least two light sources.
Aus
der
Der Erfindung liegt die Aufgabe zugrunde, eine gegenüber dem Stand der Technik verbesserte Beleuchtungsvorrichtung für einen Fahrzeuginnenraum anzugeben.Of the Invention is based on the object, a relation to the Prior art improved lighting device for indicate a vehicle interior.
Die
Aufgabe wird erfindungsgemäß mit einer Beleuchtungsvorrichtung
gelöst, welche die im Anspruch 1 angegebenen Merkmale aufweist.The
Object is according to the invention with a lighting device
having dissolved, which has the features specified in
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.advantageous Embodiments of the invention are the subject of the dependent claims.
Die Beleuchtungsvorrichtung für einen Fahrzeuginnenraum umfasst zumindest zwei Lichtquellen.The Lighting device for a vehicle interior includes at least two light sources.
Erfindungsgemäß sind die Lichtquellen jeweils über eine Lichteintrittsfläche mit einem gemeinsamen Lichtleitelement gekoppelt, wobei die Lichteintrittsflächen derart voneinander beabstandet angeordnet sind, dass verschiedene Lichtfunktionen über eine Lichtaustrittsfläche des gemeinsamen Lichtleiteelements erzeugbar sind.According to the invention the light sources each have a light entrance surface coupled to a common light guide, wherein the light entry surfaces are spaced apart such that different Light functions via a light exit surface of the common light guiding element can be generated.
Daraus resultiert in vorteilhafter Weise, dass mittels der einen Beleuchtungsvorrichtung mehrere Ausleuchtungen im Fahrzeuginnenraum realisierbar sind. Daraus folgt wiederum, dass ein notwendiger Bauraum zur Realisierung der Lichtfunktionen minimiert ist, woraus insbesondere für den Fahrzeuginnenraum eine höhere gestalterische Freiheit bei der Anordnung und Ausbildung der Beleuchtungsvorrichtung resultiert. Auch resultiert aus der gemeinsamen Verwendung einer Beleuchtungsvorrichtung für mehrere Lichtfunktionen ein geringer Material- und Kostenaufwand.from that results in an advantageous manner that by means of a lighting device several illuminations in the vehicle interior can be realized. from that again follows that a necessary space for the realization of Light functions is minimized, resulting in particular for the vehicle interior a greater freedom of design resulting in the arrangement and design of the lighting device. Also results from the common use of a lighting device for several lighting functions a low material and Cost.
Insbesondere ist es mittels des Lichtleitelements möglich, auch bei der Verwendung von Leuchtdioden mit einem hohen Lichtstrom eine gleichmäßige Lichtverteilung ohne Blendung für Insassen des Fahrzeugs zu erzeugen. Unter dem Lichtstrom der Leuchtdioden wird hierbei eine vom menschlichen Auge wahrgenommene Helligkeit des von der Leuchtdiode ausgesendeten Lichts verstanden.Especially it is possible by means of the light guide, even at the use of light emitting diodes with a high luminous flux a uniform Light distribution without glare for occupants of the vehicle to create. Under the luminous flux of the LEDs is in this case a perceived by the human eye brightness of the Understood light emitting diode emitted light.
