Abstract
Description
Die Erfindung betrifft eine Fahrzeugleuchtenanordnung mit einem Lichtleiter, der das Licht einer Lichtquelle zu einem, insbesondere zu beleuchtenden, Fahrzeugteil führt.The invention relates to a vehicle lamp arrangement with a light guide that converts the light from a light source into a leads in particular to the illuminated, vehicle part.
Um bewegliche Fahrzeugteile, wie z.B. eine Türgriffschale oder den Innenraum eines Aschers, zu beleuchten, wird das Licht einer Lichtquelle über Lichtleiter zum beweglichen Fahrzeugteil geführt. Als Lichtleiter wird dabei üblicherweise ein starres Kunststoff-Spritzgussteil mit aufwändig berechneter Lichtleitgeometrie oder aber ein Faserbündel aus vielen Glasfasern mit einem Durchmesser von je ca. 0,2 mm verwendet. Da aber das Faserbündel wegen der Bruchgefahr seiner Glasfasern nur sehr begrenzt gebogen werden kann, ist es z.B. für spitzwinklige Eckumlenkungen nicht geeignet.To movable vehicle parts, such as e.g. a door handle shell or to illuminate the interior of an ashtray becomes light a light source via light guide led to the moving vehicle part. Usually used as a light guide a rigid plastic injection molded part with an elaborately calculated light guide geometry or a bundle of fibers made of many glass fibers with a diameter of approx. 0.2 mm each. But since the fiber bundle bent only to a very limited extent due to the risk of breakage of its glass fibers can be e.g. For acute-angled corner deflections not suitable.
Der Erfindung liegt demgegenüber die Aufgabe zugrunde, eine Fahrzeugleuchtenanordnung der eingangs genannten Art dahingehend zu verbessern, dass der Lichtleiter mit möglichst kleinem Biegeradius umgebogen werden kann.The invention is in contrast Task based on a vehicle lamp assembly of the aforementioned Kind of improving that the light guide with as much as possible small bending radius can be bent.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Lichtleiter aus biegsamem durchsichtigem Kunststoff mit einer Dicke von mindestens 2 mm, vorzugsweise mindestens 3 mm, gebildet ist und dass der zulässige kleinstmögliche elastische Biegeradius des Lichtleiters höchstens fünfmal so groß wie seine Dicke ist.This object is achieved according to the invention solved, that the light guide made of flexible transparent plastic with a thickness of at least 2 mm, preferably at least 3 mm is and that the allowable smallest possible elastic bending radius of the light guide at most five times its size Thickness is.
Der zulässige kleinstmögliche elastische Biegeradius des Lichtleiters ist bevorzugt höchstens doppelt so groß wie seine Dicke, besonders bevorzugt kleiner als seine Dicke.The permissible smallest possible elastic bending radius the light guide is preferably at most double as big as its thickness, particularly preferably less than its thickness.
Der wesentliche Vorteil der erfindungsgemäßen Fahrzeugleuchtenanordnung besteht darin, dass der flexible biegsame Lichtleiter ohne plastische Verformung bzw. ohne Transmissionsänderung oder Materialschädigung elastisch verformbar ist und die Fahrzeugleuchtenanordnung daher am Beleuchtungsort praktisch keine Bautiefe benötigt.The main advantage of the vehicle lamp arrangement according to the invention is that the flexible, flexible light guide without plastic Deformation or elastic without transmission change or material damage is deformable and therefore the vehicle lamp arrangement at the lighting location practically no depth required.
Bei besonders bevorzugten Ausführungsformen der Erfindung ist der Lichtleiter ein Spritzgussteil, an dem dann auch andere Funktionsteile, wie z.B. Befestigungsteile, Dichtungen etc., angeformt sein können.In particularly preferred embodiments the invention, the light guide is an injection molded part, on which then also other functional parts, e.g. Fasteners, seals etc., can be molded.
Um Licht in den Lichtleiter möglichst effektiv einzukoppeln bzw. aus dem Lichtleiter möglichst effektiv auszukoppeln, können die Eintrittsfläche und/oder die Austrittsfläche des Lichtleiters als optische Mittel zur Änderung des Strahlengangs, z.B. als Linse, ausgebildet sein. Vorteilhaftennreise sind die Eintrittsfläche und/oder die Austrittsfläche des Lichtleiters durch eine Stirnseite des Lichtleiters gebildet.To light in the light guide as possible effectively coupling in or coupling out from the light guide as effectively as possible, can the entrance area and / or the exit surface the light guide as an optical means for changing the beam path, e.g. be designed as a lens. Advantageous travel are the entrance area and / or the exit surface of the light guide is formed by an end face of the light guide.
In einer vorteilhaften Ausführungsform der Erfindung ist der Lichtleiter bandförmig ausgebildet und beispielsweise aus glasklarem Silikon oder aus einem durchsichtigen Thermoplast-Elastomer (TPE) gebildet. Als Thermoplast-Elastomer ist beispielsweise „PTS-THERMOFLEX-60 *6000 hochtransparent" der Firma PLASTIC TECHNOLOGIE SERVICE Marketing- & Vertriebs-GmbH, D-91587 Adelshofen/Tauberzell geeignet.In an advantageous embodiment According to the invention, the light guide is band-shaped and, for example made of clear silicone or a transparent thermoplastic elastomer (TPE) formed. The thermoplastic elastomer is, for example, “PTS-THERMOFLEX-60 * 6000 highly transparent "from PLASTIC TECHNOLOGIE SERVICE Marketing- & Vertriebs-GmbH, D-91587 Adelshofen / Tauberzell.
Die erfindungsgemäße Fahrzeugleuchtenanordnung eignet sich besonders zur Beleuchtung von schwer zugänglichen Fahrzeugteilen (z.B. Türgriff) oder beweglich angeordneten Fahrzeugteilen, deren Bewegung der Lichtleiter aufgrund seiner Flexibilität ohne weiteres folgen kann.The vehicle lamp arrangement according to the invention is particularly suitable for illuminating difficult-to-access areas Vehicle parts (e.g. door handle) or movably arranged vehicle parts, the movement of the light guide due to its flexibility without more may follow.
Weitere Vorteile der Erfindung ergeben sich aus der Beschreibung und der Zeichnung. Ebenso können die vorstehend genannten und die noch weiter unten aufgeführten Merkmale erfindungsgemäß jeweils einzeln für sich oder zu mehreren in beliebigen Kombinationen Verwendung finden. Die gezeigte und beschriebene Ausführungsform ist nicht als abschließende Aufzählung zu verstehen, sondern hat vielmehr beispielhaften Charakter für die Schilderung der Erfindung.Further advantages of the invention result itself from the description and the drawing. Likewise, the above and the features listed below according to the invention in each case individually for one or more can be used in any combination. The embodiment shown and described is not to be considered as a conclusive list understand, but rather has exemplary character for the description of the Invention.
