Abstract
Description
Die vorliegende Erfindung bezieht sich auf eine Beleuchtungsvorrichtung gemäß dem Patentanspruch 1.The The present invention relates to a lighting device according to the claim 1.
Es ist allgemein bekannt, ein auf einer Frontseite eines Trägers befindliches Leuchtmittel mittels UV-Licht zum Leuchten zu bringen, indem das Leuchtmittel von der Frontseite her mittels einer UV-Lichtquelle bestrahlt wird.It is well known, a located on a front side of a wearer Illuminate means of ultraviolet light to light up by the bulbs is irradiated from the front by means of a UV light source.
Der Erfindung liegt die Aufgabe zugrunde, eine kompakte, sicher funktionierende und optisch ansprechende Beleuchtungsvorrichtung zu schaffen.Of the Invention is based on the object, a compact, safe working and to provide visually appealing lighting device.
Diese Aufgabe wird durch die im Patentanspruch 1 angegebenen Merkmale gelöst.These The object is achieved by the features specified in claim 1 solved.
Eine erfindungsgemäße Beleuchtungsvorrichtung umfaßt einen lichtleitfähigen Träger, der eine Fluoreszenzschicht aufweist. Eine UV-Lichtquelle ist so mit dem lichtleitfähigen Träger gekoppelt, daß der lichtleitfähige Träger eine Lichttransmission von der UV-Lichtquelle zur Fluoreszenzschicht ausführt. Dadurch wird der inhomogene Lichtkegel der UV-Lichtquelle in ein homogenes, gleichmäßig leuchtendes blendfreies Licht umgewandelt. Die erfindungsgemäße Beleuchtungsvorrichtung ist kompakt ausgebildet und hat ein angenehmes äußeres Erscheinungsbild. Da auch nach dem Ausschalten der UV-Lichtquelle ein Nachleuchten durch die Fluoreszenzschicht bewirkt wird, kann die Beleuchtungsvorrichtung mit geringem Energieaufwand betrieben werden.A Lighting device according to the invention comprises a photoconductive Carrier, having a fluorescent layer. A UV light source is like that with the photoconductive carrier coupled, that the photoconductive support a Light transmission from the UV light source to the fluorescent layer performs. As a result, the inhomogeneous light cone of the UV light source in a homogeneous, evenly glare-free Converted light. The lighting device according to the invention is compact and has a pleasant appearance. There even after turning off the UV light source by a afterglow the fluorescent layer is effected, the lighting device be operated with low energy consumption.
