Abstract
Hinterleuchtete Funktionsanordnung, umfassend einen Grundkörper (1) mit einem durchleuchtungsfähigen Bereich (2), eine in einem Abstand hinter diesem Bereich angeordnete Leuchtdiode (LED) als Lichtquelle (3), sowie ein zwischen dem durchleuchtungsfähigen Bereich (2) und der Lichtquelle (3) angeordnetes, opakes Licht lenkendes Element (4), dadurch gekennzeichnet, dass der Grundkörper (1) durch eine Abdeckkappe gebildet ist, die zur Betätigung eines elektrischen Schalters dient und auf ihrer Sichtseite eine die Funktion des Schalters darstellende Funktionssymbolik (2') als durchleuchtungsfähigen Bereich (2) aufweist, dass das opake, Licht lenkende Element (4) als mit Lamellen (5) versehener Reflexionskörper ausgeführt ist und bewirkt, dass zumindest der größte Teil der von der Lichtquelle (3) in Richtung des Grundkörpers (1) abgestrahlten Lichtstrahlen den durchleuchtungsfähigen Bereich (2) nicht direkt erreicht, dass ein Teil der von der Lichtquelle (3) ausgehenden Lichtstrahlen den durchleuchtungsfähigen Bereich (2) nach zumindest einer Reflexion an dem Licht lenkenden Element (4) erreicht, und dass der Reflexionskörper auch die mechanische Übertragung des Drucks auf die Abdeckkappe auf einen jeweils zu betätigenden Schalterbaustein (8, 9) des elektrischen Schalters bewirkt.Backlit functional arrangement, comprising a base body (1) with an area (2) that can be transilluminated, a light-emitting diode (LED) arranged at a distance behind this area as a light source (3), and one between the area (2) and the light source (3) which can be transilluminated. arranged, opaque light-directing element (4), characterized in that the base body (1) is formed by a cover cap which is used to operate an electrical switch and, on its visible side, a functional symbol (2 ') representing the function of the switch as a fluoroscopic area (2) has that the opaque, light-directing element (4) is designed as a reflection body provided with lamellae (5) and has the effect that at least the majority of the light rays emitted by the light source (3) in the direction of the base body (1) transilluminable area (2) does not directly achieve that part of the light rays emanating from the light source (3) the dur chluminous area (2) achieved after at least one reflection on the light-directing element (4), and that the reflection body also effects the mechanical transmission of the pressure on the cover cap to a respective switch module (8, 9) of the electrical switch to be operated.
Description
Die vorliegende Erfindung betrifft eine hinterleuchtete Funktionsanordnung, umfassend einen Grundkörper mit einem durchleuchtungsfähigen Bereich sowie eine in einem Abstand hinter diesem Bereich angeordnete Lichtquelle gemäß dem Oberbegriff des Patentanspruchs 1.The present invention relates to a backlit functional arrangement, comprising a base body with a region capable of transillumination and a light source arranged at a distance behind this region, according to the preamble of patent claim 1.
Eingesetzt werden solche hinterleuchteten Funktionsanordnungen beispielsweise zum Darstellen einer beleuchteten Funktionssymbolik von elektrischen Schaltern, etwa für Kraftfahrzeuge.Such backlit functional arrangements are used, for example, to present an illuminated function symbolism of electrical switches, for example for motor vehicles.
Die
Bedingt durch die Abstrahlcharakteristik der Leuchtdioden, welche im Wesentlichen die einer punktförmigen Lichtquelle ist, wird in der bekannten Anordnung eine Darstellung der eine flächige Ausdehnung aufweisenden Funktionssymbolik mit einer über die Fläche möglichst gleichen Leuchtdichte nicht erreicht. Selbst mit so genannten Argus-Leuchtdioden, bei denen ein Chip mit einer seitlichen Lichtabstrahlung in einem Reflektorgehäuse aufgenommen ist, um eine Abstrahlcharakteristik zu erzielen, die ihre größte Helligkeit nicht im Zentrum der Abstrahlkeule hat, wird eine zufrieden stellende Gleichmäßigkeit insbesondere bei großflächigeren Symbolen nicht erreicht.Due to the emission characteristics of the light-emitting diodes, which is essentially that of a punctiform light source, in the known arrangement a representation of the function symbols having a planar extension is not achieved with a luminance that is as uniform as possible over the surface. Even with so-called Argus LEDs, in which a chip with a lateral light emission is accommodated in a reflector housing in order to achieve a radiation characteristic which does not have its greatest brightness in the center of the radiation lobe, a satisfactory uniformity is not achieved, especially with larger area symbols ,
Die
Die hinterleuchtete Funktionsanordnung nach der vorliegenden Erfindung bildet die eingangs genannte gattungsgemäße hinterleuchtete Funktionsanordnung dergestalt weiter, dass die zu dem diskutierten Stand der Technik aufgezeigten Nachteile vermieden sind.The backlit functional arrangement according to the present invention further forms the above-mentioned generic backlit functional arrangement in such a way that the disadvantages pointed out to the discussed prior art are avoided.
Dies ist ermöglicht durch die kennzeichnenden Merkmale des Patentanspruchs 1.This is made possible by the characterizing features of claim 1.
Die Zeichnung zeigt eine Schnittdarstellung einer erfindungsgemäßen hinterleuchteten Funktionsanordnung in einem elektrischen Schalter sowie eine Ansicht des mit Lamellen versehenen Reflexionskörpers, der in dieser Konfiguration als lichtlenkendes Element dient.The drawing shows a sectional view of a backlit functional arrangement according to the invention in an electrical switch and a view of the finned reflection body, which serves as a light-directing element in this configuration.
Die gezeigte hinterleuchtete Funktionsanordnung gehört zu einem elektrischen Schalter für ein Kraftfahrzeug, bei dem in einem Gehäuse
