The light guide layer has an optically transparent material different from glass, and the light-emitting semiconductor component is arranged on an edge (6) of the light guide layer.
Description
Die Erfindung betrifft eine Anordnung eines lichtemittierenden Halbleiterbauelementes, insbesondere einer LED, und einer Lichtleiterschicht, die insbesondere in der Automobiltechnik als Brems- oder Schlussleuchte oder als Spiegel mit integrierter Blinkerfunktion verwendet werden kann.The invention relates to an arrangement of a light-emitting semiconductor component, in particular an LED, and a light guide layer, which can be used in particular in automotive technology as a brake or tail light or mirror with integrated turn signal function.

Aufgabe der Erfindung ist es, eine einfach herstellbare und universell, insbesondere im Automobilbau, einsetzbare Leuchte anzugeben, die in einem ausgeschalteten Betriebszustand transparent ist oder als Spiegel fungiert.The object of the invention is to provide an easily manufacturable and universally applicable, in particular in the automotive industry, usable light that is transparent in an off mode or acts as a mirror.
Diese Aufgabe wird durch eine Anordnung eines lichtemittierenden Halbleiterbauelementes und einer Lichtleiterschicht mit den Merkmalen des Anspruches 1 gelöst. Ausgestaltungen und zweckmäßige Verwendungen ergeben sich aus den abhängigen Ansprüchen.This object is achieved by an arrangement of a light-emitting semiconductor component and a light-conducting layer having the features of
Bei der Anordnung sind das lichtemittierende Halbleiterbauelement und die Lichtleiterschicht derart benachbart zueinander angeordnet, dass von dem Halbleiterbauelement emittiertes Licht in die Lichtleiterschicht eingekoppelt wird. Die Lichtleiterschicht weist ein von Glas verschiedenes optisch transparentes Material auf, und das lichtemittierende Halbleiterbauelement ist an einer Kante der Lichtleiterschicht angeordnet. Eine Kante ist eine seitliche Berandung der flächigen Ausdehnung der Lichtleiterschicht. Die flächige Ausdehnung der Lichtleiterschicht ist vorzugsweise nicht für eine Lichtleitung in einer bevorzugten Richtung, sondern für eine flächige Verteilung des Lichtes vorgesehen, damit die Anordnung die Funktion einer Leuchte erfüllt.In the arrangement, the light-emitting semiconductor component and the optical waveguide layer are arranged adjacent to one another such that light emitted by the semiconductor component is coupled into the optical waveguide layer. The light guide layer has an optically transparent material other than glass, and the light emitting semiconductor device is disposed at an edge of the light guide layer. An edge is a lateral boundary of the planar extension of the light guide layer. The planar extension of the light guide layer is preferably not intended for a light pipe in a preferred direction, but for a flat distribution of the light, so that the arrangement fulfills the function of a lamp.
Bei einem Ausführungsbeispiel umfasst die Anordnung zusätzlich eine Basisschicht, die ein von der Lichtleiterschicht verschiedenes optisch transparentes Material aufweist. Die Lichtleiterschicht ist auf oder über der Basisschicht angeordnet.In one embodiment, the arrangement additionally comprises a base layer which has an optically transparent material other than the optical waveguide layer. The light guide layer is arranged on or above the base layer.
Bei einem weiteren Ausführungsbeispiel umfasst die Anordnung zusätzlich eine Basisschicht, die ein optisch opakes Material aufweist. Die Lichtleiterschicht ist auf oder über der Basisschicht angeordnet.In a further embodiment, the arrangement additionally comprises a base layer comprising an optically opaque material. The light guide layer is arranged on or above the base layer.
Bei einem weiteren Ausführungsbeispiel ist die Basisschicht eine Heckscheibe eines FahrzeugsIn a further embodiment, the base layer is a rear window of a vehicle
Bei einem weiteren Ausführungsbeispiel ist die Basisschicht eine Karosserie eines Fahrzeugs.In a further embodiment, the base layer is a body of a vehicle.
Bei einem weiteren Ausführungsbeispiel umfasst die Anordnung zusätzlich eine Reflektorschicht. Die Lichtleiterschicht ist auf oder über der Reflektorschicht angeordnet.In a further embodiment, the arrangement additionally comprises a reflector layer. The light guide layer is arranged on or above the reflector layer.
Bei einem weiteren Ausführungsbeispiel ist eine optisch transparente Basisschicht aus einem von der Lichtleiterschicht verschiedenen Material zwischen der Lichtleiterschicht und der Reflektorschicht angeordnet.In another embodiment, an optically transparent base layer made of a different material from the light guide layer material between the light guide layer and the reflector layer is arranged.
Bei einem weiteren Ausführungsbeispiel ist eine optisch transparente Basisschicht aus einem von der Lichtleiterschicht verschiedenen Material auf der von der Reflektorschicht abgewandten Seite der Lichtleiterschicht angeordnet.In a further embodiment, an optically transparent base layer made of a different material from the light guide layer material is arranged on the side facing away from the reflector layer side of the light guide layer.
Bei einem weiteren Ausführungsbeispiel ist die Lichtleiterschicht nur auf oder über einem Anteil der Reflektorschicht, nicht auf oder über der gesamten Reflektorschicht angeordnet.In a further embodiment, the light guide layer is arranged only on or over a portion of the reflector layer, not on or over the entire reflector layer.
Bei einem weiteren Ausführungsbeispiel umfasst die Anordnung zusätzlich ein Gehäuse, das die Anordnung teilweise umgibt. Dieses Ausführungsbeispiel kann insbesondere in einem ersten Betriebszustand als Rückspiegel eines Fahrzeugs und in einem zweiten Betriebszustand als Fahrtrichtungsanzeiger oder als Fahrtrichtungsanzeiger und Rückspiegel eines Fahrzeugs vorgesehen sein.In a further embodiment, the arrangement additionally comprises a housing which partially surrounds the arrangement. This embodiment may be provided in particular in a first operating state as a rearview mirror of a vehicle and in a second operating state as a direction indicator or as a direction indicator and rearview mirror of a vehicle.
