Mehrfach-LeuchtdiodenanordnunqMultiple light emitting diode arrangement

In der heutigen Technik finden Leuchtdioden immer mehr Anwendung. So geht man beispielsweise dazu über, in bestimmten Fällen Leuchten mit Glühbirnen oder Leuchtstofflampen durch flächenhafte Leuchtdiodendisplays zu ersetzen. Dies gilt beispielsweise auch für Begrenzungs-, Rückleuchten und Blinkleuchten von Kraftfahrzeugen. Der Ersatz der üblichen Rückleuchten und Blinkleuchten durch Mehrfach-Leuchtdiodenanordnungen ist im wesentlichen darauf zurückzuführen, daß Rückleuchten bzw. Blinkleuchten mit den üblichen Glühbirnen bzw. Leuchtstofflampen einen relativ großen Raumbedarf (tiefe Bauweise) haben, während Leuchten aus Leuchtdioden relativ flach ausgebildet und leicht der jeweiligen Unterlage wie z. B. einem Kotflügel angepaßt werden können. Kleine Bautiefe auch bei großer Abstrahlfläche und gute Anpassung an die jeweilige Karosserie ist aber eine wesentliche Voraussetzung für einen geringen Luftwiderstand eines Fahrzeuges.In today's technology, light-emitting diodes are used more and more. For example, in certain cases, lights with incandescent or fluorescent lamps are used to replace extensive light-emitting diode displays. This is the case, for example also for marker lights, taillights and indicators of motor vehicles. The replacement of the usual taillights and flashing lights through multiple light emitting diodes is essentially due to the fact that taillights or flashing lights with the usual light bulbs or fluorescent lamps take up a relatively large amount of space (deep construction), while lights made of light-emitting diodes have a relatively flat design and light the respective base such as B. can be adapted to a fender. Small overall depth even with a large radiation surface and good Adaptation to the respective body is an essential prerequisite for a low air resistance Vehicle.

Der Erfindung liegt die Aufgabe zugrunde, eine Mehrfach-Leuchtdiodenanordnung anzugeben, die großflächig und gleichzeitig flach ausgebildet werden kann, die der jeweiligen Unterlage leicht angepaßt werden kann und die außerdem leicht und kostengünstig herstellbar ist. Diese Aufgabe wird nach der Erfindung durch eine Mehrfach-Leuchtdiodenanordnung gelöst, bei der der Leuchtdiodenträger eine Mehrzahl von Reflektoren aufweist, in denen die Leuchtdioden angeordnet sind, und bei der die Reflektoren streifenförmig oder matrixartig zusammengefaßt sind. Die Erfindung ist nicht auf Dioden beschränkt, sondern anstelle von Dioden können ebenso ande're Leuchtelemente auf Halbleiterbasis Anwendung finden.The invention is based on the object of a multiple light-emitting diode arrangement indicate that can be formed over a large area and at the same time flat, that of the respective base can be easily adapted and which is also easy and inexpensive can be produced. This object is achieved according to the invention by a multiple light emitting diode arrangement in which the Light-emitting diode carrier has a plurality of reflectors in which the light-emitting diodes are arranged, and in which the reflectors are summarized in strips or in a matrix. The invention is not restricted to diodes, but instead of diodes it is also possible to use other light-emitting elements based on semiconductors Find application.

Die Reflektoren eines Streifens oder einer Matrix sind miteinander verbunden, und zwar beispielsweise durch Verbindungsstege. Um zu einer großflächigen Mehrrach-Leuchtdiodenanordnung zu kommen, wird vorzugsweise eine Mehrzahl von Reflektorstreifen nebeneinander angeordnet. Durch eine entsprechende Nebeneinanderanordnung von Reflektorstreifen läßt sich eine beliebig große Mehrfach-Leuchtdiodenanordnung erzielen» The reflectors of a strip or a matrix are with each other connected, for example by connecting webs. In order to create a large-area multiple light-emitting diode arrangement To come, a plurality of reflector strips is preferably arranged next to one another. With a corresponding Side by side arrangement of reflector strips can a multiple light emitting diode arrangement of any size can be achieved »

Die Kontaktierung der Leuchtdioden der Mehrfach-Leuchtdiodenanordnung erfolgt beispielsweise durch Kontaktstreifen, die zwischen je zwei Reflektorstreifen angeordnet werden. Zur Kontaktierung der Leuchtdioden werden Zuleitungen von den Leuchtdioden zu den Kontaktstreifen geführt.The contacting of the light emitting diodes of the multiple light emitting diode arrangement takes place, for example, by contact strips that are arranged between each two reflector strips. To the Contacting the light-emitting diodes, leads are routed from the light-emitting diodes to the contact strips.

Die Reflektorstreifen oder Reflektormatrizen werden beispielsweise aus einem gemeinsamen Materialstück wie z.B. Aluminium hergestellt. Die Reflektorstreifen oder Reflektormatrizen werden vorzugsweise auf einer Unterlage angeordnet, die beispielsweise aus einem Künststoff besteht. Sowohl die Unterlage für die Reflektorstreifen als auch die Reflektorstreifen bzw. Reflektormatrizen selbst sollen möglichst flexibel ausgebildet sein, damit die Mehrfach-Leuchtdiodenanordnung nach der Erfindung in einfacher Weise auch gewölbten Gegenständen wie z. B. den Kotflügeln eines Kraftfahrzeuges angepaßt werden kann.The reflector strips or reflector matrices are for example made from a common piece of material such as aluminum. The reflector strips or reflector matrices are preferably arranged on a base made, for example, of a synthetic material. Both the pad for the reflector strips as well as the reflector strips or reflector matrices themselves should be designed to be as flexible as possible be so that the multiple light emitting diode arrangement according to the invention in a simple manner also curved objects such as B. adapted to the fenders of a motor vehicle can be.

Auf die Reflektoren und damit- auch auf die in den Reflektoren befindlichen Leuchtdioden wird vorzugsweise eine Abdeckung aufgebracht, die zur Erhöhung der Leuchtkraft der Leuchtdioden vorzugsweise linsenförmig ausgebildet ist. Die Abdeckung, die natürlich lichtdurchlässig sein muß, besteht beispielsweise aus Epoxy.A cover is preferably placed on the reflectors and thus also on the light-emitting diodes located in the reflectors applied, which is preferably designed lens-shaped to increase the luminosity of the light-emitting diodes. The cover that must of course be translucent, consists for example of epoxy.

Die Erfindung wird im folgenden an Ausführungsbeispielen erläutert. The invention is explained below using exemplary embodiments.

Die Figur la zeigt einen Reflektorstreifen nach der Erfindung, der auch als Reflektorzeile bezeichnet werden kann. Ein Reflektorstreifen, der als Träger für die Leuchtdioden dient, besteht gemäß der Figur 1 aus mehreren miteinander verbundenen Reflektoren 1, die gemäß der Figur Ib zur Aufnahme der Leuchtdioden 2 dienen. Zur Erzielung einer großflächigen Leuchtfläche bzw. zur Erzielung einer bestimmten Leuchtkraft werden die Reflektorstreifen gemäß den Figuren 3 und 5 vorzugsweise matrixartig nebeneinander angeordnet. Der Reflektorstreifen der Figur 1 weist aus Darstellungsgründen nur vier Reflektoren 1 auf, während in der Praxis im allgemeinen wesentlich mehr Reflektoren bei einem Reflektorstreifen vorhanden sind. Die Leuchtdioden 2 werden gemäß der Figur Ib am Boden der Reflektoren 1 angeordnet. Die Reflektoren 1, die im allgemeinen wannenförmig ausgebildet sind, sind gemäß der Figur 1 durch Stege 3 miteinander verbunden. Die Reflektorstreifen werden vorzugsweise aus einem Materialstück, beispielsweise durch Stanzen und Verformen, hergestellt. Als Material für die Reflektoren und damit auch für die Reflektorstreifen eignet sich beispielsweise Aluminium.The figure la shows a reflector strip according to the invention, which can also be referred to as a reflector line. A reflective strip, which serves as a carrier for the light-emitting diodes consists of several interconnected according to FIG. 1 Reflectors 1 according to FIG. Ib for receiving the light-emitting diodes 2 serve. The reflector strips are used to achieve a large-area luminous area or to achieve a certain luminosity according to FIGS. 3 and 5, preferably arranged next to one another in the manner of a matrix. The reflective strip of the For reasons of illustration, FIG. 1 has only four reflectors 1, while in practice there are generally many more reflectors are present in the case of a reflective strip. The light-emitting diodes 2 are shown in FIG. 1b on the bottom of the reflectors 1 arranged. The reflectors 1, which are generally trough-shaped, are through according to FIG Web 3 interconnected. The reflective strips will be preferably made from a piece of material, for example by punching and deforming. As material for the reflectors and therefore also suitable for the reflective strips for example aluminum.

Bei der Anordnung der Figur 2 sind die Reflektoren 1 matrixartig angeordnet. Es empfiehlt sich jedoch, gemäß der Figur 3 von Reflektorstreifen auszugehen und mehrere Reflektorstreifen nebeneinander anzuordnen, wodurch gemäß den Figuren 3 und. 5 ebenfalls eine matrixartige Anordnung erzielt wird. Diese matrixartige Anordnung dient als Träger für die Leuchtdioden, die in den Reflektoren der Matrix angeordnet werqen.In the arrangement of FIG. 2, the reflectors 1 are arranged like a matrix. It is recommended, however, according to FIG starting from reflector strips and to arrange several reflector strips side by side, whereby according to Figures 3 and. 5 a matrix-like arrangement is also achieved. This matrix-like arrangement serves as a carrier for the light-emitting diodes, which werqen arranged in the reflectors of the matrix.

Es empfiehlt sich, relativ lange Reflektorstreifen herzustellen und diese dann auf die erforderliche Länge zuzuschneiden. Zur Kontaktierung der Leuchtdioden 3 sind bei den Anordnungen der Figuren 3 und 5 zwischen den Reflektorstreifen Kontaktstreifen 4 angeordnet. Beim Ausführungsbeispiel der Figuren 3 und 5 weisen die Kontaktstreifen 4 Erweiterungsflächen 5 als Kontaktflächen auf. Die Kontaktierung der Leuchtdioden 1 erfolgt durch Zuleitungsdrähte 6, die zwischen den Elektroden der Leuchtdioden 2 und den Kontaktflächen 5 verlaufen. Die Zuleitungsdrähte 6 werden beispielsweise durch Bonden befestigt. It is advisable to make relatively long reflective strips and then cut them to the required length. To contact the light emitting diodes 3 are in the arrangements of FIGS. 3 and 5 are arranged between the reflector strips and contact strips 4. In the embodiment of FIGS. 3 and 5 the contact strips 4 have expansion areas 5 as contact areas on. The light-emitting diodes 1 are contacted by lead wires 6 that are inserted between the electrodes of the light-emitting diodes 2 and the contact surfaces 5 run. The lead wires 6 are attached, for example, by bonding.

Wie die Figur 4 zeigt, werden die Reflektorstreifen sowie auch die Kontaktstreifen 4 vorzugsweise auf eine Unterlage 7 aufgebracht. Die Unterlage 7 sollte möglichst fexibel ausgebildet sein, damit die Mehrfach-Leuchtdiodenanordnung auch gewölbten Gegenständen wie z. B. Kotflügeln angepaßt werden kann. Sind mehrere Reflektorstreifen matrixartig zusammengefaßt, wie dies beispielsweise bei der Figur 5 der Fall ist, so erhalten die Reflektorstreifen gemäß der Figur 5 vorzugsweise eine gemeinsame Unterlage oder Trägerkörper 7, der ebenfalls eine bestimmte Flexibilität aufweisen sollte. Die Unterlage 7 besteht sowohl bei den einzelnen Reflektorstreifen als auch bei der matrixartigen Anordnung vorzugsweise aus einem Kunststoff.As Figure 4 shows, the reflector strips are as well the contact strips 4 are preferably applied to a base 7. The base 7 should be designed to be as flexible as possible be so that the multiple light emitting diode array is also curved Objects such as B. fenders can be adjusted. Are several reflector strips combined like a matrix, like this is the case, for example, in FIG. 5, the reflector strips according to FIG. 5 preferably have a common one Base or support body 7, which should also have a certain flexibility. Document 7 consists both in the case of the individual reflector strips and in the case of the matrix-like arrangement, preferably made of a plastic.

Wie die Figur 4 zeigt, werden die Leuchtdioden auf der Oberseite der Anordnung vorzugsweise abgedeckt. Die Abdeckung 8, die im Bereich der Leuchtdioden bzw. der Reflektoren zur Erhöhung der Leuchtstärke vorzugsweise linsenförmig ausgebildet ist, ist lichtdurchlässig.As Figure 4 shows, the light emitting diodes are on the top the arrangement preferably covered. The cover 8, which is in the area of the light emitting diodes or the reflectors to increase the luminosity is preferably lens-shaped, is translucent.
