Description

STAND DER TECHNIKSTATE OF THE ART

Es ist erwünscht, zu Beleuchtungszwecken frei konfigurierbare Beleuchtungsmodule einfach zusammenstecken zu können.It is desirable to be able to simply plug together lighting modules that can be freely configured for lighting purposes.

Die CN 201 652 026 U schlägt hierzu ein rechteckiges, flächiges Lampengehäuse vor, bei dem Leuchtmittel, Leitungen, Schaltungen und Verschraubungen im Inneren des Gehäuses angeordnet sind. Die Gehäuse sind an den Kanten über Schwalbenschwanz-Elemente koppelbar. Hierbei sind die Schwalbenschwanz-Elemente mit Durchbrüchen versehen, durch welche Leitungen auf elektrische Steck-Kontakte durchgeführt sind. Über die Durchbrüche mit durchgeführten Steck-Kontakten sind die Leuchtmittel dann auch elektrisch koppelbar. Die Leuchtfläche ist dadurch anpassbar.The CN 201 652 026 U proposes this a rectangular, flat lamp housing, are arranged in the bulbs, lines, circuits and fittings in the interior of the housing. The housings can be coupled to the edges via dovetail elements. Here, the dovetail elements are provided with openings through which lines are performed on electrical plug-in contacts. About the breakthroughs with plug contacts carried out the bulbs are then also electrically coupled. The illuminated area is thus adaptable.

Die US 7 355 562 B2 schlägt gleichsinnig ein umschließendes, rechteckiges Rahmengehäuse vor, welches ein flächig erstrecktes LED-Array umschließt und über seitliche Schwalbenschwanz-Elemente mit steckbaren Feder-Kontakten sowohl mechanisch als auch elektrisch und elektronisch mit weiteren Elementen verbindbar ist.The US Pat. No. 7,355,562 B2 proposes in the same direction an enclosing, rectangular frame housing, which encloses a flat extended LED array and is connected via lateral dovetail elements with pluggable spring contacts both mechanically and electrically and electronically with other elements.

Die DE 199 14 281 C1 schlägt analog vor, flächenfüllend designte Leuchtmittelgehäuse kantenseitig mit mechanischen Verbindern zu versehen, welche gleichzeitig elektrische Kontakte umfassen.The DE 199 14 281 C1 Proposes analogously to provide surface-comprehensive designed light-emitting housing edge side with mechanical connectors, which simultaneously comprise electrical contacts.

Nach dem Stand der Technik sind somit zumindest Stecker an den Kanten von Gehäusen notwendig, was einerseits die Kosten hochtreibt, andererseits im Resultat keine homogene Oberfläche mehr erzeugen kann.According to the prior art, at least connectors on the edges of housings are thus necessary, which on the one hand drives up the costs, on the other hand, in the result can no longer produce a homogeneous surface.

Aufgabe ist, ohne Stecker und Kabel eine Verbindung zumindest der Versorgungsspannungen zu realisieren.The task is to realize at least one of the supply voltages without connectors and cables.

Die Lösung erfolgt gemäß Patentanspruch 1 durch seitliche Kontaktflächen an Platinen in Kombination mit besonders geformten Nasen und Einbuchtungen. Dadurch können in einer statischen Montage Verbindungen zwischen Platinen ohne Hilfsmittel hergestellt werden, die Kosten sind niedrig und das Erscheinungsbild einwandfrei.The solution is carried out according to claim 1 by lateral contact surfaces on boards in combination with specially shaped noses and indentations. As a result, in a static mounting connections between boards can be made without tools, the cost is low and the appearance impeccable.

Vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Patentansprüchen angegeben.Advantageous embodiments of the invention are specified in the dependent claims.

Erfindungsgemäß werden die Kontaktflächen an besonders geformten Nasen und Einbuchtungen wie bei einem Puzzle-Teil angebracht. Siehe und . Dadurch ist die Verbindung besonders stabil und einfach zu stecken. Insbesondere hält diese Form der Verbindung die Teile auch zusammen und erleichtert zusätzlich die Montage.According to the invention the contact surfaces are attached to specially shaped noses and indentations as in a puzzle part. Please refer and , This makes the connection particularly stable and easy to plug in. In particular, this form of connection holds the parts together and also facilitates assembly.
