Abstract

It is customary for the purpose of optional combination of elongated lamp fixtures (1, 2) to form linear lighting of arbitrary length to provide the end faces of the lamp housing (3) of the elongated lamp fixtures (1, 2) with detachable cover plates (4) which can be anchored one inside another on border strips. In order in this case to realise as simple an assembly as possible, it is proposed to provide the cover plates (4) on the outside with plug-in frames (4d, 4f) which can be joined one inside another on border strips, and to provide as terminal seals for such linear lighting end caps (8) which for the purpose of engaging with the plug-in frames (4d, 4f) of the associated cover plates (4) have a corresponding plug-in frame (4d, 4f) on the inside. <IMAGE>

Description

Technisches GebietTechnical field

Die Erfindung bezieht sich auf eine lichtbandfähige Langfeldleuchte mit einem wannenförmigen über Pendel oder unmittelbar an einer Decke befestigbarem Leuchtengehäuse, das mit lösbaren, die Lampenfassung tragenden stirnseiteigen Abschlußplatten versehen ist.The invention relates to a continuous-row luminaire capable of continuous-row lighting with a trough-shaped luminaire housing which can be fastened via a pendulum or directly to a ceiling and which is provided with detachable end plates which carry the lamp holder.

Zugrundeliegender Stand der TechnikUnderlying state of the art

Lichtbandfähige Langfeldleuchten der erwähnten Art sind beispielsweise durch die Literaturstelle US-PS 3, 599, 911 bekannt. Die Abschlußplatten sind hier Belchstanzteile mit abgewinkelten Rändern, über die sie am Leuchtengehäuse mittels Schrauben oder Nieten befestigt sind. Um eine gegenseitige Verankerung der Abschlußplatten aneinander grenzender Leuchteneinheiten zu ermöglichen weisen die Abschlußplatten auf Umschlag ineinander greifende Haken und Ösen auf. Bei dieser gegenseitigen Art der Verankerung ist es zunächst erforderlich, aneinander grenzende Leuchteneinheiten zunächst bei seitlichem Versatz auf Anschlag zusammenzufügen, und dann die gewünschte Verriegelung zwischen den Abschlußplatten dadurch herbeizuführen, daß der seitliche Versatz rückgängig gemacht wird. Im allgemeinen sind hier nachträgliche Justierarbeiten erforderlich, um ein einwandfreies Fluchten der aneinander grenzenden Leuchteneinheiten im Lichtband sicherzustellen.Continuous-row luminaires of the type mentioned which are capable of continuous-row lighting are known, for example, from the reference US Pat. No. 3,599,911. The end plates are sheet metal stampings with angled edges, over which they are attached to the lamp housing by means of screws or rivets. In order to enable the end plates of mutually adjoining lamp units to be anchored to one another, the end plates have interlocking hooks and eyes on a cover. With this mutual type of anchoring, it is first necessary to first join together adjoining lamp units with a lateral offset to the stop, and then to bring about the desired locking between the end plates by reversing the lateral offset. In general, subsequent adjustment work is required to ensure that the adjoining luminaire units in the continuous row are in perfect alignment.

Offenbarung der ErfindungDisclosure of the invention

Der Erfindung liegt die Aufgabe zugrunde, für eine lichtbandfähige Langfeldleuchte der einleitend genannten Art eine weitere Lösung anzugeben, die die erwähnten Justierarbeiten überflüssig macht und damit die Montagezeit in wünschenswerter Weise abkürzt.The invention has for its object to provide a continuous line luminaire of the type mentioned in the introduction another solution that the adjustment work mentioned makes redundant and thus shorten the assembly time in a desirable manner.

Diese Aufgabe wird gemäß der Erfindung durch die in Schutzanspruch 1 angegebenen Merkmale gelöst.This object is achieved according to the invention by the features specified in claim 1.

Die Ausbildung der Abschlußplatten auf der Außenseite in Form von auf Umschlag ineinander greifenden Steckrahmen ermöglicht es, aneinander zu fügende Leuchteneinheiten in einfacher Weise ineinander zu stecken um die gewünschte Verbindung herzustellen.The design of the end plates on the outside in the form of plug-in frames which interlock with one another makes it possible to simply plug together luminaire units into one another in order to produce the desired connection.

Zweckmäßige Ausgestaltungen der Erfindung sind in den weiteren Schutzansprüchen 2 und 3 angegeben.Appropriate embodiments of the invention are specified in the further claims 2 and 3.

  • Fig. 1 is a schematic representation of a strip of light formed from two linear luminaires in vertical longitudinal section
  • Fig. 2 is a perspective view exploded view of the light assembly according to Figure 1 of the lamp housing with the end plates and the end caps to be locked.

Bester Weg zur Ausführung der ErfindungBest way to carry out the invention

Die schematische Darstellung nach Figur 1 zeigt zwei Langfeldleuchte 1 und 2 mit der Länge L, die gemeinsam zu einem Lichtband der Länge 2L zusammengefügt sind. Jede Langfeldleuchte besteht aus einem Leuchtengehäuse 3 in Form einer u-förmigen Rinne, die jeweils auf beiden Stirnseiten von einer vorzugsweise aus Kunststoff gefertigten Abschlußplatte 4 begrenzt ist. Die Abschlußplatten 4, die identisch gestaltet sind, tragen auf der Innenseite jeweils eine Lampenfassung 5. In zwei einander gegenüberliegenden Lampenfassungen einer Langfeldleuchte 2 ist eine Leuchtstoffröhre 6 eingesetzt. Weiterhin sind die Leuchtengehäuse 3 der Langfeldleuchten 1 und 2 auf seiten ihrer Lichtöffnung mit einem Raster 7 abgedeckt. Die Raster sind an den Anschlußplatten 4 mittels über deren leistenförmige Halterungen 4a übergreifgenden Federbügel 7a lösbar gehaltert. Die unmittelbar aneinander grenzenden Abschlußplatten 4 der Langfeldleuchten 1 und 2 sind steckbar ineinander verankert. Entsprechendes gilt für die Halterung der die äußeren Abdeckplatten 4 des aus den Langfeldleuchten 1 und 2 bestehnden Lichtbandes abdeckenden Endkappen 8.The schematic representation of Figure 1 shows two linear luminaires 1 and 2 with the length L, which are joined together to form a light strip of length 2L. Each linear luminaire consists of a luminaire housing 3 in the form of a U-shaped channel, which is delimited on both end faces by an end plate 4, preferably made of plastic. The End plates 4, which are of identical design, each carry a lamp holder 5 on the inside. A fluorescent tube 6 is inserted in two lamp holders of a linear light 2 lying opposite one another. Furthermore, the luminaire housing 3 of the linear luminaires 1 and 2 are covered with a grid 7 on the side of their light opening. The grids are detachably held on the connection plates 4 by means of spring clips 7a overlapping their strip-shaped holders 4a. The directly adjoining end plates 4 of the linear lights 1 and 2 are anchored in one another. The same applies correspondingly to the mounting of the end caps 8 covering the outer cover plates 4 of the light strip consisting of the linear lights 1 and 2.

Diesen Sachverhalt zu verdeutlichen dient die Figur 2, die die Anordnung nach Figur 1 in ihren Details in p erspektivischer Explosionsdarstellung, und zwar ohne die Leuchtstoffröhren 6 und das Raster 7, zeigt.This situation is illustrated in FIG. 2, which shows the arrangement according to FIG. 1 in its details in a perspective, exploded view, without the fluorescent tubes 6 and the grid 7.

Die Abschlußplatten 4, die alle gleich gestaltet sind, weisen einen äußeren Rahmen 4b auf, der der lichten Weite des Leuchtengehäuses 3 angepaßt und nach unten offen ist. Mit diesem seinem Rahmen 4b ist eine Abschlußplatte 4 jeweils von einer Seite in das Leuchtengehäuse 3 eingeschoben und zwar auf Anschlag an nippelartigen Ansätzen 4c und in dieser Stellung mittels Federrast bzw. einer Schraubklemme, die in Figur 2 nicht dargestellt ist, fixiert.The end plates 4, which are all of the same design, have an outer frame 4b, which is adapted to the clear width of the lamp housing 3 and is open at the bottom. With its frame 4b, an end plate 4 is inserted into the lamp housing 3 from one side, namely against a stop on nipple-like projections 4c and in this position by means of spring catch or a screw terminal, which is not shown in FIG. 2.

Wie Figur 2 ferner zeigt, sind die Abschlußplatten 4 an der Unterseite, die dabei der Lichtöffnungsseeite des Leuchtengehäuses 3 entspricht, gegenüber der Unterseite des Rahmens 4b verkürzt und tragen in ihrem Mittelteil die bereits erwähnten leistenförmigen Halterungen 4a für das Raster 7. Für Kabeldurchführungen können die Anschlußplatten 4, was in Figur 2 nicht dargestellt ist, auch noch zusätzlich Öffnungen aufweisen.As FIG. 2 also shows, the end plates 4 on the underside, which corresponds to the light opening side of the lamp housing 3, are shortened relative to the underside of the frame 4b and carry the strip-shaped brackets 4a for the grid 7 already mentioned in their middle part Connection plates 4, which is not shown in Figure 2, also have additional openings.

Auf ihrer der Lampenfassung 5 gegenüberliegnden Seite, die hierbei jeweils die Außenseite einer Abschlußplatte 4 darstellt, geht der Rahmen 4 in einen Steckrahmen nach Art einer Nut und Feder über, wobei die Nut mit 4d und die Feder mit 4f bezeichnet sind. Die Unterteilung längs der Rahmenstirnseite in eine Nut 4d und eine Feder 4f ist so vorgenommen, daß die Steckrahmen auf Umschlag ineinander steckbar sind. Beim Ausführungsbeispiel nach Figur 2 sind die Steckrahmen so gestaltet, daß der Rahmen 4b auf seiten des Steckrahmens zur Hälfte als Nut 4d und zur Hälfte als Feder 4f ausgeführt ist. Die Unterteilung kann natürlich in beliebiger Weise auch anders erfolgen, beispielsweise in abwechselenden Abschnitten längs des umlaufenden Rahmens in Nut- und Federanschnitte.On its side opposite the lamp holder 5, which in each case represents the outside of an end plate 4, the frame 4 merges into a plug-in frame in the manner of a tongue and groove, the groove being denoted by 4d and the tongue by 4f. The division along the end face of the frame into a groove 4d and a tongue 4f is made in such a way that the plug-in frames can be plugged into one another on the envelope. In the exemplary embodiment according to FIG. 2, the plug-in frames are designed in such a way that the frame 4b on the part of the plug-in frame is designed in half as a groove 4d and in half as a spring 4f. The subdivision can of course also be done in any other way, for example in alternating sections along the circumferential frame into tongue and groove gates.

Die nippelartigen Ansätze 4c die auf seiten des Steckrahmens am äußeren Rand des Rahmens 4 vorgesehen sind, dienen auch beim Zusammenstecken zweier Abschlußplatten 4 gleichzeitig als Anschlag für die nahe Stirnfläche des anschließenden Leuchtengehäuses 3.The nipple-like lugs 4c, which are provided on the side of the plug-in frame on the outer edge of the frame 4, also serve as a stop for the near end face of the subsequent luminaire housing 3 when two end plates 4 are plugged together.

Die Endkappen 8 sind nach Art eines Deckels mit einem umlaufenden Seitenrand 8a gestaltet, dessen freier Rand entsprechend dem Steckrahmen der Abschlußplatten 4 ebenfalls als Steckrahmen mit einer Nut 4d und einer Feder 4f gestaltet ist.The end caps 8 are designed in the manner of a cover with a circumferential side edge 8a, the free edge of which, in accordance with the plug-in frame of the end plates 4, is also designed as a plug-in frame with a groove 4d and a spring 4f.

Wie Figur 2 weiterhin zeigt, ist das Leuchtengehäuse auf seiten seiner Lichtöffnung an beiden Seiten als u-förmige Randschiene 3a gestaltet in die der hier offene Rahmen 4b einer Abschlußplatte 4 jeweils eingreift und sich gegen den Boden dieser u-förmigen Randschiene 3a abstützt.As FIG. 2 also shows, the luminaire housing is designed on both sides of its light opening as a U-shaped edge rail 3a into which the frame 4b of an end plate 4 which is open here engages and is supported against the bottom of this U-shaped edge rail 3a.
