Definitions
- the invention relates to a lamp which has a carrying device in order to keep the lamp housing at the intended height.
- Luminaires are known whose luminaire housings are suspended from a ceiling with pendulum rods or with ropes. Such lights have the disadvantage that the ceiling fixation specifies the suspension location of the lamp housing, and that changes in position of the lamp housing require a new installation. Furthermore, low-voltage lamps are known in which a lamp holder or a lamp housing is suspended on two current-carrying parallel wires, the housing being able to be displaced along the wires. Such safety devices in the form of live wires are not suitable for safety reasons for luminaires that are operated with mains voltage.
- the invention has for its object to provide a lamp, the lamp housing can still be moved with the support device mounted to make changes in position.
- the carrying device has two hollow profile rods through which the supply lines can be passed. Plug-in parts of the lamp housing protrude into the slots of these profile rods. As a result, the lamp housing is engaged at its edges with the profile rods, so that it cannot be moved transversely to the profile rods. However, displacements of the lamp housing in the longitudinal direction of the profile rods are possible.
- the luminaire housing lies with its side edges on the profile rods and is thereby held.
- the profile bars are preferably arranged in a straight line and parallel to each other at a fixed distance. They form rails on which the lamp housing can be attached in any position (in the longitudinal direction), it also being possible for the lamp housing to be displaced while the plug-in parts of the lamp housing are in engagement with the slots.
- the slots are preferably arranged on the upper sides of the profile rods, while the plug-in parts protrude downward from the lamp housing. This makes it possible to place the luminaire housing on the profile rods from above, the plug-in parts engaging with the slots.
- the plug-in parts of the housing preferably engage directly in the slots of the profile rods.
- profile bars e.g. Provide webs or grooves with which the plug-in parts of the lamp housing engage. If the plug-in parts protrude downwards from the luminaire housing and engage in the slots, they prevent the profile rods from spreading apart, so that the luminaire housing contributes to stabilizing the profile rods.
- Cable passage openings can be provided on the side edges of the housing, which openings coincide with the slots in the profile rods.
- the profile bars can be installed in a room in such a way that they form a rail-like network with nodes and branches, and luminaire housings can be attached to each pair of rails.
- the hollow profile rods also serve as cable channels for the supply lines leading to the luminaire housings.
- the lamp according to FIGS. 1 and 2 has an elongated lamp housing 10 which contains fluorescent lamps 11.
- the lamp housing 10 has a convexly curved top wall 12 and a convexly curved bottom wall 13, so that it essentially has the cross section of a biconvex lens.
- a longitudinal light exit opening 14 In the bottom wall 13, above a longitudinal light exit opening 14, there is a luminaire grid 15 made of longitudinal reflectors 16 and transverse reflecting lamellae 17.
- a light exit opening 12a can also be provided in the upper wall 12, through which part of the lamp light is emitted upwards by one to achieve indirect room lighting.
- the upper light exit opening 13 can be closed with an opaque or a translucent cover.
- the walls of the lamp housing 10 consist of profile parts, which are produced, for example, in the extrusion process are and have a constant cross-section over the entire length.
- Auxiliary devices 18, such as ballasts, are accommodated in the side areas of the lamp housing.
- head parts 20 are provided as end walls. These head parts 20 are hollow.
- the connecting device 19 is fastened to a head part 20.
- the support device 21 for the lamp housing 10 consists of two rigid parallel profile bars 22 which are arranged at a mutual distance.
- Each profile rod 22 is designed as a tube which has a longitudinal slot 23 on its upper side.
- the slot edges 24 are bent inwards (FIG. 3).
- the lower wall 13 of the lamp housing 10 each has an inwardly directed formation 26 which is adapted to the outer contour of the profile rod 22 and which closely encloses the profile rod over part of its circumferential region.
- a downwardly directed plug-in part 27 is formed on the lamp housing, which protrudes into the slot 23.
- the plug parts 27 are an integral part of the profile wall of the lamp housing and they extend over the entire length, with the exception of the head parts 20.
- the plug parts 27, which form longitudinal strips, have a closed bottom.
- Fig. 3 shows a cross section through a profile rod 22 in the region of a head piece 20.
- the hollow head part 20 contains a pair of resilient plug-in parts 27a, 27b which engage in the slot 23 and are bulged laterally, so that they engage under the slot edges 24 laterally.
- the lamp housing is latched to the profile rods 22, i.e. it can only be lifted up with a certain amount of force.
- Inside the head parts 20 there are also the cable passage openings 20a between the elastic plug-in parts 27a, 27b.
- the profile rods 22 have a length that is greater than a multiple of the length of the lamp housing.
- the support device 21 is installed in the room and then the luminaire housings are mounted on it at suitable points by simply being placed on the profile rods.
- the lamp can serve as a workplace lamp, for example, with the lamp housing being installed above a workplace.
- the carrying device 21 forms a prefabricated unit in the form of a rigid frame, the profile rods 22 being connected to one another at their end regions by cross members 30. These cross members carry fastening devices 31 for hanging the carrying device 21 from a ceiling.
- the profile rods 22 are longer than the lamp housing 10, so that the lamp housing can be adjusted in the longitudinal direction of the profile rods.

Abstract
Description
Die Erfindung betrifft eine Leuchte, die eine Tragvorrichtung aufweist, um das Leuchtengehäuse in der vorgesehenen Höhe zu halten.The invention relates to a lamp which has a carrying device in order to keep the lamp housing at the intended height.
Bekannt sind Leuchten, deren Leuchtengehäuse mit Pendelstangen oder mit Seilen an einer Decke aufgehängt wird. Solche Leuchten haben den Nachteil, daß die Deckenbefestigung den Aufhängungsort des Leuchtengehäuses vorgibt, und daß Positionsänderungen des Leuchtengehäuses eine Neuinstallation erfordern. Ferner sind Niedervoltleuchten bekannt, bei denen eine Lampenfassung oder ein Leuchtengehause auf zwei stromführenden parallelen Drähten aufgehängt ist, wobei das Gehäuse entlang der Drähte verschoben werden kann. Solche Tragvorrichtungen in Form stromführender Drähte eignen sich aus Sicherheitsgründen aber nicht für Leuchten, die mit Netzspannung betrieben werden.Luminaires are known whose luminaire housings are suspended from a ceiling with pendulum rods or with ropes. Such lights have the disadvantage that the ceiling fixation specifies the suspension location of the lamp housing, and that changes in position of the lamp housing require a new installation. Furthermore, low-voltage lamps are known in which a lamp holder or a lamp housing is suspended on two current-carrying parallel wires, the housing being able to be displaced along the wires. Such safety devices in the form of live wires are not suitable for safety reasons for luminaires that are operated with mains voltage.
Der Erfindung liegt die Aufgabe zugrunde, eine Leuchte zu schaffen, deren Leuchtengehäuse bei montierter Tragvorrichtung noch verschoben werden kann, um Positionsänderungen vorzunehmen.The invention has for its object to provide a lamp, the lamp housing can still be moved with the support device mounted to make changes in position.
Die Lösung dieser Aufgabe erfolgt erfindungsgemäß mit den im Patentanspruch 1 angegebenen Merkmalen.This object is achieved according to the invention with the features specified in claim 1.
Bei der erfindungsgemäßen Leuchte weist die Tragvorrichtung zwei hohle Profilstangen auf, durch die die Versorgungsleitungen hindurchgeführt werden können. In Schlitze dieser Profilstangen ragen Steckteile des Leuchtengehäuses hinein. Dadurch steht das Leuchtengehäuse an seinen Rändern mit den Profilstangen in Eingriff, so daß es nicht quer zu den Profilstangen bewegt werden kann. Jedoch sind Verschiebungen des Leuchtengehäuses in Längsrichtung der Profilstangen möglich. Das Leuchtengehäuse liegt mit seinen Seitenrändern auf den Profilstangen auf und wird dadurch gehalten. Die Profilstangen sind vorzugsweise geradlinig und parallel zueinander mit festem Abstand angeordnet. Sie bilden Schienen, an denen das Leuchtengehäuse in beliebiger Position (in Längsrichtung) angebracht werden kann, wobei vorzugsweise auch eine Verschiebung des Leuchtengehäuses möglich ist, während die Steckteile des Leuchtengehäuses mit den Schlitzen in Eingriff sind.In the luminaire according to the invention, the carrying device has two hollow profile rods through which the supply lines can be passed. Plug-in parts of the lamp housing protrude into the slots of these profile rods. As a result, the lamp housing is engaged at its edges with the profile rods, so that it cannot be moved transversely to the profile rods. However, displacements of the lamp housing in the longitudinal direction of the profile rods are possible. The luminaire housing lies with its side edges on the profile rods and is thereby held. The profile bars are preferably arranged in a straight line and parallel to each other at a fixed distance. They form rails on which the lamp housing can be attached in any position (in the longitudinal direction), it also being possible for the lamp housing to be displaced while the plug-in parts of the lamp housing are in engagement with the slots.
Vorzugsweise sind die Schlitze an den Oberseiten der Profilstangen angeordnet, während die Steckteile von dem Leuchtengehäuse aus nach unten ragen. Dadurch ist es möglich, das Leuchtengehäuse von oben her auf die Profilstangen aufzusetzen, wobei die Steckteile mit den Schlitzen in Eingriff gelangen.The slots are preferably arranged on the upper sides of the profile rods, while the plug-in parts protrude downward from the lamp housing. This makes it possible to place the luminaire housing on the profile rods from above, the plug-in parts engaging with the slots.
Vorzugsweise greifen die Steckteile des Gehäuses unmittelbar in die Schlitze der Profilstangen ein. Es besteht jedoch auch die Möglichkeit, an den Profilstangen zusätzlich zu den Schlitzen andere Profilteile, z.B. Stege oder Nuten, vorzusehen, mit denen die Steckteile des Leuchtengehäuses zusammengreifen. Wenn die Steckteile vom Leuchtengehäuse aus nach unten ragen und in die Schlitze eingreifen, verhindern sie das Auseinanderspreizen der Profilstangen, so daß das Leuchtengehäuse zur Stabilisierung der Profilstangen beiträgt.The plug-in parts of the housing preferably engage directly in the slots of the profile rods. However, there is also the possibility to add other profile parts to the profile bars, e.g. Provide webs or grooves with which the plug-in parts of the lamp housing engage. If the plug-in parts protrude downwards from the luminaire housing and engage in the slots, they prevent the profile rods from spreading apart, so that the luminaire housing contributes to stabilizing the profile rods.
An den Seitenrändern des Gehäuses können Kabeldurchtrittsöffnungen vorgesehen sein, die sich mit den Schlitzen der Profilstangen decken.Cable passage openings can be provided on the side edges of the housing, which openings coincide with the slots in the profile rods.
Die Profilstangen können in einem Raum derart installiert werden, daß sie ein schienenartiges Netzwerk mit Knotenpunkten und Verzweigungen bilden, wobei an jedem Schienenpaar Leuchtengehäuse befestigt werden können. Die hohlen Profilstangen dienen zugleich als Kabelkanäle für die zu den Leuchtengehäusen führenden Versorgungsleitungen.The profile bars can be installed in a room in such a way that they form a rail-like network with nodes and branches, and luminaire housings can be attached to each pair of rails. The hollow profile rods also serve as cable channels for the supply lines leading to the luminaire housings.
Alternativ besteht die Möglichkeit, zwei Profilstangen zur Bildung eines starren Rahmens an ihren Endbereichen durch Traversen miteinander zu verbinden. Auf diese Weise entsteht eine modulartige Tragvorrichtung, die an einer Decke aufgehängt werden kann und in der das Leuchtengehäuse verschiebbar ist.Alternatively, there is the possibility of connecting two profile rods to one another at their end regions to form a rigid frame. In this way, a modular support device is created, which can be hung on a ceiling and in which the lamp housing can be moved.
Im folgenden werden unter Bezugnahme auf die Zeichnungen Ausführungsbeispiele der Erfindung näher erläutert.Exemplary embodiments of the invention are explained in more detail below with reference to the drawings.

Die Leuchte nach den Figuren 1 und 2 weist ein langgestrecktes Leuchtengehäuse 10 auf, das Leuchtstofflampen 11 enthält. Das Leuchtengehäuse 10 hat eine konvex gewölbte Oberwand 12 und eine konvex gewölbte Bodenwand 13, so daß es im wesentlichen den Querschnitt einer bikonvexen Linse hat. In der Bodenwand 13 befindet sich oberhalb einer längslaufenden Lichtaustrittsöffnung 14 ein Leuchtenraster 15 aus längslaufenden Reflektoren 16 und querlaufenden reflektierenden Lamellen 17. In der Oberwand 12 kann ebenfalls eine Lichtaustrittsöffnung 12a vorgesehen sein, durch die hindurch ein Teil des Lampenlichts nach oben abgestrahlt wird, um eine indirekte Raumbeleuchtung zu erzielen. Die obere Lichtaustrittsöffnung 13 kann mit einer lichtundurchlässigen oder einer lichtdurchlässigen Abdeckung verschlossen werden.The lamp according to FIGS. 1 and 2 has an
Die Wände des Leuchtengehäuses 10 bestehen aus Profilteilen, die z.B. im Strangpreßverfahren hergestellt sind und über die gesamte Länge konstanten Querschnitt haben. In den Seitenbereichen des Leuchtengehäuses sind Hilfsgeräte 18, wie z.B. Vorschaltgeräte, untergebracht. Ferner ist dort eine Anschlußvorrichtung 19 untergebracht, mit der externe Versorgungsleitungen an die Leuchten angeschlossen werden können.The walls of the
An den Enden des Leuchtengehäuses 10 sind Kopfteile 20 als Stirnwände vorgesehen. Diese Kopfteile 20 sind hohl. An einem Kopfteil 20 ist die Anschlußvorrichtung 19 befestigt.At the ends of the
Die Tragvorrichtung 21 für das Leuchtengehäuse 10 besteht aus zwei starren parallelen Profilstangen 22, die mit gegenseitigem Abstand angeordnet sind. Jede Profilstange 22 ist als Rohr ausgebildet, das an seiner Oberseite einen längslaufenden Schlitz 23 aufweist. Die Schlitzränder 24 sind nach innen umgebogen (Fig. 3).The
An den parallelen Seitenrändern 25 weist die Unterwand 13 des Leuchtengehäuses 10 jeweils eine nach innen gerichtete Ausformung 26 auf, die der Außenkontur der Profilstange 22 angepaßt ist und die Profilstange über einen Teil ihres Umfangsbereichs eng anliegend umschließt. Im Bereich dieser Ausformung ist an dem Leuchtengehäuse jeweils ein nach unten gerichtetes Steckteil 27 ausgeformt, das passend in den Schlitz 23 hineinragt. Die Steckteile 27 sind einstückiger Bestandteil der Profilwand des Leuchtengehäuses und sie erstrecken sich über die gesamte Länge, mit Ausnahme der Kopfteile 20. Die Steckteile 27, die längslaufende Leisten bilden, haben einen geschlossenen Boden.On the
Fig. 3 zeigt einen Querschnitt durch eine Profilstange 22 im Bereich eines Kopfstücks 20. Das hohle Kopfteil 20 enthält ein Paar federnder Steckteile 27a,27b, die in den Schlitz 23 eingreifen und seitlich ausgebaucht sind, so daß sie die Schlitzränder 24 seitlich untergreifen. Dadurch ist das Leuchtengehäuse rastend an den Profilstangen 22 befestigt, d.h. es kann nur mit einem gewissen Kraftaufwand nach oben abgehoben werden. Im Innern der Kopfteile 20 befinden sich zwischen den elastischen Steckteilen 27a,27b auch die Kabeldurchtrittsöffnungen 20a.Fig. 3 shows a cross section through a
Die Profilstangen 22 haben eine Länge, die größer ist als ein Vielfaches der Länge des Leuchtengehäuses. Die Tragvorrichtung 21 wird in dem Raum installiert und anschließend werden an ihr die Leuchtengehäuse an geeigneten Stellen montiert, indem sie lediglich auf die Profilstangen aufgesetzt werden. Die Leuchte kann beispielsweise als Arbeitsplatzleuchte dienen, wobei das Leuchtengehäuse über einem Arbeitsplatz installiert wird.The
Bei dem Ausführungsbeispiel der Fig. 4 bildet die Tragvorrichtung 21 dagegen eine vorgefertigte Einheit in Form eines starren Rahmens, wobei die Profilstangen 22 an ihren Endbereichen durch Traversen 30 miteinander verbunden sind. Diese Traversen tragen Befestigungsvorrichtungen 31 zum Aufhängen der Tragvorrichtung 21 an einer Decke. Auch hier sind die Profilstangen 22 länger als das Leuchtengehäuse 10, so daß das Leuchtengehäuse in Längsrichtung der Profilstangen justiert werden kann.In the embodiment of FIG. 4, on the other hand, the carrying
