Abstract

The lamp has a fixation area provided for fixing of a hanging element i.e. wire rope (2). The fixation area has a guidance slot aligned transverse to a longitudinal extension of the lamp, where an end area of the hanging element facing the lamp is guided into the guidance slot. The guidance slot is partially covered by a plate shaped element i.e. segment plate (5), with a slot designed radial to a rotary point, where the slot is movable over the guidance slot. The slot receives an end area of the hanging element and is movable into the guidance slot during rotation of the plate shaped element.

Description

Die Erfindung betrifft eine langgestreckte Hängeleuchtemit mindestens einem Befestigungsbereich zur Halterung eines Endbereichs eines Aufhängeelements, insbesondere eines Seils, an einem Seilhalterungspunkt, wobei dieser seitlich zur Längserstreckung der Leuchte verschoben werden kann.The invention relates to an elongate hanging lamp with at least one mounting portion for holding an end portion of a suspension element, in particular a rope, at a cable support point, wherein this can be moved laterally to the longitudinal extension of the lamp.

Leuchten werden häufig über Seile oder andere flexible Aufhängeelemente an einem Träger, beispielsweise einer Decke eines Raums aufgehängt. Die Seile greifen in Befestigungsbereichen an der Leuchte, beispielsweise am Leuchtengehäuse oder an einem Verbindungselement zwischen mehreren Leuchtengehäusen an. Dies geschieht in einem im Befestigungsbereich vorhandenen Seilhalterungspunkt, d. h. in einem näherungsweise punktförmigen Bereich, an dem die Lastabtragung der Leuchte auf das Seil erfolgt.Lights are often hung on ropes or other flexible suspension on a support, such as a ceiling of a room. The ropes engage in mounting areas on the lamp, for example on the lamp housing or on a connecting element between a plurality of lamp housings. This is done in a present in the attachment area cable support point, d. H. in an approximately punctiform area where the load is transferred to the rope.

Bei derartigen Leuchten kann sich das Problem stellen, dass unterschiedliche Gewichtsverteilung bezüglich eines Symmetriezentrums oder einer Symmetrieebene der Leuchte eine unerwünschte Schrägstellung der hängenden Leuchte bewirken. Eine solche unsymmetrische Gewichtsverteilung kann sich beispielsweise durch Toleranzen der Materialstärken der einzelnen Bauteile, durch asymmetrische Einbauteile und/oder durch Montagetoleranzen ergeben. Insbesondere mehrflügelige Leuchten, bei denen Leuchtmittel zu beiden Seiten eines an Seilen hängenden Verbindungselements angeordnet sind, können durch ihre vergleichsweise große Breite diesen Effekt ausgeprägt zeigen. Der Fehler kann korrigiert werden, wenn der Seilhalterungspunkt so verschoben werden kann, dass er in der gewünschten Einbaulage der Leuchte senkrecht über dem Schwerezentrum liegt.In such lights, the problem may arise that different weight distribution with respect to a center of symmetry or a plane of symmetry of the lamp cause an undesirable inclination of the hanging lamp. Such asymmetrical weight distribution can result, for example, from tolerances of the material thicknesses of the individual components, from asymmetrical built-in components and / or from assembly tolerances. In particular, multi-leaf lights in which Illuminants are arranged on both sides of a hanging on ropes connecting element, can show this effect pronounced by their comparatively large width. The error can be corrected if the cable support point can be moved so that it lies in the desired mounting position of the lamp vertically above the center of gravity.

Bei einer bekannten Hängeleuchte ( EP 1479969 A2 ) wird dies erreicht, indem der Seilhalterungspunkt exzentrisch in einem im Befestigungsbereich drehbaren Seilaufhänger angebracht ist. Beim Drehen des Aufhängers bewegt sich der Seilhalterungspunkt auf einem Kreisbogen mit Komponenten parallel und quer zur Längserstreckung der Leuchte. Eine weitere langgestreckte Leuchte ist aus der US 61 32 061 A bekannt.In a known suspension lamp ( EP 1479969 A2 ) this is achieved by the cable support point is mounted eccentrically in a rotatable in the mounting area cable hanger. When turning the hanger, the cable support point moves on a circular arc with components parallel and transverse to the longitudinal extent of the luminaire. Another elongated light is from the US 61 32 061 A known.

Diese Anordnung wirkt befriedigend, wenn die Leuchte an mindestens zwei in Längsrichtung der Leuchte beabstandeten Seilen hängt, weil dann die Verschiebung des Seilhalterungspunktes in dieser Richtung kein Kippen der Leuchte bewirken kann. Allerdings kann durch die Verschiebung des Seilhalterungspunktes in Längsrichtung der Leuchte ein ästhetisch unbefriedigender Eindruck entstehen, weil die Seile dann mehr oder weniger von der Senkrechten relativ zur Leuchte abweichen.This arrangement is satisfactory when the lamp depends on at least two spaced in the longitudinal direction of the lamp ropes, because then the displacement of the cable support point in this direction can not cause tilting of the lamp. However, the displacement of the cable support point in the longitudinal direction of the lamp may result in an aesthetically unsatisfactory impression because the cables then deviate more or less from the vertical relative to the luminaire.

Aus DE 4010416 A1 ist eine Aufhängevorrichtung für Leuchten bekannt bei der ein am Leuchtengehäuse montierbares Halteteil mit einer waagerecht verlaufenden Führung versehen ist und eine entlang der Führung verschiebbare Klemmvorrichtung das Ende des Seils aufnehmen kann. Abhängig von der Einbaurichtung des Halteteils kann damit sowohl einer an einem Seil hängende langgestreckte Leuchte in Längsrichtung als auch eine an zwei Seilen hängende Leuchte in Querrichtung in die Waagerechte justiert werden. Diese Vorrichtung ist jedoch im Aufbau kompliziert und in der Handhabung unbequem, unter anderem, weil sie mit zwei Händen bedient werden muss.Out DE 4010416 A1 a suspension device for lighting is known in which a mountable on the lamp housing holding part is provided with a horizontally extending guide and a sliding along the guide clamping device can accommodate the end of the rope. Depending on the installation direction of the holding part so that both a hanging on a rope elongated light in the longitudinal direction and a suspended on two ropes lamp can be adjusted in the transverse direction in the horizontal. However, this device is complicated in construction and inconvenient to use, among other things because it has to be operated with two hands.

Die vorliegende Erfindung stellt sich daher die Aufgabe, eine Hängeleuchte anzugeben, welche die beschriebenen Nachteile des Standes der Technik vermeidet.The present invention therefore has as its object to provide a suspended luminaire, which avoids the disadvantages of the prior art described.

Diese Aufgabe wird gelöst durch eine Hängeleuchte nach dem Hauptanspruch.This object is achieved by a pendant lamp according to the main claim.

Der Aufbau einer solchen Hängeleuchte wird gegenüber dem Stand der Technik dadurch wesentlich vereinfacht, dass der Befestigungsbereich an der Leuchte selbst vorgesehen ist und kein separat zu montierendes Teil notwendig ist. Auch die Bedienung ist einfacher, weil eine Drehbewegung leichter und genauer ausführbar ist als eine Verschiebung und überdies auch mit einer Hand ausgeführt werden kann. Durch geeignete Bemessung des scheibenförmigen Elements mit dem darin ausgebildeten Schlitz kann das "Llbersetzungsverhältnis", das heißt, die Verschiebung des Seilhalterungspunktes bei einer bestimmten Winkelbewegung des scheibenförmigen Elements, leicht den Anforderungen angepasst werden.The construction of such a suspension lamp is compared to the prior art thereby significantly simplified that the mounting area is provided on the lamp itself and no separately to be mounted part is necessary. Also, the operation is easier because a rotational movement is easier and more accurate executable than a shift and also can be performed with one hand. By suitably dimensioning the disk-shaped element with the slot formed therein, the "transmission ratio", that is, the displacement of the cable support point at a certain angular movement of the disk-shaped element, can be easily adapted to the requirements.

Als Aufhängeelement kommt insbesondere ein Seil aus Metalldraht oder pflanzlicher oder synthetischer Faser wie Hanf oder Polyamid zur Anwendung. Es sind aber auch Drähte oder Monofile oder auch Bänder, gegebenenfalls geflochten, verwendbar, wenn ihre Endbereiche so gestaltet werden dass sie vom Befestigungsbereich aufgenommen werden können.As a suspension especially a rope of metal wire or vegetable or synthetic fiber such as hemp or polyamide is used. But there are also wires or monofilaments or tapes, optionally braided, usable if their end portions are designed so that they can be absorbed by the mounting area.

Vorteilhaft ist der mindestens eine Befestigungsbereich mit Führungsschlitz und scheibenförmigem Element am Leuchtengehäuse selbst ausgebildet. Dies ist insbesondere dann möglich, wenn die Leuchte relativ schmal und lang gestreckt gestaltet ist.Advantageously, the at least one mounting area with guide slot and disk-shaped element is formed on the lamp housing itself. This is especially possible if the lamp is designed relatively narrow and long stretched.

In der Regel ist der mindestens eine Befestigungsbereich angenähert in der Mitte relativ zur Querrichtung der Leuchte angebracht. Wenn die Leuchte zwei oder eine andere gerade Zahl von zueinander parallelen Leuchtengehäusen aufweist, die an mindestens einem Verbindungselement symmetrisch angeordnet sind, ist der Befestigungsbereich vorteilhaft am Verbindungselement ausgebildet.As a rule, the at least one fastening region is mounted approximately in the middle relative to the transverse direction of the luminaire. If the lamp has two or another even number of mutually parallel light housings, the at least a connection element are arranged symmetrically, the attachment area is advantageously formed on the connecting element.

Mit dem erfindungsgemäß gestalteten Befestigungsbereich kann eine an nur einem Seil hängende Leuchte in Längs- oder Querrichtung waagerecht ausgerichtet werden. Bevorzugt sind jedoch mindestens zwei Befestigungsbereiche vorhanden, die in der Längserstreckung der Leuchte beabstandet sind. Beispielsweise können sie in der Nähe der Enden der Leuchte liegen.With the inventively designed attachment area a hanging on only one rope light in the longitudinal or transverse direction can be aligned horizontally. However, at least two attachment regions are preferably present, which are spaced apart in the longitudinal extent of the luminaire. For example, they may be near the ends of the luminaire.

Das scheibenförmige Element kann beispielsweise eine Kreisscheibe sein. Da jedoch in der Regel nur ein Führungsschlitz vorhanden ist, kann das scheibenförmige Element zur Materialersparnis auf den näherungsweise zwischen Drehpunkt und Führungsschlitz befindlichen Bereich beschränkt und bevorzugt angenähert als Kreissegmentscheibe ausgebildet sein. Eine solche Segmentscheibe braucht nur in der Nähe des Drehpunkts eine für die Festigkeit der Verbindung mit dem Befestigungsbereich ausreichende Materialmenge und im Segment soviel Material wie für die Überdeckung des Führungsschlitzes durch den Schlitz in der Segmentscheibe erforderlich ist, aufzuweisen.The disk-shaped element may be, for example, a circular disk. However, since usually only one guide slot is present, the disk-shaped element can be limited to the material saving located approximately between the pivot point and guide slot area and preferably formed approximately as a circular segment disc. Such a segment disc needs only in the vicinity of the pivot point for the strength of the connection with the mounting area sufficient amount of material and in the segment as much material as is required for the overlap of the guide slot through the slot in the segment disc.

Die Montage des Seils und der Segmentscheibe im Befestigungsbereich wird erleichtert, wenn der radiale Schlitz im scheibenförmigen Element zum Umfang hin offen ist.The mounting of the rope and the segment disc in the mounting area is facilitated when the radial slot in the disc-shaped element is open towards the periphery.

Während das scheibenförmige Element beim Justieren drehbar sein muss, damit das Aufhängeelement im Führungsschlitz bewegt werden kann, ist es vorteilhaft, wenn man es nach dem Justieren im Drehpunkt festlegen kann, so dass die Einstellung nicht durch zufällige Erschütterungen verändert wird. Dies wird bevorzugt erreicht, indem das scheibenförmige Element mit einer gegebenenfalls lösbaren Schraubverbindung im Drehpunkt befestigt wird, die nach dem Justieren angezogen wird. Die Festlegung des scheibenförmigen Elements lässt sich durch andere, dem Fachmann geläufige Maßnahmen fördern, beispielsweise durch Anrauhen der sich berührenden Flächen.While the disk-shaped element must be rotatable during adjustment so that the suspension element can be moved in the guide slot, it is advantageous if it can be fixed after adjustment in the fulcrum, so that the setting is not changed by accidental shocks. This is preferably achieved by attaching the disc-shaped element with an optionally detachable screw in the fulcrum, which is tightened after adjustment. The definition of the disk-shaped element can be determined by others, the expert promote common measures, for example by roughening the touching surfaces.

Bei der Montage der erfindungsgemäßen Hängeleuchte ist dafür Sorge zu tragen, dass das Aufhängeelement sich nicht vom Seilhalterungspunkt im Befestigungsbereich löst. Hierzu wird vorteilhaft das Aufhängeelement an dem der Leuchte zugewandten Ende mit einer Aufweitung versehen, die dicker als die Breite des Führungsschlitzes ist. Das Gewicht der Leuchte wird dann über die unteren Ränder des Führungsschlitzes auf die Aufweitung und damit auf das Aufhängeelement übertragen. Es kann hilfreich sein, die Aufweitung und den Führungsschlitz so zu gestalten, dass der Endbereich des Aufhängeelements auch unter Last leicht gleiten kann. Die Aufweitung kann beispielsweise durch einen angelöteten, angeschraubten oder aufgequetschten Nippel realisiert sein.When mounting the suspended luminaire according to the invention, care must be taken that the suspension element does not come loose from the cable support point in the fastening area. For this purpose, the suspension element is advantageously provided at the end facing the lamp with a widening, which is thicker than the width of the guide slot. The weight of the lamp is then transmitted via the lower edges of the guide slot on the expansion and thus on the suspension. It may be helpful to design the widening and guide slot so that the end portion of the hanger can easily slide under load. The expansion can be realized for example by a soldered, screwed or crushed nipple.

Bei einer bevorzugten erfindungsgemäßen Ausführungsform ist die Leuchte als Lichtband mit mindestens zwei auf eine gemeinsame Längsachse ausgerichteten aneinandergrenzenden Leuchtengehäusen ausgebildet. Dabei ist mindestens ein Befestigungsbereich im Übergangsbereich zwischen aneinandergrenzenden Leuchtengehäusen angeordnet.In a preferred embodiment of the invention, the light is designed as a light band with at least two adjacent to a common longitudinal axis adjacent luminaire housings. In this case, at least one fastening region is arranged in the transition region between adjoining luminaire housings.

In diesem Zusammenhang versteht man unter Lichtband eine Anordnung aus einer Mehrzahl von langgestreckten Leuchten, die in Richtung ihrer Längserstreckung hintereinander angeordnet sind. Diese Leuchten können beispielsweise jeweils einzelne Leuchtröhren oder auch mehrere parallel zueinander liegende Leuchtröhren aufweisen. Lichtbänder werden beispielsweise zur Beleuchtung großer Räume in Längen von bis zu 30 m und mehr installiert. Üblicherweise sind die Leuchtengehäuse an die Verwendung im Lichtband angepasst. Zur Verbindung der Leuchten im Lichtband untereinander dienen so genannte Lichtbandkupplungen, die die Endbereiche aneinander grenzender Leuchtengehäuse stützen, die Stirnwände der Leuchtengehäuse ersetzen und die elektrische Verbindung zwischen den Leuchten herstellen können. Diese Verbindungen der Leuchten untereinander können so stabil ausgeführt sein, dass man nur einen Befestigungsbereich je Leuchtengehäuse oder gar weniger benötigt. Ein solcher Befestigungsbereich wird bevorzugt an einer Lichtbandkupplung vorgesehen, weil er dann die Endbereiche zweier Leuchtengehäuse trägt.In this context, the term light band is understood to mean an arrangement of a plurality of elongated lamps which are arranged one behind the other in the direction of their longitudinal extent. For example, these luminaires may each have individual luminous tubes or else several luminous tubes lying parallel to one another. Continuous lighting strips are installed, for example, to illuminate large rooms in lengths of up to 30 m and more. The luminaire housings are usually adapted for use in the light band. To connect the lights in the light strip with each other serve so-called light band couplings, which support the end portions of adjacent luminaire housing, replace the end walls of the luminaire housing and replace the electrical Can connect between the lights. These connections of the luminaires with each other can be made so stable that you only need one mounting area per luminaire housing or even less. Such a fastening region is preferably provided on a light band coupling, because it then carries the end regions of two luminaire housings.

Ebenfalls nicht gezeigt ist das andere Ende der Hängeleuchte, das in gleicher Weise aufgehängt ist. Die Figur zeigt auch, dass das Drahtseil durch eine mit einer Schraube 11 am Leuchtengehäuse 1 befestigte Segmentscheibe 5 geführt ist, die später näher beschrieben wird. FIG. 1a shows the side view of a portion of a suspension lamp according to the invention, in which a lamp housing 1 via a suspension element, in this case a wire rope 2, not at one shown carrier, such as a ceiling or a ceiling joist suspended. Also not shown is the other end of the pendant, which is hung in the same way. The figure also shows that the wire rope is guided by a with a screw 11 attached to the lamp housing 1 segment disc 5, which will be described later in more detail.

Figur 1b zeigt eine Draufsicht des in Figur 1a dargestellten Teils der Hängeleuchte. Auf der Oberseite 4 der Leuchte ist ein Befestigungsbereich 3 markiert, in dem die Segmentscheibe 5 mit der Schraube 11 befestigt ist. FIG. 1b shows a plan view of the in FIG. 1a represented part of the suspension lamp. On the upper side 4 of the lamp, a mounting area 3 is marked, in which the segment disc 5 is fixed with the screw 11.

Figur 2 zeigt dasselbe Teil der Hängeleuchte in Schrägansicht, wiederum mit Oberseite 4 des Leuchtengehäuses 1 und Segmentscheibe 5, wobei das Drahtseil 2 durch die Segmentscheibe 5 und die Oberseite 4 in das Innere des Leuchtengehäuses geführt ist. Stirnseitig ist das Leuchtengehäuse mit einer Stirnwand 7 abgeschlossen. FIG. 2 shows the same part of the pendant in an oblique view, again with top 4 of the lamp housing 1 and segment disc 5, wherein the wire rope 2 is guided by the segment disc 5 and the top 4 in the interior of the lamp housing. The front side of the lamp housing is closed with an end wall 7.

Im Querschnitt Figur 3 sieht man, dass das Drahtseil 2 an seinem unteren Ende mit einem Nippel 6 versehen ist, der das Ende des Drahtseils im Inneren des Leuchtengehäuses hält, so dass dieses sich auf den Nippel stützt, und das Drahtseil 2 im übrigen in den Öffnungen der Segmentscheibe 5 und der Oberseite 4 beweglich bleibt.In cross section FIG. 3 it can be seen that the wire rope 2 is provided at its lower end with a nipple 6 which holds the end of the wire rope inside the lamp housing so that it rests on the nipple, and the wire rope 2 otherwise in the openings of the segment disc fifth and the top 4 remains movable.

In Figur 4 sind Details des Befestigungsbereiches 3 gezeigt, wobei die Segmentscheibe 5 abgenommen ist. In der Oberseite 4 des Leuchtengehäuses 1 ist ein Führungsschlitz 8 angebracht, durch den das Drahtseil 2 so durchgeführt ist, das es im Führungsschlitz verschiebbar ist. Eine Gewindebohrung 16 im Drehpunkt 10 ist für die Aufnahme der Schraube 11 bestimmt. Am Ende der Oberseite 4 ist neben der Stirnwand 7 eine Ausnehmung 17 angebracht, die zur Bildung eines Führungsschlitzes beiträgt, wenn zwei Leuchtengehäuse in einem Lichtband miteinander verbunden werden, wie später beschrieben werden wird.In FIG. 4 are shown details of the mounting portion 3, wherein the segment disc 5 is removed. In the top 4 of the lamp housing 1, a guide slot 8 is attached, through which the wire rope 2 is performed so that it is displaceable in the guide slot. A threaded bore 16 in the pivot point 10 is intended for receiving the screw 11. At the end of the upper side 4, a recess 17 is provided adjacent to the end wall 7, which contributes to the formation of a guide slot when two lamp housings are connected together in a light band, as will be described later.

Figur 5 zeigt den Befestigungsbereich mit der aufgelegten Segmentscheibe 5, die im Drehpunkt 10 mit der Schraube 11 zunächst drehbar befestigt ist. Das Drahtseil 2 verläuft senkrecht zur Papierebene durch den radialen Schlitz 9 und den hier von der Segmentscheibe 5 verdeckten Führungsschlitz 8. Im gezeigten Beispiel befindet sich der Drehpunkt 10 auf der Mittellinie M der Oberseite 4 des Leuchtengehäuses, während der radiale Schlitz 9 um etwa 30° von der Mittellinie abweicht. Dementsprechend ist der der Projektion des Drahtseils 2 entsprechende Seilhalterungspunkt um die Strecke a gegen die Mittellinie M verschoben. Wird nun die Segmentscheibe 5 entsprechend dem Pfeil P um den Drehpunkt 10 gedreht, beispielsweise im Uhrzeigersinn, dann wird das Drahtseil durch die Wirkung der Segmentscheibe 5 im Führungsschlitz 8 auf die Mittellinie zu bewegt. Dreht man die Segmentscheibe 5 weiter, dann kann der Seilhalterungspunkt auch auf die andere Seite der Mittellinie verschoben werden. Da das Ende des Drahtseils 2 dabei im geraden und vertikal zur Mittellinie angeordneten Führungsschlitz 8 verschoben wird, hat diese Verschiebung keine Komponente in Längsrichtung der Leuchte. Dagegen kann sich das Drahtseil 2 im radialen Schlitz 9 während der Drehbewegung relativ zum Drehpunkt 10 bewegen. FIG. 5 shows the attachment area with the applied segment disc 5, which is initially rotatably mounted in the pivot point 10 with the screw 11. The wire rope 2 extends perpendicular to the plane of the paper through the radial slot 9 and here hidden by the segment disc 5 guide slot 8. In the example shown, the pivot point 10 is located on the center line M of the top 4 of the lamp housing, while the radial slot 9 by about 30 ° deviates from the center line. Accordingly, the cable support point corresponding to the projection of the wire rope 2 is displaced by the distance a against the center line M. Now, if the segment disc 5 is rotated according to the arrow P about the pivot point 10, for example in a clockwise direction, then the wire rope is moved by the action of the segment disc 5 in the guide slot 8 to the center line. If you turn the segment disc 5 on, then the rope support point can be moved to the other side of the center line. Since the end of the wire rope 2 is thereby displaced in the straight and vertical to the center line guide slot 8, this displacement has no component in the longitudinal direction of the lamp. In contrast, the wire rope 2 can move in the radial slot 9 during the rotational movement relative to the pivot point 10.

Wenn, beispielsweise durch die Konstruktion der Leuchte, von Anfang an ein Ungleichgewicht bezüglich der Mittellinie vorhanden ist, kann der Befestigungsbereich selbstverständlich auch so vorgesehen sein, dass der Drehpunkt 10 sich entsprechend außerhalb der Mittellinie befindet.If, for example, due to the construction of the luminaire, there is an imbalance with respect to the center line from the outset, the fixing area can, of course, also be provided such that the pivot point 10 is correspondingly outside the center line.

Wenn die Hängeleuchte nach Einstellung der Segmentscheibe 5 in gewünschter Weise in die Waagerechte eingestellt worden ist, kann durch Anziehen der Schraube 11 die Segmentscheibe 5 festgelegt werden, so dass sie sich nicht mehr, beispielsweise durch Erschütterungen, verstellen kann. Sowohl die Einstellung der Segmentscheibe als auch das Anziehen der Schraube 11 kann mit einer Hand geschehen, so dass die Montage erleichtert wird.If the pendant lamp has been set in the desired manner in the horizontal direction after adjustment of the segment disc 5, the segment disc 5 can be fixed by tightening the screw 11 so that it can no longer be adjusted, for example by vibrations. Both the adjustment of the segment disc and the tightening of the screw 11 can done with one hand, so that the assembly is facilitated.

Die Figuren 6 bis 9 beschreiben eine zweite erfindungsgemäße Ausführungsform, bei der die Hängeleuchte als Lichtband gestaltet ist. Figur 6 zeigt den Verbindungsbereich zwischen zwei im Lichtband aneinandergrenzenden Leuchtengehäusen 1. Diese Leuchtengehäuse können grundsätzlich so gestaltet sein wie bei der oben beschriebenen Hängeleuchte, jedoch wird in der Regel die Stirnwand weggelassen und durch eine so genannte Lichtbandkupplung, die an den Enden der aneinanderstoßenden Leuchtengehäuse befestigt wird und diese zusammenhält, ersetzt. In diesem Fall ist nur ein Befestigungsbereich 3 im Bereich der Lichtbandkupplung erforderlich. Wiederum ist eine Segmentscheibe 5 mit einem radialen Schlitz 9 wie bei der ersten Ausführungsform vorgesehen.The FIGS. 6 to 9 describe a second embodiment of the invention, in which the pendant light is designed as a light band. FIG. 6 This luminaire housing can basically be designed as in the above-described pendant light, but usually the end wall is omitted and by a so-called light band coupling, which is attached to the ends of the abutting luminaire housing and holding them together, replacing them. In this case, only one mounting area 3 in the region of the light band coupling is required. Again, a segment disc 5 is provided with a radial slot 9 as in the first embodiment.

Figur 7 zeigt einen Längsschnitt durch den Verbindungsbereich des Lichtbands mit dem Drahtseil 2, auf dessen Nippel 6 die Oberseiten 4 der Leuchtengehäuse 1 ruhen. Die Segmentscheibe 5 ist um die Schraube 11 drehbar. FIG. 7 shows a longitudinal section through the connection region of the light band with the wire rope 2, on the nipple 6, the tops 4 of the lamp housing 1 rest. The segment disc 5 is rotatable about the screw 11.

In Figur 8 ist der Befestigungsbereich, ähnlich wie in Figur 4 ohne die Segmentscheibe 5 dargestellt. Die Ausnehmungen 17 der aneinandergrenzenden Oberseiten 4 der Leuchtengehäuse 1 bilden zusammen den Führungsschlitz für das Ende des Drahtseil 2. Die für die Verwendung als Einzelleuchte vorgesehenen Führungsschlitze 8 werden in diesem Fall nicht benutzt. Dagegen dient die Gewindebohrung 16 im Drehpunkt 10 auch hier zur Befestigung der Segmentscheibe 5.In FIG. 8 is the attachment area, similar to in FIG. 4 without the segment disc 5 shown. The recesses 17 of the adjoining tops 4 of the lamp housing 1 together form the guide slot for the end of the wire 2. The intended for use as a single lamp guide slots 8 are not used in this case. In contrast, the threaded hole 16 in the pivot point 10 also serves here for fastening the segment disc. 5

Figur 9 zeigt den Befestigungsbereich 3 für die Lichtbandverbindung mit aufgelegter Segmentscheibe 5. Die Wirkungsweise ist hier dieselbe wie zu Figur 5 erläutert. An den Enden des Lichtbandes kann die Aufhängung so ausgebildet werden, wie oben für die Einzelleuchte beschrieben. FIG. 9 shows the mounting portion 3 for the light band connection with applied segment disc 5. The operation is the same here as to FIG. 5 explained. At the ends of the light band, the suspension can be formed as described above for the individual light.

Für den Fachmann ist ersichtlich, dass der Schutzbereich und der Gedanke der Erfindung nicht nur auf eine Hängeleuchte an sich beschränkt ist, sondern auch als Nachrüstsatz für bestehende Leuchten angeboten werden kann.It will be apparent to those skilled in the art that the scope and spirit of the invention is not limited solely to a pendant light per se, but may be offered as a retrofit kit for existing lights.
