Description

Die Erfindung betrifft eine Pendelleuchte mit einem länglichen Trägerelement und einer, an dem Trägerelement angeordneten Lichtquelle zur Erzeugung einer nach oben gerichteten indirekten Beleuchtung.The invention relates to a pendant lamp with an elongated carrier element and a, arranged on the support element light source for generating an upward indirect lighting.

Aus der DE 10 2008 014 317 A1 ist eine solche Pendelleuchte bekannt. Zur Erzeugung der indirekten Beleuchtung dienen dabei Entladungslampen, die - mit Bezug auf die Längsachse der Leuchte - zu beiden Seiten angeordnet sind.From the DE 10 2008 014 317 A1 is such a pendant lamp known. To generate the indirect illumination serve discharge lamps, which - are arranged on both sides - with respect to the longitudinal axis of the lamp.

Aus der EP 0 469 179 ist eine Pendelleuchte mit einem länglichen Trägerelement und mehreren, in unterschiedlichen Höhen angeordneten Lichtquellen bekannt.From the EP 0 469 179 is a pendant lamp with an elongated support member and a plurality of light sources arranged at different heights known.

Aus der DE 20 2011 051 094 U1 und aus der US 3,214,580 sind weitere längliche Pendelleuchte bekannt.From the DE 20 2011 051 094 U1 and from the US 3,214,580 are more elongated pendant lamp known.

Der Erfindung liegt die Aufgabe zugrunde, eine entsprechende, verbesserte Pendelleuchte anzugeben. Insbesondere soll die Pendelleuchte bessere Eigenschaften mit Bezug auf den Zusammenbau der Leuchte aufweisen.The invention has for its object to provide a corresponding, improved pendant lamp. In particular, the pendant should have better properties with respect to the assembly of the lamp.

Diese Aufgabe wird gemäß der Erfindung mit dem in dem unabhängigen Anspruch genannten Gegenstand gelöst. Besondere Ausführungsarten der Erfindung sind in den abhängigen Ansprüchen angegeben.This object is achieved according to the invention with the object mentioned in the independent claim. Particular embodiments of the invention are indicated in the dependent claims.

Gemäß der Erfindung ist eine Pendelleuchte vorgesehen, die ein längliches Trägerelement aufweist, das sich entlang einer Längsachse erstreckt, sowie eine, an dem Trägerelement angeordnete, Lichtquelle zur Erzeugung einer nach oben gerichteten indirekten Beleuchtung. Die Lichtquelle weist dabei einen ersten Abschnitt auf, der sich mit Bezug auf die Längsachse über einen ersten Längsbereich erstreckt, sowie einen zweiten Abschnitt, der sich mit Bezug auf die Längsachse über einen zweiten Längsbereich erstreckt, wobei der zweite Abschnitt auf einem höheren Niveau angeordnet ist als der erste Abschnitt und dabei der erste Abschnitt und der zweite Abschnitt als Teile einer Baueinheit ausgestaltet sind.According to the invention, a pendant lamp is provided which has an elongate support element which extends along a longitudinal axis, and a light source arranged on the support element for producing an upward indirect illumination. The light source in this case has a first portion which extends with respect to the longitudinal axis over a first longitudinal region, and a second portion which extends with respect to the longitudinal axis over a second longitudinal region, wherein the second portion is arranged at a higher level as the first portion and thereby the first portion and the second portion are designed as parts of a structural unit.

Die Pendelleuchte umfasst weiterhin einen dritten Abschnitt, der sich entsprechend über einen dritten Längsbereich erstreckt, wobei sich die drei Längsbereiche in einerThe pendant lamp further comprises a third section, which extends over a corresponding third longitudinal area, wherein the three longitudinal areas in one

Reihe entlang der Längsachse erstrecken und der zweite Längsbereich zwischen dem ersten Längsbereich und dem dritten Längsbereich angeordnet ist.Row along the longitudinal axis and the second longitudinal region between the first longitudinal region and the third longitudinal region is arranged.

Durch diese Ausgestaltung lässt sich erzielen, dass die Lichtquelle zur Erzeugung der nach oben gerichteten indirekten Beleuchtung besonders einfach montiert werden kann und auch demontiert werden kann. Besonders geeignet lässt sich dabei die Baueinheit und damit die Lichtquelle - mit Bezug auf eine Ebene normal zu der Längsachse der Pendelleuchte - mittig anordnen. Die Pendelleuchte kann somit schmaler gebaut werden. Dadurch, dass der zweite Abschnitt der Lichtquelle auf einem höheren Niveau angeordnet ist als der erste Abschnitt, lässt sich besonders vorteilhaft unter dem zweiten Abschnitt ein weiteres Bauelement der Pendelleuchte anordnen, besonders geeignet ein Betriebsgerät für die Lichtquelle.By means of this configuration, it is possible to achieve that the light source for producing the upward indirect illumination can be mounted particularly easily and can also be dismounted. The assembly and thus the light source - with respect to a plane normal to the longitudinal axis of the pendant lamp - can be arranged centrally in a particularly suitable manner. The pendant light can thus be made narrower. The fact that the second section of the light source is arranged at a higher level than the first section, can be particularly advantageous under the second section to arrange another component of the pendant light, particularly suitable for a control device for the light source.

Vorzugsweise ist die Pendelleuchte derart gestaltet, dass - wenn sich die Pendelleuchte in einem abgehängten Zustand befindet - die Baueinheit von der restlichen Pendelleuchte, insbesondere von dem Trägerelement, reversibel getrennt werden kann, ohne dass hierzu die Pendelleuchte aus dem abgehängten Zustand in einen nicht abgehängten Zustand verbracht werden muss. Auf diese Weise lässt sich die Baueinheit mit der Lichtquelle besonders handhabungsfreundlich - nämlich ohne, dass die Pendelleuchte hierfür abgenommen werden müsste - von der restlichen Pendelleuchte demontieren und auch wieder an der restlichen Pendelleuchte montieren. Dies kann beispielsweise bei einem Austausch der Baueinheit relevant sein, durch den der Pendelleuchte andere Eigenschaften hinsichtlich der indirekten Beleuchtung verliehen werden sollen oder bei einem Austausch des Betriebsgeräts.Preferably, the pendant lamp is designed such that - when the pendant light is in a suspended state - the unit from the remaining pendant light, in particular from the support element, can be reversibly separated, without requiring the pendant light from the suspended state in a non-suspended state must be spent. In this way, the unit with the light source is particularly easy to handle - namely, without that the pendant lamp would have to be removed for this - disassemble the rest of the pendant and also mount again to the rest of the pendant lamp. This may be relevant, for example, in the case of an exchange of the structural unit, by means of which the pendant luminaire is to be given other properties with regard to the indirect lighting or when the operating device is replaced.

Vorzugsweise ist die Baueinheit mechanisch lediglich über eine Schraubverbindung mit der restlichen Pendelleuchte verbunden, wobei die Schraubverbindung vorzugsweise wenigstens zwei Schrauben umfasst. Eine Schraubverbindung ist in der Handhabung besonders einfach. Zudem lässt sich durch die Schraubverbindung besonders geeignet eine elektrische Erdungsverbindung zwischen der Baueinheit und der restlichen Pendelleuchte herstellen. Wenn die Schraubverbindung wenigstens zwei Schrauben umfasst, sind zur Demontage der Baueinheit zwei voneinander unabhängige Handlungen erforderlich. Hierdurch ist die Gefahr für einen Benutzer reduziert, einen Stromschlag durch eine ungewollte Berührung der Lichtquelle zu erhalten; zudem lassen sich hierdurch relevante Sicherheitsvorschriften einhalten.Preferably, the assembly is mechanically connected only via a screw with the rest of the pendant lamp, wherein the screw preferably comprises at least two screws. A screw is particularly easy to use. In addition, an electrical ground connection between the assembly and the remaining pendant lamp can be produced by the screw connection particularly suitable. If the screw connection comprises at least two screws, disassembly of the assembly requires two independent actions. As a result, the risk for a user is reduced to receive an electric shock by accidental contact with the light source; In addition, relevant safety regulations can be complied with.

Vorzugsweise ist die Baueinheit elektrisch lediglich über eine Steckverbindung mit der restlichen Pendelleuchte verbunden. Auf diese Weise lässt sich die elektrische Verbindung zwischen der Baueinheit und der restlichen Pendelleuchte beim Zusammenbau der Pendelleuchte oder bei einem Austausch der Baueinheit oder des Betriebsgeräts besonders einfach herstellen bzw. lösen.Preferably, the assembly is electrically connected only via a plug connection with the rest of the pendant lamp. In this way, the electrical connection between the unit and the remaining pendant lamp when assembling the pendant lamp or when replacing the unit or the operating device can be particularly easy to establish or solve.

Vorzugsweise umfasst die Baueinheit ein erstes Profilelement und ein zweites Profilelement, wobei der erste Abschnitt der Lichtquelle an dem ersten Profilelement gehalten angeordnet ist und der zweite Abschnitt der Lichtquelle an dem zweiten Profilelement gehalten angeordnet ist. Hierdurch ist ein besonders einfacher Aufbau der Baueinheit ermöglicht.Preferably, the assembly comprises a first profile element and a second profile element, wherein the first portion of the light source is arranged held on the first profile element and the second portion of the light source is held held on the second profile element. This allows a particularly simple construction of the unit.

Dabei ist weiterhin vorzugsweise das erste Profilelement parallel zu der Längsachse ausgerichtet angeordnet und auch das zweite Profilelement parallel zu der Längsachse ausgerichtet angeordnet, wobei vorzugsweise das erste Profilelement dieselbe Querschnitt-Form aufweist wie das zweite Profilelement. Hierdurch ist die Herstellung der Pendelleuchte vereinfacht. Zudem lässt sich die Baueinheit hierdurch besonders geeignet modular aufbauen, wobei jedes Modul ein Profilelement umfasst.In this case, furthermore, preferably the first profile element is arranged aligned parallel to the longitudinal axis and arranged the second profile element parallel to the longitudinal axis, wherein preferably the first profile element has the same cross-sectional shape as the second profile element. As a result, the production of the pendant lamp is simplified. In addition, the unit can thereby be particularly suitable modular build, each module comprises a profile element.

Weiterhin vorzugsweise weist die Baueinheit außerdem ein Verbindungselement auf, das das erste Profilelement mit dem zweiten Profilelement verbindet. Auf diese Weise lässt sich insbesondere das erste Profilelement mit dem zweiten Profilelement mechanisch und auch elektrisch fix verbinden, so dass für die elektrische Verbindung zwischen dem ersten Abschnitt und dem zweiten Abschnitt der Lichtquelle insbesondere keine elektrische Steckverbindung vorgesehen werden muss.Furthermore, preferably, the assembly further comprises a connecting element which connects the first profile element with the second profile element. In this way, in particular the first profile element with the second profile element mechanically and electrically fixed, so that in particular no electrical connector must be provided for the electrical connection between the first portion and the second portion of the light source.

Vorzugsweise weist die Pendelleuchte außerdem ein Abhänge-Element zur Halterung der Pendelleuchte an einem Leuchtenträger, beispielsweise einer Decke, auf, wobei das Verbindungselement eine Ausnehmung aufweist und das Abhänge-Element die Ausnehmung durchsetzend angeordnet ist. Auf diese Weise lässt sich das Abhänge-Element mit Bezug auf die Längsachse an einer Stelle anordnen, an der es die nach oben gerichtete Lichtabgabe der Lichtquelle zur Erzeugung der indirekten Beleuchtung besonders wenig beeinträchtigt. Wenn dabei die Ausnehmung des Verbindungselements U-förmig ist, lässt sich erzielen, dass die Baueinheit zur Demontage mit Bezug auf die Längsachse besonders einfach über eine seitliche Bewegung von der restlichen Pendelleuchte getrennt werden kann.Preferably, the pendant lamp also has a suspension element for mounting the pendant light to a light carrier, such as a ceiling, on, wherein the connecting element has a recess and the suspension element is arranged passing through the recess. In this way, the suspension element can be arranged with respect to the longitudinal axis at a location where it particularly affects the upward light output of the light source for generating the indirect illumination. In this case, if the recess of the connecting element is U-shaped, it can be achieved that the assembly for disassembly with respect to the longitudinal axis can be separated particularly easily by a lateral movement of the remaining pendant lamp.

Vorzugsweise weisen das erste Profilelement und das zweite Profilelement jeweils wenigstens einen Schraubkanal auf, vorzugsweise jeweils wenigstens zwei Schraubkanäle, der bzw. die zur Aufnahme jeweils eines Verbindungsmittels, beispielsweise einer Schraube, zur Befestigung des Verbindungselements gestaltet ist bzw. sind. Dies ist herstellungstechnisch vorteilhaft. Wenn jeweils zwei Schraubkanäle vorgesehen sind, lässt sich wiederum geeignet erzielen, dass zwei voneinander unabhängige Handlungen erforderlich sind, um einen Zugang zu einem, durch die Lichtquelle gebildeten Hochvoltbereich zu eröffnen.Preferably, the first profile element and the second profile element each have at least one screw, preferably at least two screw channels, which is or are designed to receive a respective connecting means, such as a screw, for fastening the connecting element. This is manufacturing technology advantageous. In turn, if two screw channels are provided, it is possible to appropriately achieve that two independent actions are required in order to open access to a high-voltage region formed by the light source.

Eine besonders geeignete Ausgestaltung ist ermöglicht, wenn das erste Profilelement im Querschnitt U-förmig ist und der erste Abschnitt der Lichtquelle innerhalb eines, durch die U-Form gebildeten Kanals an dem ersten Profilelement gehalten angeordnet ist. Dabei weist weiterhin vorzugsweise die Baueinheit weiterhin ein Abdeckelement auf, das derart an dem ersten Profilelement gehalten angeordnet ist, dass es den Kanal und den darin angeordneten ersten Abschnitt der Lichtquelle abdeckt. Durch das Abdeckelement lässt sich die Gefahr einer ungewollten Berührung der Lichtquelle verringern und zudem ein Staub- und Schlagschutz der Lichtquelle bewirken.A particularly suitable embodiment is made possible if the first profile element is U-shaped in cross-section and the first section of the light source is within a, arranged by the U-shaped channel is held held on the first profile element. In this case, the assembly further preferably further comprises a cover member, which is arranged held on the first profile element such that it covers the channel and the first portion of the light source arranged therein. By the cover can reduce the risk of accidental contact with the light source and also cause a dust and impact protection of the light source.

Vorzugweise weist das erste Profilelement Führungselemente zur Halterung des Abdeckelements auf, die insbesondere parallel zu der Längsachse verlaufend gestaltet sind. Hierdurch lässt sich erzielen, dass sich das Abdeckelement nur durch eine Translationsbewegung in Richtung der Längsachse wie vorgesehen mit dem ersten Profilelement verbinden lässt. Die Gefahr eines ungewollten Zugangs zu der Lichtquelle ist hierdurch weiterhin verringert.Preferably, the first profile element on guide elements for holding the cover, which are designed to extend in particular parallel to the longitudinal axis. This makes it possible to achieve that the cover element can be connected as intended to the first profile element only by means of a translatory movement in the direction of the longitudinal axis. The risk of unwanted access to the light source is thereby further reduced.

Weiterhin vorzugsweise weist die Baueinheit außerdem ein Endabdeckungselement auf, das zur Lagesicherung des Abdeckelements mit Bezug auf eine Bewegung parallel zu der Längsachse ausgestaltet ist. Durch das Endabdeckungselement lässt sich erzielen, dass die Abdeckung praktisch nicht versehentlich von dem ersten Profilelement getrennt werden kann.Further preferably, the assembly further comprises an end cover member configured to secure the position of the cover member with respect to a movement parallel to the longitudinal axis. By the end cover element can be achieved that the cover can not be accidentally separated from the first profile element practically.

Herstellungstechnisch vorteilhaft weist weiterhin vorzugweise das zweite Profilelement dieselbe Querschnitt-Form auf wie das erste Profilelement, wobei vorzugsweise die Baueinheit außerdem ein weiteres Abdeckelement aufweist, das auf dieselbe Weise an dem zweiten Profilelement gehalten angeordnet ist, wie das zuerst genannte Abdeckelement an dem ersten Profilelement.In terms of manufacturing technology, the second profile element preferably also has the same cross-sectional shape as the first profile element, wherein preferably the structural unit also has a further covering element which is held in the same manner on the second profile element as the first-mentioned covering element on the first profile element.

Fig. 1 zeigt eine perspektivische Skizze eines Ausführungsbeispiels einer erfindungsgemäßen Pendelleuchte, im Folgenden auch kurz als Leuchte bezeichnet. Fig. 1 shows a perspective sketch of an embodiment of a pendant lamp according to the invention, hereinafter also referred to briefly as a lamp.

Die Leuchte weist ein längliches Trägerelement 1 auf, das sich entlang einer Längsachse L erstreckt. Vorzugsweise ist die Leuchte insgesamt länglich, wobei die Längsachse L eine Hauptachse der Leuchte bildet.The luminaire has an elongated carrier element 1 which extends along a longitudinal axis L. Preferably, the lamp is generally elongate, wherein the longitudinal axis L forms a major axis of the lamp.

Insbesondere kann die Leuchte wenigstens ein Abhänge-Element 5 aufweisen, beispielsweise in Form eines Seils, eines Kabels, oder eines Pendels oder dergleichen, gegebenenfalls mit daran befestigten Halteelementen zur mechanischen Verbindung mit dem Trägerelement 1 einerseits und einem Leuchtenträger andererseits, wie beispielsweise einer Raumdecke. Bevorzugt weist die Pendelleuchte genau zwei Abhänge-Elemente 5,5' auf, die mit Bezug auf die Längsachse L so an dem Trägerelement 1 angeordnet sind, dass sie von dem jeweils nächsten Längsendpunkt der Leuchte jeweils gleichweit beabstandet sind.In particular, the luminaire may have at least one suspension element 5, for example in the form of a cable, a cable or a pendulum or the like, optionally with retaining elements attached thereto for mechanical connection to the support element 1 on the one hand and a light support on the other hand, such as a ceiling. Preferably, the pendant lamp exactly two suspension elements 5,5 ', which are arranged with respect to the longitudinal axis L on the support member 1, that they are equidistant from each next longitudinal end point of the lamp.

Weiterhin weist die Leuchte eine, in separierter Form in Fig. 2 perspektivisch skizziert gezeigte Baueinheit 3 auf. Die Baueinheit 3 ist vorzugsweise insgesamt länglich gestaltet, wobei sie sich mit ihrer Längsachse parallel zu der Längsachse L erstreckt.Furthermore, the lamp has a, in separated form in Fig. 2 Outlined in perspective on 3 unit. The assembly 3 is preferably designed to be generally elongate, extending with its longitudinal axis parallel to the longitudinal axis L.

Fig. 3 zeigt einen, normal zu der Längsachse L gerichteten Querschnitt der Baueinheit 3. Zur Erzeugung einer nach oben gerichteten indirekten Beleuchtung weist die Leuchte eine, an dem Trägerelement 1 angeordnete Lichtquelle 2 auf. Die Lichtquelle 2 kann insbesondere mehrere LEDs (LED: Licht emittierende Diode) aufweisen. Die Lichtquelle 2 umfasst einen ersten Abschnitt 21, der sich mit Bezug auf die Längsachse L über einen ersten Längsbereich L1 erstreckt, sowie einen zweiten Abschnitt 22, der sich mit Bezug auf die Längsachse L über einen zweiten Längsbereich L2 erstreckt. Dabei ist der zweite Abschnitt 21 auf einem höheren Niveau angeordnet als der erste Abschnitt 22. Fig. 3 shows a, normal to the longitudinal axis L directed cross-section of the unit 3. To produce an upward indirect lighting, the lamp has a, arranged on the support member 1 light source 2. The light source 2 may in particular have a plurality of LEDs (LED: light-emitting diode). The light source 2 comprises a first portion 21 which extends with respect to the longitudinal axis L over a first longitudinal region L1 , and a second portion 22 which extends with respect to the longitudinal axis L via a second longitudinal region L2 . In this case, the second section 21 is arranged at a higher level than the first section 22.

Der erste Abschnitt 21 und der zweite Abschnitt 22 sind dabei als Teile der Baueinheit 3 ausgestaltet. Insbesondere kann der erste Abschnitt 21 mehrere LEDs aufweisen, die auf einer ersten Platine 81 angeordnet sind und der zweite Abschnitt 22 weitere mehrere LEDs, die auf einer zweiten Platine 82 angeordnet sind. Dabei können die mehreren LEDs beispielsweise jeweils längs einer Geraden angeordnet sein, die sich parallel zu der Längsachse L erstreckt.The first section 21 and the second section 22 are designed as parts of the unit 3. In particular, the first section 21 may comprise a plurality of LEDs which are arranged on a first circuit board 81 and the second section 22 further a plurality of LEDs disposed on a second board 82. For example, the plurality of LEDs may each be arranged along a straight line which extends parallel to the longitudinal axis L.

Bei dieser Form der Lichtquelle kann typischerweise vorgesehen sein, dass eine betreffende Platine mit einer Hochvoltspannung beaufschlagt ist. Daher ist es zweckmäßig, wenn die Leuchte derart ausgestaltet ist, dass ein Benutzer der Leuchte vor einer versehentlichen Berührung der Platine möglichst geschützt ist.In this form of the light source can typically be provided that a relevant board is subjected to a high voltage. Therefore, it is useful if the lamp is designed such that a user of the lamp is protected as possible from accidental contact with the board.

Vorzugsweise ist die Lichtquelle 2 insgesamt als Teil der Baueinheit 3 ausgestaltet. Im gezeigten Beispiel weist die Lichtquelle 2 außer dem ersten Abschnitt 21 und dem zweiten Abschnitt 22 noch einen dritten Abschnitt auf, der sich entsprechend über einen dritten Längsbereich L3 erstreckt, wobei sich die drei Längsbereiche L1, L2, L3 in einer Reihe entlang der Längsachse L erstrecken und der zweite Längsbereich L2 zwischen dem ersten Längsbereich L1 und dem dritten Längsbereich L3 angeordnet ist. Die Lichtquelle 3 kann dabei aus den genannten drei Abschnitten bestehen, also insbesondere keinen weiteren Abschnitt mehr aufweisen. Der dritte Abschnitt ist vorzugsweise analog oder baugleich zu dem ersten Abschnitt 21 gestaltet.Preferably, the light source 2 is designed as a whole as part of the unit 3. In the example shown, the light source 2, in addition to the first section 21 and the second section 22, has a third section which extends correspondingly over a third longitudinal area L3 , wherein the three longitudinal areas L1 , L2 , L3 are arranged in a row along the longitudinal axis L and the second longitudinal region L2 is arranged between the first longitudinal region L1 and the third longitudinal region L3 . The light source 3 may consist of the three sections mentioned, so in particular have no further section. The third section is preferably designed analogously or structurally to the first section 21.

Beim gezeigten Beispiel ist ein erstes Abhänge-Element 5 der genau zwei Abhänge-Elemente 5,5' zwischen dem ersten Abschnitt 21 und dem zweiten Abschnitt 22 der Lichtquelle 2 am Trägerelement 1 angreifend angeordnet und das entsprechend zweite Abhänge-Element 5' zwischen dem zweiten Abschnitt 22 und dem dritten Abschnitt der Lichtquelle 2 am Trägerelement 1 angreifend. Dabei ist die Gestaltung allgemeiner insbesondere derart, dass das wenigstens eine Abhänge-Element 5,5' nicht an der Baueinheit 3 angreift. Hierdurch lässt sich die Baueinheit 3 von der restlichen Leuchte trennen, ohne dass das wenigstens eine Abhänge-Element 5,5' von der Leuchte getrennt werden müsste. Vorzugsweise greift das wenigstens eine Abhänge-Element 5, 5' unmittelbar am Trägerelement 1 an.In the example shown, a first suspension element 5 of exactly two suspension elements 5,5 'between the first portion 21 and the second portion 22 of the light source 2 on the support member 1 is arranged attacking and the corresponding second suspension element 5' between the second Section 22 and the third portion of the light source 2 on the support element 1 attacking. In this case, the design is more general in particular such that the at least one suspension element 5, 5 'does not engage the structural unit 3. As a result, the unit 3 can be separated from the rest of the lamp without the at least one suspension element should be 5,5 'separated from the lamp. Preferably, the at least one suspension element 5, 5 'engages directly on the carrier element 1.

Wie bereits erwähnt, ist der zweite Abschnitt 22 der Lichtquelle 2 auf einem höheren Niveau angeordnet als der erste Abschnitt 21. Insbesondere kann die Gestaltung derart sein, dass die LEDs des ersten Abschnitts 21 höher gelegen angeordnet sind als die LEDs des zweiten Abschnitts 22. Dies ist in Fig. 1 durch die Lage der eingezeichneten Längsachse L sowie eine hierzu parallele, höher gelegene, gestrichelt skizzierte, Gerade G angedeutet. Die Längsachse L ist auf einem ersten Niveau skizziert, auf dem die LEDs des ersten Abschnitts 21 der Lichtquelle 2 angeordnet sind und die Gerade G auf einem zweiten Niveau, auf dem die LEDs des zweiten Abschnitts 22 der Lichtquelle 2 angeordnet sind. Dabei liegt das zweite Niveau um einen Höhenversatz Δh höher als das erste Niveau. Der Höhenversatz Δh kann dabei beispielsweise zwischen 1 cm und 10 cm betragen.As already mentioned, the second portion 22 of the light source 2 is disposed at a higher level than the first portion 21. Specifically, the configuration may be such that the LEDs of the first portion 21 are located higher than the LEDs of the second portion 22. This is in Fig. 1 indicated by the position of the drawn longitudinal axis L and a parallel thereto, higher, dashed outlined, straight line G. The longitudinal axis L is sketched on a first level, on which the LEDs of the first section 21 of the light source 2 are arranged and the straight line G at a second level, on which the LEDs of the second portion 22 of the light source 2 are arranged. In this case, the second level is higher by a height offset Δ h than the first level. The height offset Δ h can be, for example, between 1 cm and 10 cm.

Durch diese höhenversetze Anordnung lässt sich unter dem zweiten Abschnitt 22 der Lichtquelle 2 vorteilhaft ein Bauraum gewinnen, in dem vorzugsweise ein Betriebsgerät der Leuchte, wie etwa einen Konverter, beispielsweise zur Stromversorgung der Lichtquelle 2, angeordnet sein kann oder andere elektrische Komponenten der Leuchte angeordnet sein können.By this height-offset arrangement can be under the second portion 22 of the light source 2 advantageously gain a space in which preferably an operating device of the lamp, such as a converter, for example, for powering the light source 2, may be arranged or other electrical components of the lamp may be arranged can.

Dadurch, dass der erste Abschnitt 21 der Lichtquelle 2 und der zweite Abschnitt 22 der Lichtquelle 2 - und gegebenenfalls vorzugsweise auch der dritte Abschnitt der Lichtquelle 2 bzw. die gesamte Lichtquelle 2 - als Teile der Baueinheit 3 gestaltet sind, lässt sich die Lichtquelle 2 besonders einfach von der restlichen Leuchte demontieren, insbesondere, ohne dass die Leuchte hierzu abgehängt werden müsste. Entsprechend lässt sich die Baueinheit 3 auch wieder an der entsprechend abgehängten restlichen Leuchte montieren. Somit ist die Handhabung der Leuchte, insbesondere mit Bezug auf eine Montage und Demontage der Lichtquelle 2 bzw. der Baueinheit 3 erleichtert.Characterized in that the first portion 21 of the light source 2 and the second portion 22 of the light source 2 - and possibly also the third portion of the light source 2 and the entire light source 2 - are designed as parts of the unit 3, the light source 2 can be particularly simply disassemble the rest of the lamp, in particular, without the lamp would have to be suspended for this purpose. Accordingly, the unit 3 can also be mounted again on the corresponding suspended remaining light. Thus, the handling of the lamp, in particular with respect to a mounting and dismounting of the light source 2 and the unit 3 is facilitated.

Beim gezeigten Beispiel ist die Leuchte insbesondere derart gestaltet, dass - wenn sich die Leuchte in einem abgehängten Zustand befindet - die Baueinheit 3 von der restlichen Leuchte, insbesondere von dem Trägerelement 1, reversibel getrennt werden kann, ohne dass hierzu die Pendelleuchte aus dem abgehängten Zustand in einen nicht abgehängten Zustand verbracht werden muss. Hierzu ist die Baueinheit 3 vorteilhaft mechanisch lediglich über eine Schraubverbindung mit der restlichen Leuchte, hier mit dem Trägerelement 1, verbunden. Im gezeigten Beispiel weist die Baueinheit 3 hierfür an ihren beiden Längsendbereichen jeweils ein Angriffselement für eine Schraube auf, beispielsweise eine erste Durchführungsöffnung 91 an einem ersten Längsendbereich der Baueinheit 3 und eine zweite Durchführungsöffnung 92 an dem hierzu gegenüberliegenden, zweiten Längsendbereich der Baueinheit 3.In the example shown, the lamp is in particular designed such that - when the lamp is in a suspended state - the unit 3 can be reversibly separated from the rest of the lamp, in particular from the support member 1, without requiring the pendant lamp from the suspended state must be spent in a non-suspended state. For this purpose, the assembly 3 is advantageous mechanically only via a screw with the rest of the light, here with the support member 1, respectively. In the example shown, the structural unit 3 has at its two longitudinal end regions in each case an engagement element for a screw, for example a first passage opening 91 at a first longitudinal end area of the unit 3 and a second passage opening 92 at the second longitudinal end area of the unit 3 opposite thereto.

Die Schraubverbindung ist vorzugsweise so gestaltet, dass über sie eine elektrische Erdungsverbindung zwischen der Baueinheit 3 und der restlichen Leuchte bzw. dem Trägerelement 1 gebildet ist. Die Schraubverbindung umfasst vorzugsweise genau zwei Schrauben; somit müssen zur Demontage der Baueinheit 3 zwei Schrauben gelöst werden - es sind also zwei voneinander unabhängige Handlungen erforderlich. Hierdurch ist die Gefahr vermindert, dass ungewollt ein Zugang zu der Lichtquelle 2 bzw. zu einer der Platinen 81, 82 gebildet wird; somit ist das Risiko einer Verletzung eines Benutzers durch einen Stromschlag und/oder einer Beschädigung der Lichtquelle 2 verringert.The screw connection is preferably designed such that it forms an electrical ground connection between the structural unit 3 and the remaining luminaire or the carrier element 1. The screw connection preferably comprises exactly two screws; thus have to disassemble the unit 3 solved two screws become two independent actions are required. This reduces the risk that unintentionally an access to the light source 2 or to one of the boards 81, 82 is formed; Thus, the risk of injury to a user due to electric shock and / or damage to the light source 2 is reduced.

Vorzugsweise ist die Leuchte so gestaltet, dass die Baueinheit 3 elektrisch lediglich über eine (in den Figuren nicht gezeigte) Steckverbindung mit der restlichen Leuchte verbunden ist. Auf diese Weise lässt sich insbesondere vermeiden, dass jeder Abschnitt der Lichtquelle 2 gesondert elektrisch mit der restlichen Leuchte verbunden werden muss. Hierdurch ist die Handhabung mit Bezug auf die Demontage und Montage der Baueinheit 3 weiterhin erleichtert.Preferably, the lamp is designed so that the assembly 3 is electrically connected only via a (not shown in the figures) connector with the rest of the lamp. In this way, it can be avoided, in particular, that each section of the light source 2 has to be electrically connected separately to the rest of the luminaire. As a result, the handling with respect to the disassembly and assembly of the unit 3 is further facilitated.

In Fig. 4 ist der erste Längsendbereich der Baueinheit 3 als perspektivische Ansicht von schräg oben skizziert; Fig. 5 zeigt eine entsprechende Skizze bei Ansicht von schräg unten.In Fig. 4 the first longitudinal end region of the structural unit 3 is sketched as a perspective view obliquely from above; Fig. 5 shows a corresponding sketch when viewed from diagonally below.

Herstellungstechnisch vorteilhaft umfasst die Baueinheit 3 ein erstes Profilelement 31 und ein zweites Profilelement 32, wobei der erste Abschnitt 21 der Lichtquelle 2 an dem ersten Profilelement 31 gehalten angeordnet ist und der zweite Abschnitt 22 der Lichtquelle 2 an dem zweiten Profilelement 32 gehalten angeordnet ist. Diese Profilelemente 31, 32 sind dabei jeweils parallel zu der Längsachse L ausgerichtet angeordnet. Vorzugsweise ist das zweite Profilelement 32 entsprechend um den Höhenversatz Δh höher angeordnet, als das erste Profilelement 31.In terms of manufacturing technology, the structural unit 3 comprises a first profile element 31 and a second profile element 32, the first section 21 of the light source 2 being held on the first profile element 31 and the second section 22 of the light source 2 being held on the second profile element 32. These profile elements 31, 32 are arranged in each case aligned parallel to the longitudinal axis L. Preferably, the second profile element 32 is arranged corresponding to the height offset Δ h higher than the first profile element 31st

Im gezeigten Beispiel weist die Baueinheit 3 weiterhin ein entsprechendes drittes Profilelement 33 auf, wobei der dritte Abschnitt der Lichtquelle 2 an dem dritten Profilelement 33 analog gehalten angeordnet ist. Das dritte Profilelement 33 ist vorzugsweise auf demselben Niveau angeordnet wie das erste Profilelement 31.In the example shown, the assembly 3 further comprises a corresponding third profile element 33, wherein the third portion of the light source 2 is arranged analogously held on the third profile element 33. The third profile element 33 is preferably arranged at the same level as the first profile element 31.

Durch jedes der Profilelemente 31, 32, 33 kann ein "Modul" der Baueinheit 3 gebildet sein. Das zweite Profilelement 32 ist vorzugsweise - wie in den Figuren angedeutet - länger ausgebildet als das erste Profilelement 31 und das dritte Profilelement 33. Das erste Profilelement 31 und das dritte Profilelement 33 sind vorzugsweise gleichlang ausgebildet.Through each of the profile elements 31, 32, 33, a "module" of the assembly 3 may be formed. The second profile element 32 is preferably - as indicated in the figures - formed longer than the first profile element 31 and the third profile element 33. The first profile element 31 and the third profile element 33 are preferably formed equal length.

Allgemeiner formuliert kann die Baueinheit 3 für jeden Abschnitt der Lichtquelle 2 jeweils ein entsprechendes Profilelement 31, 32, 33 aufweisen.More generally, the assembly 3 may comprise a respective profile element 31, 32, 33 for each section of the light source 2.

Eine besonders einfache Ausführung lässt sich erzielen, wenn das erste Profilelement 31 und das zweite Profilelement 32 bzw. alle Profilelemente der Baueinheit 3 dieselbe Querschnitt-Form aufweisen.A particularly simple embodiment can be achieved if the first profile element 31 and the second profile element 32 or all profile elements of the structural unit 3 have the same cross-sectional shape.

Beim gezeigten Ausführungsbeispiel weist die Leuchte zwei vertikale Seitenwände 11 auf, die sich längs der Längsachse L erstrecken und die insbesondere als Teile des Trägerelements 1 gestaltet sein können; dabei ist die Anordnung derart, dass die Profilelemente 31, 32, 33 der Baueinheit 3 zwischen den beiden Seitenwänden 11 angeordnet sind, insbesondere derart, dass zwischen den Profilelementen 31, 32, 33 einerseits und den angrenzenden Seitenwänden 11 andererseits Abstände gebildet sind, die kleiner als 2 mm sind.In the embodiment shown, the lamp has two vertical side walls 11 which extend along the longitudinal axis L and which may be designed in particular as parts of the support element 1; In this case, the arrangement is such that the profile elements 31, 32, 33 of the assembly 3 are arranged between the two side walls 11, in particular such that between the profile elements 31, 32, 33 on the one hand and the adjacent side walls 11 on the other hand distances are formed which are smaller than 2 mm.

Die Seitenwände 11 erstrecken sich nach oben hin vorzugsweise so hoch, wie die angrenzenden Profilelemente 31, 32, 33. Die Seitenwände 11 können dementsprechend entlang des zweiten Längsbereichs L2 höher ausgebildet sein als entlang des ersten und des dritten Längsbereich L1, L3. Auch eignen sich die Seitenwände 11 dazu, einen Bauraum für das Betriebsgerät seitlich zu begrenzen.The side walls 11 preferably extend upwards as high as the adjacent profile elements 31, 32, 33. The side walls 11 can accordingly be made higher along the second longitudinal region L2 than along the first and third longitudinal regions L1 , L3. Also, the side walls 11 are to limit a space for the operating device side.

Zur Demontage der Baueinheit 3 kann daher vorgesehen sein, dass die Baueinheit 3 - nach Lösen der Schraubverbindung mit dem Trägerelement 1 - zunächst soweit nach oben gehoben wird, bis die Profilelemente 31, 32, 33 aus dem Höhenbereich der Seitenwände 11 freikommen und anschließend zur Seite wegbewegt wird.For disassembly of the assembly 3 can therefore be provided that the assembly 3 - after loosening the screw with the support element 1 - is first raised so far up until the profile elements 31, 32, 33 free from the height range of the side walls 11 and then to the side is moved away.

Der in Fig. 3 gezeigte Querschnitt ist auf Höhe des zweiten Profilelements 32 - bei Blick in Richtung auf den ersten Längsendbereich der Baueinheit 3 - gelegt; daher ist die Beschreibung im Folgenden auf dieses zweite Profilelement 32 gerichtet, gilt jedoch analog für das erste Profilelement 31 und gegebenenfalls für jedes weitere Profilelement der Baueinheit 3 entsprechend. Daher wird vereinfachend im Folgenden der Ausdruck "das Profilelement 32" so verwendet, dass er sich - soweit nicht ausdrücklich anders angegeben - auf jedes der Profilelemente 31, 32, 33 der Baueinheit 3 beziehen soll.The in Fig. 3 shown cross section is at the height of the second profile element 32 - when looking in the direction of the first longitudinal end of the assembly 3 - laid; Therefore, the description below is directed to this second profile element 32, but applies analogously to the first profile element 31 and optionally for each further profile element of the assembly 3 accordingly. Therefore, in the following, the expression "the profile element 32" will be used in the following in such a way that, unless expressly stated otherwise, it should refer to each of the profile elements 31, 32, 33 of the unit 3.

Bei dem Profilelement 32 handelt es sich beispielsweise um ein Strangpressprofil. Das Profilelement 32 kann aus Aluminium bestehen.The profile element 32 is, for example, an extruded profile. The profile element 32 may be made of aluminum.

Im Wesentlichen weist das Profilelement 32 im Querschnitt normal zu der Längsachse L betrachtet eine U-Form auf, so dass durch diese U-Form ein Kanal K gebildet ist. In diesem Kanal K ist der entsprechend zugehörige, hier also der zweite Abschnitt 22 der Lichtquelle 2 gehalten angeordnet. Insbesondere kann am Boden des Kanals K die betreffende, hier also die zweite Platine 82 angeordnet sein.In essence, the profile element 32 in the cross section normal to the longitudinal axis L considered a U-shape, so that a channel K is formed by this U-shape. In this channel K is the corresponding associated, here held the second portion 22 of the light source 2 held. In particular, at the bottom of the channel K, the relevant, in this case the second board 82 may be arranged.

Das erste Profilelement 31 ist vorteilhaft über ein Verbindungselement 4 mit dem zweiten Profilelement 32 verbunden. Insbesondere ist die Gestaltung derart, dass das erste Profilelement 31 lediglich über das Verbindungselement 4 mechanisch fest mit dem zweiten Profilelement 32 verbunden ist. Das Verbindungselement 4 kann beispielsweise als Blechteil gestaltet sein. Das Verbindungselement 4 ist vorzugsweise mit einem schrägen Abschnitt gestaltet, so dass durch diesen schrägen Abschnitt der Höhenversatz Δh zwischen dem ersten Profilelement 31 und dem zweiten Profilelement 32 realisiert ist.The first profile element 31 is advantageously connected via a connecting element 4 with the second profile element 32. In particular, the design is such that the first profile element 31 is mechanically fixed to the second profile element 32 only via the connecting element 4. The connecting element 4 may be designed, for example, as a sheet metal part. The connecting element 4 is preferably designed with an oblique section, so that the height offset Δ h between the first profile element 31 and the second profile element 32 is realized by this oblique section.

Das Verbindungselement 4 weist vorzugsweise eine Ausnehmung 41 auf, wobei das bzw. das erste Abhänge-Element 5 die Ausnehmung 41 durchsetzend angeordnet ist. Die Ausnehmung 41 ist vorzugsweise U-förmig geformt, insbesondere in einer horizontalen Ebene U-förmig geformt. Auf diese Weise lässt sich zur Demontage der Baueinheit 3 Letztere - nach Lösen der Schraubverbindung und Anheben über die Seitenwände 11 - einfach zu einer Seite hin fortbewegen, so dass das Abhänge-Element 5 aus der Ausnehmung 41 herausgelangt.The connecting element 4 preferably has a recess 41, wherein the or the first suspension element 5, the recess 41 is arranged to pass through.
