Description

Die vorliegende Erfindung betrifft eine Leuchte, welche ein längliches Trägerelement aufweist, an dem mehrere Leuchtmodule lösbar befestigbar sind.The present invention relates to a luminaire, which has an elongated support element, on which a plurality of lighting modules are releasably fastened.

Der Gedanke, Leuchtmodule auswechselbar an einem Trägerelement anzuordnen, ist insbesondere aus sogenannten Lichtbandsystemen bekannt. Es handelt sich hierbei um Beleuchtungssysteme, welche ein längliches Trägerelement, beispielsweise eine nach unten geöffnete U-förmige Tragschiene aufweisen, in oder an der Leitungen zur elektrischen Stromversorgung sowie gegebenenfalls auch zur Signalübertragung verlaufen. Je nach Ausgestaltung des Systems können dann Leuchtmodule an bestimmten, vorgegebenen Positionen oder frei an einer beliebigen Stelle der Tragschiene angeordnet werden. Hierbei weist jedes Leuchtmodul spezielle Kontaktierungselemente - zum Beispiel in Form so genannter Drehknebel - auf, welche einerseits eine mechanische Befestigung an der Tragschiene bewirken und andererseits auch eine Kontaktierung der Leitungen sicherstellen. Ferner weisen die Leuchtmodule in der Regel jeweils ein eigenes Betriebsgerät auf, welches die Netzversorgungsspannung, die über die entlang der Tragschiene verlaufenden Stromleitungen zur Verfügung gestellt wird, in eine geeignete Betriebsspannung zum Betrieb der Lichtquellen des Leuchtmoduls umsetzt.The idea of interchangeably arranging lighting modules on a carrier element is known in particular from so-called continuous line lighting systems. These are lighting systems which have an elongate support element, for example a downwardly open U-shaped mounting rail, in or on the lines for the electrical power supply and possibly also for signal transmission. Depending on the design of the system then lighting modules can be arranged at certain predetermined positions or freely at any point of the support rail. In this case, each light module special contacting elements - for example in the form of so-called rotary knob - on which on the one hand cause a mechanical attachment to the mounting rail and on the other hand ensure a contacting of the lines. Furthermore, the lighting modules generally each have their own operating device which converts the mains supply voltage, which is made available via the current lines running along the mounting rail, into a suitable operating voltage for operating the light sources of the lighting module.

Beispielsweise zeigt die US 2012/127702A1 eine Beleuchtungsanordnung mit einem länglichen Trägerelement an dem mehrere LED Module befestigt werden können. Ebenfalls an dem Trägerelement ist ein Konverter montiert, der elektrisch mit den LED Modulen verbunden ist. Ferner zeigt die US 2012/113634 A1 eine Leuchte gemäß dem Oberbegriff des Anspruchs 1.For example, the shows US 2012 / 127702A1 a lighting arrangement with an elongated support member to which a plurality of LED modules can be attached. Also mounted on the support member is a converter which is electrically connected to the LED modules. Furthermore, the shows US 2012/113634 A1 a luminaire according to the preamble of claim 1.

Ein lösbares Anordnen einzelner Module, welche jeweils Lichtquellen beinhalten, wäre auch bei Einzelleuchten sinnvoll, insbesondere dann, wenn es sich bei den zum Einsatz kommenden Lichtquellen um LEDs handelt. Im Vergleich zu klassischen Lichtquellen wie beispielsweise Glühbirnen oder Leuchtstofflampen ist das Auswechseln defekter LEDs oder defekter LED-Platinen in der Regel für den Endverbraucher nur schwer durchzuführen, so dass im Falle eines entsprechenden Defekts entweder die Leuchte ausgetauscht bzw. an den Hersteller geschickt werden muss oder Reparaturarbeiten durch einen geschulten Elektriker durchgeführt werden müssen. Dies liegt daran, dass aus sicherheitstechnischen Gründen in der Regel LED-Platinen derart in Leuchten verbaut werden, dass sie nicht ohne Weiteres zugänglich sind. Ein Grund hierfür ist, dass auf diese Weise die Gefahr von elektrischen Schlägen ausgeschlossen oder zumindest reduziert wird. Ferner kann ein versehentliches Berühren einer LED-Platine zu so genannten ESD-Schäden, also Schäden führen, die auf eine ungewünschte elektrische Entladung zurückzuführen sind. Dies führt dazu, dass LED-Lichtquellen in Leuchten in der Regel in spezieller abgeschirmter bzw. abgekapselter Weise angeordnet sind und ein Zugang zu den Platinen oftmals nur durch Zerstören bestimmter Komponenten, die einen entsprechenden Schutz darstellen, erreicht wird.A detachable arrangement of individual modules, which each contain light sources, would also be useful for individual luminaires, in particular if the light sources used are LEDs. Compared to conventional light sources such as light bulbs or fluorescent lamps, replacing defective LEDs or defective LED boards is usually difficult for the end user to perform, so that in case of a corresponding Defect either the lamp replaced or sent to the manufacturer or repair work must be performed by a trained electrician. This is because, for safety reasons, LED boards are generally installed in luminaires in such a way that they are not easily accessible. One reason for this is that in this way the risk of electric shock is eliminated or at least reduced. Furthermore, accidental touching of an LED board can lead to so-called ESD damage, that is, damage due to an unwanted electrical discharge. As a result, LED light sources in luminaires are usually arranged in a special shielded or encapsulated manner, and access to the circuit boards is often achieved only by destroying certain components that provide appropriate protection.

Es gibt Ansatzpunkte, die oben genannte Problematik dadurch zu umgehen, dass die LEDs in speziellen abgekapselten Modulen bereitgestellt werden, die lösbar an der Leuchte befestigt und mit entsprechenden Mitteln zur Stromversorgung elektrisch gekoppelt sind. Bei einem Defekt der LEDs wird dann nicht die entsprechende Platine individuell sondern das gesamte Modul ausgewechselt, was in der Regel auch durch den Endverbraucher verhältnismäßig einfach durchgeführt werden kann.There are starting points to circumvent the above-mentioned problem by providing the LEDs in special encapsulated modules which are releasably attached to the luminaire and electrically coupled to corresponding power supply means. In the event of a defect in the LEDs, it is then not the individual board that is replaced individually but the entire module, which as a rule can also be carried out relatively easily by the end user.

Der vorliegenden Erfindung liegt die Aufgabenstellung zugrunde, für eine Leuchte der vorbeschriebenen Art mit auswechselbaren Leuchtmodulen deren Aufbau zu vereinfachen. Insbesondere soll ein Zusammenbau der Leuchte im Hinblick auf die Mittel zur Stromversorgung der Leuchtmodule erleichtert werden.The present invention is based on the object to simplify the structure of a lamp of the type described above with interchangeable lighting modules. In particular, an assembly of the lamp is to be facilitated in terms of the means for powering the lighting modules.

Die Aufgabe wird durch eine Leuchte, welche die Merkmale des Anspruchs 1 aufweist, gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.The object is achieved by a luminaire having the features of claim 1. Advantageous developments of the invention are the subject of the dependent claims.

Die erfindungsgemäße Leuchte weist wie oben beschrieben ein längliches Trägerelement auf, an dem mehrere Leuchtmodule lösbar befestigbar sind. Ferner sind Mittel zur Stromversorgung der Leuchtmodule vorgesehen, wobei diese Mittel ein Betriebsgerät sowie mit dem Betriebsgerät verbundene Kontaktierungsmittel umfassen, an welche die Leuchtmodule elektrisch anschließbar sind. Das Betriebsgerät und die Kontaktierungsmittel sind dabei erfindungsgemäß an einem Geräteträger angeordnet, der vorzugsweise als vormontierte Baueinheit lösbar an dem Trägerelement der Leuchte befestigbar ist, wobei der Geräteträger an der den Leuchtmodulen abgewandten Seite des Trägerelements angeordnet ist und die Kontaktierungsmittel in dem Trägerelement ausgebildete Ausnehmungen durchgreifen.The luminaire according to the invention has, as described above, an elongate carrier element to which a plurality of lighting modules can be detachably fastened. Furthermore, means for supplying power to the lighting modules are provided, wherein these means comprise an operating device and contacting means connected to the operating device, to which the lighting modules are electrically connectable. The operating device and the contacting means are arranged according to the invention on a device carrier, which is preferably fastened as a preassembled unit detachably on the support element of the lamp, wherein the equipment carrier is disposed on the side facing away from the light modules of the support member and pass through the contacting means formed in the support member recesses.

Durch die erfindungsgemäße Lösung wird die Herstellung der Leuchte beziehungsweise deren Zusammenbau deutlich vereinfacht. Da alle wesentlichen Komponenten zur elektrischen Stromversorgung der auswechselbaren Leuchtmodule an dem Geräteträger angeordnet sind, kann dieser zunächst in einfacher Weise mit den entsprechenden Komponenten bestückt werden. Anschließend ist lediglich das Anordnen des Geräteträgers an dem Trägerelement der Leuchte erforderlich. Ein aufwendiges Verlegen einzelner Kabel zur Bereitstellung der individuellen Stromversorgung für die einzelnen Leuchtmodule entfällt hingegen, so dass die Leuchte insgesamt gesehen einen sehr übersichtlichen Aufbau aufweist. Wartungsbeziehungsweise Reparaturarbeiten, welche die Mittel zur Stromversorgung der Leuchtmodule betreffen, werden hierdurch ebenfalls erleichtert.The solution according to the invention significantly simplifies the manufacture of the luminaire or its assembly. Since all essential components for the electrical power supply of the exchangeable lighting modules are arranged on the equipment carrier, it can initially be fitted in a simple manner with the corresponding components. Subsequently, only the arrangement of the device carrier on the support element of the lamp is required. A complex laying of individual cables to provide the individual power supply for the individual lighting modules, however, eliminated, so that the light overall seen a very clear structure. Maintenance or repair work, which affect the means for powering the lighting modules are also facilitated.

Die Leuchtmodule werden also von der Unterseite beziehungsweise der Lichtabstrahlseite her an dem Trägerelement befestigt, während hingegen der Geräteträger von der gegenüberliegenden Seite her an dem Trägerelement angeordnet und dort vorzugsweise mit diesem verschnappt beziehungsweise verrastet wird. Auch diese Maßnahme trägt zur Verbesserung eventueller Wartungsarbeiten durch den Endverbraucher bei, da beim Auswechseln einzelner defekter Leuchtmodule von der Lichtabstrahlseite her mit Ausnahme der Kontaktierungsmittel alle weiteren Mittel zur Stromversorgung geschützt sind und nicht die Gefahr besteht, dass diese unbeabsichtigt berührt werden.The lighting modules are thus fastened to the carrier element from the lower side or the light emission side, while the device carrier is arranged on the carrier element from the opposite side and is preferably snapped or latched therewith. This measure also contributes to the improvement of any maintenance work by the end user, since when replacing individual defective lighting modules from the light emission side with the exception of the contacting all other means of power supply are protected and there is no risk that they are inadvertently touched.

Die Kontaktierungsmittel sind vorzugsweise nicht unmittelbar an dem Geräteträger, der selbst durch ein entsprechend geformtes Blechteil gebildet wird, angeordnet, sondern stattdessen an sogenannten Verbindungsplatinen. Diese sind wiederum lösbar an dem Geräteträger befestigt und weisen einerseits die Kontaktierungsmittel sowie andererseits Mittel zur elektrischen Verbindung mit dem Betriebsgerät der Leuchte auf. Bei diesen Mitteln zur elektrischen Verbindung kann es sich um einen einfachen Stecker oder eine Klemme handeln, über den bzw. die dann mit Hilfe eines entsprechenden Kabels ein Anschluss an das Betriebsgerät erfolgt. Die Kontaktierungsmittel zur Herstellung der elektrischen Verbindung zu dem entsprechenden Leuchtmodul sind dann beispielsweise über auf der Verbindungsplatte ausgebildete Leiterbahnen mit dem Stecker bzw. der Klemme verbunden. Vorzugsweise sind dabei auf jeder der Verbindungsplatinen mehrere Kontaktierungsmittel, beispielsweise zwei Kontaktierungsmittel angeordnet. Bei diesen Kontaktierungsmitteln kann es sich beispielsweise um Stecker oder Buchsen eines elektrischen Steckersystems handeln, welche dann mit einem geeigneten, an dem Leuchtmodul befindlichen Gegenstück zusammenwirken. Besonders bevorzugt werden die Kontaktierungsmittel allerdings durch einfache Kontaktelemente, insbesondere durch Federkontakte gebildet. Diese gelangen bei Anordnung eines Leuchtmoduls an dem Trägerelement der Leuchte in entsprechenden Kontakt mit an dem Leuchtmodul befindlichen Kontakten und stellen die elektrische Versorgung des Leuchtmoduls sicher.The contacting means are preferably not arranged directly on the equipment carrier, which itself is formed by a correspondingly shaped sheet-metal part, but instead on so-called connection boards. These are in turn releasably attached to the device carrier and on the one hand on the contacting means and on the other hand means for electrical connection to the operating device of the lamp. These means for electrical connection may be a simple Actuate a connector or a terminal, via which or with the aid of a corresponding cable, a connection to the operating device. The contacting means for producing the electrical connection to the corresponding light-emitting module are then connected to the plug or the terminal, for example via conductor tracks formed on the connection plate. Preferably, a plurality of contacting means, for example two contacting means, are arranged on each of the connecting boards. These contacting means may be, for example, plugs or sockets of an electrical connector system, which then interact with a suitable, located on the light module counterpart. However, the contacting means are particularly preferably formed by simple contact elements, in particular by spring contacts. These arrive in the arrangement of a light module to the support element of the lamp in corresponding contact with located on the light module contacts and make the electrical supply of the light module safely.

Gemäß der oben beschriebenen bevorzugten Weiterbildung der Erfindung sind also wiederum mehrere der Verbindungsplatinen an dem länglichen Geräteträger angeordnet, wobei dann jede der Verbindungsplatinen über Kabel mit dem Betriebsgerät verbunden ist. Dabei kommt besonders bevorzugt ein entsprechend ausgestalteter Kabelbaum zum Einsatz, der einerseits mit dem Betriebsgerät und andererseits mit den verschiedenen Verbindungsplatinen gekoppelt ist. Die einzelnen Leitungen des Kabelbaums weisen dabei eine unterschiedliche Länge auf und sind insbesondere derart bemessen, dass sie mit ihrer Länge in etwa dem Abstand zwischen der Verbindungsplatine beziehungsweise dem Stecker / der Klemme der Verbindungsplatine und dem Betriebsgerät entsprechen. Das heißt, der Kabelbaum weist speziell hinsichtlich ihrer Länge auf die Position der zu versorgenden Platine ausgebildete Kabel auf, so dass eine äußerst übersichtliche Kabelführung gewährleistet ist. Diese kann ferner noch dadurch optimiert beziehungsweise verbessert werden, dass die Kabel bis zu der anzuschließenden Verbindungsplatine in einem Zwischenraum zwischen den Verbindungsplatinen und dem Geräteträger geführt werden. Letztendlich wird also durch die erfindungsgemäße Lösung ein sehr übersichtlicher modularer Aufbau für die Leuchte geschaffen, durch den Reparatur- oder Wartungsarbeiten deutlich vereinfacht werden. Auch gestattet es der erfindungsgemäße Aufbau, in einfacher Weise Leuchten unterschiedlicher Abmessungen und mit dementsprechend unterschiedlichen Anzahlen von auswechselbaren Leuchtmodulen zu Verfügung zu stellen.According to the preferred embodiment of the invention described above, in turn, several of the connection boards are arranged on the elongate device carrier, in which case each of the connection boards is connected via cables to the operating device. In this case, a suitably designed wiring harness is particularly preferably used, which is coupled on the one hand to the operating device and on the other hand to the various connection boards. The individual lines of the wiring harness have a different length and are particularly dimensioned such that they correspond with their length in about the distance between the connection board or the plug / terminal of the connection board and the operating device. That is, the harness has specifically with regard to their length to the position of the circuit board to be supplied cable, so that a very clear cable management is guaranteed. This can be further optimized or improved by the fact that the cables are led to the connection plate to be connected in a space between the connection boards and the equipment carrier. Ultimately, therefore, a very clear modular design for the lamp is created by the inventive solution, are significantly simplified by the repair or maintenance. Also allows the structure of the invention, in a simple way lights different Dimensions and with correspondingly different numbers of interchangeable lighting modules to provide.

Die Figuren 1 und 2 zeigen unterschiedliche Ansichten der allgemein mit dem Bezugszeichen 1 versehenen erfindungsgemäßen Leuchte. Die Leuchte 1 ist im dargestellten Ausführungsbeispiel als Pendelleuchte ausgebildet und kann in diesem Fall über wenigstens ein Aufhängeelement, im dargestellten Fall über mehrere Seile 2 an einem nicht dargestellten Trägerelement, beispielsweise an der Decke eines Raums befestigt werden. In leicht modifizierter Weise könnte die erfindungsgemäße Leuchte 1 allerdings auch als Deckenanbauleuchte genutzt werden.The Figures 1 and 2 show different views of the generally provided with the reference numeral 1 inventive lamp. The lamp 1 is formed in the illustrated embodiment as a pendant light and can be attached in this case via at least one suspension element, in the illustrated case over several cables 2 to a support element, not shown, for example, on the ceiling of a room. In a slightly modified way, however, the luminaire 1 according to the invention could also be used as a ceiling-mounted luminaire.

Wie in den Figuren erkennbar ist, ist die Leuchte 1 insgesamt länglich ausgeführt und erstreckt sich hierbei entlang einer Längsachse L. Die Form der Leuchte 1 wird hierbei in erster Linie durch ein Trägerelement 5 festgelegt, welches das zentrale Element der Leuchte 1 darstellt, an dem alle weiteren Komponenten angeordnet beziehungsweise befestigt sind. Ein wesentliches Merkmal dieses Trägerelements 5 ist, dass dieses an seiner Unterseite beziehungsweise seiner Lichtabstrahlseite einen später noch näher beschriebenen, im Querschnitt U-förmigen Aufnahmebereich bildet, in dem mehrere Leuchtmodule auswechselbar angeordnet werden können. Das Trägerelement 5 ist vorzugsweise durch ein Aluminiumprofil gebildet, welches an seinen beiden stirnseitigen Endbereichen durch Endkappen 15 abgeschlossen wird, die wiederum lösbar an dem Trägerelement 5 befestigt sind.As can be seen in the figures, the luminaire 1 is designed to be elongated overall and extends along a longitudinal axis L. The shape of the luminaire 1 is determined primarily by a carrier element 5, which represents the central element of the luminaire 1 on which all other components are arranged or attached. An essential feature of this carrier element 5 is that this forms on its underside or its Lichtabstrahlseite a later described in more detail, in cross section U-shaped receiving area in which a plurality of lighting modules can be arranged interchangeable. The support element 5 is preferably formed by an aluminum profile, which is closed at its two end-side end portions by end caps 15, which in turn are releasably secured to the support member 5.

Figur 6 zeigt den Endbereich des Trägerelements 5 von der Unterseite her, wobei nunmehr der Aufnahmebereich 6 für die auswechselbaren Leuchtmodule erkennbar ist. Dieser Aufnahmebereich wird durch eine Bodenfläche 7 sowie zwei zu beiden Seiten der Bodenfläche 7 verlaufende, nach unten gerichtete U-Schenkel 8 gebildet. Gemeinsam mit den bereits erwähnten Stirnelementen beziehungsweise Abschlusskappen 15 wird hierdurch der im Querschnitt U-förmige, insgesamt gesehene längliche topfförmige Aufnahmebereich 6 gebildet. In diesem werden dann mehrere Leuchtmodule - im dargestellten Ausführungsbeispiel 14 Leuchtmodule - angeordnet, wobei eines hiervon in Figur 5 in perspektivischer Ansicht gezeigt ist. FIG. 6 shows the end portion of the support member 5 from the underside ago, now the receiving area 6 for the replaceable lighting modules can be seen. This receiving area is formed by a bottom surface 7 and two downwardly directed U-legs 8 extending on both sides of the bottom surface 7. Together with the already mentioned end elements or end caps 15, the elongate cup-shaped receiving region 6, which is U-shaped overall, is thus formed. In this then several light modules - in the illustrated embodiment 14 light modules - arranged, one of them in FIG. 5 is shown in perspective view.

Das Leuchtmodul 20 ist also in etwa quaderförmig ausgebildet. Wie insbesondere den Schnittdarstellungen der Figuren 7 und 8 entnommen werden kann, besteht dabei das Leuchtmodul 20 aus einem topfartig ausgebildeten, aus zumindest teillichtdurchlässigem Material gebildeten sogenannten Linsenträger 21, der eine Bodenfläche 22, welche die Lichtabstrahlfläche des Leuchtmoduls 20 bildet, sowie vier Seitenwände 23, 24 aufweist. An den beiden kürzeren Seitenwänden 24 sind hierbei jeweils zwei Rastlaschen 25 ausgebildet, über welche ein Befestigen an dem Trägerelement 5 der Leuchte 1 erfolgt. Wie der Darstellung von Figur 6 entnommen werden kann, sind hierzu in der Bodenfläche 7 des Aufnahmebereichs 6 des Trägerelements 5 entsprechende Rastausnehmungen beziehungsweise Schlitze 9 ausgebildet, in welche die Rastlaschen 25 des Leuchtmoduls 20 rastend eingreifen.The lighting module 20 is thus formed approximately cuboid. As in particular the sectional views of FIGS. 7 and 8 can be removed, while the lighting module 20 consists of a cup-shaped, formed from at least teillichtdurchlässigem material so-called lens carrier 21 having a bottom surface 22, which forms the light emitting surface of the light module 20, and four side walls 23, 24. At the two shorter side walls 24 in each case two locking tabs 25 are formed, via which a fastening to the carrier element 5 of the lamp 1 takes place. Like the presentation of FIG. 6 can be removed, 5 corresponding recesses or slots 9 are formed for this purpose in the bottom surface 7 of the receiving portion 6 of the support member, in which engage the locking tabs 25 of the lighting module 20 latching.

Die Bodenfläche des Leuchtmoduls 20 wird durch die Rückseite einer Platine 30 mit mehreren darauf angeordneten, vorzugsweise matrixartig verteilten LEDs 31 (siehe Figur 7) gebildet. Diese LEDs 31 stellen die Lichtquellen des Leuchtmoduls 20 dar, wobei den LEDs 31 unterschiedliche optische Mittel zur Beeinflussung der Lichtabgabe zugeordnet sein können.The bottom surface of the light-emitting module 20 is arranged through the rear side of a circuit board 30 with a plurality of LEDs 31, preferably matrix-like, distributed among them (see FIG FIG. 7 ) educated. These LEDs 31 represent the light sources of the light module 20, wherein the LEDs 31 may be associated with different optical means for influencing the light output.

Wie in Figur 7 erkennbar ist, sind dabei bei dem dargestellten Ausführungsbeispiel im zentralen Bereich des Linsenträgers 21 Linsenkörper 26 ausgebildet, die jeweils einzelnen LEDs 31 zugeordnet sind. Das Licht der im Randbereich befindlichen LEDs 31a hingegen soll nicht mit Hilfe von Linsen gerichtet abgestrahlt werden, sondern einen eher diffus leuchtenden umlaufenden Rahmen hervorrufen. Dies wird durch einen speziellen Diffusorrahmen 35 erzielt, der in den Linsenträger 21 eingelegt wird und im Vergleich zu dem Linsenträger 21, der vorzugsweise aus einem klaren Material besteht, aus einem lichtstreuenden Material gebildet ist beziehungsweise lichtstreuende Partikel enthält. Anzumerken ist allerdings, dass selbstverständlich die Ausgestaltung der optischen Elemente der einzelnen Leuchtmodule 20 auch anderweitig gestaltet werden könnte, sofern eine andere Art der Lichtabstrahlung gewünscht ist. Die Ausgestaltung dieser optischen Elemente ist für den Kerngedanken der vorliegenden Erfindung nicht weiter relevant. Wesentlich ist jedoch, dass mehrere der Leuchtmodule 20 an dem Trägerelement 5 der Leuchte 1 befestigt werden, so dass sich von der Unterseite beziehungsweise der Lichtabstrahlseite der Leuchte 1 her ein Erscheinungsbild ergibt, wie es in Figur 4 dargestellt ist.As in FIG. 7 can be seen, 21 lens body 26 are formed in the illustrated embodiment in the central region of the lens carrier, which are each associated with individual LEDs 31. On the other hand, the light from the LEDs 31a located in the edge region should not be emitted with the aid of lenses, but should rather produce a rather diffuse surrounding frame. This is achieved by a special diffuser frame 35, which is inserted into the lens carrier 21 and, in comparison to the lens carrier 21, which preferably consists of a clear material, is formed from a light-scattering material or contains light-scattering particles. It should be noted, however, that of course the design of the optical elements of the individual lighting modules 20 could also be designed otherwise, if another type of light emission is desired. The design of these optical elements is not relevant to the gist of the present invention. It is essential, however, that a plurality of the lighting modules 20 are fastened to the carrier element 5 of the luminaire 1, so that an appearance results from the underside or the light emitting side of the luminaire 1, as shown in FIG FIG. 4 is shown.

Die die Rückseite des Leuchtmoduls 20 bildende LED-Platine 30 ist mit dem Linsenträger 21 verrastet. An den beiden Seitenwänden 23 sind hierfür entsprechende Rastelemente 27 ausgebildet, welche mit der Platine 30 derart zusammenwirken, dass diese in einfacher Weise von der Rückseite her auf den offenen Linsenträger 21 aufgelegt und dann herabgedrückt werden kann. Auf diese Weise wird eine stabile Baueinheit gebildet, durch welche wiederum die einzelnen LEDs 31 effizient vor äußeren Einflüssen geschützt sind.The rear side of the light module 20 forming LED board 30 is locked to the lens carrier 21. For this purpose, corresponding latching elements 27 are formed on the two side walls 23, which cooperate with the board 30 in such a way that they can be easily placed on the open lens carrier 21 from the rear side and then pressed down. In this way, a stable structural unit is formed, by which in turn the individual LEDs 31 are efficiently protected against external influences.

Die Stromversorgung der an dem Trägerelement 5 angeordneten Leuchtmodule 20 erfolgt mit Hilfe spezieller Kontaktierungsmittel, die im dargestellten Ausführungsbeispiel Federkontakte 41 umfassen, welche mit an der Rückseite der LED-Platine 30 angeordneten Kontaktfeldern 35 zusammenwirken. Die Federkontakte 41 sind hier jeweils an einem in Figur 7 erkennbaren Kontaktblock 40 angeordnet, der durch eine entsprechende Ausnehmung 10 in der Bodenfläche 7 des Aufnahmebereichs 6 des Trägerelements 5 ragt. Das heißt, diese Federkontakte 41 sind von dem Aufnahmebereich 6 des Trägerelements 5 her derart zugänglich, dass sie beim Einsetzen des Leuchtmoduls 20 in den Aufnahmebereich 6 in Anlage gegen die Kontaktfelder 35 des Leuchtmoduls 20 gelangen. Hierdurch wird die elektrische Verbindung zwischen den Federkontakten 41 und dem Leuchtmodul 20 sichergestellt, so dass dieses - wie nachfolgend noch näher beschrieben - mit den eigentlichen Mitteln zur Bereitstellung eines Betriebsstroms für die LEDs 31 verbunden wird.The power supply of the arranged on the support member 5 lighting modules 20 is carried out with the aid of special contacting means comprising spring contacts 41 in the illustrated embodiment, which cooperate with disposed on the back of the LED board 30 contact pads 35. The spring contacts 41 are here in each case at an in FIG. 7 recognizable contact block 40 which projects through a corresponding recess 10 in the bottom surface 7 of the receiving portion 6 of the support member 5. That is, these spring contacts 41 are accessible from the receiving region 6 of the support member 5 forth so that they arrive when inserting the light module 20 in the receiving area 6 in abutment against the contact pads 35 of the light module 20. As a result, the electrical connection between the spring contacts 41 and the lighting module 20 is ensured, so that this - as described in more detail below - is connected to the actual means for providing an operating current for the LEDs 31.

Wie der Darstellung von Figur 5 entnommen werden kann sind dabei eine Vielzahl von Kontaktfeldern 35 auf der Rückseite der LED-Platine 30 ausgebildet, wobei abhängig von der Betriebsart der Leuchte 1 nicht zwingend alle Kontaktfelder 35 genutzt werden müssen. Dies ist unter anderem davon abhängig, ob lediglich ein einfaches Ein- und Ausschalten der Module 20 vorgesehen ist oder ob diese eine individuelle Ansteuerbarkeit ermöglichen sollen. Im dargestellten Ausführungsbeispiel kommen lediglich zwei Federkontakte 41 zum Einsatz, so dass also die Module 20 ausschließlich mit einer geeigneten Versorgungsspannung bzw. einem Versorgungsstrom versorgt werden und dementsprechend alle Module einheitlich betrieben werden. Eine Kommunikation, die darüber hinaus beispielsweise auch das Rückmelden von Fehlerinformationen oder dergleichen ermöglichen würde, ist im dargestellten Ausführungsbeispiel nicht vorgesehen, wobei für diesen Fall dann gegebenenfalls mehrere der Kontaktfelder 35 genutzt werden.Like the presentation of FIG. 5 can be taken from a plurality of contact pads 35 are formed on the back of the LED board 30, wherein not necessarily all contact fields 35 must be used depending on the operating mode of the lamp 1. This depends inter alia on whether only a simple switching on and off of the modules 20 is provided or whether they should allow an individual controllability. In the illustrated embodiment, only two spring contacts 41 are used, so that therefore the modules 20 are supplied exclusively with a suitable supply voltage or a supply current and, accordingly, all modules are operated uniformly. A communication, which would also allow, for example, the feedback of error information or the like, is in illustrated embodiment, in which case optionally several of the contact fields 35 are then used for this case.

Eine weitere Besonderheit besteht dabei darin, dass - wie in Figur 5 erkennbar - zwei Reihen von Kontaktfeldern 35 vorgesehen sind, die bezüglich einer Längsachse 1 des Leuchtmoduls 20 um 180° verdreht zueinander angeordnet sind. Grund für diese Maßnahme ist, dass hierdurch die Möglichkeit besteht, das Leuchtmodul 20 wahlweise in unterschiedlichen Orientierungen, insbesondere in zwei um 180° verdrehten Orientierungen an dem Trägerelement 5 anzuordnen. Dies kann dann von Interesse sein, wenn die optischen Elemente des Leuchtmoduls 20 derart ausgebildet sind, dass sie eine asymmetrische Lichtabgabe verstärkt in eine Richtung hin bewirken. In diesem Fall kann möglicherweise vorgesehen sein, dass beispielsweise die an den jeweiligen Endbereichen des Trägerelements 5 angeordneten Leuchtmodule 20 verdreht zueinander ausgerichtet sind, was wiederum insgesamt gesehen eine symmetrische Lichtabgabe der Leuchte 1 bewirken würde. Durch das Anordnen zweier gleichartiger, allerdings um 180° verdreht zueinander angeordneter Kontaktfelder 35 kann in einfacher Weise ein entsprechendes wahlweises Anordnen der Leuchtmodule 20 ermöglicht werden, ohne dass diese noch anderweitig modifiziert werden müssten.Another special feature is that - as in FIG. 5 recognizable - two rows of contact pads 35 are provided, which are arranged with respect to a longitudinal axis 1 of the light-emitting module 20 rotated by 180 ° to each other. The reason for this measure is that this makes it possible to arrange the light module 20 optionally in different orientations, in particular in two orientations rotated by 180 ° on the carrier element 5. This may be of interest if the optical elements of the light-emitting module 20 are designed in such a way that they cause an asymmetrical light emission amplified in one direction. In this case, it may possibly be provided that, for example, the lighting modules 20 arranged at the respective end regions of the carrier element 5 are aligned with respect to one another in a twisted manner, which in turn would cause a symmetrical light emission of the luminaire 1 as a whole. By arranging two similar, but rotated by 180 ° to each other arranged contact fields 35, a corresponding optional arrangement of the lighting modules 20 can be made possible in a simple manner, without these would have to be otherwise modified.

Anzumerken ist, dass anstelle der dargestellten Federkontakte und damit zusammenwirkenden Kontaktfeldern auch Steckersysteme zum Anschließen der Leuchtmodule verwendet werden könnten.It should be noted that instead of the illustrated spring contacts and cooperating contact fields and connector systems could be used to connect the lighting modules.

Die Figuren 7 und 8 zeigen wie bereits erwähnt eine Schnittdarstellung der Leuchte 1, wobei zunächst in Figur 7 das Leuchtmodul 20 beabstandet von dem Trägerelement 5 angeordnet und in Figur 8 an dem Trägerelement 5 befestigt ist. Der Darstellung der Figuren 7 und 8 kann darüber hinaus auch die Form des Trägerelements 5 entnommen werden, wobei erkennbar ist, dass dieses oberhalb des U-förmigen Aufnahmebereichs 6 zwei in Längsrichtung verlaufende Seitenwände 12 aufweist, welche einen schmaleren, nach oben hin gerichteten und wiederum U-förmigen zweiten Aufnahmebereich 13 bilden.The FIGS. 7 and 8 show as already mentioned a sectional view of the lamp 1, wherein initially in FIG. 7 the light module 20 spaced from the support member 5 and arranged in FIG. 8 is attached to the support element 5. The representation of the FIGS. 7 and 8 In addition, the shape of the carrier element 5 can be taken, wherein it can be seen that this above the U-shaped receiving portion 6 has two longitudinally extending side walls 12, which form a narrower, upwardly directed and turn U-shaped second receiving portion 13 ,

Diese Seitenwände 12 sind auch in den Darstellungen der Figuren 1 bis 3 gut erkennbar, wobei ferner ersichtlich ist, dass die Wände 12 nicht über die gesamte Länge der Leuchte 1 hinweg die gleiche Höhe aufweisen. Insbesondere ist - in Längsrichtung gesehen - im mittleren Bereich der Leuchte 1 ein leicht erhöhter Aufnahmeraum 13a gebildet, der der Aufnahme des Betriebsgeräts 100 der Leuchte 1 dient, über welches die externe Versorgungsspannung in eine geeignete Betriebsspannung bzw. einen Betriebsstrom für die Leuchtmodule 20 umgesetzt wird. Ferner ist in diesem mittleren Aufnahmeraum 13a oberhalb des Betriebsgeräts 100 noch eine Leuchteinheit 60 zum Erzeugen einer Indirektbeleuchtung vorgesehen. Zu beiden Seiten dieses erhöhten mittleren Bereichs 13a sind etwas niedrigere Aufnahmebereiche 13b ausgebildet, die ebenfalls der Aufnahme von weiteren Leuchteinheiten zur Erzeugung einer Indirektbeleuchtung dienen können, welche im vorliegenden Fall allerdings nicht näher erläutert werden sollen.These side walls 12 are also in the representations of FIGS. 1 to 3 clearly recognizable, it being further apparent that the walls 12 do not cover the whole Length of the lamp 1 across the same height. In particular, viewed in the longitudinal direction, a slightly raised receiving space 13a is formed in the central region of the luminaire 1, which serves to receive the operating device 100 of the luminaire 1, via which the external supply voltage is converted into a suitable operating voltage or operating current for the luminous modules 20 , Furthermore, in this middle receiving space 13a above the operating device 100, a lighting unit 60 is still provided for generating an indirect lighting. On both sides of this raised central region 13a slightly lower receiving areas 13b are formed, which can also serve to accommodate further lighting units for generating an indirect lighting, which will not be explained in detail in the present case.

Die vorliegende Erfindung befasst sich stattdessen mit speziellen Maßnahmen, mit deren Hilfe die elektrische Verbindung zwischen dem Betriebsgerät 100 und den Federkontakten 41, über welche letztendlich die Kontaktierung der Leuchtmodule 20 erfolgt, sichergestellt wird.Instead, the present invention deals with special measures by means of which the electrical connection between the operating device 100 and the spring contacts 41, via which the contacting of the lighting modules 20 ultimately takes place, is ensured.

Hierzu sind in den Figuren 9 und 10 Darstellungen eines so genannten Geräteträgers 50 gezeigt, der durch ein längliches Blechteil gebildet wird und als zentrales Halteelement für die Komponenten zur Stromversorgung der Leuchtmodule 20 dient. Der Geräteträger 50 dient also insbesondere der Halterung der Kontaktblöcke 40 mit den Federkontakten 41, wobei diese allerdings nicht unmittelbar an dem Geräteträger 50 angeordnet sondern stattdessen auf sogenannten Verbindungsplatinen 45 montiert sind. Diese Verbindungsplatinen 45, wobei eine hiervon in Figur 9 dargestellt ist, weisen dabei jeweils zwei Kontaktblöcke 40 mit Federkontakten 41 auf, sind also letztendlich zur Kontaktierung durch zwei Leuchtmodule 20 ausgebildet.These are in the FIGS. 9 and 10 Representations of a so-called device carrier 50 shown, which is formed by an elongated sheet metal part and serves as a central holding element for the components for powering the lighting modules 20. The device carrier 50 thus serves in particular to hold the contact blocks 40 with the spring contacts 41, although these are not arranged directly on the device carrier 50 but instead are mounted on so-called connection boards 45. These connection boards 45, one of them in FIG. 9 is shown, in each case have two contact blocks 40 with spring contacts 41, so are ultimately designed for contacting by two lighting modules 20.

Das Anordnen der Verbindungsplatinen 45 an dem Geräteträger 50 erfolgt wiederum vorzugsweise werkzeuglos, was dadurch erzielt wird, dass die Platinen 45 an ihren Längsseiten längliche Überstände 46 aufweisen. Diese sind dazu vorgesehen, mit dem Geräteträger 50 im Sinne einer Bajonettverriegelung verbunden zu werden. Der im Querschnitt C-förmig gebogene Geräteträger 50 weist hierzu also zwei längliche Seitenwände 51 auf, an denen jeweils Ausnehmungen 52 ausgebildet sind, welche in Hinterschneidungen 53 münden. Die Verbindungsplatine 45 wird dann von der Oberseite her (gemäß der Darstellung in Figur 9) aufgelegt, derart, dass die Überstände 46 in die Ausnehmungen 52 eingreifen. Anschließend wird die Platine 45 in Pfeilrichtung gegenüber dem Geräteträger 50 verschoben, sodass die Überstände 46 in die Hinterschneidungen 53 eingreifen. Hierdurch wird die Platine 45 sicher an dem Geräteträger 50 gelagert, ohne dass hierfür ein Werkzeug oder zusätzliche Verbindungsmittel erforderlich wären. An dem Geräteträger 50 werden auf diese Weise dann ein Mehrzahl entsprechender Verbindungsplatinen 45 angeordnet, wobei im vorliegenden Fall also halb so viel Platinen 45 erforderlich sind, wie Leuchtmodule 20 an dem Trägerelement 5der Leuchte 1 befestigt werden sollen.The arrangement of the connection boards 45 on the equipment carrier 50 is again preferably done without tools, which is achieved in that the boards 45 have elongated projections 46 on their longitudinal sides. These are intended to be connected to the device carrier 50 in the sense of a bayonet lock. The cross-sectionally C-shaped device carrier 50 has for this purpose therefore two elongated side walls 51, on each of which recesses 52 are formed, which open into undercuts 53. The connection board 45 is then removed from the Top side (as shown in FIG. 9 ), such that the projections 46 engage in the recesses 52. Subsequently, the board 45 is moved in the direction of the arrow relative to the device carrier 50, so that the projections 46 engage in the undercuts 53. As a result, the board 45 is securely stored on the device carrier 50, without the need for a tool or additional connecting means would be required. At the equipment rack 50, a plurality of corresponding connection boards 45 are arranged in this way, so in the present case, half as many boards 45 are required as lighting modules 20 are to be attached to the support member 5 of the lamp 1.

Auf jeder Verbindungsplatine 45 ist dabei darüber hinaus auch ein Stecker 44 - auch die Verwendung einer Klemme wäre denkbar - angeordnet, der über nicht näher dargestellte Leiterbahnen mit den Kontaktblöcken 40 verbunden ist. Der Stecker 44 befindet sich an der den Kontaktblöcken 40 gegenüberliegenden Seite der Platine 45 und wird mit dem Betriebsgerät 100 über Kabel verbunden. Auf diesem Wege wird also die elektrische Verbindung zwischen Betriebsgerät 100 und Kontaktblöcken 40 sichergestellt.On each interconnect board 45 is also a plug 44 - the use of a terminal would be conceivable - arranged, which is connected via non-illustrated interconnects with the contact blocks 40. The plug 44 is located on the opposite side of the contact blocks 40 of the board 45 and is connected to the operating device 100 via cables. In this way, therefore, the electrical connection between the operating device 100 and contact blocks 40 is ensured.

Figur 11 zeigt einen gesamten Geräteträger 50 mit den an der Unterseite angeordneten Verbindungsplatinen 45 sowie dem an der gegenüberliegenden Seite angeordneten Betriebsgerät 100. Auf der Seite des Betriebsgeräts 100 ist darüber hinaus auch noch eine Klemme 101 angeordnet, über welche die Verbindung mit den externen Stromversorgungsleitungen erfolgt. FIG. 11 shows an entire device carrier 50 with the arranged on the bottom connecting plates 45 and arranged on the opposite side operating device 100. On the side of the operating device 100 is also a terminal 101 is also arranged, via which the connection to the external power supply lines.

Wie bereits erwähnt erfolgt die Verbindung zwischen dem Betriebsgerät 100 und den Verbindungsplatinen 45 über Kabel, wobei hierzu vorzugsweise ein Kabelbaum zum Einsatz kommt, der Leitungen aufweist, die einerseits mit dem Betriebsgerät 100 und andererseits mit den Verbindungsplatinen 45, genau genommen mit den Steckern 44 der Verbindungsplatinen 45 verbunden sind. Die Kabel des - nicht dargestellten - Kabelbaums sind dabei hinsichtlich ihrer Länge auf den Abstand zwischen dem Betriebsgerät 100 und den Verbindungsplatinen 45 abgestimmt, so dass keine lose verlaufenden Kabelschlaufen verbleiben. Stattdessen werden die Kabel vorzugweise in dem Zwischenbereich zwischen Bodenfläche 55 des Geräteträgers 50 und Verbindungsplatine 45 geführt, so dass letztendlich eine aufgeräumte Baueinheit erhalten wird, wie sie in Figur 11 dargestellt ist. Diese enthält alle wesentlichen Komponenten zur Stromversorgung der Leuchtmodule 20 und kann dann in einfacher Weise an dem Trägerelement 5 der Leuchte 1 befestigt werden.As already mentioned, the connection between the operating device 100 and the connection boards 45 is made by cable, for which purpose a wiring harness is preferably used which has lines which are connected on the one hand to the operating device 100 and on the other hand to the connection boards 45, to be precise with the plugs 44 Connection boards 45 are connected. The cables of the - not shown - harness are tuned in terms of their length to the distance between the operating device 100 and the connection boards 45, so that no loosely extending cable loops remain. Instead, the cables are preferably guided in the intermediate region between the bottom surface 55 of the device carrier 50 and connection board 45, so that ultimately a tidy structural unit is received, as in FIG. 11 is shown. This contains all the essential components for the power supply of the lighting modules 20 and can then be attached in a simple manner to the support element 5 of the lamp 1.

Das Befestigen des Geräteträgers 50 erfolgt dabei wiederum vorzugsweise werkzeuglos, wobei hierfür insbesondere ein Verrasten vorgesehen ist. Dies wird dadurch erzielt, dass an den Seitenwänden 51 des Geräteträgers 50 ausgewölbte Noppen 56 ausgebildet sind, wie sie insbesondere in Figur 10 gut erkennbar sind. Mit Hilfe dieser Noppen 56 wird dann der Geräteträger 50 mit dem Trägerelement 5 der Leuchte 1 verrastet. Dies erfolgt dadurch, dass der Geräteträger 50 von der Oberseite her in den offenen oberen Aufnahmebereich 13 des Trägerelements 5 eingesetzt und zur Unterseite hin gedrückt wird, bis die ausgewölbten Noppen 56 entsprechend nach innen ragende Vorsprünge 15 des Aluminiumprofils, welches das Trägerelement 5 bildet, hintergreifen. Durch eine Führungsnase 57, welche an einem stirnseitigen Ende des Geräteträgers 50 ausgebildet ist und in eine Ausnehmung in dem Geräteträger 5 eingreift, wird dabei sichergestellt, dass der Geräteträger 50 richtig positioniert und orientiert in das Trägerelement 5 eingesetzt wird.The attachment of the device carrier 50 is again preferably without tools, in which case in particular a locking is provided. This is achieved by the fact that on the side walls 51 of the device carrier 50 bulged nubs 56 are formed, as in particular in FIG. 10 are clearly recognizable. With the help of these knobs 56 of the device carrier 50 is then locked to the support member 5 of the lamp 1. This is done by the device carrier 50 is inserted from the top into the open upper receiving portion 13 of the support member 5 and pressed towards the bottom until the bulged nubs 56 engage corresponding inwardly projecting projections 15 of the aluminum profile, which forms the support member 5, behind , By a guide lug 57 which is formed at an end face of the device carrier 50 and engages in a recess in the device carrier 5, it is ensured that the device carrier 50 is positioned correctly and oriented in the carrier element 5 is used.

Die Verrastung kann sehr gut der vergrößerten Darstellung gemäß Figur 12 entnommen werden, welche die Anordnung des Geräteträgers 50 in dem Trägerelement 5 zeigt. Erkennbar ist hierbei auch der Zwischenraum zwischen der Bodenfläche 55 des Geräteträgers und der Verbindungsplatine 45, der zum Führen der - nicht gezeigten -Leitungen des Kabelbaums genutzt werden kann und in dem sich auch die Stecker bzw. Anschlüsse 44 befinden. Ferner ist erkennbar, in welcher Weise die Kontaktblöcke 40 mit den Federkontakten 41 die Ausnehmungen 10 in der Bodenfläche 6 des unteren Aufnahmebereichs durchgreifen, derart, dass sie für die Kontaktierungsfelder 35 der Leuchtmodule 20 zugänglich sind.The locking can very well according to the enlarged view FIG. 12 which shows the arrangement of the device carrier 50 in the carrier element 5. Visible here is also the gap between the bottom surface 55 of the device carrier and the connection board 45, which can be used to guide the - not shown -Leitungen the wiring harness and in which the plug or terminals 44 are located. It can also be seen in which way the contact blocks 40 with the spring contacts 41 pass through the recesses 10 in the bottom surface 6 of the lower receiving region, such that they are accessible to the contacting fields 35 of the lighting modules 20.

Letztendlich wird also durch die spezielle Ausgestaltung des erfindungsgemäßen Geräteträgers eine sehr modulare Bauweise für die Leuchte insgesamt erzielt. Die einzelnen Komponenten können als vorgefertigte Baueinheiten sehr einfach und schnell an dem Trägerelement der Leuchte montiert und insbesondere auch werkzeuglos befestigt werden, so dass einerseits der Zusammenbau der Leuchte erleichtert wird, insbesondere jedoch auch Wartungsarbeiten sehr einfach durchgeführt werden können.Ultimately, therefore, a very modular design for the lamp is achieved in total by the special design of the device carrier according to the invention. The individual components can be mounted as prefabricated units very quickly and easily to the support element of the lamp and in particular also attached without tools, so that on the one hand, the assembly of the lamp is facilitated, but in particular also maintenance can be performed very easily.
