Description

Die vorliegende Erfindung betrifft eine Leuchte mit einer Tragschiene und Platinen, auf denen LEDs (Light Emitting Diodes, worunter hierin jede Art von Halbleiterlichtquelle einschließlich organischer LED verstanden wird) vorgesehen sind.The present invention relates to a luminaire with a mounting rail and boards, on which LEDs (Light Emitting Diodes, which is understood here any type of semiconductor light source including organic LED) are provided.

Tragschienenleuchten sind insbesondere zur Ausbildung von Lichtbändern sehr geläufig. Während früher insbesondere Leuchtstofflampen für derartige Tragschienenleuchten üblich waren, werden heutzutage überwiegend LEDs eingesetzt. Die LEDs sind auf Platinen angebracht, die in den Tragschienen gehalten werden. Eine solche Leuchte ist beispielsweise in der DE 10 2012 220 977 A1 beschrieben. Die Platinen werden durch Fixierungselemente an einem Grundkörper gehalten, wobei jedes Fixierungselement in eine Vertiefung der Platine eingesteckt ist und ein an der Außenseite des Fixierungselements angeordnetes hakenförmiges Verbindungsstück in ein Gegenstück des Grundkörpers eingreift.Guideway lights are very common especially for the formation of light bands. Whereas in the past fluorescent lamps in particular were customary for such mounting rail lamps, LEDs are predominantly used today. The LEDs are mounted on circuit boards, which are held in the mounting rails. Such a lamp is for example in the DE 10 2012 220 977 A1 described. The circuit boards are held by fixing elements on a base body, wherein each fixing element is inserted into a recess of the board and a arranged on the outside of the fixing element hook-shaped connecting piece engages in a counterpart of the base body.

Eine alternative Art der Befestigung von LED-Platinen in einer Leuchte ist in der DE 20 2015 102 516 U1 beschrieben. Darin ist ein Federelement vorgesehen, welches in eine Nut eines Grundkörpers eingesteckt wird und sich darin durch Verspreizen festklemmt. Ein Haltearm, der einstückig mit dem Federelement verbunden ist, drückt auf den Rand einer benachbarten LED-Platine, um diese an dem Grundkörper zu halten.An alternative way of mounting LED boards in a luminaire is in the DE 20 2015 102 516 U1 described. Therein, a spring element is provided, which is inserted into a groove of a base body and clamped therein by spreading. A holding arm, which is integrally connected to the spring element, presses on the edge of an adjacent LED board to hold it to the body.

Die vorhergehend gezeigten Beispiele aus dem Stand der Technik ermöglichen es lediglich, die Platine punktuell, z.B. am Rand, zu halten. Dadurch wird jedoch nur ein geringer Anpressdruck auf die Platine ausgeübt. Es muss daher eine entsprechend hohe Stückzahl der Fixierungselemente verwendet werden. Der Anpressdruck ist u.a. besonders kritisch, weil bei Bildung eines Luftspalts zwischen der Platine und dem darunterliegenden Grundkörper keine ausreichende Kühlung der auf der Platine angeordneten LEDs mehr gegeben ist.The examples of the prior art shown above only make it possible to hold the board at points, eg at the edge. As a result, however, only a small contact pressure exercised on the board. It must therefore be used a correspondingly high number of fixing elements. The contact pressure is among other things particularly critical, because when forming an air gap between the board and the underlying body is no longer sufficient cooling of the arranged on the board LEDs more.

Aufgabe der vorliegenden Erfindung ist es daher, eine möglichst einfache und sichere Montage der Platine an der Tragschiene zu ermöglichen.Object of the present invention is therefore to enable the simplest and safest possible mounting of the board to the support rail.

Gelöst wird die Aufgabe durch eine Leuchte nach Anspruch 1.The problem is solved by a luminaire according to claim 1.

Eine Besonderheit der erfindungsgemäßen Leuchte besteht darin, dass Befestigungselemente zum Halten der Platine auf der Anlagefläche der Tragschiene verwendet werden, welche die Platine über die gesamte Breite übergreifen und an gegenüberliegenden Rändern der Anlagefläche an der Tragschiene mit dieser verbunden sind. Jedes Befestigungselement weist daher wenigstens zwei Verbindungspunkte an gegenüberliegenden Seiten der Platine zu der Tragschiene auf und drückt die Platine über deren gesamte Breite an die Anlagefläche der Tragschiene. Dadurch ist eine mechanisch sehr stabile Verbindung gegeben im Vergleich zu herkömmlichen Schrauben oder aus dem Stand der Technik bekannten Verbindungselementen, die nur punktförmig die Platine auf die Anlagefläche eines darunterliegenden Grundkörpers drücken. Das Befestigungselement eignet sich insbesondere für Tragschienen, weil die entlang einer Vorzugsrichtung immer gleiche Abstände zwischen den Rändern der LED-Platine definieren, so dass mehrere der Befestigungselemente auch hintereinander entlang der Längsrichtung der Schiene die LED-Platine halten können. Durch das Einspannen der Befestigungselemente an zwei gegenüberliegenden Rändern ist eine sichere Befestigung zu der Tragschiene gewährleistet. Es ist dabei insbesondere vorgesehen, dass die Befestigungselemente auch werkzeuglos mit der Tragschiene verbunden werden können, um die LED-Platine an der Anlagefläche zu halten.A special feature of the lamp according to the invention is that fasteners are used to hold the board on the contact surface of the support rail, which engage over the board over the entire width and are connected at opposite edges of the contact surface on the mounting rail with this. Each fastener therefore has at least two connection points on opposite sides of the board to the support rail and presses the board over the entire width of the contact surface of the support rail. As a result, a mechanically very stable connection is given in comparison to conventional screws or connecting elements known from the prior art, which only press the printed circuit board punctiform onto the contact surface of an underlying base body. The fastener is particularly suitable for mounting rails, because along a preferred direction always define the same distances between the edges of the LED board, so that several of the fasteners can also hold one behind the other along the longitudinal direction of the rail, the LED board. By clamping the fasteners on two opposite edges a secure attachment to the mounting rail is guaranteed. It is in particular provided that the fasteners can also be connected without tools to the mounting rail to hold the LED board to the contact surface.

Gemäß einer bevorzugten Ausführungsform ist das Befestigungselement auf einer der Längsseiten der Anlagefläche in eine Vertiefung der Tragschiene eingesteckt und greift auf der gegenüberliegenden Längsseite der Anlagefläche in eine Hinterschneidung der Tragschiene mit einem, vorzugsweise zwei, federelastischen Haken ein. Das Einstecken in eine Vertiefung auf einer Seite der Anlagefläche in der Tragschiene kann erfolgen, wenn das Befestigungselement in einem Winkel zu der Platine angeordnet ist. Anschließend bildet dieser Berührungspunkt zu der Tragschiene einen Drehpunkt für das Befestigungselement, um dieses in Richtung zu der Platine zu drehen und es mit federelastischen Haken auf der gegenüberliegenden Seite in Hinterschneidungen in der Tragschiene einzurasten. Die Montage des Befestigungselements kann auf diese Weise vollkommen werkzeuglos stattfinden. Da das Befestigungselement auf einer Seite nur eingehängt ist, kann es auch leicht durch Lösen der elastischen Haken wieder abgenommen werden. Es ist gemäß einer bevorzugten Ausführungsform auch möglich, dass die Hinterschneidungen auf beiden Seiten der Tragschiene identisch vorgesehen sind, was es ermöglicht, das Befestigungselement an einer beliebigen Stelle und in beliebiger Richtung entlang der Tragschiene zu montieren. Vorzugsweise sind jedoch Vertiefungen für Führungszapfen des Befestigungselements an einer der beiden Seiten vorgesehen, um die Positionierung des Befestigungselements an einer bestimmten Stelle der Tragschiene zu erleichtern.According to a preferred embodiment, the fastening element is inserted on one of the longitudinal sides of the contact surface in a recess of the support rail and engages on the opposite longitudinal side of the contact surface in an undercut of the support rail with one, preferably two, resilient hook. The insertion into a recess on one side of the contact surface in the mounting rail can be done when the fastener is arranged at an angle to the board. Subsequently, this point of contact with the mounting rail forms a pivot point for the fastening element in order to turn it in the direction of the circuit board and lock it with spring-elastic hooks on the opposite side into undercuts in the mounting rail. The mounting of the fastener can take place completely tool-free in this way. Since the fastener is only hung on one side, it can also be easily removed by loosening the elastic hook again. It is according to a preferred embodiment also possible that the undercuts are provided identically on both sides of the support rail, which makes it possible to mount the fastener at any point and in any direction along the support rail. Preferably, however, recesses are provided for guide pins of the fastener on one of the two sides to facilitate the positioning of the fastener at a certain point of the support rail.

Gemäß einer bevorzugten Ausführungsform weist die Leuchte wenigstens zwei Platinen auf, die an der Anlagefläche stirnseitig benachbart angeordnet sind, und das Befestigungselement übergreift beide Platinen über deren gesamte Breite an der Stirnseite beider Platinen. In dieser Ausführungsform dient ein Befestigungselement dazu, um zwei benachbarte Platinen an der Anlagefläche der Tragschiene zu halten. Dies verringert nicht nur die Anzahl der notwendigen Befestigungselemente, sondern ermöglicht es auch, die Platinen lagegenau zueinander an der Anlagefläche zu halten. Insbesondere kann an dem Befestigungselement ein Steg vorgesehen sein, welcher zwischen den zwei stirnseitig benachbarten Platinen im montierten Zustand des Befestigungselements liegt. Der Steg dient dazu, um die Platinen in einem definierten Abstand zueinander zu halten, wobei gleichzeitig ein Berühren der Platinen verhindert wird. Eine Berührung ist in der Regel unerwünscht, um unbeabsichtigte elektrische Kontakte zu verhindern. Ferner ist durch den Steg ein definierter Abstand zwischen den Platinen festgelegt, so dass auch die auf den Platinen angeordneten LEDs in einem definierten Abstand über die Platinen hinweg angeordnet sind. Gemäß einer Weiterbildung dieser Ausführungsform kann der Steg auch in einen Schlitz der Anlagefläche eingreifen. Dadurch ist die Position des Befestigungselements gegenüber der Tragschiene festgelegt. Der Steg kann bis zur gegenüberliegenden Seite der Tragschiene hinausstehen, um beispielsweise auf der gegenüberliegenden Seite auf einer weiteren Anlagefläche für Platinen als Abstandselement zu dienen.According to a preferred embodiment, the lamp has at least two boards, which are arranged adjacent to the contact surface on the front side, and the fastening element overlaps both boards over their entire width on the front side of both boards. In this embodiment, a fastener is used to hold two adjacent boards to the contact surface of the support rail. This not only reduces the number of necessary fasteners, but also makes it possible to keep the boards in position relative to each other on the contact surface. In particular, a web can be provided on the fastening element, which lies between the two end sides adjacent boards in the assembled state of the fastener. The web serves to keep the boards at a defined distance from each other, at the same time a touching of the boards is prevented. Touch is usually undesirable to prevent inadvertent electrical contact. Furthermore, a defined distance between the boards is determined by the web, so that the arranged on the boards LEDs are arranged at a defined distance across the boards away. According to a development of this embodiment, the web can also engage in a slot of the contact surface. As a result, the position of the fastening element relative to the mounting rail is fixed. The web can protrude to the opposite side of the mounting rail, for example, to serve on the opposite side on a further contact surface for boards as a spacer.

Gemäß einer bevorzugten Ausführungsform ist das Befestigungselement aus einem elektrisch isolierenden Material, insbesondere aus Kunststoff, gebildet. Durch das Befestigungselement wird damit eine elektrische Isolierung zwischen den Platinen bewirkt. Ferner bietet Kunststoff die Möglichkeit, elastische Haken oder andere Rastmittel an dem Befestigungselement einstückig anzuformen, da Kunststoff die notwendigen elastischen Eigenschaften aufweist. Alternativ könnte auch eine Stahlklammer als Befestigungselement dienen. Diese weist jedoch vorzugsweise eine elektrische Isolierung auf, da das Befestigungselement mit der Oberseite der Platinen, auf denen auch die spannungsführenden Teile der Platine angeordnet sind, in Kontakt kommt.According to a preferred embodiment, the fastening element is made of an electrically insulating material, in particular of plastic. By the fastener so that electrical insulation between the boards is effected. Furthermore, plastic offers the possibility of integrally forming elastic hooks or other latching means on the fastening element, since plastic has the necessary elastic properties. Alternatively, a steel clip could serve as a fastener. However, this preferably has an electrical insulation, since the fastener comes into contact with the top of the boards, on which the live parts of the board are arranged.

Gemäß einer bevorzugten Ausführungsform weist das Befestigungselement ein oder mehrere Zentrierelemente auf, welche in eine Aussparung der Platine und/oder der Tragschiene formschlüssig eingreifen. Insbesondere ist es von Vorteil, dass das Befestigungselement sowohl in die Platine als auch in eine Aussparung der Tragschiene eingreift, so dass auch die präzise Position der Platine gegenüber der Tragschiene bereits durch das Befestigungselement gewährleistet ist. Beispielsweise kann die Platine Ausschnitte an den Rändern aufweisen, in welchen zapfenförmige Vorsprünge des Befestigungselements eingreifen und sich bis in eine Vertiefung der Tragschiene erstrecken.According to a preferred embodiment, the fastening element has one or more centering elements, which engage in a form-fitting manner in a recess of the circuit board and / or the mounting rail. In particular, it is advantageous that the fastening element engages both in the circuit board and in a recess of the mounting rail, so that the precise position of the board against the mounting rail is already ensured by the fastener. For example, the board may have cutouts at the edges, in which engage peg-shaped projections of the fastener and extend into a recess of the support rail.

Gemäß einer bevorzugten Ausführungsform weist die Tragschiene auf wenigstens einer Längsseite der Anlagefläche ein durchgängiges Profil auf, in das das Befestigungselement mit einem elastischen Haken einschnappt, um das Befestigungselement an der Tragschiene zu halten. Das durchgängige Profil hat den Vorteil, dass das Befestigungselement im Prinzip an jeder Stelle der Tragschiene montiert werden kann. Ferner können auch in Verbindung mit der vorhergehend genannten Ausführungsform an verschiedenen Stellen der Tragschiene Aussparungen für Zentrierelemente des Befestigungselements vorgesehen sein. Dadurch lässt sich das Befestigungselement zwar nur an bestimmten Stellen der Tragschiene befestigen, jedoch können die tragschienenseitig vorgesehenen Aussparungen für unterschiedlich große bzw. lange Platinen standardgemäß vorgesehen sein, so dass die Tragschiene individuell mit unterschiedlichen Platinen bestückt werden kann.According to a preferred embodiment, the mounting rail on at least one longitudinal side of the contact surface on a continuous profile, in which the fastener snaps with an elastic hook to hold the fastener to the mounting rail. The continuous profile has the advantage that the fastener can be mounted in principle at any point of the mounting rail. Furthermore, recesses for centering elements of the fastening element can also be provided at different locations of the mounting rail in connection with the aforementioned embodiment. As a result, the fastening element can indeed be fastened only at certain locations of the mounting rail, however, the recesses provided for the rail side can be provided as standard for differently sized or long boards, so that the mounting rail can be fitted individually with different circuit boards.

Gemäß einer bevorzugten Ausführungsform weist das Befestigungselement einen die gesamte Breite der Platine übergreifenden Arm auf, wobei der Arm eine Breite in Längsrichtung der Tragschiene besitzt, die geringer ist als der Abstand zweier benachbarter LEDs auf den Platinen in der gleichen Richtung. Dadurch lässt sich das Befestigungselement über die Platine anordnen, ohne dass die Abstände der LEDs auf der Platine im Bereich des Befestigungselements verändert werden müssen. Von außen betrachtet ist eine kontinuierliche Reihe oder eine kontinuierliche Matrix von LEDs sichtbar, wobei das Befestigungselement nicht auffällt. Das gleiche gilt auch für Befestigungselemente, die zwei Stirnseiten von zwei benachbarten Platinen überbrücken. Auch in dieser Ausführungsform können die Abstände der LEDs zu dem jeweiligen Rand der Platine genauso ausgebildet sein, dass mit einem darüber angeordneten Befestigungselement von außen betrachtet ein kontinuierlicher Abstand der LEDs über die Platinen hinweg gebildet wird. Auf diese Weise entsteht auch bei aneinandergesetzten Platinen der Eindruck einer kontinuierlichen Aneinanderreihung von LEDs in einheitlichem Muster, z.B. in einer Reihe, mit kontinuierlichen Abständen.According to a preferred embodiment, the fastening element has an arm extending across the entire width of the board, wherein the arm has a width in the longitudinal direction of the mounting rail which is smaller than the distance between two adjacent LEDs on the boards in the same direction. As a result, the fastening element can be arranged over the circuit board without the spacing of the LEDs on the circuit board in the region of the fastening element having to be changed. Seen from the outside, a continuous row or continuous matrix of LEDs is visible, with the fastener not noticeable. The same applies to fasteners that span two faces of two adjacent boards. Also in this embodiment, the distances of the LEDs to the respective edge of the board can be designed in the same way that, viewed from the outside, a continuous spacing of the LEDs across the boards is formed with a fastener arranged above it. In this way, even when juxtaposed boards the impression of a continuous stringing of LEDs in a uniform pattern, e.g. in a row, with continuous intervals.

Gemäß einer bevorzugten Ausführungsform durchgreift das Befestigungselement eine Öffnung der Tragschiene bis zu einer der Anlagefläche entgegengesetzten Seite der Tragschiene und steht darüber hervor und weist auf der entgegengesetzten Seite der Tragschiene eine Arretierung auf. Beispielsweise können die Befestigungselement eine oder mehrere zapfenförmige Vorsprünge aufweisen, die auf der äußeren Seite mit einem elastischen Widerhaken versehen sind, der sich auf der der Anlagefläche der Tragschiene entgegengesetzten Seite verspreizt. Dadurch ist eine besonders feste Verbindung zwischen dem Befestigungselement und der Tragschiene gewährleistet.According to a preferred embodiment, the fastening element engages through an opening of the support rail to a support surface of the opposite side of the support rail and projects beyond it and has on the opposite side of the support rail on a lock. For example, the fastening element may have one or more pin-shaped projections, which are provided on the outer side with a resilient barb, which spreads on the opposite side of the contact surface of the support rail. As a result, a particularly firm connection between the fastening element and the mounting rail is ensured.

Gemäße einer Weiterbildung der vorhergehend genannten Ausführungsform geht die Arretierung insbesondere einen Reib- oder Formschluss mit der Platine ein und ist einstückig mit dem Befestigungselement ausgebildet. Dadurch dient die Arretierung gleichzeitig zum Ausrichten der Platinen auf der Anlagefläche entsprechend der Position des Befestigungselements auf der Tragschiene.According to a development of the aforementioned embodiment, the locking is in particular a frictional or positive connection with the board and is formed integrally with the fastening element. As a result, the lock is used at the same time for aligning the boards on the contact surface according to the position of the fastener on the mounting rail.

In der Figur 1 ist ein Befestigungselement 1 der vorliegenden Erfindung als einzelnes Bauteil dargestellt. Es umfasst einen Arm 2, welcher dafür bestimmt ist, über die gesamte Breite einer LED-Platine 20 angeordnet zu werden, wie in Figur 2 dargestellt. An einem Ende des Arms 2 ist eine schaufelförmige Verbreiterung 6 vorgesehen. An dem gegenüberliegenden Ende ist ein T-förmiger Abschnitt 4 vorgesehen, welcher zwei elastisch auslenkbare Haken 8 und mehrere, im dargestellten Beispiel drei, Erhöhungen 10 aufweist.In the FIG. 1 a fastener 1 of the present invention is shown as a single component. It comprises an arm 2, which is intended to be arranged over the entire width of an LED board 20, as in FIG. 2 shown. At one end of the arm 2, a blade-shaped widening 6 is provided. At the opposite end a T-shaped section 4 is provided, which two elastic deflectable hook 8 and a plurality, in the example shown three, 10 elevations.

Die Montage der Platinen 20 in einer Tragschiene 30 der Leuchte wird mit Bezug auf die Figuren 2 bis 4 beschrieben.The mounting of the boards 20 in a mounting rail 30 of the lamp is with reference to the FIGS. 2 to 4 described.

Die Tragschiene 30 ist vorzugsweise aus einem Aluminiumstandpressprofil hergestellt. Sie umfasst einen rinnenförmigen Kanal, welcher am Boden eine ebene Fläche definiert, die als Anlagefläche für die Platinen dient. Die Platinen 20 weisen eine Breite auf, welche der Breite der Anlagefläche entspricht. Mehrere der Platine 20 (in Figuren 2 und 4 sind jeweils nur zwei dargestellt) werden hintereinander auf die Anlagefläche der Tragschiene 30 angeordnet, so dass sie stirnseitig aneinander angrenzen. Zwischen jeweils zwei Platinen 20 wird das Befestigungselement 1 zunächst mit dem schaufelförmigen Abschnitt 6 in eine Hinterschneidung der Tragschiene 30 am Rand der Anlagefläche eingeführt, wie in den Figuren 3 und 4 dargestellt. Die Form der Hinterschneidung und des schaufelförmigen Abschnitts 6 des Befestigungselements 1 sind so aufeinander abgestimmt, dass das Befestigungselement 1 an der Hinterschneidung anliegend gedreht werden kann. Ferner sind die Platinen 20 an jeweils einer Ecke der Stirnseite ausgeschnitten, so dass der schaufelförmige Abschnitt 6 sich flach auf die Anlagefläche bewegen lässt. Das Befestigungselement 1 wird, wie in den Figuren 3 und 4 dargestellt, nach unten geschwenkt in Richtung zur Platine bis es mit den Haken 8 in eine gegenüberliegende Hinterschneidung der Tragschiene 30 einschnappt. Die Endposition des Befestigungselements 1 ist in Figur 2 dargestellt. Die Haken 8 des Befestigungselements 1 werden dabei federelastisch ausgelenkt und schnappen hinter der Hinterschneidung am Profilelement zurück, so dass ein sicherer Halt des Befestigungselement 1 der Tragschiene 30 gegeben ist. Im montierten Zustand übergreift demnach das Befestigungselement 1 vollständig die Breite der Platinen 20 im Bereich der Stirnseiten von jeweils benachbarten Platinen. Dadurch werden die Platinen über die gesamte Breite auf die Anlagefläche gedrückt. Dies ist von besonderem Vorteil, weil der Kontakt zu einer guten thermische Verbindung zwischen den Platinen 20 der Tragschien 30 führt. Dadurch kann die von LEDs 22 auf den Platinen erzeugte Wärme effektiv über die als Kühlkörper wirkende Tragschiene 30 abgeführt werden.The support rail 30 is preferably made of a Aluminiumstandpressprofil. It comprises a channel-shaped channel, which defines a flat surface at the bottom, which serves as a contact surface for the boards. The boards 20 have a width which corresponds to the width of the contact surface. Several of the board 20 (in Figures 2 and 4 each only two are shown) are arranged one behind the other on the contact surface of the support rail 30, so that they are adjacent to each other at the front. Between each two boards 20, the fastener 1 is first introduced with the paddle-shaped portion 6 in an undercut of the support rail 30 at the edge of the contact surface, as in the FIGS. 3 and 4 shown. The shape of the undercut and the blade-shaped portion 6 of the fastener 1 are coordinated so that the fastener 1 can be rotated adjacent to the undercut. Further, the boards 20 are cut out at each corner of the end face, so that the blade-shaped portion 6 can be moved flat on the contact surface. The fastener 1 is, as in the FIGS. 3 and 4 shown, pivoted down in the direction of the board until it snaps with the hooks 8 in an opposite undercut of the support rail 30. The end position of the fastener 1 is in FIG. 2 shown. The hooks 8 of the fastener 1 are thereby deflected resiliently and snap behind the undercut on the profile element, so that a secure hold of the fastener 1 of the support rail 30 is given. In the assembled state, therefore, the fastening element overlaps 1 completely the width of the boards 20 in the region of the end faces of each adjacent boards. As a result, the boards are pressed over the entire width of the contact surface. This is of particular advantage because the contact leads to a good thermal connection between the boards 20 of the mounting rails 30. As a result, the heat generated by LEDs 22 on the boards can be effectively dissipated via acting as a heat sink support rail 30.

Die LEDs 22 auf den Platinen 20 sind in einem regelmäßigen Abstand angeordnet, in der gezeigten Ausführungsform in einer mittigen Reihe. Die Breite des Arms 2 in Richtung der Anordnung der LEDs 22 ist dabei so gewählt, dass sie kleiner ist als der Abstand zweier LEDs. Ferner sind auch die an den Stirnseiten angeordneten LEDs vom stirnseitigen Rand der Platine so weit entfernt, dass bei benachbart angeordneten Platinen der Eindruck entsteht, dass die LED-Reihe ununterbrochen fortgesetzt wird. In der endgültig montierten Leuchte, in welcher noch eine Abdeckung an der Lichtaustrittsseite vorgesehen ist, ist dadurch das Befestigungselement 1 selbst nicht mehr erkennbar und es entsteht der Eindruck einer regelmäßigen Abfolge der LEDs 22 über mehrere Platinen hinweg.The LEDs 22 on the boards 20 are arranged at a regular interval, in the embodiment shown in a central row. The width of the arm 2 in the direction of the arrangement of the LEDs 22 is chosen so that it is smaller than the distance between two LEDs. Furthermore, the LEDs arranged on the end faces are also so far away from the front edge of the board that, when the boards are arranged adjacently, the impression is created that the row of LEDs will continue uninterrupted. In the final mounted light, in which a cover is still provided on the light exit side, thereby the fastener 1 itself is no longer recognizable and it creates the impression of a regular sequence of LEDs 22 across multiple boards away.

Das Befestigungselement 1 weist an dem Arm 2 ferner einen senkrecht zur Anlagefläche angerordneten Steg 12 auf, der sich in einen Spalt zwischen jeweils zwei benachbarten Platinen 20 einfügt. Da das Befestigungselement 1 aus einem isolierenden Material, insbesondere Kunststoff, hergestellt ist, wird dadurch effektiv eine Isolierung etwaiger spannungsführenden Elemente zwischen den zwei Platinen bewirkt. Ferner dient der Steg 12 auch dazu, einen definierten Abstand zwischen jeweils zwei Platinen zu gewährleisten, so dass die regelmäßige Abfolge der LEDs auch über die Grenze der zwei Platinen gegeben ist.The fastening element 1 also has on the arm 2 a web 12 which is perpendicular to the contact surface and which fits into a gap between two adjacent boards 20. Since the fastening element 1 is made of an insulating material, in particular plastic, this effectively causes insulation of any voltage-carrying elements between the two boards. Furthermore, the web 12 also serves to ensure a defined distance between each two boards, so that the regular sequence of LEDs is also given over the border of the two boards.

Das Befestigungselement 1 weist ferner mehrere Erhebungen 10 auf, welche dafür bestimmt sind, in Ausschnitte der Platine formschüssig einzugreifen, um die Platine 20 gegenüber dem Befestigungselement 1 in eine definierte Position zu bringen. Ferner können die Erhebungen 10 eine Höhe aufweisen (im Beispiel der Figur 1 die mittlere Erhebung 10), welche über die auf der Anlagefläche liegende Seite der Platine hinaussteht. Diese Erhebung greift in eine Öffnung der Anlagefläche in der Tragschiene 30 ein. Insbesondere kann vorgesehen sein, dass die Erhebung 10 reibschlüssig in einer Öffnung der Anlagefläche gehalten wird oder es kann sogar auf der der Platine entgegengesetzten Seite der Tragschiene eine zusätzliche Arretierung in Form von überstehenden Haken oder separaten Befestigungsmittels vorgesehen sein.The fastening element 1 also has a plurality of elevations 10, which are intended to form-fitting engage in cut-outs of the board in order to bring the board 20 relative to the fastening element 1 in a defined position. Furthermore, the elevations 10 may have a height (in the example of the FIG. 1 the middle elevation 10), which protrudes beyond the lying on the contact surface side of the board. This survey engages in an opening of the contact surface in the support rail 30 a. In particular, it may be provided that the elevation 10 is frictionally held in an opening of the contact surface or it may even be provided on the circuit board opposite side of the support rail, an additional locking in the form of protruding hook or separate fastener.

Die Befestigungselemente 1, wie vorhergehend beschrieben, haben daher den Vorteil, dass die Platinen 20 werkzeuglos an der Tragschiene 30 befestigt werden können. Separate Schrauben oder Nieten entfallen. Dies vereinfacht nicht nur die Montage der Platine sondern hat außerdem den Vorteil, dass keine überstehenden Schraub- oder Nietköpfe die Montage weiterer Bauteile behindert. Ferner ist ein Schraubkanal für Gewindegänge der Tragschiene nicht notwendig.The fastening elements 1, as described above, therefore have the advantage that the boards 20 can be attached to the mounting rail 30 without tools. Separate screws or rivets are eliminated. This not only simplifies the assembly of the board but also has the advantage that no protruding screw or rivet heads hinders the assembly of other components. Furthermore, a screw for threads of the mounting rail is not necessary.

Außerdem erlauben es die vorhergehend beschriebenen Befestigungselemente 1 auch, die Platinen nach erfolgter Montage wieder zu demontieren. Die Befestigungselemente 1 können von der Tragschiene werkzeuglos abgenommen werden. Dadurch ist das Austauschen einzelner Platinen, welche eine Fehlfunktion im Betrieb zeigen, selbst bei montierter Leuchte möglich.In addition, the previously described fasteners 1 also allow the boards to be dismantled after installation. The fasteners 1 can be removed from the mounting rail without tools. As a result, the replacement of individual boards, which show a malfunction during operation, even with mounted light possible.
