Description

Die Erfindung betrifft eine Leuchte mit wenigstens einer LED (lichtemittierende Diode) als einer Lichtquelle der Leuchte, einem Trägerelement, auf dem die wenigstens eine LED angeordnet ist sowie mit einem Leuchtengehäuse.The invention relates to a lamp with at least one LED (light emitting diode) as a light source of the lamp, a support element on which the at least one LED is arranged and with a lamp housing.

Bei einer derartigen Leuchte besteht das Problem, dass ein Wechsel der wenigstens einen LED nicht vorgesehen ist bzw. nur mit erheblichem Aufwand möglich ist. Insbesondere für einen Endverbraucher ist es hierdurch praktisch unmöglich, die wenigstens eine LED bzw. LEDs der Leuchte bei Bedarf zu wechseln.In such a luminaire, the problem is that a change of at least one LED is not provided or is possible only with considerable effort. In particular, for an end user, this makes it virtually impossible to change the at least one LED or LEDs of the light when needed.

Aus der US 2009/0168439 A1 ist eine Leuchte gemäß dem Oberbegriff des Anspruchs 1 bekannt, bei der ein Trägerelement mit darauf angeordneten LEDs reversibel in eine Ausnehmung einer kanalartigen Struktur eingesetzt werden kann.From the US 2009/0168439 A1 a luminaire according to the preamble of claim 1 is known in which a carrier element with LEDs arranged thereon can be reversibly inserted into a recess of a channel-like structure.

Der Erfindung liegt die Aufgabe zugrunde, eine entsprechende verbesserte Leuchte anzugeben; insbesondere soll die Handhabung der Leuchte mit Bezug auf einen Wechsel der Lichtquelle leichter möglich sein.The invention has for its object to provide a corresponding improved luminaire; In particular, the handling of the lamp with respect to a change of the light source should be easier.

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

Gemäß der Erfindung ist eine Leuchte vorgesehen, die wenigstens eine LED als eine Lichtquelle aufweist. Weiterhin weist die Leuchte ein Trägerelement auf, auf dem die wenigstens eine LED angeordnet ist, sowie ein Leuchtengehäuse. Das Leuchtengehäuse weist eine Ausnehmung auf, in der das Trägerelement reversibel lösbar eingesetzt ist.According to the invention, a luminaire is provided which has at least one LED as a light source. Furthermore, the lamp has a support element on which the at least one LED is arranged, and a lamp housing. The luminaire housing has a recess in which the support element is inserted reversibly detachable.

Durch diese Ausgestaltung der Leuchte ist es ermöglicht, das Trägerelement unter besonders geringem Aufwand von der restlichen Leuchte zu trennen und auf diese Weise insbesondere einen Wechsel der Lichtquelle vorzunehmen. Somit ist die Handhabung der Leuchte, insbesondere zum Wechsel der Lichtquelle erleichtert.This configuration of the lamp makes it possible to separate the support element from the rest of the lamp with particularly little effort and in this way to make a change in the light source in particular. Thus, the handling of the lamp, in particular for changing the light source is facilitated.

Erfindungsgemäß ist das Leuchtengehäuse wannenförmig und weist dabei eine Bodenwand und Seitenwände auf, wobei die Ausnehmung durch eine Öffnung in der Bodenwand gebildet ist. Auf diese Weise kann insbesondere durch das Trägerelement die Öffnung verschlossen sein, so dass das Leuchtengehäuse unter vergleichsweise wenig Materialaufwand gebildet sein kann. Das Leuchtengehäuse ist dabei aus einem Blechteil gebildet.According to the invention the lamp housing is trough-shaped and has a bottom wall and side walls, wherein the recess is formed by an opening in the bottom wall. In this way, in particular by the support member, the opening may be closed, so that the lamp housing can be formed under relatively little material cost. The luminaire housing is formed from a sheet metal part.

Vorteilhaft ist das Trägerelement derart ausgebildet, dass es zumindest im Wesentlichen die Ausnehmung verschließt. Hierdurch lässt sich ein wirksamer Schutz vor unerwünschtem Eintritt von Staubpartikeln und dergleichen in das Innere des Leuchtengehäuses erzielen.Advantageously, the carrier element is designed such that it at least substantially closes the recess. This makes it possible to achieve effective protection against undesired entry of dust particles and the like into the interior of the luminaire housing.

Vorzugsweise ist das Trägerelement als Profilkörper ausgebildet.Preferably, the carrier element is designed as a profile body.

Vorteilhaft liegt der Rand der Ausnehmung zumindest in erster Näherung in einer Ebene, wobei das Trägerelement ein zumindest in erster Näherung plattenförmiges Segment umfasst, das in der Ebene liegend orientiert angeordnet ist. Hierdurch ist ein einfaches Abdecken bzw. Verschließen der Ausnehmung durch das Trägerelement ermöglicht.Advantageously, the edge of the recess is at least in a first approximation in a plane, wherein the support member comprises a plate-shaped at least in the first approximation segment, which is arranged horizontally oriented lying in the plane. As a result, a simple covering or closing of the recess is made possible by the support element.

Weiterhin vorzugsweise bildet das Trägerelement einen Kühlkörper, der dazu ausgebildet ist, eine durch einen Betrieb der wenigstens einen LED entstehende Wärme abzuleiten. Hierdurch ist ein besonders effektiver Wärmeübergang von der wenigstens einen LED auf den Kühlkörper ermöglicht. Wenn das Trägerelement dabei in die Öffnung in der Bodenwand eingesetzt ist, ist außerdem eine besonders effektive Wärmeabgabe in einen Außenraum des Leuchtengehäuses, beispielsweise nach oben, ermöglicht.Further preferably, the support member forms a heat sink, which is adapted to dissipate a heat generated by an operation of the at least one LED. This allows a particularly effective heat transfer from the at least one LED to the heat sink. In addition, if the carrier element is inserted into the opening in the bottom wall, a particularly effective heat release into an outer space of the lamp housing, for example upwards, is made possible.

Vorzugsweise weist die Leuchte weiterhin eine zwischen dem Leuchtengehäuse und dem Trägerelement gebildete Schwenklageranordnung auf. Hierdurch ist eine besonders einfache Handhabung zum Lösen und Wiedereinsetzen des Trägerelements in die Ausnehmung bzw. in die Öffnung ermöglicht. Außerdem lässt sich auf diese Weise eine Montage der Leuchte vereinfachen, so dass sich insbesondere Montagekosten senken lassen. Vorzugsweise umfasst dabei die Schwenklageranordnung eine an dem Trägerelement und/oder an dem Leuchtengehäuse ausgebildete Nut. Hierdurch ist eine einfache Montage und dabei zuverlässige Lagerung des Trägerelements in der Ausnehmung ermöglicht.Preferably, the luminaire further comprises a pivot bearing arrangement formed between the luminaire housing and the carrier element. As a result, a particularly simple handling for releasing and reinserting of the carrier element in the recess or in the opening is made possible. In addition, can be simplified in this way a mounting of the lamp, so in particular Lower assembly costs. In this case, the pivot bearing arrangement preferably comprises one on the carrier element and / or on the Luminaire housing trained groove. As a result, a simple assembly and thereby reliable storage of the support element in the recess is possible.

Vorzugsweise ist die Nut länglich ausgebildet und dabei parallel zu der Längserstreckung des Profilkörpers.Preferably, the groove is elongate and parallel to the longitudinal extent of the profile body.

Vorzugsweise weist die Leuchte weiterhin eine zwischen dem Leuchtengehäuse und dem Trägerelement gebildete Schraubverbindungsanordnung auf. Hierdurch ist eine besonders zuverlässige und einfach herzustellende elektrische Verbindung zwischen dem Leuchtengehäuse und dem Trägerelement, insbesondere zur elektrischen Erdung, ermöglicht.Preferably, the luminaire further comprises a screw connection arrangement formed between the luminaire housing and the carrier element. As a result, a particularly reliable and easy to produce electrical connection between the lamp housing and the carrier element, in particular for electrical grounding, allows.

Vorteilhaft ist dabei die Schraubverbindungsanordnung mit Bezug auf das Trägerelement der Schwenklageranordnung gegenüberliegend ausgebildet. Hierdurch ist eine besonders einfache Handhabung beim Einsetzen des Trägerelements in die Ausnehmung des Leuchtengehäuses ermöglicht.Advantageously, the screw connection arrangement with respect to the support member of the pivot bearing assembly is formed opposite. This allows a particularly simple handling when inserting the carrier element in the recess of the lamp housing.

Vorzugsweise weist das Trägerelement weiterhin ein optisches Element auf, das zur optischen Beeinflussung eines von der wenigstens einen LED abgestrahlten Lichts ausgebildet ist. Hierdurch kann insbesondere ein wirksamer Schutz vor einem Berühren der wenigstens einen LED gebildet sein; außerdem ist auf diese Weise ein einfaches Austauschen dieses optischen Elements ermöglicht.Preferably, the carrier element further comprises an optical element which is designed to optically influence a light emitted by the at least one LED. In this way, in particular, an effective protection against touching the at least one LED can be formed; In addition, a simple replacement of this optical element is made possible in this way.

In Fig. 1 ist ein schematischer Querschnitt eines Ausführungsbeispiels einer erfindungsgemäßen Leuchte dargestellt; Fig. 2 zeigt einen entsprechenden Querschnitt durch das Leuchtengehäuse der Leuchte. Die Leuchte weist wenigstens eine LED 2 auf, die eine Lichtquelle der Leuchte bildet. Weiterhin weist die Leuchte ein Trägerelement 4 auf, auf dem die wenigstens eine LED 2 angeordnet ist. Hierzu kann insbesondere vorgesehen sein, dass - wie exemplarisch gezeigt - die wenigstens eine LED 2 auf einer Platine 22 angeordnet ist und die Platine 22 an dem Trägerelement 4.In Fig. 1 is a schematic cross section of an embodiment of a lamp according to the invention shown; Fig. 2 shows a corresponding cross section through the luminaire housing of the lamp. The lamp has at least one LED 2, which forms a light source of the lamp. Furthermore, the lamp has a carrier element 4, on which the at least one LED 2 is arranged. For this purpose, it can be provided, in particular, that-as is shown by way of example-the at least one LED 2 is arranged on a circuit board 22 and the circuit board 22 is arranged on the carrier element 4.

Weiterhin weist die Leuchte ein Leuchtengehäuse 6 auf. In Fig. 5 ist eine schematische, perspektivische Ansicht der Leuchte dargestellt. Wie dort beispielhaft gezeigt, kann das Leuchtengehäuse 6 insbesondere wannenförmig sein und eine Bodenwand 62, beispielsweise eine im Wesentlichen rechteckige Bodenwand 62, sowie Seitenwände 64, beispielsweise vier Seitenwände 64, aufweisen. Das Leuchtengehäuse 6 ist aus einem Blechteil gebildet. Die Seitenwände 64 können sich unmittelbar, vorzugsweise über Biegungen, an die Bodenwand 62 anschließen, so dass durch das Leuchtengehäuse 6 eine Quaderform festgelegt ist.

The side walls 64 may connect directly to the bottom wall 62, preferably by means of bends, so that a parallelepiped shape is defined by the luminaire housing 6. In this case, that square surface, which is opposite to the bottom wall 62, open be formed, and thereby form a light exit opening or a light exit area of the lamp. In particular, an optically active element 63 can be arranged in this light exit region, for example in the form of a secondary optic, which is designed to optically influence a light emitted by the at least one LED 2 before it leaves the luminaire. The luminaire may be a ceiling luminaire, in particular a recessed ceiling luminaire, but also a ceiling luminaire.

Die Leuchte kann für eine Lichtabgabe nach unten vorgesehen sein, so dass in der für den Betrieb vorgesehenen Orientierung der Leuchte die Bodenfläche 62 nach oben weist und die Lichtaustrittsöffnung dementsprechend nach unten. In diesem Sinne zeigt Fig. 5 eine Ansicht von schräg unten in einen inneren Bereich des Leuchtengehäuses 6.The lamp may be provided for a light output down, so that in the intended for the operation orientation of the lamp, the bottom surface 62 facing upward and the light exit opening accordingly downward. In this sense shows Fig. 5 a view obliquely from below into an inner region of the lamp housing. 6

In Fig. 7 ist eine schematische, perspektivische Darstellung von schräg unten in das geschnittene Leuchtengehäuse 6 dargestellt. Wie aus dieser Darstellung beispielhaft ersichtlich, kann die Leuchte als Lichtquelle mehrere LEDs 2 aufweisen, die insbesondere längs einer Geraden G angeordnet sein können. Die Gerade G kann dabei parallel zu einer der Seitenwände 64, vorzugsweise parallel zu zwei der Seitenwände 64 verlaufend orientiert sein.In Fig. 7 is a schematic, perspective view of obliquely below shown in the cut luminaire housing 6. As can be seen by way of example from this illustration, the luminaire can have as a light source a plurality of LEDs 2, which can be arranged in particular along a straight line G. The straight line G can be oriented parallel to one of the side walls 64, preferably parallel to two of the side walls 64.

Wie in den Figuren exemplarisch gezeigt, kann sich das Trägerelement 4 im Wesentlichen von einer ersten der Seitenwände 64 bis zu einer dazu gegenüberliegenden Seitenwand 64 erstrecken. Beispielsweise kann das Trägerelement 4 wenigstens 90% der entsprechenden Strecke einnehmen. Die LEDs 2 können sich dabei über den größten Bereich, insbesondere über wenigstens 80% der Längserstreckung des Trägerelements 4 längs der Geraden G erstrecken.As shown by way of example in the figures, the carrier element 4 can essentially extend from a first of the side walls 64 to a side wall 64 lying opposite thereto. For example, the carrier element 4 occupy at least 90% of the corresponding distance. The LEDs 2 can extend over the largest area, in particular over at least 80% of the longitudinal extent of the carrier element 4 along the straight line G.

In Fig. 6 ist das Leuchtengehäuse 6 und das Trägerelement 4 in einem vom Leuchtengehäuse 6 separierten Zustand skizziert. Das Leuchtengehäuse 6 weist eine, in Fig. 6 beispielhaft gezeigte, Ausnehmung 8 auf, in der das Trägerelement 4 reversibel lösbar eingesetzt werden kann bzw. - wie in Fig. 5 skizziert - im betriebsbereiten Zustand der Leuchte eingesetzt ist. Hierdurch ist ein besonders einfacher Wechsel der Lichtquelle bzw. der wenigstens einen LED 2 ermöglicht. Dabei ist die Ausnehmung 8 vorzugsweise durch eine Öffnung, insbesondere eine Durchgangsöffnung in der Bodenwand 62 gebildet. Beispielsweise kann die Ausgestaltung derart sein, dass die Öffnung mehr als 10% der, in das Innere des Leuchtengehäuses 6 weisenden Fläche der Bodenwand 62 einnimmt, und weniger als 90%. Vorzugsweise nimmt die Öffnung mehr als 25% und weniger als 75% der genannten Fläche ein.In Fig. 6 the luminaire housing 6 and the carrier element 4 is sketched in a state separated from the luminaire housing 6. The luminaire housing 6 has a, in Fig. 6 shown recess 8, in which the carrier element 4 can be used reversibly detachable or - as in Fig. 5 sketched - is used in the ready state of the lamp. This is a special simple change of the light source or the at least one LED 2 allows. In this case, the recess 8 is preferably formed by an opening, in particular a passage opening in the bottom wall 62. For example, the configuration may be such that the opening occupies more than 10% of the area of the bottom wall 62 pointing into the interior of the lamp housing 6, and less than 90%. Preferably, the opening occupies more than 25% and less than 75% of said area.

Wie im Ausführungsbeispiel exemplarisch gezeigt, ist das Trägerelement 4 vorzugsweise derart ausgebildet, dass es zumindest im Wesentlichen die Ausnehmung 8 bzw. die Öffnung verschließt. Mit "im Wesentlichen" sei dabei zum Ausdruck gebracht, dass das Trägerelement 4 beispielsweise wenigstens 90% oder 95%, vorzugsweise jedoch 100% der Ausnehmung 8 bzw. der Öffnung verschließt bzw. abdeckt. Hierdurch ist der Innenraum des Leuchtengehäuses 6 insbesondere vor einem ungewollten Eindringen von Schmutz oder dergleichen geschützt.As shown by way of example in the exemplary embodiment, the carrier element 4 is preferably designed such that it at least substantially closes the recess 8 or the opening. By "essentially" is expressed that the carrier element 4, for example, at least 90% or 95%, but preferably 100% of the recess 8 and the opening closes or covers. As a result, the interior of the lamp housing 6 is protected in particular against accidental ingress of dirt or the like.

Herstellungstechnisch vorteilhaft kann das Trägerelement 4 als Profilkörper ausgebildet sein, beispielsweise als Extrusionsprofil. Das Trägerelement 4 ist dabei vorzugweise derart gestaltet, dass die Längserstreckung des Profilelements und die Gerade G parallel verlaufen.In terms of manufacturing technology, the carrier element 4 can be formed as a profile body, for example as an extrusion profile. The carrier element 4 is preferably designed such that the longitudinal extent of the profile element and the straight line G are parallel.

Der Rand der Ausnehmung 8 liegt vorteilhaft zumindest in erster Näherung in einer, in Fig. 2 bezeichneten, Ebene E, wobei insbesondere die Bodenwand 62 plan gestaltet ist und dementsprechend ebenfalls in der Ebene E liegt. Das Trägerelement 4 weist dabei vorteilhaft ein zumindest in erster Näherung plattenförmiges Segment 45 auf, das ebenfalls in der Ebene E liegend orientiert angeordnet ist. Vorteilhaft weist das plattenförmige Segment 45 einen Rand auf, der mit dem Rand der Ausnehmung 8 derart korrespondiert, dass das in die Ausnehmung 8 eigesetzte Trägerelement 4 mit dem plattenförmigen Segment 45 die Ausnehmung 8 abdeckt. Hierdurch ist bei vergleichsweise wenig Materialaufwand für das Trägerelement 4 und unter einfacher Handhabung ein sicheres Abdecken der Ausnehmung 8 ermöglicht.The edge of the recess 8 is advantageous at least in a first approximation in one, in Fig. 2 designated level E, in particular, the bottom wall 62 is designed plan and accordingly also lies in the plane E. In this case, the carrier element 4 advantageously has a plate-shaped segment 45, at least in a first approximation, which is likewise oriented in the plane E oriented. Advantageously, the plate-shaped segment 45 has an edge which corresponds to the edge of the recess 8 in such a way that the support element 4 inserted into the recess 8 covers the recess 8 with the plate-shaped segment 45. As a result, a secure covering of the recess 8 is made possible with comparatively little material expenditure for the carrier element 4 and with simple handling.

Vorteilhaft bildet das Trägerelement 4 einen Kühlkörper 42, der dazu ausgebildet ist, eine durch einen Betrieb der wenigstens einen LED 2 entstehende Wärme effektiv abzuleiten. Der Kühlkörper 42 kann dementsprechend aus einem gut wärmeleitenden Material, wie beispielsweise Aluminium bestehen. Beispielsweise kann es sich bei dem Kühlkörper um einen Aluminium-Strangpresskörper handeln.Advantageously, the carrier element 4 forms a heat sink 42, which is designed to effectively dissipate a heat generated by an operation of the at least one LED 2 heat. The heat sink 42 may accordingly consist of a good heat-conducting material, such as aluminum. For example, the heat sink may be an aluminum extrusion.

Eine besonders wirksame Wärmeabfuhr ist ermöglicht, wenn der Kühlkörper 42 eine Fläche aufweist, die eine Außenfläche der Leuchte bildet, insbesondere durch einen nach außen weisenden Oberflächenbereich des plattenförmigen Segments 45. Im gezeigten Ausführungsbeispiel bildet der Kühlkörper 42 bzw. das plattenförmige Segment 45 des Kühlkörpers 4 eine nach außen oben weisende Außenfläche der Leuchte. Die gegenüberliegende Oberfläche des plattenförmigen Segments 45 weist in einen Innenbereich des Leuchtengehäuses 6 und trägt die Platine 22 mit den LEDs 2.A particularly effective heat dissipation is made possible when the heat sink 42 has a surface forming an outer surface of the lamp, in particular by an outwardly facing surface region of the plate-shaped segment 45. In the illustrated embodiment forms the heat sink 42 and the plate-shaped segment 45 of the heat sink 4th an outwardly facing outer surface of the lamp. The opposite surface of the plate-shaped segment 45 points into an inner region of the luminaire housing 6 and carries the circuit board 22 with the LEDs 2.

Eine besonders einfache Handhabung bei einem Wechsel der Lichtquelle ist ermöglicht, wenn zwischen dem Leuchtengehäuse 6 und dem Trägerelement 4 eine, beispielhaft in Fig. 2 bezeichnete, Schwenklageranordnung 10 gebildet ist. In Fig. 4 ist diese näher dargestellt. Hierdurch ist ein einfaches Ein- und Ausschwenken des Trägerelements 4 mit Bezug auf die Ausnehmung 8 bzw. die Öffnung ermöglicht. Bei der Schwenklageranordnung 10 kann es sich insbesondere um eine reversibel lösbare Schwenklageranordnung 10 handeln. Eine besonders handhabungsfreundliche und dabei herstellungstechnisch einfache Ausgestaltung ist ermöglicht, wenn die Schwenklageranordnung 10 eine an dem Trägerelement 4 ausgebildete Nut 12 umfasst. Die Nut 12 kann insbesondere länglich und dabei parallel zu der Geraden G bzw. parallel zu der Längserstreckung des Profilkörpers ausgebildet sein.A particularly simple handling when changing the light source is made possible when between the lamp housing 6 and the support member 4 a, for example in Fig. 2 designated, pivot bearing assembly 10 is formed. In Fig. 4 this is shown in more detail. As a result, a simple pivoting in and out of the carrier element 4 with respect to the recess 8 and the opening allows. The pivot bearing arrangement 10 can in particular be a reversibly detachable pivot bearing arrangement 10. A particularly easy-handling and manufacturing technology simple design is made possible when the pivot bearing assembly 10 comprises a formed on the support member 4 groove 12. The groove 12 may in particular be elongated and parallel to the straight line G or parallel to the longitudinal extent of the profile body.

Die Nut 12 kann insbesondere so ausgebildet sein, dass sie in einen korrespondierenden Randbereich der Ausnehmung 8 eingreifen kann, so dass auf diese Weise die Schwenklageranordnung 10 gebildet ist. Insbesondere kann die Nut 12 an einem Randbereich des plattenförmigen Segments 45 ausgebildet sein. Das Trägerelement 4 kann dann zur Montage zunächst mit der Nut 12 an dem entsprechenden Bereich des Rands der Ausnehmung 8 angelegt werden und im Weiteren durch Unterstützung der Schwenklageranordnung 10 einfach in die Ebene E geschwenkt werden, bis es die Ausnehmung 6 entsprechend abdeckt.The groove 12 may in particular be formed so that it can engage in a corresponding edge region of the recess 8, so that in this way the pivot bearing assembly 10 is formed. In particular, the groove 12 may be formed at an edge region of the plate-shaped segment 45. The carrier element 4 can then be applied for assembly first with the groove 12 at the corresponding region of the edge of the recess 8 and in Further, by supporting the pivot bearing assembly 10 simply be pivoted in the plane E until it covers the recess 6 accordingly.

Alternativ kann auch (in den Figuren nicht gezeigt) eine entsprechende Nut an einem Randbereich der Ausnehmung 8 angeordnet sein, in die ein korrespondierender Randbereich des Trägerelements 4 eingreifen kann.Alternatively, it is also possible (not shown in the figures) for a corresponding groove to be arranged on an edge region of the recess 8 into which a corresponding edge region of the carrier element 4 can engage.

Weiterhin vorteilhaft weist die Leuchte außerdem eine zwischen dem Leuchtengehäuse 6 und dem Trägerelement 4 gebildete Schraubverbindungsanordnung 14 auf. Diese ist exemplarisch in Fig. 3 näher dargestellt. Die Schraubverbindungsanordnung 14 kann für eine einfache Handhabung wenigstens eine Schraube aufweisen, deren Kopf mit Bezug auf das Leuchtengehäuse 6 nach innen weist, so dass ein Lösen der Schraube von innen her möglich ist. Die Schraubverbindungsanordnung 14 kann mehrere, vorzugsweise gleichartig angeordnete Schrauben aufweisen, die längs einer Linie angeordnet sind, die parallel zu der Geraden G verläuft.Further advantageously, the lamp also has a screw connection arrangement 14 formed between the luminaire housing 6 and the carrier element 4. This is exemplary in Fig. 3 shown in more detail. The screw connection assembly 14 may include at least one screw for ease of handling, the head of which faces inwardly with respect to the lamp housing 6, so that detachment of the screw from the inside is possible. The threaded connection assembly 14 may comprise a plurality of, preferably similarly arranged, screws arranged along a line parallel to the straight line G.

Durch eine solche Schraubverbindung wird ein zuverlässiger elektrischer Kontakt zwischen dem Leuchtengehäuse 6 einerseits und dem Trägerelement 4 andererseits ermöglicht, insbesondere zur elektrischen Erdung. Außerdem ist durch die Schraubverbindung eine Verbindung ermöglicht, die vergleichsweise einfach in der Handhabung ist und dabei das Trägerelement 4 zuverlässig in der Ausnehmung 8 in der Bodenwand 62 hält.By such a screw reliable electrical contact between the lamp housing 6 on the one hand and the support member 4 on the other hand allows, in particular for electrical grounding. In addition, a connection is made possible by the screw connection, which is relatively easy to handle while reliably holding the carrier element 4 in the recess 8 in the bottom wall 62.

Besonders vorteilhaft ist dabei die Schraubverbindungsanordnung 14 mit Bezug auf das Trägerelement 4, insbesondere mit Bezug auf die LED 2 oder die Gerade G, der Schwenklageranordnung 10 gegenüberliegend ausgebildet. Beispielsweise kann, wie exemplarisch gezeigt, mit Bezug auf die Gerade G, längs der die LEDs 2 angeordnet sind, die Schwenklageranordnung 10 auf einer Seite ausgebildet sein und die Schraubverbindungsanordnung 14 auf der gegenüberliegenden Seite. Hierdurch sind am Trägerelement 4 sozusagen eine "bewegliche" Seite und eine "fixe" Seite gebildet, wodurch sich Montagekosten verringern lassen und außerdem ein besonders einfaches Wechseln der Lichtquelle ermöglicht ist.Particularly advantageous is the screw connection assembly 14 with respect to the support member 4, in particular with respect to the LED 2 or the straight line G, the pivot bearing assembly 10 is formed opposite. For example, as exemplarily shown, with respect to the straight line G along which the LEDs 2 are disposed, the pivot bearing assembly 10 may be formed on one side and the threaded connection assembly 14 on the opposite side. As a result, as it were, a "movable" side and a "fixed" side are formed on the support element 4, which can reduce installation costs and also a particularly simple change of the light source is possible.

Alternativ ist es möglich, zu beiden Seiten der Geraden G jeweils eine entsprechende Schraubverbindung vorzusehen, allerdings ist in diesem Fall der Einbau bzw. die Montage im Allgemeinen mit mehr Aufwand verbunden.Alternatively, it is possible to provide in each case a corresponding screw connection on both sides of the straight line G, but in this case installation or assembly is generally associated with more effort.

Das Trägerelement 4 kann außerdem ein primär optische wirksames Element 16 aufweisen, beispielsweise in Form eines extrudierten Kunststoffprofils, das dazu ausgebildet ist, ein von der wenigstens einen LED 2 angestrahltes Licht optisch zu beeinflussen. Beispielsweise kann dieses optische Element 16 diffus wirkend ausgebildet sein, so dass die längs der Geraden G angeordneten LEDs 2 bei Betrachtung des optischen Elements 16 nicht mehr als einzelne punktuelle Lichtquellen erscheinen, sondern zumindest im Wesentlichen als eine längliche, leuchtende Linie.The carrier element 4 can also have a primarily optically effective element 16, for example in the form of an extruded plastic profile, which is designed to optically influence a light illuminated by the at least one LED 2. By way of example, this optical element 16 may have a diffuse effect, so that the LEDs 2 arranged along the straight line G no longer appear as individual point sources of light when viewing the optical element 16, but at least substantially as an elongated, luminous line.

Die Platine 22 kann mit elektrischen Kabeln zur Stromversorgung der LED 2 verbunden sein, die sich nach einer Montage des Trägerelements 4 in der Bodenwand 62 mit einem, in dem Leuchtengehäuse 6 angeordneten Betriebsgerät verbunden werden können, so dass die Montage der Lichtquelle und die Herstellung der Stromversorgung hierdurch abgeschlossen ist.The board 22 may be connected to electrical cables for powering the LED 2, which can be connected after installation of the support member 4 in the bottom wall 62 with a, arranged in the lamp housing 6 operating device, so that the assembly of the light source and the production of Power supply is thereby completed.
