Description

Die vorliegende Erfindung betrifft eine Leuchte mit einem Leuchtengehäuse und einer transparenten Abdeckung, welche das Leuchtengehäuse an einer Lichtaustrittsseite verschließt.The present invention relates to a luminaire with a luminaire housing and a transparent cover which closes the luminaire housing at a light exit side.

Leuchten der eingangs genannten Art werden als Innen- oder Außenleuchten, insbesondere als Wand- oder Deckenleuchten eingesetzt. Abhängig vom Einsatzort ist zum Schutz der Leuchtenbauteile häufig eine feuchtigkeitsdichte oder staubdichte Abdichtung zwischen dem Gehäuse und der transparenten Abdeckung wünschenswert. Beispielsweise sind Feuchtraumleuchten bekannt, welche auf der Gehäuseaußenseite Kniehebelverschlüsse aufweisen, um die transparente Abdeckung an einen umlaufenden Rand auf eine Dichtung an dem Gehäuse zu pressen. Aufgrund der außenliegenden Verschlüsse sind derartige Leuchten häufig weniger ästhetisch ansprechend. Ferner sind die Kniehebelverschlüsse verhältnismäßig umständlich zu betätigen, weil der Monteur einerseits die Abdeckung des Gehäuses halten muss und andererseits die Kniehebelverschlüsse nacheinander schließen muss.Lights of the type mentioned are used as indoor or outdoor lights, especially as wall or ceiling lights. Depending on the location, a moisture-proof or dust-tight seal between the housing and the transparent cover is often desirable for the protection of the lighting components. For example, wet room lights are known, which have on the outside of the housing knee lever locks to press the transparent cover to a peripheral edge on a seal on the housing. Due to the external closures such lights are often less aesthetically pleasing. Furthermore, the toggle locks are relatively cumbersome to operate, because the fitter on the one hand must hold the cover of the housing and on the other hand, the toggle locks must close successively.

Gemäß einer bevorzugten Ausführungsform ist das Verschlusselement separat von dem Gehäuse gebildet und in einem Ausschnitt der Seitenwand gehalten. Das Verschlusselement lässt sich auf diese Weise kostengünstig herstellen. Vorzugsweise ist das Verschlusselement vom Gehäuseinneren in dem Ausschnitt der Seitenwand montierbar. Das hat den Vorteil, dass bei der Herstellung der Leuchte das Gehäuse nicht gedreht werden muss. Außerdem kann auch später das Verschlusselement von der Innenseite der Leuchte gewechselt werden, ohne dass eine Demontage einer Einbauleuchte zum Auswechseln des Verschlusselementes notwendig wird. Gemäß weiteren Ausführungsformen ist es bevorzugt, dass es die Anordnung des Verschlusselements in dem Ausschnitt der Seitenwand ermöglicht, auf das Federelement des Verschlusselements von der Außenseite, z.B. zum Öffnen der Verriegelung, zuzugreifen.According to a preferred embodiment, the closure element is formed separately from the housing and held in a section of the side wall. The closure element can be produced inexpensively in this way. Preferably, the closure element from the housing interior in the cutout of the side wall can be mounted. This has the advantage that in the manufacture of the lamp, the housing does not have to be rotated.

Als Blech wird ein Federstahl verwendet, der die für das Federelement notwendige Elastizität aufweist.According to a preferred embodiment, the closure element is formed from a single sheet-metal stamped part. As a sheet metal spring steel is used, which has the necessary elasticity for the spring element.

Gemäß einer bevorzugten Weiterbildung der genannten Ausführungsform ist das gehäuseseitige Verschlusselement in wenigstens zwei, bevorzugt vier, Schlitze in der Gehäusewand eingesteckt. Beispielsweise kann das gehäuseseitige Verschlusselement in Form eines Blechbiegstanzteils zwei oder vier Haken aufweisen, die in zwei oder vier Schlitze, jeweils ein oder zwei zu beiden Seiten eines Ausschnitts in der Gehäusewand, eingehakt werden. Es sind wenigstens vier Schlitze bevorzugt, um ein Verdrehen oder ein Verkanten des Verschlusselements in der Montageposition in der Gehäuseseitenwand zu verhindern. Gemäß einer bevorzugten Ausführungsform erstrecken sich die Haken des Verschlusselements entgegen einer Richtung der Federvorspannung, d.h. die Haken des Verschlusselements erstrecken sich von der Gehäuseinnenseite durch die Seitenwand nach außen. Dadurch wird das Montieren des Verschlusselements vom Inneren der Leuchte ermöglicht. Bevorzugt weisen die Hinterschneidungen der Haken im Blechbiegestanzteil in die gleiche Richtung, wie die Einsteckrichtung der Abdeckeinrichtung auf das Gehäuse. Dadurch werden die gehäuseseitigen Verschlusselemente beim Einstecken der transparenten Abdeckung nicht aus ihrer Montageposition in der Gehäuseseitenwand herausgeschoben. Ferner kann das gehäuseseitige Verschlusselement wenigstens ein oder zwei, vorzugsweise gegenüber der Gehäuseseitenwand abgewinkelte Anschläge aufweisen, die an einer Kante der Gehäuseseitenwand anstoßen, wenn das gehäuseseitige Verschlusselement beim Abziehen der Abdeckung aus dem Gehäuse in Richtung zur Abdeckung bewegt wird.According to a preferred embodiment of said embodiment, the housing-side closure element is inserted into at least two, preferably four, slots in the housing wall.

Gemäß einer bevorzugten Ausführungsform weist das Federelement eine Anlaufschräge auf, die mit dem Haken beim Einführen der Abdeckung zusammenwirkt, um das Federelement entlang eines Federwegs in Richtung gegen den Haken auszulenken. Bei dieser Ausführungsform kann die Abdeckung in das Gehäuse eingesteckt werden, ohne dass ein Ergreifen des Federelements zum Verriegeln der Abdeckung notwendig ist. Die Abdeckung rastet an allen Haken in den zugeordneten Verschlusselementen selbständig ein.According to a preferred embodiment, the spring element on a run-on slope, which cooperates with the hook during insertion of the cover to deflect the spring element along a spring travel in the direction against the hook. In this embodiment, the cover can be inserted into the housing without gripping the Spring element for locking the cover is necessary. The cover engages independently on all hooks in the associated closure elements.

Gemäß einer bevorzugten Ausführungsform sind seitlich neben dem Federelement eine oder zwei Einführstege vorgesehen, welche die Positionierung des jeweiligen Hakens der Abdeckung an dem Federelement zum Verriegeln des Hakens erleichtern.According to a preferred embodiment, one or two insertion webs are provided laterally next to the spring element, which facilitate the positioning of the respective hook of the cover on the spring element for locking the hook.

Gemäß einer bevorzugten Ausführungsform weist das Federelement eine zurückspringende Kante auf, welche im montierten Zustand der Abdeckung an einer Kante des Hakens anliegt. Dadurch wird eine Rastverbindung zwischen dem Haken und dem Federelement gewährleistet, die einem Abrücken der Abdeckung von dem Gehäuse entgegenwirkt. Nach einer bevorzugten Weiterbildung dieser Ausführungsform schließt die Kante des Federelements und/oder des Hakens mit der Seitenwand einen Winkel, gemessen auf der von der Abdeckung abgewandten Seite, von mehr als 90° ein. Bei dieser Ausführungsform ist auch ein Demontieren der Abdeckung entgegen der Einschiebbewegung des Hakens in das Verschlusselement möglich, weil der stumpfe Winkel zwischen den verrasteten Kanten ein selbständiges Zurückfedern des Federelements ermöglicht, wenn eine Kraft auf die transparente Abdeckung entgegen der Einsteckbewegung ausgeübt wird. Durch die genaue Wahl des Winkels lässt sich die zum Demontieren der Abdeckung notwendige Kraft einstellen. Bei einem Winkel, der sehr nah an 90° liegt, ist die Kraft zum Abziehen der Abdeckung verhältnismäßig hoch. Bei stumpferen Winkeln ist die Kraft zum Demontieren der Abdeckung entsprechend niedriger.According to a preferred embodiment, the spring element has a recessed edge, which rests in the mounted state of the cover on an edge of the hook. This ensures a latching connection between the hook and the spring element, which counteracts a removal of the cover from the housing. According to a preferred embodiment of this embodiment, the edge of the spring element and / or the hook with the side wall forms an angle, measured on the side facing away from the cover, of more than 90 °. In this embodiment, a disassembly of the cover against the Einschiebbewegung of the hook is possible in the closure element, because the obtuse angle between the latched edges allows an independent spring back of the spring element when a force is exerted on the transparent cover against the insertion movement. By the exact choice of the angle, the force necessary to disassemble the cover can be adjusted. At an angle that is very close to 90 °, the force to pull off the cover is relatively high. At blunt angles, the force to disassemble the cover is correspondingly lower.

Gemäß bevorzugten Ausführungsform definiert die Lage des Verschlusselements in dem Gehäuse den Tiefenanschlag der Abdeckung. Beispielsweise kann eine Kante von einem oder zwei der vorhergehend genannten Führungsstege des Verschlusselements als Tiefenanschlag für die Abdeckung dienen. Diese Ausführungsform hat den Vorteil, dass die Montageposition der Abdeckung unabhängig von der Federkraft des Federelements definiert ist.According to a preferred embodiment, the position of the closure element in the housing defines the depth stop of the cover. For example, an edge of one or two of the aforementioned guide webs of the closure element can serve as a depth stop for the cover. This embodiment has the advantage that the mounting position of the cover is defined independently of the spring force of the spring element.

Gemäß einer bevorzugten Ausführungsform ist zwischen einem Rand der Abdeckung und der Gehäuseseitenwand eine elastische Dichtung vorgesehen. Eine Dichtung wird zwischen dem Rand der Abdeckung und der Gehäuseseitenwand eingequetscht. Dies dient nicht nur zum Dichten, sondern kann auch durch die Reibungskraft zwischen dem Rand der Abdeckung und der Gehäuseseitenwand dafür sorgen, dass die Kräfte zum Abziehen der Abdeckung von dem Verschlusselement erhöht wird.According to a preferred embodiment, an elastic seal is provided between an edge of the cover and the side wall of the housing. A gasket is squeezed between the edge of the cover and the side wall of the housing. This not only serves to seal, but can also ensure, by the frictional force between the edge of the cover and the side wall of the housing, that the forces for pulling off the cover from the closure element are increased.

Bezug nehmend auf Figur 1 ist eine transparente Abdeckung 2 einer Leuchte gemäß einer Ausführungsform der Erfindung dargestellt. Die transparente Abdeckung 2 ist durch eine im Wesentlichen ebene Platte gebildet, die aus einem transparenten Kunststoff, insbesondere PMMA, hergestellt ist. Die Abdeckung 2 weist auf der zum Gehäuse (in den Figuren 1 und 2 nicht dargestellt) weisenden Seite einen umlaufenden Rand auf, an dem sich in Richtung zum Gehäuse weisend mehrere Haken 4 anschließen. Die Haken 4, welche integral mit der Abdeckung aufgebildet sind, dienen zur Verriegelung der Abdeckung 2 mit einem Leuchtengehäuse. Genauer gesagt dienen die Haken 4 zur Verbindung mit gehäuseseitigen Verschlusselementen 6, die in einem Ausschnitt einer Seitenwand 8 des Gehäuses integriert sind, wie in Figur 3, welche einen Ausschnitt einer Gehäuseseitenwand 8 zeigt, dargestellt ist.Referring to FIG. 1 a transparent cover 2 of a luminaire according to an embodiment of the invention is shown. The transparent cover 2 is formed by a substantially flat plate, which is made of a transparent plastic, in particular PMMA. The cover 2 has on the housing (in the Figures 1 and 2 not shown) side facing a circumferential edge, at which point towards the housing several hooks 4 connect. The hooks 4, which are formed integrally with the cover, serve to lock the cover 2 with a lamp housing. More specifically, the hooks 4 are for connection to housing-side shutter members 6 integrated in a cutout of a side wall 8 of the housing, as in FIG FIG. 3 , which shows a section of a housing side wall 8, is shown.

Jeder der Haken 4 weist eine Anlaufschräge 10 und eine zurückspringende Kante 12 auf, welche mit einem Federelement 14 des Verschlusselements 6 zusammenwirken, um eine kraftschlüssige Verbindung zwischen dem Haken 4 und dem Federelement 14 zu bilden.Each of the hooks 4 has a run-on slope 10 and a recessed edge 12, which cooperate with a spring element 14 of the closure element 6 in order to form a frictional connection between the hook 4 and the spring element 14.

Das Federelement 14 des Verschlusselements 6 weist ebenfalls eine Anlaufschräge 16 auf, die etwa dem Winkel der Anlaufschräge 10 gegenüber der Seitenwand 8 entspricht. Ferner weist das Federelement 14 eine zurückspringende Kante 18 auf, welche etwa den gleichen Winkel gegenüber der Seitenwand 8 einnimmt wie die zurückspringende Kante 12 des Hakens 4. Zum Einrückung der Abdeckung an dem Gehäuse wird durch den Kontakt der Anlaufschräge 10 mit der Anlaufschräge 16 das Federelement 14 vom Gehäuseinneren nach außen ausgelenkt, bis die zurückspringende Kante 18 des Federelements 14 über der Kante 12 des Hakens 4 einrastet. Der im Federelement 14 eingerastete Haken 4 ist in einem Querschnitt in Figur 5 dargestellt.The spring element 14 of the closure element 6 also has a run-on slope 16, which corresponds approximately to the angle of the run-on slope 10 relative to the side wall 8. Further, the spring element 14 has a recessed edge 18, which occupies about the same angle relative to the side wall 8 as the recessed edge 12 of the hook 4. To indentation of the cover to the housing by the contact of the run-on slope 10 with the run-on slope 16, the spring element 14 deflected from the inside of the housing to the outside until the recessed edge 18 of the spring element 14 engages over the edge 12 of the hook 4. The latched in the spring element 14 hook 4 is in a cross section in FIG. 5 shown.

Das Verschlusselement 6 ist aus einem einzelnen Blechbiegestanzteil aus einem Federstahl gefertigt. Es wird in einem Ausschnitt in der Seitenwand 8 des Leuchtengehäuses befestigt. Wie in den Figuren 3 und 4 dargestellt ist, weist die Seitenwand 8 einen Ausschnitt 20 auf, der an die Form des Federelements 14 angepasst ist. Seitlich zum Ausschnitt 20 sind ferner vier Schlitze 22 und 23 ausgebildet, wobei die unteren Schlitze 23 zum leichteren Einführen des Verschlusselements 6 einen keilförmigen Ausschnitt aufweisen. Das Verschlusselement 6 weist vier, aus einem einfachen Blechabschnitt hergestellte Haken 24 (siehe Figur 5) auf, mit denen das Verschlusselement in die Schlitze 22 eingesteckt wird. Vorzugsweise weist die Hinterschneidung des Hakens 24 in eine Richtung, welche von der Abdeckung 4 abgewandt ist. Dadurch wird beim Einrücken der Abdeckung 4 in die Verschlusselemente 6 das Verschlusselement nicht aus einer Montageposition der Seitenwand 8 bewegt. Die unteren der beiden Haken 24 weisen einen nach außen gerichteten V-förmigen Abschnitt 25 auf (senkrecht zur Bildebene der Figur 4), wobei der V-förmige Abschnitt 25 die Seitenwand 8 von beiden Seiten umgreift, um das Verschlusselement zu stabilisieren. Die V-förmigen Abschnitte 25 können in beiden Schlitze 23 eingefügt werden, da die Schlitze 23 einen keilförmigen Ausschnitt aufweisen.The closure element 6 is made of a single sheet metal stamping made of a spring steel. It is fastened in a cutout in the side wall 8 of the luminaire housing. As in the Figures 3 and 4 is shown, the side wall 8 a cutout 20 which is adapted to the shape of the spring element 14. Four slots 22 and 23 are also formed laterally to the cutout 20, wherein the lower slots 23 have a wedge-shaped cutout for easier insertion of the closure element 6. The closure element 6 has four, made of a simple sheet metal hook 24 (see FIG. 5 ), with which the closure element is inserted into the slots 22. Preferably, the undercut of the hook 24 in a direction which faces away from the cover 4. As a result, when the cover 4 is engaged in the closure elements 6, the closure element is not moved out of a mounting position of the side wall 8. The lower of the two hooks 24 have an outwardly directed V-shaped portion 25 (perpendicular to the image plane of FIG. 4 ), wherein the V-shaped portion 25 surrounds the side wall 8 from both sides to stabilize the closure member. The V-shaped portions 25 can be inserted in both slots 23, since the slots 23 have a wedge-shaped cutout.

Das Verschlusselement 6 weist ferner zwei abgewinkelte Blechzungen 28 auf, die durch eine Abkantung (aus der Bildebene der Figur 4 heraus) einen Anschlag gegenüber einen nach innen vorspringenden Rand des Ausschnitts 20 definieren, wenn der untere Bereich des Verschlusselements 6 durch die Wirkung des ausgelenkten Federelements tordiert wird. Durch die Blechzungen 28 wird ein Ausrücken des Federelements entgegen der Einsteckbewegung der Haken 24 in die Schlitze 22 verhindert.The closure element 6 also has two angled sheet metal tongues 28, which by a fold (from the image plane of FIG. 4 out) define a stop against an inwardly projecting edge of the cutout 20 when the lower portion of the closure member 6 is twisted by the action of the deflected spring member. By the sheet metal tongues 28 disengagement of the spring element against the insertion movement of the hook 24 is prevented in the slots 22.

Ferner weist das Verschlusselement 6 zwei Blechzungen 30 auf, die als seitliche Führungsstege 30 zum Einrücken des Hakens 4 dienen. Die Blechzungen 30 weisen von dem Verschlusselement 6 aus in der Seitenwand 8 in Richtung zur Gehäuseinnenseite hinein. Wenn beim Einführen der Abdeckung 2 die Haken 4 nicht exakt mit den gehäuseseitigen Verschlusselementen 6 fluchten, werden durch die Führungsstege 30 die Haken 4 in Richtung zu dem Federelement 14 seitlich geführt. Gleichzeitig definiert der zur Abdeckung weisende Rand der zwei Blechzungen 20 den Tiefenanschlag der Abdeckung. Dabei ist von Vorteil, dass der Tiefenanschlag und das Federelement 14 integral in dem Verschlusselement 6 ausgebildet sind, um Fertigungstoleranzen auszuschließen. Solche Toleranzen können zu einem undefinierten Kraftschluss zwischen dem Federelement 14 und dem Haken 4 führen.Furthermore, the closure element 6 has two sheet metal tongues 30, which serve as lateral guide webs 30 for engaging the hook 4. The sheet metal tongues 30 point from the closure element 6 in the side wall 8 in the direction of the inside of the housing. If, during insertion of the cover 2, the hooks 4 are not exactly aligned with the housing-side closure elements 6, the hooks 4 are guided laterally in the direction of the spring element 14 by the guide webs 30. At the same time, the edge of the two sheet metal tongues 20 facing the cover defines the depth stop of the cover. It is advantageous that the depth stop and the spring element 14 are integrally formed in the closure element 6 in order to exclude manufacturing tolerances. Such tolerances can lead to an undefined adhesion between the spring element 14 and the hook 4.

Das Federelement 14 weist ferner zwei seitliche Blechzungen 32 auf, die außenseitig an der Gehäuseseitenwand 8 neben dem Ausschnitt 20 anliegen (siehe Figuren 4 und den Querschnitt nach Figur 6). Durch diesen Anschlag 32 wird eine definierte Vorspannung des Federelements 14 vorgegeben. Dadurch ist die Kraft, die zum Einrücken des abdeckungsseitigen Hakens 4 in das Verschlusselement 6 notwendig ist, definiert.The spring element 14 also has two lateral sheet metal tongues 32, which rest on the outside of the housing side wall 8 adjacent to the cutout 20 (see FIGS. 4 and the cross section after FIG. 6 ). By this stop 32, a defined bias of the spring element 14 is specified. Thereby, the force necessary for engaging the cover-side hook 4 in the shutter member 6 is defined.

Wie in Figur 5 dargestellt, sind die zurückspringenden Kanten 12 und 18 des Verschlusselements 6 in einem Winkel gegenüber der Seitenwand 8 angeordnet, der etwas größer als 90° ist (auf der von der Abdeckung abgewandten Seite in dem Querschnitt gemäß Figur 5 gemessen). Durch diesen Winkel ist auch ein Ausrücken der Abdeckung 2 möglich. Allerdings ist der Kraftaufwand zum Ausrücken der Abdeckung 2 wesentlich höher als zum Einrücken, weil der Winkel gegenüber der Seitenwand 8 im Vergleich zu den Anlaufschrägen 10 und 16 viel näher an 90° liegt. Durch den Anschlag 32 an der Gehäusewand, welcher die Spannung des Federelements begrenzt, wird ebenfalls die Kraft definiert, welche zum Ein- bzw. Ausrücken des Hakens in bzw. aus dem Federelement 14 notwendig ist.As in FIG. 5 are shown, the recessed edges 12 and 18 of the closure member 6 are arranged at an angle to the side wall 8, which is slightly greater than 90 ° (on the side facing away from the cover in the cross section FIG. 5 measured). Through this angle, a disengagement of the cover 2 is possible. However, the force to disengage the cover 2 is much higher than for engagement, because the angle relative to the side wall 8 compared to the run-on slopes 10 and 16 is much closer to 90 °. By the stop 32 on the housing wall, which limits the tension of the spring element, the force is also defined, which is necessary for engagement or disengagement of the hook in or out of the spring element 14.

Ferner ist der Ausschnitt 20, wie in Figur 4 dargestellt, oberhalb des Federelements 14 so weit gegenüber dessen oberen Rand ausgeschnitten, so dass das Verschlusselement von innen in den Ausschnitt mit den Haken 24 in die Schlitze eingefügt werden kann und nach unten gerückt werden kann. Obgleich das Federelement 14 von außen nach innen durch die Seitenwand beweglich ist, ist es dadurch dennoch möglich, das Verschlusselement 6 nur vom Gehäuseinneren zu montieren. Gemäß einer Ausführungsform ist der Ausschnitt oberhalb des Federelements sogar so groß, dass ein Durchgreifen der Seitenwand 8 von außen möglich ist, um das Federelement 14 an seinem oberen Rand der Anlaufschräge 16 zu ergreifen und nach außen auszulenken. Dadurch kann manuell die Rastverbindung zwischen dem Haken 4 und dem Federelement 14 gelöst werden, um die Abdeckung 2 zu demontieren.Further, the cutout 20 is as in FIG FIG. 4 shown above the spring element 14 so far cut over the upper edge, so that the closure element can be inserted from the inside into the cutout with the hooks 24 in the slots and can be moved down. Although the spring element 14 is movable from outside to inside through the side wall, it is still possible to mount the closure element 6 only from the inside of the housing. According to one embodiment, the cutout is above the Spring element even so large that a passing through the side wall 8 from the outside is possible to take the spring element 14 at its upper edge of the run-on slope 16 and deflect outwards. As a result, the detent connection between the hook 4 and the spring element 14 can be released manually in order to disassemble the cover 2.

Bevorzugt ist eine umlaufende Dichtung 34 an dem Rand der Abdeckung 2 vorgesehen, wobei sich die Dichtung 34 im montierten Zustand der Abdeckung 2 zwischen der Seitenwand 8 und der Abdeckung 2 einfügt. Die Dichtung 34 dichtet den Spalt zwischen der Abdeckung 2 und der Seitenwand 8 ab. Ferner hat die Dichtung den Vorteil, dass sie die Reibungskraft zwischen der Abdeckung 2 und der Seitenwand 8 erhöht. Dadurch wird die Abdeckung nicht nur durch die Federkraft des Verschlusselements 6 gehalten, sondern zusätzlich auch durch die Reibungskraft, welche die Dichtung zwischen dem umlaufenden Rand der Abdeckung 2 und der Gehäuseseitenwand 8 hervorruft.Preferably, a circumferential seal 34 is provided on the edge of the cover 2, wherein the seal 34 in the assembled state of the cover 2 between the side wall 8 and the cover 2 inserts. The seal 34 seals the gap between the cover 2 and the side wall 8. Furthermore, the seal has the advantage that it increases the frictional force between the cover 2 and the side wall 8. As a result, the cover is held not only by the spring force of the closure element 6, but also by the frictional force which causes the seal between the peripheral edge of the cover 2 and the housing side wall 8.

Zahlreiche Modifikationen der vorhergehend beschriebenen bevorzugten Ausführungsform sind im Rahmen der Erfindung möglich, die durch die Ansprüche definiert ist. Insbesondere kann die Geometrie des gehäuseseitigen Verschlusselements geändert sein. Zum Befestigen des Verschlusselements an der Seitenwand sind nicht notwendigerweise vier Haken 22 vorgesehen, sondern das Verschlusselement kann beispielsweise auch mit anderen Befestigungsmitteln (z.B. Nieten oder Schrauben) in der Seitenwand befestigt werden.Numerous modifications of the preferred embodiment described above are possible within the scope of the invention, which is defined by the claims. In particular, the geometry of the housing-side closure element can be changed. Four hooks 22 are not necessarily provided for attaching the closure member to the side wall but, for example, the closure member may also be secured in the side wall by other fasteners (e.g., rivets or screws).

Auch die Form der Abdeckung 2, wie in Figur 1 dargestellt, kann variieren. Beispielsweise lässt sich das Konzept auch auf Wannenleuchten übertragen, welche eine etwa wannenförmige transparente Abdeckung aufweisen.Also the shape of the cover 2, as in FIG. 1 shown, may vary. For example, the concept can also be transferred to trough lamps, which have an approximately trough-shaped transparent cover.
