Description

Leuchtenraster mit doppel andigen SeitenreflektorenLuminaire grid with double-sided side reflectors

Die vorliegende Erfindung betrifft ein -Leuchtenraster für eine längliche Leuchte, dessen Seitenreflektoren jeweils eine Innenwand und eine Außenwand aufweisen.The present invention relates to a light grid for an elongated light, the side reflectors of which each have an inner wall and an outer wall.

Bei zur Beleuchtung von Arbeitsbereichen vorgesehenen Leuchten werden oftmals sog. Raster verwendet, um das von der Lichtquelle abgegebene Licht in einen vorgegebenen Abstrahlungsbereich zu lenken und Blendeffekte zu vermeiden. Ein übliches -Leuchtenraster besteht dabei aus zwei länglichen Seitenreflektoren sowie mehreren quer dazu angeordneten Querreflektoren, den sog. Querlamellen. Die Querlamellen sind mit ihren Stirnseiten jeweils an den Seitenreflektoren befestigt, was beispielsweise durch eine Verrastung erfolgt. Hierzu weisen die Seitenreflektoren entsprechende Durchbrüche auf, in welche Teile der Stirnseiten der Lamellen eingreifen.In luminaires intended to illuminate work areas, so-called grids are often used in order to direct the light emitted by the light source into a predetermined radiation area and to avoid glare effects. A common -Light grid consists of two elongated side reflectors and several transverse reflectors arranged transversely to them, the so-called cross blades. The end faces of the transverse slats are each attached to the side reflectors, which is done, for example, by latching. For this purpose, the side reflectors have corresponding openings in which parts of the end faces of the slats engage.

Von der Anmelderin wird eine Leuchte unter der Bezeichnung RTX vertrieben, bei der die Durchbrüche der Seitenreflektoren sowie die Stirnbereiche der darin eingreifenden Querlamellen bewusst sichtbar gehalten sind. Hierdurch wird der Leuchte ein besonderes Aussehen mit einem technischen Charakter verliehen.The applicant sells a luminaire under the name RTX, in which the openings in the side reflectors and the end areas of the transverse lamellae engaging therein are deliberately kept visible. This gives the lamp a special appearance with a technical character.

Auf der anderen Seite gibt es Bestrebungen, -Leuchtenraster mit einer vollständig glatten Außenwand zu bilden. Dies bedeutet allerdings, dass die zur Befestigung der Querlamellen verwendeten Halterungen oder Rastausnehmungen nicht sichtbar sein dürfen. Aus der DE 196 20 209 AI ist daher ein Leuchtenraster bekannt, dessen Seitenreflektoren doppelwandig ausgebildet sind. Hierdurch wird zwischen den beiden Wänden ein Hohlraum gebildet, in den die überstehenden Befestigungslaschen der Querlamellen eingreifen. Da dieser Hohlraum von der Außenwand des Seitenreflektors überdeckt ist, sind die Befestigungslaschen der Querlamellen von außen nicht sichtbar und das -Leuchtenraster besitzt eine vollständig glatte Außenseite.On the other hand, there are efforts to form luminaire grids with a completely smooth outer wall. However, this means that the brackets or locking recesses used to attach the transverse slats must not be visible. From DE 196 20 209 AI a luminaire grid is therefore known, the side reflectors are double-walled. As a result, a cavity is formed between the two walls, in which the protruding fastening tabs of the transverse slats engage. Since this cavity is covered by the outer wall of the side reflector, the fastening tabs of the cross slats are not visible from the outside and the light grid has a completely smooth outside.

Bei dem Leuchtenraster der DE 196 20 209 AI wird ein Seitenreflektor durch zwei separate Teile gebildet, welche die Innen- und Außenwand bilden und an ihren Längsseiten jeweils verrastend ineinander greifen. Eine derartige Struktur ist verhältnismäßig aufwendig und erfordert einen zusätzlichen Arbeitsschritt bei der Montage des Rasters.In the luminaire grid of DE 196 20 209 AI, a side reflector is formed by two separate parts, which form the inner and outer walls and each engage in a latching manner on their long sides. Such a structure is relatively complex and requires an additional step in the assembly of the grid.

Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, ein -Leuchtenraster mit doppelwandigen Seitenreflektoren anzugeben, welches auf einfache Weise zusammengesetzt werden kann. Darüber hinaus soll eine einfache Befestigung des -Leuchtenrasters an der Leuchte ermöglicht werden. Die Aufgabe wird durch ein -Leuchtenraster, welches die Merkmale des Anspruches 1 aufweist, gelöst. Erfindungsgemäß gehen dabei die Innen- und Außenwand eines Seitenreflektors einstückig ineinander über. Ein Seitenreflektor wird somit nicht mehr aus zwei separaten Teilen gebildet, die zusammengesetzt werden müssen. Statt dessen wird ein einzelnes entsprechend geformtes Blechteil verwendet, welches in eine im wesentlichen N-artige Struktur gebracht wird. Hierdurch wird einerseits die Stabilität der Seitenreflektoren erhöht, auf der anderen Seite wird der Aufbau und die Montage des Leuchtenraster vereinfacht.The present invention is therefore based on the object of specifying a light grid with double-walled side reflectors, which can be assembled in a simple manner. In addition, a simple attachment of the light grid to the light is to be made possible. The object is achieved by a light grid which has the features of claim 1. According to the invention, the inner and outer walls of a side reflector merge into one another in one piece. A side reflector is no longer formed from two separate parts that have to be put together. Instead, a single appropriately shaped sheet metal part is used, which is brought into an essentially N-like structure. On the one hand, this increases the stability of the side reflectors, on the other hand, the structure and assembly of the luminaire grid is simplified.

Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche. So befindet sich der einstückige Übergangsbereich - im Querschnitt des Leuchtenrasters gesehen - vorzugsweise an dem der Leuchte gegenüberliegenden Ende der Innen- und Außenwand. Um eine Montage der Querlamellen zu erleichtern, wird ein Seitenreflektor vorzugsweise zunächst in einer Form vorgefertigt, in der die spätere Innen- und Außenwand noch V-förmig auseinander stehen. Hierdurch können die Querlamellen per Handmontage an der Innenwand befestigt werden. Nach der Montage der Querlamellen werden dann die beiden Wände gegeneinander gepreßt, so dass sie an ihren dem Übergangsbereich gegenüberliegenden Enden aneinanderliegende Kantenbereiche bilden. Mit Hilfe eines entsprechend ausgebildeten -Klammerelements, das diese Kantenbereiche übergreift, können die Innen- und Außenwand dann in der entsprechenden Form gehalten werden.Developments of the invention are the subject of the dependent claims. The one-piece transition area - as seen in the cross section of the luminaire grid - is preferably located at the end of the inner and outer wall opposite the luminaire. In order to facilitate assembly of the transverse slats, a side reflector is preferably first prefabricated in a form in which the later inner and outer walls are still V-shaped apart. This allows the cross slats to be attached to the inner wall by hand. After the assembly of the transverse lamellae, the two walls are then pressed against one another so that they form adjacent edge regions at their ends opposite the transition region. The inside and outside walls can then be held in the appropriate shape with the aid of an appropriately designed clamp element that engages over these edge areas.

Eine vorteilhafte Weiterbildung besteht darin, dass das Klammerelement zusätzlich auch Befestigungsmittel aufweist, mit denen das Leuchtenraster an einer Leuchte befestigt werden kann. Vorzugsweise ist das Klammerelement im wesentlichen U-förmig ausgebildet, wobei die Befestigungsmittel durch eine aus der U-förmigen Kontur abstehende Rastnase gebildet werden. Eine besonders bevorzugte Struktur des -Klammerelements besteht darin, dass dieses eine erste Seiten wand aufweist, in der wenigstens eine erste Ausnehmung vorgesehen ist. Ferner weist das -Klammerelement eine zweite Seitenwand auf, die in einem ersten Abschnitt zur ersten Seitenwand hin ausgerichtet und in einem zweiten Abschnitt von der ersten Seitenwand weggebogen ist, wobei im Bereich der Biegekante zwischen dem ersten und dem zweiten Abschnitt wenigstens eine weitere Ausnehmung vorgesehen ist, die einen spitzen Ansatz aufweist, der in Fortsetzung der Ausrichtung des zweiten Abschnitts in den Bereich der ersten Ausnehmung der ersten Seitenwand hineinragt. Vorzugsweise sind jeweils zwei derartige -Klammerelemente vorgesehen, um die Innen- und Außenwand eines Seitenreflektors zusammenzuhalten. Die Befestigung der Querlamellen mit den Innenwänden der Seitenreflektoren erfolgt vorzugsweise durch Verrasten. Dabei können die Querlamellen insbesondere einstückig und im Querschnitt etwa V-förmig ausgebildet sein, wobei an ihren Stirnseiten jeweils Laschen angeformt sind, die nockenartige Vorsprünge aufweisen und in entsprechend geformte Ausnehmungen in den Innenwänden eingreifen. Die Ausnehmungen der Innenwände der Seitenreflektoren haben dann in etwa die Form eines gleichschenkligen Dreiecks, wobei die Ausnehmungen jeweils am Ende der gleichlangen Dreieckschenkel als Schlitz weitergeführt sind und die Oberkanten der Laschen der Querlamellen in diesen Schlitzen passgenau gehalten sind. Alternativ zu den zuvor beschriebenen V- förmig ausgebildeten Querlamellen besteht auch die Möglichkeit, diese aus einem beidseitig gerippten Blechstreifen zu bilden.An advantageous further development consists in the fact that the clamp element additionally also has fastening means with which the light grid can be fastened to a light. The clamp element is preferably essentially U-shaped, the fastening means being formed by a latching lug protruding from the U-shaped contour. A particularly preferred structure of the clamp element is that it has a first side wall in which at least one first recess is provided. Furthermore, the clamp element has a second side wall, which is oriented towards the first side wall in a first section and is bent away from the first side wall in a second section, at least one further recess being provided in the region of the bending edge between the first and the second section , which has a pointed shoulder, which extends into the region of the first recess of the first side wall in continuation of the alignment of the second section. Two such clamp elements are preferably provided in order to hold the inner and outer walls of a side reflector together. The transverse slats are preferably attached to the inner walls of the side reflectors by latching. The transverse lamellae can in particular be made in one piece and approximately V-shaped in cross-section, with tabs being formed on their end faces, which have cam-like projections and engage in correspondingly shaped recesses in the inner walls. The recesses in the inner walls of the side reflectors then have approximately the shape of an isosceles triangle, the recesses each being continued as a slot at the end of the triangle legs of the same length and the upper edges of the tabs of the transverse lamellae being held in these slots with a precise fit. As an alternative to the V-shaped transverse lamellae described above, there is also the possibility of forming them from a sheet metal strip which is ribbed on both sides.

Die vorliegende Erfindung betrifft auch ein Leuchtenraster für eine längliche Leuchte, das aus zwei länglichen Seitenreflektoren sowie mehreren Querlamellen besteht, wobei die Seitenreflektoren jeweils eine Innenwand und eine Außenwand aufweisen und sich das Leuchtenraster durch zumindest ein Klammerelement auszeichnet, welches aneinanderliegende Kantenbereiche der Innen- und Außenwand eines Seitenreflektors übergreift und zusammenhält und ferner Befestigungsmittel zum Befestigen des Leuchtenrasters an einer Leuchte aufweist.The present invention also relates to a luminaire grid for an elongated luminaire, which consists of two elongated side reflectors and a plurality of transverse slats, the side reflectors each having an inner wall and an outer wall and the luminaire grid being characterized by at least one clamp element which adjoining edge regions of the inner and outer walls of a side reflector overlaps and holds together and also has fastening means for fastening the luminaire grid to a luminaire.

Das Grundgerüst des in Fig. 1 dargestellten länglichen -Leuchtenrasters 1 bilden zwei längliche Seitenreflektoren 2, die über eine Reihe von Querlamellen 10 miteinander verbunden sind. An seinen beiden Stirnseiten wird das Raster 1 von zwei Stirnwänden abgeschlossen, auf deren Darstellung allerdings zur besseren Erläuterung der Anordnung der Querlamellen 10 in der vorliegenden Zeichnung verzichtet wurde. Die Seitenreflektoren 2 sind jeweils doppelwandig mit einer Innenwand 3 und einer Außenwand 4 ausgebildet, wobei die Querlamellen 10 mit ihren Stirnbereichen jeweils mit den beiden Innenwänden 3 der Seitenreflektoren 2 verrastet sind. Zwischen einer Innenwand 3 und einer Außenwand 4 eines Seitenreflektors 3 wird ein Hohlraum 6 gebildet, in den die an den Stirnseiten der Querlamellen 10 angeordneten Befestigungslaschen eingreifen.The basic structure of the elongated light grid 1 shown in FIG. 1 is formed by two elongated side reflectors 2, which are connected to one another via a series of transverse slats 10. The grid 1 is made up of two end walls on its two end faces completed, but their representation has been omitted in the present drawing for a better explanation of the arrangement of the transverse lamellae 10. The side reflectors 2 are each double-walled with an inner wall 3 and an outer wall 4, the transverse lamellae 10 being locked with their end regions in each case with the two inner walls 3 of the side reflectors 2. Between an inner wall 3 and an outer wall 4 of a side reflector 3, a cavity 6 is formed, into which the fastening tabs arranged on the end faces of the transverse slats 10 engage.

Das besondere Kennzeichen des erfindungsgemäßen -Leuchtenrasters besteht in der Einstückigkeit der Seitenreflektoren 2. Diese bestehen aus einem einzigen Blechteil, das zu der dargestellten V-förmigen Struktur gebogen wurde. An ihren dem einstückigen Übergang 5 der V-Form gegenüberliegenden Enden weisen die Innen- und Außenwand 3 bzw. 4 jeweils aneinanderliegende Kantenbereiche 3a bzw. 4a auf. Durch ein diese Kantenbereiche 3a, 4a übergreifendes Klammerelement 15 werden die beiden Wände 3 und 4 eines Seitenreflektors 2 in der dargestellten Form gehalten. Die genaue Ausgestaltung des -Klammerelements 15 wird später ausführlich erläutert.The special feature of the light grid according to the invention consists in the one-piece design of the side reflectors 2. These consist of a single sheet metal part which has been bent into the V-shaped structure shown. At their ends opposite the one-piece transition 5 of the V-shape, the inner and outer walls 3 and 4 each have adjacent edge regions 3a and 4a. The two walls 3 and 4 of a side reflector 2 are held in the form shown by a clamp element 15 which overlaps these edge regions 3a, 4a. The exact design of the bracket element 15 will be explained in detail later.

Die Querlamellen sind - im Schnitt - gesehen in bekannter Weise V-förmig ausgestaltet und an ihrer Oberseite durch sog. Umbördelungen geschlossen. Eine entsprechend ausgebildete Querlamelle 10 ist in seitlicher Ansicht in Fig. 3 dargestellt. An ihren beiden Stirnseiten weist sie jeweils zwei Laschen 11 auf, welche zusätzlich mehrere noppenartige Vorsprünge 12 aufweisen. Diese Vorsprünge 12 können durch entsprechende Freistanzungen erhalten werden.As seen in section, the transverse lamellae are designed in a known manner in a V-shape and are closed at the top by so-called flanges. A correspondingly designed transverse lamella 10 is shown in a side view in FIG. 3. It has two tabs 11 on each of its two end faces, which additionally have a plurality of nub-like projections 12. These projections 12 can be obtained by appropriate stampings.

Die zum Verrasten mit den Querlamellen 10 vorgesehenen Ausnehmungen 7 an den Innenwänden 3 der Seitenreflektoren 2 sind in Fig. 2 dargestellt. Die Ausnehmungen7 sind entsprechend der V-Form der Querlamellen - grob gesehen - dreieckförmig mit der Spitze nach unten ausgebildet. An ihrer Oberseite weisen sie jeweils zwei die V-Form fortsetzende Schlitze 8 auf, in welche die an den Stirnseiten der Querlamellen 10 angeordneten Laschen 11 eingreifen. Die Schlitze 8 bilden dabei eine Führung und einen Rückhalt für die Oberseiten der Laschen 11 und haben die Aufgabe, zu verhindern, dass sich die Laschen 11 bei einem entsprechenden Druck nach innen bewegen. Das Verrasten der Querlamellen 10 mit den Seitenwänden 3 wird zusätzlich durch die noppenartigen Vorsprünge 12 verbessert, die sich jeweils hinter die Ausnehmungen 7 in den Innenwänden 3 krallen, wie dies z.B. in Fig. 4 dargestellt ist..The recesses 7 provided on the inner walls 3 of the side reflectors 2 for locking with the transverse slats 10 are shown in FIG. 2. The recesses 7 are roughly triangular in shape with the tip downward in accordance with the V-shape of the transverse lamellae. On their upper side they each have two V-shaped slots 8, into which the tabs 11 arranged on the end faces of the transverse lamellae 10 engage. The slots 8 form a guide and a backing for the upper sides of the tabs 11 and have the task of preventing the tabs 11 from moving inward at a corresponding pressure. The locking of the transverse slats 10 with the side walls 3 is additionally improved by the knob-like projections 12, which each claw behind the recesses 7 in the inner walls 3, as is e.g. is shown in Fig. 4 ..

Die Einteiligkeit der beiden Seitenreflektoren 2 bringt allerdings gewisse Probleme bei der Montage der Querlamellen mit sich. Beim Einstecken der Querlamellen in die dafür vorgesehenen Ausnehmungen ist es nämlich erforderlich, dem Montagedruck der Querlamellen einen entsprechenden Widerstand entgegenzusetzen. Dies ist bei einem doppelwandigen Seitenreflektor insofern schwierig, als der Widerdruck nicht auf das äußere Seitenteil ausgeübt werden kann. Dies hätte nämlich zur Folge, dass sich die Außenwand gegen die Stirnseite der einzusteckenden Querlamelle anlegt und deren Eindringen in die Öffnung der Innenwand verhindert.The one-piece design of the two side reflectors 2, however, brings with it certain problems when installing the transverse slats. When inserting the cross slats in the for it provided recesses, it is namely necessary to provide a corresponding resistance to the mounting pressure of the transverse slats. This is difficult with a double-walled side reflector in that the back pressure cannot be exerted on the outer side part. This would have the consequence that the outer wall bears against the end face of the transverse lamella to be inserted and prevents its penetration into the opening of the inner wall.

Dieses Problem wird bei dem erfindungsgemäßen Leuchtenraster dadurch umgangen, dass die Seitenreflektoren zunächst in einer Form vorgefertigt werden, in der sie noch V-förmig mit einem verhältnismäßig großen Öffnungswinkel auseinanderstehen. Eine derartige Struktur ist in Fig. 5a dargestellt. Die Innenwand 3 und Außenwand 4 stehen dabei mit einem Winkel von zumindest 30° auseinander. Hierdurch besteht die Möglichkeit, bei einer Handmontage der Querlamellen auch auf die entsprechende Innenseite der Innenwand 3 den Gegendruck auszuüben, bis die Querlamelle in ihre Öffnung in der Innenwand 3 eingerastet ist. Auf diese Weise werden zunächst alle Querlamellen nacheinander montiert. Wenn die Montage abgeschlossen ist, werden die noch V-förmig auseinanderstehenden Seitenwände 3 und 4 durch Druck auf den Scheitel 5 mittels einer entsprechenden Vorrichtung gegeneinander gepresst, bis die Oberkanten 3a bzw. 4a der Innen- und Außenwand 3 bzw. 4 aneinanderliegen und sich die in den Figuren 5b und 5c dargestellte Struktur ergibt.This problem is avoided in the luminaire grid according to the invention in that the side reflectors are first prefabricated in a form in which they are still V-shaped with a relatively large opening angle. Such a structure is shown in Fig. 5a. The inner wall 3 and outer wall 4 are at an angle of at least 30 ° apart. This makes it possible to apply the counterpressure to the corresponding inner side of the inner wall 3 when the transverse slats are assembled by hand until the transverse slat is locked into its opening in the inner wall 3. In this way, all cross blades are assembled one after the other. When the assembly is complete, the side walls 3 and 4, which are still V-shaped apart, are pressed against one another by pressure on the apex 5 by means of a corresponding device until the upper edges 3a and 4a of the inner and outer walls 3 and 4 abut one another and the structure shown in Figures 5b and 5c.

Da nach wie vor eine bestimmte Restelastizität besteht, welche versucht, die beiden Seitenwände 3 und 4wieder auseinander zu drücken, wird auf die aneinanderliegenden Kantenbereiche 3a, 4a ein Klammerelement 15 aufgesetzt. Dieses Klammerelement 15, dessen Struktur nachfolgend erläutert werden soll, hält die beiden Seitenwände 3 und 4 bleibend aneinander.Since there is still a certain residual elasticity that tries to push the two side walls 3 and 4 apart again, a clamp element 15 is placed on the adjacent edge regions 3a, 4a. This clamp element 15, the structure of which will be explained below, holds the two side walls 3 and 4 against one another permanently.

Das in den Fig. 6 bis 9 dargestellte Klammerelement ist im Schnitt U- oder haarnadelförmig ausgebildet. Es weist zunächst eine erste gerade Seitenwand 16 mit zwei ersten Ausnehmungen 16a auf. Die gegenüberliegende zweite Seitenwand 17 ist in einen ersten Abschnitt 17a, der zur ersten Seitenwand 16 hin ausgerichtet ist, und einen zweiten Abschnitt 17b, der von der ersten Seitenwand 16 weggebogen ist, unterteilt. Zwischen dem ersten Abschnitt 17a und dem zweiten Abschnitt 17b wird somit eine Biegekante 17e gebildet. Ferner sind im Bereich der Biegekante 17e zwei weitere Ausnehmungen vorgesehen, die jeweils einen spitzen Ansatz 17d aufweisen, der in Fortsetzung der Ausrichtung des zweiten Abschnitts 17b in den Bereich der ersten Ausnehmung 16a der ersten Seitenwand 16 hineinragt. Die beiden Ansätze 17d bewirken somit in Zusammenwirkung mit der Biegekante 17e und der ersten Seitenwand 16 einen Klemmsitz des Klammerelements 15 auf den beiden Oberkanten 3a, 4b der Seitenwände 3,4 des Seitenreflektors, wie dies in den Figuren 5b und 5c dargestellt ist.The clip element shown in FIGS. 6 to 9 is U-shaped or hairpin-shaped in section. It initially has a first straight side wall 16 with two first recesses 16a. The opposing second side wall 17 is divided into a first section 17a, which is oriented towards the first side wall 16, and a second section 17b, which is bent away from the first side wall 16. A bending edge 17e is thus formed between the first section 17a and the second section 17b. Furthermore, two further recesses are provided in the region of the bending edge 17e, each of which has a pointed shoulder 17d which, as the second section 17b continues, projects into the region of the first recess 16a of the first side wall 16. The two projections 17d thus, in cooperation with the bending edge 17e and the first side wall 16, cause the clamping element 15 to be clamped on the two upper edges 3a, 4b of the side walls 3, 4 of the side reflector, as shown in FIGS. 5b and 5c.

Im Verbindungsbereich zwischen der ersten Seitenwand 16 und der zweiten Seitenwand 17 ist femer eine Freistanzung vorhanden, durch eine aus der U-förmigen Kontur des Klammerelements abstehende Rastnase 17c in Form eines geraden Vorsprungs gebildet wird. Wie nachfolgend erläutert wird, dient diese Rastnase 17c zur Befestigung des -Leuchtenrasters 1 an einem -Leuchtengehäuse. Alterantiv zu der dargestellten Struktur kann die Rastnase 17c an ihrem vorderen Ende auch zurückgebogen und somit gekrümmt ausgebildet sein. Wesentlich ist, dass das Klammerelement 15 aus einem Material besteht, das dauerhaft federnd ist und einen hohen Verformungswiderstand aufweist, so dass eine sichere Befestigung des Rasters an dem -Leuchtengehäuse gewährleistet ist.In the connection area between the first side wall 16 and the second side wall 17 there is also a cut-out, by means of which a latching nose 17c projecting from the U-shaped contour of the clamp element is formed in the form of a straight projection. As will be explained in the following, this latching nose 17c serves for fastening the light grid 1 to a light housing. As an alternative to the structure shown, the detent 17c can also be bent back at its front end and thus be curved. It is essential that the clamp element 15 is made of a material that is permanently resilient and has a high resistance to deformation, so that a secure attachment of the grid to the lamp housing is ensured.

Fig. 10 zeigt schließlich die Befestigung des erfindungsgemäßen -Leuchtenrasters 1 an einem -Leuchtengehäuse 20. Dieses weist eine nach unten geöffnete C-Form auf und kann beispielsweise durch eine Tragschiene eines Stromschienensystems gebildet werden. Im Inneren des Gehäuses 20, das im wesentlichen aus zwei Seitenwänden 21 sowie einer Boden wand 22 gebildet wird, sind die elektronischen Komponenten der Leuchte, beispielsweise ein elektronisches Vorschaltgerät 26 sowie entsprechende Leiterdrähte 28, die in einem Stromleitprofil 27 verlaufen, angeordnet. Die Befestigung der Lampenfassung 24 erfolgt mit Hilfe von zwei Klemmstegen 25, die mit entsprechenden Vorsprüngen 23 an den Innenseiten der Seitenwände 21 verrasten. In ihrem unteren Bereich weisen die beiden Seitenwände 21 des Leuchtengehäuses 20 femer jeweils eine längliche Ausnehmung 22 auf, in welche die Rastnasen 17c der -Klammerelemente 15 eingreifen können. Das fertig montierte Leuchtenraster 1 kann somit auf einfache Weise an die Unterseite des -Leuchtengehäuses 20 angeklemmt werden.10 finally shows the fastening of the light grid 1 according to the invention to a light housing 20. This has a C-shape which is open at the bottom and can be formed, for example, by a mounting rail of a busbar system. Inside the housing 20, which is essentially formed from two side walls 21 and a bottom wall 22, the electronic components of the lamp, for example an electronic ballast 26 and corresponding conductor wires 28 which run in a current conducting profile 27, are arranged. The lamp holder 24 is fastened with the aid of two clamping webs 25 which engage with corresponding projections 23 on the inner sides of the side walls 21. In its lower region, the two side walls 21 of the lamp housing 20 each further have an elongated recess 22, into which the latching lugs 17c of the clamp elements 15 can engage. The fully assembled lamp grid 1 can thus be easily clamped to the underside of the lamp housing 20.

Durch die vorliegende Erfindung wird somit ein Leuchtenraster angegeben, welches durch die doppelwandige Ausgestaltung der Seitenreflektoren eine glatte Außenfläche aufweist. Das erfindungsgemäße Raster zeichnet sich dabei insbesondere durch seinen einfachen und kostengünstigen Aufbau aus, wobei zusätzlich die Möglichkeit gegeben ist, das Raster auf einfache Weise an einer Leuchte zu befestigen. The present invention thus provides a luminaire grid which has a smooth outer surface due to the double-walled design of the side reflectors. The grid according to the invention is characterized in particular by its simple and inexpensive structure, it also being possible to simply fasten the grid to a lamp.
