Description

Die vorliegende Erfindung betrifft ein rahmenartiges Abdeckungselement gemäß dem Oberbegriff des Anspruchs 1, welches zur Abdeckung des Randbereichs einer sogenannten Flächenleuchte vorgesehen ist. Eine entsprechende Leuchte ist beispielsweise aus der DE 10 2004 019 137 A1 bekannt. Auch die WO 2007/130536 A2 offenbart eine Leuchte des Stands der Technik.The present invention relates to a frame-like cover member according to the preamble of claim 1, which is provided for covering the edge region of a so-called surface light. A corresponding lamp is for example from the DE 10 2004 019 137 A1 known. Also the WO 2007/130536 A2 discloses a luminaire of the prior art.

Eine Flächenleuchte weißt in der Regel ein kastenförmiges, üblicherweise rechteckiges Gehäuse auf, welches an einer Seite eine Lichtabstrahlöffnung bildet, über welche flächig Licht abgegeben wird. Diesbezüglich unterscheidet sich die Flächenleuchte von anderen Leuchtenkonstruktionen, bei denen individuell über einzelne Lichtquellen Licht oder Strahler abgegeben wird.A surface light usually knows a box-shaped, usually rectangular housing, which forms a Lichtabstrahlöffnung on one side over which surface light is emitted. In this respect, the surface light differs from other lighting constructions in which light or spotlight is emitted individually via individual light sources.

Innerhalb des kastenförmigen Leuchtengehäuses sind dann Lichtquellen sowie den Lichtquellen zugeordnete Optiken vorgesehen, über welche eine entsprechende Beeinflussung des abgegebenen Lichts vorgenommen wird. Während es in der Vergangenheit üblich war, einige längliche Leuchtstofflampen parallel zueinander anzuordnen, kommen nunmehr vermehrt Lichtquellen auf LED-Basis zum Einsatz. Bei Flächenleuchten werden dabei insbesondere größere LED-Platinen verwendet, auf denen die LEDs matrixartig angeordnet sind. Diese sind dann in der Regel an der Bodenfläche des Gehäuses angeordnet und ggf. durch zusätzliche Maßnahmen vor einer Berührung geschützt, so dass einerseits sogenannte ESD-Schäden an den LEDs vermieden werden und andererseits auch nicht die Gefahr besteht, bei Berühren einen elektrischen Schlag zu erleiden.Within the box-shaped light housing then light sources and the light sources associated optics are provided, via which a corresponding influence of the emitted light is made. While it has been customary in the past to arrange some elongate fluorescent lamps parallel to one another, nowadays LED-based light sources are increasingly being used. In area lights in particular larger LED boards are used, on which the LEDs are arranged like a matrix. These are then usually arranged on the bottom surface of the housing and optionally protected by additional measures against contact, so that on the one hand so-called ESD damage to the LEDs are avoided and on the other hand there is no risk of suffering an electrical shock when touched ,

Aus optischen Gründen weisen derartige Leuchten in der Regel ein rahmenartiges Abdeckungselement auf. Dieses ist an der Seite der Lichtaustrittsöffnung an dem Leuchtengehäuse angeordnet und dient dazu, die eigentliche Lichtaustrittsöffnung, über welche Licht abgegeben wird, rahmenartig zu umschließen. Es handelt sich hierbei in erster Linie um ein Element, durch welches das Erscheinungsbild der Leuchte verbessert wird.For optical reasons, such lights usually have a frame-like cover element. This is arranged on the side of the light exit opening on the lamp housing and serves to surround the actual light exit opening, via which light is emitted, like a frame. It is primarily an element that enhances the appearance of the luminaire.

Je nach Art der in dem Leuchtengehäuse angeordneten Lichtquellen sowie der gewünschten Lichtabgabe sind wie bereits erwähnt innerhalb des Gehäuses optische Elemente angeordnet, über welche das abgegebene Licht beeinflusst wird. Es handelte sich bislang in der Regel um separate Bauelemente, die in entsprechender Weise in dem Gehäuse befestigt wurden.Depending on the type of light sources arranged in the luminaire housing and the desired light output, as already mentioned, optical elements are arranged within the housing, via which the emitted light is influenced. Up to now, these have generally been separate components, which have been fastened in a corresponding manner in the housing.

Von dem vorstehend beschriebenen Stand der Technik ausgehend liegt der vorliegenden Erfindung die Aufgabenstellung zugrunde, eine neuartige Lösung zur Realisierung einer derartigen Flächenleuchte anzugeben, welche hinsichtlich ihres Aufbaus vereinfacht ist.Starting from the above-described prior art, the present invention is the task of specifying a novel solution for the realization of such a surface light, which is simplified in terms of their structure.

Die Aufgabe wird durch ein rahmenartiges Abdeckungselement mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.The object is achieved by a frame-like cover element with the features of claim 1. Advantageous developments of the invention are the subject of the dependent claims.

Das erfindungsgemäße Konzept sieht vor, die beiden Komponenten Abdeckungselement und optisches Element zusammen zu fassen, derart, dass eine einstückige Baueinheit gebildet wird. Es werden hierdurch nicht nur Materialkosten eingespart, da die Herstellung separater Bauteile nicht mehr erforderlich ist, sondern auch der Fertigungsprozess bzw. die Montage der Leuchte wird optimiert, da letztendlich weniger Einzelkomponenten zusammengefügt werden müssen. Weiterhin ist erfindungsgemäß vorgesehen, dass das Abdeckungselement gleichzeitig auch der Lagerung eines flächigen Lichtabgabeelements dient, so dass also durch das Abdeckungselement eine Vielzahl von Funktionen erfüllt werden.The concept according to the invention provides for the two components covering element and optical element to be combined in such a way that a one-piece structural unit is formed. This not only saves material costs, since the production of separate components is no longer necessary, but also the manufacturing process or the assembly of the luminaire is optimized because ultimately fewer individual components must be joined together. Furthermore, the invention provides that the cover element also serves to support a planar light-emitting element, so that a plurality of functions are thus fulfilled by the cover element.

Erfindungsgemäß wird deshalb eine Flächenleuchte mit einem kastenförmigen Leuchtengehäuse, welches an einer Seite eine Lichtaustrittsöffnung aufweist, sowie einem rahmenartigen Abdeckungselement bereitgestellt, wobei das rahmenartige Abdeckungselement einen Rahmenabschnitt und mindestens ein optisches Element aufweist, wobei der Rahmenabschnitt dazu ausgebildet ist, im Bereich der Lichtaustrittsöffnung des Gehäuses an diesem angeordnet zu werden und hierbei rahmenartig einen Lichtabgabebereich der Leuchte zu umfassen,
wobei der Rahmenabschnitt einstückig mit dem mindestens einem sich in den Innenbereich des Leuchtengehäuses erstreckenden optischen Element verbunden ist, welches zur Beeinflussung des von der Leuchte abgegebenen Lichts vorgesehen ist, und wobei es sich bei dem optischen Element um Reflektorwände handelt, welche sich - vorzugsweise geneigt - von dem Rahmenabschnitt zu einer in dem Leuchtengehäuse befindlichen Lichtquelle erstrecken. Ferner weist die Leuchte ein flächiges Lichtabgabeelement auf, wobei der Rahmenabschnitt des Abdeckungselements nach innen ragende Auflageflächen zur Lagerung des Lichtabgabeelements aufweist.According to the invention, therefore, a surface-mounted luminaire is provided with a box-shaped luminaire housing which has a light exit opening on one side and a frame-like cover element, wherein the frame-like cover element has a frame section and at least one optical element, the frame section being designed in the region of the light exit opening of the housing to be arranged on this and thereby frame-like to include a light emitting area of the lamp,
wherein the frame portion is integrally connected to the at least one extending in the inner region of the lamp housing optical element which is provided for influencing the light emitted from the lamp light, and wherein the optical element is reflector walls, which are - preferably inclined - extend from the frame portion to a light source located in the lamp housing. Furthermore, the lamp has a flat light-emitting element, wherein the frame portion of the cover element has inwardly projecting bearing surfaces for supporting the light-emitting element.

Bei dem im Bereich der Lichtaustrittsöffnung des Gehäuses angeordnetenLichtabgabeelement kann es sich beispielsweise um eine Prismenscheibe oder eine um Diffusorscheibe handelnd, wobei wie bereits erwähnt der Rahmenabschnitt nach innen ragende Auflageflächen aufweist und zur Lagerung des flächigen Lichtabgabeelements genutzt wird. Hierdurch wird der Aufbau der Leuchte nochmals weiter optimiert, da die Halterung des transparenten Lichtabgabeelements keine zusätzlichen Maßnahmen erfordert.The light-emitting element arranged in the region of the light exit opening of the housing may, for example, be a prismatic pane or acting around a diffuser disk, wherein, as already mentioned, the frame portion has inwardly projecting bearing surfaces and is used for supporting the flat light-emitting element. As a result, the structure of the lamp is further optimized, since the holder of the transparent light-emitting element requires no additional measures.

Letztendlich wird also eine Leuchte geschaffen, welche hinsichtlich ihrer Möglichkeiten, die Lichtabgabe zu beeinflussen, gleichwertig zu bislang bekannten Lösungen ist, allerdings einen einfacheren und damit kostengünstiger zu realisierenden Aufbau aufweist.Ultimately, therefore, a lamp is created, which is in terms of their ability to influence the light output, equivalent to previously known solutions, but has a simpler and thus less expensive to be realized structure.

Als bevorzugtes Ausführungsbeispiel für die vorliegende Erfindung ist in Fig. 1 eine sogenannte Flächenleuchte 100 dargestellt, bei der LEDs als Lichtquellen zum Einsatz kommen. Die Leuchte 100 weist ein kastenförmiges Leuchtengehäuse 101 auf, an dessen Bodenfläche 102 flächig die LED-Lichtquellen angeordnet sind. Die vier Seitenwände bilden eine rechteckige Lichtabstrahlöffnung 103, über welche Licht abgegeben wird. Hierzu ist im Bereich der Lichtabstrahlöffnung 103 ein flächiges Lichtabstrahlelement angeordnet, dessen Aufbau später noch näher beschrieben wird.As a preferred embodiment of the present invention is in Fig. 1 a so-called area light 100 is shown in which LEDs are used as light sources. The luminaire 100 has a box-shaped luminaire housing 101, on the bottom surface 102 of which the LED light sources are arranged in a planar manner. The four side walls form a rectangular Lichtabstrahlöffnung 103 through which light is emitted. For this purpose, a flat light emitting element is arranged in the region of the light emission opening 103, the structure of which will be described in more detail later.

Als Lichtquellen kommen wie bereits erwähnt LEDs zum Einsatz, die im vorliegenden Fall matrixartig auf mehreren LED-Platinen 110 angeordnet sind, die an der Bodenfläche 102 des Gehäuses 101 positioniert werden. Im dargestellten Ausführungsbeispiel sind die LED-Platinen 110 durch ein flächiges Reflektorelement 111 abgedeckt, sodass die LEDs vor einem versehentlichen Berühren geschützt werden.As already mentioned, LEDs are used as light sources, which in the present case are arranged like a matrix on a plurality of LED boards 110, which are positioned on the bottom surface 102 of the housing 101. In the illustrated embodiment, the LED boards 110 are covered by a flat reflector element 111, so that the LEDs are protected against accidental contact.

Um eine homogene Lichtabgabe zu erzielen ist das transparente Lichtabstrahlelement 120 derart ausgeführt, dass es die Einzelpunkte der LED-Platinen 110 auflöst. Das heißt, das Lichtabstrahlelement 120 weist lichtstreuende oder lichtbeeinflussende Eigenschaften auf, derart, dass die LEDs nicht mehr als individuell leuchtende Punkte erkennbar sind. Zur Vergleichmäßigung der Lichtabgabe trägt ferner bei, dass das Reflektorelement 111 innerhalb des Gehäuses 101 zurück reflektierte Strahlen wiederum reflektiert, so dass Mehrfachreflektionen stattfinden. Gleichzeitig sind Reflektorwände 20 vorgesehen, die sich von den LED-Platinen 110 bis zum Randbereich der Lichtabstrahlöffnung 103 erstrecken. In Fig. 1 ist insbesondere die an der linken Seite des Gehäuses befindliche Reflektorwand 20 erkennbar.In order to achieve a homogeneous light output, the transparent light emitting element 120 is designed such that it dissolves the individual points of the LED boards 110. That is, the light-emitting element 120 has light-diffusing or light-influencing properties, such that the LEDs are no longer recognizable as individually illuminated points. To even out the light output further contributes that the reflector element 111 within the housing 101 back reflected rays reflected again, so that multiple reflections take place. At the same time reflector walls 20 are provided, which extend from the LED boards 110 to the edge region of the Lichtabstrahlöffnung 103. In Fig. 1 In particular, the reflector wall 20 located on the left side of the housing can be seen.

Aus optischen Gründen weist eine Leuchte der dargestellten Art in der Regel auch eine sogenannte rahmenartige Abdeckung auf, welche an dem offenen Endbereich des Gehäuses 101 angeordnet ist. Sie bildet hierbei einen umlaufenden Rahmen, der die Lichtabstrahlöffnung umfasst, sodass die Stirnseiten des Gehäuses 101 für einen Betrachter nicht erkennbar sind.For optical reasons, a lamp of the type shown usually also has a so-called frame-like cover, which is arranged at the open end portion of the housing 101. In this case, it forms a peripheral frame which encompasses the light emission opening so that the front sides of the housing 101 are not recognizable to a viewer.

Bislang handelte es sich bei dem Abdeckungselement 10 sowie den Reflektorwänden 20 um separate Elemente, die bei der Montage der Leuchte 100 in entsprechender Weise an dem Gehäuse 101 zu befestigen waren. Zur Vereinfachung des Leuchtenaufbaus wird nunmehr vorgeschlagen, dass die optischen Elemente, also insbesondere die Reflektorwände 20 Bestandteil der Abdeckung 10 sind. Dieser Erfindungsgedanke kann näher der vergrößerten Schnittdarstellung von Fig. 2 entnommen werden, welche einen seitlichen Endbereich des Leuchtengehäuses 101 zeigt.So far, it was in the cover member 10 and the reflector walls 20 to separate elements that were to be attached during assembly of the lamp 100 in a corresponding manner to the housing 101. In order to simplify the luminaire construction, it is now proposed that the optical elements, that is to say in particular the reflector walls 20, be part of the cover 10. This concept of the invention can be closer to the enlarged sectional view of Fig. 2 are removed, which shows a lateral end portion of the lamp housing 101.

Erkennbar ist hierbei, dass das Rahmenteil 10 derart ausgeführt ist, dass es an der Unterseite des Leuchtengehäuses 101 anliegt, hierbei allerdings sich zusätzlich in Form eines Schrägreflektors 20 in das Leuchteninnere hinein erstreckt, insbesondere bis zur Bodenfläche 102 hin. Es handelt sich hierbei wie bereits erwähnt um ein einstückig ausgebildetes Teil, dessen Bereiche, welche die Reflektorflächen bilden, ggf. noch zusätzlich mit reflektierenden Materialien beschichtet sind.It can be seen here that the frame part 10 is designed such that it rests against the underside of the luminaire housing 101, but in this case additionally extends in the form of an oblique reflector 20 into the luminaire interior, in particular as far as the bottom surface 102. As already mentioned, this is a integrally formed part whose regions which form the reflector surfaces, if necessary, additionally coated with reflective materials.

Die Befestigung der erfindungsgemäßen Abdeckung 10 an dem Leuchtengehäuse 101 erfolgt vorzugsweise dadurch, dass im unteren Teilabschnitt des Reflektorwandbereichs eine Rastöffnung vorgesehen ist, in welche eine in Figur 2 erkennbare Befestigungsfeder 30 eingreift. Diese Befestigungsfeder 30 wird zunächst beispielsweise mit Hilfe einer Schraube an der Gehäuseseitenwand befestigt und ragt leicht in den Innebereich des Leuchtengehäuses 101 hinein. Wird dann die Abdeckung 10 mit den Reflektorwänden 20 von der Unterseite her in das offene Leuchtengehäuse 101 eingeschoben, so greifen die Federn 30 automatisch in die entsprechenden Öffnungen der Reflektorwände 20 und verschnappen mit diesen, derart, dass die Baueinheit Leuchtenabdeckung-Reflektor in einfacher aber effizienter Weise mit dem Gehäuse 101 verrastet wird.The attachment of the cover 10 of the invention to the lamp housing 101 is preferably carried out in that in the lower portion of the reflector wall portion, a detent opening is provided, in which a in FIG. 2 recognizable mounting spring 30 engages. This fixing spring 30 is first attached, for example, by means of a screw on the housing side wall and protrudes easily into the inner region of the lamp housing 101 inside. Then, the cover 10 is inserted with the reflector walls 20 from the bottom into the open luminaire housing 101, the springs 30 automatically engage in the corresponding openings of the reflector walls 20 and snuggle with them, such that the unit luminaire cover reflector in a simple but efficient Way is locked to the housing 101.

Diese Art der Montage wird in dem dargestelltem Ausführungsbeispiel dadurch begünstigt, dass die Reflektorwand 20 leicht geknickt ausgeführt ist, wie dies der Darstellung von Fig. 2 entnommen werden kann. Hierdurch verbleibt im unteren Bereich ein etwas größerer Freiraum zur Anordnung der für die Befestigung erforderlichen Komponenten. Die Reflektorwände 20 selbst erstrecken sich dann schräg nach oben hin möglichst bis in den Randbereich der LED-Platinen 110.This type of assembly is favored in the illustrated embodiment in that the reflector wall 20 is designed to be slightly bent, as shown in the illustration of Fig. 2 can be removed. This leaves in the lower area a slightly larger space for the arrangement of the components required for the attachment. The reflector walls 20 themselves then extend obliquely upward as far as possible into the edge region of the LED boards 110.

Vorzugsweise ist der Rahmenabschnitt der Abdeckung 10 derart ausgeführt, dass nach innen ragende Auflageflächen für das transparente flächige Lichtabstrahlelement 120 gebildet werden. Genau genommen handelt es sich bei dem Lichtabstrahlelement in der Regel nicht um ein einziges flächiges Element sondern um eine Schichtanordnung bestehend aus einer Kunststoffscheibe 121, welche ggf. mit einer Prismatik versehen sein kann, sowie einer darüber angeordneten Streufolie 122 zur Vergleichmäßigung der Lichtabgabe über die gesamte Fläche hinweg. Der Aufbau dieses flächigen Lichtabstrahlelements 120 könnte allerdings je nach gewünschten Lichtabstrahleigenschaften auch anderweitig ausgeführt sein.Preferably, the frame portion of the cover 10 is designed such that inwardly projecting bearing surfaces for the transparent planar Lichtabstrahlelement 120 are formed. Strictly speaking, the light-emitting element is generally not a single planar element but a layer arrangement consisting of a plastic disk 121, which may optionally be provided with a prismatic, and a scattering film 122 arranged above it to even out the light output over the entire Area across. The structure of this flat Lichtabstrahlelements 120 could, however, be carried out otherwise depending on the desired Lichtabstrahleigenschaften.

Wesentlich ist, dass der Rahmenabschnitt der Abdeckung, wie in Fig. 2 erkennbar, derart ausgeführt ist, dass nach innen ragende Vorsprünge 11 gebildet werden, welche sich über die vier Längsseiten der Lichtabstrahlöffnung 103 hinweg erstrecken und dementsprechend zur Auflage des Lichtabstrahlelements 120 genutzt werden können. Diese Auflagebereiche 11 können im Falle einer Ausführung der Abdeckung als Blechteil in einfacher Weise derart gebildet werden, dass der entsprechende Endbereich wie dargestellt nochmals mit einem überstehenden Abschnitt nach innen gebogen ist.It is essential that the frame section of the cover, as in Fig. 2 recognizable, is designed such that inwardly projecting projections 11 are formed, which extend over the four longitudinal sides of the Lichtabstrahlöffnung 103 away and accordingly can be used to support the Lichtabstrahlelements 120. These bearing areas 11 can be formed in the case of an embodiment of the cover as a sheet metal part in a simple manner such that the corresponding End area as shown again bent with a protruding portion inward.

Zur Montage der Leuchte wird dann zunächst das Abstrahlelement 120 in die Abdeckung bzw. auf die Auflageflächen 11 gelegt und dann die sich hierbei ergebende Einheit in das Leuchtengehäuse 101 eingesetzt und mittels der Federn 30 verrastet. Wie dargestellt können dabei die Federn 30 jeweils an ihrer Unterseite einen nach innen ragenden Vorsprung 31 aufweisen, der auf der Oberseite des Abstrahlelements 120 in Anlage kommt. Hierdurch wird dieses Element sicher in der gewünschten Position fixiert, sodass auch ein einfacher Transport der Leuchte 100 ermöglicht ist, ohne das ein Herausfallen des Abstrahlelements 120 zu befürchten ist.For mounting the lamp, the radiating element 120 is then first placed in the cover or on the support surfaces 11 and then the resultant unit is inserted into the lamp housing 101 and latched by means of the springs 30. As shown, the springs 30 may each have on their underside an inwardly projecting projection 31 which comes into contact with the top of the radiating element 120. As a result, this element is securely fixed in the desired position, so that a simple transport of the lamp 100 is made possible without the falling out of the radiating element 120 is to be feared.

Es ist offensichtlich, dass durch die spezielle Ausgestaltung der Abdeckung, welche die Funktionen des Rahmens und der Reflektoren vereinheitlicht, der Aufbau der Leuchte insgesamt und damit insbesondere auch deren Montage vereinfacht wird.It is obvious that the design of the cover, which unifies the functions of the frame and the reflectors, simplifies the construction of the luminaire as a whole, and thus in particular also its assembly, through the special design of the cover.

Eine alternative - nicht erfindungsgemäße - Variante zur Bildung einer Leuchtenabdeckung ist in den Figuren 3 und 4 gezeigt. In diesen Figuren ist ausschließlich die Abdeckung 40 selbst dargestellt, welche wiederum bei einer Leuchte, wie sie in Figur 1 dargestellt ist, zum Einsatz kommen könnte. Die Abdeckung 40 ist also wiederum zunächst dazu vorgesehen, einen unteren Rahmen im Bereich der Lichtaustrittsöffnung der Leuchte zu bilden, gleichzeitig allerdings beinhaltet die Abdeckung 40 eine Optik zur Beeinflussung der Lichtabgabe.An alternative - not according to the invention - variant for forming a lamp cover is in the FIGS. 3 and 4 shown. In these figures, only the cover 40 itself is shown, which in turn in a lamp, as shown in FIG. 1 could be used. The cover 40 is therefore in turn initially provided to form a lower frame in the region of the light exit opening of the lamp, but at the same time the cover 40 includes an optical system for influencing the light output.

Im vorliegenden Ausführungsbeispiel besteht die Optik aus einem sogenannten Zellenraster 45, also aus mehreren, in einer Matrix angeordneten topfförmigen Reflektorzellen 46, welche das Licht zur Unterseite hin jeweils gerichtet abgegeben wird. Die Reflektorzellen 46 sind entsprechend der Darstellung von Fig. 4 pyramidenstumpfartig ausgeführt und weisen an ihrem oberen, schmaleren Ende eine Öffnung 47 zum Lichteintritt sowie an ihrer Unterseite einer Lichtabstrahlöffnung 48 auf. Idealerweise ist jeweils eine Einzelzelle 45 einer einzelnen Lichtquelle zugeordnet.In the present embodiment, the optics consists of a so-called cell grid 45, that is, a plurality of arranged in a matrix cup-shaped reflector cells 46, which is the direction of the light directed towards the bottom respectively. The reflector cells 46 are as shown in FIG Fig. 4 executed truncated pyramidal and have at its upper, narrower end an opening 47 for light entry and on its underside a Lichtabstrahlöffnung 48. Ideally, each individual cell 45 is assigned to a single light source.

Auch im dargestellten zweiten Ausführungsbeispiel erfüllt das Element 40 beide Funktionen, nämlich einerseits eine rahmenförmige Abdeckung zur Verfügung zu stellen und andererseits eine Optik zur Beeinflussung der Lichtabgabe zu bilden. Dabei kann entsprechende Darstellung von Fig. 3 um das Zellenrastersystem 45 herum ein rahmenartiger Abschnitt 41 gesehen sein, über den diffus Licht abgegeben wird.Also in the illustrated second embodiment, the element 40 fulfills both functions, namely on the one hand to provide a frame-shaped cover and on the other hand to form an optical system for influencing the light output. In this case, corresponding representation of Fig. 3 around the cell grid system 45, a frame-like portion 41 can be seen over which diffused light is emitted.

Gleichzeitig kann auch der zentrale Bereich als flächiger Bereich 42 ohne Reflektorzellen ausgeführt sein, wobei dann über diesen Bereich 42 ebenfalls flächig, also beispielsweise diffus oder durch Prismenoptiken gerichtet Licht abgestrahlt wird. Auch in diesem Fall allerdings ist der Aufbau einer entsprechenden Leuchte vereinfacht, da bislang wiederum Abdeckung und Zellenraster separat im Leuchtengehäuse montiert werden mussten.At the same time, the central region can also be designed as a planar region 42 without reflector cells, in which case light is radiated over this region 42 in a planar manner, that is to say, for example, diffusely or by prismatic optics. Even in this case, however, the structure of a corresponding lamp is simplified, since so far in turn cover and cell grid had to be mounted separately in the luminaire housing.

Fig. 5 zeigt schließlich eine dritte Abdeckung 50, welche ebenfalls nicht Gegenstand der Ansprüche ist und in weiten Teilen der Abdeckung der Figuren 3 und 4 ähnelt. Auch hier besteht die Optik, welche durch die Abdeckung 50 gebildet wird, aus einem Zellenrastersystem 55, welches nunmehr allerdings aus zwei parallel zueinander verlaufenden Reflektorreihen 46 besteht. Die Reflektoren sind analog zu dem Ausführungsbeispiel der Figuren 3 und 4 pyramidenstumpfartig ausgebildet. Selbstverständlich könnte allerdings die Form der Reflektorzellen auch anderweitig gewählt werden, wobei gleiches auch für das zweite Ausführungsbeispiel gilt. Beispielsweise sind aus dem Stand der Technik auch rotationsförmige Topfreflektoren oder dergleichen bekannt. Fig. 5 shows finally a third cover 50, which is also not the subject of the claims and in large parts of the cover of FIGS. 3 and 4 similar. Again, the optics, which is formed by the cover 50, from a cell grid system 55, which now consists of two parallel reflector rows 46, however. The reflectors are analogous to the embodiment of FIGS. 3 and 4 formed like a truncated pyramid. Of course, however, the shape of the reflector cells could also be chosen otherwise, the same also applies to the second embodiment. For example, from the prior art, rotationally shaped pot reflectors or the like are known.

Der umlaufende Rahmen 51 der Abdeckung 50 dient wiederum der entsprechenden Abdeckung des Endbereichs des kastenförmigen Leuchtengehäuses. Zu beiden Seiten des Rastersystems 55 werden diffus lichtabgebende Längsflächen 52 gebildet. Auch für dieses Ausführungsbeispiel gilt, dass durch ein einziges Bauteil mehrere Aufgaben einer Flächenleuchte verwirklicht werden.The peripheral frame 51 of the cover 50 in turn serves the corresponding cover of the end portion of the box-shaped lamp housing. Diffuse light-emitting longitudinal surfaces 52 are formed on both sides of the grid system 55. Also applies to this embodiment, that a single component several tasks of a surface lamp can be realized.
