Description

Leuchte mit Raster zur Lichtabgabe Luminaire with grid for light emission
Die vorliegende Erfindung betrifft eine Leuchte gemäß dem Oberbegriff des Anspruchs 1, welche ein sog. Zellenraster zur Abgabe des von einer Lichtquelle der Leuchte abgegebenen Lichts aufweist.The present invention relates to a luminaire according to the preamble of claim 1, which has a so-called cell grid for emitting the light emitted by a light source of the luminaire.
Ausgangspunkt für die vorliegende Erfindung ist eine Rasterleuchte, wie sie bspw. aus der WO 2004/094897 Al der Anmelderin bekannt ist. Hierbei ist in einem länglichen Leuchtengehäuse eine Lichtquelle - bspw. in Form einer Leuchtstoffröhre - angeordnet, wobei in Abstrahlrichtung gesehen vor der Lichtquelle ein sog. Leuchtenraster angeordnet ist. Dieses weist vor der Lichtquelle befindliche, in Längsrichtung hintereinander angeordnete Durchtrittsöffnungen auf, durch welche das Licht der Lichtquelle abgestrahlt wird. An diese Durchtrittsöffnungen schließen sich bei dieser bekannten Leuchte ferner Topfreflektoren an. Diese dienen einerseits dazu, das von der Lichtquelle abgegebene Licht innerhalb eines bestimmten Winkelbereichs abzustrahlen, der derart bemessen ist, dass für einen unterhalb der Leuchte befindlichen Betrachter keine Blendeffekte auftreten, auf der anderen Seite vermitteln die Topfreflektoren den Eindruck, als würde die Leuchte eine Vielzahl einzelner Strahler aufweisen. Dieser optische Effekt ist äußerst ansprechend und wird hier mit verhältnismäßig einfachen Mitteln erzielt.The starting point for the present invention is a grid lamp, as it is known, for example, from WO 2004/094897 A1 of the Applicant. In this case, a light source is arranged in an elongated luminaire housing, for example in the form of a fluorescent tube, a so-called luminous grid being arranged in the emission direction in front of the light source. This has located in front of the light source, in the longitudinal direction successively arranged passage openings through which the light of the light source is radiated. At these passages close in this known lamp also pot reflectors. These serve on the one hand to emit the light emitted by the light source within a certain angular range, which is dimensioned such that no glare effects occur for a viewer located below the lamp, on the other hand, the pot reflectors give the impression as if the lamp a variety have single radiator. This optical effect is extremely appealing and is achieved here with relatively simple means.
Die Abgabe des Lichts über das zuvor beschriebene Raster in einen bestimmten Winkelbereich bewirkt, dass ein direkter Blick auf die Lichtquelle der Leuchte nur dann möglich ist, wenn sich ein Betrachter nahezu direkt unterhalb der Leuchte befindet. In diesem Fall werden Personen, die sich innerhalb des Raums befinden, in dem die Leuchte positioniert ist, in der Regel nicht geblendet. Ferner werden hierdurch auch ungewünschte Reflektionen an Bildschirmarbeitsplätzen vermieden, weshalb sich derartige Leuchten insbesondere zum Einsatz in Büro- oder an sonstigen Arbeitsplätzen eignen.The emission of light over the grid described above in a certain angular range causes a direct view of the light source of the lamp is only possible when a viewer is almost directly below the lamp. In this case, people who are inside the room where the luminaire is positioned are usually not blinded. Furthermore, this also unwanted reflections are avoided at VDU workstations, which is why such lights are particularly suitable for use in office or other workplaces.
Eine Problematik einer auf einen sehr engen Winkelbereich eingeschränkten Lichtabgabe besteht allerdings darin, dass für einen Betrachter oftmals nur schwer erkennbar ist, ob eine Leuchte tatsächlich eingeschaltet ist oder nicht. Ferner wäre es oftmals wünschenswert, auch den oberhalb oder seitlich einer Leuchte befindlichen Bereich zumindest geringfügig aufzuhellen, um insgesamt gesehen die Ausleuchtung eines Raums zu verbessern. Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, die aus der WO 2004/094897 Al bekannte Leuchte derart weiter zu entwickeln, dass deren Aussehen zusätzlich verbessert wird und ferner optimierte lichttechnische Eigenschaften erzielt werden.One problem with a light output limited to a very narrow angular range, however, is that it is often difficult for a viewer to see whether a luminaire is actually switched on or not. Furthermore, it would often be desirable to at least slightly lighten the area above or to the side of a luminaire, in order to improve the overall illumination of a room. Therefore, the object of the present invention is to further develop the luminaire known from WO 2004/094897 A1 in such a way that its appearance is additionally improved and, furthermore, optimized photometric properties are achieved.
Die Aufgabe wird durch eine Leuchte, welche die Merkmale des Anspruchs 1 aufweist, gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.The object is achieved by a luminaire having the features of claim 1. Advantageous developments of the invention are the subject of the dependent claims.
Die erfindungsgemäße Lösung beruht auf dem Gedanken, eine Rasterleuchte derart auszugestalten, dass auch über die Seitenbereiche der Leuchte Licht abgegeben wird, wobei allerdings dieses Licht derart ist, dass die einschlägigen Normen bezüglich Blendung sowohl hinsichtlich des seitlich abgestrahlten Lichts als auch hinsichtlich des über das Leuchtenraster abgestrahlten Lichts eingehalten werden. Hierzu ist vorgesehen, dass das Leuchtenraster mit einer reflektierenden Beschichtung versehen ist, welche für einen Teil des von der Lampe abgegebenen Lichts durchlässig ist. Ferner sind zu beiden Seiten des Leuchtenrasters Profilelemente angeordnet, welche Gehäusewände der Leuchte bilden und erfindungsgemäß aus einem transparenten Material bestehen.The solution according to the invention is based on the idea of designing a grid lamp in such a way that light is emitted via the side areas of the lamp, although this light is such that the relevant standards with respect to glare both with respect to the laterally emitted light and with respect to the luminaire grid be emitted radiated light. For this purpose, it is provided that the luminaire grid is provided with a reflective coating which is permeable to a part of the light emitted by the lamp. Furthermore, profile elements are arranged on both sides of the lighting grid, which form housing walls of the lamp and according to the invention consist of a transparent material.
Erfindungsgemäß wird dementsprechend eine Leuchte mit Mitteln zum Halten und zum elektrischen Anschließen wenigstens einer rohrförmigen Lampe, einem - in Abstrahlrichtung gesehen - vor der Lampe angeordneten Leuchtenraster, welches mehrere zur Lichtabstrahlung vorgesehene Durchtrittsöffnungen aufweist, sowie zu beiden Seiten des Leuchtenrasters angeordneten und Gehäusewände bildenden Profilelementen vorgeschlagen, wobei erfindungsgemäß das Leuchtenraster mit einer reflektierenden Beschichtung versehen ist, welche für einen Teil des von der Lampe abgegebenen Lichts durchlässig ist, und wobei ferner die Profilelemente aus einem transparenten Material bestehen. Vorzugsweise ist die Beschichtung desAccording to the invention, accordingly, a luminaire is provided with means for holding and electrically connecting at least one tubular lamp, a luminaire grid arranged in front of the lamp, which has a plurality of passage openings provided for light emission, and profile elements arranged on both sides of the luminaire grid and forming housing walls , wherein according to the invention the luminaire grid is provided with a reflective coating, which is permeable to a part of the light emitted by the lamp, and further wherein the profile elements consist of a transparent material. Preferably, the coating of the
Leuchtenrasters derart ausgestaltet, dass dieses eine Durchlässigkeit für das von der Lampe abgegebene Licht in einem Bereich von etwa 2 - 10 %, besonders bevorzugt in einem Bereich von etwa 2 - 6 % aufweist.Luminaire raster designed such that this has a permeability to the light emitted by the lamp light in a range of about 2-10%, more preferably in a range of about 2-6%.
Dadurch, dass erfindungsgemäß nunmehr auch eine Lichtabgabe zur Seite hin ermöglicht ist, wird erzielt, dass auch die Leuchte umgebende Wand- und/oder Deckenbereiche aufgehellt werden können. Da allerdings die Menge des seitlich abgegebenen Lichts begrenzt ist, wird vermieden, dass Blendeffekte für einen Betrachter auftreten. Die teildurchlässige Ausgestaltung des Leuchtenrasters sowie die Transparenz der Profilelemente rühren ferner dazu, dass die innerhalb des Gehäuses der Leuchte befindlichen Komponenten für einen Beobachter teilweise sichtbar werden. Dies führt insbesondere dann zu besonders optisch ansprechenden Effekten, wenn dasThe fact that according to the invention now also a light output is made possible to the side, it is achieved that the wall and / or ceiling areas surrounding the lamp can be brightened. However, since the amount of light emitted from the side is limited, glare effects are avoided for a viewer. The partially transparent design of the luminaire grid and the transparency of the profile elements also result in the components located within the housing of the luminaire being partially visible to an observer. This leads in particular to particularly visually appealing effects, if the
Leuchtenraster wie aus der WO 2004/094897 Al bekannt ausgestaltet ist. Gemäß einer bevorzugten Weiterbildung der vorliegenden Erfindung ist dementsprechend das Leuchtenraster durch mehrere in Längsrichtung hintereinander angeordnete Rasterelemente gebildet. Ein Rasterelement weist dabei jeweils einen sich in Längsrichtung erstreckenden Rückreflektor auf, der dazu bestimmt ist, einen Teil des von der Lampe abgegebenen Lichts entgegen der Abstrahlrichtung zu reflektieren, wobei in dem Rückreflektor die Durchtrittsöffnungen angeordnet sind. An diese Durchtrittsöffhungen schließen sich dann in Abstrahlrichtung Topfreflektoren an, die jeweils einzelne Zellen des Zellenrasters bilden und welche vorzugsweise mit dem Rückreflektor einstückig verbunden sind. Die Topfreflektoren können ferner an ihren Randbereichen über eine parallel zur Lichtquelle ausgerichtete Verbindungsplatte miteinander verbunden sein. Sie können bspw. eine kreisförmige, eine quadratische oder eine rechteckige Lichtaustrittsöffnung aufweisen. Der vorzugsweise im Querschnitt etwa halbkreisförmig ausgestaltete Rückreflektor ist dabei derart ausgebildet, dass er die Lampe seitlich zumindest teilweise umgreift.Luminaire grid as known from WO 2004/094897 Al configured configured. According to a preferred embodiment of the present invention, the luminaire grid is accordingly formed by a plurality of raster elements arranged one behind the other in the longitudinal direction. In this case, a raster element in each case has a rear reflector which extends in the longitudinal direction and is intended to reflect part of the light emitted by the lamp counter to the emission direction, wherein the passage openings are arranged in the back reflector. To this Durchtrittsöffhungen then close in the direction of radiation pot reflectors, which each form individual cells of the cell grid and which are preferably integrally connected to the rear reflector. The pot reflectors may also be connected to each other at their edge regions via a connecting plate aligned parallel to the light source. You can, for example, have a circular, a square or a rectangular light exit opening. The preferably in cross-section approximately semicircular configured back reflector is designed such that it laterally surrounds the lamp at least partially.
Andere Weiterbildungen der Erfindung betreffen Möglichkeiten, die verschiedenen Komponenten der erfindungsgemäßen Leuchte in besonders effektiver Weise zusammenzufügen. Hierzu können gemäß einem bevorzugten Ausführungsbeispiel Halteelemente vorgesehen sein, die einerseits das Leuchtenraster sowie andererseits die Profilelemente halten. Diese Halteelemente können wiederum durch zu beiden Seiten der Lampe angeordnete Profilkörper gebildet sein, wobei diese dann mit dem Leuchtenraster und den Profilelementen über Steck- und/oder Rastverbindungen verbunden sind. Ferner können die Halteelemente mit Aufhängungsmitteln zum Aufhängen der Leuchte verbunden sein, so dass also in verhältnismäßig einfacher Weise eine stabile Leuchtenkonstruktion geschaffen wird.Other developments of the invention relate to possibilities to assemble the various components of the luminaire according to the invention in a particularly effective manner. For this purpose, according to a preferred embodiment, holding elements can be provided which, on the one hand, hold the luminaire grid and, on the other hand, the profile elements. These holding elements can in turn be formed by arranged on both sides of the lamp profile body, which are then connected to the luminaire grid and the profile elements via plug and / or snap-in connections. Furthermore, the holding elements can be connected to suspension means for hanging the lamp, so that therefore a stable lighting construction is provided in a relatively simple manner.
Die Profilelemente sind vorzugsweise aus Kunststoff ausgebildet und können unterschiedlich profiliert sein, so dass die Außenform der Leuchte in einfacher Weise speziellen Wünschen angepasst werden kann.The profile elements are preferably formed of plastic and can be profiled differently, so that the outer shape of the lamp can be easily adapted to specific needs.

Leuchte.Lamp.
Die in den Fig. 1 bis 6 dargestellte und allgemein mit dem Bezugszeichen 1 versehene erfindungsgemäße Leuchte ist im dargestellten Ausfuhrungsbeispiel als Hängeleuchte ausgebildet und wird dementsprechend mittels einer Seilaufhängung 41 an einer nicht näher dargestellten Decke befestigt. Das langgestreckte Gehäuse 2 dient der Aufnahme einer Lichtquelle 3 sowie entsprechender Lampenbetriebsgeräte zum Ansteuern der Lichtquelle 3. Im dargestellten Ausfuhrungsbeispiel ist das Lampenbetriebsgerät, welches bspw. als sog. elektronisches Vorschaltgerät ausgebildet sein kann, in einem Endbereich 4 des länglichen Gehäuses 2 angeordnet. In diesem Bereich findet keine Lichtabgabe statt, wobei selbstverständlich auch eine andere Positionierung des bzw. der Lampenbetriebsgeräte denkbar wäre. An den Endbereich 4 schließt sich dann der Bereich mit der Lichtquelle 3 an, die im dargestellten Ausfuhrungsbeispiel durch eine Leuchtstoffröhre gebildet ist. Selbstverständlich wäre auch die parallele Anordnung von mehreren Leuchtstoffröhren denkbar, um die Lichtabgabe zu erhöhen.The illustrated in FIGS. 1 to 6 and generally provided with the reference numeral 1 inventive lamp is formed in the illustrated embodiment as a pendant light and is accordingly secured by means of a cable suspension 41 to a ceiling, not shown. The elongated housing 2 serves to receive a light source 3 and corresponding lamp operating devices for driving the light source 3. In the illustrated embodiment, the lamp operating device, which may be formed, for example. As so-called. Electronic ballast, arranged in an end portion 4 of the elongated housing 2. In this area, no light emission takes place, which of course also a different positioning of the or the lamp operating devices would be conceivable. At the end region 4, then the area with the light source 3 connects, which is formed in the illustrated embodiment by a fluorescent tube. Of course, the parallel arrangement of several fluorescent tubes would be conceivable to increase the light output.
Das von der Lichtquelle 3 abgegebene Licht wird - wie später noch ausführlich erläutert — im Wesentlichen über den gesamten Umfang der Leuchte 1 hinweg abgegeben. Hauptabstrahlrichtung ist jedoch zur Unterseite hin, da die Leuchte 1 zur Ausleuchtung von Arbeitsplätzen oder entsprechenden Räumen vorgesehen ist.The light emitted by the light source 3 is - as explained in more detail later - discharged substantially over the entire circumference of the lamp 1 away. However, the main emission direction is towards the bottom, since the luminaire 1 is intended for illumination of workplaces or corresponding rooms.
Die Lichtabgabe zur Unterseite hin erfolgt insbesondere über ein Leuchtenraster 5. Dieses ist im dargestellten Ausführungsbeispiel als Zellenraster ausgebildet, d.h. das Licht wird über einzelne Öffnungen abgegeben, so dass insgesamt der Eindruck erweckt wird, als wären einzelne Strahler hintereinander über die Länge der Leuchte 1 hinweg angeordnet. Dies ist insbesondere der Darstellung der Unterseite in Fig. 6 entnehmbar, in der gezeigt ist, dass die Leuchtstofflampe 3 jeweils nur über einen kurzen Abschnitt erkennbar ist. Entsprechend der Darstellung in Fig. 4 wiederum ist das Gehäuse 2 der Leuchte 1 zur Oberseite hin offen, d.h. auch eine Indirektbeleuchtung wird ermöglicht, in dem ein Teil des Lichts an die Decke geworfen wird.This is in the illustrated embodiment, designed as a cell grid, ie the light is emitted through individual openings, so that the overall impression is created as if individual radiators in a row over the length of the lamp 1 away arranged. This is in particular the representation of the underside in Fig. 6 can be removed, in which it is shown that the fluorescent lamp 3 in each case only one short section is recognizable. According to the illustration in FIG. 4, the housing 2 of the luminaire 1 is again open towards the top side, ie an indirect illumination is also made possible in which a part of the light is thrown to the ceiling.
Neben dieser Direkt-/ Indirektbeleuchtung ist erfindungsgemäß auch vorgesehen, dass über die Seitenwände des Gehäuses 2 eine Lichtabgabe erfolgt. Hierzu sind die verschiedenen Komponenten der Leuchte 1 speziell ausgebildet, was nachfolgend näher anhand der Fig. 7 bis 9 erläutert werden soll. Die Fig. 7 und 8 zeigen dabei jeweils die Einzelteile der erfindungsgemäßen Leuchte 1, während hingegen Fig. 9 eine Schnittdarstellung der Leuchte 1 im zusammengesetzten Zustand zeigt.In addition to this direct / indirect lighting, it is also provided according to the invention that light is emitted via the side walls of the housing 2. For this purpose, the various components of the lamp 1 are specially designed, which will be explained in more detail below with reference to FIGS. 7 to 9. FIGS. 7 and 8 show the individual parts of the lamp 1 according to the invention, while FIG. 9 shows a sectional view of the lamp 1 in the assembled state.
Zentrales Element der Leuchte 1 für die Lichtabgabe ist zunächst das bereits angesprochene Leuchtenraster 5, welches genau genommen als sog. Zellenraster ausgebildet ist. Dieses wird gemäß einem besonders bevorzugten Ausführungsbeispiel durch mehrere sog. Rasterelemente 10 gebildet, welche in Längsrichtung der Leuchte hintereinander angeordnet sind und dementsprechend in ihrer Gesamtheit das Leuchtenraster 5 bilden. Derartige Rasterelemente 10 sind bspw. aus der oben erwähnten WO 2004/094897 Al bekannt.The central element of the luminaire 1 for the light emission is initially the already mentioned luminaire grid 5, which, strictly speaking, is designed as a so-called cell grid. This is formed according to a particularly preferred embodiment by a plurality of so-called. Raster elements 10, which are arranged one behind the other in the longitudinal direction of the luminaire and accordingly form the luminaire grid 5 in their entirety. Such raster elements 10 are known, for example, from the above-mentioned WO 2004/094897 A1.
Ein Rasterelement 10 weist dabei zunächst einen im Querschnitt gesehen etwa halbkreisförmigen Rückreflektor 11 auf, der - wie Fig. 9 entnommen werden kann - die Lampe 3 seitlich sowie an der Unterseite umgibt. In Lichtabstrahlrichtung gesehen sind in diesem Rückreflektor 1 1 in regelmäßigen Abständen die sog. Durchtrittsöffnungen 12 vorgesehen, über die das Licht abgegeben wird. An diese Durchtrittsöffnungen 12 schließen sich topfartig ausgestaltete Reflektoren 13 an, die die einzelnen Zellen des Rasters bilden und jeweils den Eindruck eines einzelnen Strahlers erwecken sollen. Die Öffnungen dieser Topfreflektoren 13 schließen jeweils bündig mit einer gemeinsamen Verbindungsplatte 14 ab, welche die Unterseite des Rasterelements 10 bildet. Durch diese Platte 14 sind außerdem zu beiden Seiten der Topfreflektoren 13 vorstehende Vorsprünge bzw. Leisten 15 gebildet. Zur Ausgestaltung dieser Rasterelemente 10 wird ergänzend auch auf die zuvor genannte WO 2004/094897 Al verwiesen. Sie werden vorzugsweise durch Spritzgußteile gebildet und sind dementsprechend jeweils einstückig ausgebildet.In this case, a grid element 10 initially has an approximately semicircular rear reflector 11, seen in cross-section, which - as can be seen in FIG. 9 - surrounds the lamp 3 laterally as well as on the underside. Seen in light emission direction, the so-called. Passage openings 12 are provided in this rear reflector 1 1 at regular intervals, through which the light is emitted. At these passages 12 close cupped designed reflectors 13, which form the individual cells of the grid and should give the impression of a single spotlight. The openings of these pot reflectors 13 each terminate flush with a common connecting plate 14, which forms the underside of the grid element 10. By this plate 14 13 protruding projections or strips 15 are also formed on both sides of the pot reflectors. For the design of these raster elements 10, reference is additionally made to the aforementioned WO 2004/094897 Al. They are preferably formed by injection molded parts and are accordingly each formed in one piece.
Die Halterung der Rasterelemente 10 erfolgt mit Hilfe zweier Profilteile 20, welche vorzugsweise aus länglichen Aluminiumteilen gebildet sind und die zentralen Halteelemente der Leuchte 1 darstellen. Die Ausgestaltung dieser Profilteile 20 kann insbesondere der Darstellung in Fig. 8 entnommen werden. Hierbei ist zunächst erkennbar, dass diese eine in Längsrichtung verlaufende erste Ausnehmung 21 aufweisen, welche hinsichtlich ihrer Form der Kontur der Außenseiten des Rückretlektors 1 1 entspricht. Der Rückreflektor 1 1 kann also in diese Ausnehmungen 21 eingreifen, wodurch in einfacher Weise die hintereinander angeordneten Rasterelemente 10 zu einem länglichen Leuchtenraster zusammengefügt werden können.The holder of the grid elements 10 takes place with the aid of two profile parts 20, which are preferably formed of elongated aluminum parts and represent the central holding elements of the lamp 1. The configuration of these profile parts 20 can be seen in particular in the illustration in FIG. 8. This is first recognizable that they have a longitudinally extending first recess 21, which corresponds in shape to the contour of the outer sides of the Rückretlektors 1 1. The back reflector 1 1 can thus engage in these recesses 21, which can be joined together to form an elongated luminaire grid in a simple manner, the successively arranged grid elements 10.
Des Weiteren weisen die Halteelemente 20 seitlich vorstehende Arme 22 auf, welche - wie später noch erläutert - zur Halterung der seitlichen Profilelemente eingesetzt werden. Ferner ist an der Unterseite ein in Längsrichtung ausgerichteter erster Schraubkanal 23 sowie an der Oberseite ein weiterer länglicher Schraubkanal 24 gebildet. Der untere Schraubkanal 23 dient dabei zum Befestigen stirnseitiger Abschlussplatten 35 für das Leuchtengehäuse. Dies erfolgt mit zwei Schrauben 36, die jeweils in entsprechende Öffnungen der Stirnplatten 36 eingreifen und dann in den Schraubkanal 23 eingeschraubt werden. Der obere Schraubkanal 24 dient wiederum dazu, mit Hilfe entsprechender Schrauben 37 (siehe Fig. 9) einen Haltewinkel 30 anzuschrauben. Dieser dient einerseits der Halterung der Lampenfassung 31 sowie andererseits der Befestigung eines Aufhängeelements 40, an dem letztendlich das Kabel 41 zur Aufhängung der Leuchte 1 befestigt ist. In diesem Sinne können also sämtliche Komponenten der Leuchte 1 an den Profilteilen 20 befestigt werden.Furthermore, the holding elements 20 laterally projecting arms 22, which - as explained later - are used to hold the lateral profile elements. Further, a longitudinally oriented first screw 23 and at the top of a further elongated screw 24 is formed on the underside. The lower screw 23 serves to fasten end-side end plates 35 for the lamp housing. This is done with two screws 36, which engage respectively in corresponding openings of the end plates 36 and are then screwed into the screw 23. The upper screw channel 24 in turn serves to screw with the aid of appropriate screws 37 (see FIG. 9) a bracket 30. This serves on the one hand the holder of the lamp holder 31 and on the other hand, the attachment of a suspension element 40, to which ultimately the cable 41 is attached to suspend the lamp 1. In this sense, therefore, all components of the lamp 1 can be attached to the profile parts 20.
Die Seitenwände des Gehäuses der Leuchte 1 sind durch die Profilelemente 25 gebildet, welche einerseits einen an dem Proiϊlteil 20 anliegenden Arm 26 sowie eine obere Ausnehmung 27 aufweisen, deren Form mit dem vorstehenden Seitenarm 22 eines Profilteils 20 korrespondiert. Auch die Profilelemente können somit in einfacher Weise auf die als Halteelemente dienenden Profilteile 20 aufgeschoben werden. An der Unterseite des Profilelements 25 wiederum ist eine Ausnehmung 28 vorgesehen, in die die seitlichen Leisten 15 der Rasterelemente 10 eingreifen können. Wie insbesondere der Schnittdarstellung in Fig. 9 entnommen werden kann, wird dementsprechend ein kompaktes längliches Leuchtengehäuse gebildet, welches aufgrund der verschiedenen Steck- bzw. Rastverbindungen zwischen den einzelnen Komponenten äußerst stabil ist.The side walls of the housing of the lamp 1 are formed by the profile elements 25, which on the one hand have a voltage applied to the Proiϊlteil 20 arm 26 and an upper recess 27 whose shape corresponds to the protruding side arm 22 of a profile part 20. The profile elements can thus be pushed in a simple manner on serving as holding elements 20 profile parts. On the underside of the profile element 25, in turn, a recess 28 is provided, into which the lateral strips 15 of the grid elements 10 can engage. As can be seen in particular from the sectional view in Fig. 9, a compact elongated luminaire housing is accordingly formed, which is extremely stable due to the different plug-in or latching connections between the individual components.
Die Besonderheit der zuvor erläuterten Komponenten der erfindungsgemäßen Leuchte 1 besteht nunmehr ferner darin, dass diese Komponenten derart ausgestaltet sind, dass auch eine seitliche Lichtabgabe erfolgen kann. Dies wird insbesondere dadurch erreicht, dass die Rasterelemente 10 mit einer Beschichtung versehen sind, welche einerseits reflektierend wirkt, um die gerichtete Lichtabgabe über die Topfreflektoren 13 zu ermöglichen, andererseits allerdings auch zumindest zu einem gewissen Grad lichtdurchlässig ist. Insbesondere die Seitenwände der Topfreflektoren 13 sind dabei für einen gewissen Teil des von der Lichtquelle 3 abgegebenen Lichts durchlässig. Da ferner auch die seitlichen Profilelemente 25 aus einem transparenten Material, vorzugsweise aus einem transparenten Kunststoff bestehen, kann über die Seitenwände des Leuchtengehäuses Licht abgegeben werden. Die Menge des abgegebenen Lichts ist dabei von der Ausgestaltung der Beschichtung der Rasterelemente 10 abhängig. Da vermieden werden soll, dass durch das seitlich abgegebene Licht Blendeffekte auftreten, ist die Beschichtung vorzugsweise derart ausgebildet, dass eine Durchlässigkeit im Bereich von etwa 2 - 10%, vorzugsweise im Bereich zwischen 2 - 6 % vorliegt. D.h. die Menge des seitlich abgegebenen Lichts ist verhältnismäßig gering, so dass hier keine Blendung zu befürchten ist. Im Übrigen können auch die Stirnplatten 35 transparent ausgebildet sein.The peculiarity of the previously explained components of the luminaire 1 according to the invention now further consists in the fact that these components are designed such that a lateral light emission can also take place. This is achieved, in particular, by the fact that the raster elements 10 are provided with a coating which, on the one hand, has a reflective effect in order to allow the directed light output via the poppet reflectors 13, but, on the other hand, is also translucent, at least to a certain extent. In particular, the side walls of the pot reflectors 13 are here permeable to a certain part of the light emitted by the light source 3. Furthermore, since the lateral profile elements 25 are made of a transparent material, preferably of a transparent plastic, light can be emitted via the side walls of the lamp housing. The amount of light emitted depends on the design of the coating of the raster elements 10. Since it is to be avoided that glare effects occur due to the light emitted from the side, the coating is preferably formed such that a permeability in the range of about 2-10%, preferably in the range between 2-6% is present. That is, the amount of light emitted laterally is relatively low, so that there is no fear of glare. Incidentally, the end plates 35 may be formed transparent.
Die spezielle Ausgestaltung bzw. Lichtdurchlässigkeit der Rasterelemente 10 einerseits und der Profilelemente 25 andererseits hat ferner auch zur Folge, dass aufgrund der Aufhellung des umgrenzenden Leuchtengehäuses durch die seitlichen Profilelemente 25 hindurch die Konturen der im Leuchteninneren angeordneten Elemente erkennbar sind. Insbesondere bei aktivierter Lichtquelle sind dabei die Formen der einzelnen Topfreflektoren 13 erkennbar, was zu einem interessanten optischen Effekt führt. Die erfindungsgemäße Leuchte 1 weist dementsprechend nicht nur in lichttechnischer Sicht gesehen hervorragende Eigenschaften auf, sondern ist darüber hinaus auch hinsichtlich ihres Erscheinungsbilds äußerst ansprechend.The special design or transparency of the grid elements 10 on the one hand and the profile elements 25 on the other hand also has the consequence that due to the brightening of the surrounding lamp housing through the lateral profile elements 25 through the contours of the elements arranged inside the lights are recognizable. In particular, when activated light source while the shapes of the individual pot reflectors 13 can be seen, resulting in an interesting optical effect. The luminaire 1 according to the invention accordingly has excellent properties, not only in terms of lighting technology, but is also extremely appealing in terms of its appearance.
Die Form der seitlichen Profilelemente kann selbstverständlich in unterschiedlichster Weise ausgestaltet sein. Als Beispiel zeigen die Fig. 10a bis 10g denkbare Varianten für derartige Profilelemente 25. Die verschiedenen Formen haben dabei einen verhältnismäßig geringfügigen Einfiuss auf die Lichtabstrahlcharakteristik der Leuchte 1, gleichzeitig verleihen Sie allerdings der Leuchte 1 jeweils ein sehr individuelles Aussehen. Dementsprechend kann die Leuchte 1 in dieser Hinsicht unterschiedlichsten Bedürfnissen in einfacher Weise angepasst werden.The shape of the lateral profile elements can of course be configured in different ways. As an example, Figs. 10a to 10g conceivable variants for such profile elements 25. The various shapes have a relatively minor effect on the Lichtabstrahlcharakteristik the lamp 1, at the same time, however, give the lamp 1 each have a very individual appearance. Accordingly, the luminaire 1 can be easily adapted to a wide variety of needs in this regard.
Abschließend zeigt Fig. 11 eine weitere denkbare Variante einer erfindungsgemäßen Leuchte. Bei dieser Leuchte 1 , bei der vergleichbare Komponenten mit gleichen Bezugszeichen versehen sind, sind die Profilelemente 25 als vertikale Seitenwände ausgebildet, welche lediglich über entsprechende Ausnehmungen mit den hervorstehenden Seitenarmen 22 der Profilteile 20 verbunden sind. Die Seitenwände bzw. Profilelemente 25 sind in diesem Fall leicht beabstandet von den Rasterelementen 10 angeordnet, was dazu fuhrt, dass die Leuchte 1 insgesamt nicht mehr als kompakt abgeschlossenes Gehäuse erscheint. Hinsichtlich der lichttechnischen Eigenschaften ergeben sich allerdings keine gravierenden Änderungen. Nach wie vor erfolgt die Lichtabgabe hauptsächlich gerichtet über die Topfretlektoren 13, so dass die erfindungsgemäße Leuchte 1 in gewohnter Weise zuverlässig zur Ausleuchtung von Büroräumen bzw. Arbeitsplätzen eingesetzt werden kann. Das gesamte Erscheinungsbild der Leuchte sowie die Ausleuchtung des Raums wird allerdings im Vergleich zum Stand der Technik weiter optimiert, da nunmehr auch zur Oberseite hin sowie über die Seitenwände der Leuchte, also über den gesamten Umfang hinweg Licht abgegeben wird. Finally, FIG. 11 shows a further conceivable variant of a luminaire according to the invention. In this luminaire 1, in which comparable components are provided with the same reference numerals, the profile elements 25 are formed as vertical side walls, which are connected only via corresponding recesses with the protruding side arms 22 of the profile parts 20. The side walls or profile elements 25 are arranged in this case slightly spaced from the grid elements 10, which leads to the fact that the lamp 1 does not appear a total of compact housing more complete. With regard to the lighting properties, however, there are no serious changes. As before, the Light output mainly directed over the pot reflectors 13, so that the lamp 1 according to the invention can be used reliably in the usual way for the illumination of offices or workplaces. The overall appearance of the lamp and the illumination of the room is, however, further optimized in comparison to the prior art, since now also to the top and over the side walls of the lamp, so over the entire circumference light is emitted.
