Description

Die vorliegende Erfindung betrifft eine Leuchte mit einer rohrförmigen Gasentladungslampe sowie einem konkav gekrümmten Reflektor, vor dem zu beiden Seiten der Lampe Lichtbeeinflussungselemente angeordnet sind.The present invention relates to a luminaire with a tubular Gas discharge lamp and a concave curved reflector, in front of both Side of the lamp light influencing elements are arranged.

Eine gattungsgemäße Leuchte ist beispielsweise aus der DE 100 06 410 A1 der Anmelderin bekannt und soll nachfolgend anhand von Fig. 3 kurz erläutert werden. Die einzelnen Elemente der Leuchte 100 sind dabei innerhalb eines kastenförmigen Leuchtengehäuses 107 angeordnet, das bei der Montage der Leuchte in der Decke eines zu beleuchtenden Raumes versenkt wird. Als Lichtquelle dient eine stabförmige Gasentladungslampe 101, unter der bzw. - in Abstrahlrichtung gesehen - vor der ein aus Seitenreflektoren und Querlamellen bestehendes Raster 106 angeordnet ist. Der Großteil des von der Lampe 101 abgegebenen Lichts wird über dieses Raster 106 nach unten abgestrahlt.A generic lamp is known for example from DE 100 06 410 A1 of Applicant known and will be explained below with reference to FIG. 3 briefly. The individual elements of the lamp 100 are within a box-shaped Luminaire housing 107 arranged, which when mounting the lamp in the ceiling a room to be illuminated is sunk. The light source is a rod-shaped Gas discharge lamp 101, under or - seen in the direction of radiation - in front of the one consisting of side reflectors and cross blades existing grid 106 is arranged. Of the Most of the light emitted by the lamp 101 becomes light through this grid 106 emitted downwards.

Die Gasentladungslampe 101 wird ferner von einem konkav gekrümmten Reflektor 102 überspannt, dessen Seitenflügel im Wesentlichen neben der Lampe 101 angeordnet sind. Vor den Seitenflügeln des Reflektors 102 und damit ebenfalls zu beiden Seiten neben der Lampe 101 ist ein Diffusor 103 angeordnet, der gemeinsam mit dem Reflektor 102 zwei seitlich neben der Lampe 101 angeordnete sogenannte Lichtkammern 104 einschließt. Hierzu laufen der Diffusor 103 und der Reflektor 102 jeweils an ihren von der Lampe 101 entfernten Enden zusammen.The gas discharge lamp 101 is further characterized by a concave curved reflector 102 spans, the side wing substantially next to the lamp 101st are arranged. In front of the side wings of the reflector 102 and thus also too Both sides of the lamp 101, a diffuser 103 is arranged in common with the reflector 102 two laterally adjacent to the lamp 101 arranged so-called Light chambers 104 includes. For this purpose, the diffuser 103 and the reflector 102 run each at their ends remote from the lamp 101 together.

Ein Teil des von der Lampe 101 abgegebenen Lichts wird über die mit dem Bezugszeichen 105 versehenen sogenannten Lichteintrittsflächen in die beiden Lichtkammern 104 eingekoppelt, an dem Reflektor 102 reflektiert und über den Diffusor 103 nach unten abgestrahlt. Hierdurch wird der das Leuchtenraster 106 umgebende Bereich der Leuchte 100 ebenfalls leicht aufgehellt, wodurch ein optisch ansprechender Beleuchtungseffekt erzielt wird. Die besondere Ausgestaltung der Lichtkammern 104 hat dabei zur Folge, dass der angestrebte optische Effekt bereits bei einer sehr geringen Bauhöhe bzw. Tiefe des Leuchtengehäuses 107 erzielt wird. So liegt beispielsweise das Verhältnis der Breite a einer Lichtkammer 104 zur Höhe b der Lichteintrittsfläche 105 im Bereich von etwa 4:1.A portion of the light emitted by the lamp 101 is the light with the Reference numeral 105 provided so-called light entry surfaces in the two Light chambers 104 coupled, reflected on the reflector 102 and on the Diffuser 103 radiated down. As a result, the lighting grid 106 surrounding area of the luminaire 100 also slightly lightened, creating a visual attractive lighting effect is achieved. The special embodiment of Light chambers 104 has the consequence that the desired optical effect already is achieved at a very low height or depth of the lamp housing 107. For example, the ratio of the width a of a light chamber 104 to the height b of the light entrance surface 105 in the range of about 4: 1.

Obwohl diese bekannte Leuchte aufgrund der hervorragenden optischen Eigenschaften breite Akzeptanz gefunden und sich in verschiedensten Anwendungsgebieten bewährt hat, bestehen Bestrebungen, den Aufbau der Leuchte weiter zu vereinfachen. Wie in Figur 3 dargestellt ist, ist bei der bekannten Leuchte der Diffusor 103 einstückig ausgebildet und bildet ein selbstragendes Kunststoffteil. Das Kunststoffteil ist dabei in seinen beiden Seitenbereichen konkav gekrümmt und besitzt eine zentrale Ausknickung, welche die gekrümmten Seitenbereiche miteinander verbindet und die Lampe 101 in ihrem oberen Bereich umgibt. Die Seitenbereiche der Ausknickung bilden dabei die Lichteintrittsflächen 105 für die beiden Lichtkammern 104. Ein derartiges Kunststoffteil wird beispielsweise aus Polymethylmethacrylat (PMMA) im Spritzgießverfahren gefertigt.Although this famous luminaire due to the excellent optical Properties found wide acceptance and varied in different Applications proven, there are efforts to build the luminaire further simplify. As shown in Figure 3, is in the known lamp the diffuser 103 is integrally formed and forms a self-supporting plastic part. The plastic part is concavely curved in its two side areas and has a central kink which defines the curved side areas connects to each other and surrounds the lamp 101 in its upper area. The Side regions of the buckling thereby form the light entry surfaces 105 for the two light chambers 104. Such a plastic part is made for example Polymethyl methacrylate (PMMA) manufactured by injection molding.

Die einteilige Ausgestaltung des Diffusors wird insofern als nachteilig angesehen, als hierdurch die Möglichkeiten, die Abmessungen der Leuchte zu variieren, eingeschränkt werden. Der Grund hierfür ist, dass zur Herstellung des einstückigen Diffusors ein speziell vorgefertigtes Werkzeug erforderlich ist, welches ausschließlich zur Herstellung des Diffusors in diesen bestimmten Abmessungen geeignet ist. Soll nun eine Leuchte mit anderen Abmessungen erstellt werden, so müsste hierfür ein weiteres Werkzeug zur Erstellung eines entsprechenden Kunststoffteiles mit den neuen Abmessungen bereitgestellt werden, wodurch jedoch die Herstellungskosten für die Leuchte insgesamt beträchtlich erhöht würden.The one-piece design of the diffuser is considered to be disadvantageous, as thus the possibilities to vary the dimensions of the luminaire, be restricted. The reason for this is that for the production of the one-piece Diffusers a specially prefabricated tool is required, which exclusively for the manufacture of the diffuser in these specific dimensions suitable is. If you want to create a luminaire with different dimensions, then would have this another tool for creating a corresponding Plastic part can be provided with the new dimensions, which, however the manufacturing cost of the lamp would be considerably increased overall.

Ein weiterer Nachteil besteht darin, dass der einstückige Diffusor in der dargestellten speziellen Form lediglich aus PMMA hergestellt werden kann. Dieses Material erfüllt in einigen Ländern der Europäischen Union (z.B. Frankreich) jedoch nicht die einschlägigen Brandschutzanforderungen. Um diese einzuhalten, müsste der Diffusor aus dem etwas widerstandsfähigeren Material Polycarbonat (PC) bestehen. Zwar ist es möglich, auch PC-Kunststoffteile im Spritzgießverfahren herzustellen, allerdings müsste hierfür wiederum ein eigenes Werkzeug verwendet werden, da Polycarbonat ein anderes Schrumpfverhalten als PMMA aufweist und somit die Maße nach dem Abkühlen des Kunststoffteils nicht mehr der Norm entsprechen würden.Another disadvantage is that the one-piece diffuser in the illustrated special form can only be made of PMMA. This material However, in some countries of the European Union (eg France) it does not meet the relevant fire safety requirements. To comply with this, the diffuser would have to Made of the slightly more resistant material polycarbonate (PC). Although is It is also possible to produce PC plastic parts by injection molding, however would have to use this again its own tool, since polycarbonate has a different shrinkage behavior than PMMA and thus the dimensions after the Cooling of the plastic part would no longer meet the standard.

Ein weiteres Problem bei der einstückigen Ausgestaltung des Diffusors 103 besteht ferner darin, dass es zu einem Wärmestau in dem die Lampe 101 umgebenen Bereich kommen kann, der unter anderem zu einer Reduzierung der Leuchtenleistung führt.Another problem with the one-piece design of the diffuser 103 consists Further, it causes heat accumulation in the area surrounding the lamp 101 can lead, among other things, to a reduction in luminaire performance.

Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde; eine Leuchte der eingangs beschriebenen Art zu schaffen, mit der die gleichen lichttechnischen Effekte wie bei der bekannten Leuchte erzielt werden können, wobei jedoch die zuvor genannten Nachteile vermieden werden. Dabei soll nach wie vor eine einfache Montage der verschiedenen Bauteile innerhalb des Leuchtengehäuses ermöglicht werden.The present invention is therefore based on the object; a lamp of to create the type described above, with the same lighting effects as can be achieved in the known lamp, but the previously mentioned disadvantages are avoided. It should still be a simple Assembly of the various components within the lamp housing allows become.

Die Aufgabe wird durch eine Leuchte, welche die Merkmale des Anspruchs 1 aufweist, bzw. durch ein Montageelement gemäß Anspruch 19 gelöst.The object is achieved by a luminaire, which has the features of claim 1 has, or solved by a mounting member according to claim 19.

Die erfindungsgemäße Leuchte besitzt zunächst eine in einem Leuchtengehäuse angeordnete rohrförmige Gasentladungslampe, einen die Lampe übergreifenden und mit seinen Seitenbereichen - von dem zu beleuchtenden Bereich aus gesehen - zu beiden Seiten neben der Lampe angeordneten konkav gekrümmten Reflektor sowie ebenfalls zu beiden Seiten neben der Lampe aber vor dem Reflektor angeordnete Lichtbeeinflussungselemente. Erfindungsgemäß sind der Reflektor und die Lichtbeeinflussungselemente mit Hilfe mindestens eines Montageelements zu einer Einheit zusammengefügt, welche als Gesamtheit in dem Leuchtengehäuse montierbar bzw. demontierbar ist.The luminaire according to the invention initially has one in a luminaire housing arranged tubular gas discharge lamp, the lamp across and with its side areas - seen from the area to be illuminated - too both sides next to the lamp arranged concave curved reflector as well also arranged on both sides next to the lamp but in front of the reflector Light influencing elements. According to the reflector and the Light influencing elements by means of at least one mounting element to a Assembly unit, which can be mounted as a whole in the luminaire housing or is removable.

Gemäß der vorliegenden Erfindung wird somit durch die Verwendung des neuartigen Montageelements eine Baueinheit geschaffen, deren zentrale Elemente der Reflektor sowie die beiden seitlichen Lichtbeeinflussungselemente - bei denen es sich insbesondere um Diffusoren handeln kann - sind und die im Ganzen aus dem Leuchtengehäuse entfernt bzw. in dieses eingesetzt werden kann. Die Montage der Leuchte insgesamt ist somit sehr einfach.According to the present invention is thus by the use of the novel Mounting element created a unit whose central elements of the reflector as well as the two lateral light influencing elements - which are themselves in particular can act around diffusers - are and in the whole from the Luminaire housing removed or can be used in this. The assembly of Light overall is thus very simple.

Die Verwendung des erfindungsgemäßen Montageelements gestattet es dabei, den Diffusor - im Gegensatz zu der bekannten Leuchte - aus zwei getrennten Bauelementen zu bilden. Es ist also nicht mehr erforderlich, ein einstückiges, komplexes Kunststoffteil zu verwenden, weshalb der Aufwand zur Herstellung der Leuchte extrem reduziert wird. Insbesondere besteht die Möglichkeit, den zu beiden Seiten neben der Lampe angeordneten Diffusor aus ebenen Platten zu bilden. Die neuartige Ausgestaltung der Leuchte ermöglichst es nunmehr allerdings auch, anstelle von Diffusorscheiben andere Lichtbeeinflussungsmittel - beispielsweise Lochbleche oder Prismenscheiben - als Abstrahlelemente für die beiden Lichtkammern zu verwenden. Es bestehen damit zusätzliche Möglichkeiten zur Ausgestaltung der Leuchte, wodurch weitere Anwendungsgebiete erschlossen werden.The use of the mounting element according to the invention makes it possible to the Diffuser - in contrast to the known luminaire - made of two separate To form components. So it is no longer necessary to have a one-piece, complex plastic part to use, which is why the effort to produce the Lamp is extremely reduced. In particular, there is the possibility that to both To form sides next to the lamp arranged diffuser of flat plates. The However, a novel design of the luminaire makes it possible, instead of diffuser discs other light influencing means - for example Perforated sheets or prismatic disks - as radiating elements for the two To use light chambers. There are thus additional possibilities for Design of the luminaire, thereby opening up further areas of application become.

Ein sich aus der erfindungsgemäßen Ausgestaltung ergebener weiterer Vorteil besteht darin, dass die in Figur 3 mit den Bezugszeichen 105 versehenen Lichteintrittsflächen nicht mehr abgedeckt sind, d.h. die neben der Lampe angeordneten Lichtkammern sind zu der rohrförmigen Gasentladungslampe hin offen. Zum Einen wird hierdurch der Anteil an Licht, der in die Lichtkammern eingekoppelt wird, erhöht, zum Anderen kann ein Wärmestau im Bereich der Lampe und damit ein Wirkungsverlust und eine geringere Lichtausbeute vermieden werden.There is a further advantage resulting from the embodiment according to the invention in that those provided with the reference numeral 105 in FIG Light entry surfaces are no longer covered, i. the next to the lamp arranged light chambers are to the tubular gas discharge lamp open. On the one hand, this causes the proportion of light that enters the light chambers coupled, increased, on the other hand, a heat accumulation in the area of the lamp and thus a loss of efficiency and a lower light output can be avoided.

Das erfindungsgemäße Montageelement, von dem vorzugsweise zwei zur Bildung der Baueinheit verwendet werden, ist vorzugsweise bügelartig ausgestaltet und besteht aus zwei seitlich abstehenden Seitenarmen zum Halten des Reflektors sowie aus einem die Seitenarme miteinander verbindenden Mittelbereich. Die Seitenarme können dabei jeweils konkav gekrümmt sein und den Reflektor in der gewünschten Form halten bzw. die Krümmung des Reflektors bestimmen. Der Mittelbereich kann zwei senkrecht zur Erstreckungsrichtung der Seitenarme angeordnete Füße aufweisen, welche im montierten Zustand zu beiden Seiten neben der Gasentladungslampe angeordnet sind und Haltemittel zur Halterung weiterer Lichtbeeinflussungselemente aufweisen. Diese Haltemittel können in Form von Schlitzen realisiert werden, in welche die weiteren Lichtbeeinflussungselemente eingeschoben werden können. Beispielsweise besteht hierdurch die Möglichkeit, in den beiden Übergangsbereichen zu den Lichtkammern Farbfilter anzuordnen und hiermit dem über die Lichtkammern abgestrahlten Licht einen anderen Farbton zu verleihen.The mounting element according to the invention, of which preferably two for formation the unit can be used, preferably designed like a bow and consists of two laterally projecting side arms for holding the reflector as well from a middle region connecting the side arms. The side arms can each be concavely curved and the reflector in the desired Hold the shape or determine the curvature of the reflector. The middle area can two perpendicular to the extension direction of the side arms arranged feet which in the mounted state on both sides next to the Gas discharge lamp are arranged and holding means for holding another Have light influencing elements. These holding means can be in the form of Slots are realized, in which the other light influencing elements can be inserted. For example, there is the possibility in to arrange the two transition areas to the light chambers color filter and hereby assign a different hue to the light emitted via the light chambers to lend.

Die Füße des bügelartigen Montageelements weisen ferner vorzugsweise Vorsprünge auf, in welche die neben der Lampe angeordneten Lichtbeeinflussungselemente eingehängt werden können. In ihren der Lampe abgewandten Endbereichen sind die Lichtbeeinflussungselemente dann vorzugsweise mit dem Reflektor verklemmt, so dass die angestrebte Baueinheit aus Reflektor, Diffusoren und Montageelementen erzielt wird.The feet of the bow-shaped mounting member further preferably have projections on, in which the arranged next to the lamp light influencing elements can be hung. In their end portions facing away from the lamp are the Light influencing elements then preferably clamped to the reflector, so that the desired assembly of reflector, diffusers and mounting elements is achieved.

Vor der Lampe kann ferner ein weiteres Lichtbeeinflussungselement angeordnet werden, bei dem es sich insbesondere um ein Leuchtenraster oder um ein Lochblech handeln kann. Auch dieses Element wird vorzugsweise an die Unterseite des Montageelements angeklippst, so dass keine weiteren Befestigungsmittel erforderlich sind.In front of the lamp, a further light-influencing element can furthermore be arranged which is in particular a luminaire grid or a perforated plate can act. Also, this element is preferably attached to the underside of Anklappst mounting element, so that no further fastening means required are.

Insgesamt gesehen wird somit eine Leuchte geschaffen, welche hinsichtlich ihrer lichttechnischen Eigenschaften zumindest die gleichen Möglichkeiten wie die in Figur 3 dargestellte bekannte Leuchte eröffnet, wobei jedoch die vorliegende Leuchte einfacher und kostengünstiger hergestellt werden kann. Gleichzeitig wird eine Möglichkeit geschaffen, die wesentlichen Bestandteile der Leuchte auf einfache Weise in einem Gehäuse zu montieren.Overall, therefore, a lamp is created, which in terms of their Photometric properties at least the same possibilities as those in Figure 3 illustrated known lamp opens, but the present Lamp can be made easier and cheaper. At the same time created a way to simplify the essential components of the luminaire Way to mount in a housing.

a known from the prior art lamp.

Bevor die erfindungsgemäße Leuchte in ihrer Gesamtheit besprochen wird, soll zunächst anhand von Figur 1 das zentrale Element der vorliegenden Erfindung, nämlich das für die Bildung der Baueinheit verantwortliche Montageelement erläutert werden.Before the luminaire according to the invention is discussed in its entirety, should first with reference to Figure 1, the central element of the present invention, namely explained the responsible for the formation of the assembly unit assembly become.

Das in Figur 1 dargestellte bügelartige und vorzugsweise aus Metall bestehende Montageelement 10 besteht aus einem Mittelbereich 11, von dem sich zwei Seitenarme 12 seitlich erstrecken. Die Seitenarme 12 sind leicht konkav gekrümmt und weisen an ihren Enden jeweils verdrehbare Rastflügel 13 auf, die zur Verrastung mit dem Reflektor vorgesehen sind.The bow-shaped and preferably made of metal shown in Figure 1 Mounting element 10 consists of a central region 11, of which two Side arms 12 extend laterally. The side arms 12 are slightly concave curved and have at their ends in each case rotatable latching wings 13 which are for latching are provided with the reflector.

Der Mittelbereich 11 besteht aus zwei senkrecht zur Erstreckungsrichtung der Seitenarme 12 angeordneten Füße 14, die an ihren unteren Endbereichen Rasthaken oder Vorsprünge 16 zur Halterung der die Lichtkammern abschließenden Lichtbeeinflussungselemente aufweisen. Die Füße 14 sind im montierten Zustand der Baueinheit zu beiden Seiten neben der Lampe bzw. den Lampen angeordnet und weisen ferner zwei sich in Längsrichtung der Füße erstreckende Schlitzte 15 auf, in welche zusätzliche Lichtbeeinflussungselemente eingeschoben werden können. Diese eingeschobenen Lichtbeeinflussungselemente befinden sich dann im montierten Zustand in dem Übergangsbereich von den Lichtquellen zu den Lichtkammern und beeinflussen somit das über die Lichtkammern abgegebene Licht. Vorzugsweise werden in die Schlitze 15 Farbfilter eingeschoben, wodurch die beiden Lichtkammern in einem im Vergleich zu dem direkt abgestrahlten Licht der Lampen veränderten Farbton erscheinen.The central region 11 consists of two perpendicular to the extension direction of the Side arms 12 arranged feet 14, the latching hooks at their lower end portions or projections 16 for holding the light chambers final Have light influencing elements. The feet 14 are in the assembled state of Assembly arranged on both sides next to the lamp or lamps and further comprise two in the longitudinal direction of the feet extending slit 15, in which additional light influencing elements can be inserted. These inserted light influencing elements are then in the mounted State in the transition region from the light sources to the light chambers and thus influence the light emitted via the light chambers. Preferably 15 color filters are inserted into the slots, whereby the two Light chambers in a compared to the directly emitted light of the lamps changed hue appear.

Im oberen Bereich des Mittelteils 11 ist ferner eine Befestigungslasche 17 vorgesehen, mit deren Hilfe das Montageelement 10 und damit die gesamte aus den Montageelementen, dem Reflektor und den Lichtbeeinflussungselementen bestehende Baueinheit in einem Leuchtengehäuse verankert werden kann.In the upper region of the middle part 11 is also a fastening tab 17th provided with the help of the mounting element 10 and thus the entire from the Mounting elements, the reflector and the light influencing elements existing Assembly can be anchored in a luminaire housing.

Die Funktionsweise des Montageelements 10 wird in Figur 2 deutlich, welche die erfindungsgemäße Leuchte 1 in ihrer Gesamtheit zeigt. Als Ausführungsbeispiel ist dabei eine Deckeneinbauleuchte dargestellt, deren Elemente in einem kastenförmigen Leuchtengehäuse 20 angeordnet sind, das mit Hilfe von - nicht dargestellten - Montagemitteln in der Decke eines zu beleuchtenden Raumes versenkt wird.The operation of the mounting member 10 is clear in Figure 2, which the Inventive lamp 1 in its entirety shows. As an embodiment is a recessed ceiling light is shown, whose elements are in a box-shaped Luminaire housing 20 are arranged, which by means of - not shown - Mounting means in the ceiling of a room to be illuminated is sunk.

Als Lichtquelle dient eine Gasentladungslampe 2, unter der ein aus Seitenreflektoren und Querlamellen bestehendes Leuchtenraster 6 angeordnet ist. Ebenso wie bei der in Figur 3 dargestellten bekannten Leuchte wird ein Großteil des von der Lampe 1 - bei der es sich vorzugsweise um eine Leuchtstofflampe handelt - abgegebenen Lichts über das Raster 6 nach unten abgestrahlt, wobei die Strukturen und Abmessungen der Reflektoren und Lamellen derart gewählt sind, dass dieses nach unten abgestrahlte Licht zu einem gewissem Grad querentblendet ist. Die erfindungsgemäße Leuchte ist damit insbesondere auch zur Beleuchtung von Räumen mit Bildschirmarbeitsplätzen geeignet, da Blendeffekte an Bildschirmoberflächen sowie für in dem Raum anwesende Personen weitestgehend vermieden werden.The light source is a gas discharge lamp 2, under the one from side reflectors and transverse blades existing light grid 6 is arranged. As with the in Figure 3 illustrated known lamp is a major part of the lamp of the first - Which is preferably a fluorescent lamp - delivered Light emitted down the grid 6 down, taking the structures and Dimensions of the reflectors and fins are chosen such that this after down radiated light to a certain degree is cross-faded. The Lamp according to the invention is thus in particular also for the illumination of rooms suitable with VDU workstations, as glare effects on screen surfaces and for persons present in the room as far as possible.

Anstelle des dargestellten Rasters 6 könnten auch ein Lochblech, welches beispielsweise mit Folien hinterlegt ist, oder andere optische Elemente verwendet werden, beispielsweise Diffusoren oder Prismenstrukturen. Ferner besteht selbstverständlich auch die Möglichkeit, die Leuchte 1 mit mehreren Gasentladungslampen auszustatten.Instead of the illustrated grid 6 could also be a perforated plate, which For example, with films deposited, or other optical elements used be, for example, diffusers or prismatic structures. It also exists Of course, the possibility of the lamp 1 with several Equip gas discharge lamps.

Zu beiden Seiten neben der Lampe 2 befinden sich zwei Lichtkammern 5, über die ein weiterer Teil des von der Lampe 2 abgegebenen Lichts abgestrahlt wird. Die Lichtkammern 5 werden zunächst von einem Reflektor 3 gebildet, der den mittleren Bereich der Leuchte 1 mit der Lampe 2 übergreift und mit seinen beiden Seitenbereichen - von dem zu beleuchtenden Bereich aus gesehen - neben der Lampe 1 angeordnet ist. Vor den Seitenbereichen des Reflektors 3 ist jeweils eine Diffusorplatte 4 angeordnet, wobei der Reflektor 3 und die beiden Diffusorplatten 4 an den von der Lampe 2 entfernten Enden jeweils zusammenlaufen und somit die Lichtkammern 5 einschließen. Die Lichteintrittsflächen für die beiden Lichtkammern 5 werden jeweils von den Oberkanten des Rasters 6 und dem Reflektor 3 begrenzt. Da sich die Diffusorplatten 4 jeweils bis zur Oberkante der entsprechenden Seitenwand des Rasters 6 hin erstrecken, wird vermieden, dass die oberhalb des Rasters angeordnete Lampe 2 von der Seite her gesehen direkt betrachtet werden kann und damit Blendeffekte entstehen.On both sides next to the lamp 2 there are two light chambers 5, over the a further part of the light emitted by the lamp 2 is emitted. The Light chambers 5 are first formed by a reflector 3, the middle Area of the lamp 1 with the lamp 2 overlaps and with his two Side areas - viewed from the area to be illuminated - next to the lamp 1 is arranged. In front of the side areas of the reflector 3 is one each Diffuser plate 4 is arranged, wherein the reflector 3 and the two diffuser plates 4th converge at the remote from the lamp 2 ends each and thus the Include light chambers 5. The light entry surfaces for the two light chambers 5 are each bounded by the upper edges of the grid 6 and the reflector 3. Since the diffuser plates 4 each up to the top of the corresponding Side wall of the grid 6 out, it is avoided that above the Grid arranged lamp 2 viewed directly from the side can and thus dazzle.

Die Anordnung und Halterung des Reflektors 3 und der Diffusoren 4 in der dargestellten Weise erfolgt in erster Linie durch zwei in Längsrichtung der Lampe 2 verteilt angeordnete Montageelemente 10. Die Montageelemente 10 durchgreifen dabei jeweils zwei in dem Reflektor 3 angeordnete Schlitze derart, dass sie mit ihren Seitenarmen 12 oberhalb des Reflektors 3 und mit ihren Füßen 14 unterhalb des Reflektors 3 angeordnet sind. Eine Befestigung des Reflektors 3 an den Montageelementen 10 erfolgt mit Hilfe der Rastflügel 13, die zusätzliche Rastschlitze in dem Reflektor 3 durchgreifen und nach dem Verdrehen derselben mit diesem verrasten.The arrangement and mounting of the reflector 3 and the diffusers 4 in the illustrated manner takes place primarily by two longitudinally of the lamp. 2 arranged distributed mounting elements 10. The mounting elements 10 pass through in each case two arranged in the reflector 3 slots such that they with their Side arms 12 above the reflector 3 and with their feet 14 below the Reflectors 3 are arranged. An attachment of the reflector 3 to the Mounting elements 10 takes place with the aid of the latching wings 13, the additional locking slots pass through in the reflector 3 and after twisting the same with this lock.

Ein wesentliches Merkmal dieser Anordnung besteht darin, dass die Seitenflügel 12 der Montageelemente 10 auf der Oberseite des Reflektors 3 aufliegen und die Krümmung des Reflektors aufrechterhalten bzw. bestimmen. Hierdurch wird der Reflektor 3 unter Vorspannung gekrümmt wodurch er gleichzeitig auch in die Lage versetzt wird, die Diffusorplatten 4 an ihren Außenbereichen zu halten. Hierfür weist der Reflektor 3 in seinen Endbereichen Umkröpfungen 3a auf, in welche die Endbereiche der Diffusorplatten 4 eingreifen können. An ihren der Lampe 2 zugewandten Enden hingegen greifen die Diffusorplatten 4 mit ihren Randbereichen 4a in die Rastvorsprünge 16 des Montageelements 10 ein. Insgesamt wird hierdurch eine aus den beiden Montageelementen 10, dem Reflektor 3 und den beiden Diffusorplatten 4 bestehende Baueinheit gebildet, die als Gesamtheit in das Gehäuse 20 der Lampe 1 eingesetzt und montiert bzw. wieder demontiert werden kann. Die Verankerung dieser Baueinheit in dem Gehäuse 20 erfolgt dabei zum Einen durch die Montageelementen 10 bzw. deren Befestigungslaschen 17 sowie zum Anderen durch die beiden Randbereiche 3a des Reflektors 3, die in entsprechende Rastausnehmungen 21 des Gehäuses 20 eingreifen.An essential feature of this arrangement is that the side wings 12th the mounting elements 10 rest on the top of the reflector 3 and the Maintain or determine the curvature of the reflector. This will be the Reflector 3 curved under bias whereby he also in the same position is added to keep the diffuser plates 4 at their outer areas. For this purpose points the reflector 3 in its end regions turnarounds 3 a, in which the End portions of the diffuser plates 4 can intervene. At her the lamp 2 facing ends, however, the diffuser plates 4 engage with their edge regions 4a in the locking projections 16 of the mounting member 10 a. Overall, this will one of the two mounting elements 10, the reflector 3 and the two Diffuser plates 4 existing assembly formed as a whole in the housing 20 of the lamp 1 can be used and mounted or disassembled. The Anchoring this unit in the housing 20 takes place on the one hand by the Mounting elements 10 and their attachment tabs 17 and the other by the two edge portions 3a of the reflector 3, which in corresponding Engaging recesses 21 of the housing 20 engage.

Durch die Bildung der Baueinheit wird somit eine sehr einfache Montage bzw. Demontage der Leuchte 1 ermöglicht. Nach Montage der Baueinheit in dem Leuchtengehäuse 20 werden die zu beiden Seiten neben der Lampe 2 angeordneten Lichtkammern 5 gebildet, über die ein Teil des von der Lampe 2 abgegebenen Lichts seitlich abgegeben wird. Der Übergang der Lichtstrahlen von dem Bereich mit der Lampe 2 in die seitlichen Lichtkammern 5 erfolgt dabei zunächst ungehindert, da - abgesehen von den Füßen 14 der Montageelemente 10 keine weiteren Elemente neben der Lampe 2 angeordnet sind. Allerdings besteht die Möglichkeit, in die Schlitze der Füße 14 der Montageelemente 10 längliche Farbfilter einzuschieben, so dass das in die Lichtkammern 5 übertretene Licht farblich verändert wird. Der das Leuchtenraster 6 umgebene Bereich erscheint damit in einem anderen Farbton, wodurch ansprechende Beleuchtungseffekte erzielt werden können. Selbst mit eingeschobenen Farbfiltern wird jedoch kein luftdichter Abschluss des die Lampe 2 umgebenen Bereichs erzielt, so dass nach wie vor im Vergleich zu der bekannten Leuchte in Figur 3 ein besserer Wärmeaustausch erzielt wird und somit Verluste in der Leuchtleistung reduziert werden.The formation of the unit is thus a very simple assembly or Disassembly of the lamp 1 allows. After mounting the unit in the Luminaire housing 20 are arranged on both sides of the lamp 2 Light chambers 5 formed over which a part of the light emitted from the lamp 2 is discharged laterally. The transition of the light rays from the area with the Lamp 2 in the lateral light chambers 5 is initially unhindered, there - apart from the feet 14 of the mounting elements 10 no further elements are arranged next to the lamp 2. However, there is a possibility in the Slots of the feet 14 of the mounting elements 10 to insert elongated color filter, so the light passing into the light chambers 5 is changed in color. The that Luminous grid 6 surrounded area thus appears in a different hue, whereby attractive lighting effects can be achieved. Even with However, inserted color filters is not airtight completion of the lamp. 2 achieved area, so that still compared to the known In Figure 3 a better heat exchange is achieved and thus losses in the luminous power can be reduced.

Ein Vorteil der erfindungsgemäßen Ausstattung besteht insbesondere darin, dass die beiden Diffusoren 4 aus Kunststoffplatten gebildet werden können, die nun nicht mehr im Spritzgießverfahren hergestellt werden müssen. Hierdurch können ohne zusätzlichen Kostenaufwand Leuchten in verschiedenen Abmessungen realisiert werden, da das Ausschneiden von Kunststoffplatten in den gewünschten Größen deutlich einfacher durchzuführen ist. Darüber hinaus können die Diffusorplatten nunmehr wahlweise aus PMMA oder PC hergestellt werden. Alternativ dazu besteht jedoch auch die Möglichkeit, anstelle von Diffusorscheiben andere Lichtbeeinflussungselemente, beispielsweise Prismenscheiben oder Lochbleche zu verwenden.An advantage of the inventive equipment is in particular that the Both diffusers 4 can be made of plastic plates that are not more must be produced by injection molding. This can be done without additional cost of lighting realized in different dimensions Be as cutting out of plastic sheets in the desired sizes is much easier to perform. In addition, the diffuser plates can now optionally made of PMMA or PC. Alternatively, it exists but also the possibility of replacing diffuser discs with others Light influencing elements, such as prismatic disks or perforated plates to use.

Insgesamt wird somit durch die vorliegende Erfindung eine Leuchte geschaffen, welche hinsichtlich ihrer lichttechnischen Eigenschaften vergleichbar mit der bisher bekannten Leuchte ist. Auch das Erscheinungsbild der vorliegenden Leuchte gleicht im Wesentlichen der bereits bekannten Leuchte, wobei jedoch durch die vorliegende Erfindung die Herstellung deutlich vereinfacht und kostengünstiger gestaltet wird. Darüber hinaus wird die Montage bzw. Demontage der Leuchte durch die erfindungsgemäße Baueinheit besonders einfach und elegant gestaltet.Overall, a luminaire is thus created by the present invention, which in terms of their lighting properties comparable to the previous known light is. The appearance of the present lamp is similar essentially the already known lamp, but by the present Invention, the production is significantly simplified and made cheaper. In addition, the assembly or disassembly of the lamp by the inventive unit designed particularly simple and elegant.
