Description

Die Erfindung betrifft eine Leuchte nach dem Oberbegriff des Anspruchs 1.The invention relates to a luminaire according to the preamble of claim 1.

Bei einer Leuchte dieser Art handelt es sich um eine übliche Konstruktion mit einer Gehäusewanne, einer in der Gehäusewanne befindlichen Lampenfassung, elektrischen Anschluss- und Betriebsmitteln für die Leuchte, eine Abdeckung für die Gehäusewanne aus lichtdurchlässigem Material und Verschlussmitteln zum lösbaren Befestigen der Abdeckung an der Gehäusewanne.In a lamp of this type is a common construction with a housing pan, a housing located in the lamp socket, electrical connection and equipment for the lamp, a cover for the housing tray of translucent material and closure means for releasably securing the cover to the housing tray ,

Eine Leuchte dieser Art weist Befestigungsmittel zum unmittelbaren oder mittelbaren Befestigen an einer Wand oder einer Decke auf. Im letzteren Fall kann die Leuchte direkt oder in einer mittels Bändern, Ketten oder Bändeln abgehängten Anordnung an der Decke befestigt sein.A luminaire of this type has fastening means for direct or indirect attachment to a wall or a ceiling. In the latter case, the lamp can be attached directly or in a suspended by means of ribbons, chains or cords arrangement on the ceiling.

Bei einer vorliegenden Leuchte bedarf es aus verschiedenen Gründen in bestimmten oder unbestimmten Zeitabständen eines Zugangs zum Innenraum der Gehäusewanne, um z.B. die Lichtquelle oder elektrische Betriebsmittel auszutauschen oder Wartungsarbeiten durchzuführen. Für einen Zugang müssen die Verschlussmittel und die Abdeckung geöffnet werden, und nach dem Zugang wieder geschlossen werden. Diese Maßnahmen erfordern bei bekannten Leuchten einen erheblichen Aufwand an Handhabung und Zeit, wodurch beträchtliche Betriebskosten für die Leuchte vorgegeben sind. Es besteht somit die Forderung nach einem einfachen und schnellen Zugang zum Gehäuseinnenraum.In a present luminaire, for various reasons, at certain or indefinite intervals, access to the interior of the casing tub is required, e.g. replace the light source or electrical equipment or perform maintenance. For access, the closure means and the cover must be opened and closed again after access. These measures require a considerable amount of handling and time in known lights, whereby considerable operating costs for the lamp are given. There is thus the demand for a simple and quick access to the housing interior.

Dabei ist auch zu berücksichtigen, dass für eine Leuchte eine möglichst ungehinderte Lichtabstrahlung erstrebenswert und außerdem die Abstrahlseite der Leuchte eine Sichtseite ist, die gestaltenden Einfluss auf den zu beleuchtenden Raum nimmt. Insbesondere für einen Wohn- oder Büroraum ist für die Leuchte deshalb eine Konstruktion gefordert, die ein gutes Erscheinungsbild hat.It should also be considered that desirable for a lamp as unobstructed light emission and also the emission side of the lamp is a visible side that takes formative influence on the room to be illuminated. Therefore, especially for a living or office space, a construction is required for the luminaire, which has a good appearance.

Bekannte Verschlussmittel zum lösbaren Befestigen der Abdeckung an der Gehäusewanne durchsetzen die Abdeckung in Durchführungslöchern. Hierdurch werden nicht nur das Erscheinungsbild der Leuchte und deren Eignung für Wohn oder Büroräume beeinträchtigt, sondern es können auch Verunreinigungen wie Staub, Feuchtigkeit, z. B. Wasser oder insbesondere Spritzwasser, in den Gehäuseinnenraum gelangen oder wenigstens an den Durchführungsfugen ansammeln, was unerwünscht ist.Known closure means for releasably securing the cover to the housing pan pass through the cover in feedthrough holes. hereby Not only are the appearance of the luminaire and its suitability for residential or office space affected, but it can also impurities such as dust, moisture, z. As water or spray in particular, get into the housing interior or at least accumulate at the feed-through joints, which is undesirable.

Andere beispielsweise in der US 3,355,583 , FR 1.171.096 , US 3,593,021 und der DE 101 41 196 A1 offenbarte Verschlussmittel weisen einen Magneten auf, der mit einem Gegenelement zur Verbindung von Gehäusewanne und Abdeckung kooperiert. Dabei ist eine zuverlässige Verbindung von Wanne bzw. Abdeckung mit dem Magneten bzw. dem Gegenelement jedoch besonderen Schwierigkeiten unterworfen, besonders wenn ein ansprechendes Erscheinungsbild der Leuchte erzielt werden soll,Others for example in the US 3,355,583 . FR 1,171,096 . US 3,593,021 and the DE 101 41 196 A1 disclosed closure means comprise a magnet which cooperates with a counter element for connecting the housing pan and cover. However, a reliable connection of the tub or cover with the magnet or the counter element is subject to particular difficulties, especially if an attractive appearance of the lamp should be achieved,

Der Erfindung liegt die Aufgabe zugrunde, eine Leuchte der eingangs angegebenen Art dahingehend zu verbessern, dass an der Außenseite der Scheibe keine Befestigungselemente vorhanden sind.The invention has for its object to improve a lamp of the type specified in that to the outside of the disc no fasteners are available.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen beschrieben.This object is solved by the features of claim 1. Advantageous developments of the invention are described in the subclaims.

Bei der erfindungsgemäßen Leuchte greifen die Verschlussmittel nur an der Innenseite der Abdeckung an dieser an oder sie sind nur an der Innenseite der Abdeckung mit dieser verbunden. Hierdurch ist der mit der Abdeckung in Kontakt stehende Funktionsbereich der Verschlussmittel auf die Innenseite der Abdeckung verlagert bzw. beschränkt, wobei die Verschlussmittel vollständig im Gehäuseinnenraum angeordnet werden. Deshalb sind auch die mit der Abdeckung in Verschlussfunktion befindlichen Teile der Verschlussmittel im Gehäuseinnenraum angeordnet und somit von außen verdeckt und dem Blick von außen entzogen. Deshalb wird auch das bei der Blickrichtung auf die Außenseite der Abdeckung sichtbare Erscheinungsbild der Leuchte verbessert.In the lamp according to the invention, the closure means engage only on the inside of the cover on this or they are connected only on the inside of the cover with this. As a result, the functional area of the closure means which is in contact with the cover is displaced or restricted to the inside of the cover, the closure means being arranged completely in the housing interior. Therefore, the parts of the closure means with the cover in the closure function are arranged in the housing interior and thus hidden from the outside and removed from view from the outside. Therefore, the visual appearance of the luminaire which is visible when looking at the outside of the cover is also improved.

Es eignen sich erfindungsgemäß solche Verschlussmittel, deren gehäusewannenseitige Verschlussmittelteile und abdeckungsseitige Verschlussmittelteile durch Magnetkraft zusammenwirken und aneinander halten. Solche Verschlussmittel können wenigstens eine magnetische Haltevorrichtung bilden. Erfindungsgemäß ist vorgesehen, dass die Verschlussmittel einen mit einer Gehäusewanne verbundenen Magneten aufweisen.According to the invention, such closure means are suitable whose housing side-side closure means and cover-side closure means interact by magnetic force and hold one another. Such closure means may form at least one magnetic holding device. According to the invention, it is provided that the closure means have a magnet connected to a housing pan.

Eine magnetische Haltekraft eignet sich deshalb besonders gut für die Verschlussmittel, weil diese durch Abziehen der Abdeckung voneinander lösbar sind, z. B. durch manuellen Angriff an der Abdeckung mittels eines Saugkopfes. D. h. besondere, von außen zugängliche Bauteile an der Abdeckung zum Lösen der Verschlussmittel sind nicht erforderlich.A magnetic holding force is therefore particularly suitable for the closure means, because they are detachable from each other by peeling off the cover, z. B. by manual attack on the cover by means of a suction head. Ie. special, externally accessible components on the cover for releasing the closure means are not required.

Eine magnetische Haltevorrichtung ist auch deshalb vorteilhaft, weil sie sich mit einer geringen Bauhöhe verwirklichen lässt, wodurch auch eine geringe Bauhöhe für die Leuchte erreichbar ist. Sowohl ein Magnet der Haltevorrichtung als auch ein Gegenelement aus ferrogmagnetischem Material können in flacher Bauweise ausgebildet sein.A magnetic holding device is also advantageous because it can be realized with a low overall height, whereby a low overall height for the Luminaire is accessible. Both a magnet of the holding device and a counter-element made of ferromagnetic material may be formed in a flat design.

Zu diesem Vorteil trägt auch eine Ausbildung der Abdeckung als Scheibe bei. Außerdem wird hierdurch eine gute Lichtabstrahlung erreicht.To this advantage also contributes to a training of the cover as a disc. In addition, this achieves a good light emission.

Die Befestigung der der Abdeckung bzw. der Scheibe zugehörigen Verschlussmittelteile erfolgt vorzugsweise durch Kleben. Hierzu ist erfindungsgemäß vorgesehen, feste Schicht, insbesondere eine Keramikschicht, auf die Abdeckung bzw. die Scheibe aufzutragen, wobei die feste Schicht vorzugsweise im Bereich der Klebestellen ringförmig umläuft und vorzugsweise bei der Herstellung der Scheibe vorgefertigt ist. Erfindungsgemäß ist die feste Schicht zwischen einem Gegenelement an der Innenseite der Abdeckung, welches mit dem mit der Gehäusewanne verbundenen Magneten zusammenwirkt, angeordnet. Hierdurch lässt sich eine stabile Klebebefestigung erreichen.The attachment of the cover or the disc associated closure means parts is preferably carried out by gluing. For this purpose, the invention provides, solid layer, in particular a ceramic layer, to be applied to the cover or the disc, wherein the solid layer preferably in the region of the splices rotates annularly and is preferably prefabricated in the manufacture of the disc. According to the invention, the fixed layer is arranged between a counter element on the inside of the cover, which cooperates with the magnet connected to the housing pan. As a result, a stable adhesive attachment can be achieved.

Wenigstens zwei einander gegenüberliegend angeordnete magnetische Haltevorrichtungen lassen sich vorzugsweise an zwei im Gehäuseinnenraum einander gegenüberliegend angeordneten Geräteträgern realisieren, die die Gehäusewanne stabilisieren.At least two oppositely arranged magnetic holding devices can be realized preferably at two in the housing interior opposite each other arranged device carriers that stabilize the housing pan.

Es ist aus Sicherheitsgründen vorteilhaft, zwischen der Gehäusewanne und der Abdeckung bzw. Scheibe eine Abhängsicherung vorzusehen, die verhindert, dass die Abdeckung, z. B. nach ihrem Lösen, herunterfallen könnte. Eine solche Abhängsicherung lässt sich in einfacher und sicherer Weise als Seilzugsicherung ausbilden.It is advantageous for safety reasons, to provide a suspension between the housing and the cover or disc, which prevents the cover, z. B. after its release, could fall down. Such a suspension can be trained in a simple and safe way as Seilzugsicherung.

Es ist im weiteren vorteilhaft, zwischen der Gehäusewanne und der Abdeckung eine Zentriervorrichtung vorzusehen, die z. B. durch eine Steckausnehmung an dem einen Teil und einen Steckzapfen an dem anderen Teil, insbesondere an der Innenseite der Abdeckung, gebildet sein kann und eine genaue Positionierung der Abdeckung bezüglich der Gehäusewanne ermöglicht.It is further advantageous to provide a centering device between the housing pan and the cover, the z. Example, by a plug-in recess on one part and a plug-in pin on the other part, in particular on the inside of the cover, may be formed and allows accurate positioning of the cover with respect to the housing pan.

Gemäß einer Weiterbildung der Erfindung ist zwischen der Gehäusewanne und der Abdeckung bzw. Scheibe eine ringförmige Dichtung angeordnet, die vorzugsweise durch einen Dichtstrang aus elastisch verformbarem Material gebildet ist. Der Dichtstrang kann an der Abdeckung oder an der Gehäusewanne unlösbar befestigt sein, z. B. durch Kleben oder Anschäumen. Die erfindungsgemäße Ausgestaltung eignet sich deshalb sehr vorteilhaft für eine Reinraumleuchte, bei der der Gehäuseinnenraum dicht verschlossen sein soll, um ihn vor Verschmutzungen zu schützen und eine einfache und problemlose Reinigung der Leuchte zu gewährleisten.According to one embodiment of the invention, an annular seal is disposed between the housing pan and the cover or disc, which is preferably formed by a sealing strand of elastically deformable material. The sealing strip may be permanently attached to the cover or on the housing pan, z. B. by gluing or foaming. The embodiment of the invention is therefore very advantageous for a clean room lamp in which the interior of the housing should be sealed to protect it from contamination and to ensure easy and easy cleaning of the lamp.

Die Ringdichtung ist vorzugsweise am Umfangsrand der Gehäusewanne und der Abdeckung angeordnet, wobei sie die Verschlussmittel und auch die vorzugsweise vorhandene Zentriervorrichtung umringt und somit abdichtet und vor Verunreinigungen schützt. Die Ringdichtung ermöglicht auch eine - von innen gesehen - staub- und spritzwasserdichte Ausbildung der Leuchte. Eine Leuchte mit dieser Weiterbildung eignet sich deshalb auch für Räume von medizinischen Bereichen, insbesondere Untersuchungs- und Operationssälen, in denen zwecks Reinigung oder Desinfektion ein Bespritzen der Leuchte mit Desinfektionsmitteln stattfindet.The ring seal is preferably arranged on the peripheral edge of the housing pan and the cover, wherein the closure means and also preferably existing centering surrounds and thus seals and protects against contamination. The ring seal also allows - seen from the inside - dust and splash water proof design of the lamp. A luminaire with this development is therefore also suitable for rooms of medical areas, in particular examination and operating rooms, in which for the purpose of cleaning or disinfecting a splashing of the lamp takes place with disinfectants.

Weitere Weiterbildungsmerkmale der Erfindung ermöglichen eine einfache, kostengünstig herstellbare und einfache und schnell montierbare bzw. demontierbare Bauweise der Leuchte.Further development features of the invention allow a simple, inexpensive to produce and simple and easy to install or dismantle construction of the lamp.

Nachfolgend werden vorteilhafte Ausgestaltungen der Erfindung anhand von Ausführungsbeispielen und Zeichnungen näher erläutert. Es zeigt:

Die Hauptteile der in Fig. 1 in ihrer Gesamtheit mit 1 bezeichneten Leuchte sind eine Gehäusewanne 2, mindestens eine im Gehäuseinnenraum 3 angeordnete Fassung 4 für eine Lichtquelle 5, eine Abdeckung 6 zum Abdecken der Wannenöffnung 7, und Verschlussmittel 8 zum lösbaren Befestigen der Abdeckung 6 auf der Gehäusewanne 2.The main parts of in Fig. 1 1 in its entirety are a housing pan 2, at least one housing interior 3 arranged in the socket 4 for a light source 5, a cover 6 for covering the trough opening 7, and closure means 8 for releasably securing the cover 6 on the housing trough second

Beim vorliegenden Ausführungsbeispiel weist die Gehäusewanne 2 die Form eines vorzugsweise quaderförmigen Kastens auf mit einer Bodenwand 2a und vier von deren Rändern abstehenden Seitenwänden 2b, 2c, 2d, 2e, wobei bei einer vorzugsweise länglichen Form der Leuchte 1 zwei breitseitige Seitenwände 2b, 2c und zwei schmalseitige Seitenwände 2d, 2e, die einander gegenüberliegen und eine hier viereckige Umfangswand 2f bilden. Vom freien Rand 2g der Umfangswand 2f erstreckt sich ein Randstreifen 2h nach innen. Die sich parallel zur Bodenwand 2a erstreckende Breite des Randstreifens ist mit b bezeichnet. Der Randstreifen 2h ist vorzugsweise vom freien Rand 2g ausgehend um das Maß a vertieft geformt mit einem schrägen oder gerundeten Randstreifenabschnitt, der sich z. B. vom freien Rand 2g erstrecken kann. Der z. B. an allen Seiten z. B. mit einer gleichen Breite b ausgebildete Randstreifen 2h begrenzt mit seinem Innenrand die Wannenöffnung 7, die von der Abdeckung 6 abgedeckt ist und sich vorzugsweise bis zum freien Rand 2g erstreckt und somit der horizontalen Form und Größe der Gehäusewanne 2 entspricht.In the present embodiment, the housing pan 2 has the shape of a preferably cuboid box with a bottom wall 2a and four projecting from the edges side walls 2b, 2c, 2d, 2e, wherein in a preferably elongated shape of the lamp 1, two broad side walls 2b, 2c and two narrow side walls 2d, 2e, which are opposite to each other and form a quadrangular peripheral wall 2f here. From the free edge 2g of the peripheral wall 2f an edge strip 2h extends inwards. The width of the edge strip extending parallel to the bottom wall 2a is designated by b. The edge strip 2h is preferably formed from the free edge 2g recessed by the dimension a with an oblique or rounded edge strip portion, the z. B. can extend from the free edge 2g. The z. B. on all sides z. B. formed with a same width b edge strip 2h limited with its inner edge, the trough opening 7, which is covered by the cover 6 and preferably extends to the free edge 2g and thus corresponds to the horizontal shape and size of the housing trough 2.

Es sind ein oder mehrere Verschlussmittel 8 vorhanden, die einander gegenüberliegend im Randbereich des Gehäuseinnenraums 3 wirksam bzw. angeordnet sind und jeweils ein der Gehäusewanne 2 zugehöriges Verschlussteil 8a und ein der Abdeckung 6 zugehöriges Verschlussteil 8b aufweisen. Bei einer Leuchte 1 mit etwa gleich großen Längen- und Breitenabmessungen können zwei Verschlussmittel 8 einander gegenüberliegend angeordnet sein. Bei einer vorliegenden länglichen Leuchte 1, die insbesondere für eine längliche Lichtquelle ausgebildet ist, z. B. für eine Leuchtstoffröhre, ist es aus Gründen eines Gewichtsausgleichs vorteilhaft, mehrere Verschlussmittel 8 im Randbereich an den Breitseiten der Leuchte 1 anzuordnen, z. B. auf jeder Breitseite zwei Verschlussmittel 8 in den Endbereichen oder auch zusätzlich ein weiteres Verschlussmittel 8 im mittleren Bereich der jeweiligen Breitseite.One or more closure means 8 are present, which are effective or arranged opposite one another in the edge region of the housing interior 3 and each have a closure part 8a associated with the housing trough 2 and a closure part 8b associated with the cover 6. In a lamp 1 with approximately equal length and width dimensions, two closure means 8 can be arranged opposite one another. In a present elongated light 1, which is designed in particular for an elongated light source, for. As for a fluorescent tube, it is advantageous for reasons of weight balance to arrange a plurality of closure means 8 in the edge region on the broad sides of the lamp 1, z. B. on each broadside two closure means 8 in the end regions or in addition a further closure means 8 in the central region of the respective broadside.

Beim Ausführungsbeispiel sind die Verschlussmittel 8 jeweils durch eine Haltevorrichtung gebildet mit einem Permanent-Magnet 8d und einem Gegenelement 8c aus ferromagnetischem Material, wobei erfindungsgemäß das Gegenelement an der Abdeckung 6 und der Magnet 8d der Gehäusewanne 2 zugeordnet ist.In the exemplary embodiment, the closure means 8 are each formed by a holding device with a permanent magnet 8d and a counter element 8c of ferromagnetic material, wherein according to the invention the counter element is assigned to the cover 6 and the magnet 8d of the housing pan 2.

Eine magnetische Haltevorrichtung hat mehrere Vorteile. Zum einen bedarf sie keiner direkten manuellen Zugänglichkeit. Die Verschlusskraft der vorhandenen Haltevorrichtungen ist so groß, dass die Abdeckung 6 bei ihrer Anlage an der Gehäusewanne 2 sicher gehalten wird, jedoch auch so groß ist, dass durch eine manuell aufbringbare Zugkraft, z. B. durch einen Saugkopf an die Abdeckung und manuelles Ziehen der Magnetverschluss lösbar ist, wobei die Haltevorrichtungsteile voneinander gelöst werden. Dabei bedarf es keines direkten manuellen Angriffs an den Verschlussteilen 8a, 8b, sondern die Bedienungsperson kann manuell an der Abdeckung 6 angreifen, um die Magnetverschlüsse zu lösen. Die Magnetverschlüsse können somit unsichtbar im Gehäuseinnenraum 3 angeordnet werden, so dass sie an der dem zu beleuchtenden Raum zugewandten Sichtseite der Leuchte 1 nicht sichtbar sind. Es ist auch nicht erforderlich, dass das der Abdeckung 6 zugehörige Verschlussteil bzw. Magnetteil die Abdeckung 6 an ihrem Rand übergreift, wie es beim Stand der Technik notwendig ist.A magnetic holder has several advantages. First, it does not require direct manual accessibility. The closing force of the existing holding devices is so great that the cover 6 is held securely when it rests on the housing pan 2, but is also so large that by a manually applied tensile force, for. B. by a suction head to the cover and manual pulling the magnetic closure is releasable, wherein the holding device parts are detached from each other. It does not require a direct manual attack on the closure parts 8a, 8b, but the operator can manually attack the cover 6 to release the magnetic locks. The magnetic fasteners can thus be arranged invisibly in the housing interior 3 so that they are not visible on the visible side of the luminaire 1 facing the room to be illuminated are. It is also not necessary that the cover 6 associated closure part or magnetic part, the cover 6 overlaps at its edge, as is necessary in the prior art.

In Fig. 2 rechts ist der Magnet 8d nicht dargestellt.In Fig. 2 on the right, the magnet 8d is not shown.

Ein weiterer Vorteil eines Magnetverschlusses ist darin zu sehen, dass er mit niedriger Konstruktionshöhe ausgebildet werden kann und er deshalb nur verhältnismäßig wenig in den Gehäuseinnenraum 3 hineinragt und die Leuchte 1 mit verhältnismäßig geringer Konstruktionshöhe ausgebildet werden kann.Another advantage of a magnetic closure is the fact that it can be designed with low construction height and therefore it protrudes relatively little into the housing interior 3 and the lamp 1 can be formed with relatively low construction height.

Das der Abdeckung 6 zugehörige Gegenelement 8c kann flach ausgebildet sein und z. B. durch eine dünne Scheibe oder eine Folie aus ferromagnetischem Material gebildet sein, die auf der Innenseite 6b der Abdeckung 6 festgeklebt ist, hier auf der Innenseite 6b einer die Abdeckung bildenden Scheibe 6a aus durchsichtigem oder durchscheinenden Material, insbesondere Glas oder Kunststoff. Das der Gehäusewanne 2 zugehörige Verschlußteil 8a weist eine ebene der Abdeckung 6 zugewandte Wirkfläche auf. Um in der Verschlussstellung eine flächige Anlage der Magnetteile aneinander zu gewährleisten, ist das der Gehäusewanne 2 zugehörige Verschlußteil 8a vorzugsweise allseitig pendelbar gehalten.The cover 6 associated counter-element 8c may be formed flat and z. Example, be formed by a thin disc or a film of ferromagnetic material, which is glued to the inside 6b of the cover 6, here on the inside 6b of the cover forming a disc 6a of transparent or translucent material, in particular glass or plastic. The housing shell 2 associated closure part 8a has a flat of the cover 6 facing effective surface. In order to ensure a flat contact of the magnetic parts to one another in the closed position, the closure part 8a associated with the housing pan 2 is preferably held on all sides in a pendulum manner.

Beim Ausführungsbeispiel ist das der Gehäusewanne 3 zugehörige Magnetteil 8a durch einen Ring- oder Topfmagnet gebildet, in dessen Boden eine Kopfschraube 11 eingeschraubt ist, deren Kopf eine Tragvorrichtung 12 in einem Loch von oben durchfasst und darin mit seitlichem und vertikalen Bewegungsspiel gehalten ist.In the exemplary embodiment, the housing part 3 associated magnetic part 8a is formed by a ring or pot magnet, in the bottom of a cap screw 11 is screwed, the head of a support device 12 in a hole from above durchfasst and is held therein with lateral and vertical movement play.

Das der Gehäusewanne 2 zugehörige Verschlußteil 8a befindet sich innenseitig vom Randstreifen 2h in einer Höhe, in der es in Verbindung mit dem der Abdeckung 6 zugehörigen Verschlußteil 8b die Scheibe 6a in der Verschlussstellung in einer Position hält, in der ihre Innenseite 6b einen vorzugsweise kleinen Abstand c (Fig. 3) von der Gehäusewanne 2 hat.The housing part 2 associated closure part 8a is located inside the edge strip 2h at a height in which it holds in connection with the cover 6 associated closure member 8b the disc 6a in the closed position in which its inner side 6b is preferably a small distance c ( Fig. 3 ) of the housing tray 2 has.

Die Tragvorrichtung 12 weist eine das zugehörige Verschlußteil 8a tragende Tragschiene 13 und einen Geräteträger 14 auf, der an der zugehörigen Seitenwand 2b, 2c angeordnet und gehalten ist sowie sich über ein Großteil der Länge der Seitenwand 2b, 2c erstreckt. Auf der gegenüberliegenden Seite der Leuchte 1 ist die dort angeordnete Tragvorrichtung 12 bezüglich der Läugsmittelebene 15 der Leuchte spiegelsymmetrisch angeordnet und ausgebildet. Es wird deshalb die Tragvorrichtung 12 nur an der linken Seite beschrieben.The support device 12 has a corresponding closure member 8a supporting support rail 13 and a device carrier 14 which is arranged and held on the associated side wall 2b, 2c and extends over a large part of the length of the side wall 2b, 2c. On the opposite side of the lamp 1, the supporting device 12 arranged there is arranged with respect to the Läugsmittelebene 15 of the lamp mirror symmetry and formed. It is therefore described the support device 12 only on the left side.

Der Geräteträger 14 ist im Querschnitt vorzugsweise winkelförmig ausgebildet mit einem sich parallel zur zugehörigen Seitenwand 2b, 2c erstreckenden unteren und bis zum inneren Rand 2g erstreckenden Tragschenkel 14a und einem sich parallel zur Bodenwand 2a erstreckenden oberen Tragschenkel 14b, der an der Bodenwand 2a befestigt ist, z. B. durch nicht dargestellte Schrauben. Der obere Tragschenkel 14b kann an seinem inneren Rand einen sich nach oben bis zur Bodenwand 2a erstreckenden Schenkel 14c aufweisen, so daß sich ein zwischen letzterem und dem unteren Tragschenkel 14a erstreckender Schenkelabschnitt 14d sich in einem Abstand von der Bodenwand 2a befindet. An dem Tragschenkelabschnitt 14d kann ein elektrisches Vorschaltgerät 16 befestigt sein, das zu einer elektrischen Anschlußvorrichtung 17 gehört.The device carrier 14 is preferably angularly formed in cross section with a parallel to the associated side wall 2b, 2c extending lower and extending to the inner edge 2g support leg 14a and parallel to the bottom wall 2a extending upper support leg 14b, which is attached to the bottom wall 2a, z. B. by screws, not shown. The upper support leg 14b may have at its inner edge a leg 14c extending up to the bottom wall 2a, so that a leg portion 14d extending between the latter and the lower support leg 14a is at a distance from the bottom wall 2a. An electric ballast 16, which belongs to an electrical connection device 17, may be fastened to the support leg section 14d.

Die Tragschiene 13 ist vorzugsweise eine Profilschiene, z. B. eine U-Profilschiene, die in entsprechenden Schlitzen 18 von Tragstegen 19 horizontal eingeschoben sind, die vom unteren Tragschenkel 14a abstehen und vorzugsweise damit einteilig verbunden sind. Die Tragstege 19 können durch einen winkelförmigen Einschnitt 20 im Tragschenkel 14a freigeschnitten und nach innen um eine zugehörige vertikale Biegekante umgebogen sein.The support rail 13 is preferably a rail, z. As a U-profile rail, which are inserted horizontally in corresponding slots 18 of support webs 19, which protrude from the lower support legs 14a and are preferably integrally connected thereto. The support webs 19 may be cut free by an angular cut 20 in the support leg 14a and bent inwardly about an associated vertical bending edge.

Die Abdeckung 6 ist bezüglich der Gehäusewanne 2 abgedichtet. Beim Ausführungsbeispiel ist zwischen dem Randstreifen 2h und der Innenseite 6b ein ringförmiges Dichtelement 21 angeordnet, das vorzugsweise am Randstreifen 2h befestigt ist, z. B. angeklebt ist. Beim Ausführungsbeispiel ist das Dichtelement 21 ein z. B. im Querschnitt halbrundförmiger Dichtstrang aus elastisch komprimierbarem Material, der aufgeschäumt sein kann und eine glatte Oberfläche aufweist. In der Verschlußstellung der Abdeckung 6 ist das Dichtelement 21 elastisch zusammengedrückt.The cover 6 is sealed with respect to the housing trough 2. In the embodiment, an annular sealing element 21 is disposed between the edge strip 2h and the inner side 6b, which is preferably attached to the edge strip 2h, z. B. is glued. In the embodiment, the sealing element 21 is a z. B. in cross-section of a semicircular sealing strip made of elastically compressible material which may be foamed and has a smooth surface. In the closed position of the cover 6, the sealing element 21 is elastically compressed.

Das Gegenelement 8c ist z. B. durch Halteplatte 23 aus Stahl gebildet, die an die Innenseite 6b der Abdeckung 6 angeklebt ist. Beim Ausführungsbeispiel ist die Platte 23 durch einen Winkel mit einem aufrechten innenseitigen Schenkel 23a gebildet, der eine noch zu beschreibende Positionierfunktion erfüllt.The counter element 8c is z. B. formed by holding plate 23 made of steel, which is adhered to the inside 6 b of the cover 6. In the embodiment, the plate 23 is formed by an angle with an upright inside leg 23a, which fulfills a positioning function to be described later.

Um zu gewährleisten, daß die vorhandenen Halteplatten 23 von außen nicht sichtbar sind, ist zwischen der Halteplatte 23 und der Abdeckung 6 eine besondere feste Schicht 24, insbesondere aus Keramik, vorgesehen, die fest mit der Abdeckung 6 verbunden ist und beim Ausführungsbeispiel nach außen hin weiß und nach innen hin schwarz ist. In einem solchen Fall sind die Halteplatten 23 auf die Schicht 24 geklebt. Die Schicht 24 erstreckt sich vorzugsweise über den gesamten Umfang der Innenseite 6b und sie bildet somit einen Ringstreifen, hier viereckiger Form.To ensure that the existing holding plates 23 are not visible from the outside, between the holding plate 23 and the cover 6, a special solid layer 24, in particular made of ceramic, is provided, which is firmly connected to the cover 6 and in the embodiment to the outside white and black inside. In such a case, the holding plates 23 are on the layer 24th glued. The layer 24 preferably extends over the entire circumference of the inner side 6 b and thus forms a ring strip, here quadrangular shape.

Die Schicht 24 wird beim Herstellen der Abdeckung 6 bzw. Scheibe 6a aufgebracht und intensiv und unlösbar verbunden. Sie befindet sich somit vorgefertigt an der Abdeckung 6. Aufgrund der Ringform können auch andere noch zu beschreibende Teile der Leuchte 1 an der Abdeckung stabil angeklebt werden.The layer 24 is applied during manufacture of the cover 6 or disk 6a and connected intensively and permanently. It is thus prefabricated on the cover 6. Due to the ring shape, other parts of the lamp 1 to be described can be stably glued to the cover.

Zwischen der Gehäusewanne 2 und der Abdeckung 6 ist wenigstens eine Zentriervorrichtung 25 angeordnet, die die Abdeckung 6 bezüglich der Gehäusewanne 2 zentriert. Aus konstruktiven Gründen sind vorzugsweise zwei Zentriervorrichtungen 25 einander gegenüberliegend im Randbereich der Leuchte 1 vorgesehen, die spiegelbildlich zueinander angeordnet und ausgebildet sind, so daß nur eine Zentriervorrichtung 25 beschrieben zu werden braucht.Between the housing pan 2 and the cover 6, at least one centering device 25 is arranged, which centers the cover 6 with respect to the housing pan 2. For design reasons, two centering devices 25 are preferably provided opposite each other in the edge region of the lamp 1, which are arranged and constructed in mirror image to each other, so that only one centering device 25 needs to be described.

Die Zentriervorrichtung 25 weist eine Zentrierausnehmung 25a und einen darin mit geringem Bewegungsspiel einsteckbaren Zentrierzapfen 25b auf. Beim Ausführungsbeispiel ist der vorzugsweise angespitzte Zentrierzapfen 25b auf der Innenseite der Abdeckung 6 befestigt, und die Zentrierausnehmung 24a ist in einem Anbauteil der Gehäusewanne 2 angeordnet, z. B. im Randstreifen 2h oder in einer darauf aufgesetzten Zentrierplatte 26. Aufgrund der Ringform der Schicht 24 läßt sich auch der Zentrierstift 25b an der Innenseite 6b stabil und sicher auf der Schicht 24 festkleben. Hierzu kann er zur Vergrößerung der Klebefläche einen Kopfflansch 25c aufweisen. Beim Ausführungsbeispiel sind zwei Zentriervorrichtungen 25 einander gegenüberliegend in den Stirnendbereichen der Leuchte 1 vorzugsweise mittig angeordnet.The centering device 25 has a centering recess 25a and a centering pin 25b which can be inserted therein with little play of movement. In the exemplary embodiment, the preferably pointed centering pin 25 b is fixed on the inside of the cover 6, and the centering recess 24 a is arranged in an attachment of the housing pan 2, z. Due to the ring shape of the layer 24 can also be the centering pin 25b on the inside 6b stable and secure on the layer 24 sticking. For this purpose, he may have a head flange 25c to increase the adhesive surface. In the embodiment, two centering devices 25 are preferably arranged opposite one another in the front end regions of the lamp 1, preferably centrally.

Zur Halterung der wenigstens einen und vorzugsweise länglichen sowie insbesondere durch eine Leuchtstoffröhre gebildeten Lichtquelle 5 sind in der Gehäusewanne 2 in den einander gegenüberliegenden, hier stirnseitigen, Endbereichen jeweils ein Fassungsträger 27 angeordnet, der an der Bodenwand 2a oder an den einander gegenüberliegend angeordneten Geräteträgern 14 bzw. deren Trägerschenkel 14b bzw. 14d befestigt sein kann. Vorzugsweise sind am Fassungsträger 27 nicht nur eine Fassung 28, sondern mehrere Fassungen 28 nebeneinander angeordnet, wobei eine Fassung 28 vorzugsweise mittig angeordnet ist. Beim Ausführungsbeispiel sind auf beiden Seiten von dieser mittigen Fassung 28 drei weitere Fassungen 28a bis 28f angeordnet.In order to hold the at least one and preferably elongated light source 5, in particular formed by a fluorescent tube 5, in each case a socket carrier 27 is arranged in the housing tub 2 in the housing pan 2, which is located on the bottom wall 2a or on the device carriers 14 arranged opposite one another . whose support legs 14b and 14d may be attached. Preferably, not only a socket 28, but several versions 28 are arranged side by side on the holder support 27, wherein a socket 28 is preferably arranged centrally. In the embodiment, two further sockets 28a to 28f are arranged on both sides of this central frame 28.

Zur Reflexion des von der wenigstens einen Lichtquelle 5 abgestrahlten Lichtes zur Wannenöffnung 7 hin ist in der Gehäusewanne 2 wenigstens ein Reflektor 29 angeordnet, der durch die Wannenöffnung 7 hindurch einbaubar ist und durch eine Steckfassung 31 in der Gehäusewanne 2 positioniert ist. Der Reflektor 29 ist z. B. domförmig ausgebildet mit einander gegenüberliegenden Reflektorseitenwänden 29a, die konkav gekrümmte Reflexionsflächen 29c aufweisen und sich bei einer vorliegenden länglichen Leuchte 1 in der Längsrichtung gerade erstrecken.In order to reflect the light emitted by the at least one light source 5 towards the trough opening 7, at least one reflector 29 is arranged in the housing trough 2, which can be installed through the trough opening 7 and is positioned in the housing trough 2 by a jack 31. The reflector 29 is z. B. dome-shaped with opposing reflector side walls 29 a, the concave curved reflecting surfaces 29 c have and extend straight in a present elongated lamp 1 in the longitudinal direction.

Die Steckfassung 31 kann durch formschlüssig mit den Reflektorseitenwänden 29a zusammenwirkende Positionierelemente gebildet sein. Beim Ausführungsbeispiel weisen die Reflektorseitenwände 29a in ihren freien Rändern einen nach innen umgebogenen Flansch 29d auf. In den davon innenseitig gebildeten Freiraum fassen Positionierteile 31a formschlüssig ein, die vorzugsweise durch die freien Enden von Positionierstegen 19a angeformt sind, die ebenfalls durch einen winkelförmigen Einschnitt 20a aus dem Trägerschenkel 14a ausgeschnitten und nach innen als vertikale Stege umgebogen sind.The jack 31 may be formed by positively cooperating with the reflector side walls 29a positioning. In the exemplary embodiment, the reflector side walls 29a in their free edges on an inwardly bent flange 29d. Positioning parts 31a, which are preferably formed by the free ends of positioning webs 19a, which are likewise cut out of support leg 14a by an angular cut 20a and bent inwards as vertical webs, engage in the free space formed on the inside thereof.

Um unterschiedliche Lichtabstrahlungen zu erhalten, sind vorzugsweise zwei entsprechend unterschiedliche Reflektoren 29 der Leuchte 1 zugeordnet, die wahlweise einbaubar sind. Vorzugsweise handelt es sich um einen symmetrischen Reflektor 29 mit symmetrischen Reflektorseitenwänden 29a und einen asymmetrischen Reflektor 29 mit asymmetrischen Reflektorseitenwänden 29b, die zur Verdeutlichung des Sachverhaltes in Fig. 2 beide dargestellt sind. Wie die Zeichnung deutlich erkennen läßt, sind die Krümmungen der einander gegenüberliegenden Reflektorseitenwände 29b des asymmetrischen Reflektors 29b unterschiedlich. Auf der einen Seite ist die Krümmung flacher und auf der anderen Seite stärker. Um die Asymmetrie nach beiden Seiten zu verdeutlichen, sind ein Reflektor 29 mit einer nach links und ein Reflektor 29 mit einer Asymmetrie nach rechts dargestellt. In Fig. 1 ist der Reflektor 29 nicht dargestellt.In order to obtain different light emissions, preferably two correspondingly different reflectors 29 of the luminaire 1 are assigned, which can be installed optionally. Preferably, it is a symmetrical reflector 29 with symmetrical reflector side walls 29a and an asymmetric reflector 29 with asymmetric reflector side walls 29b, which to clarify the facts in Fig. 2 both are shown. As the drawing clearly shows, the curvatures of the opposite reflector side walls 29b of the asymmetric reflector 29b are different. On the one hand the curvature is flatter and on the other hand stronger. To illustrate the asymmetry on both sides, a reflector 29 are shown with one to the left and a reflector 29 with an asymmetry to the right. In Fig. 1 the reflector 29 is not shown.

Darüber hinaus können andeutungsweise dargestellte Raster 32 vorgesehen sein, die sich in an sich bekannter Weise quer zur Längsrichtung der Leuchte 1 erstrecken. Der bzw. die Reflektoren 29 können mit den Rastern 32 eine Baueinheit bilden.In addition, hinted grid 32 may be provided which extend in a conventional manner transverse to the longitudinal direction of the lamp 1. The reflector or reflectors 29 can form a structural unit with the grids 32.

Durch eine unterschiedliche Bestückung der Fassungen 28 bis 28f jeweils mit einer mittigen oder einer oder mehreren einseitig angeordneten Lichtquellen 5 läßt sich die asymmetrische Lichtabstrahlung zum einen bezüglich der Lichtdichte und zum anderen auch bezüglich der Asymmetrie verändern bzw. einstellen.By a different equipping of the sockets 28 to 28f each with a central or one or more light sources 5 arranged on one side, the asymmetrical light emission can be changed or adjusted with respect to the light density and also with respect to the asymmetry.

Bei der Leuchte 1 kann es sich um eine an eine Decke oder Wand direkt anbaubare Anbauleuchte oder eine abhängbare Leuchte 1 handeln. Für den letzteren Fall sind in den Eckenbereichen der Bodenwand 2a vier Aufhängelemente 33 vorgesehen, die mit Seilen, Ketten oder Pendeln zur Aufhängung an einer Decke verbindbar sind.The luminaire 1 may be a surface mounted luminaire or a suspended luminaire 1 that can be directly attached to a ceiling or wall. For the latter case, four suspension elements 33 are provided in the corner regions of the bottom wall 2a, which can be connected to cables, chains or pendulums for suspension on a ceiling.

Um zu gewährleisten, daß das von der wenigstens einen Lichtquelle 5 abgestrahlte Licht im wesentlichten konzentriert von der Leuchte 1 nach unten abgestrahlt wird oder zumindest nicht nach außen hin blendet, kann an der Innenseite 6b der Scheibe 6a ein flaches Lichtbeeinflussungsmittel 34, z. B. eine Streufolie, eine Mikroprismenscheibe oder ein Raster, angeordnet sein. Zur Positionierung oder Befestigung des Lichtbeeinflussungsmittels 34 an der Innenseite 6b sind Positioniermittel 35, z. B. Profilwinkel 35a, vorgesehen, die z. B. auf der Innenseite 6b angeordnet und positioniert sind, z. B. auf der Schicht 24 geklebt sind oder an den Schenkeln 23a befestigt sind, z. B. durch Schrauben oder Aufklipsen.In order to ensure that the light emitted by the at least one light source 5 is substantially radiated downwards from the luminaire 1 or at least does not fade outwards, a flat light influencing means 34, e.g. As a scattering film, a micro prismatic disk or a grid, be arranged. For positioning or attachment of the light influencing means 34 on the inner side 6b are positioning means 35, z. B. profile angle 35 a, provided z. B. are arranged and positioned on the inside 6b, z. B. are glued to the layer 24 or attached to the legs 23 a, z. B. by screwing or clipping on.

Um zu vermeiden, daß die Abdeckung 6 bzw. die Scheibe 6a nach dem Lösen herunterfällt, ist eine Abhängsicherung 36 mit wenigstens einem Abhängelement 36a vorgesehen, die ein Herunterfallen über eine Abhängposition hinaus verhindert. Beim Ausführungsbeispiel sind zwei flexible Bänder 36, z. B. Seile, vorgesehen, die in einem Abstand voneinander angeordnet sind und durch Verbindungselemente 37a, 37b mit der Abdeckung 6 bzw. der Scheibe 6a und der Gehäusewanne 2 verbunden sind und so lang bemessen sind, daß die Abdeckung 6 in einem geringen Abstand von der Gehäusewand 2 hängen bleibt. Die Bänder und vorzugsweise lösbaren Befestigungselemente sind vorzugsweise im Randbereich einer Breitseite der Gehäusewanne 2 und der Abdeckung 6 bzw. Scheibe 2a angeordnet. Die Verbindungselemente 37b sind vorzugsweise an der Innenseite 6b der Abdeckung 6 bzw.
