Description

Die Erfindung bezieht sich auf eine Leuchte nach dem Oberbegriff des Anspruches 1.The invention relates to a luminaire according to the preamble of claim 1.

Übliche Leuchten zur Beleuchtung eines Raumes kann man hinsichtlich ihrer Position zu einem sie tragenden Träger in zwei Kategorien einteilen. Bei der ersten Kategorie ist die Leuchte mit einem gegebenenfalls vorhandenen und den Reflektor aufnehmenden Gehäuse an einem Leuchtenträger, z.B. an der Decke oder einer Wand des Raumes, oder an einem im Raum angeordneten Leuchtenträger angebaut. Dabei kann die Leuchte als Anbauleuchte unmittelbar am Leuchtenträger oder in einem Abstand davon gehalten sein, z.B. mittels wenigstens eines langgestreckten Aufhängelements, wie eines oder mehrerer Seile, Ketten oder Pendel. Bei der zweiten Kategorie ist die Leuchte als Einbauleuchte wenigstens teilweise in eine Einbauöffnung im Leuchtenträger, z.B. in die Decke oder die Wand des Raumes, eingebaut.Conventional luminaires for illuminating a room can be divided into two categories with regard to their position relative to a support carrying them. In the first category, the luminaire is provided with an optional housing and the reflector housing on a light carrier, e.g. on the ceiling or a wall of the room, or attached to a light carrier arranged in the room. In this case, the luminaire may be kept as a surface-mounted luminaire directly on the luminaire support or at a distance therefrom, e.g. by means of at least one elongated suspension element, such as one or more cables, chains or pendulums. In the second category, the luminaire is as a recessed luminaire at least partially in a mounting hole in the light carrier, e.g. built into the ceiling or wall of the room.

Eine Leuchte der eingangs angegebenen Art ist z.B. in der DE 43 44 376 A1 oder der DE 43 44 431 A1 beschrieben und zwar jeweils als Einbauleuchte. Bei diesen bekannten Ausgestaltungen ist der Reflektor jeweils durch ein Grundgestell am Leuchtenträger, nämlich der Decke eines Raumes befestigbar, wobei das Grundgestell an seinem in die Abstrahlrichtung weisenden Ende ein flanschförmiges Randteil zum Abdecken der Fuge zwischen dem Einbauöffnungsrand aufweist. Der Grundrahmen ist mittels besonderen Halteteilen am Einbauöffnungsrand der Decke befestigbar und bildet somit ein erstes Haltemittel zum Halten der Leuchte am Leuchtenträger. Ein Lampenhalter oder Fassungsträger für wenigstens eine Lampe ist in einer Position angeordnet, in der er einer Ausnehmung im Reflektor außen gegenüberliegt und durch zweite Haltemittel mit dem Grundrahmen lösbar verbunden ist. Bei dieser bekannten Ausgestaltung ist ein großer Herstellungsaufwand vorgegeben, der auch zu einer handhabungsaufwendigen und zeitaufwendigen Montage bzw. Demontage führt.A luminaire of the type specified in the example is in the DE 43 44 376 A1 or the DE 43 44 431 A1 each described as recessed luminaire. In these known embodiments, the reflector is in each case fastened by a base frame on the light carrier, namely the ceiling of a room, wherein the base frame has a flange-shaped edge part for covering the gap between the installation opening edge at its end pointing in the emission direction. The base frame is fastened by means of special holding parts on the installation opening edge of the ceiling and thus forms a first holding means for holding the lamp on the light carrier. A lamp holder or socket carrier for at least one lamp is arranged in a position in which it is opposite to a recess in the reflector outside and is releasably connected by second holding means with the base frame. In this known embodiment, a large manufacturing effort is given, which also leads to a handling-consuming and time-consuming assembly and disassembly.

Eine Leuchte der eingangs angegebenen Art ist auch in der WO 98/03817 beschrieben.A lamp of the type specified is also in the WO 98/03817 described.

Der Erfindung liegt die Aufgabe zugrunde, eine Leuchte der eingangs angegebenen Art zu vereinfachen. Insbesondere soll die Halterung des Lampenhalters verbessert werden.The invention has for its object to simplify a lamp of the type specified. In particular, the holder of the lamp holder is to be improved.

Diese Aufgabe wird durch die Merkmale des Anspruches 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 Ausgestaltung ist der Lampenhalter durch direkte Verbindung mit der Außenseite des Reflektors an diesem befestigt. Hierdurch ist es möglich, den Fassungsträger direkt an der Außenseite des Reflektors zu halten. Im Vergleich mit der gattungsgemäßen Ausgestaltung kann somit ein Grundgestell alsIn the embodiment according to the invention, the lamp holder is fastened by direct connection to the outside of the reflector on this. This makes it possible to hold the socket carrier directly on the outside of the reflector. In comparison with the generic embodiment can thus be a base frame as

mittelbares Halteteil zwischen dem Fassungsträger und dem Reflektor entfallen. Folglich läßt sich die erfindungsgemäße Leuchte einfacher ausgestalten, wobei Herstellungsaufwand, Material, Gewicht, Montage- bzw. Demontageaufwand und Kosten eingespart werden können und eine kleine Bauweise erreicht wird.indirect holding part between the socket carrier and the reflector omitted. Consequently, the lamp according to the invention can be made simpler, manufacturing cost, material, weight, assembly and disassembly costs and costs can be saved and a small design is achieved.

In den Ansprüchen sind Merkmale enthalten, die die Bauweise und Herstellung weiter vereinfachen und die Montage bzw. Demontage weiter erleichtern. Dabei ist es möglich, den Lampenhalter unlösbar am Reflektor zu befestigen, wobei diesbezügliche Montage- bzw. Demontagemaßnahme entfallen. Durch eine lösbare Befestigung des Lampenhalters läßt sich eine sperrige Bauweise des Reflektors vermeiden. In diesem Falle ist es vorteilhaft, zwischen dem Reflektor und dem Lampenhalter eine Steckverbindung, anzuordnen, wodurch eine handhabungsfreundliche und schnelle Montage bzw. Demontage gewährleistet ist. Es ist z.B. an der Baustelle möglich, den Lampenhalter in einfacher Weise möglichst ohne den Gebrauch von Werkzeugen am Reflektor zu montieren bzw. zu demontieren. Dabei ist es im weiteren vorteilhaft, die Steckverbindung so auszubilden, daß die Einsteckbewegung des Lampenhalters in die Einsteckposition etwa vertikal bzw. nach unten gerichtet ist. Bei einer solchen Ausgestaltung ist der Lampenhalter aufgrund seiner Schwerkraft daran gehindert, sich aus der Steckfassung herauszubewegen. In Fällen, in denen die Einsteckbewegung unter Berücksichtigung des Einbauzustandes der Leuchte nicht nach unten gerichtet ist, ist es vorteilhaft, zwischen dem Reflektor und dem Lampenhalter eine Positioniervorrichtung zum lösbaren Positionieren des Lampenhalters in der eingesteckten Stellung vorzusehen, um unbeabsichtigte Bewegungen des Lampenhalters aus seiner Einsteckstellung heraus zu vermeiden. Eine solche Positioniervorrichtung eignet sich für alle Einbaupositionen und auch dann, wenn die Einsteckbewegung des Lampenhalters nach unten gerichtet ist. Hierdurch wird z.B. vermieden, daß der Lampenhalter durch Montage- bzw. Demontagemaßnahmen aus seiner Einsteckstellung herausbewegt wird, z.B. beim Einstecken einer Lampen in eine Fassung des Lampenhalters. Im übrigen werden Merkmale erreicht, die zu einer kleinen und/oder kostengünstig hergestellbaren Bauweise der Leuchte bzw. ihrer Teile führen.In the claims are included features that further simplify the design and manufacture and further facilitate assembly and disassembly. It is possible to attach the lamp holder inextricably attached to the reflector, with respect related assembly or disassembly action omitted. By releasably securing the lamp holder, a bulky design of the reflector can be avoided. In this case, it is advantageous to arrange a connector between the reflector and the lamp holder, whereby a handling-friendly and fast assembly and disassembly is guaranteed. It is e.g. At the construction site possible to mount the lamp holder in a simple manner possible without the use of tools on the reflector or dismantle. In this case, it is further advantageous to design the connector so that the insertion movement of the lamp holder is directed in the insertion about vertical or downward. In such an embodiment, the lamp holder is prevented due to its gravity from moving out of the socket. In cases where the insertion movement is not directed downward in consideration of the installation condition of the luminaire, it is advantageous to provide a positioning device between the reflector and the lamp holder for removably positioning the lamp holder in the inserted position to prevent inadvertent movement of the lamp holder from its insertion position to avoid out. Such a positioning device is suitable for all mounting positions and also when the insertion movement of the lamp holder is directed downward. This is e.g. avoided that the lamp holder is moved out of its insertion position by assembly or disassembly measures, e.g. when inserting a lamp into a socket of the lamp holder. Moreover, features are achieved that lead to a small and / or cost-manufacturable construction of the lamp or its parts.

Die in ihrer Gesamtheit mit 1 bezeichnete Leuchte ist eine Einbauleuchte, die in eine Einbauöffnung 2 einer Einbauwand 3 eingebaut ist, bei der es sich um eine Decke oder eine Wand eines mit der Leuchte 1 zu beleuchtenden Raumes 4 handeln kann. Hierzu dienen nicht dargestellte erste Haltemittel, die mit dem Einbauöffnungsrand zusammenwirken.The luminaire designated in its entirety by 1 is a recessed luminaire which is installed in an installation opening 2 of a built-in wall 3, which may be a ceiling or a wall of a room 4 to be illuminated by the luminaire 1. Serve for this purpose, not shown first holding means which cooperate with the installation opening edge.

Die Hauptteile der Leuchte 1 sind ein domförmiger Reflektor 5 und ein Lichtquellenträger zur Aufnahme wenigstens einer Lichtquelle. Aus Vereinfachungsgründen werden in der weiteren Beschreibung im Hinblick auf das Ausführungsbeispiel der Lichtquellenträger mit Fassungsträger 6 und die Lichtquelle mit Lampe 7 bezeichnet, bei der es sich um wenigstens eine Leuchtstofflampe handeln kann. Außerdem sind vorgesehen ein Montagering 8 zum Abdecken eines Einbauspaltes zwischen der Leuchte 1 und dem Rand der Einbauöffnung 2 und Betriebsmittel 9 für die Leuchte 1, bei denen es sich z.B. um ein Vorschaltgerät und/oder elektrische Anschlußelemente handeln kann, die z.B. in einem Betriebsmittelgehäuse 11 angeordnet sein können und durch ein elektrisches Kabel 12 mit dem Fassungsträger 6 verbindbar sind oder verbunden sein können.The main parts of the luminaire 1 are a dome-shaped reflector 5 and a light source carrier for receiving at least one light source. For reasons of simplification, in the further description with regard to the exemplary embodiment, the light source carrier with socket carrier 6 and the light source with lamp 7, which may be at least one fluorescent lamp, are designated. There is also provided a mounting ring 8 for covering a mounting gap between the luminaire 1 and the edge of the mounting hole 2 and luminaire 1 operating means 9 which may be e.g. may be a ballast and / or electrical connection elements, e.g. can be arranged in a resource housing 11 and are connected by an electrical cable 12 with the socket carrier 6 or can be connected.

Beim vorliegenden Ausführungsbeispiel weist die Leuchte 1 bzw. ihr Reflektor 5 eine runde Querschnittsform auf, wobei sich der Querschnitt rechtwinklig zur sich in den Raum 4 hinein erstreckenden Hauptabstrahlrichtung 13 verläuft. Die Erfindung ist jedoch nicht auf eine runde Querschnittsform beschränkt. Im Rahmen der Erfindung kann die Querschnittsform auch von einer runden Form abweichend sein, z.B eine viereckige oder quadratische Querschnittsform sein. Der Reflektor 5 besteht aus einer domförmigen Reflektorwand 14 mit einem in die Hauptabstrahlrichtung 13 divergierenden Umfangswandabschnitt, der in einen gewölbten Deckenwandabschnitt übergeht. Am Rand des Umfangswandabschnitts kann ein Außenflansch 15 angeformt sein. Die Innenfläche des Umfangswandsabschnitts und des Deckenwandabschnitts ist als Reflexionsfläche 16 ausgebildet. Hierzu kann die betreffende Innenfläche der Reflektorwand 14 entsprechend behandelt sein oder mit einer Reflexionsschicht beschichtet sein. Zur Positionierung der Lampe 7 im vorzugsweise oberen Bereich des Innenraums 17 des Reflektors 5 ist im Umfangswandabschnitt der Reflektorwand 14 ein Durchführungsloch 18 vorgesehen, das beim vorliegenden Ausführungsbeispiel eine im wesentlichen viereckige Form hat.In the present exemplary embodiment, the luminaire 1 or its reflector 5 has a round cross-sectional shape, the cross-section extending at right angles to the main emission direction 13 extending into the space 4. However, the invention is not limited to a round cross-sectional shape. In the context of the invention, the cross-sectional shape can also be deviating from a round shape, for example be a quadrangular or square cross-sectional shape. The reflector 5 consists of a dome-shaped reflector wall 14 with a diverging in the main emission direction 13 peripheral wall portion, which merges into a curved ceiling wall portion. At the edge of the peripheral wall portion, an outer flange 15 may be formed. The inner surface of the peripheral wall portion and the ceiling wall portion is formed as a reflection surface 16. For this purpose, the relevant inner surface of the reflector wall 14 may be treated accordingly or coated with a reflective layer. For positioning the lamp 7 in the preferably upper region of the interior 17 of the reflector 5, a feedthrough hole 18 is provided in the peripheral wall portion of the reflector wall 14, which in the present embodiment has a substantially quadrangular shape.

Der Montagering 8 ist mit einem sich koaxial zu seiner Mittelachse erstreckenden Hülsenschenkel 8a und einem davon nach außen abstehenden Flanschschenkel 8b im Querschnitt winkelförmig geformt. Der Montagering 8 kann noch zu beschreibende Befestigungsmittel aufweisen, mit denen er am freien Rand des Reflektors 5 und/oder am Rand der Einbauöffnung 2 lösbar befestigbar ist. Es ist der Zweck des Montagerings 8, einen in der Montagestellung der Leuchte 1 vorhandenen Spalt zwischen dem Rand der Einbauöffnung 2 und dem Reflektor 5 abzudecken. Er kann auf dem Umfang verteilt angeordnete und von ihm nach oben ragende nicht dargestellte Haltefinger aufweisen, die zu einer lösbaren Befestigung am Einbauöffnungsrand diesen lösbar hintergreifen. Außerdem kann der Montagering 8 den Reflektor 5 tragen und somit ein Teil des bereits erwähnten ersten Haltemittels zum Halten des Reflektors 5 in der Einbauöffnung 2 bilden. Es ist auch möglich, daß der Reflektor 5 außen an seinem unteren Rand nach oben ragende Haltefinger für ein lösbares Hintergreifen des Einbauöffnungsrandes aufweist.The mounting ring 8 is angularly shaped in cross-section with a sleeve leg 8a extending coaxially with its center axis and a flange leg 8b projecting outward therefrom. The mounting ring 8 may still have to be described fastening means with which it is releasably attachable to the free edge of the reflector 5 and / or at the edge of the mounting hole 2. It is the purpose of the mounting ring 8 to cover a gap existing in the mounting position of the luminaire 1 between the edge of the mounting opening 2 and the reflector 5. He may distributed on the circumference arranged and have upwardly projecting from him holding fingers not shown, which engage behind a releasable attachment to the installation opening edge releasably. In addition, the mounting ring 8 can carry the reflector 5 and thus form part of the already mentioned first holding means for holding the reflector 5 in the mounting opening 2. It is also possible that the reflector 5 has outside at its lower edge upwardly projecting retaining fingers for releasably engaging behind the installation opening edge.

Der Montagering 8 kann auch an seiner Innenmantelfläche einen umlaufenden Innenflansch 8c oder mehrere auf dem Umfang verteilt angeordnete Innenansätze vorzugsweise einteilig angeformt aufweisen.The mounting ring 8 may also have on its inner circumferential surface a circumferential inner flange 8c or more distributed on the circumference arranged inner lugs preferably integrally formed.

Der Fassungsträger 6 ist durch an ihm ausgebildete zweite Haltemittel 22 und mit diesen korrespondierende dritte Haltemittel 23, die von außen zugänglich am Reflektor 5 angeordnet sind, unmittelbar am Reflektor 5 positionierbar. Die zweiten und dritten Haltemittel 22,23 bilden eine Steckverbindung 24, die es ermöglicht, den Fassungsträger 6 handhabungsfreundlich und schnell am Reflektor 5 zu montieren bzw. zu demontieren. Die zweiten Haltemittel 22 und/oder ihre Tragteile sind vorzugsweise einteilig am Fassungsträger 6 angeformt. Entsprechend sind auch die dritten Haltemittel 23 und/oder ihre Tragteile vorzugsweise einteilig am Reflektor 5 angeformt. Hierdurch ist eine rationelle und kostengünstige Fertigung möglich. Es ist vorteilhaft, die Haltemittel 22,23 so auszubilden, daß sie durch eine etwa in die Hauptabstrahlrichtung 13 verlaufende Bewegung des Fassungsträgers 6 in Halteeingriff bringbar sind und durch eine umgekehrte Bewegung des Fassungsträgers 6 voneinander lösbar sind. Hierzu kann eine Führung mit wenigstens einem Führungsteil dienen, das in der Führung bis zu einer Endstellung verschiebbar, jedoch quer zur Führung formschlüssig in der Führung gehalten ist.The socket carrier 6 can be positioned directly on the reflector 5 by means of second holding means 22 formed thereon and by means of these third holding means 23, which are arranged on the reflector 5 accessible from the outside. The second and third holding means 22,23 form a plug-in connection 24, which makes it possible to assemble and disassemble the socket carrier 6 in a manner that is easy to handle and fast on the reflector 5. The second holding means 22 and / or their supporting parts are preferably integrally formed on the holder carrier 6. Accordingly, the third holding means 23 and / or their supporting parts are preferably integrally formed on the reflector 5. As a result, a rational and cost-effective production is possible. It is advantageous to design the holding means 22, 23 in such a way that they can be brought into holding engagement by a movement of the holder carrier 6 approximately in the main emission direction 13 and can be released from one another by a reverse movement of the holder carrier 6. For this purpose, a guide can be used with at least one guide part, which is held in the guide up to an end position displaceable, but held transversely to the guide in a form-fitting manner in the guide.

Beim vorliegenden Ausführungsbeispiel sind die dritten Haltemittel 23 durch einander gegenüberliegend angeordnete Nuten 23a in zu beiden Seiten des Durchführungslochs 18 angeordneten Stegwänden 23b gebildet, die sich im wesentlichen parallel zueinander und im wesentlichen parallel zur Hauptabstrahlrichtung 13 erstrecken und vorzugsweise einteilig an der Reflektorwand 14 befestigt sind, vorzugsweise angeformt sind. Der Fassungsträger 6 weist voneinander weg abstehende Führungsstege 22a auf, die mit Gleitspiel in die Führungsnuten 23a passen. Die durch den Pfeil 25 verdeutlichte Einsteckbewegung kann durch die Enden der Führungsnuten 23a und/oder durch eine Stufenfläche 25a an der Reflektorwand 14 begrenzt sein. Der Fassungsträger 6 kann ein quaderförmiges Fassungsgehäuse 26 aufweisen, in dem eine oder mehrere nur in Fig. 3 dargestellte Fassungen 26a in einem Fassungskörper 26b angeordnet sind, die von der dem Reflektor 5 zugewandten Stirnseite des Gehäuses 26 her mit einer oder mehreren Lampen 7, hier zwei Stück, zugänglich sind. In den Figuren sind die sich quer zur offenen Stirnseite erstreckenden Seitenwände 26c, eine Deckenwand 26d und eine Rückwand 26e des Fassungsgehäuses 26 sichtbar. Die Deckenwand 26d ist vorzugsweise über die Stirnseite des Fassungsgehäuses 26 verlängert, wobei ihre Stirnkante 26f sich bis zum Umfangswandabschnitt des Reflektors 5 erstreckt und entsprechend dessen Form konkav geformt ist. Hierdurch wird ein sich oberhalb des Durchführungslochs 18 aufgrund der Divergenz des Umfangswandsabschnitts ergebender Freiraum abgedeckt, wobei die Verlängerung der Deckenwand 26c einen Schutz gegen Staubbefall der wenigestens einen Fassung bzw. Lampe 7 bildet.In the present embodiment, the third holding means 23 are formed by oppositely disposed grooves 23 a in arranged on both sides of the feedthrough hole 18 web walls 23 b, which are substantially parallel to each other and extend substantially parallel to the main emission direction 13 and are preferably integrally attached to the reflector wall 14, preferably formed. The socket carrier 6 has guide webs 22a which project away from one another and which fit with sliding play into the guide grooves 23a. The insertion movement illustrated by the arrow 25 can be limited by the ends of the guide grooves 23a and / or by a step surface 25a on the reflector wall 14. The socket carrier 6 may have a cuboid socket housing 26, in which one or more only in Fig. 3 shown sockets 26a are arranged in a socket body 26b, which are accessible from the reflector 5 facing the front side of the housing 26 forth with one or more lamps 7, here two pieces. In the figures, the transverse to the open end side extending side walls 26c, a ceiling wall 26d and a rear wall 26e of the socket housing 26 are visible. The ceiling wall 26d is preferably extended beyond the end face of the socket housing 26, with its end edge 26f extending to the peripheral wall portion of the reflector 5 and concavely shaped according to its shape. As a result, a free space which results above the leadthrough hole 18 due to the divergence of the circumferential wall section is covered, wherein the extension of the ceiling wall 26c forms a protection against dust attack of at least one socket or lamp 7.

Die Steckverbindung 24 ermöglicht ein handhabungsfreundliches und schnelles Montieren bzw. Demontieren des Fassungsträgers 6 am Reflektor 5, nämlich durch einfaches Einstecken der zweiten Haltemittel 22 in die dritten Haltemittel 23. Dies kann vor dem Einbau des Reflektors 5 in die Einbauöffnung 2 erfolgen, wobei der soweit vormontiere Reflektor 5 mit dem Betriebsmittelgehäuse 11 und dem Fassungsträger 6 in einer gekippten Position in die Einbauöffnung 2 einsteckbar und dann in seine Normalstellung gekippt werden kann. Eine Möglichkeit zur Positionierung des Reflektors 5 an der Einbauwand 5 kann - wie vorbeschrieben - durch den Montagering 8 oder durch am Reflektor 5 angeordnete Haltemittel erfolgen. Es ist von Vorteil, den Fassungsträger 6 in seiner in die Steckfassung 24 eingesteckten Position durch wenigstens ein Positionierelement lösbar zu positionieren, vorzugsweise durch eine Klemm- oder Verrastungsvorrichtung, die lösbar oder vorzugsweise zu ihrer Lösung manuell überdrückbar sind. Eine Klemmvorrichtung kann z.B. dadurch gebildet sein, daß im Endbereich der Steckfassung seitlich wenigstens ein Klemmnocken 27 angeordnet, insbesondere angeformt ist, der das zugehörige Haltemittel 22 in der Einsteckendstellung klemmt und somit arretiert. Zum Lösen ist diese Klemmung vorzugsweise manuell überdrückbar.The connector 24 allows handling friendly and fast mounting or dismounting of the socket carrier 6 on the reflector 5, namely by simply inserting the second holding means 22 in the third holding means 23. This can be done before installing the reflector 5 in the mounting hole 2, the extent preassembled reflector 5 with the equipment housing 11 and the socket carrier 6 in a tilted position in the mounting hole 2 can be inserted and then tilted into its normal position. One possibility for positioning the reflector 5 on the mounting wall 5 can - as previously described - done by the mounting ring 8 or arranged on the reflector 5 holding means. It is advantageous to releasably position the socket carrier 6 in its inserted into the socket 24 position by at least one positioning, preferably by a clamping or latching device, which are detachable or preferably manually überdrückbar to solve it. A clamping device may be formed, for example, in that in the end region of the jack laterally at least one clamping cam 27 is arranged, in particular formed, which clamps the associated holding means 22 in the Einsteckendstellung and thus locked. To release this clamp is preferably manually überdrückbar.

Bei allen Ausgestaltungen kann der Montagering 8 auch als Träger zur lösbaren Befestigung von Zubehörteilen, z.B. für eine den Innenraum 17 des Reflektors 5 abdeckende Scheibe dienen. Dies ist aus Vereinfachungsgründen nicht dargestellt.In all embodiments, the mounting ring 8 may also be used as a carrier for releasable attachment of accessories, e.g. serve for a the interior 17 of the reflector 5 covering disc. This is not shown for reasons of simplification.

Der Reflektor 5, der Fassungsträger 6 und/oder der Montagering 8 bestehen vorzugsweise aus einem Material, das durch Spritzgießen (Spritzguß) oder Druckgießen (Druckguß) herstellbar ist, z.B. Aluminium oder Kunststoff, wobei die Teile mit ihren Anbauteilen jeweils einstückig geformt sind und einfach und kostengünstig durch Spritzgießen hergestellt werden können.The reflector 5, the socket carrier 6 and / or the mounting ring 8 are preferably made of a material which can be produced by injection molding (injection molding) or die casting (die casting), e.g. Aluminum or plastic, the parts are each integrally formed with their attachments and can be easily and inexpensively produced by injection molding.

Die Lampen 7 können nach dem Anmontieren des Fassungsträgers 6 an den Reflektor 5 von dessen Innenraum 17 montiert, d.h., in die Fassungen 26a eingesetzt, werden.The lamps 7 may be mounted to the reflector 5 from the interior 17 thereof after mounting the socket carrier 6, i.e. inserted into the sockets 26a.
