Description

Die Erfindung betrifft ein Leuchtstofflampen-Set, bestehend aus einer stabförmigen Leuchtstofflampe und einem langgestreckten, rinnenförmigen Trägerprofil, das in seiner Breite nur wenig größer ist als der Durchmesser des Entladungsgefäßes. Die Leuchtstofflampe ist über dem Trägerprofil parallel zu diesem und ohne Berührung mit diesem angeordnet und in Fassungsteilen kontaktierend gehaltert, wobei diese mittels an ihnen angeordneter Fußteile jeweils an den stirnseitigen Enden des Trägerprofils axial einschiebbar sind. Im Hohlraum des Trägerprofils sind eine Vorschaltdrossel, ein Starterelement sowie Stromzuführungsleitungen untergebracht. Insbesondere ist das Set für Leuchtstofflampen vorgesehen, deren Entladungsgefäß einen gegenüber Standardlampen kleineren Durchmesser von 26 mm aufweist.The invention relates to a fluorescent lamp set, consisting of a rod-shaped fluorescent lamp and an elongated, channel-shaped support profile, the width of which is only slightly larger than the diameter of the discharge vessel. The fluorescent lamp is arranged parallel to the carrier profile and without contact with it and is held in contact with holder parts, these being axially insertable at the front ends of the carrier profile by means of foot parts arranged on them. A series choke, a starter element and power supply lines are housed in the cavity of the carrier profile. In particular, the set is intended for fluorescent lamps, the discharge vessel of which has a diameter of 26 mm smaller than that of standard lamps.

Es sind Trägerprofile für Standard-Leuchtstofflampen (diese haben einen Rohrdruchmesser von 38 mm) bekannt, die z.B. rinnenförmig oder allseitig geschlossen quaderförmig ausgebildet sind, wobei im hohlförmigen Innern die Vorschaltdrossel untergebracht ist. Als Material für die Trägerprofile ist üblicherweise Metallblech verwendet, das gegenüber den an der Drossel auftretenden hohen Temperaturen beständig ist und das auch die Wärmeableitung übernimmt. Die Anordnung ist dabei so getroffen, daß das Trägerprofil zur Lampenseite hin geschlossen ist; z.B. ist bei einem U-förmigen Trägerprofil das mittlere Wandungsteil dem Lampenkörper zugewandt. Zwischen Trägerprofil und Lampenkörper ist stets ein Abstand von 1 bis 2 cm (oder mehr) eingehalten. Die an den Stirnseiten des Trägerprofils befindlichen Fassungen sind überwiegend fest montiert, sie bleiben bei einem Lampenwechsel in ihrer Position unverändert. Die Fassungen sind z.B. seitlich mit Schlitzen versehen, über die die Sockelstifte der Leuchtstofflampe eingeführt sind (der Lampenkörper wird beim Einsetzen achsparallel verschoben). Durch Drehung des Lampenkörpers um seine Längsachse ist eine Arretierung der Lampe erreicht. Die Lampen werden jeweils über einen Glimmzünder gezündet, der - evtl. in Kombination mit weiteren Schaltungselementen - in einem Startergehäuse aus Kunststoff untergebracht ist. Das Trägerprofil weist eine Aufnahme auf, in die der Starter austauschbar eingesetzt ist. Um das Auswechseln des Starters zu ermöglichen, ist dieser nur teilweise im Trägerprofil eingelassen - mit einem Teil ragt das Startergehäuse aus dem Trägerprofil heraus. Der Lampenkörper ist in einem gewissen Abstand dazu darüberliegend angeordnet. Die vorbeschriebenen Leuchtenausführungen können noch mit einer die Lampe abdeckenden Blende versehen sein.Carrier profiles for standard fluorescent lamps (these have a tube diameter of 38 mm) are known, which e.g. are formed channel-shaped or cuboid closed on all sides, the ballast being accommodated in the hollow interior. Metal sheet is usually used as the material for the support profiles, which is resistant to the high temperatures occurring at the throttle and which also takes over the heat dissipation. The arrangement is such that the carrier profile is closed towards the lamp side; e.g. the middle wall part faces the lamp body in the case of a U-shaped support profile. A distance of 1 to 2 cm (or more) is always maintained between the support profile and the lamp body. The lampholders on the end faces of the support profile are predominantly permanently installed; their position remains unchanged when the lamp is changed. The versions are e.g. Provided on the side with slots through which the base pins of the fluorescent lamp are inserted (the lamp body is moved parallel to the axis when inserted). The lamp is locked by rotating the lamp body about its longitudinal axis. The lamps are each ignited via a glow starter, which - possibly in combination with other circuit elements - is housed in a plastic starter housing. The carrier profile has a receptacle in which the starter is interchangeably inserted. To enable the starter to be replaced, it is only partially embedded in the carrier profile - the starter housing protrudes from the carrier profile with one part. The lamp body is arranged at a certain distance above it. The luminaire versions described above can also be provided with an aperture covering the lamp.

Nach der DE-B-1 097 032 ist ein Träger für eine oder mehrere Leuchtstofflampen bekannt, der ein langgestrecktes, schmales, rinnenförmiges Profil aufweist, und an dessen Stirnseiten jeweils Halter mit den Lampenfassungen angebracht sind. Zum Zwecke der Verpackung und des Transports sind die Fassungshalter vom Träger lösbar. Hierzu sind an den Fassungshaltern befestigte U-förmige Federbügel vorgesehen, die in den Träger seitlich einschiebbar sind. Einer der Schenkel eines jeden Federbügels weist ein abgebogenes Ende auf, das in einen entsprechenden Querschlitz der nach innen abgewinkelten Trägerlängsränder einzurasten ist. Bei den vorliegenden üblichen Drehfassungen mit seitlichem Schlitz sind die Lampen durch achsparallele Verschiebung und anschließendes Drehen einsetzbar, dabei bleiben die Fassungshalter mit dem Träger in eingeschobener Stellung der Federbügel fest verbunden. Die Fassungen sind derart am Träger angeordnet, daß die offene Seite des rinnenförmigen Trägers (bei montierter Leuchte zur Wand hin gerichtet) von den eingesetzten Lampen abgewandt ist. Die Lampen haben zum Träger den üblichen großen Abstand von mehr als 1 cm, wobei die Breite des Trägers nur wenig größer als der Durchmesser eines Lampenkolbens ist. Im Hohlraum des rinnenförmigen Trägers sind Vorschaltdrossel und Starter untergebracht, die über die abgewinkelten Randteile des Trägers fixiert sind.According to DE-B-1 097 032, a carrier for one or more fluorescent lamps is known, which has an elongated, narrow, channel-shaped profile and on the end faces of which holders with the lamp holders are attached. The holder can be detached from the carrier for packaging and transport. For this purpose, U-shaped spring clips are provided on the holder, which can be inserted laterally into the carrier. One of the legs of each spring clip has a bent end, which is to be snapped into a corresponding transverse slot in the longitudinally angled carrier edges. In the current rotary sockets with a slot on the side, the lamps can be used by moving them parallel to the axis and then rotating them, while the socket holders remain firmly connected to the carrier in the inserted position of the spring clips. The sockets are arranged on the carrier in such a way that the open side of the channel-shaped carrier (facing the wall when the lamp is installed) faces away from the lamps used. The lamps have the usual large distance of more than 1 cm from the carrier, the width of the carrier being only slightly larger than the diameter of a lamp bulb. Ballast choke and starter are accommodated in the cavity of the trough-shaped carrier, which are fixed via the angled edge parts of the carrier.

Die bekannten Anordnungen sind insbesondere in ihrer Dimensionierung von Nachteil. Die Trägerprofile sind meist verhältnismäßig hoch - nicht zuletzt durch die Abmessungen der Vorschaltgeräte bedingt - und, da auch ein beträchtlicher Abstand zwischen Trägerprofil und Lampenkörper vorhanden ist, wird relativ viel Raum bei der Installation benötigt.The known arrangements are particularly disadvantageous in terms of their dimensions. The carrier profiles are usually relatively high - not least due to the dimensions of the ballasts - and, since there is also a considerable distance between the carrier profile and the lamp body, a relatively large amount of space is required for the installation.

Der Erfindung liegt die Aufgabe zugrunde, ein Leuchtstofflampen-Set in kompakter Bauweise zu schaffen. Es soll einfach in der Handhabung sein und vielfältige Einsatzmöglichkeiten bieten.The invention has for its object to provide a fluorescent lamp set in a compact design. It should be easy to use and offer a wide range of uses.

Das Leuchtstofflampen-Set mit den im Oberbegriff des Hauptanspruchs genannten Merkmalen ist erfindungsgemäß dadurch gekennzeichnet, daß die offene Seite des Trägerprofils dem Entladungsgefäß der Leuchtstofflampe zugewandt ist und die Seitenwände des Trägerprofils so weit hochgezogen sind, daß das Entladungsgefäß geringfügig im Trägerprofil eingebettet ist, wobei der unterhalb des Entladungsgefäßes befindliche Hohlraum des Trägerprofils - begrenzt durch das Bodenteil - eine Höhe h aufweist, die kleiner ist als der Durchmesser d des Entladungsgefäßes, und daß die Fassungsteile an den stirnseitigen Enden des Trägerprofils aus ihrer normalen Betriebsstellung axial so weit nach außen in eine gerastete Stellung verschiebbar ausgebildet sind, daß die Leuchtstofflampe ohne weitere Maßnahmen aus den Fassungsteilen herausnehmbar ist.The fluorescent lamp set with the features mentioned in the preamble of the main claim is characterized in that the open side of the support profile faces the discharge vessel of the fluorescent lamp and the side walls of the support profile are raised so far that the discharge vessel is slightly embedded in the support profile, the below the discharge vessel cavity of the support profile - limited by the bottom part - has a height h which is smaller than the diameter d of the discharge vessel, and that the socket parts at the front ends of the support profile from their normal operating position axially outwards into a locked position Position are designed so that the fluorescent lamp without further measures is removable from the socket parts.

Indem z.B. eine Leuchtstofflampe verwendet ist, deren Entladungsgefäß einen Durchmesser d von nur 26 mm hat, ist eine äußerst kompakte Leuchteneinheit geschaffen. Die lichte Höhe h zwischen dem Bodenteil des Trägerprofils und der Unterseite des Entladungsgefäßes beträgt vorzugsweise etwa 2/3 des Durchmessers d des Entladungsgefäßes.By e.g. a fluorescent lamp is used, the discharge vessel of which has a diameter d of only 26 mm, an extremely compact luminaire unit is created. The clear height h between the base part of the support profile and the underside of the discharge vessel is preferably approximately 2/3 of the diameter d of the discharge vessel.

Das im Innern des Trägerprofils untergebrachte Vorschaltgerät ist eine Drossel von extrem flacher Bauweise. Ihre maximale Höhe - mit evtl. umgebender Isolierung - ist durch die Höhe h des Trägerprofils festgelegt. Das rohrförmige Entladungsgefäß ist geringfügig im Trägerprofil eingebettet, wodurch eine der Lampe zugewandte Abdeckung beim Trägerprofil entfallen kann; die Lampe ist jedoch mit dem Trägerprofil nicht in Berührung. In dieser Anordnung stellen Trägerprofil und Lampe eine bauliche Einheit mit minimalen Querschnittsabmessungen dar.The ballast housed inside the carrier profile is a choke with an extremely flat design. Their maximum height - with any surrounding insulation - is determined by the height h of the support profile. The tubular discharge vessel is slightly embedded in the carrier profile, so that a cover facing the lamp can be omitted in the carrier profile; however, the lamp is not in contact with the support profile. In this arrangement, the support profile and lamp represent a structural unit with minimal cross-sectional dimensions.

Um die Minimalabmessungen erreichen zu können, sind auch die Fassungen entsprechend ausgebildet. So sind die Fassungsteile axial verschiebbar. Sie bestehen jeweils aus einer den Lampensockel aufnehmenden Kappe und einem daran angesetzten flacheren Fußteil in Form eines langgestreckten Quaders, das bei montierter Lampe im Trägerprofil eingeschoben ist. Zum Lampenwechsel werden die Fassungsteile vom Trägerprofil seitlich abgezogen; sie bleiben allerdings mit dem Trägerprofil über die Enden der Fußteile verbunden. Die Fixierung des Fassungsteile in den beiden Stellungen ist durch eine Rastvorrichtung vorgenommen. Im eingeschobenen Zustand der Fassungsteile sind die Lampensockel von den jeweiligen Fassungskappen vollständig umschlossen. Die Fassungsteile weisen in einem hinteren Raum der Kappe, der in den hohlförmig ausgebildeten Fußteil übergeht, Steckanschlüsse für die Kontaktierung der Lampensockelstifte auf. Der Anschluß der Lampe erfolgt durch einfaches Einstecken der Sockelstifte in am Kappenteil vorhandene Bohrungen, hinter denen die Stromanschlüsse angebracht sind. Ein Verdrehen des Lampenkörpers - wie dies bei den meisten herkömmlichen Leuchtstofflampenarmaturen zu erfolgen hat - ist bei der erfindungsgemäßen Ausführung des Trägerprofils nicht notwendig. Die bei eingesetzter Lampe auf die Sockel aufgeschobenen Fassungsteile ergeben eine sichere Halterung.In order to achieve the minimum dimensions, the sockets are also designed accordingly. So the frame parts are axially displaceable. They each consist of a cap receiving the lamp base and a flatter foot part attached to it in the form of an elongated cuboid, which is pushed into the carrier profile when the lamp is mounted. To change the lamp, the socket parts are pulled off the side of the support profile; however, they remain connected to the support profile via the ends of the foot parts. The frame parts are fixed in the two positions by a locking device. When the socket parts are pushed in, the lamp bases are completely enclosed by the respective socket caps. The socket parts have plug connections for contacting the lamp base pins in a rear space of the cap, which merges into the hollow base part. The lamp is connected by simply inserting the socket pins into the holes on the cap part, behind which the power connections are attached. Twisting the lamp body - as is the case with most conventional fluorescent lamp fittings - is not necessary in the embodiment of the support profile according to the invention. The socket parts pushed onto the base when the lamp is inserted result in a secure mounting.

Indem die Fassungsteile aber auch vom Trägerprofil vollständig abziehbar sind - die Rastvorrichtung ist entsprechend ausgebildet - lassen sich gleichartige Fassungsteile für verschieden lange Trägerprofile verwenden. Es können somit Leuchtstofflampen-Sets nach einer Art Baukastensystem für verschiedene Leistungsstufen von Leuchtstofflampen (mit einem Durchmesser von 26 mm) geschaffen werden. Lediglich die Trägerprofile mit den integrierten Vorschaltgeräten und Starterelementen müssen auf den jeweiligen Lampentyp abgestimmt sein.However, since the frame parts can also be completely removed from the support profile - the latching device is designed accordingly - identical frame parts can be used for support profiles of different lengths. Fluorescent lamp sets can thus be created according to a kind of modular system for different power levels of fluorescent lamps (with a diameter of 26 mm). Only the support profiles with the integrated ballasts and starter elements have to be matched to the respective lamp type.

Das erfindungsgemäße Leuchtstofflampen-Set kann als anschlußfertige Einheit ausgebildet sein, es weist dann ein aus einem Fassungsteil herausführendes Kabel mit Netzstecker auf. Somit ist das Lampen-Set bezüglich des Einsatzortes variabel (Möbelbeleuchtung etc.). Das Lampen-Set kann aber auch für einen Festanschluß sein, z.B. bei Kabelauslaß an einer Zimmerwand. Der Anschluß wird dann an einer Klemme im Trägerprofil vorgenommen, wobei das Bodenteil des Trägers eine Einführungsöffnung für das Netzkabel aufweist.The fluorescent lamp set according to the invention can be designed as a ready-to-connect unit; The lamp set is therefore variable with regard to the place of use (furniture lighting etc.). The lamp set can also be for a permanent connection, e.g. with cable outlet on a room wall. The connection is then made to a clamp in the carrier profile, the bottom part of the carrier having an insertion opening for the mains cable.

Das erfindungsgemäße Leuchtstofflampen-Set stellt eine kompakte Leuchteneinheit dar mit minimalen Querschnittsabmessungen. Aufgrund des geringen Platzdarfes bei der Installation bieten sich vielfältige Einsatzmöglichkeiten. Die Handhabung des Sets ist, insbesondere was den Lampenwechsel anbelangt, äußerst einfach und sicher.The fluorescent lamp set according to the invention represents a compact lamp unit with minimal cross-sectional dimensions. Due to the small space required for installation, there are many possible uses. The handling of the set is extremely simple and safe, especially when it comes to changing the lamp.

Aus der Darstellung in Figur 1 wird insbesondere die kompakte Bauweise des Leuchtstofflampen-Sets 1 deutlich. Diese besteht aus der Leuchtstofflampe 2 - im Ausführungsbeispiel ist eine 18-Watt-Lampe verwendet - und dem Trägerprofil 3 mit an den stirnseitigen Enden angebrachten Fassungsteilen 4, 5. Im Innern des Trägerprofils 3 ist eine flache Vorschaltdrossel 6 untergebracht. Letztere ist mit einer Temperatursicherung 7 - an der einen Stirnseite - versehen und ist vorteilhaft mit dem Starterelement 8 - an der anderen Stirnseite - baulich vereinigt.The illustration in FIG. 1 shows in particular the compact design of the fluorescent lamp set 1. This consists of the fluorescent lamp 2 - in the exemplary embodiment an 18-watt lamp is used - and the carrier profile 3 with mounting parts 4, 5 attached to the front ends. A flat ballast choke 6 is accommodated in the interior of the carrier profile 3. The latter is provided with a temperature fuse 7 - on one end face - and is advantageously structurally combined with the starter element 8 - on the other end face.

Wie auch die Figuren 2 und 3 zeigen, ist das rohrförmige Entladungsgefäß 9 der Leuchtstofflampe 2 - dieses hat einen Durchmesser d von 26 mm - im rinnenförmigen Trägerprofil 3 (in etwa C-förmig) geringfügig eingebettet, indem die Seitenwände 10 das Trägerprofils 3 - dieses besteht aus Metallblech - entsprechend hochgezogen sind. Der unterhalb des Entladungsgefäßes 9 befindliche Hohlraum des Trägerprofils weist eine Höhe h auf - begrenzt durch das Bodenteil 11 - die kleiner ist als der Durchmesser d; die Höhe h beträgt vorzugsweise etwa 2/3 des Durchmessers d. Die Breite b des Trägerprofils ist nur wenig größer als der Durchmesser d des Entladungsgefäßes 9. Die im Trägerprofil 3 integrierte Vorschaltdrossel 6 weist entsprechend geringe Querschnittsabmessungen auf. Mit den am Entladungsgefäß 9 entlangführenden Randteilen 12 der Seitenwände 10, die dachförmig abgewinkelt sind, ist vorteilhaft das Vorschaltgerät 6 (schematisiert dargestellt) im Trägerprofil 3 fixiert. Das Vorschaltgerät 6 ist von einer Isolierung umgeben, die das dichte Anliegen der Wandungsteile 10, 11 möglich macht.As also shown in FIGS. 2 and 3, this is tubular discharge vessel 9 of the fluorescent lamp 2 - this has a diameter d of 26 mm - is slightly embedded in the trough-shaped carrier profile 3 (approximately C-shaped) by the side walls 10 of the carrier profile 3 - this consists of sheet metal - being raised accordingly. The cavity of the support profile located below the discharge vessel 9 has a height h - delimited by the base part 11 - which is smaller than the diameter d; the height h is preferably about 2/3 of the diameter d. The width b of the carrier profile is only slightly larger than the diameter d of the discharge vessel 9. The ballast choke 6 integrated in the carrier profile 3 has correspondingly small cross-sectional dimensions. The ballast 6 (shown schematically) is advantageously fixed in the carrier profile 3 with the edge parts 12 of the side walls 10 which run along the discharge vessel 9 and which are angled like a roof. The ballast 6 is surrounded by insulation, which makes the tight contact of the wall parts 10, 11 possible.

In der Figur 2 ist auch die axiale Verschiebbarkeit der Fassungsteile 4, 5 gezeigt. Das Fassungsteil 4 ist aus dem Trägerprofil ein Stück herausgezogen, wodurch der Lampensockel 13 freigelegt ist. Der sich am gegenüberliegenden Ende befindliche Lampensockel ist von dem Fassungsteil 5, das im Trägerprofil e!nge- schoben ist, vollständig umschlossen; das Sockelteil ist dadurch berührungssicher untergebracht. Um einen Lampenwechsel vorzunehmen, werden die Fassungsteile 4, 5 (evtl. auch nur eines der Fassungsteile) vom Trägerprofil 3 abgezogen; die Fassungsteile bleiben jedoch mit dem Trägerprofil verbunden.FIG. 2 also shows the axial displaceability of the mounting parts 4, 5. The socket part 4 is pulled out of the carrier profile a bit, whereby the lamp base 13 is exposed. The lamp base located at the opposite end is completely enclosed by the holder part 5, which is pushed into the support profile e; the base part is housed safe from touch. In order to change the lamp, the socket parts 4, 5 (possibly only one of the socket parts) are removed from the carrier profile 3; however, the frame parts remain connected to the support profile.

Die Fassungsteile 4, 5 sind aus Kunststoff und bestehen jeweils aus einer das Lampenende aufnehmenden Kappe 14 und einem daran angesetzten flacheren Fußteil 15 (siehe auch Figur 8); letzteres ist in das Trägerprofil 3 einschiebbar. Wie insbesondere der Figur 4 zu entnehmen ist, sind die Fassungsteile 4, 5 jeweils aus zwei Schalenhälften 16, 17 gebildet, die über eine Schnappverbindung zusammengefügt sind. Auf den jeweiligen Fußteilen 15 liegt eine Rastfeder 18 auf, die aus einem Blechstanzteil besteht (insbesondere Figuren 4, 5 und 6). Die Rastfeder 18 hat ein ebenes Mittelteil 19, an dem die Laschenpaare 20, 21 angebracht sind. Diese Laschen 20, 21 sind gegenüber dem ebenen Mittelteil 19 bogenförmig vorgespannt (Figur 6). Mittels der Klammerteile 22 ist die Rastfeder 18 am Fußteil 15 festgeklemmt. Bei eingeschobenem Fassungsteil 4, 5 liegen die bogenförmigen Laschen 20, 21 in den dachförmig abgewinkelten Randteilen 12 des Trägerprofils 3. Die Ausgestaltung der Laschen 20, 21 und entsprechende Anschläge an den jeweiligen Enden des Trägerprofils 3 ergeben zwei Raststufen für die Fassungsteile 4, 5. Die Anschläge sind durch Verschränkungen 23 an den Enden der Randteile 12 gebildet (insbesondere Figuren 4 und 7). Während die Laschen 20 zum Herausziehen der Fassungsteile 4, 5 nach Überwindung eines gewissen anfänglichen Widerstandes über die Verschränkungen 23 hinweggleiten können, ist für die Laschen 21 durch die Verschränkungen 23 eine - ohne Werkzeug - unüberwindliche Sperre vorgegeben, die bewirkt, daß die vom Trägerprofil 3 seitlich abgezogenen Fassungsteile 4, 5 am Trägerprofil 3 befestigt bleiben. Dies dient insbesondere der mechanischen Sicherung der Kabelanschlüsse in den Fassungsteilen 4, 5 und schließt ein Berühren elektrischer Kontakte beim Lampenwechsel aus. Der eingeschobene Zustand der Fassungsteile 4, 5 wird durch das Zusammenwirken der Laschen 20 mit den Verschränkungen 23 gesichert. Jeweils unterhalb der Laschen 20, 21 weist das Fußteil 15 Ausnehmungen 24 auf (Figur 2), die den für die Federung der Laschen 20, 21 notwendigen Raum abgeben.The socket parts 4, 5 are made of plastic and each consist of a cap 14 receiving the lamp end and a flatter foot part 15 attached thereto (see also FIG. 8); the latter can be inserted into the carrier profile 3. As can be seen in particular from FIG. 4, the mounting parts 4, 5 are each formed from two shell halves 16, 17, which are joined together via a snap connection. On the respective foot parts 15 there is a detent spring 18 which consists of a stamped sheet metal part (in particular FIGS. 4, 5 and 6). The detent spring 18 has a flat central part 19 on which the pairs of tabs 20, 21 are attached. These tabs 20, 21 are preloaded in an arc shape relative to the flat central part 19 (FIG. 6). The latching spring 18 is clamped to the foot part 15 by means of the clamp parts 22. When the frame part 4, 5 is pushed in, the arc-shaped tabs 20, 21 lie in the roof-shaped angled edge parts 12 of the support profile 3. The design of the tabs 20, 21 and corresponding stops at the respective ends of the support profile 3 result in two locking stages for the frame parts 4, 5. The stops are formed by interlocks 23 at the ends of the edge parts 12 (in particular FIGS. 4 and 7). While the tabs 20 for pulling out the frame parts 4, 5 can slide over the entanglements 23 after overcoming a certain initial resistance, the tabs 21 are given an insurmountable lock without tools, which causes that of the carrier profile 3 laterally removed frame parts 4, 5 remain attached to the carrier profile 3. This serves in particular to mechanically secure the cable connections in the socket parts 4, 5 and precludes touching electrical contacts when changing the lamp. The inserted state of the frame parts 4, 5 is secured by the interaction of the tabs 20 with the interlocks 23. In each case below the tabs 20, 21, the foot part 15 has recesses 24 (FIG. 2) which provide the space required for the suspension of the tabs 20, 21.

In Figur 8 ist der Innenaufbau des Fassungsteiles 4 wiedergegeben (das Fassungsteil 5 ist - was die Kontaktierungsteile betrifft - analog aufgebaut). Die Kappe 14 weist eine Zwischenwand 25 auf, wodurch ein hinterer Kappenteil 26 gebildet ist; in diesem ist - bei eingesetzter Lampe - die Kontaktierung der Sockelstifte vorgenommen. Der hintere Kappenteil 26 und das hohlförmig ausgebildete Fußteil 15 bilden einen zusammenhängenden Raum. Die Zwischenwand 25 ist mit Bohrungen 27 versehen, durch die die Lampensockelstifte hindurchgeführt werden. Hinter den Bohrungen 27 sind Kontaktbleche 28 eingesetzt, mittels derer die Kontaktierung der Sockelstifte erfolgt (nicht dargestellt). Den Aufbau eines Kontaktbleches geben die Figuren 9 und 10 wieder. Die Kontaktbleche 28 bestehen jeweils aus einem Kontaktteil 29 und den Klemmfahnen 30. Während in Figur 9 das Stanzstück gezeigt ist, ist in Figur 10 das geformte Kontaktblech 28 dargestellt. Das im wesentlichen ebene Kontaktteil 29 weist - etwa mittig angeordnet - eine leichte Verwindung 31 auf, an der der Sockelstift jeweils vorbeigeführt ist und mit einer gewissen Federkraft kontaktiert wird. Die Kontaktbleche 28 sind jeweils gegenüber den Achsen der Bohrungen 27 geringfügig versetzt angebracht, wobei die im wesentlichen ebenen Kontaktteile 29 parallel zu den eingeführten Sockelstiften verlaufen. Die Kontaktbleche 28 sind in Führungen 32 des hinteren Kappenteiles 26 eingeschoben. Mittels der Klemmfahnen 30 sind die Stromzuführungslitzen 33 festgeklemmt.FIG. 8 shows the internal structure of the socket part 4 (the socket part 5 is constructed analogously - as far as the contacting parts are concerned). The cap 14 has an intermediate wall 25, whereby a rear cap part 26 is formed; in this - when the lamp is inserted - the socket pins are contacted. The rear cap part 26 and the hollow-shaped foot part 15 form a coherent space. The intermediate wall 25 is provided with bores 27 through which the lamp base pins are passed. Contact plates 28 are inserted behind the bores 27, by means of which the base pins are contacted (not shown). Figures 9 and 10 show the structure of a contact plate. The contact plates 28 each consist of a contact part 29 and the clamping lugs 30. While the stamped piece is shown in FIG. 9, the shaped contact plate 28 is shown in FIG. The essentially planar contact part 29 has a slight twist 31, arranged approximately in the middle, to which the base pin is guided in each case and is contacted with a certain spring force. The contact plates 28 are each offset slightly from the axes of the bores 27, the essentially planar contact parts 29 running parallel to the inserted base pins. The contact plates 28 are inserted into guides 32 of the rear cap part 26. The power supply strands 33 are clamped by means of the clamping tabs 30.

Die im hohlförmigen Trägerprofil 3 verlaufenden Stromleitungskabel sind über die hohlen Fußteile 15 in die hinteren Kappenteile 26 der Fassungsteile 4, 5 geführt. Am Fassungsteil 5 ist das Netzkabel 34 eingeführt - vorteilhaft axial bezüglich des Trägerprofils 3. Das Fassungsteil 4 weist dagegen einen Ein/Aus-Schalter 35 auf (insbesondere Figuren 2 und 8), der ebenfalls bezüglich des Trägerprofils 3 axial andeordnet ist.The power line cables running in the hollow support section 3 are guided via the hollow base parts 15 into the rear cap parts 26 of the socket parts 4, 5. The mains cable 34 is inserted at the socket part 5 - advantageously axially with respect to the carrier profile 3. The socket part 4, on the other hand, has an on / off switch 35 (in particular FIGS. 2 and 8), which is likewise with respect to the carrier Profiles 3 is arranged axially on d .

Um das Lampen-Set nicht nur wie üblich über das Bodenteil des Trägerprofils an einer Befestigungsfläche anzubringen, weisen die Fußteile 15 - sowie die Klammerteile 22 - der Fassungen 4, 5 parallel zum Bodenteil 11 verlaufende Durchführungen 35 auf; diese dienen zur Aufnahme von Befestigungsschrauben oder dergleichen (Figuren 2 und 8). Somit läßt sich das Lampen-Set auch mit einer der Seitenflächen 10 des Trägerprofils 3 an der Befestigungsfläche anliegend montieren. Das Bodenteil 11 des Trägerprofils 3 ist zusätzlich mit den üblichen Befestigungsmitteln für eine Wandmontage versehen.In order not only to attach the lamp set to a fastening surface as usual via the base part of the support profile, the base parts 15 - and the clamp parts 22 - of the sockets 4, 5 have bushings 35 running parallel to the base part 11; these serve to hold fastening screws or the like (FIGS. 2 and 8). Thus, the lamp set can also be fitted with one of the side surfaces 10 of the carrier profile 3 against the fastening surface. The bottom part 11 of the carrier profile 3 is additionally provided with the usual fastening means for wall mounting.
