Description

Die vorliegende Erfindung bezieht sich auf eine Beleuchtungsvorrichtung mit Stromschienen zum Betrieb auf niedrigen Spannungen. Stromschienen-Beleuchtungsvorrichtungen sind an sich bekannt. Werden solche Vorrichtungen auf den üblichen Netzspannungen von 220 V oder 110 V betrieben, so sind für deren Installation und Betrieb alle Vorschriften und Vorsichtsmassnahmen für den Umgang mit gefährlichen Spannungen einzuhalten und zu befolgen. Daraus ergeben sich in der Regel starre Stromschienen mit verdeckter und geschützter Führung der Stromleiter und besondere Formgebung der Schienen und der mit den Beleuchtungskörpern verbundenen Stromabnehmer.The present invention relates to a lighting device with busbars for operation at low voltages. Track lighting devices are known per se. If such devices are operated at the usual mains voltages of 220 V or 110 V, all regulations and precautionary measures for handling dangerous voltages must be observed and followed for their installation and operation. As a rule, this results in rigid conductor rails with concealed and protected guidance of the conductor and special shape of the rails and the pantographs connected to the lighting fixtures.

Die Installation ist in der Regel einem zugelassenen Installateur überlassen und so vorzunehmen, dass allen Sicherheitsaspekten Rechnung getragen wird. Dies alles ist auch mit erheblichen Kosten verbunden. Mit der vorzusehenden verdeckten Führung der Stromleiter ist nahezu zwangsläufig eine U- oder C-Form des Stromschienen-Querschnittes verbunden. Daraus ergibt sich ebenso zwingend, dass die die Stromabnehmer tragenden Lampensockel in die Stromschienen eingeschoben werden müssen.The installation is usually left to an approved installer and must be carried out in such a way that all safety aspects are taken into account. All of this is also associated with considerable costs. A U- or C-shape of the conductor rail cross-section is almost inevitably connected to the concealed guidance of the conductor. This also means that the lamp bases carrying the pantographs must be inserted into the busbars.

Anderseits sind Niederspannungsbeleuchtungsvorrichtungen (für Spannungen im Bereich von etwa 6 bis 24 Volt) bekannt, deren Stromschiene aus frei den zu beleuchtenden Raum durchquerenden Drahtpaaren bestehen. Diese Lösung ist kostengünstig und kann raumgestalterisch als reizvoll empfunden werden; anderseits wirkt sie stilverpflichtend und engt die Vielfalt von beleuchtungstechnischen und gestalterischen Möglichkeiten stark ein.On the other hand, low-voltage lighting devices (for voltages in the range of about 6 to 24 volts) are known whose busbars consist of wire pairs freely crossing the space to be illuminated. This solution is inexpensive and can be perceived as attractive in terms of interior design; on the other hand, it has a style-binding effect and severely narrows the variety of lighting and design options.

Aus der DE-B-1 282 126 ist eine Vorrichtung mit zwei parallelen ferromagnetischen Stromleitern bekannt, auf welchen eine Leuchte mittels elektrisch leitenden Dauermagneten haftet, wobei gleichzeitig dafür gesorgt ist, dass der die Dauermagnete enthaltende Sockel der Leuchte nicht so auf die Stromleiter aufgesetzt werden kann, dass ein Kurzschluss entsteht. Der Nachteil dieser bekannten Lösung besteht aus der Sicht des Anwenders im verhältnismässig massiven Aufbau der Stromschiene, mit Grundaufbau und Stromleitern, die sich in viele Räume nicht ohne weiteres integrieren lässt, die eine Lagerhaltung verschiedener Längen notwendig macht und damit das Produkt verteuert.From DE-B-1 282 126 a device with two parallel ferromagnetic current conductors is known, on which a lamp adheres by means of electrically conductive permanent magnets, whereby at the same time it is ensured that the base of the lamp containing the permanent magnets is not so placed on the current conductors can cause a short circuit. The disadvantage of this known solution from the point of view of the user is the relatively solid structure of the busbar, with basic structure and current conductors, which cannot be easily integrated into many rooms, which makes storage of different lengths necessary and thus makes the product more expensive.

Die Aufgabe, die an die vorliegende Erfindung gestellt ist, ist die Schaffung einer durch den Oberbegriff abgegrenzten Beleuchtungsvorrichtung, die zur Selbstmontage geeignet und kostengünstig herzustellen ist und zudem raumgestalterischen sowie beleuchtungstechnischen Anforderungen im weitesten Masse gerecht zu werden vermag.The object of the present invention is to create a lighting device which is delimited by the preamble and which is suitable for self-assembly and can be produced inexpensively and, moreover, can meet the interior design and lighting requirements to the greatest possible extent.

Die Lösung der gestellten Aufgabe ist im Patentanspruch 1 gegeben.The solution to the problem is given in claim 1.

Der Erfindungsgedanke wird mithilfe der beiliegenden Zeichnungen erläutert und in einigen Ausführungsbeispielen dargestellt.The idea of the invention is explained with the aid of the accompanying drawings and illustrated in some exemplary embodiments.

Fig. 1 zeigt ein Ausführungsbeispiel der erfindungsgemässen Vorrichtung in mehr prinzipieller Weise. Eine Stromschiene 1, bestehend aus einem isolierenden Träger 2 und zwei Leiterbahnen 3, trägt einen Lampenfuss 4 mit einem abgebrochen dargestellten Stiel 5 für den Beleuchtungskörper. An der Sohle des Trägers 2 ist eine Haftfolie 6 angebracht, mithilfe derer die Stromschiene 1 entweder direkt an Gebäudeteilen, wie Decken, Wänden, Balken, oder aber an besonderen Tragschienen angebracht werden kann.1 shows an embodiment of the device according to the invention in a more basic manner. A busbar 1, consisting of an insulating support 2 and two conductor tracks 3, carries a lamp base 4 with a stem 5 shown broken off for the lighting fixture. An adhesive film 6 is attached to the sole of the carrier 2, by means of which the busbar 1 can either be attached directly to parts of the building, such as ceilings, walls, beams, or else on special mounting rails.

Die Fig. 2 bis 8 zeigen besondere Ausführungsbeispiele der Stromschiene 1 jeweils im Querschnitt. Jenes gemäss Fig. 2 zeigt einen Träger 2, beispielsweise aus einem Elastomer gefertigt. Der Querschnitt dieses Trägers 2 weist vier Nuten 7 auf, in welche zwei Stahlbänder 8 eingelegt werden können. In der Mitte bezüglich seiner Längsachse weist der Träger 2 gemäss Fig. 2 eine beispielsweise rechteckige Erhebung 9 auf.2 to 8 show special embodiments of the busbar 1 in cross section. 2 shows a carrier 2, for example made of an elastomer. The cross section of this support 2 has four grooves 7, in which two steel strips 8 can be inserted. In the middle with respect to its longitudinal axis, the carrier 2 according to FIG. 2 has, for example, a rectangular elevation 9.

Die Stahlbänder 8 sind mindestens auf ihrer Oberseite blank. Sie dienen einerseits der Stromleitung, anderseits als Anker für einen oder mehrere Dauermagnete 21,24 gemäss den Fig. 9,10,11. Die Sohle des Trägers 2 ist mit der Haftfolie 6 versehen. Die Erhebung 9 verhindert, dass Metallteile, z.B. die Haftmagnete 21,24, quer über die beiden Stahlbänder 8 gelegt werden können und damit einen Kurzschluss verursachen. Ferner dient sie zur Führung, bzw. genauen Positionierung des Lampenfusses 4.The steel strips 8 are bare at least on their upper side. They serve on the one hand to conduct electricity, and on the other hand as an anchor for one or more permanent magnets 21, 24 according to FIGS. 9, 10, 11. The sole of the carrier 2 is provided with the adhesive film 6. The elevation 9 prevents metal parts, e.g. the holding magnets 21, 24 can be placed across the two steel strips 8 and thus cause a short circuit. Furthermore, it serves to guide or precisely position the lamp base 4.

Im Ausführungsbeispiel gemäss Fig. 3 sind die Stahlbänder 8 auf den Träger 2 aufgeklebt. Damit entfallen die Nuten 7. Hingegen weist der Träger 2 auf jeder Seite einen Randschutz 12 auf.In the exemplary embodiment according to FIG. 3, the steel strips 8 are glued to the carrier 2. This eliminates the grooves 7. In contrast, the carrier 2 has an edge protection 12 on each side.

Fig. 4 zeigt eine Variante zum Ausführungsbeispiel gemäss Fig. 3. Die Stahlbänder 8 erstrecken sich bis an den Rand des Trägers 2. Dieses Ausführungsbeispiel liegt auch der mehr prinzipiellen Darstellung von Fig. 1 zugrunde.FIG. 4 shows a variant of the exemplary embodiment according to FIG. 3. The steel strips 8 extend to the edge of the carrier 2. This exemplary embodiment is also based on the more basic illustration of FIG. 1.

In Fig. 5 ist ein Ausführungsbeispiel dargestellt, bei dem der Träger 2 entfällt, und nur die Erhebung 9 aus einem beispielsweise elastomeren Kunststoff vorhanden ist. Die beiden Stahlbänder 8 und der die Erhebung 9 bildende Kunststoffstreifen sind direkt auf die Haftfolie 6 geklebt. Damit ergibt sich eine besonders flache Ausführung.5 shows an embodiment in which the carrier 2 is omitted and only the elevation 9 is made of, for example, an elastomeric plastic. The two steel strips 8 and the elevation 9 plastic strips are glued directly onto the adhesive film 6. This results in a particularly flat design.

Das Ausführungsbeispiel gemäss Fig. 6 weist einen Träger 2 mit einer Vertiefung 13 auf (anstelle der Erhebung 9). Der entsprechende Lampenfuss 4 ist in Fig. 12 dargestellt und gesondert beschrieben. Eine zeichnungsmässig nicht erfasste Variante zu den Ausführungsbeispielen gemäss Fig. 2 bis 6 besteht in der Verwendung eines flachen, feindrahtigen Stahlgeflechtes anstatt eines Stahlbandes 8. Anstelle einer Klebeverbindung mit dem Träger 2 wird dieses Stahlgeflecht beispielsweise zusammen mit dem bandförmigen Träger 2 extrudiert.6 has a carrier 2 with a recess 13 (instead of the elevation 9). The corresponding lamp base 4 is shown in FIG. 12 and described separately. A variant of the exemplary embodiments according to FIGS. 2 to 6, which is not recorded in the drawing, consists in using a flat, fine-wire steel mesh instead of a steel strip 8. Instead of an adhesive connection with the carrier 2, this steel mesh is extruded, for example, together with the band-shaped carrier 2.

Die Stahlbänder 8 sind gemäss Fig. 9 auf ihrer Oberflächen über die Breite eines Bereiches 18 isolierend beschichtet, über den Rest ihrer Breite blank oder galvanisch veredelt, beispielsweise vernickelt. Als Träger für die Stahlbänder 8 dient ein isolierendes Kunststoffband 19, beispielsweise mit elastomeren Eigenschaften, das an seiner Sohle, wie alle vorhergehenden Ausführungungsbeispiele, mit einer Haftfolie 6 versehen ist.According to FIG. 9, the steel strips 8 are coated on their surfaces in an insulating manner over the width of a region 18, and are bare or electroplated, for example nickel-plated, over the rest of their width. An insulating plastic band 19, for example with elastomeric properties, is used as the carrier for the steel strips 8, which, like all previous exemplary embodiments, is provided with an adhesive film 6 on its sole.

Fig. 8 zeigt eine Variante zu Fig. 7. Hier ist das isolierende Kunststoffband 19 weggelassen; die Stahlbänder 8 sind direkt mit der Haftfolie 6 verklebt, im übrigen aber gleich ausgeführt, wie im vorangehenden Ausführungsbeispiel.Fig. 8 shows a variant of Fig. 7. Here, the insulating plastic tape 19 is omitted; the steel strips 8 are glued directly to the adhesive film 6, but otherwise have the same design as in the previous exemplary embodiment.

Die erfindungsgemässen Stromschienen gemäss Fig. 2 bis 7 sind alle so flach ausgeführt, dass sie im nicht montierten Zustande bequem aufgerollt werden können. Damit ist es dem Verbraucher möglich, die benötigte Länge von der Rolle abschneiden zu lassen und sie vermittels der Haftfolie 6 einfach am vorgesehenen Gebäudeteil anzubringen. Wegen der flachen Ausführung ist es ohne weiteres möglich, die erfindungsgemässe Stromschiene auch über Vorsprünge oder Balken herumzukleben. Dann werden die mit einem Transformator verbundene Stromzuführung und die vorgesehenen Lampen auf den erfindungsgemässen Lampenfüssen aufgesetzt und die gesamte Vorrichtung ist betriebsbereit.The busbars according to the invention according to FIGS. 2 to 7 are all designed so flat that they can be rolled up comfortably in the unmounted state. It is thus possible for the consumer to have the required length cut off the roll and to simply attach it to the intended part of the building by means of the adhesive film 6. Because of the flat design, it is easily possible to glue the busbar according to the invention also over projections or beams. Then the power supply connected to a transformer and the provided lamps are placed on the lamp bases according to the invention and the entire device is ready for operation.

In Fig. 9 ist ein Ausführungsbeispiel eines Lampenfusses 4 dargestellt; in Fig. 9a eine Seitenansicht ohne Verkleidung, in Richtung der Achse der Stromschiene gesehen, in Fig. 9b von unten her gesehen. Der Lampenfuss besteht aus einer isolierenden Grundplatte 20, mit der zwei elektrisch leitende Dauermagnete 21 mechanisch verbunden sind, beispielsweise durch zwei Niete 22. Zwischen die Grundplatte 20 und die Magnete 21 ist eine dünne Platte 25 aus einem Elastomer eingeschoben, womit Ungenauigkeiten in den Dauermagneten 21, Unebenheiten der Stahlbänder 8 und allfälliger Verzug der Grundplatte 20 aufgenommen werden kann. Die oberen Köpfe der Niete 22 sind zugleich als Kabelschuhe ausgebildet, in denen je ein Draht 23 festgeklemmt oder -gelötet ist. Mit der Grundplatte 20 verbunden, beispielsweise durch eine Schraubverbindung oder durch Schweissen, ist der bereits in Fig. 1 beschriebene Stiel 5, in welchem die Drähte 23 verlaufen. Der beschriebene Lampenfuss 4 wird auf die bereits aus Fig. 4 bekannte Stromschiene aufgesetzt und haftet nun mit magnetischer Kraft auf den Stahlbändern 8. Die Dauermagnete 21 stellen gleichzeitig den elektrischen Kontakt mit den stromführenden Stahlbändern 8 her. Die magnetische Kraft, die von den Dauermagneten 21 auf den Stahlbändern 8 entwickelt wird, ist - durch geeignete Wahl der Dauermagnete - so gross, dass das Gewicht der Lampe, die am Lampenfuss befestigt ist, in jeder Lage getragen wird.9 shows an exemplary embodiment of a lamp base 4; in Fig. 9a a side view without cladding, seen in the direction of the axis of the busbar, in Fig. 9b seen from below. The lamp base consists of an insulating base plate 20, to which two electrically conductive permanent magnets 21 are mechanically connected, for example by means of two rivets 22. A thin plate 25 made of an elastomer is inserted between the base plate 20 and the magnets 21, with inaccuracies in the permanent magnets 21 , Unevenness of the steel strips 8 and any distortion of the base plate 20 can be absorbed. The upper heads of the rivets 22 are also designed as cable lugs, in each of which a wire 23 is clamped or soldered. Connected to the base plate 20, for example by a screw connection or by welding, is the handle 5 already described in FIG. 1, in which the wires 23 run. The lamp base 4 described is placed on the busbar already known from FIG. 4 and now adheres to the steel strips 8 with magnetic force. The permanent magnets 21 simultaneously establish electrical contact with the current-carrying steel strips 8. The magnetic force which is developed by the permanent magnets 21 on the steel strips 8 is - by suitable selection of the permanent magnets - so great that the weight of the lamp, which is attached to the lamp base, is borne in any position.

Die Einspeisung des Stromes in die Stromschiene geschieht durch eine dem Lampenfuss gemäss Fig. 9 identische Vorrichtung. Der Stiel 5 braucht selbstverständlich nicht senkrecht auf der Ebene der Grundplatte 20 zu stehen, sondern kann - mittels geeigneter Ausgestaltung der Grundplatte 20 - in irgend eine passende Richtung geführt werden. Damit ist mit Lampenfuss jeweils auch die aufbaumässig identische Stromeinspeisung gemeint und beschrieben.The current is fed into the busbar by a device which is identical to the lamp base according to FIG. 9. The handle 5 does not of course have to be perpendicular to the plane of the base plate 20, but can - in a suitable configuration of the base plate 20 - be guided in any suitable direction. This means that the base of the electricity supply is identical and described in terms of structure.

Selbstverständlich ist der Lampenfuss 4 gemäss Fig. 9 verkleidet, doch da die technische Wirkung der Verkleidung wesentlich keineres Gewicht hat als die ästhetische, wird hier nicht weiter darauf eingegangen.Of course, the lamp base 4 is clad according to FIG. 9, but since the technical effect of the cladding has essentially no weight than the aesthetic one, it will not be discussed further here.

Der Lampenfuss 4 gemäss Fig. 9 passt technisch zu den Stromschienen-Ausführungsbeispielen der Fig. 2 bis 5. Das Ausführungsbeispiel von Fig. 10, eine Variante zu jenem von Fig. 9 weist - mit der Grundplatte 20 verbunden - einen Kunststoff-Block 10 auf, der in die Vertiefung 13 der Stromschiene 1 gemäss Fig. 6 passt und damit ebenfalls, wie die Erhebung 9. genaues Aufsetzen des Lampenfusses erzwingt.The lamp base 4 according to FIG. 9 technically matches the busbar embodiments of FIGS. 2 to 5. The embodiment of FIG. 10, a variant of that of FIG. 9, has a plastic block 10 connected to the base plate 20 , which fits into the recess 13 of the busbar 1 according to FIG. 6 and thus also, like the elevation 9, forces the lamp base to be put on exactly.

Im Ausführungsbeispiel gemäss Fig. 11 a,b,c trägt die Grundplatte 20 einen einzigen Dauermagneten 24 mit einer einzigen elastomeren Platte 25. Der Dauermagnet 24 braucht nicht elektrisch leitfähig zu sein, da er nur für die Haftung des Lampenfusses 4 auf den Strahlbändern 8 von Fig. 7, 8 zu sorgen hat.In the exemplary embodiment according to FIGS. 11 a, b, c, the base plate 20 carries a single permanent magnet 24 with a single elastomeric plate 25. The permanent magnet 24 does not need to be electrically conductive, since it is only for the adhesion of the lamp base 4 to the beam bands 8 of Fig. 7, 8 has to worry.

Fig. 11a zeigt den Lampenfuss 4 in Aufsicht in Richtung der Stromschiene, Fig. 11b zeigt ihn von der Seite, wobei der Dauermagnet 24 nur punktiert dargestellt ist. Fig. 11c zeigt den Lampenfuss 4 von unten, also von der Stromschiene her. Neben dem Dauermagneten 24, der wiederum beispielsweise mit Nieten 22 an der Grundplatte 20 befestigt ist, trägt diese zwei Kontaktfedern 26. Diese sind an der Grundplatte 20 mit Nieten 27 so befestigt, dass die Nieten 27 einander diagonal gegenüberliegen. Damit wird die magnetische Verbindung von den Anpresskräften der Kontaktfedern 26 gleichmässig beansprucht. Die Befestigung der Drähte 23 an den Nieten 27 ist gleich, wie zu Fig. 12 beschrieben. Der Stiel 5 ist hier an den Rand der Grundplatte 20 verschoben.FIG. 11a shows the lamp base 4 in a top view in the direction of the busbar, FIG. 11b shows it from the side, the permanent magnet 24 being shown only in dotted lines. 11c shows the lamp base 4 from below, that is to say from the busbar. In addition to the permanent magnet 24, which in turn is fastened to the base plate 20, for example with rivets 22, the latter bears two contact springs 26. These are fastened to the base plate 20 with rivets 27 in such a way that the rivets 27 lie diagonally opposite one another. The magnetic connection is thus evenly stressed by the contact forces of the contact springs 26. The attachment of the wires 23 to the rivets 27 is the same as described for FIG. 12. The stem 5 is shifted to the edge of the base plate 20 here.

Mit den Kontaktfedern 26 drückt der Lampenfuss 4 gemäss Fig. 11 auf die blanken Bereiche der Stahlbänder 8 gemäss Fig. 7, 8.11 presses the lamp base 4 according to FIG. 11 onto the bare areas of the steel strips 8 according to FIGS. 7, 8.

Nicht gezeichnet ist eine Variante zu den Fig. 9, 10, 11, bei der die Grundplatte 20 aus Metall gefertigt ist. Die notwendige Isolation der Dauermagnete 21 und/oder Kontaktfedern 26 wird durch Tüllen aus isolierendem Werkstoff bewirkt, durch die die Nieten 22 bzw 27 geführt werden.Not shown is a variant of FIGS. 9, 10, 11, in which the base plate 20 is made of metal. The necessary insulation of the permanent magnets 21 and / or contact springs 26 is effected by grommets made of insulating material through which the rivets 22 and 27 are guided.
