Abstract

The lamp is provided with an angled strip (1) with two side-pieces (2, 3) arranged at an angle to one another, to which are secured tubular lamps (6) arranged in a row. On at least one side-piece are fixed conductor paths (4, 5) which extend over the full longitudinal extent of the angled strips. Electrically conductive support elements (7) are secured to the insides of the side-pieces, forming the electrical connection with the conductor paths and holding the tubular lamps in position. The lamp forms an extremely simple lighting strip which can be supplied by the metre. Despite its extremely small dimensions it offers a high lighting power and is suitable for and adaptable to a very wide range of applications. Of particular advantage is the fact that the lamp can be used at the same time as a corner element for connecting two wall elements arranged at an angle to one another. Consequently the lamp can serve both as a lighting unit and also as a constructional element.

Description

Die Erfindung betrifft eine Leuchte mit in Reihe angeordneten Soffittenlampen, einer Winkelleiste mit zwei zueinander in einem Winkel (α) angeordneten Schenkeln, Leitungsbahnen, die an wenigstens einem Schenkel angebracht sind und jeweils durchgehend in Längsrichtung der Winkelleisten verlaufen, sowie elektrisch leitenden Soffittenlampen-Halterungselementen, die auf den Innenseiten der Schenkel mittels Nietverbindungen befestigt sind, wobei die Nietverbindungen gleichzeitig die elektrische Verbindung zwischen den jeweiligen Leiterbahnen und dem Halterungselement darstellen, wobei die Halterungselemente jeweils abwelchselnd mit je einer der Leiterbahnen elektrisch verbunden sind, und wobei die Halterungselemente Löcher aufweisen, in denen die konisch zulaufenden Kontaktenden der Soffittenlampen bei gleichzeitiger Stromzuführung an den Kontaktenden in ihrer Lage gehalten werden.The invention relates to a luminaire with tubular lamps arranged in a row, an angle bar with two legs arranged at an angle (α) to one another, conduction paths which are attached to at least one leg and each run continuously in the longitudinal direction of the angle bars, and electrically conductive tubular lamp holder elements, which are fastened on the inner sides of the legs by means of rivet connections, the rivet connections simultaneously representing the electrical connection between the respective conductor tracks and the mounting element, the mounting elements being alternately electrically connected to one of the conductor tracks, and the mounting elements having holes in which the conically tapered contact ends of the festoon lamps are held in position with simultaneous power supply to the contact ends.

Eine Leuchte dieser Art ist beispielsweise aus CH-A-599 501 bekannt. Für jede Soffittenlampe sind dabei jeweils zwei Halterungselemente - für jede Seite der Soffittenlampen jeweils eines - vorgesehen, zwischen denen die Soffittenlampen eingesetzt sind. Jeweils benachbarte Halterungselemente sind dabei an unterschiedlichen Schenkeln der Winkelleiste befestigt. Für jede Soffittenlampe müssen also zwei Halterungselemente vorgesehen sein, die an den Leiterbahnen befestigt werden müssen. Die Leiterbahnen sind dabei an der Innenseite der Schenkel, also in unmittelbarer Nähe der Soffittenlampen angebracht, so daß diese durch Konvektion oder und Strahlungsübergang auf eine relativ hohe Temperatur aufgeheizt werden. Die Schenkel, an denen die Leiterbahnen befestigt sind, sind aus einem nicht leitenden, elektrisch isolierenden Material, beispielsweise Kunststoff, deren Wärmeleitfähigkeit sehr gering ist, so daß die Temperatur, auf die die metallischen Leiterbahnen aufgeheizt werden, nur wenig unterhalb der Soffittenlampentemperatur liegen. Aufgrund der sich erheblich unterscheidenden Wärmeausdehnungskoeffizienten der metallischen Leiterbahn und des isolierenden Schenkelmaterials, an dem die Leiterbahn starr befestigt ist, entstehen starke mechanische Spannungen, die bewirken, daß sich die Leuchte wellt und verwirft oder gar ein Bruch auftreten kann. Es besteht auch die Möglichkeit, daß die Verbindung zwischen metallischer Leiterbahn und isolierendem Schenkelmaterial bricht. In jedem Fall ist die Leuchte aufgrund der thermischen Gegebenheiten mechanisch instabil, was insbesondere die Zuverlässigkeit und Lebensdauer dieser bekannten Leuchte erheblich reduziert.A lamp of this type is known for example from CH-A-599 501. Two mounting elements are provided for each festoon lamp - one for each side of the festoon lamps - between which the festoon lamps are inserted. Adjacent mounting elements are attached to different legs of the angle bar. For each festoon lamp, two mounting elements must be provided, which must be attached to the conductor tracks. The conductor tracks are attached to the inside of the legs, that is to say in the immediate vicinity of the tubular lamps, so that they are heated to a relatively high temperature by convection or by radiation transfer. The legs to which the conductor tracks are attached are made of a non-conductive, electrically insulating material, for example plastic, whose thermal conductivity is very low, so that the temperature to which the metallic conductor tracks are heated is only slightly below the temperature of the festoon lamp lie. Due to the significantly different coefficients of thermal expansion of the metallic conductor track and the insulating leg material to which the conductor track is rigidly attached, strong mechanical stresses occur, which cause the lamp to curl and warp or even break. There is also the possibility that the connection between the metallic conductor track and the insulating leg material breaks. In any case, the luminaire is mechanically unstable due to the thermal conditions, which in particular considerably reduces the reliability and service life of this known luminaire.

Ferner sind aus WO-A-85/05433 und aus EP-A-0 126 023 Leuchten in Form einer Winkelleiste mit Soffittenlampen bekannt, bei denen wiederum je zwei Halterungselemente für jeweils eine Soffittenlampe vorgesehen sind. Die Halterungselemente sind dabei einstückig mit den Leiterbahnen ausgebildet, wobei die Halterungselemente aus den Leiterbahnen ausgebrochen sind. Die Leiterbahn ist jeweils auf die Außenseiten der Schenkel aufgelegt und die Halterungselemente ragen durch jeweils ein entsprechendes Loch in den Innenraum der Leuchte hinein. Ein Nachteil dieser Leuchte besteht darin, daß die Leiterbahnen durch das Ausbrechen der Halterungselemente aus dem Leiterbahnmaterial in ihrem Leitungsquerschnitt an diesen Stellen sehr stark reduziert werden. Dies bedeutet, daß die Leuchte nur mit einer geringen Stromstärke betrieben werden kann, was insbesondere deshalb von großem Nachteil ist, weil derartige Leuchten üblicherweise im Niedervoltbereich betrieben werden müssen und für eine entsprechende Leistung hohe Stromstärken erforderlich sind. Darüber hinaus ist es bei den bekannten Leuchten nachteilig, daß eine Anpassung derselben auf Soffittenlampen mit unterschiedlichen Längen oder Durchmessern schwierig ist. Für jede Art einer Soffittenlampe müssen jeweils individuelle Werkzeuge sowohl für die Leiterbahnherstellung als auch für die Winkelleistenherstellung vorgesehen sein, um die Leiterbahnen mit den entsprechenden Ausbrüchen zur Herstellung der Halterungselemente und die Winkelleiste mit entsprechenden Löchern für den Durchgang der Halterungselemente zu versehen. Darüber hinaus ist der Herstellungsaufwand solcher Leisten erheblich, da Stanzwerkzeuge für die Ausbrechung der Halterungselemente aus den Leiterbahnen erforderlich sind und in den Schenkeln Löcher sowohl für den Durchgang der Halterungselemente als auch für Befestigungselemente, wie Nieten usw., eingestanzt werden müssen.Furthermore, from WO-A-85/05433 and from EP-A-0 126 023 lamps in the form of an angle bar with festoon lamps are known, in which in turn two mounting elements are provided for each festoon lamp. The mounting elements are formed in one piece with the conductor tracks, the mounting elements having broken out of the conductor tracks. The conductor track is placed on the outside of the legs and the mounting elements protrude through a corresponding hole in the interior of the lamp. A disadvantage of this luminaire is that the conductor cross-sections are very greatly reduced in their conductor cross-section at these points by breaking out the mounting elements from the conductor material. This means that the lamp can only be operated with a low current, which is particularly disadvantageous because such lamps usually have to be operated in the low-voltage range and high currents are required for a corresponding output. In addition, it is disadvantageous in the known lamps that it is difficult to adapt them to festoon lamps with different lengths or diameters. For each type of festoon lamp, individual tools must be provided, both for the production of conductor tracks and for the manufacture of corner strips be to provide the conductor tracks with the corresponding cutouts for the manufacture of the mounting elements and the angle bar with corresponding holes for the passage of the mounting elements. In addition, the production effort of such strips is considerable, since punching tools are required for the breakout of the mounting elements from the conductor tracks and holes in the legs for the passage of the mounting elements as well as for fastening elements such as rivets etc. have to be punched.

Aus der FR-A-331 441 ist eine Leuchte bekannt, bei der zwei Leiter vorgesehen sind, die sich parallel zur Leuchte erstrekken. Darüberhinaus weist die Leuchte Halterungselemente auf, die zwei Laschen zum Haltern von jeweils einem Ende zweier Soffittenlampen aufweisen, und die an einem Gehäuse isoliert befestigt sind. Von diesen Halterungselementen führen Leitungsdrähte zu den der Leuchte parallel liegenden Leitungen. Die einzelnen Halterungselemente bestehen ihrerseits aus verschiedenen Elemententeilen, die über Schrauben miteinander und an weiteren Lampenteilen befestigt sind. Der Fertigungsaufwand für die einzelnen Teile des Halterungselements sowie die Montage derselben sind sehr zeitraubend und aufwendig. Darüberhinaus ist von jedem Halterungselement zusätzlich eine Verbindungsleitung zu den der Leuchte parallel laufenden Leitungen erforderlich, die den Herstellungsaufwand weiter erhöhen und insbesondere auch die Betriebssicherheit dieser bekannten Leuchte beeinträchtigt.A lamp is known from FR-A-331 441, in which two conductors are provided which extend parallel to the lamp. In addition, the luminaire has mounting elements which have two tabs for holding one end of two tubular lamps each and which are fastened in an insulated manner to a housing. From these mounting elements lead wires lead to the leads lying parallel to the lamp. The individual mounting elements in turn consist of various element parts that are fastened to each other and to other lamp parts by screws. The manufacturing effort for the individual parts of the mounting element and the assembly of the same are very time-consuming and complex. In addition, a connection line to the lines running parallel to the lamp is additionally required from each mounting element, which further increases the manufacturing outlay and in particular also affects the operational safety of this known lamp.

Aus der US-A-1 484 211 ist eine in Form einer Winkelleiste ausgebildete Leuchte mit Lampen bekannt, die in speziell für die nicht näher bezeichneten Lampen ausgebildet sind und im wesentlichen den vollen Durchmesser in einem aus Seitenwänden gebildeten O-förmigen Gebilde einnehmen. Durch diese Sockel zur Befestigung der Lampen wird der Lampenraum in einzelne Segmente aufgeteilt, so daß über die Lampe hinweg keine gleichmäßige Ausleuchtung möglich ist, sondern dunkle Bereiche an diesen Stellen mit den Sockeln auftreten. Darüberhinaus sind die Sockel sehr aufwendig. Die elektrischen Leitungen sind innerhalb des Winkeldreiecks angeordnet. Diese Leuchtenanordnung ist hinsichtlich ihrer Einzelteile ohne ersichtliche Vorteile sehr aufwendig und für eine kostengünstige Herstellung von Leuchten als Massenware nicht geeignet.From US-A-1 484 211 a luminaire in the form of an angular strip is known with lamps which are specially designed for the unspecified lamps and which essentially occupy the full diameter in an O-shaped structure formed from side walls. By means of this base for fastening the lamps, the lamp space is divided into individual ones Segments divided so that no uniform illumination is possible across the lamp, but dark areas appear at these points with the bases. In addition, the bases are very complex. The electrical lines are arranged within the triangle. This luminaire arrangement is very complex in terms of its individual parts without obvious advantages and is not suitable for mass production of luminaires at low cost.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Leuchte der eingangs genannten Art zu schaffen, die in einfachster Weise hergestellt werden kann, bei gegebenem Materialaufwand mit einer größtmöglichsten Stromstärke betrieben werden kann und auf einfache Weise an verschiedene Soffittenlampen-Größen anpaßbar ist.The invention is therefore based on the object of providing a luminaire of the type mentioned at the outset, which can be produced in the simplest manner, can be operated with the greatest possible amperage for a given amount of material and can be easily adapted to different sizes of festoon lamps.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Halterungselemente jeweils zwei federnde Laschen aufweisen, daß je ein Halterungselement zum Haltern von jeweils einem Ende zweier Soffittenlampen dient, und daß die Leiterbahnen an der Schenkel-Außenseite bzw. an den Schenkel-Außenseiten vorgesehen sind.This object is achieved in that the mounting elements each have two resilient tabs, that a mounting element is used to hold one end of each two tubular lamps, and that the conductor tracks are provided on the outside of the leg or on the outside of the leg.

Aufgrund des erfindungsgemäßen Merkmals, daß die Halterungselemente jeweils zwei federnde Laschen zum Haltern von jeweils einem Ende zweier Soffittenlampen aufweisen, ist es möglich, für jede Soffittenlampe im Mittel jeweils nur ein Halterungselement vorzusehen.Due to the feature according to the invention that the mounting elements each have two resilient tabs for mounting one end of each of two tubular lamps, it is possible to provide only one mounting element on average for each tubular lamp.

Ein Vorteil besteht darin, daß die Fertigung sehr einfach ist, da nur relativ wenig Halterungselemente angebracht werden müssen. Zusätzliche Befestigungsmaßnahmen zum Befestigen der Leiterbahn sind nicht erforderlich, da die Befestigungselemente, beispielsweise Nietverbindungen, zur Befestigung der Halterungselemente gleichzeitig auch der Befestigung der Leiterbahnen an den Schenkeln dienen. Aufgrund der einfachen Art der Montage und der Befestigung der einzelnen Elemente aufgrund der erfindungsgemäßen Halterungselemente zum Haltern von jeweils einem Ende zweier Soffittenlampen ist es äuch möglich, die Winkelleisten auf einfache Art für unterschiedliche Abmessungen von Soffittenlampen auszubilden. Für längere Soffittenlampen brauchen lediglich die Abstände bei der Vernietung der Halterungselemente mit den Schenkeln bzw. den Leitungsbahnen vergrößert werden. Werden Soffittenlampen mit größerem oder kleinerem Durchmesser verwendet, so werden lediglich andere Halterungselemente mit entsprechend längeren oder kürzeren Laschen benutzt.One advantage is that the production is very simple since only relatively few mounting elements have to be attached. Additional fastening measures for fastening the conductor track are not necessary, since the fastening elements, for example rivet connections, also serve to fasten the mounting elements to the fastening of the conductor tracks to the legs. Because of the simple type of assembly and the fastening of the individual elements due to the mounting elements according to the invention for holding one end of two festoon lamps each, it is also possible to design the angle strips in a simple manner for different dimensions of festoon lamps. For longer festoon lamps, only the distances when riveting the mounting elements to the legs or the conductor tracks need to be increased. If festoon lamps with a larger or smaller diameter are used, only other mounting elements with correspondingly longer or shorter tabs are used.

In Verbindung mit den übrigen Merkmalen der Erfindung ist es insbesondere auch vorteilhaft, wenn die Leitungsbahnen an der Schenkel-Außenseite bzw. an den Schenkel-Außenseiten vorgesehen sind, da das elektrisch isolierende Schenkelmaterial, vorzugsweise ein Kunststoff, als thermische Trennung der Leitungsbahnen von den Soffittenlampen dient.In connection with the other features of the invention, it is particularly advantageous if the conductor tracks are provided on the outside of the leg or on the outside of the leg, since the electrically insulating leg material, preferably a plastic, as a thermal separation of the conductor tracks from the tubular lamps serves.

Weiterhin wird das Risiko vermindert, daß etwa durch leitende Gegenstände, die auf die Lichtleiste fallen, Kurzschlüsse entstehen, da die Außenseiten der Schenkel üblicherweise an Mauern, Wänden usw. befestigt und dadurch die Leitungsbahen abgedeckt und geschützt sind.Furthermore, the risk is reduced that, for example, short-circuits are caused by conductive objects falling on the light strip, since the outer sides of the legs are usually fastened to walls, walls, etc. and the cable trays are thereby covered and protected.

Mit den erfindungsgemäßen Merkmalen ergibt sich also eine denkbar einfache Leuchte, die je nach den vorliegenden Gegebenheiten in jeder Länge praktisch als Meterware benutzt oder installiert werden kann, etwa als Schaufenster-, Caravan- oder Bootsbeleuchtung, als Hinterleuchtung von Stukkaturwerk und Unterzügen, als indirekte Raumbeleuchtung oder Handlaufleuchte, als Regal- oder Vitrinenleuchte, als Schrankleuchte, Spiegelleuchte, Treppenlicht oder Hängeschrankleuchten für Küchen, für die Anwendung in Innen- oder Außenräumen usw. Der Benutzer braucht die Leuchte für die jeweilige Anpassung lediglich wie Meterware ablängen und anbringen und ist nicht auf fertige, in ihren bemessungen festgelegte Leuchten angewiesen.With the features according to the invention, this results in a very simple luminaire which, depending on the circumstances, can be used or installed in any length practically by the meter, for example as shop window, caravan or boat lighting, as backlighting of stucco work and beams, as indirect room lighting or handrail light, as a shelf or showcase light, as a cabinet light, mirror light, staircase light or hanging cupboard light for kitchens, for use in indoor or outdoor spaces etc. The user only needs to cut and attach the light for the respective adjustment as by the meter and is not ready , instructed in their dimensioned luminaires.

Die Leitungsbahnen für die beiden elektrischen Phasen zur elektrischen Versorgung der Soffittenlampen befinden sich gemäß einer Ausgestaltung der Erfindung voneinander isoliert auf einem Schenkel der Winkelleiste. Besonders vorteilhaft ist es jedoch, auf je einem Schenkel der Winkelleiste je eine der beiden durchgehenden Leitungspaare anzubringen. Dadurch ist die Möglichkeit eines Kurzschlusses im wesentlichen ausgeräumt bzw. es sind keine Maßnahmen erforderlich, Isolationen zwischen den Leitungspaaren vorzusehen, um Kurzschlüsse sicher zu verhindern.According to one embodiment of the invention, the conductor tracks for the two electrical phases for the electrical supply of the festoon lamps are isolated from one another on one leg of the angle strip. However, it is particularly advantageous to attach one of the two continuous line pairs to one leg of the angle strip. As a result, the possibility of a short circuit is essentially eliminated or no measures are required to provide insulation between the line pairs in order to reliably prevent short circuits.

Für die Fertigung der erfindungsgemäßen Leuchte ist es von Vorteil, wenn die Halterungselemente mittels jeweils wenigstens einer Nietverbindung an den Schenkeln befestigt sind, wobei die Nietverbindung gleichzeitig die elektrische Verbindung zwischen der jeweiligen Leitungsbahn und dem Halterungselement darstellt. Die Fertigung derartiger Lichtleisten ist auf diese Weise äußert effektiv und kostengünstig.For the manufacture of the lamp according to the invention, it is advantageous if the mounting elements are fastened to the legs by means of at least one rivet connection, the rivet connection simultaneously being the electrical one Connection between the respective track and the support member represents. The production of such light strips is extremely effective and inexpensive in this way.

Vorzugsweise beträgt der Winkel α gleich 90°. Obgleich der Winkel beliebig und gemäß der jeweiligen Anwendungsfälle frei gewählt werden kann, ist es für die meisten Fälle von Vorteil, daß der Winkel gleich 90° ist. Grundsätzlich ist es auch möglich, eine gerade Leiste, ohne Schenkel, also keine Winkelleiste, vorzusehen. Die Winkelleiste mit Schenkeln ergibt jedoch eine mechanisch wesentlich steifere und stabilere Leuchte, die insbesondere auch eine gefällige Form darstellt.The angle α is preferably 90 °. Although the angle can be chosen arbitrarily and according to the respective application, it is advantageous in most cases that the angle is 90 °. In principle, it is also possible to provide a straight strip without a leg, that is to say no angled strip. The angle bar with legs, however, results in a mechanically much stiffer and more stable lamp, which in particular also represents a pleasing shape.

Gemäß einer besonders vorteilhaften Ausführungsform der Erfindung ist die Leuchte als Winkelelement für die Verbindung zweier in einem Winkel zueinander angeordneter Randelemente vorgesehen. Auf diese Weise bildet die Leuchte selbst ein Bau- bzw. Verbindungselement für die mechanische Verbindung von Wandelementen, so daß die Leuchte zwei Funktionen erfüllt, nämlich als mechanisches Bauelement einerseits und als Leuchte andererseits. Diese Kombination ist von besonderem Vorteil, da nunmehr jedermann auf einfachste Weise durch die Verbindung von Wand-, Glas- oder Spiegel-Elemeneten Vitrinen, Raumformen oder Behältnisse beliebiger Abmessungen mit der erfindungsgemäßen Leuchte selbst zusammen- und herstellen kann, wobei das Winkelelement gleichzeitig als Beleuchtungskörper dient und nicht nur ansprechend, sondern auch beleuchtungstechnisch sehr effektiv eine Ausleuchtung des zusammengestellten Elements oder Behältnisses ermöglicht. Für ein quadratisches oder rechteckiges Raumelement werden Leuchten mit einem Winkel α von 90° verwendet, wogegen für ein achteckiges Raumelement Leuchten als Winkelelement mit einem Winkel α von 135° Verwendung finden. Beispielsweise ist es auch möglich, mit Winkel versehene Glas-, Spiegel- oder sonstige Wände, etwa Zickzackwände, auf diese Weise mit den Leuchten als Winkelelelemente auf einfache Weise zusammenzusetzen und zu kombinieren, wobei die als mechanische Verbindungselemente dienenden Winkel erfindungsgemäß als Beleuchtungskörper dienen.According to a particularly advantageous embodiment of the invention, the luminaire is provided as an angle element for connecting two edge elements arranged at an angle to one another. In this way, the lamp itself forms a component or connecting element for the mechanical connection of wall elements, so that the lamp fulfills two functions, namely as a mechanical component on the one hand and as a lamp on the other. This combination is particularly advantageous, since anyone can now easily assemble and manufacture showcases, room shapes or containers of any dimensions with the luminaire according to the invention by connecting wall, glass or mirror elements, the angle element being used simultaneously as a lighting fixture serves and not only in an appealing manner, but also in terms of lighting technology very effectively enables illumination of the assembled element or container. Luminaires with an angle α of 90 ° are used for a square or rectangular room element, whereas luminaires are used as an angle element with an angle α of 135 ° for an octagonal room element. For example, it is also possible to easily assemble and combine glass, mirror or other walls, such as zigzag walls, with the luminaires as angular elements in this way, the angles serving as mechanical connecting elements serving according to the invention as lighting elements.

Eine weitere Ausgestaltung der erfindungsgemäßen Leuchte besteht darin, daß an bzw. in der Nähe der Winkelenden Einrichtungen zur Befestigung einer lichtdurchlässigen Abdeckleiste vorgesehen sind. Die Befestigungseinrichtungen können beispielsweise Nuten sein, in denen die Abdeckleisten eingeschoben sind, es können jedoch auch Klipp- oder Schnappeinrichtungen verwendet werden. Durch die lichtdurchlässige Abdeckleiste, beispielsweise eine Milchglas ähnliche Kunststoffleiste ergibt sich ein diffuseres, gleichmäßigeres Licht, das für bestimmte Anwendungsfälle geeigneter ist als das direkte Licht aus den Soffittenlampen.A further embodiment of the luminaire according to the invention is that devices for fastening a translucent cover strip are provided on or in the vicinity of the angle ends. The fastening devices can, for example, be grooves in which the cover strips are inserted, but clip or snap devices can also be used. The translucent cover strip, for example a plastic strip similar to milk glass, results in a more diffuse, more uniform light which is more suitable for certain applications than the direct light from the festoon lamps.

Für bestimmte Anwendungsfälle ist es vorteilhaft, daß die Leuchte eine Verblendung aufweist, so daß nicht direkt in die Soffittenlampen gesehen wird. Gemäß einer weiteren Ausführungsform der Erfindung sind dazu an bzw. in der Nähe der Schenkelenden Einrichtungen zur Befestigung einer derartigen Verblendung entsprechend den Befestigungseinrichtungen für eine Abdeckleiste vorgesehen.For certain applications, it is advantageous for the lamp to have a cover so that it is not viewed directly into the tubular lamps. According to a further embodiment of the invention, devices for fastening such a covering corresponding to the fastening devices for a cover strip are provided on or near the leg ends.

Eine weitere Ausführungsform der Erfindung besteht darin, die Leuchte in einer Vorrichtung zur abnehmbaren Befestigung an Spiegeln, Gläsern, Bildern usw. vorzusehen. Die abnehmbare Vorrichtung, die die erfindungsgemäße Leuchte trägt, kann beispielsweise auf den zu beleuchtenden Gegenstand mittels einer klemmenartigen Vorrichtung aufsteckbar sein.Another embodiment of the invention is to provide the lamp in a device for removable attachment to mirrors, glasses, pictures, etc. The removable device, which carries the lamp according to the invention, can for example be plugged onto the object to be illuminated by means of a clamp-like device.

Um das von den Soffittenlampen ausgestrahlte Licht optimal ausnutzen und auf einen Gegenstand richten zu können, sind gemäß einer bevorzugten Ausführungsform die Innenseiten der Winkelleiste verspiegelt. Es ist jedoch auch möglich, die Winkelleiste aus einem lichtdurchlässigen Kunststoff zu fertigen, wodurch ein besonderer Effekt besteht.In order to be able to optimally utilize the light emitted by the festoon lamps and to direct it towards an object, the inside of the angle bar is mirrored in accordance with a preferred embodiment. However, it is also possible to manufacture the angle bar from a translucent plastic, which creates a special effect.

Vorzugsweise wird die Leuchte mit Niedervolt betrieben, so daß keine Maßnahmen getroffen werden müssen, um Leitungsbahnen, Anschlüsse oder die Soffittenlampen selbst vor Berührung zu schützen.The lamp is preferably operated at low voltage, so that no measures have to be taken to protect the conductor tracks, connections or the festoon lamps themselves from being touched.

Die Erfindung wird nachstehend anhand der Zeichnungen beispielsweise näher erläutert. Es zeigen:

  • Fig. 1 ein Ausführungsbeispiel der Erfindung in perspektivischer Darstellung,
  • Fig. 2 das in Fig. 1 dargestellte Ausführungsbeispiel in Seitenansicht und
  • Fig. 3 ein Ausführungsbeispiel für eine Vorrichtung, die die erfindungsgemäße Leuchte haltert und als Spiegelleuchte dient,
  • Fig. 4 die erfindungsgemäße Leuchte als Winkelverbindung.
The invention is explained in more detail below with reference to the drawings, for example. Show it:
  • 1 shows an embodiment of the invention in perspective view,
  • Fig. 2 shows the embodiment shown in Fig. 1 in side view
  • 3 shows an exemplary embodiment of a device which holds the lamp according to the invention and serves as a mirror lamp,
  • Fig. 4 shows the lamp according to the invention as an angular connection.

Das in Fig. 1 perspektivisch und in Fig. 2 in einer Seitenansicht dargestellte Ausführungsbeispiel einer erfindungsgemäßen Leuchte weist eine Winkelleiste 1 auf, die zwei Schenkel 2, 3 besitzt. Die Schenkel 2, 3 schließen einen Winkel α ein (vgl. Fig. 2), der im vorliegenden Ausführungsbeispiel 90° beträgt. Die Schenkel 2, 3 sind nicht bis zum Schnittpunkt ausgeführt, sondern mittels eines Querteils 40 verbunden. Die Winkelleiste besteht beispielsweise aus einem Kunststoffmaterial, etwa aus weißem oder glasklarem Macrolon.The embodiment of a luminaire according to the invention shown in perspective in FIG. 1 and in a side view in FIG. 2 has an angle strip 1 which has two legs 2, 3. The legs 2, 3 enclose an angle α (see FIG. 2), which is 90 ° in the present exemplary embodiment. The legs 2, 3 are not made up to the intersection, but are connected by means of a cross member 40. For example, the angle bar consists of a plastic material, such as white or crystal-clear Macrolon.

Auf der Außenseite der Schenkel 2, 3 sind Leitungsbahnen 4, 5 für die Stromversorgung der Stoffittenlampen 6 vorgesehen. Die Leiterbahnen 4 und 5 verlaufen über die gesamte Länge der Lichtleiste. Bei dem dargestellten Ausführungsbeispiel sind die Leitungsbahnen im Material der Winkelleiste 1 auf den Außenseiten der Schenkel 2 und 3 eingelassen.On the outside of the legs 2, 3 there are conduction paths 4, 5 provided for the power supply of the substance lamps 6. The conductor tracks 4 and 5 run over the entire length of the light bar. In the exemplary embodiment shown, the conductor tracks are embedded in the material of the angle strip 1 on the outer sides of the legs 2 and 3.

Auf den Innenseiten der Schenkel 2, 3 sind Soffittenlampen-Haltungselemente 7 befestigt, die jeweils zwei federnde Laschen 8 aufweisen. An den Außenenden der federnden Laschen 8 befinden sich jeweils Löcher 9, deren Durchmesser so gewählt ist, daß die konisch zulaufenden Enden 10 der Soffittenlampen 6 teilweise in das Loch hineinragen können. Durch leichtes elastisches Wegdrücken der federnden Laschen können die Soffittenlampen 6 zwischen die federnden Laschen 8 zweier Soffittenlampen-Halterungselemente 7 eingesetzt werden, wobei die Soffittenlampen 6 dann durch die federnden Laschen in ihrer Lage gehalten werden.On the inside of the legs 2, 3, festoon lamp mounting elements 7 are fastened, each of which has two resilient tabs 8. At the outer ends of the resilient tabs 8 there are holes 9, the diameter of which is selected so that the tapered ends 10 of the tubular lamps 6 can partially protrude into the hole. By slightly resiliently pushing away the resilient tabs, the festoon lamps 6 can be inserted between the resilient tabs 8 of two festoon lamp holder elements 7, the festoon lamps 6 then being held in position by the resilient tabs.

Die Soffittenlampen-Haltungselemente 7 sind jeweils abwechselnd an den beiden Schenkeln 2 bzw. 3 befestigt. Die Halterungselemente 7 stehen mit der jeweiligen Leitungsbahn 4 bzw. 5 in Verbindung. Wie aus Fig. 2 zu ersehen ist, ist das Soffittenlampen-Haltungselement 7 mittels einer Niete 11 am Schenkel 3 befestigt, wobei die Niete gleichzeitig den elektrischen Kontakt zwischen der Leiterbahn 5 und dem Halterungselemeng 7 bildet. Vorzugsweise ist die Niete 11 auf der Außenseite des Schenkels 5 versenkt angeordnet (wie dies in Fig. 2 nicht dargestellt ist), damit die Außenseite des Schenkels 3 bei Befestigung der Lichtleiste an einer Wand plan und satt aufliegt.The festoon lamp holder elements 7 are alternately fastened to the two legs 2 and 3, respectively. The support elements 7 are connected to the respective conductor track 4 or 5. As can be seen from FIG. 2, the tubular lamp holder element 7 is fastened to the leg 3 by means of a rivet 11, the rivet simultaneously forming the electrical contact between the conductor track 5 and the holder element 7. The rivet 11 is preferably arranged sunk on the outside of the leg 5 (as is not shown in FIG. 2) so that the outside of the leg 3 lies flat and snug when the light bar is attached to a wall.

Die Halterungselemente 7 sind jeweils abwechselnd an den beiden Schenkeln 2 bzw. 3 befestigt und stehen damit abwechselnd mit den Leitungsbahnen 4 bzw. 5 in Verbindung.The mounting elements 7 are alternately fastened to the two legs 2 and 3 and are thus alternately connected to the conductor tracks 4 and 5.

Dadurch ergibt sich eine Parallelschaltung der Soffittenlampen 6, so daß bei Ausfall bzw. Durchbrennen einer Soffittenlampe die anderen weiter brennen.This results in a parallel connection of the festoon lamps 6, so that if one of the festoon lamps fails or burns out, the others continue to burn.

Fig. 3 zeigt die Anwendung der erfindungsgemäßen Leuchte in Zusammenhang mit einer Spiegelleuchte. Die dafür vorgesehene Vorrichtung 31 gemäß Fig. 3 weist einen rechteckförmigen, auf einer Längsseite offenen Raum 32 auf. Am Ende der kurzen Seitenwände 36, 37 des offenen Raums 32 befinden sich auf der Innenseite Ausnehmungen 33 zur Aufnahme und Halterung der erfindungsgemäßen Leuchte.Fig. 3 shows the application of the lamp according to the invention in connection with a mirror lamp. The device 31 provided for this purpose according to FIG. 3 has a rectangular space 32 which is open on one long side. At the end of the short side walls 36, 37 of the open space 32 there are recesses 33 on the inside for receiving and holding the lamp according to the invention.

Bei dieser Ausführungsform der Erfindung ist eine lichtdurchlässige Abdeckleiste 34 vorgesehen, die Vorsprünge 39 aufweist, zwischen die die Leuchte 1 elastisch eingesetzt ist. Die Schenkelenden 38 der Leuchte 1 sind dafür an der Außenseite etwas abgeflacht, wie dies aus Fig. 3 ersichtlich ist.In this embodiment of the invention, a translucent cover strip 34 is provided, which has projections 39, between which the lamp 1 is inserted elastically. For this purpose, the leg ends 38 of the lamp 1 are somewhat flattened on the outside, as can be seen in FIG. 3.

Die Abdeckleiste 34 mit der daran angeklemmten Leuchte 1 wird dann in die Ausnehmungen 33 der Schenkel 36 und 37 der Halterungsvorrichtung 31 elastisch eingedrückt bzw. eingesetzt.The cover strip 34 with the lamp 1 clamped thereon is then elastically pressed or inserted into the recesses 33 of the legs 36 and 37 of the holding device 31.

Die in Fig. 3 dargestellte lichtdurchlässige Abdeckleiste 34 kann mit Vorteil insbesondere auch dann in Zusammenhang mit der Leuchte 1 verwendet werden, wenn die Leuchte 1 etwa mit dem Querteil 4 an einer Halterung befestigt ist und die Enden der Schenkel 2 und 3 frei liegen. Die lichtdurchlässige Abdeckleiste 34 besteht dabei vorzugsweise aus einem elastischen Kunststoff, so daß die Abdeckleiste leicht und elastisch an der Leuchte 1 angebracht und von ihr abgenommen werden kann, um etwa Soffitenlampen auszutauschen. Auf diese Weise ergibt sich in einfacher Weise eine Art Baukastensystem mit wenigen Bauteilen, mit denen die Leuchte 1 auf einfachste und kostengünstigste Weise und mittels denkbar geringen Aufwandes, der auch von Laien aufgebracht werden kann, an die verschiedensten Anwendungsformen angepaßt werden kann.The translucent cover strip 34 shown in FIG. 3 can advantageously also be used in connection with the luminaire 1 if the luminaire 1 is fastened to a holder, for example with the transverse part 4, and the ends of the legs 2 and 3 are exposed. The translucent cover strip 34 is preferably made of an elastic plastic, so that the cover strip can be attached to and removed from the light 1 in a light and elastic manner, for example to replace tubular lamps. In this way, a type of modular system with a few components is obtained in a simple manner, with which the lamp 1 can be adapted to the most varied forms of use in the simplest and most cost-effective manner and by means of very little effort, which can also be applied by laypersons.

Die Abdeckleiste kann auf einfache Weise durch leichten Druck auf die Leuchte 1 aufgeschnappt werden.The cover strip can be snapped on by simply pressing light 1.

Der Hauptvorteil der vorliegenden Erfingung, diese als Meterware zu liefern und auf einfachste Weise an die Raum- und Lichtbedürfnisse anzupassen, bleibt daher auch gewahrt, denn auch die Abdeckleiste oder die Halterungsvorrichtung 31 können vom Benutzer auf die von ihm gewünschte Länge ebenso abgeschnitten werden wie die Leuchte 1 selbst.The main advantage of the present invention, to supply it by the meter and to adapt it in the simplest way to the space and light requirements, is also preserved, because the cover strip or the mounting device 31 can also be cut to the desired length by the user, just like that Light 1 itself.

Fig. 4 zeigt eine besonders vorteilhafte Ausführungs- und Anwendungsform der erfindungsgemäßen Leuchte 1 als Winkelelement für die Verbindung zweier in einem Winkel zueinander angeorneter Wandelemente 41 und 42. Im dargestellten Ausführungsbeispiel weisen die Wandelemente 41 und 42 zueinander einen Winkel von 90° auf. Es ist jedoch auch möglich, die Leuchte 1 so auszubilden, daß die Schenkel 2 und 3 der Leuchte 1 einen anderen Winkel als 90°, beispielsweise 135°, je nach dem Anwendungsfall bilden, so daß die Leuchte 1 auch als Winkelelement für die Verbindung zweier Wandelemente eingesetzt werden kann, die in einem anderen Winkel als 90°, beispielsweise in einem Winkel von 135° angeordnet werden sollen.4 shows a particularly advantageous embodiment and application form of the luminaire 1 according to the invention as an angular element for connecting two wall elements 41 and 42 arranged at an angle to one another. In the exemplary embodiment shown, the wall elements 41 and 42 have an angle of 90 ° to one another. However, it is also possible to design the lamp 1 so that the legs 2 and 3 of the lamp 1 form an angle other than 90 °, for example 135 °, depending on the application, so that the lamp 1 is also used as an angle element for connecting two Wall elements can be used which are to be arranged at an angle other than 90 °, for example at an angle of 135 °.

Gemäß der in Fig. 4 dargestellten Ausführungs- und Anwendungsform ist ein gleichschenkliger Außenwinkel 43 vorgesehen, dessen Schenkel im dargestellten Ausführungsbeispiel einen Winkel von 90° einschließen. Die Außenwinkel können beispielsweise aus Metall bestehen. Dieser Außenwinkel wird mit Stehbolzen 44 an der Leuchte 1 derart befestigt,
daß zwischen dem Außenwinkel und der innenseitig montierten Leuchte Seitennute freibleiben, in die die Wandelemente 41 und 42 eingesetzt und festgeklemmt werden. Die Wandelemente 41 und 42 können je nach dem Anwendungsfall Glas- oder Spiegelscheiben oder sonstige Wände aus irgendeinem Material sein. Wie in Fig. 4 dargestellt, sind die Stehbolzen 44 in einem bestimmten Abstand voneinander im Innenwinkel des Aussenwinkels 43 fest angebracht, beispielsweise eingelötet.According to the embodiment and application form shown in FIG. 4, an isosceles outer angle 43 is provided, the legs of which in the illustrated embodiment form an angle of 90 °. The outer angles can be made of metal, for example. This outside angle is fastened to the lamp 1 with stud bolts 44 in such a way that
that between the outer angle and the inside-mounted lamp side groove remain free, in which the wall elements 41 and 42 are inserted and clamped. Depending on the application, the wall elements 41 and 42 can be glass or mirror panes or other walls made of any material. As shown in FIG. 4, the stud bolts 44 are firmly attached, for example soldered, at a certain distance from one another in the inner angle of the outer angle 43.

Auf die Stehbolzen 44 wird dann die Leuchte 1, die entsprechende Löcher aufweist, aufgesteckt. Durch Anziehen einer Mutter 45 werden die Wandelemente 41 und 42 zwischen dem Außenwinkel 43 und der Leuchte 1 fest eingespannt.The lamp 1, which has corresponding holes, is then plugged onto the stud bolts 44. By tightening a nut 45, the wall elements 41 and 42 are firmly clamped between the outer angle 43 and the lamp 1.

Selbstverständlich sind auch andere Befestigungsformen und -einrichtungen für einen Fachmann denkbar, um die Leuchte 1 als Winkelelement für die Konstruktion von Kästen, Vitrinen usw. zu verwenden.Of course, other forms of fastening and devices are also conceivable for a person skilled in the art to use the lamp 1 as an angle element for the construction of boxes, showcases, etc.

In der Nähe der Schenkelenden 2 und 3 der Leuchte 1 sind, wie Fig. 4 zeigt, auf der Innenseite Nuten 46 zur Befestigung einer Abdeckleiste 47 vorgesehen, die ihrerseits entsprechende Vorsprünge zur Befestigung in den Nuten 46 aufweist. Die Deckleiste ist auf einfache Weise lediglich durch Aufdrücken anbringbar und leicht entfernbar, wenn beispielsweise eine durchgebrannte Soffitenlampe ausgewechselt werden soll.In the vicinity of the leg ends 2 and 3 of the lamp 1, as shown in FIG. 4, grooves 46 are provided on the inside for fastening a cover strip 47, which in turn has corresponding projections for fastening in the grooves 46. The cover strip can be attached in a simple manner simply by being pressed on and is easily removable if, for example, a burnt-out tubular lamp is to be replaced.

Mit der in Fig. 4 dargestellten Ausführungs- und Anwendungs- form der Leuchte 1 lassen sich mit äußerst geringen Kosten beleuchtete Schaukästen, Glasvitrinen und sonstige Körper herstellen, wobei der Benutzer bei der Herstellung derartiger Gegenstände in seiner Gestaltung einen denkbar freien Spielraum genießt. Es ergeben sich optimal beleuchtete Raumkörper, Vitrinen usw. wie sie etwa zu Dekorationszwecken, für Ausstellungen, Schaufensterdekorationen usw. besonders geeignet sind. Dabei ist von besonderer Bedeutung, daß die Leuchte äußerst klein und unauffällig dimensioniert ist, wobei sich dennoch eine hohe Lichtleistung ergibt.With the embodiment and application form of the luminaire 1 shown in FIG. 4, illuminated display cases, glass showcases and other bodies can be produced at extremely low cost, the user enjoying a conceivably free scope in the design of such objects. The result is optimally illuminated rooms, showcases, etc., such as are particularly suitable for decorative purposes, for exhibitions, shop window decorations, etc. It is of particular importance that the lamp is extremely small and inconspicuously dimensioned, but there is still a high light output.

Gemäß einer Ausführungsform der Erfindung betragen die Abmessungen der Lichtleiste 1,5 x 3,5 cm, wobei die Länge 4 m und mehr betragen kann. Der Benutzer kann je nach dem Verwendungszweck die Leuchte praktisch wie Meterware ablängen und sie an die gewünschten Verwendungsformen anpassen.According to one embodiment of the invention, the dimensions of the light bar are 1.5 x 3.5 cm, and the length can be 4 m and more. Depending on the intended use, the user can cut the lamp to length practically like yard goods and adapt it to the desired forms of use.

Bei der dargestellten Ausführungsform sind pro 100 cm 20 Soffitenlampen vorgesehen, die je nach Wunsch 5 oder 10 Watt Einzelleistung aufweisen können, so daß sich eine Lichtleistung von 100 oder 200 Watt pro 100 cm ergibt.In the embodiment shown, 20 soffit lamps are provided per 100 cm, which can have 5 or 10 watts of individual power as desired, so that there is a light output of 100 or 200 watts per 100 cm.

Die erfindunsgemäße Leuchte wird vorzugsweise im Niedervoltbereich, etwa mit 6 V, 12 V oder 24 V betrieben, so daß die Leuchte insbesondere auch in Außen- oder Feuchträumen eingesetzt werden kann. Darüberhinaus ist sie deshalb auch für Kinderzimmer besonders geeignet,The lamp according to the invention is preferably operated in the low-voltage range, for example with 6 V, 12 V or 24 V, so that the lamp can also be used in particular in outside or damp rooms. In addition, it is therefore particularly suitable for children's rooms,

Die Verbindung der Leitungsbahnen 4, 5 mit einem Transformator bzw. mit dem Netz kann beispielsweise über Klemmen erfolgen, die an den Enden der Schenkel 2, 3 angesetzt werden und einen elektrischen Kontakt mit den Leitungsbahnen 4 bzw. 5 bilden. Gemäß einer anderen Ausführungsform der Erfindung können am Ende einer Leuchte auch mit den Leitungsbahnen 4 bzw. 5 in Kontakt stehende Stecker vorgesehen sein, über die die Leuchte mit Strom versorgt wird. Für größere Längen ist es möglich, mehrere Schienen mit Kupplungsklemmen oder -steckern elektrisch zu verbinden.The connection of the conductor tracks 4, 5 to a transformer or to the network can, for example, take place via terminals which are attached to the ends of the legs 2, 3 and form an electrical contact with the conductor tracks 4 and 5, respectively. According to another embodiment of the invention, plugs in contact with the conductor tracks 4 and 5 can also be provided at the end of a lamp, via which the lamp is supplied with current. For longer lengths, it is possible to electrically connect several rails with coupling clamps or connectors.
