Description

Die Erfindung betrifft eine Leuchte, die aus einem Stromversorgungsteil, einer stabförmigen Halterung und wenigstens einem daran angeordneten, entlang der Halterung verstellbaren Leuchtenkopf besteht.The invention relates to a lamp which consists of a power supply part, a rod-shaped holder and at least one lamp head arranged thereon and adjustable along the holder.

Leuchten nach dem Oberbegriff des ersten Anspruchs sind beispielsweise als Steh-, Tisch- oder auch als Wandleuchten bekannt. Die Stromversorgung zu dem Leuchtenkopf erfolgt normalerweise über ein elektrisches Kabel, das außerhalb der Halterung entlanggeführt ist. Die Länge des Kabels ist so bemessen, daß es bei der äußersten, von dem Stromversorgungsteil am weitesten entfernten Stellung des Leuchtenkopfes beide Teile miteinander im gespannten Zustand verbindet. Bei Stellung des Leuchtenkopfes in der anderen extremen Lage, dicht an dem Stromversorgungsteil, bildet das Kabel zwischen den zu verbindenden Teilen eine Schlinge, die störend wirkt und eine Gefahrenquelle darstellt (z.B. Hängenbleiben einer vorbeigehenden Person).Luminaires according to the preamble of the first claim are known, for example, as floor, table or wall lights. Power is usually supplied to the lamp head via an electrical cable that runs along the outside of the bracket. The length of the cable is such that it connects the two parts to one another in the tensioned state when the lamp head is in the outermost position, the most distant from the power supply part. When the lamp head is in the other extreme position, close to the power supply part, the cable forms a loop between the parts to be connected, which is disruptive and a source of danger (e.g. getting caught by a person walking by).

Die der Erfindung zugrundeliegende Aufgabe besteht nun darin, einen solchen Nachteil zu vermeiden. Dies wird dadurch erreicht, daß die stabförmige Halterung der Leuchte zwei zueinander parallele Nuten aufweist, in denen versenkt zwei Leisten aus elektrisch-leitendem Material angeordnet sind. Vorteilhafterweise verlaufen die Leisten parallel zur Längsachse der Halterung und sind einander gegenüberliegend angeordnet. Insbesondere ist die Leuchte für Niederspannungsbetrieb vorgesehen. Die vom Stromnetz abgegebene Wechselstromspannung von 220 V bzw. 110 V wird von einem Transformator in einen Gleichstrom von maximal 24 V heruntergeregelt.The object underlying the invention is now to avoid such a disadvantage. This is achieved in that the rod-shaped holder of the lamp has two mutually parallel grooves in which two strips of electrically conductive material are arranged. The strips advantageously run parallel to the longitudinal axis of the holder and are arranged opposite one another. In particular, the luminaire is intended for low-voltage operation. The AC voltage of 220 V or 110 V emitted by the power grid is regulated down to a maximum DC of 24 V by a transformer.

Für die elektrische Kontaktierung der Leisten mit der Stromquelle bzw. dem Transformator ist die Halterung mit einem Ende in eine rohrförmige Aufnahme in dem Stromversorgungsteil der Leuchte eingesetzt und die Leisten wirken mit an der Aufnahme angeordneten Kontaktfedern zusammen.For the electrical contacting of the strips with the power source or the transformer, the holder is inserted at one end into a tubular receptacle in the power supply part of the lamp and the strips interact with contact springs arranged on the receptacle.

Der für die Halterung vorgesehene Leuchtenkopf weist ein Verbindungsteil auf, mittels dem dieser an der Halterung mechanisch befestigt ist, und an dem Kontaktelemente angebracht sind, die ebenfalls mit den Leisten der Halterung zusammenwirken. Vorteilhafterweise umfaßt das Verbindungsteil die Halterung klammerartig und weist Vorsprünge auf, die in die Nuten an der Halterung eingreifen.The lamp head provided for the holder has a connecting part, by means of which it is mechanically fastened to the holder, and to which contact elements are attached, which likewise interact with the strips of the holder. The connecting part advantageously comprises the bracket in the manner of a clamp and has projections which engage in the grooves on the bracket.

Ein Ausführungsbeispiel der Leuchte nach der Erfindung wird anhand von Zeichnungen näher beschrieben. Es zeigt:

  • Figur 1 die Seitenansicht der Leuchte, teilweise geschnitten
  • Figur 2 eine Draufsicht auf die rohrförmige Aufnahme des Stromversorgungsteils
  • Figur 3 einen Querschnitt der Halterung mit einem daran angeordneten, teilweise dargestellten Leuchtenkopf im Schnitt
An embodiment of the lamp according to the invention is described in more detail with reference to drawings. It shows:
  • Figure 1 shows the side view of the lamp, partially cut
  • Figure 2 is a plan view of the tubular receptacle of the power supply part
  • Figure 3 shows a cross section of the bracket with a partially shown lamp head arranged thereon in section

Die erfindungsgemäße Leuchte besteht aus einem Stromversorgungsteil 1, einer stabförmigen Halterung 2 und drei an der Halterung 2 angeordneten Leuchtenköpfen 3.The lamp according to the invention consists of a power supply part 1, a rod-shaped holder 2 and three lamp heads 3 arranged on the holder 2.

In dem Stromversorgungsteil 1 ist ein Transformator 4 angeordnet, der die vom elektrischen Stromnetz abgegebene Wechselspannung in eine Gleichspannung von wahlweise 12 V, 9 V oder 6 V herunterregelt. In dem Stromversorgungsteil 1 ist wenigstens eine rohrförmige Aufnahme 5 (s. auch Fig. 2) angeordnet, in die die stabförmige Halterung 2 für die Leuchtenköpfe 3 eingesetzt werden kann. Kontaktfedern 6, die die rohrförmige Aufnahme 5 umspannen und mit ihren Enden durch Ausnehmungen in die Aufnahme 5 hineinragen, wirken dann mit den an der Halterung 2 versenkt angeordneten Leisten 8 zusammen. Leitungen 7 verbinden dann die Kontaktfedern 6 mit dem Transformator 4.A transformer 4 is arranged in the power supply part 1 and regulates the alternating voltage emitted by the electrical power network down to a direct voltage of either 12 V, 9 V or 6 V. At least one tubular receptacle 5 (see also FIG. 2) is arranged in the power supply part 1, into which the rod-shaped holder 2 for the lamp heads 3 can be inserted. Contact springs 6, which span the tubular receptacle 5 and protrude with their ends through recesses in the receptacle 5, then interact with the strips 8 which are recessed on the holder 2. Lines 7 then connect the contact springs 6 to the transformer 4.

Die Leisten 8 sind parallel zur Längsachse der Halterung 2 und einander gegenüberliegend an der Halterung 2 angeordnet. Drei Leuchtenköpfe 3 sind daran befestigt. Sie weisen Verbindungsteile 9 auf, die die Halterung 2 klammerartig umfassen. In Höhe der versenkt angeordneten Leisten 8 sind in den Verbindungsteilen 9 federnde Kontaktelemente 10 vorgesehen, die bei einer Auf- und Abbewegung der Leuchtenköpfe 3 an den Leisten 8 entlangschleifen, und mit diesen elektrisch zusammenwirken.The strips 8 are arranged parallel to the longitudinal axis of the holder 2 and opposite one another on the holder 2. Three lamp heads 3 are attached to it. They have connecting parts 9, which enclose the holder 2 like a clamp. At the level of the recessed strips 8, resilient contact elements 10 are provided in the connecting parts 9, which grind along the strips 8 when the lamp heads 3 move up and down, and interact electrically with them.

Dadurch, daß die Leisten 8 einander gegenüberliegend an der Halterung 2 angeordnet sind, ist es möglich, die Leuchtenköpfe 3 auch um 1800 verdreht auf die Halterung 2 aufzusetzen. Dies erweitert die Einsatzmöglichkeit der Leuchte.Characterized in that the strips 8 are arranged opposite each other on the holder 2, it is possible to use the lighting heads 3 and 0 180 twist set up on the holder. 2 This extends the possible uses of the lamp.

Es ist auch möglich, weitere Aufnahmen 5 für die Halterung in dem Stromversorgungsteil 1 der Leuchte vorzusehen, so daß die Halterung 2 beispielsweise auch in eine andere Lage zum Stromversorgungsteil 1 gebracht werden kann.It is also possible to take additional shots 5 for the stops tion to be provided in the power supply part 1 of the lamp, so that the holder 2 can, for example, be brought to the power supply part 1 in a different position.

In dem beschriebenen Ausführungsbeispiel sind die Leuchtenköpfe 3 gegenüber den Verbindungsteilen 9 zu der Halterung 2 dreh- und schwenkbar ohne Verwendung von zusätzlichen Kabeln angeordnet. Dies wird durch ein Kugelgelenk erreicht, das sowohl die mechanische als auch die elektrische Verbindung zwischen beiden Teilen herstellt.In the exemplary embodiment described, the lamp heads 3 are arranged such that they can be rotated and pivoted relative to the connecting parts 9 to the holder 2 without the use of additional cables. This is achieved by means of a ball joint that creates both the mechanical and the electrical connection between the two parts.
