Abstract

Lamp, in particular a halogen lamp, having a cap 1 containing a power pack (power supply unit), and a lamp head 7 containing the luminous element, as well as an electrically conducting flat spiral spring (trip, coil, tripping spring) connection between the cap and lamp head. Said connection can be adjusted by means of an adjusting device 16 having a cable 10. The electrically conducting flat spiral spring connection is formed between the cap and the lamp head by two flat spiral springs 4 which are pivotably mounted in a symmetrical fashion on mutually opposite sides of the cap and the lamp head. Provided on the lamp head are latches 8 on which the cable acts and via which it is simultaneously possible to set the pivoted position of the lamp head. The cable forms a continuously settable cable pull which can preferably be fixed in a force-closed fashion at a predetermined length. <IMAGE>

Bei einer aus der DE-OS 35 06 737 bekannten Lampe ist ein Lampenkopf an einem elektrisch leitenden Federstahlband und eine Verstelleinrichtung mit einem Seilzug vorgesehen. Der Nachteil dieser Konstruktion besteht darin, daß eine mechanische Aufrolleinrichtung mit Feststellautomatik für das Seil erforderlich 7o ist. Die Erfindung zielt darauf ab, eine Lampe der einleitend angegebenen Art zu schaffen, deren Konstruktion eine einfache Abstützung des Lampenkopfes gegenüber dem Stockei und zugleich eine einfache Verstellung des Lampenkopfes hinsichtlich seiner Höhe über dem Sockel und seiner Neigung bzw. Schwenklage gegenüber dem Sockel aufweist. Die erfindungsgemäße Lampe zeichnet sich dadurch aus, 15 daß die elektrisch leitende Bandfederverbindung zwischen dem Sockel und dem Lampenkopf durch zwei Bandfedern gebildet ist, die auf einander gegenüberliegenden Seiten des Sockels und des Lampenkopfes symmetrisch schwenkbeweglich gelagert sind, und daß am Lampenkopf Rasten vorgesehen sind, an denen das Seil der Verstelleinrichtung angreift und über welche zugleich die Schwenkiage des Lampenkopfes einstellbar ist, wobei in an sich bekannter Weise das Seil der Verstelleinrichtung 20 Ein Ausführungsbeispiel der Erfindung wird nachfolgend unter Bezugnahme auf die Zeichnung näher beschrieben, in der Fig. 1 eine Schrägansicht der Lampe gemäß der Erfindung zeigt und die Fig. 2a bis 2c schematisch verschiedene Lampenstellungen. Die erfindungsgemäße Lampe besteht aus einem Sockel 1, in welchem ein Netzgerät untergebracht ist. Zwei Seitenteile 2 des Sockels 1 sind durch Rohre 3 verbunden, in die beidseits des Sockels 1 zwei 25 Bandstahlfedern 4 eingesteckt sind, die an ihrem freien Ende an zwei parallelen Hülsen 5 angreifen, die in einem Schwenkteil 6 gelagert sind und an ihrem anderen Ende den Lampenkopf 7 tragen. Zur Höhenverstellung des Lampenkopfes 7 bzw. zur Veränderung der Schräglage desselben sind in dem Schwenkteil 6 Rasten 8 ausgebildet, in die ein Haken 9 an einem Ende eines Seilzuges 10 eingehängt ist, der durch zwei Ösen 11 im Sockel 1 sowie durch Löcher 12, 13, 14 einer dreieckigen Führung 15 30 geführt ist, die es ermöglicht, die Länge des Seilzuges 10 zu verstellen, und damit die Höhenlage des Lampenkopfes 7 gegenüber dem Sockel 1 zu verändern sowie eine Verstelleinrichtung 16 zu bilden. Je nachdem, welche der Rasten 8 verwendet wird, wird dabei die Schwenklage des Lampenkopfes 7 gegenüber dem Sockel 1 verändert. Fig. 2a zeigt die höchste Lage des Lampenkopfes 7, wenn die Führung 15 in der untersten Stellung ist, 35 Fig. 2b zeigt eine mittlere Lage des Lampenkopfes 7, wenn die Führung 15 in einer mittleren Stellung ist, und Fig. 2c zeigt die niedrigste Lage des Lampenkopfes 7 in verschwenktem Zustand, wenn die Führung 15 in der höchsten Stellung ist. Patentansprüche 40 1. Lampe, insbesondere Halogenlampe, mit einem ein Netzgerät enthaltenden Sockel und einem das Leuchtelement enthaltenden Lampenkopf sowie einer elektrisch leitenden Bandfederverbindung zwischen Sockel und Lampenkopf, die mittels einer ein Seil aufweisenden Verstelleinrichtung verstellbar ist, dadurch gekennzeichnet, daß die elektrisch leitende Bandfederverbindung zwischen dem Sockel 45 (1) und dem Lampenkopf (7) durch zwei Bandfedern (4) gebildet ist, die auf einander gegenüberliegen den Seiten des Sockels und des Lampenkopfes symmetrisch schwenkbeweglich gelagert sind, und daß am Lampenkopf (7) Rasten (8) vorgesehen sind, an denen das Seil (10) der Verstelleinrichtung (16) angreift und über welche zugleich die Schwenklage des Lampenkopfes (7) einstellbar ist, wobei in an sich bekanntes Weise das Seil (10) der Verstelleinrichtung (16) einen stufenlos einstellbaren Seilzug so bildet, der vorzugsweise kraftschlüssig in einer vorbestimmten Länge feststellbar ist. HiezuAT 398 820 B The invention relates to a lamp, in particular a halogen lamp, with a base containing a power supply unit and a lamp head containing the lighting element, and an electrically conductive band spring connection between the base and the lamp head, which is adjustable by means of an adjusting device having a rope. 5 So far, numerous mechanical lever and joint connections are known for the mechanical connection of base and lamp head or for adjusting the same, which are relatively complex. In a lamp known from DE-OS 35 06 737, a lamp head is provided on an electrically conductive spring steel strip and an adjustment device with a cable pull. The disadvantage of this construction is that a mechanical retractor with automatic locking is necessary for the rope. The invention aims to provide a lamp of the type mentioned in the introduction, the construction of which has a simple support of the lamp head relative to the stock egg and at the same time a simple adjustment of the lamp head with regard to its height above the base and its inclination or pivoting position relative to the base. The lamp according to the invention is characterized in that the electrically conductive band spring connection between the base and the lamp head is formed by two band springs which are mounted on opposite sides of the base and the lamp head in a symmetrically pivotable manner, and that notches are provided on the lamp head which the rope of the adjusting device engages and via which the swiveling of the lamp head can be adjusted at the same time, the rope of the adjusting device 20 in a manner known per se. An embodiment of the invention is described in more detail below with reference to the drawing, in FIG. 1 an oblique view of the Lamp according to the invention shows and FIGS. 2a to 2c schematically different lamp positions. The lamp according to the invention consists of a base 1, in which a power supply unit is accommodated. Two side parts 2 of the base 1 are connected by pipes 3, in the two sides of the base 1 two 25 steel coil springs 4 are inserted, which engage at their free end on two parallel sleeves 5, which are mounted in a pivot part 6 and at the other end Wear lamp head 7. To adjust the height of the lamp head 7 or to change the inclined position thereof, notches 8 are formed in the swivel part 6, into which a hook 9 is suspended at one end of a cable pull 10, which is connected by two eyelets 11 in the base 1 and by holes 12, 13, 14 a triangular guide 15 30 is guided, which makes it possible to adjust the length of the cable 10, and thus to change the height of the lamp head 7 relative to the base 1 and to form an adjusting device 16. Depending on which of the detents 8 is used, the pivoting position of the lamp head 7 relative to the base 1 is changed. 2a shows the highest position of the lamp head 7 when the guide 15 is in the lowest position, 35 FIG. 2b shows a middle position of the lamp head 7 when the guide 15 is in a middle position, and FIG. 2c shows the lowest Position of the lamp head 7 in the pivoted state when the guide 15 is in the highest position. 40. Lamp, in particular halogen lamp, with a base containing a power supply and a lamp head containing the lighting element and an electrically conductive band spring connection between the base and the lamp head, which is adjustable by means of an adjusting device having a rope, characterized in that the electrically conductive band spring connection between the base 45 (1) and the lamp head (7) is formed by two ribbon springs (4) which are mounted on the sides of the base and the lamp head symmetrically pivotably on opposite sides, and that notches (8) are provided on the lamp head (7) , on which the cable (10) of the adjusting device (16) acts and via which the pivot position of the lamp head (7) can be adjusted, the cable (10) of the adjusting device (16) forming a continuously adjustable cable pull in a manner known per se , which is preferably non-positively ascertainable in a predetermined length is.
