Description

Die Erfindung bezieht sich auf eine Strahler-Leuchte nach dem Oberbegriff des Anspruches 1.The invention relates to a spotlight lamp according to the preamble of Claim 1.

Eine Strahler-Leuchte dieser Art ist allgemein bekannt. Es ist ein wesentliches Merkmal einer Strahler-Leuchte, daß sie ein Strahlergehäuse mit einer Lichtquelle aufweist, das zum Zweck der Beleuchtung wahlweiser Stellen des die Strahler-Leuchte enthaltenden Raumes schwenkbar mit einem Betriebsgerät verbunden ist, das durch einen Trägerarm an das Stromschienen-System anbringbar ist. Bei bekannten Strahler-Leuchten ist das Strahlergehäuse am freien Ende eines am Betriebsgerät abgestützten Schwenkarmes angeordnet. Das Strahlergehäuse ist somit relativ zum Betriebsgerät zwecks Beleuchtung einer im Verstellbereich des Schwenkarmes wahlweisen Stelle schwenkbar und in der eingestellten Schwenkposition feststellbar. Hierbei kommt es insbesondere dann, wenn der Schwenkarm sich quer zur Schwerkraftrichtung, also z. B. horizontal, erstreckt zu beträchtlichen Belastungen des Betriebsgerätes, die durch den horizontalen Abstand des Strahlergehäuses vom Betriebsgerät und des Gewichts des Strahlergehäuses bedingt sind.A spotlight lamp of this type is generally known. It is an essential feature a spotlight lamp that it has a spotlight housing with a light source, the for the purpose of illuminating optional locations of the spotlight luminaire Room is pivotally connected to an operating device by a support arm can be attached to the busbar system. This is the case with known spotlights Spotlight housing at the free end of a swivel arm supported on the control gear arranged. The lamp housing is therefore relative to the control gear Illumination of an optional position in the adjustment range of the swivel arm can be swiveled and lockable in the set swivel position. This is particularly important then when the swivel arm is transverse to the direction of gravity, ie z. B. horizontal, extends to considerable loads on the control gear caused by the horizontal Distance of the spotlight housing from the control gear and the weight of the spotlight housing are conditional.

Vergleichbare Belastungen werden im an das Stromschienen-System anmontierten Zustand der Strahler-Leuchte auch in das Stromschienen-System eingeleitet, in dem die Belastungen nicht nur zu Spannungen führen, sondern auch die verschiebbare Lagerung in der Schienenführung beeinträchtigen. Die Belastungen erfordern somit nicht nur eine stabile und entsprechend aufwendige Bauweise für das Betriebsgerät, den Trägerarm und das Stromschienen-System, sondern sie beeinträchtigen auch die Schienenführung, wodurch nicht nur hohe Antriebskräfte zum Verschieben im Stromschienen-System erforderlich sind, sondern auch die Lebensdauer herabgesetzt wird.Comparable loads are installed in the track system Condition of the spotlight lamp also introduced into the busbar system in which the Loads not only lead to tension, but also the sliding bearing in the rail guide. The loads therefore do not only require one stable and correspondingly complex design for the control gear, the support arm and the busbar system, but they also affect the rail routing, which means not only high driving forces for moving in the busbar system are required, but also the service life is reduced.

Die Erfindung liegt die Aufgabe zugrunde, bei einer Strahler-Leuchte der eingangs angegebenen Art die Belastungen zu verringern.The invention is based, with a spotlight lamp the task specified type to reduce the loads.

Diese Aufgabe wird durch die Merkmale des Anspruches 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen beschrieben. This object is solved by the features of claim 1. Beneficial Developments of the invention are described in the subclaims.

Bei der erfindungsgemäßen Strahler-Leuchte ist die Verbindungsstelle zwischen dem Trägerarm und dem Betriebsgerät an dem Betriebsgerät verstellbar. Hierdurch ist es möglich, die Verbindungsstelle so zu verlagern, daß ihr Abstand zum Strahlergehäuse möglichst gering ist und somit auch die sich ergebende Hebelarmlänge mit der das Strahlergehäuse seine Belastungen in das Betriebsgerät und in das Stromschienen-System einleitet, verringert ist. Folglich lassen sich somit die auf das Betriebsgerät und auf das Stromschienen-System wirksamen Belastungen wesentlich verringern.In the spotlight lamp according to the invention, the connection point between the Carrier arm and the control gear adjustable on the control gear. This is it possible to shift the connection point so that its distance from the spotlight housing is as small as possible and thus the resulting lever arm length with the Spotlight housing its loads in the control gear and in the busbar system initiates, is reduced. Consequently, the control gear and reduce the effective loads on the busbar system significantly.

Die Verstellbewegungsrichtung der Verbindungsstelle verläuft vorzugsweise im wesentlichen horizontal. Hierbei kann die Reibung zwischen den Verbindungsteilen ein Positioniermittel bilden, das eine unbeabsichtigte Verstellung verhindert. Insbesondere dann, wenn die Verstellrichtung nicht horizontal verläuft, ist es zwecks Positionierung vorteilhaft, ein Positioniermittel anzuordnen.The direction of movement of the connection point is preferably in essentially horizontal. Here, the friction between the connecting parts Form a positioning device that prevents unintentional adjustment. In particular if the direction of adjustment is not horizontal, it is for positioning advantageous to arrange a positioning means.

Der durch die Erfindung erzielbare Vorteil läßt sich immer dann erreichen, wenn durch eine Verstellung der Verbindungsstelle die unter Berücksichtigung der Schwerkraft wirksame Hebelarmlänge des Strahlergehäuses von der Verbindungsstelle verringert werden kann. Dies ist nicht nur dann möglich, wenn die Bewegungsrichtung des Strahlergehäuses parallel zum Verstellweg der Verbindungsstelle gerichtet ist, sondern auch dann, wenn die Verstellrichtung des Strahlergehäuses quer zur Verstellbewegungsrichtung der Verbindungsstelle gerichtet ist. Folglich ergeben sich sowohl bei einem quer zur Bewegungsrichtung der Verbindungsstelle verstellbaren Verstellarm als auch bei einem horizontal allseitig verstellbaren oder räumlich allseitig verstellbaren Verstellarm Teilbereiche des jeweils vorhandenen Freiheitsgrades, in denen die wirksame Hebelarmlänge durch eine Verstellung der Verbindungsstelle verringerbar ist. Eine besonders deutliche Wirksamkeit der erfindungsgemäßen Ausgestaltung ergibt sich dann, wenn die Verstellrichtung des Verstellarmes parallel zur Verstellbewegungsrichtung der Verschiebestelle gerichtet ist oder in einer parallelen Ebene schwenkbar ist.The advantage achievable by the invention can always be achieved if by an adjustment of the connection point taking into account gravity effective lever arm length of the spotlight housing is reduced from the connection point can be. This is not only possible if the direction of movement of the Spotlight housing is directed parallel to the adjustment path of the connection point, but even if the direction of adjustment of the lamp housing is transverse to Direction of movement of the connection point is directed. Hence arise both with an adjustable transverse to the direction of movement of the connection point Adjustable arm as well as with a horizontally adjustable on all sides or spatially on all sides adjustable arm partial areas of the existing degree of freedom, in which the effective lever arm length by adjusting the connection point can be reduced. A particularly clear effectiveness of the invention Design results when the adjustment direction of the adjustment arm is parallel to Direction of movement of the displacement point is directed or in a parallel Level is pivotable.

Für eine erfindungsgemäße Verstellung eignet sich eine Schiebeführung sehr vorteilhaft, wobei diese in das Betriebsgerät, z. B. in ein Gehäuse des Betriebsgerätes, integriert sein kann oder am Betriebsgerät bzw. dessen Gehäuses angebaut sein kann. Eine einfache und funktionsfähige sowie kostengünstig herstellbare Schiebeführung läßt sich durch ein Langloch in einer Gehäusewand eines Gehäuses des Betriebsgerätes erreichen. Eine vorteilhafte Anordnungsstelle der Verbindungsstelle ist dann gegeben, wenn sie sich an der dem Stromschienen-System zugewandten Seite des Betriebsgerätes bzw. dessen Gehäuses befindet. Bei einem Stromschienen-System für eine Raumdecke ist es vorteilhaft, die Verbindungsstelle an der Oberseite bzw. an oder in der Deckenwand des Gehäuses auszubilden.A sliding guide is very advantageous for an adjustment according to the invention, these in the operating device, for. B. integrated into a housing of the operating device can be or can be attached to the control gear or its housing. A simple and functional and inexpensive to produce sliding guide can reach through an elongated hole in a housing wall of a housing of the operating device. An advantageous location of the connection point is given if it on the side of the control gear facing the busbar system or whose housing is located. It is with a track system for a ceiling advantageous, the connection point on the top or on or in the ceiling wall of the Training housing.

Insbesondere dann, wenn die Schiebeführung durch ein Langloch gebildet ist, ist es vorteilhaft, eine Abdeckung für das Langloch vorzusehen, die eine Verschmutzung durch das Langloch hindurch verhindert. Hierzu eignet sich aus Gründen der Material-und Gewichtsersparnis ein dünnes Abdeckelement, z. B. ein Blech oder eine Folie. Je nach der Größe des Betriebsgerätes und nach der Länge der Verstellbewegung der Verbindungsstelle ist es vorteilhaft, ein elastisch biegsames Abdeckelementes zu verwenden. Ein solches Abdeckelementes ermöglicht es, ein Langloch und somit den Verstellweg der Verbindungsstelle möglichst lang auszubilden. Aufgrund der Biegsamkeit des Abdeckelementes kann dieses bei einer Verstellung in die Endbereich des Langloches abgebogen werden, ohne über das Betriebsgerät hinaus vorzustehen oder bei einer Anordnung in einem Betriebsmittelgehäuse gegen eine zugehörige Seitenwand des Betriebsmittelgehäuses zu stoßen.In particular, if the sliding guide is formed by an elongated hole, it is advantageous to provide a cover for the slot, which is a pollution prevented through the slot. This is suitable for reasons of material and Weight saving a thin cover, z. B. a sheet or a film. Each according to the size of the control gear and the length of the adjustment movement Connection point, it is advantageous to an elastically flexible cover element use. Such a cover element enables an elongated hole and thus the Design the adjustment path of the connection point as long as possible. Due to the The cover element can be flexible when it is adjusted in the end region of the elongated hole can be bent without protruding beyond the control gear or with an arrangement in an equipment housing against an associated one To bump the side wall of the equipment housing.

Die erfindungsgemäße Ausgestaltung ermöglicht somit eine einfache und vorteilhafte Verstellung der Verbindungsstelle. Eine dies ermöglichende Verstellvorrichtung läßt sich einfach und kostengünstig realisieren.The configuration according to the invention thus enables simple and advantageous Adjustment of the connection point. An adjustment device that enables this can be realized easily and inexpensively.

Es ist vorteilhaft, das Abdeckelement 42 aus einem dünnen Laminat aus elastisch biegbarem Material zu fertigen, z. B. federndem Metall, insbesondere Federstahl, oder Kunststoff. Nach einer Ausbiegung bedarf es aufgrund der Eigenelastizität keiner aktiven Rückbiegung des Abdeckelementes 42, da es sich selbsttätig in seine sich gerade bzw. eben erstreckende Ausgangsstellung zurückbiegt. Bei dem Abdeckelement 42 kann es sich z. B. um eine Folie mit einer Dicke d von etwa 0,3 mm handeln.The length L of the cover element 42 is dimensioned so large that when that Connecting element 4a is in one end position in the elongated hole 35, the Cover element 42 extends to the other end of the elongated hole 35 and the The slot opening thus closes. In cases where the slotted ends opposite walls of the equipment housing 16 such a large distance have that the ends of the cover member 42 between the ends of the elongated hole 35th and the side walls have enough space, the ends of the Cover element 42 are pushed into these free spaces. If however, the distances between the elongated hole ends and the side walls are smaller and / or this free space for the cover element ends behind the elongated hole ends should stop, it is possible to move the connection point to the relevant one The cover element 42 is slotted towards the inside by means of a deflection device 43 of the equipment housing 16 to bend into it. For this purpose, the cover element 42 pliable, preferably pliable against an elastic restoring force, which in particular is formed by inherent elasticity. Such a deflection device 43 can by a Curved path or curved elements arranged one behind the other in a curve. It is advantageous to cover element 42 from a thin laminate of elastic to produce bendable material, e.g. B. resilient metal, especially spring steel, or Plastic. After a bend no one is required due to the inherent elasticity active bending back of the cover element 42, since it is automatically in its straight or just extends the starting position. In the cover 42 can z. B. is a film with a thickness d of about 0.3 mm.
