Description

Die Erfindung betrifft einen Strahler mit einem Trägerteil, das an einem Ende eine mechanisch-elektrische Anschlußein­heit aufweist und am anderen Ende über ein Schwenkgelenk mit einem Leuchtenteil verbunden ist.The invention relates to a spotlight with a support part which has a mechanical-electrical connection unit at one end and is connected to a lamp part at the other end via a swivel joint.

Strahler sind in unterschiedlichster Ausgestaltung und für verschiedenartigste Leuchtmittel sowohl im gewerblichen als auch im privaten Bereich in großer Anzahl im praktischen Ein­satz. Üblicherweise sind die jeweiligen Strahlerkonstruktio­nen sowohl in technischer als auch gestalterischer Hinsicht an das jeweils verwendete Leuchtmittel angepaßt und nur für bestimmte Leuchtmittel geeignet. In vielen Fällen ist dabei störend, daß die Strahler vergleichsweise voluminös sind und hinsichtlich der Anpassbarkeit an die verschiedenen Beleuch­tungsaufgaben in ihrer Variabilität stark zu wünschen übrig lassen.Spotlights are in a wide variety of designs and for a wide variety of lamps both in commercial and private use in large numbers in practical use. Usually, the respective spotlight constructions are adapted both technically and creatively to the illuminant used in each case and are only suitable for certain illuminants. In many cases it is disturbing that the spotlights are comparatively voluminous and leave much to be desired in terms of their variability in terms of adaptability to the various lighting tasks.

Aufgabe der Erfindung ist es, einen Strahler der eingangs an­gegebenen Art so auszubilden, daß unter Beibehaltung einer einheitlichen, grazilen Grundstruktur einerseits die Verwen­dung unterschiedlichster Leuchtmittel ermöglicht und anderer­seits hinsichtlich der sich in der Praxis stellenden Beleuch­tungsaufgaben größtmögliche Variabilität erreicht wird.The object of the invention is to design a spotlight of the type mentioned in such a way that, while maintaining a uniform, graceful basic structure, on the one hand enables the use of a wide variety of illuminants and on the other hand the greatest possible variability is achieved with regard to the lighting tasks encountered in practice.

Gelöst wird diese Aufgabe nach der Erfindung im wesentlichen dadurch, daß das Trägerteil im wesentlichen stabförmig ausge­bildet und zumindest auf einem Teil seiner Länge in ein mit dem festen Element des Schwenkgelenks verbundenes Basisteil und ein mit dem beweglichen Element des Schwenkgelenks ver­bundenes, zumindest den Leuchtenteil tragendes Schwenkteil unterteilt ist und das Schwenkgelenk bezüglich der Stabachse außermittig angeordnet ist.This object is essentially achieved according to the invention characterized in that the support part is essentially rod-shaped and is divided at least over part of its length into a base part connected to the fixed element of the swivel joint and a swivel part connected to the movable element of the swivel joint and carrying at least the lamp part, and the swivel joint is eccentric with respect to the rod axis is arranged.

Die stabförmige Grundstruktur und die Auftrennung dieser Grundstruktur in ein Basisteil und ein Schwenkteil über eineschrägverlaufende Trennebene erbringt über die außermit­tig gelegene Schwenkachse eine hohe Variabilität in den Richtmöglichkeiten des Leuchtmittels einerseits und in der Verwendbarkeit unterschiedlicher Leuchtmittel andererseits, da das ebenfalls stabförmige Grundform besitzende Schwenk­teil an seinem freien Ende zur Aufnahme aller Arten von Leuchtmittel ohne jegliche Veränderung der Grundstruktur aus­gebildet sein kann.
Zu der optischen und ästhetischen Ausgewogenheit der Grund­struktur kommt hinzu, daß das jeweilige Leuchtmittel und das Basisteil gewichtsmäßig ausgewogen gestaltet werden können, so daß über das entsprechend auszubildende Schwenkgelenk eine unkomplizierte und austarierte Neigungsverstellung des jeweiligen Leuchtmittels erfolgen kann.The rod-shaped basic structure and the division of this basic structure into a base part and a pivoting part via a sloping parting plane provides a high variability in the directional possibilities of the illuminant on the one hand and in the usability of different illuminants on the other hand, because the pivoting part, which also has a rod-shaped basic shape, has at its free End for receiving all types of lamps can be formed without any change in the basic structure.
In addition to the optical and aesthetic balance of the basic structure, there is also the fact that the respective illuminant and the base part can be designed to be balanced in terms of weight, so that an uncomplicated and balanced inclination adjustment of the respective illuminant can take place via the swivel joint to be designed accordingly.

Durch die Wahl des Verlaufs der Trennebene zwischen Basis­teil und Schwenkteil läßt sich auch eine sowohl in techni­scher Hinsicht günstige gewichtsmäßige Ausgewogenheit als auch in ästhetischer Hinsicht optimale Verteilung zwischen Leuchtmittelbereich und Schwenkteil erzielen.The choice of the course of the parting plane between the base part and the swivel part can also achieve a balance in terms of weight that is favorable from a technical point of view as well as an optimal distribution between the illuminant area and the swivel part from an aesthetic point of view.

Nach einer vorteilhaften Ausgestaltung der Erfindung wird das Schwenkteil gleichzeitig als Trägerteil für elektrische Funktionselemente, wie z. B. ein Schaltnetzteil oder ein Zündgerät verwendet, wobei durch Ausnutzung des in diesem Be­ reich zur Verfügung stehenden Freiraums eine Formgestaltung für diese elektrischen Funktionselemente gewählt werden kann, die der grazilen Stabstruktur angepaßt ist und sich auf die gewichtsmäßige Austarierung des gesamten Schwenk­teils bezogen auf die Schwenkachse günstig auswirkt.According to an advantageous embodiment of the invention, the pivot part is simultaneously used as a support part for electrical functional elements, such as. B. uses a switching power supply or an ignitor, by exploiting the Be in this abundant available space, a design for these electrical functional elements can be selected, which is adapted to the delicate rod structure and has a favorable effect on the weight-based balancing of the entire swivel part in relation to the swivel axis.

Zwischen dem Basisteil und dem Schwenkteil wird nach einer weiteren Ausgestaltung der Erfindung eine steuerbare Verstel­lung vorgesehen, so daß auf einfache Weise auch eine Fern­steuerung der Abstrahlrichtung des Strahlers realisiert werden kann. Die Verstellvorrichtung kann beispielsweise aus einem Memory-Metall bestehen oder über einen Kleinmotor rea­lisiert werden, der in der Stabstruktur untergebracht ist. Günstig ist bei all diesen möglichen Verstellvorrichtungen, daß zum Zwecke der Verstellung nur sehr geringe Kräfte not­wendig sind, da bezogen auf das Schwenkgelenk konstruktions­bedingt ein weitestgehender Gewichtsausgleich realisierbar ist.According to a further embodiment of the invention, a controllable adjustment is provided between the base part and the swivel part, so that remote control of the radiation direction of the radiator can also be implemented in a simple manner. The adjustment device can consist, for example, of a memory metal or can be implemented using a small motor which is accommodated in the rod structure. It is favorable with all these possible adjustment devices that only very small forces are necessary for the purpose of the adjustment, since a weight compensation as far as possible can be achieved based on the design of the swivel joint.

Über die Stabstruktur und ggf. in dieser Struktur vorgesehe­ne, insbesondere zwischen Leuchtmittel und Schwenkgelenk ge­legene Querschnittsverringerungen kann auch eine optimale thermische Entkopplung erreicht werden.Optimal thermal decoupling can also be achieved via the rod structure and any cross-sectional reductions provided in this structure, in particular between the illuminant and the swivel joint.

Die gemäß der Erfindung ausgebildeten Strahler sind sowohl mit standardisierten Lichtschienen über entsprechende Adap­ter als auch mit anderen Arten von Schienen über entsprechen­de Anpaßeinheiten verwendbar und ferner natürlich auch zur Direktmontage geeignet. Verwendbar sind als Leuchtmittel sowohl Niedervoltstrahler als auch direkt gespeist Strahler sowie praktisch alle speziellen im Handel befindlichen weite­ren Leuchten.The spotlights designed in accordance with the invention can be used both with standardized light rails via appropriate adapters and with other types of rails via corresponding adapter units and, of course, are also suitable for direct mounting. Both low-voltage spotlights and direct-fed spotlights as well as practically all special other lights on the market can be used as illuminants.

Fig. 1 zeigt eine herkömmliche Lichtschiene 14, an der über einen Adapter 10 das Trägerteil 1 eines Strahlers nach der Erfindung befestigt bzw. mechanisch und elektrisch gekoppelt ist. Das stabförmig ausgebildete Trägerteil 1 ist in zwei über ein Schwenkgelenk 3 miteinander verbundene Teile unter­teilt, nämlich in ein festes Basisteil 4 und ein Schwenkteil 5, das gleichzeitig Träger des Leuchtenteils 2 bzw. des je­weils verwendeten Leuchtmittels ist.1 shows a conventional light rail 14 to which the carrier part 1 of a spotlight according to the invention is fastened or mechanically and electrically coupled via an adapter 10. The rod-shaped support part 1 is subdivided into two parts which are connected to one another via a swivel joint 3, namely into a fixed base part 4 and a swivel part 5, which is at the same time the support of the lighting part 2 or of the respectively used illuminant.

Das Schwenkgelenk 3 ist bezüglich der Stabachse 6 außermit­ tig gelegen und die Achse dieses Schwenkgelenks 3 verläuft senkrecht zur Stabachse 6. Mit dem festen Teil 7 des Schwenk­gelenks 3 ist das Basisteil 4, mit dem beweglichen Teil 8 ist das Schwenkteil 5 der Stabstruktur verbunden. Die Trenne­bene 9 zwischen dem Basisteil 4 und dem Schwenkteil 5 ver­läuft unter einem spitzen Winkel zur Stabachse 6, und im Be­reich dieser Trennebene 9 ist ein über die Umfangskontur der Trennebene überstehendes Verbreiterungs- und/oder Verlänge­rungselement 11 vorgesehen.The swivel joint 3 is outside of the rod axis 6 tig located and the axis of this swivel joint 3 is perpendicular to the rod axis 6. With the fixed part 7 of the swivel joint 3 is the base part 4, with the movable part 8, the swivel part 5 of the rod structure is connected. The parting plane 9 between the base part 4 and the swivel part 5 runs at an acute angle to the rod axis 6, and in the region of this parting plane 9 a widening and / or extension element 11 projecting beyond the circumferential contour of the parting plane is provided.

Die Achse des Schwenkgelenks 3 liegt bei dieser Ausführungs­variante etwa im Bereich einer Mantellinie des Trägerteils 1.In this embodiment variant, the axis of the swivel joint 3 lies approximately in the region of a surface line of the carrier part 1.

Die Trennebene 9 wird vorzugsweise so gelegt, daß das Schwenkteil 5 einen Gewichtsausgleich für den Leuchtenteil 2 bildet, so daß ein Verschwenken des Leuchtenteils 2 umd die Schwenkachse 3 mit sehr geringer Kraft möglich ist und eine leichte Schwergängigkeit des Gelenks 3 eine sichere Fixie­rung des Leuchtenteils in einer beliebigen Schwenklage inner­halb des gegebenen Schwenkbereichs gewährleistet.The parting plane 9 is preferably placed in such a way that the swivel part 5 forms a weight balance for the light part 2, so that pivoting of the light part 2 and the swivel axis 3 is possible with very little force and a slight stiffness of the joint 3 ensures secure fixation of the light part in guaranteed any swivel position within the given swivel range.

Die Ausführungsform nach Fig. 2 verdeutlicht, daß bei glei­cher Grundstruktur nicht nur ohne Schwierigkeiten andere Leuchtmittel verwendbar sind, sondern daß auch die Trennebe­ne 9 unterschiedlich gestaltbar ist und sich nahezu über die gesamte Länge des Trägerteils 1 erstrecken kann. Zweckmäßi­gerweise verläuft die Trennebene 9 über einen größeren Be­reich entsprechend der Stabachse 6, so daß kurze Schrägabsch­nitte der Trennebene, die vorzugsweise bezüglich der Stabach­se 6 unter dem gleichen Winkel verlaufen, die Gesamt-Trenne­bene vervollständigen können. In dieser Fig. 2 verdeutlicht die um 90° verschwenkte Position den erreichbaren Gewichts­ausgleich zwischen Leuchtmittel 2 und dem in dieser Position das Gegengewicht bildenden Schwenkteil 5′ mit zugehörigem Verbreiterungselement 11′.The embodiment according to FIG. 2 illustrates that, with the same basic structure, not only can other illuminants be used without difficulty, but also that the parting plane 9 can be designed differently and can extend almost over the entire length of the carrier part 1. The parting plane 9 expediently extends over a larger area corresponding to the rod axis 6, so that short inclined sections of the parting plane, which preferably run at the same angle with respect to the rod axis 6, can complete the overall parting plane. In this Fig. 2, the position pivoted by 90 ° illustrates the achievable weight balance between the illuminant 2 and the counterweight in this position forming the pivoting part 5 'with the associated widening element 11'.

Über eine Querschnittsverringerung 18 zwischen Schwenkteil 5 und Leuchtmittel 2 läßt sich eine erwünschte thermische Ent­kopplung realisieren.A desired thermal decoupling can be achieved by reducing the cross section 18 between the pivoting part 5 and the illuminant 2.

Die Ausführungsvariante nach Fig. 3 verdeutlicht, daß selbst bei Verwendung einer vergleichsweise kurzen Trennebene 9 durch Verwendung eines Verlängerungselements in Stab- bzw. Flachstabform das sowohl unter technischen als auch unter ästhetischen Gesichtspunkten wichtige Gegengewicht zum jewei­ligen Leuchtmittel 2 geschaffen werden kann, ohne die grazi­le Grundstruktur des Strahlers zu verlassen.3 illustrates that even when using a comparatively short parting plane 9 by using an extension element in the form of a rod or flat bar, the counterweight to the respective illuminant 2, which is important both from a technical and an aesthetic point of view, can be created without the delicate basic structure to leave the spotlight.

Fig. 4 zeigt eine Ausführungsform der Erfindung, bei der die Stabstruktur des Trägerteils 1 durch ein angeformtes oder kuppelbares Zusatzteil mit einem Knickbereich 15 versehen werden kann, so daß sich bezogen auf eine Befestigungsstelle bzw. Stromschiene eine unter einem vorgebbaren Winkel verl­aufende Schrägstruktur des Strahlers ergibt, die für bestimm­te Beleuchtungsaufgaben aufgrund des dadurch erzielbaren Schwenkwinkels von besonderem Vorteil ist.Fig. 4 shows an embodiment of the invention, in which the rod structure of the support part 1 can be provided with a kink region 15 by means of an integrally formed or connectable additional part, so that there is an oblique structure of the radiator running at a predeterminable angle with respect to a fastening point or busbar , which is particularly advantageous for certain lighting tasks due to the pivoting angle that can be achieved thereby.

Fig. 5 zeigt eine Ausführungsvariante, die die Variabilität hinsichtlich des Einsatzes unterschiedlicher Leuchtmittel de­monstriert und gleichzeitig erkennen läßt, daß das Schwenk­teil 5 für bestimmte Ausführungsformen besonders günstig als Träger für elektrische Funktionsteile verwendbar ist.FIG. 5 shows an embodiment variant which demonstrates the variability with regard to the use of different illuminants and at the same time shows that the pivoting part 5 can be used particularly advantageously as a carrier for electrical functional parts for certain embodiments.

Im dargestellten Beispiel wird als Leuchtmittel eine energie­sparende Leuchte verwendet, die die Verwendung eines Schalt­netzteiles 12 erfordert. Dieses Schaltnetzteil kann in Form eines flachen Quaders ausgebildet sein und vorzugsweise über Steckkupplungen mit dem Schwenkteil 5 mechanisch und elek­trisch verbunden werden.
Die Ausführungsvariante nach Fig. 5 verdeutlicht auch, daß hinsichtlich der Positionierung des Schwenkgelenks im Rahmen der Erfindung eine Variabilität besteht, welche eine Anpas­sung an die jeweils vorliegenden Gegebenheiten gestattet, aber die Grundstruktur des Strahlers nicht grundlegend verän­dert.In the example shown, an energy-saving lamp is used as the illuminant, which requires the use of a switching power supply 12. This switching power supply can be designed in the form of a flat cuboid and can preferably be mechanically and electrically connected to the swivel part 5 via plug-in couplings.
5 also clarifies that with regard to the positioning of the swivel joint in the frame there is a variability in the invention, which allows adaptation to the respective circumstances, but does not fundamentally change the basic structure of the radiator.

Fig. 6 zeigt schließlich eine Ausführungsform der Erfindung, die verdeutlicht, daß das Trägerteil 1 durch stabförmige Ver­längerungen 16 ergänzt werden kann, wobei diese Verlänge­rungsteile nicht notwendigerweise geradlinig ausgebildet sein müssen. Wenn beispielsweise ein Vorschaltgerät 17 mit der Stromschiene 14 direkt gekuppelt ist, so kann der Strah­ler über ein elektrisches Kabel mit diesem Vorschaltgerät 17 verbunden sein und beispielsweise ein Zündgerät 13 mit dem Schwenkteil 5 gekoppelt werden, so daß das Zundgerät mög­lichst nahe der zugehörigen Lampe gelegen ist.6 finally shows an embodiment of the invention, which illustrates that the carrier part 1 can be supplemented by rod-shaped extensions 16, these extension parts not necessarily having to be straight. If, for example, a ballast 17 is directly coupled to the busbar 14, the radiator can be connected to this ballast 17 via an electrical cable and, for example, an igniter 13 can be coupled to the swivel part 5, so that the ignition device is located as close as possible to the associated lamp .

Von besonderem Vorteil ist es, die zumindest in einem Be­reich von 90° mögliche Verschwenkung des Leuchtmittels über eine fernsteuerbare Verstellvorrichtung vorzunehmen, da die Strahler häufig schwer zugänglich sind und dennoch unter­schiedliche Abstrahlrichtungen zumindest von Zeit zu Zeit realisiert werden müssen. Zu diesem Zweck wird vorzugsweise ein Memory-Metall im Schwenkbereich derart angeordnet, daß durch Beaufschlagung des Memory-Metalls mit einem Strom defi­nierter Stärke ein Verschwenken des Leuchtmittels erfolgt, was vor allem deshalb problemfrei möglich ist, weil diese Verschwenkung nur geringe Stellkräfte erfordert und zwar auf­grund der Austarierung zwischen Leuchtmittel und Schwenkteil 5 bezüglich des Schwenkgelenks 3. Es kann dabei die Ausge­staltung derart gewählt sein, daß ein Verschwenken des Strah­lers in Richtung einer Vergrößerung des Winkels zwischen Ba­sisteil 4 und Schwenkteil 5 aufgrund von Schwerkraftwirkung erfolgt und die Rückstellung über das Memory-Metall vorgenom­men wird. In entsprechenderweise kann aber auch eine Hilfsfe­der eingesetzt werden. Schließlich ist es auch möglich, die Verstellung über einen in die Stabstruktur des Trägerteils integrierten Kleinmotor zu realisieren. Von Bedeutung ist in allen Fällen einer gesteuerten Strahlerverschwenkung die be­nötigte geringe Stellkraft als Folge der gewichtsmäßig ausge­glichenen Teile beiderseits der Schwenkachse 3.It is particularly advantageous to carry out the pivoting of the illuminant, which is possible at least in a range of 90 °, by means of a remotely controllable adjusting device, since the spotlights are often difficult to access and nevertheless different radiation directions have to be implemented at least from time to time. For this purpose, a memory metal is preferably arranged in the swiveling range in such a way that when the memory metal is acted upon by a current of a defined intensity, the illuminant is swiveled, which is possible above all without problems because this swiveling requires only small actuating forces, specifically because the balancing between the lamp and the swivel part 5 with respect to the swivel joint 3. The configuration can be chosen such that swiveling of the spotlight in the direction of an increase in the angle between the base part 4 and swivel part 5 takes place due to the action of gravity, and the resetting via the memory metal is made. Correspondingly, an auxiliary spring can also be used. Finally, it is also possible that Realization via a small motor integrated in the rod structure of the support part. The low actuating force required as a result of the weight-balanced parts on both sides of the pivot axis 3 is important in all cases of controlled lamp pivoting.

Die Integration einer Fernsteuereinrichtung, insbesondere einer Infrarot-Fernsteuereinheit bereitet keine Schwierigkei­ten und ist mit herkömmlichen Mitteln realisierbar.The integration of a remote control device, in particular an infrared remote control unit, presents no difficulties and can be implemented using conventional means.
