Leuchte, insbesondere Steh- bzw. Tischleuchte mit ausziehbarem Lichtkopf Luminaire, in particular floor or table lamp with telescopic light head
Die vorliegende Erfindung betrifft eine Leuchte gemäß dem Oberbegriff des Anspruchs 1 , welche einen gegenüber einem Trägerarm ausziehbaren Lichtkopf zur Aufnahme der Lichtquelle sowie eine sich bis zum Lichtkopf erstreckende Stromversorgungsleitung aufweist. Insbesondere betrifft die vorliegende Erfindung eine Steh- bzw. Tischleuchte.The present invention relates to a lamp according to the preamble of claim 1, which has a relative to a support arm extendable light head for receiving the light source and extending to the light head power supply line. In particular, the present invention relates to a floor or table lamp.
Tischleuchten finden bei Büroarbeitsplätzen zunehmend Verwendung, da sie die Möglichkeit bieten, einzelne Arbeitsplätze individuell auszuleuchten. Das sie verhältnismäßig wenig Platz beanspruchen, kann durch eine geeignete Anordnung der Leuchte auf dem Arbeitstisch eine Ausleuchtung in gewünschter Weise erzielt werden, wobei die Beleuchtungsmöglichkeiten zusätzlich dadurch verbessert werden können, dass gewisse Einstellmöglichkeiten für die Leuchte bestehen. So ist es bspw. bekannt, den an einem Trägerarm angeordneten Lichtkopf verstellbar, bspw. dreh- oder verschwenkbar auszugestalten, um die Ausleuchtung an individuelle Wünsche anzupassen.Table lamps are increasingly being used in office workplaces because they offer the possibility to illuminate individual workplaces individually. The fact that they require relatively little space, illumination can be achieved in the desired manner by a suitable arrangement of the lamp on the work table, the lighting options can be further improved by the fact that certain settings for the lamp exist. Thus, it is known, for example, that the light head arranged on a carrier arm is adjustable, for example, rotatable or pivotable, in order to adapt the illumination to individual wishes.
Aus dem Stand der Technik sind ferner Leuchten bekannt, welche eine weitere Einstellmöglichkeit dadurch eröffnen, dass der Lichtkopf gegenüber einem Trägerarm ausziehbar gelagert ist. Derartige Leuchten sind bspw. in der DE 72 03 745 U oder der DE 91 14 561 U beschrieben. Die erstgenannte Gebrauchsmusterschrift beschreibt bspw. eine Leuchte, bei der der Trägerarm mit dem endseitig angeordneten Lichtkopf teleskopisch ausziehbar ist, um die Gesamtlänge des Trägerarms einstellen zu können. Bei der DE 91 14 561 U hingegen ist ein bogenförmiger Trägerarm vorgesehen, in dem ein länglicher Lichtkopf derart geführt ist, dass dieser gegenüber dem Trägerarm ausgezogen werden kann. In beiden Fällen ist eine Stromversorgungsleitung zur Stromversorgung der Lichtquellen vorgesehen, wobei diese an der Außenseite der Trägerarme entlang geführt ist.Furthermore, lights are known from the prior art, which open a further adjustment possibility in that the light head is mounted extendable relative to a support arm. Such lights are described, for example, in DE 72 03 745 U or DE 91 14 561 U. The first-mentioned utility model describes, for example, a luminaire in which the support arm can be telescopically pulled out with the light head arranged at the end in order to be able to adjust the overall length of the support arm. In DE 91 14 561 U, however, an arcuate support arm is provided, in which an elongate lighthead is guided such that it can be pulled out relative to the support arm. In both cases, a power supply line for powering the light sources is provided, which is guided on the outside of the support arms along.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine neuartige Leuchte anzugeben, welche hinsichtlich ihres äußeren Erscheinungsbildes nochmals gegenüber den bekannten Konstruktionen verbessert ist und gleichzeitig die Möglichkeit bietet, verschiedenste Einstellungen vorzunehmen. Die Aufgabe wird durch eine Leuchte mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.The present invention has for its object to provide a novel lamp, which is improved in terms of their external appearance again compared to the known constructions and at the same time offers the opportunity to make various settings. The object is achieved by a luminaire with the features of claim 1. Advantageous developments of the invention are the subject of the dependent claims.
Die erfindungsgemäße Lösung betrifft wiederum eine Leuchte, bei der ein Lichtkopf gegenüber einem Trägerarm ausziehbar ist, um eine Einstellung der Leuchte zu ermöglichen. Hierbei ist erfindungsgemäß vorgesehen, die Stromversorgungsleitung durch den Trägerarm zu führen, um das Erscheinungsbild der Leuchte zu verbessern. Um dabei trotz allem die Möglichkeit der Verstellung des Lichtkopfs gegenüber dem Trägerarm zu bieten, ist ferner innerhalb des Trägerarms und/oder des Lichtkopf ein Einzugmechanismus zur definierten Aufnahme der Stromversorgungsleitung angeordnet.The solution according to the invention again relates to a luminaire in which a light head can be pulled out with respect to a support arm in order to enable adjustment of the luminaire. This is inventively provided to guide the power supply line through the support arm to improve the appearance of the light. In order to still offer the possibility of adjustment of the light head relative to the support arm, a feed mechanism for defined recording of the power supply line is further arranged within the support arm and / or the light head.
Erfindungsgemäß wird dementsprechend eine Leuchte, insbesondere eine Steh- oder Tischleuchte mit einem gegenüber einem Trägerarm ausziehbaren Lichtkopf zur Aufnahme einer Lichtquelle sowie einer sich bis zum Lichtkopf erstreckenden Stromversorgungsleitung vorgeschlagen, wobei die Leuchte dadurch gekennzeichnet ist, dass die Stromversorgungsleitung zumindest teilweise, vorzugsweise vollständig, durch den Trägerarm geführt ist und in dem Trägerarm und/oder dem Lichtkopf ein Einzugsmechanismus zur definierten Aufnahme der Stromversorgungsleitung angeordnet ist.According to the invention, a luminaire, in particular a floor or table lamp with a pull-out towards a support arm light head for receiving a light source and extending to the light head power supply line is proposed, wherein the lamp is characterized in that the power supply line at least partially, preferably completely, by the support arm is guided and in the support arm and / or the light head, a feed mechanism for the defined recording of the power supply line is arranged.
Durch die erfindungsgemäße Lösung wird erreicht, dass die Stromversorgungsleitung nicht mehr das Erscheinungsbild der Leuchte beeinträchtigt. Insbesondere bilden sich unabhängig von der Einstellung des Lichtkopfs gegenüber dem Trägerarm an der Außenseite der Leuchte keine Kabelschlingen, welche bei bislang bekannten Konstruktionen auftreten können. Hierfür ist insbesondere der Einzugsmechanismus verantwortlich, der sicherstellt, dass in sämtlichen Positionen des Lichtkopfs die Stromversorgungsleitung definiert aufgenommen wird.The inventive solution ensures that the power supply line no longer affects the appearance of the lamp. In particular, regardless of the setting of the light head relative to the support arm on the outside of the lamp no cable loops, which may occur in previously known constructions. For this purpose, in particular the collection mechanism is responsible, which ensures that in all positions of the lighthead, the power supply line is recorded in a defined manner.
Vorzugsweise ist der Lichtkopf gegenüber dem Trägerarm teleskopisch ausziehbar, wobei sowohl ein lineares Ausziehen als auch ein bogenförmiges Ausziehen vorgesehen sein könnte. Der Einzugsmechanismus, der nachfolgend noch näher beschrieben wird, umfasst vorzugsweise eine Rollenumlenkung, wobei die Stromversorgungsleitung als Flachbandkabel ausgeführt ist.Preferably, the light head is telescopically extendable relative to the support arm, wherein both a linear extension and a curved extension could be provided. The feed mechanism, which will be described in more detail below, preferably comprises a roller deflection, wherein the power supply line is designed as a ribbon cable.
Im Falle der Verwendung der erfindungsgemäßen Leuchte als Tischleuchte ist die Lichtquelle vorzugsweise durch eine oder mehrere LEDs gebildet. Um in diesem Fall weitere Verstellmöglichkeiten zur individuellen Ausleuchtung zu ermöglichen, kann ferner vorgesehen sein, dass die Leuchte eine verstellbare Reflektoranordnung aufweist. Diese kann insbesondere durch zwei zu beiden Seiten der Lichtquelle angeordnete, schwenkbar gelagerte Reflektoren gebildet sein, wobei dann weiterhin eine Einstellvoπϊchtung zur Verstellung der beiden Reflektoren vorgesehen ist. Die Lichtquelle und/oder die Reflektoren sind hierbei vorzugsweise mit einem Kühlkörper gekoppelt.In the case of using the lamp according to the invention as a table lamp, the light source is preferably formed by one or more LEDs. To allow in this case further adjustment options for individual illumination, can be further provided that the lamp has an adjustable reflector assembly. This can be formed in particular by two arranged on both sides of the light source, pivotally mounted reflectors, in which case further Einstellvoπϊchtung is provided for adjusting the two reflectors. The light source and / or the reflectors are in this case preferably coupled to a heat sink.
Die Bedienung der erfindungsgemäßen Leuchte kann vorzugsweise durch am Lichtkopf befindliche Bedienelemente vorgenommen werden, wobei diese Bedienelemente insbesondere zum Verstellen des Lichtkopfs gegenüber demThe operation of the luminaire according to the invention can preferably be carried out by controls located on the light head, these controls in particular for adjusting the light head relative to the
Trägerarm vorgesehen sind, gleichzeitig allerdings auch ein Ein- und Ausschalten bzw. ein Einstellen der Helligkeit ermöglichen können. Hierzu kann das Bedienelement bspw. als drehbarer Stift ausgeführt sein, der zusätzlich auch eine eigenständige Beleuchtung aufweisen kann, um die Auffindbarkeit der Leuchte weiter zu verbessern.Carrier arm are provided, but at the same time also enable switching on and off or adjusting the brightness. For this purpose, the control element, for example, be designed as a rotatable pin, which may also have an independent lighting to further improve the findability of the light.
Nachfolgend soll die Erfindung anhand der beiliegenden Zeichnung näher erläutert werden. Es zeigen:The invention will be explained in more detail with reference to the accompanying drawings. Show it:

Fig. 6 eine weitere Schnittdarstellung des vorderen Endbereichs des Lichtkopfs.Fig. 6 is a further sectional view of the front end portion of the light head.
Bei der in Fig. 1 dargestellten und allgemein mit dem Bezugszeichen 1 versehenen erfindungsgemäßen Leuchte handelt es sich um eine sog. Tischleuchte, welche insbesondere zur Ausleuchtung von Schreibtischarbeitsplätzen vorgesehen ist. Anzumerken ist allerdings, dass die Erfindung nicht auf derartige Tischleuchten beschränkt ist. Sie kann bspw. auch bei Stehleuchten zum Einsatz kommen. Auch bei Wand- oder Deckenleuchten, bei denen ein Trägerarm unmittelbar an einer Wand und/oder Decke befestigt ist und der Lichtkopf gegenüber dem Trägerarm verstellbar ausgestaltet sein soll, könnte die Erfindung verwendet werden. Die in Fig. 1 dargestellte Tischleuchte 1 weist zunächst einen Leuchtenfuß 2 mit elektrischen Anschlussmitteln 3 sowie einen sich von dem Leuchtenfuß 2 nach oben erstreckenden Trägerarm 5 auf, der abgewinkelt ausgestaltet ist derart, dass sich ein erster Teil 5a vertikal von dem Leuchtenfuß 2 nach oben erstreckt und ein zweiter Teil 5b horizontal ausgerichtet ist. Der Trägerarm 5, genaugenommen der horizontale Teil 5b hiervon dient zur Halterung eines nachfolgend noch näher beschriebenen Lichtkopfs 10, der eine längliche Gestalt aufweist und an dessen vorderen Ende einerseits die Lichtquellen und andererseits ein Bedienelement 30, über das die Leuchte 1 bedient werden kann, angeordnet sind. Hierunter ist zu verstehen, dass sowohl - wie nachfolgend beschrieben - die Stellung des Lichtkopfs 10 verändert werden kann als auch die Lichtquellen ein- und ausgeschaltet bzw. in ihrer Helligkeit eingestellt werden können.In the illustrated in Fig. 1 and generally provided with the reference numeral 1 lamp according to the invention is a so-called. Table lamp, which is particularly intended for the illumination of desk workstations. It should be noted, however, that the invention is not limited to such table lamps. It can also be used, for example, in floor lamps. Even with wall or ceiling lights in which a support arm is attached directly to a wall and / or ceiling and the light head is designed to be adjustable relative to the support arm, the invention could be used. The table lamp 1 illustrated in FIG. 1 initially has a lamp base 2 with electrical connection means 3 and a support arm 5 extending upward from the lamp base 2, which is angled so that a first part 5a extends vertically from the lamp base 2 upwards extends and a second part 5b is aligned horizontally. The support arm 5, to be precise the horizontal part 5b thereof, serves to support a lighthead 10 which is described in more detail below and which has an elongated shape and at its front end the light sources on the one hand and an operating element 30 via which the luminaire 1 can be operated are. This is to be understood that both - as described below - the position of the light head 10 can be changed and the light sources can be switched on and off or adjusted in their brightness.
Eine erste grundsätzliche Verstellmöglichkeit für die erfindungsgemäße Leuchte 1 besteht darin, dass der Lichtkopf 10 wie in Fig. 1 dargestellt in Pfeilrichtung gegenüber dem Trägerarm 5 verstellt werden kann. Wie die Darstellung in Fig. 2 zeigt, ist hierzu insbesondere der horizontale Bereich 5b des Trägerarms 5 als nach oben offene U-förmige Schiene ausgestaltet, in der der Lichtkopf 10 teleskopisch aufgenommen ist. Eine Längsverstellung des Lichtkopfs 10 wird nun dadurch ermöglicht, dass im rückwärtigen Bereich des Lichtkopfs 10 drei seitlich über das Gehäuse 11 des Lichtkopfs 10 hervorstehende Rollen 12 angeordnet sind. Diese Rollen 12 greifen in Führungsbahnen 6 ein, welche an den Innenseiten der Seitenwände 7 des Trägerarms 5 ausgebildet sind. Auf diese Weise wird ein leichtgängiges Verstellen des Lichtkopfs 10 ermöglicht, wobei gleichzeitig durch die Rollen 12 in den Schienen 6 eine definierte Führung gegeben ist. Über nicht näher dargestellte Begrenzungselemente kann ferner sichergestellt werden, dass der Verstellbereich für den Lichtkopf 10 auf einen bestimmten Bereich beschränkt ist. Insbesondere soll ein Herausziehen des Lichtkopfs 10 derart, dass die Führungsrollen 12 sichtbar sind, vermieden werden.A first basic adjustment for the lamp 1 according to the invention is that the light head 10 as shown in Fig. 1 can be adjusted in the direction of arrow relative to the support arm 5. As the illustration in Fig. 2 shows, in particular the horizontal portion 5b of the support arm 5 is designed as an upwardly open U-shaped rail, in which the light head 10 is telescopically received. A longitudinal adjustment of the light head 10 is now made possible by the fact that in the rear region of the light head 10 three laterally projecting beyond the housing 11 of the light head 10 rollers 12 are arranged. These rollers 12 engage in guideways 6, which are formed on the inner sides of the side walls 7 of the support arm 5. In this way, a smooth adjustment of the light head 10 is made possible, at the same time given by the rollers 12 in the rails 6 a defined leadership. It is also possible to ensure, via limiting elements not shown, that the adjustment range for the light head 10 is restricted to a certain range. In particular, a pulling out of the light head 10 is such that the guide rollers 12 are visible, can be avoided.
Die Unterseite des Lichtkopfs 10 ist in Fig. 3 gezeigt, wobei dieser Darstellung entnehmbar ist, dass im vorderen Bereich des Lichtkopfs 10 die Lichtquellen angeordnet sind. Es handelt sich hierbei um eine Reihenanordnung mehrerer LEDs 15, wobei selbstverständlich auch andere Lichtquellen zum Einsatz kommen könnten. Im Falle einer Tischleuchte wird das von den LEDs abgegebene Licht vorzugsweise asymmetrisch abgegeben, da derartige Leuchten in der Regel auf der von dem Arbeitenden aus gesehen gegenüberliegenden Seite des Tisches platziert werden und einen bestimmten Arbeitsbereich des Tisches ausleuchten sollen. Um diese asymmetrische Lichtverteilung zu ermöglichen, sind zu beiden Seiten der LEDs 15 Rinnenreflektoren 16 angeordnet, welche verschwenkbar gelagert sind. Über ein Einstellrad 17 können beide Rinnenreflektoren 16 wahlweise in verschiedene Richtungen verschwenkt werden, um die Lichtabgabe zu beeinflussen. Durch diese Flexibilität ist gewährleistet, dass die Leuchte 1 wahlweise an verschiedenen Seiten der zu beleuchtenden Arbeitsfläche aufgestellt werden kann.The underside of the light head 10 is shown in Fig. 3, wherein this representation is removable, that in the front region of the light head 10, the light sources are arranged. This is a series arrangement of several LEDs 15, although of course other light sources could be used. In the case of a table lamp, the light emitted by the LEDs is preferably emitted asymmetrically, since such lights are usually placed on the opposite side of the table from the worker and should illuminate a particular work area of the table. Around To allow asymmetric light distribution, 15 channel reflectors 16 are arranged on both sides of the LEDs, which are pivotally mounted. Via a dial 17, both channel reflectors 16 can be selectively pivoted in different directions in order to influence the light output. This flexibility ensures that the lamp 1 can be placed either on different sides of the working surface to be illuminated.
Der interne Aufbau des Lichtkopfs 10 kann der Darstellung in Fig. 4 entnommen werden, welche den Lichtkopf 10 ohne die äußere Umkleidung 11 zeigt. Im rückwärtigen Bereich des Lichtkopfs 10 sind hierbei die bereits angesprochenen Führungsrollen 12 angeordnet, während sich am vorderen Ende das Beleuchtungsmodul 18 mit den LEDs sowie den Reflektoren befindet. Ferner ist auch eine mit dem Bedienelement 30 gekoppelte Steuervorrichtung 19 vorgesehen, über welche die Ansteuerung des Beleuchtungsmoduls 18 vorgenommen wird.The internal structure of the light head 10 can be seen in the illustration in FIG. 4, which shows the light head 10 without the outer casing 11. In the rear region of the light head 10 in this case the already mentioned guide rollers 12 are arranged, while located at the front end of the lighting module 18 with the LEDs and the reflectors. Furthermore, a control device 19 coupled to the control element 30 is provided, via which the control of the lighting module 18 is performed.
Eine weitere wesentliche Komponente des Lichtkopfs 10 ist ein allgemein mit dem Bezugszeichen 20 versehener Einzugsmechanismus, der zur definierten Führung und Aufnahme einer Stromversorgungsleitung dient, über welche die Stromversorgung des Beleuchtungsmoduls 18 erfolgt. Aufgabe dieses Einzugsmechanismusses 20 ist es, die Stromversorgungsleitung in jeder Stellung des Lichtkopfs 10 derart aufzunehmen bzw. zu führen, dass sich keine ungewollten Schlingen der Stromversorgungskabel ergeben, welche zu einer Beeinträchtigung entweder des Aussehens der Leuchte 1 oder der Verstellbarkeit des Lichtkopfs 10 fuhren könnten. Der Aufbau und die spezielle Funktionsweise des Einzugsmechanismusses 20 soll nachfolgend anhand der Fig. 4 und 5 näher erläutert werden.Another essential component of the light head 10 is a generally designated by the reference numeral 20 feed mechanism, which serves for the defined guidance and receiving a power supply line, via which the power supply of the lighting module 18 takes place. The object of this intake mechanism 20 is to receive or guide the power supply line in any position of the light head 10 such that no unwanted loops of the power supply cables result, which could lead to an impairment of either the appearance of the light 1 or the adjustability of the light head 10. The construction and the special mode of operation of the pull-in mechanism 20 will be explained in more detail below with reference to FIGS. 4 and 5.
Generell erfolgt die Stromversorgung des LED-Moduls 18 dadurch, dass zunächst eine Stromversorgungsleitung durch den Trägerarm 5 bis zu dessen vorderen Ende geführt ist. Hier erfolgt an der Stelle A über eine Öffnung O (welche in Fig. 3 erkennbar ist) in der Unterseite des Lichtkopfs 10 eine Verbindung mit einem Flachbandkabel 21, welches einerseits an dem vorderen Ende des Trägerarms 5 angreift und andererseits mit seinem vorderen Ende mit Stromversorgungsdrähten 22 verbunden ist, welche zu dem Beleuchtungsmodul 18 führen. Das Flachbandkabel 21 weist eine Länge auf, welche in jeglicher Stellung des Lichtkopfs 10 eine Verbindung von dem Trägerarm 5 zu den Kabeln 22 sicherstellt. Gleichzeitig ist allerdings das Flachbandkabel 12 über den Einzugsmechanismus 20 derart gelagert, dass keine losen Schlingen auftreten, sobald der Lichtkopf 10 gegenüber dem Trägerarm 5 verschoben wird. Diese Einzugsmechanismus 20 weist als zentrale Elemente vier Führungsrollen 22 bis 25, um die das Flachbandkabel 21 entsprechend der Darstellung schlingenförmig geführt ist. Während die beiden hinteren Führungsrollen 22 und 23 fest in dem Gehäuse des Lichtkopfs 1 1 angeordnet sind, sind die beiden vorderen Führungsrollen 24 und 25 gemeinsam an einer schlittenartigen Halterung 26 befestigt, wobei diese Halterung in Längsrichtung des Lichtkopfs 10 gleiten kann. Über eine Zugfeder 27 ist das Führungsteil 26 ferner mit einer Halterung 28 für die Kabel 22 verbunden. Die Fig. 4 und 5 zeigen hierbei die Anordnung der Führungsrollen 22 bis 25 bei ausgezogenem Lichtkopf 10.In general, the power supply of the LED module 18 takes place in that first a power supply line is guided through the support arm 5 to its front end. Here takes place at the point A via an opening O (which can be seen in Fig. 3) in the bottom of the light head 10 is a connection with a ribbon cable 21, which acts on the one hand to the front end of the support arm 5 and on the other hand with its front end with power supply wires 22, which lead to the lighting module 18. The ribbon cable 21 has a length which ensures a connection from the support arm 5 to the cables 22 in any position of the light head 10. At the same time, however, the ribbon cable 12 is mounted on the feed mechanism 20 such that no loose loops occur as soon as the light head 10 is moved relative to the support arm 5. This feed mechanism 20 has as central elements four guide rollers 22 to 25, around which the ribbon cable 21 is looped according to the representation. While the two rear guide rollers 22 and 23 are fixedly arranged in the housing of the light head 1 1, the two front guide rollers 24 and 25 are fastened together on a carriage-like holder 26, said holder can slide in the longitudinal direction of the light head 10. Via a tension spring 27, the guide member 26 is further connected to a bracket 28 for the cable 22. FIGS. 4 and 5 show the arrangement of the guide rollers 22 to 25 with the light head 10 pulled out.
Wird nunmehr der Lichtkopf 10 gegenüber dem Trägerarm 5 verstellt, bspw. weiter in den Trägerarm 5 eingeschoben, so hat dies zur Folge, dass das Lichtkopfgehäuse über das vordere Kontaktierungsende 21a des Flachbandkabels 21 nach hinten geschoben wird. Hierzu rollt das Kabel 21 über die verschiedenen Führungsrollen 22 bis 25 und durch die untere Öffnung in dem Lichtkopf 10 derart ab, dass es an der Unterseite des Lichtkopfs 10 entlang geführt wird. Das Nachführen des Flachbandkabels 21 wird dabei dadurch ermöglicht, dass der Schlitten 26 mit den beiden vorderen Führungsrollen 24 und 25 in Richtung der hinteren Führungsrollen 22 und 23 gezogen wird, wodurch ein Längenausgleich ermöglicht wird. In jeglicher Stellung ist allerdings das Flachbandkabel 21 in definierter Weise über die Führungsrollen 22 bis 25 geführt, so dass keine unerwünschten Schlingen auftreten. Ferner wird durch die Zugfeder 27 sichergestellt, dass das Flachbandkabel 21 grundsätzlich unter Zug gesetzt ist.Now, if the light head 10 is adjusted relative to the support arm 5, for example. Further inserted into the support arm 5, this has the consequence that the light head housing is pushed over the front contacting end 21a of the ribbon cable 21 to the rear. For this purpose, the cable 21 rolls over the various guide rollers 22 to 25 and through the lower opening in the light head 10 from such that it is guided along the underside of the light head 10 along. The tracking of the ribbon cable 21 is thereby made possible that the carriage 26 is pulled with the two front guide rollers 24 and 25 in the direction of the rear guide rollers 22 and 23, whereby a length compensation is made possible. In any position, however, the ribbon cable 21 is guided in a defined manner over the guide rollers 22 to 25, so that no unwanted loops occur. Furthermore, it is ensured by the tension spring 27 that the ribbon cable 21 is basically put under train.
Durch diesen speziellen Einzugsmechanismus 20 kann also eine Verstellung des Lichtkopfs 10 erfolgen, wobei gleichzeitig sichergestellt ist, dass die Stromversorgungsleitung für die Leuchte generell in definierter Weise in den verschiedenen Gehäuseteilen der Leuchte aufgenommen wird, so dass das Erscheinungsbild der Leuchte nicht negativ beeinflusst wird.Thus, an adjustment of the light head 10 can be carried out by this special feed mechanism 20, wherein at the same time it is ensured that the power supply line for the lamp is generally taken in a defined manner in the various housing parts of the lamp, so that the appearance of the lamp is not adversely affected.
Fig. 6 zeigt abschließend eine Schnittdarstellung des vorderen Bereichs des Lichtkopfs 10, wobei einerseits die LEDs 15 sowie andererseits die zu beiden Seiten der LEDs 15 angeordneten Rinnenreflektoren 16 erkennbar sind. Diese können - wie bereits erwähnt — gemeinsam über das Einstellrad 17 verstellt bzw. verschwenkt werden, so dass eine Lichtabgabe in gewünschter Richtung eingestellt werden kann. DasFinally, FIG. 6 shows a sectional view of the front region of the light head 10, on the one hand the LEDs 15 and on the other hand the channel reflectors 16 arranged on both sides of the LEDs 15 being recognizable. These can - as already mentioned - be adjusted or pivoted together via the adjusting wheel 17, so that a light output can be adjusted in the desired direction. The
Beleuchtungsmodul ist hierbei mit einem Kühlkörper 31 gekoppelt, um die Wärme abzuführen. Die Bedienung der Leuchte 1 erfolgt über den Stift 30, der zunächst einmal ein Angriffselement darstellt, mit dessen Hilfe der Lichtkopf 10 gegenüber dem Trägerarm 5 verschoben werden kann. Gleichzeitig ist der Stift 30 auch ein Bedienelement zum Ein- und Ausschalten der Leuchte 1, was durch ein Verdrehen des Stifts 30 erfolgt. Hierbei kann bspw. auch vorgesehen sein, dass die Helligkeit der LEDs 15 mit Hilfe einer Veränderung der Drehstellung des Stifts 30 eingestellt werden kann. Weiterhin kann vorgesehen sein, dass der Drehstift 30 selbst - bspw. mittels einer weiteren LED - beleuchtet wird, um ein Auffinden der Leuchte zu ermöglichen. Die Ansteuerelektronik für die Lichtquellen ist dabei ferner vorzugsweise derart ausgeführt, dass in einer Position des Lichtkopfs 10, in der die Lichtquellen durch den Trägerarm 5 verdeckt werden, eine Zwangsabschaltung erfolgt.Lighting module is in this case coupled to a heat sink 31 to dissipate the heat. The operation of the lamp 1 via the pin 30, which initially represents an attack element, with the aid of the light head 10 can be moved relative to the support arm 5. At the same time, the pin 30 is also an operating element for switching the lamp 1 on and off, which is done by rotating the pin 30. In this case, for example, it can also be provided that the brightness of the LEDs 15 can be adjusted by means of a change in the rotational position of the pin 30. Furthermore, it can be provided that the pivot pin 30 itself - for example, by means of another LED - is illuminated to allow locating the lamp. The control electronics for the light sources is further preferably designed such that in a position of the light head 10, in which the light sources are covered by the support arm 5, a forced shutdown takes place.
Letztendlich wird also eine Leuchte geschaffen, welche eine Vielzahl von Einstellmöglichkeiten bietet, wobei gleichzeitig durch eine entsprechende Aufnahme der Kabel bzw. Stromversorgungsleitungen sichergestellt ist, dass in jeglichem Zustand der Leuchte deren äußeres Erscheinungsbild nicht beeinträchtigt wird. Ultimately, therefore, a lamp is created, which offers a variety of settings, while ensuring at the same time by an appropriate recording of the cable or power supply lines that in any state of the lamp whose appearance is not affected.
