Description

Bezeichnung der Erfindung: Leuchte mit in der Länge veränderbarer  Description of the invention: luminaire with variable length
Tragstrebe für ein Leuchtmittel  Support strut for a light source
Die vorliegende Erfindung betrifft eine Leuchte mit einem Leuchtensockel, einer mittels des Leuchtensockels gehaltenen länglichen Tragstrebe, die in ihrer Länge veränderbar ist, und einem an der Tragstrebe angeordneten Leuchtmittel . The present invention relates to a lamp having a lamp base, an elongated supporting strut held by means of the lamp socket, which can be changed in its length, and a lamp arranged on the support strut.
Bei der Entwicklung der Leuchtentechnik gibt es eine Vielzahl von unterschiedlichen Konstruktionen im Stand der Technik. Neben der guten Lichtausbeute sind insbesondere Funktionalität und Leichtbau ein oft gewünschtes Kriterium. Insbesondere wird z. B. bei Arbeitsplatz- oder Leseleuchten mit einem an einer Tragstrebe befestigten Leuchtmittel gefordert, dass durch Verstellung der Trag strebe die Position und/oder die Ausrichtung des Leuchtmittels individuell eingestellt werden kann. Hierzu sind aus dem Stand der Technik Konstruktionen bekannt, bei denen die Länge der Tragstrebe verändert werden kann. In the development of lighting technology, there are a variety of different constructions in the prior art. In addition to the good light output, in particular functionality and lightweight construction are often a desired criterion. In particular, z. B. required in workplace or reading lights with a fastened to a support strut bulbs that strive by adjusting the support, the position and / or orientation of the light source can be adjusted individually. For this purpose, constructions are known from the prior art, in which the length of the support strut can be changed.
So ist aus der Gebrauchsmusterschrift DE 202 10 215 U l bereits eine Leuchte mit einer Tragstrebe bekannt, bei der die Tragstrebe in ihrer Länge veränderbar ausgestaltet ist, und zumindest teilweise aus einem bandförmigen, unter Vorspannung stehenden Material gebildet ist, das von einer stabilen gestreckten Stellung in eine aufgerollte Stellung und umgekehrt überführbar ist. Thus, from the utility model DE 202 10 215 U l already a lamp with a support strut known in which the support strut is designed to be variable in length, and at least partially formed of a band-shaped, biased material from a stable extended position in a rolled-up position and vice versa is feasible.
Nachteilig an der aus der DE 202 10 215 Ul vorbekannten Konstruktion ist jedoch, dass es in der Praxis schwierig ist, eine aufrollbar Tragstrebe bereitzustel¬ len, die in ihrer gestreckten Stellung eine ausreichende mechanische Stabilität aufweist. A disadvantage of the previously known from DE 202 10 215 Ul construction, however, is that it is difficult in practice, a roll-up support strut bereitzustel ¬ len, which has sufficient mechanical stability in its extended position.
Aufgabe der vorliegenden Erfindung ist es daher, eine Leuchte anzugeben, die unter Beibehaltung der Funktionalität der aus der DE 202 10 215 U l bekannten Leuchte eine deutlich verbesserte mechanische Stabilität der Tragstrebe aufweist. The object of the present invention is therefore to provide a luminaire which, while retaining the functionality of the luminaire known from DE 202 10 215 U1, has a significantly improved mechanical stability of the support strut.
Gelöst wird diese Aufgabe durch eine Leuchte mit den Merkmalen des Hauptanspruchs. Den Unteransprüchen sind vorteilhafte Ausgestaltungen und Weiterbildungen zu entnehmen. Eine erfindungsgemäße Leuchte umfasst einen Leuchtensockel und eine mittels des Leuchtensockels gehaltene längliche Tragstrebe, die in ihrer Länge veränderbar ist. Weiterhin umfasst die erfindungsgemäße Leuchte ein an der Tragstrebe angeordnetes Leuchtmittel . Unter dem Begriff Leuchtensockel sollen im Kontext der vorliegenden Anmeldung sämtliche Einrichtungen verstanden werden, die als Stand- oder Anbringungsmittel der Leuchte geeignet sind. Auch muss die Tragstrebe nicht unmittelbar am Leuchtensockel angeordnet sein, sondern kann sich unter Zwischenfügung von anderen Tragelementen auch in Abstand von diesem erstrecken. This object is achieved by a luminaire with the features of the main claim. The dependent claims are advantageous embodiments and developments refer to. A luminaire according to the invention comprises a luminaire base and an elongated support strut held by means of the luminous socket, which can be changed in its length. Furthermore, the luminaire according to the invention comprises a light-emitting means arranged on the support strut. The term light socket in the context of the present application, all devices are to be understood that are suitable as a stand or attachment means of the lamp. Also, the support strut does not need to be located directly on the lamp base, but may also extend at a distance from this with the interposition of other support elements.
Erfindungsgemäß besteht nun die Tragstrebe aus mindestens zwei Bändern, die jeweils von einer aufgerollten Stellung in eine gestreckte Stellung oder umgekehrt überführbar sind, für sich selbst aufrollbar sind und mindestens in einem Punkt mechanisch verbunden sind, dergestalt dass sich die Bänder in der gestreckten Stellung mechanisch aneinander abstützen. Bevorzugt weisen die Bänder dabei in ihrer gestreckten Stellung quer zu ihrer Erstreckungsrichtung in einer ersten Richtung eine niedrige Knicksteifigkeit auf, und in einer der ersten Richtung entgegen gerichteten zweiten Richtung eine hohe Knicksteifigkeit. Unter Knicksteifigkeit soll die Fähigkeit verstanden werden, unter Einwirkung einer quer zur Erstreckungsrichtung des Bands gerichteten Kraft die gestreckte Stellung beizubehalten. Wie erwähnt besteht die Tragstrebe bei der vorliegenden Erfindung aus mindestens zwei Bändern, die sich in der gestreckten Stellung gegenseitig stützen. Dies verbessert die Konstruktion der aus dem Gebrauchsmuster DE 202 10 215 U l genannten Leuchte dahingehend, dass keine stabile gestreckte Stellung jedes einzelnen Bandes für sich alleine mehr benötigt wird . Vielmehr ergibt sich eine ausreichende mechanische Stabilität der Tragstrebe in ihrer gestreckten Stellung gerade dadurch, dass sich die aufrollbaren Bänder, die u.U. für sich alleine keine oder keine ausreichende Stabilität, insbesondere Knicksteifigkeit, aufweisen, so aneinander abstützen, dass sich in der Summe eine ausreichende mechanische Stabilität ergibt. According to the invention, the support strut now consists of at least two bands, each of which can be moved from a rolled-up position to an extended position or vice versa, can be rolled up for itself and are mechanically connected at least at one point, such that the bands mechanically adjoin one another in the extended position support. In this case, the straps preferably have a low buckling stiffness in their extended position transversely to their extension direction in a first direction, and a high buckling stiffness in a second direction directed counter to the first direction. The term "buckling stiffness" should be understood to mean the ability to maintain the stretched position under the action of a force directed transversely to the direction of extension of the belt. As mentioned, in the present invention, the support strut consists of at least two bands which mutually support one another in the extended position. This improves the construction of the lamp referred to in the utility model DE 202 10 215 U 1 in that no stable stretched position of each individual strip is required on its own. Rather, there is sufficient mechanical stability of the support strut in its extended position just by the fact that the roll-up bands u.U. have no or no sufficient stability on their own, in particular buckling resistance, support one another so that the overall result is sufficient mechanical stability.
Als besonders geeignet haben sich Bänder erwiesen, die ein Profil aufweisen, das quer zur Erstreckungsrichtung des Bands in einer ersten Raumrichtung eine hohe Knicksteifigkeit aufweist, und in einer dazu senkrechten Richtung, die ebenfalls quer zur Erstreckungsrichtung orientiert ist, eine deutlich verminderte Knicksteifigkeit. Beispielhaft seien hierfür bogenförmige Profile genannt, insbesondere U- und V-Profile, aber auch W-Profile bzw. Wellenprofile im Allgemeinen weisen diese vorteilhafte Eigenschaft auf. Werden solche Profile insbesondere„Rücken-an Rücken" verwendet, wobei grundsätzlich aber auch andere Konfigurationen möglich sind, und werden die Bänder an zumindest einem Punkt mechanisch miteinander verbunden, so versteifen sie gegenseitig, so dass eine aus mindestens zwei, ggf. aber auch drei, vier oder mehr Bändern bestehende Tragstrebe eine hohe mechanische Festigkeit, insbesondere eine hohe Knicksteifigkeit in allen Richtungen quer zur Erstreckungsrichtung der Tragstrebe aufweist. Dabei ist es besonders vorteilhaft, wenn die Richtung niedriger Knicksteifigkeit der Bänder in horizontaler Richtung orientiert ist. Particularly suitable bands have proven to have a profile which has a high buckling resistance transversely to the direction of extension of the band in a first spatial direction, and in a direction perpendicular thereto, which is also oriented transversely to the extension direction, a significantly reduced buckling resistance. By way of example, arch-shaped profiles are mentioned for this, in particular U-shaped profiles. and V-profiles, but also W-profiles or wave profiles in general have this advantageous property. If such profiles in particular "back-to-back" used, but in principle, other configurations are possible, and the bands are mechanically connected to each other at least one point, so they stiffen each other, so that one of at least two, but possibly also three , four or more bands existing support strut has a high mechanical strength, in particular a high buckling stiffness in all directions transverse to the extension direction of the support strut.Here it is particularly advantageous if the direction of low buckling stiffness of the bands is oriented in the horizontal direction.
Durch die Verwendung und die speziellen Anordnungen der mindestens zwei Bänder erhöht sich also die Knicksteifigkeit der gesamten Strebe bei gleichzeitig deutlich vereinfachter Konstruktion. Neben Kostenvorteilen wird es hierdurch ermöglicht, die maximale Länge der Tragstrebe wesentlich zu steigern. Dies erhöht erheblich die Funktionalität der Leuchte, da diese nunmehr z. B. sowohl als Tisch, Steh- und Deckenleuchte mit variabler Leuchtmittelposition verwendet werden kann. Due to the use and the special arrangements of the at least two bands thus increases the buckling resistance of the entire strut at the same time significantly simplified design. In addition to cost advantages, this makes it possible to significantly increase the maximum length of the support strut. This significantly increases the functionality of the lamp, as these now z. B. can be used both as a table, floor and ceiling lamp with variable light source position.
Bei der vorliegenden Leuchte kann bevorzugt vorgesehen werden, dass der aufgerollte Teil der Tragstrebe in dem Leuchtensockel angeordnet ist, insbesondere von ihm gehalten wird. Neben Designgründen ist es auch aus praktischen Gründen von Vorteil, den aufgerollten Zustand der Bänder im Leuchtensockel zu verbergen, da die Bänder vor Schmutzablagerungen geschützt werden. In the case of the present luminaire, it can preferably be provided that the rolled-up part of the support strut is arranged in the luminaire base, in particular held by it. In addition to design reasons, it is also advantageous for practical reasons, to hide the rolled up state of the bands in the light socket, since the bands are protected from dirt deposits.
Der Leuchtensockel kann darüber hinaus vorteilhaft so ausgestaltet sein, dass er für die Anbringung der Leuchte z. B. an einer Wand- oder Deckenfläche oder einer Platte eines Möbelstücks geeignet ist. The lamp base can also be advantageously designed so that it is suitable for the attachment of the lamp z. B. on a wall or ceiling surface or a plate of a piece of furniture is suitable.
In der Regel wird jedes Band der Tragstrebe in seinem aufgerollten Zustand einen anderen Querschnitt aufweisen als in seiner gestreckten Stellung. Dies bedeutet, dass beim Ausziehen bzw. Einschieben der Tragstrebe eine mechanisch zu bewirkende Formänderung der Bänder erforderlich ist. Da diese Formänderung wesentlich für das Auszugverhalten der Tragstrebe ist, hat es sich weiterhin als vorteilhaft erwiesen, wenn der Leuchtensockel Umformmittel umfasst, die dazu vorgesehen sind, die Querschnittsform jeweils eines Bandes beim Ausziehen bzw. Einschieben der Tragstrebe zu verändern. Hierzu kann der Leuchtensockel beispielsweise einen Umformbereich für einen einführbaren Teil der Bänder aufweisen, mittels dem die Bänder aufgrund der Formgebung des Umformbereichs kontinuierlich von ihrer Querschnittsform in der aufgerollten Stellung zu ihrer Querschnittsform in ihrer gestreckten Stellung und umgekehrt überführbar sind. Der Umformbereich dient demnach als Führungshilfe zum Überführen der Tragstrebe von einer gestreckten in eine aufgerollte Stellung . Der Benutzer der Leuchte braucht also nur eine Kraft in Längsrichtung der Tragstrebe aufzubringen. Die Umgestaltungsvorgänge, die bei der Überführung von der gestreckten in eine aufgerollte Stellung durchgeführt werden müssen, übernimmt dann der Umformbereich . In general, each band of the support strut in its rolled-up state will have a different cross section than in its extended position. This means that when removing or inserting the support strut a mechanically changing shape of the bands is required. Since this change in shape is essential for the pull-out behavior of the support strut, it has also proved to be advantageous if the lamp base comprises forming means which are intended to change the cross-sectional shape of each band during extension or insertion of the support strut. For this purpose, the For example, lamp base have a forming portion for an insertable part of the bands, by means of which the bands due to the shaping of the forming area continuously from their cross-sectional shape in the rolled-up position to its cross-sectional shape in its extended position and vice versa be transferred. The forming area thus serves as a guide to transfer the support strut from a stretched to a rolled-up position. The user of the lamp thus only needs to apply a force in the longitudinal direction of the support strut. The transformation processes, which must be carried out in the transfer of the stretched in a rolled-up position, then takes over the forming area.
Schließlich kann ergänzend vorgesehen werden, dass die Tragstrebe um eine Drehachse gegenüber der Horizontalen verschwenkt werden kann, und insbesondere in einer vom Benutzer gewünschten Winkellage feststellbar ist. Hierdurch lässt sich die Tragstrebe nicht nur in ihrer Länge verändern, sondern kann auch beliebige Winkellagen einnehmen. Dabei liegt die Drehpunktachse bevorzugt im Bereich des Leuchtensockels und ist horizontal ausgerichtet. Finally, it can be additionally provided that the support strut can be pivoted about an axis of rotation relative to the horizontal, and in particular in a desired angular position can be determined by the user. As a result, the support strut can not only change in length, but can also assume any angular positions. In this case, the pivot axis is preferably in the range of the light socket and is aligned horizontally.
Eine Möglichkeit, die Bänder wie erfindungsgemäß vorgesehen in zumindest einem Punkt miteinander zu verbinden, besteht darin, sie an einer Stelle zu durchbohren und sie formschlüssig durch eine Schraube zu verbinden. Aber auch eine stoffschlüssige Verbindung z. B. über Verschweißen (z. B. mittels Schweißpunkt), Verkleben (z.B. mittels Klebepunkt) oder Verpressen, oder aber auch über formschlüssige Verbindung wie einen Hinterschluss ist grundsätzlich möglich. Bevorzugt ist der zumindest eine mechanische Verbindungspunkt am außenliegenden Ende der Tragstrebe angeordnet. Weiterhinkann er eine mechanische Verbindung zum Leuchtmittel bzw. Leuchtenkopf bereit stellen. One way to connect the bands as provided according to the invention in at least one point with each other, is to pierce them at one point and to connect them positively by a screw. But also a cohesive connection z. B. by welding (eg., By welding point), gluing (for example by means of adhesive point) or pressing, or even via positive connection such as a trailing is basically possible. Preferably, the at least one mechanical connection point is arranged on the outer end of the support strut. Furthermore, he can provide a mechanical connection to the lamp or lamp head.
Des Weiteren können die Bänder elektrisch leitfähig sein. Diese Ausgestaltung führt dazu, dass keine gesonderten, elektrischen Zuleitungen nötig bzw. sichtbar sind . Aus Designgründen ist diese Ausgestaltung von Vorteil. Gemäß einer Variante können die Bänder auch gegeneinander elektrisch isoliert sein. Bevorzugt ist in dieser Ausgestaltung die mindestens eine mechanische Verbindung zwischen den Bändern elektrisch nichtleitend ausgeführt. Insbesondere in dieser Ausgestaltung kann eine Sicherheitsabschaltung in die erfindungsgemäße Leuchte integriert werden. Diese kann in Form einer Überwachungseinrichtung in die Leuchte integriert werden, die den Leitungswiderstand der Bänder sowie ggf. des Leuchtmittels misst. Falls sich der gemessene Widerstand wesentlich ändert, was z.B. bei einem Abknicken der Bänder, d .h. einem mechanischen Versagen der Tragstrebe, auftreten könnte, schaltet die Überwachungseinrichtung die Spannungsversorgung des Leuchtmittels automatisch ab. Eine solche Überwachungseinrichtung kann dabei insbesondere in eine Vorschaltelektronik des Leuchtmittels integriert sein. Furthermore, the bands can be electrically conductive. This configuration means that no separate, electrical leads are necessary or visible. For design reasons, this embodiment is advantageous. According to a variant, the bands may also be electrically isolated from each other. Preferably, in this embodiment, the at least one mechanical connection between the bands is made electrically non-conductive. In particular, in this embodiment, a safety shutdown can be integrated into the lamp according to the invention. This can be integrated in the form of a monitoring device in the lamp, the line resistance of the bands and possibly the Measures bulb. If the measured resistance changes significantly, eg if the bands are bent, ie. a mechanical failure of the support strut, could occur, the monitoring device automatically switches off the voltage supply of the lamp. Such a monitoring device can be integrated in particular in a ballast of the lamp.

Fig. 1 zeigt einerseits Ausführungsbeispiel einer Leuchte 100, die im Wesentlichen einen Leuchtensockel 1, eine sich unter einem einstellbaren Winkel gegen die Horizontale nach oben erstreckende Tragstrebe 2 und einen am freien Ende der Tragstrebe 2 angeordneten Leuchtenschirm 6 umfasst, der ein Leuchtmittel 3, z. B. eine Glühbirne, ein Leuchtstoffröhre oder ein modernes Leuchtmittel auf Halbleiterbasis, aufnimmt. Fig. 1 shows on the one hand embodiment of a lamp 100, which is essentially a lamp base 1, at an adjustable angle to the horizontal upwardly extending support strut 2 and one at the free end the support strut 2 arranged lampshade 6, which comprises a lighting means 3, z. As a light bulb, a fluorescent tube or a modern semiconductor-based light sources, receives.
Der Leuchtensockel 1 ist als Halbkugelförmiges Gehäuse ausgestaltet, in dem der aufgerollte Teil der Bänder 4 nebst zugehöriger Aufrollmechanik 15, eine The lamp base 1 is designed as a hemispherical housing, in which the rolled-up part of the bands 4 together with associated Aufrollmechanik 15, a
Schwenkeinrichtung 13 und eine Vorschaltelektronik 14 zur Ansteuerung des Leuchtmittels 3 auf. Pivoting device 13 and a ballast 14 for controlling the bulb 3.
Die Tragstrebe 2 besteht bei der Leuchte 100 gemäß Fig. 1 aus zwei Bändern 4, die von einer gestreckten Stellung in eine aufgerollte Stellung überführbar sind . In dieser Stellung sind die aufgerollten Enden der Bänder 4 vollständig in der Aufrollmechanik 15 aufgenommen und verschwinden so praktisch vollständig im Leuchtensockel 1. Die Bänder 4 sind aus einem Metallblech (z.B. aus Federstahl) mit einer Stärke von typisch unter 1 Millimeter, bevorzugt unter 0,5 Millimeter, ausgebildet, wobei die Bänder 4 durch eine allseitig aufgebrachte Lackierung oder Kunststoffummantelung elektrisch gegeneinander isoliert sind . Die Bänder 4 dienen als elektrische Zuleitungen für das Leuchtmittel 3. The support strut 2 is in the lamp 100 shown in FIG. 1 of two bands 4, which can be converted from an extended position to a rolled-up position. In this position, the rolled ends of the bands 4 are completely absorbed in the Aufrollmechanik 15 and disappear virtually completely in the light socket 1. The bands 4 are made of a metal sheet (eg spring steel) with a thickness of typically less than 1 millimeter, preferably below 0, 5 mm, formed, wherein the bands 4 are electrically insulated from each other by a coating applied on all sides or plastic coating. The bands 4 serve as electrical leads for the lamp 3.
Die mechanische Verbindung zwischen Leuchtenschirm 6 und Tragstrebe 2 ist in Fig. 3 dargestellt, die eine Ausschnittvergrößerung von Fig. 2 darstellt. Wie aus Fig. 3 ersichtlich ist sind die Bänder 4 an ihrem außenliegenden Ende mittels einer Schraube 7 mit einem länglichen Befestigungsansatz 12 des Leuchtenschirms 6 verbunden. Hierdurch wird eine gelenkige Verbindung zwischen The mechanical connection between lampshade 6 and support strut 2 is shown in Fig. 3, which represents an enlarged detail of Fig. 2. As is apparent from Fig. 3, the bands 4 are connected at its outer end by means of a screw 7 with an elongate attachment lug 12 of the lampshade 6. This will create a hinged connection between
Leuchtenschirm 6 und Tragstrebe 2 realisiert. Weiterhin ist der Befestigungsansatz 12 quer zu seiner Längsachse geteilt, wobei die beiden Teile auf geeignete Weise um die gemeinsame Längsache gegeneinander verdrehbar aneinander gelagert sind. Insgesamt ergibt sich hieraus die Verstellbarkeit des Lampshade 6 and support strut 2 realized. Furthermore, the attachment lug 12 is divided transversely to its longitudinal axis, wherein the two parts are mounted in a suitable manner to each other about the common longitudinal axis against each other rotatable. Overall, this results in the adjustability of
Leuchtenschirms 6, die in Fig. 1 durch die entsprechenden Pfeile am Lampshade 6, in Fig. 1 by the corresponding arrows on
Leuchtenschirm 6 angedeutet ist, nämlich eine Verdrehbarkeit des Lampshade 6 is indicated, namely a twistability of
Leuchtenschirms 6 gegen die Längsachse der Tragstrebe 2 und eine Lampshade 6 against the longitudinal axis of the support strut 2 and a
Verschwenkbarkeit des Leuchtenschirms 6 gegen die Horizontale. Pivotability of the lampshade 6 against the horizontal.
Darüber hinaus stellt die Schraube 7 in Zusammenwirkung mit dem Befestigungsansatz 12 eine punktuelle mechanische Verbindung zwischen den Bändern 4 dar, über die sich die Bänder 4 aneinander abstützen wie dies erfindungsgemäß vorgesehen ist. Der Befestigungsansatz 12 hält dabei die Bandenden in ei- nem gewissen Abstand voneinander, so dass sich bei einem Schnitt durch die Bänder 4 entlang der Linie I-I in Fig. 1 die Ansicht gemäß Fig . 5 ergibt. Aus dieser Figur ist auch ersichtlich, dass jedes Band 4 im gestreckten Zustand quer zur seiner Erstreckungsrichtung einen bogenförmigen Querschnitt aufweist, wie aus Fig. 7 ersichtlich ist, die eine Schnittdarstellung durch die Tragstrebe 2 entlang der Linie I-I in Fig . 1 zeigt. Dieser bogenförmige Querschnitt hat zur Folge, dass jedes einzelne Band 4 in der quer zur Erstreckungsrichtung verlaufenden y- Richtung gemäß Fig. 7 eine deutlich geringere Knicksteifigkeit hat als in der ebenfalls quer zur Erstreckungsrichtung verlaufenden x-Richtung. Weiterhin hat der bogenförmige Querschnitt zur Folge, dass die Knicksteifigkeit des in Fig. 5 mit 4.1 bezeichneten Bands in y-Richtung deutlich geringer ist als in die entgegengesetzte negative y-Richtung. Vergleichbare Eigenschaften weisen auch Bänder 4 auf, deren Querschnitte einem der in Fig . 8 schematisch angedeuteten Querschnitten entsprechen. Dabei sind die in Fig. 8 dargestellten Querschnitte nur exemplarisch und nicht als abschließende Aufzählung geeigneter In addition, the screw 7 in cooperation with the attachment lug 12 is a punctual mechanical connection between the bands 4, over which the bands 4 abut each other as provided by the invention. The attachment lug 12 holds the band ends in a nem certain distance from each other, so that in a section through the bands 4 along the line II in Fig. 1, the view of FIG. 5 results. It can also be seen from this figure that each band 4 in the extended state has an arcuate cross section transverse to its extension direction, as can be seen from FIG. 7, which shows a sectional view through the support strut 2 along the line II in FIG. 1 shows. As a result of this arcuate cross-section, each individual band 4 has a significantly lower buckling stiffness in the y direction, which extends transversely to the direction of extension, than in the x direction, which also extends transversely to the extension direction. Furthermore, the arcuate cross-section has the consequence that the buckling stiffness of the indicated in Figure 5 with 4.1 bands in the y-direction is significantly less than in the opposite negative y-direction. Comparable properties also have bands 4, whose cross sections one of the in Fig. 8 correspond schematically indicated cross sections. In this case, the cross sections shown in Fig. 8 are only exemplary and not suitable as a final list
Querschnittsformen zu verstehen. To understand cross-sectional shapes.
Fig. 3a zeigt eine alternative Ausführung einer Tragstrebe 2 einer erfindungsgemäßen Leuchte 100. In dieser alternativen Ausführung sind die bogenförmigen Bänder 4 mit ihren Rücken 9 gegeneinander orientiert, so dass sie sich mit ihren Rücken 9 entlang einer Berührlinie L mechanisch aneinander abstützen, wie dies aus der Schnittdarstellung gemäß Fig. 7 ersichtlich ist, die einen Schnitt entlang der Linie III-III in Fig. 3a zeigt. Dies führt zu einer gegenüber der Ausgestaltung gemäß Fig. 3 nochmals erhöhten Knicksteifigkeit der Tragstrebe 2 insgesamt sowohl in positiver als auch in negativer y-Richtung. Fig. 3a shows an alternative embodiment of a support strut 2 of a lamp 100 according to the invention. In this alternative embodiment, the arcuate bands 4 are oriented with their backs 9 against each other, so that they are mechanically supported with their backs 9 along a line of contact L, as is apparent from the sectional view of FIG. 7 can be seen, which shows a section along the line III-III in Fig. 3a. This leads to a comparison with the embodiment of FIG. 3 again increased buckling resistance of the support strut 2 in total in both the positive and in the negative y-direction.
Aus der Ausgestaltung der Bänder 4 gemäß Fig . 5 resultiert eine mechanisch hoch belastbare Variante der Leuchtstrebe 2. Bei der Überführung der Bänder 4 in die Querschnittsform gemäß Fig. 5 wird auf der Innenfläche 9 der Bänder 4 eine größere Spannung in Querrichtung, also senkrecht zum dargestellten Querschnitt, und eine Längung auf der Außenfläche 8 erzeugt. Die Spannungen in Längsrichtung werden ausgeglichen und sind im Wesentlichen identisch, so dass die Bänder 4 einen geradlinigen Längsverlauf aufweisen und so den in Fig. 1 und Fig. 2 dargestellten ausgefahrenen Teil der Tragstrebe 2 bilden. Der in Fig. 5 dargestellte bogenförmige Querschnitt der Bänder 4 (oder auch ein Querschnitt gemäß Fig. 8) führt zu einer sehr guten Knicksteifigkeit der gesamten Tragstrebe 2. Des Weiteren ist in der Ausführungsform gemäß Fig. 7. die Stabilität der Tragstrebe 2 nochmals dadurch erhöht, dass sich die Bänder 4 mit ihren Außenflächen 8 berühren und dadurch zusätzlich entlang einer ausgedehnten Berührlinie gegenseitig mechanisch abstützen. From the configuration of the bands 4 according to FIG. 5 results in a mechanically highly resilient variant of the luminous strut 2. When transferring the bands 4 in the cross-sectional shape of FIG. 5 is on the inner surface 9 of the bands 4, a larger voltage in the transverse direction, ie perpendicular to the illustrated cross-section, and an elongation on the outer surface 8 generated. The stresses in the longitudinal direction are compensated and are substantially identical, so that the bands 4 have a straight longitudinal course and thus form the extended part of the support strut 2 illustrated in FIGS. 1 and 2. The illustrated in Fig. 5 arcuate cross section of the bands 4 (or a cross section of FIG. 8) leads to a very good buckling stiffness of the entire support strut 2. Furthermore, in the embodiment according to FIG. 7, the stability of the support strut 2 is further increased by the fact that the bands 4 touch with their outer surfaces 8 and thereby additionally mechanically support one another along an extended contact line.
Im aufgerollten Zustand sind die Bänder 4 im Allgemeinen im Querschnitt geradlinig geformt (siehe Fig. 6). Dies ist aber optional, grundsätzlich ist eine Veränderung des Querschnitts der Bänder 4 beim Aufrollen nicht zwingend erforderlich. In diesem flachen Zustand ist auf der Innenfläche 9 des Bandes 4 eine größere Spannung erzeugt als auf der Außenfläche 8. Senkrecht zum dargestellten Querschnitt sind jedoch die Spannungen auf der Innenfläche 9 und auf der Außenfläche 8 im Wesentlichen gleich, so dass die gerade Form eingenommen wird. When rolled up, the bands 4 are generally rectilinear in cross section (see Fig. 6). However, this is optional, in principle a change in the cross section of the bands 4 when rolling up is not absolutely necessary. In this flat state, a greater stress is generated on the inner surface 9 of the band 4 than on the outer surface 8. However, perpendicular to the illustrated cross-section, the stresses on the inner surface 9 and on the outer surface 8 are substantially equal, so that the straight shape is assumed ,
Jedem Band 4 ist eine eigene Aufrollmechanik 15 zugeordnet, wie aus der Aufsicht gemäß Fig. 2 ersichtlich ist. Dabei ist jede Aufrollmechanik 15 in der Art ausgebildet, wie sie aus dem Stand der Technik von aufrollbaren Metallmaßbändern bekannt ist, die bei Nichtgebrauch z.B. mittels Federkraft in ein Gehäuse eingezogen und dort aufgerollt werden können. Each band 4 is associated with its own Aufrollmechanik 15, as shown in the plan view of FIG. 2 can be seen. Each roll-up mechanism 15 is formed in the manner known in the art from roll-up metal tapes which, when not in use, are e.g. be pulled by spring force into a housing and rolled up there.
Eine Möglichkeit die Funktionalität der Leuchte zu erhöhen, besteht darin, die Tragstrebe 2 gegen die Horizontale schwenkbar auszubilden. Hierzu ist im One way to increase the functionality of the lamp, is to form the support strut 2 pivotally against the horizontal. This is in the
Leuchtensockel 1 eine Schwenkeinrichtung 13 angeordnet, auf der die beiden Aufrollmechaniken 15 der beiden Bänder 4 gemeinschaftlich gelagert sind, so dass die Bänder 4 in ihrer gestreckten Stellung gemeinschaftlich um eine horizontale Drehachse P verschwenkt werden können. Bevorzugt ist die Schwenkeinrichtung 13 dabei selbsthemmend ausgebildet, so dass die Tragstrebe 2 unabhängig von ihrer Auszuglänge in jeder vom Benutzer gewünschten Winkelstellung festgehalten wird. Die Schwenkeinrichtung ist dabei aus den Figuren 1, 2 und 4 ersichtlich. Lamp base 1, a pivoting device 13 is arranged, on which the two Aufrollmechaniken 15 of the two bands 4 are jointly stored, so that the bands 4 can be pivoted jointly in its extended position about a horizontal axis of rotation P. Preferably, the pivoting device 13 is designed to be self-locking, so that the support strut 2 is held regardless of its extension length in each angle position desired by the user. The pivoting device is shown in FIGS. 1, 2 and 4.
Jede Aufrollmechanik 15 umfasst ihrerseits eine drehbar gelagerte Welle 10, auf der jeweils ein Band 4 aufgerollt werden kann, wie aus Fig. 4 ersichtlich ist. Dabei ist jedes Band 4 für sich gegen seine Auszugrichtung mittels einer an der jeweiligen Welle 10 angreifenden Feder (nicht dargestellt) mechanisch vorgespannt. Zugleich ist jede Aufrollmechanik 15 selbsthemmend ausgebildet, dergestalt dass jedes Band 4 in jedem vom Benutzer gewünschten Auszugzustand mechanisch arretiert ist. Weiterhin umfasst jede Aufrollmechanik 15 jeweils einen Umformbereich 5, wie in Fig. 4 schematisch angedeutet. Der Umformbereich 5 sorgt beim Herausziehen der Tragstrebe 2 für das Umformen der Bänder 4 von dem geradlinigen Querschnitt gemäß Fig. 6 in einen bogenförmigen Querschnitt z. B. gemäß Fig. 5 oder 7 und beim Hereinfahren der Tragstrebe 2 für das Umformen der Bänder 4 von einem bogenförmigen in einen geradlinigen Querschnitt. Each Aufrollmechanik 15 in turn comprises a rotatably mounted shaft 10, on each of which a tape 4 can be rolled up, as shown in FIG. 4 can be seen. In this case, each band 4 is mechanically biased against its extension direction by means of a force acting on the respective shaft 10 spring (not shown). At the same time, each roll-up mechanism 15 is designed to be self-locking, such that each band 4 is mechanically locked in any extension state desired by the user. Furthermore, each Aufrollmechanik 15 each comprise a forming region 5, as indicated schematically in Fig. 4. When the support strut 2 is withdrawn, the forming area 5 ensures the forming of the bands 4 from the straight-line cross section according to FIG. 6 into an arcuate cross section z. As shown in FIG. 5 or 7 and when driving in the support strut 2 for the forming of the bands 4 of an arcuate in a rectilinear cross-section.
Weiterhin sind beide Aufrollmechaniken 15, die in einer gemeinsamen Ebene nebeneinander liegend angeordnet sind, gemeinschaftlich auf einer Schwenkeinrichtung 13 befestigt, deren Funktionalität vorstehend bereits beschrieben wurde. Diese Schwenkeinrichtung 13 ist unter Ausbildung der Drehachse P drehbar auf einer Welle 11 gelagert, die ihrerseits drehfest mit dem Gehäuse des Furthermore, both Aufrollmechaniken 15, which are arranged in a common plane next to each other, jointly mounted on a pivoting device 13, whose functionality has already been described above. This pivoting device 13 is rotatably mounted on a shaft 11 with the formation of the rotation axis P, which in turn rotatably connected to the housing of the
Leuchtensockels 1 verbunden ist. Light socket 1 is connected.
Im Folgenden wird die Funktionsweise der oben beschriebenen Leuchte kurz erläutert: The operation of the luminaire described above is briefly explained below:
Die Tragstrebe 2 ist zumindest was ihren aus dem Leuchtensockel 1 ausgefahrenen Teil angeht, in ihrer Länge veränderbar ausgestaltet. Durch Aufbringen einer Handkraft in Längsrichtung der Trag strebe 2 lässt sich diese entweder in den Leuchtensockel 1 hinein schieben, so dass sich die unteren Enden der Bänder 4 um die Welle 10, die drehbar im Leuchtensockel 1 gelagert ist, aufrollen. Zudem lässt sich die Tragstrebe 2 zur Verlängerung herausziehen. Dies wird durch den Doppelpfeil in Fig. 1 dargestellt. Der Winkel der Tragstrebe 2 gegen die Horizontale ist vom Benutzer veränderbar, wie in Fig. 1 durch den gestrichelten Doppelpfeil angedeutet ist. The support strut 2 is at least as far as its part extended from the lamp base 1 part, designed to be variable in length. By applying a manual force in the longitudinal direction of the support strut 2 can be this either slide into the lamp base 1, so that the lower ends of the bands 4 about the shaft 10, which is rotatably mounted in the lamp base 1, roll up. In addition, the support strut 2 can be pulled out to extend. This is represented by the double arrow in FIG. The angle of the support strut 2 against the horizontal is variable by the user, as indicated in Fig. 1 by the dashed double arrow.
Fig. 9 zeigt schließlich verschiedene alternative Bandkonfigurationen von zwei und mehr Bändern 4 mit bogenförmigem Querschnitt zur Ausbildung der Tragstrebe 2. Unter anderem ist aus dieser Figur ersichtlich, dass die im vorstehenden Ausführungsbeispiel gezeigte Bandkonfiguration„Rücken-an-Rücken" nicht verpflichtend ist. Auch kann der Figur entnommen werden, wie die„Rücken-an- Rücken"-Konfiguration der Fig . 5 weiterentwickelt werden kann für Konfigurationen mit drei bzw. vier Bändern 4, in der die Bänder 4 wiederum zumindest an einem Punkt mechanisch mit zumindest einem benachbarten Band 4 verbunden sind . Finally, Fig. 9 shows various alternative band configurations of two and more bands 4 of arcuate cross section to form the support strut 2. Among other things, it can be seen from this figure that the band configuration "back-to-back" shown in the previous embodiment is not mandatory can be taken from the figure, as the "back-to-back" configuration of FIG. 5 can be further developed for configurations with three or four bands 4, in which the bands 4 are in turn at least at one point mechanically connected to at least one adjacent band 4.
