Description

Die vorliegende Erfindung betrifft ein Lichtelement eines Möbelsystems, insbesondere eines Möbelsystems für eine Küche.The present invention relates to a light element of a furniture system, in particular a furniture system for a kitchen.

Die Beleuchtung eines Möbelsystems oder eines Möbels bzw. des Anstrahlen von Teilen eines Möbelsystems findet immer weiter Verbreitung. Dadurch wird es dem Gestalter eines Möbelsystems oder eines Möbels ermöglicht, einzelne Aspekte des Möbels hervorzuheben und insgesamt ein besseres Raumklima durch das angestrahlte Möbel zu erzeugen.The lighting of a furniture system or a piece of furniture or the lighting of parts of a furniture system is becoming more widespread. This allows the designer of a furniture system or a piece of furniture to emphasize individual aspects of the piece of furniture and, overall, to create a better indoor climate by the illuminated furniture.

Obwohl die Verbreitung von LED-Lichtleisten dazu geführt hat, Möbel mit platzsparenden Elementen anzuleuchten, behindern diese Lichtelemente oftmals den optischen Eindruck des Möbels. Auch sorgt die Anbindung des Lichtelementes an einen elektrischen Stromkreis oftmals für eine wenig anregende Betrachtung.Although the spread of LED light strips has led to illuminate furniture with space-saving elements, these lighting elements often obstruct the visual impression of the furniture. Also, the connection of the light element to an electrical circuit often provides for a little stimulating consideration.

Es ist das Ziel der vorliegenden Erfindung ein Lichtelement für ein Möbelsystem vorzusehen, dass ein flächiges Element des Möbelsystems ohne die vorstehend aufgeführten Beeinträchtigungen anstrahlt.It is the object of the present invention to provide a lighting element for a furniture system that illuminates a planar element of the furniture system without the above-mentioned impairments.

Dies gelingt mit einem Lichtelement eines Möbelsystems, dass die Merkmale des Anspruch 1 besitzt. Demnach umfasst das Lichtelement eine Lichterzeugungseinheit zum Abgeben von Licht und eine Lichtumlenkvorrichtung, die von der Lichterzeugungseinheit abgegebenes Licht umlenkt, wobei das Möbelsystem ein flächiges Wandpaneel und ein Befestigungselement für das Wandpaneel umfasst. Das Lichtelement ist dadurch gekennzeichnet, dass die Lichterzeugungseinheit auf der einen Seite des Wandpaneels angeordnet ist und die Lichtumlenkvorrichtung auf der anderen Seite des Wandpaneels angeordnet ist. Somit trennt das Wandpaneel einen Bereich, indem das Licht umgelenkt wird und einen Bereich indem das Licht durch die Lichterzeugungseinheit erzeugt wird.This is achieved with a light element of a furniture system that has the features of claim 1. Accordingly, the light element comprises a light generating unit for emitting light and a light deflection device, which deflects light emitted by the light generating unit, the furniture system comprising a planar wall panel and a fastening element for the wall panel. The light element is characterized in that the light generation unit is arranged on one side of the wall panel and the light deflection device is arranged on the other side of the wall panel. Thus, the wall panel separates an area by redirecting the light and an area where the light is generated by the light generating unit.

Dadurch ist es möglich, dass die von einem Betrachter wahrgenommene Seite eines Wandpaneels nicht mit den bisherigen Einschränkungen einer LED-Lichtleiste zu kämpfen hat.This makes it possible that the perceived by a viewer side of a wall panel does not have to struggle with the previous limitations of a LED light bar.

Vorzugsweise ist die Lichtumlenkvorrichtung ein flächiges Element, das in seinem zur Längsrichtung quer verlaufenden Querschnitt einen gebogenen Abschnitt aufweist, vorzugsweise einen kreiselementförmigen Abschnitt aufweist. Durch Anstrahlen dieses flächigen Elementes mit dem gebogenen Abschnitt wird das Licht auf eine für das menschliche Auge besonders angenehme Weise umgelenkt. Von Vorteil ist, wenn der gebogene Abschnitt in seinem Querschnitt in etwa einem Winkel-bereich von 70 bis 100 Grad, vorzugsweise 75 bis 95 Grad und bevorzugter Weise ca. 90 Grad aufweist.Preferably, the light deflection device is a planar element, which has a bent portion in its cross-section extending transversely to the longitudinal direction, preferably has a circular-segment-shaped section. By illuminating this sheet-like element with the bent portion, the light is deflected in a way that is particularly pleasant for the human eye. It is advantageous if the curved portion in its cross section in an approximately angular range of 70 to 100 degrees, preferably 75 to 95 degrees, and more preferably about 90 degrees.

Gemäß einer Fortbildung der Erfindung erfolgt eine Lichtabgabe der Lichterzeugungseinheit in einem Zwischenraum von übereinander angeordneten Wandpanee-len. Das Möbelsystem kann demnach eine Vielzahl von vertikal übereinander angeordneten Wandpaneelen umfassen, wobei in dem Randbereich zu einem benachbarten Wandpaneel ein Zwischenraum vorgesehen ist, durch den sich ein Be-festigungselement von der einen flächigen Seite zu der anderen flächigen Seite der Wandpaneele erstreckt. Dieser Zwischenraum wird auch genutzt, um das eine flächige Seite des Wandpaneels zu bestrahlende Licht abzugeben.According to a development of the invention, a light emission of the light generating unit takes place in a gap of stacked wall panels. The furniture system may therefore comprise a plurality of vertically stacked wall panels, wherein in the edge region to an adjacent wall panel, a gap is provided through which a Be-fastening element from the one flat side to the other flat side of the Wall panels extends. This space is also used to deliver the one flat side of the wall panel to be irradiated light.

Gemäß einer optionalen Modifikation der Erfindung erfolgt die Lichtabgabe der Lichterzeugungseinheit in einem Bereich, der in etwa der Mitte der Dicke eines Wandpaneels entspricht.According to an optional modification of the invention, the light emission of the light-generating unit takes place in a region which corresponds approximately to the middle of the thickness of a wall panel.

Gemäß einer bevorzugten Ausführung der Erfindung ist die Lichtumlenkvorrichtung eine Folie, die an eine Längskante mit einem Anschlagabschnitt eines aus der Ebene des Wandpaneels hervortretenden Befestigungsmittels zusammenwirkt. Dabei wirkt die Folie mit einem Abschnitt des Befestigungselementes zusammen, der zu der Seite des Wandpaneels hervortritt, welcher mit Licht bestrahlt werden soll.According to a preferred embodiment of the invention, the Lichtumlenkvorrichtung is a film which cooperates with a longitudinal edge of a stop portion of a protruding from the plane of the wall panel fastener. In this case, the film cooperates with a portion of the fastener, which emerges to the side of the wall panel, which is to be irradiated with light.

Gemäß einer weiteren Fortbildung der Erfindung ist die Lichtumlenkvorrichtung eine Folie, die an einer ihrer Längskanten in eine Nut oder eine Abkantung des aus der Ebene des Wandpaneels hervortretenden Befestigungsmittels eingefügt ist.According to a further development of the invention, the light deflection device is a film which is inserted at one of its longitudinal edges into a groove or a fold of the protruding from the plane of the wall panel fastener.

Vorzugsweise weist die Nut oder die Abkantung, in die die Lichtumlenkvorrichtung mit einer ihrer Längskanten aufgenommen ist, einen zur Ebene des Wandpaneels senkrechten Abschnitt auf.Preferably, the groove or the fold, in which the Lichtumlenkvorrichtung is taken with one of its longitudinal edges, on a plane perpendicular to the wall panel section.

Vorzugsweise erstreckt sich das Befestigungselement mit seinem aus der Ebene des Wandpaneels hervortretendem Abschnitt über einen Teil oder die gesamte Länge des Wandpaneels.Preferably, the fastener extends with its protruding from the plane of the wall panel section over a part or the entire length of the wall panel.

Gemäß einer Fortbildung der Erfindung weist das Befestigungselement in Querschnitt einen T-förmigen oder einen ┌-förmigen Abschnitt auf, der sich aus der Ebene des Wandpaneels zu der von der Lichterzeugungseinheit abgewandten Seite erstreckt. Dabei umfasst das Befestigungselement vorzugsweise nur Abschnitte, die entweder senkrecht oder parallel zu der durch das Wandpaneel gebildeten Ebene sind.According to a development of the invention, the fastening element in cross-section on a T-shaped or a ┌-shaped portion which extends from the plane of the wall panel to the side remote from the light generating unit side. In this case, the fastening element preferably only comprises sections which are either perpendicular or parallel to the plane formed by the wall panel.

Weiter vorzugsweise weist der zur Ebene des Wandpaneels parallele Abschnitt des Befestigungselementes an seinem distalen Ende eine zum Wandpaneel hingewandte, senkrecht zum Wandpaneel verlaufende Erhebung auf, vorzugsweise eine nasenförmige Ausbuchtung, mit der die Umlenkvorrichtung in Kontakt steht.Further preferably, the parallel to the plane of the wall panel portion of the fastening element at its distal end to the Wandpaneel wandewand, perpendicular to the wall panel extending survey, preferably a nose-shaped bulge, with which the deflection device is in contact.

Dabei kann vorgesehen sein, dass die Lichtumlenkvorrichtung eine Folie ist, die sowohl mit der senkrecht zum Wandpaneel verlaufenden Erhebung an den distalen Ende des parallelen Abschnitts des Befestigungselementes als auch mit einem senkrecht zum Wandpaneel verlaufenden Abschnitt des Befestigungselementes in Kontakt ist, der nicht aus der Ebene des Wandpaneels hervorsteht.It can be provided that the Lichtumlenkvorrichtung is a film which is in contact with both the perpendicular to the wall panel extending survey to the distal end of the parallel portion of the fastener and with a perpendicular to the wall panel extending portion of the fastener, which is not out of the plane protruding from the wall panel.

Gemäß einer optionalen Modifikation der Erfindung umfasst das Lichtelement einen Lichtleiter, der im Lichtpfad zwischen Lichterzeugungseinheit und Lichtumlenkvorrichtung einfügt, wobei sich der Lichtleiter vorzugsweise direkt an die Lichterzeugungseinheit anschließt.According to an optional modification of the invention, the light element comprises a light guide which inserts in the light path between the light generating unit and the light deflection device, wherein the light guide preferably connects directly to the light generating unit.

Dabei kann vorgesehen sein, dass der Lichtleiter das Licht um ca. 90 Grad umlenkt, um eine Lichtauslassrichtung der Lichterzeugungseinheit in einer Ebene des Wandpaneels zu ermöglichen.It can be provided that the light guide deflects the light by approximately 90 degrees in order to allow a light outlet direction of the light generating unit in a plane of the wall panel.

Ferner kann vorgesehen sein, dass der Lichtleiter das Licht für ein Wandpaneel im Mittenbereich der Dicke des Wandpaneels abstrahlt.Furthermore, it can be provided that the light guide radiates the light for a wall panel in the central region of the thickness of the wall panel.

Gemäß einer weiteren bevorzugten Ausführungsform strahlt der Lichtleiter das Licht in einem Bereich ab, in dem eine Folie der Lichtumlenkvorrichtung bereits angeordnet ist.According to a further preferred embodiment, the light guide radiates the light in a region in which a film of the light deflection device is already arranged.

Fig. 1 zeigt eine vertikale Wand 6, an der ein Befestigungselement 5 zum Befestigen eines Wandpaneels 4 angeordnet ist. Ferner erkennt man ein Lichtelement 1 zum Bestrahlen einer flächigen Seite des Wandpaneels 4. Diese Seite ist typischerweise die von der Wand 6 abgewandte Seite des Wandpaneels 4. Zudem erkennt man, dass oberhalb einer Längskante des Wandpaneels 4 das Lichtelement 1 angeordnet ist und sich zu beiden Seiten des Wandpaneels 4 erstreckt. Die Lichterzeugungseinheit 2 gibt Licht ab, und eine Lichtumlenkvorrichtung 3 lenkt dieses Licht um. Die Umlenkung des Lichts passiert dabei auch auf einer Seite des Wandpaneels 4, die zu der Seite der Anordnungsposition der Lichterzeugungseinheit 2 abgewandt ist. Dadurch ist es möglich, eine relativ einfache und kompakte Lichterzeugungseinheit zu verwenden, ohne auf den optischen Gesamteindruck, der von der bestrahlten Seite des Wandpaneels 4 dominiert wird, zu achten. Dies verbilligt die Erzeugung und die Herstellung der Lichterzeugungseinheit wodurch auch auf robuste und solche Bauteile zurückgegriffen werden kann, die bereits ihre jahrelange Zuverlässigkeit unter Beweis gestellt haben. Fig. 1 shows a vertical wall 6, on which a fastening element 5 is arranged for fixing a wall panel 4. Furthermore, one recognizes a light element 1 for irradiating a flat side of the wall panel 4. This side is typically the side facing away from the wall 6 of the wall panel 4. In addition, it can be seen that above a longitudinal edge of the wall panel 4, the light element 1 is arranged and to both Pages of the wall panel 4 extends. The light generating unit 2 emits light, and a light deflecting device 3 redirects this light. The deflection of the light also occurs on one side of the wall panel 4, which faces away from the side of the arrangement position of the light generating unit 2. This makes it possible to use a relatively simple and compact light-generating unit without paying attention to the overall visual impression dominated by the irradiated side of the wall panel 4. This reduces the cost of producing and manufacturing the light generating unit, which also makes it possible to rely on robust components and components that have already proven their reliability over many years.

Fig. 2 zeigt eine Detailansicht einer Umsetzung der vorliegenden Erfindung. An der Wand 6, die sich vertikal zu einer Bodenebene erstreckt, ist ein Befestigungselement 5 angeordnet. Dieses ist typischerweise mit der Wand 6 durch eine Schraube oder ein Klebstoff verbunden. Man erkennt, dass sich das Befestigungselement 5 durch einen Zwischenraum von zwei vertikal übereinander angeordneten Wandpaneelen 4 hindurch erstreckt und einen Abschnitt 51 aufweist, der aus der durch das Wandpaneel 4 gebildeten Ebene hervortritt. Darüber hinaus umfasst das Befestigungselement einen zu der Ebene des Wandpaneels 4 parallelen Abschnitt 52, der an dem Abschnitt 51 angeordnet ist. Der Abschnitt 52 liegt also in einer Ebene, die parallel zu der durch das Wandpaneel erzeugten Ebene ist, wobei die Ebenen jedoch einen Abstand zueinander aufweisen. Zudem ist der Abschnitt 52 auf der Seite des Wandpaneels 4 angeordnet, die mit einem Licht bestrahlt werden soll. Die Lichterzeugungseinheit 2 befindet sich an der Seite des Wandpaneels 4, bei der keine Bestrahlung mit Licht erfolgt. Fig. 2 shows a detailed view of an implementation of the present invention. On the wall 6, which extends vertically to a ground plane, a fastening element 5 is arranged. This is typically connected to the wall 6 by a screw or glue. It can be seen that the fastening element 5 extends through a gap of two vertically stacked wall panels 4 and has a portion 51, which protrudes from the plane formed by the wall panel 4 level. In addition, the fastening element comprises a parallel to the plane of the wall panel 4 section 52, which is arranged on the portion 51. Thus, the portion 52 lies in a plane which is parallel to the plane created by the wall panel, but the planes are at a distance from each other. In addition, the portion 52 is disposed on the side of the wall panel 4 to be irradiated with a light. The Light generating unit 2 is located on the side of the wall panel 4, in which no irradiation with light takes place.

Über einen Lichtleiter 6 wird das von der Lichterzeugungseinheit ausgegebene Licht in einen Zwischenraum der übereinander angeordneten Wandpaneele 4 geleitet. Etwa auf Höhe der Mitte in Dickenrichtung des Wandpaneels 4 wird das Licht von dem Lichtleiter 6 abgegeben. Im weiteren Strahlengang des Lichts trifft dieses dann auf den gekrümmten Bereich der Lichtumlenkvorrichtung 3, welcher das Licht auf die zu beleuchtende flächige Seite des Wandpaneels 4 richtet.Via a light guide 6, the light emitted by the light generating unit light is directed into an intermediate space of the wall panels 4 arranged one above the other. Approximately at the level of the middle in the thickness direction of the wall panel 4, the light is emitted from the light guide 6. In the further beam path of the light, this then hits the curved area of the light deflection device 3, which directs the light onto the planar side of the wall panel 4 to be illuminated.

Das Befestigungsmittel erstreckt sich über einen Teil oder die gesamte Länge einer Längskante eines Wandpaneels 4, sodass auch die Lichtumlenkvorrichtung 3 eine Folie oder ein folienartiges Element darstellen kann, dass über eine gewisse Längsausdehnung verfügt.The fastening means extends over a part or the entire length of a longitudinal edge of a wall panel 4, so that the light deflection device 3 can also be a foil or a foil-like element that has a certain longitudinal extent.

Darüber hinaus erkennt man an den beiden distalen Enden des Abschnitts 52 einen Widerhakenabschnitt bzw. eine nasenförmige Ausbuchtung, die sich im Wesentlichen senkrecht zu der durch das Wandpaneel 4 gebildeten Ebene erstreckt. Eine durch den Widerhakenabschnitt bzw. die nasenförmige Ausbuchtung geschaffene Anschlagfläche wird zum Kontaktieren einer Längskante der Folie der Lichtumlenkvorrichtung 3 verwendet. Durch geschicktes Positionieren der anderen Längskante an dem Befestigungselement 5, vorzugsweise an einem Bereich, der nicht zu der zu beleuchtenden Seite des Wandpaneels 4 heraustritt, wird eine besonders kompakte und einfach zu realisierende Lichtumlenkvorrichtung geschaffen. Ferner erzielt diese Lichtumlenkvorrichtung auch hervorragende optische Beleuchtungsergebnisse des Wandpaneels 4.In addition, it can be seen at the two distal ends of the portion 52 a barb portion or a nose-shaped bulge, which extends substantially perpendicular to the plane formed by the wall panel 4 level. A stop surface provided by the barb portion or the nose-shaped projection is used for contacting a longitudinal edge of the film of the light deflection device 3. By cleverly positioning the other longitudinal edge on the fastening element 5, preferably on an area which does not emerge from the side of the wall panel 4 to be illuminated, a particularly compact and easily implemented light deflection device is provided. Furthermore, this light deflection device also achieves excellent optical illumination results of the wall panel 4.

Falls es erforderlich ist, in dem Raum zwischen Wandpaneel 4 und Wand 6 eine platzsparende Anordnung der Lichterzeugungseinheit 2 vorzusehen, kann der Lichtleiter 6 dazu ausgelegt sein, das Licht in einem Winkel von ca. 90 Grad umzulenken. Die Abstrahlung des Lichts auf die durch eine Folie realisierte Lichtumlenkvorrichtung 3 erfolgt dabei dennoch erst im Zwischenraum der übereinander angeordneten Wandpaneele 4, vorzugsweise in einem Bereich, der mittig in der Dicke der Wandpaneele 4 angeordnet ist.If it is necessary to provide a space-saving arrangement of the light generating unit 2 in the space between the wall panel 4 and the wall 6, the light guide 6 can be designed to deflect the light at an angle of approximately 90 degrees. The radiation of the light on the realized by a foil light deflection device 3 is still carried out only in the space of the superposed Wall panels 4, preferably in a region which is arranged centrally in the thickness of the wall panels 4.

Fig. 3 zeigt eine schematische Draufsicht auf ein mit dem Lichtelement versehenes Möbelsystem. Man erkennt die übereinander angeordneten Wandpaneele 4 und die dazwischen angeordneten Befestigungselemente 5. Die Lampensymbole symbolisieren dabei das Vorhandensein des erfindungsgemäßen Lichtelementes, das die flächige Seite des Wandpaneels 4 mit Licht bestrahlt. Im Hintergrund ist die Wand 6 zu erkennen, an der das Befestigungselement 5 angeordnet ist. Fig. 3 shows a schematic plan view of a provided with the light element furniture system.
