- the cover is made of plastic and the support of metal.
- the edge of the light emission surface has a uniform appearance on all sides; there are no end caps required, because due to the lateral wall portion of the carrier does not have to extend to the light emitting surface. Due to the light-tight layer on the lateral wall area, the edge can be made to appear particularly clear and precise. It can almost cause a "frameless" appearing light delivery surface.
- the layer consists of a metal and the cover for example of PMMA (polymethyl methacrylate).
- PMMA polymethyl methacrylate
- the layer is formed by a film and / or by a lacquer.
- the layer can be made very thin and thus the edge of the light emitting surface defined particularly sharp, so to speak, like a line.

- a light source 5 is supported on the carrier 3.
- the light source 5 may in particular be a plurality of LEDs, which is preferably arranged in a matrix-like manner on a circuit board, which in turn is supported on the carrier 3, in particular with good heat conductivity.
- the luminaire is designed such that a light emitted by the light source 5 passes through the light emission surface 21 and is emitted into an exterior space of the luminaire.
- the light source 5 preferably represents a light source 5 for emitting light of the lamp.
- the layer 4 is designed so that it is reflective, in particular on its inner side, ie on the side facing a center of the cover 2.
- a particularly good efficiency can be achieved for the lamp.
- the carrier 3 is preferably designed so that it forms a surface region of the lamp. In particular, it can be designed as a heat sink for the light source 5.

Description
Die Erfindung betrifft eine längliche Leuchte.The invention relates to an elongated lamp.
Die Anmelderin vertreibt eine längliche Leuchte unter der Bezeichnung SLOTLIGHT II. Diese Leuchte umfasst ein profilartiges, im Querschnitt in erster Näherung U-förmiges, Kanalelement aus Aluminium sowie eine längliche, lichtdurchlässige Kunststoffabdeckung, die in das Kanalelement eingeschnappt ist und durch die eine plane, lichtabgebende Fläche der Leuchte gebildet ist. An den beiden Längs-Enden der Leuchte ist jeweils eine Endkappe aufgesetzt. Bei Temperaturänderungen verändern sich die Längserstreckungen des Kanalelements aus Aluminium einerseits und der Kunststoffabdeckung andererseits in unterschiedlichem Ausmaß. Die Endkappen dienen dazu, diese unterschiedlichen Längsveränderungen zu kaschieren. Die Endkappen führen allerdings auch dazu, dass das äußere Erscheinungsbild der Leuchte bei Betrachtung auf die lichtabgebende Fläche randseitig uneinheitlich ist. Die Längsränder der lichtabgebenden Fläche erscheinen anders als die stirnseitigen Ränder bei den Endkappen.The Applicant sells an elongated luminaire under the name SLOTLIGHT II. This luminaire comprises a profile-like, in cross-section in a first approximation U-shaped, aluminum channel element and an elongated, translucent plastic cover which is snapped into the channel element and through which a plane, light-emitting Surface of the lamp is formed. At the two longitudinal ends of the lamp an end cap is placed in each case. With temperature changes, the longitudinal extent of the channel element made of aluminum on the one hand and the plastic cover on the other hand vary to different degrees. The end caps serve to conceal these different longitudinal changes. However, the end caps also lead to the appearance of the luminaire when viewed on the light-emitting surface edge is uneven. The longitudinal edges of the light-emitting surface appear differently than the front edges of the end caps.

Der Erfindung liegt die Aufgabe zugrunde, eine längliche Leuchte anzugeben, die ein besonders gleichmäßiges äußeres Erscheinungsbild ermöglicht. Insbesondere soll die Leuchte ermöglichen, dass bei Betrachtung der lichtabgebenden Fläche der Rand dieser Fläche umlaufend besonders gleichmäßig erscheint.The invention has for its object to provide an elongated lamp that allows a particularly uniform appearance. In particular, the luminaire is intended to make it possible that, when viewing the light-emitting surface, the edge of this surface appears to be particularly uniform all around.
Diese Aufgabe wird gemäß der Erfindung mit dem in dem unabhängigen Anspruch genannten Gegenstand gelöst. Besondere Ausführungsformen der Erfindung sind in den abhängigen Ansprüchen angegeben.This object is achieved according to the invention with the object mentioned in the independent claim. Particular embodiments of the invention are indicated in the dependent claims.
Gemäß der Erfindung ist eine Leuchte vorgesehen, die eine längliche Abdeckung mit einer, in einer Ebene verlaufenden, planen Lichtabgabefläche aufweist, sowie einen länglichen Träger, wobei die Abdeckung an dem Träger gehaltert angeordnet ist. Die Abdeckung weist dabei einen seitlichen Wandbereich auf, der sich in geschlossen umlaufender Form unmittelbar an die Lichtabgabefläche anschließt. Auf dem seitlichen Wandbereich ist dabei eine lichtdichte Schicht aufgebracht. Die Abdeckung besteht aus Kunststoff und der Träger aus Metall.According to the invention, there is provided a luminaire having an elongated cover with a planar light emission surface extending in a plane, and an elongated support, the cover being mounted on the support. The cover has a lateral wall area, which is closed circumferential shape immediately adjoins the light emitting surface. In this case, a light-tight layer is applied to the lateral wall region. The cover is made of plastic and the support of metal.
Durch den umlaufend gestalteten seitlichen Wandbereich lässt sich erzielen, dass der Rand der Lichtabgabefläche allseits ein einheitliches Erscheinungsbild aufweist; es sind keine Endkappen erforderlich, da sich aufgrund des seitlichen Wandbereichs der Träger nicht bis zu der Lichtabgabefläche hin erstrecken muss. Durch die lichtdichte Schicht auf dem seitlichen Wandbereich lässt sich der Rand dabei besonders klar und präzise erscheinend gestalten. Es lässt sich quasi eine "rahmenlos" erscheinende Lichtabgabefläche bewirken.Due to the circumferentially designed lateral wall area, it can be achieved that the edge of the light emission surface has a uniform appearance on all sides; there are no end caps required, because due to the lateral wall portion of the carrier does not have to extend to the light emitting surface. Due to the light-tight layer on the lateral wall area, the edge can be made to appear particularly clear and precise. It can almost cause a "frameless" appearing light delivery surface.
Vorzugsweise besteht die Schicht aus einem Metall und die Abdeckung beispielsweise aus PMMA (Polymethylmethacrylat). Durch eine metallene Schicht auf dem seitlichen Wandbereich der Abdeckung lässt sich besonders geeignet eine lichtdichte Oberfläche auf dem seitlichen Wandbereich bilden, insbesondere wenn der seitliche Wandbereich aus Kunststoff besteht.Preferably, the layer consists of a metal and the cover for example of PMMA (polymethyl methacrylate). By means of a metal layer on the lateral wall region of the cover, a light-tight surface on the lateral wall region can be formed in a particularly suitable manner, in particular if the lateral wall region consists of plastic.
Vorzugsweise ist die Schicht durch eine Folie und/oder durch einen Lack gebildet. Hierdurch lässt sich die Schicht besonders dünn gestalten und damit der Rand der Lichtabgabefläche besonders scharf definiert, sozusagen strichartig. Alternativ kann die Schicht durch eine Koextrusion zusammen mit der Abdeckung gebildet sein.Preferably, the layer is formed by a film and / or by a lacquer. As a result, the layer can be made very thin and thus the edge of the light emitting surface defined particularly sharp, so to speak, like a line. Alternatively, the layer may be formed by coextrusion with the cover.
Vorzugsweise ist die Schicht reflektierend gestaltet. Hierdurch lässt sich für die Leuchte ein besonders guter Wirkungsgrad erzielen.Preferably, the layer is designed to be reflective. As a result, a particularly good efficiency can be achieved for the lamp.
Vorzugsweise ist die Abdeckung so geformt, dass der seitliche Wandbereich und die Lichtabgabefläche allseits einen Winkel von 90° einschließen. Hierdurch lässt sich erzielen, dass bei Betrachtung der Leuchte entgegen der Normalen der Lichtabgabefläche lediglich die Lichtabgabefläche sichtbar ist. Hierdurch lässt sich ein besonders hochwertiger Eindruck der Leuchte bewirken.Preferably, the cover is shaped so that the side wall portion and the light emitting surface enclose an angle of 90 ° on all sides. This makes it possible to achieve that, when the luminaire is viewed against the normal of the light emission surface, only the light emission surface is visible. This can cause a particularly high-quality impression of the lamp.
Vorzugsweise ist die Abdeckung so geformt, dass durch die Lichtabgabefläche und den seitlichen Wandbereich eine Quaderform festgelegt ist. Auf diese Weise lässt sich besonders geeignet die Lichtabgabefläche in Form einer geraden Linie gestalten.Preferably, the cover is shaped so that a parallelepiped shape is defined by the light emitting surface and the lateral wall portion. In this way, the light emission surface can be designed in a particularly straight shape in the form of a straight line.
Vorzugsweise ist die Leuchte derart gestaltet, dass der Träger bei einer Betrachtung der Leuchte entgegen der Normalen der Lichtabgabefläche vollständig durch die Abdeckung verdeckt ist. Auch hierdurch lässt sich das äußere Erscheinungsbild der Leuchte vorteilhaft besonders hochwertig wirkend gestalten.Preferably, the lamp is designed such that the carrier is completely covered by the cover when viewing the lamp against the normal of the light emitting surface. This also makes it possible to make the outer appearance of the lamp advantageous particularly high-quality acting.
Erfindungsgemäß ist die Abdeckung an dem Träger gleitend aufgehängt.According to the invention, the cover is slidably suspended on the carrier.
Vorzugsweise ist an dem Träger eine Lichtquelle, insbesondere in Form von LEDs (LED: Licht emittierende Diode) gehaltert, wobei die Leuchte so gestaltet ist, dass ein von der Lichtquelle abgegebenes Licht durch die Lichtabgabefläche hindurchtritt und in einen Außenraum der Leuchte abgegeben wird. Auf diese Weise lässt sich vorteilhaft erzielen, dass das Licht der Lichtquelle gut durchmischt wird, bevor es die Lichtabgabefläche durchsetzt und somit eine besonders homogene Lichtverteilung auf der Lichtabgabefläche bewirkt wird.Preferably, a light source, in particular in the form of LEDs (LED: light emitting diode) is supported on the support, wherein the lamp is designed so that a light emitted from the light source passes through the light emitting surface and is discharged into an outer space of the lamp. In this way, it can be advantageously achieved that the light of the light source is well mixed before it passes through the light emission surface and thus a particularly homogeneous light distribution is effected on the light emitting surface.
Vorzugsweise bildet der Träger einen Oberflächenbereich der Leuchte, wobei insbesondere der Träger als Kühlkörper für die Lichtquelle der Leuchte ausgestaltet ist.Preferably, the carrier forms a surface region of the lamp, wherein in particular the carrier is designed as a heat sink for the light source of the lamp.
Vorzugsweise ist die Abdeckung im Bereich der Lichtabgabefläche mit einer ersten Schicht und einer zweiten Schicht ausgebildet, wobei die erste Schicht diffus und die zweite Schicht klar gestaltet ist. Dabei sind die erste Schicht und die zweite Schicht herstellungstechnisch vorteilhaft durch eine Koextrusion gebildet.Preferably, the cover is formed in the region of the light emission surface with a first layer and a second layer, the first layer being diffuse and the second layer being clear. In this case, the first layer and the second layer are advantageously formed by coextrusion.

Im Vergleich zum eingangs erwähnten Stand der Technik sind hier also gleichsam die stirnseitigen "Endkappen" als integraler Teil der Abdeckung 2 gestaltet, bzw. solche Endkappen sind durch die beschriebene Gestaltung hinfällig.The
Die Gestaltung kann dabei beispielsweise so sein, dass der Quader bzw. die Abdeckung 2 eine, quer zu der Längsachse L gemessene Breite b aufweist, die zwischen 50 mm und 200 mm, also beispielsweise 100 mm beträgt und eine, senkrecht zu der Längsachse L und zu der Richtung der Breite b stehende Höhe h, die zwischen 30 mm und 150 mm beträgt, also beispielsweise 50 mm oder 60 mm.The design may be, for example, such that the cuboid or the
Beim gezeigten Ausführungsbeispiel ist die Gestaltung weiterhin so, dass sich der Träger 3 auch mit Bezug auf die Breite b weniger weit erstreckt als die Abdeckung 2, so dass sich auch entlang dieser Breitenerstreckung die Abdeckung 2 über den Träger 3 hinaus erstreckt. Auf diese Weise ist die Leuchte so gestaltet, dass der Träger 3 bei einer Betrachtung der Leuchte normal auf die bzw. zur Lichtabgabefläche 21, vollständig durch die Abdeckung 2 verdeckt ist. Hierdurch lässt sich erzielen, dass sich eine temperaturschwankungsbedingte Längenänderung der Abdeckung 2 für einen Betrachter praktisch nicht bemerkbar macht. Vorzugsweise ist der Träger 3 mit Bezug auf die Abdeckung 2 konzentrisch nach innen versetzt.In the embodiment shown, the design is furthermore such that the
Vorzugsweise ist die Leuchte weiterhin so gestaltet, dass bei der genannten Betrachtung der Leuchte auch keine anderweitigen Leuchtenteile neben der Lichtabgabefläche 21 sichtbar sind.Preferably, the lamp is further designed so that in the above-mentioned consideration of the lamp, no other parts of the luminaire next to the
Auf dem seitlichen Wandbereich 22 ist eine lichtdichte Schicht 4 aufgebracht. Dies ist beispielhaft in
Die Schicht 4 kann beispielsweise durch eine Folie gebildet sein, insbesondere durch eine Metall-Folie. Die Folie kann beispielsweise durch eine Folienprägung auf dem seitlichen Wandbereich 22 aufgebracht sein. Alternativ - oder auch ergänzend - kann die Schicht 4 durch einen Lack gebildet sein, insbesondere in Form einer dauerelastischen Lackierung.The
Weiterhin alternativ kann die Schicht 4 zusammen mit der Abdeckung 2 durch eine Koextrusion gebildet sein, so dass auf diese Weise quasi ein dünner, lichtdichter Seitensteg gebildet ist.Furthermore, alternatively, the
Vorzugsweise ist die Schicht 4 derart gestaltet, dass sie eine besonders geringe Stärke aufweist, um so den Rand der Lichtabgabefläche 21 besonders scharf wirkend gestalten zu können.Preferably, the
Vorzugsweise ist an dem Träger 3 eine Lichtquelle 5 gehaltert. Bei der Lichtquelle 5 kann es sich insbesondere um mehrere LEDs handeln, die vorzugsweise matrixartig auf einer Platine angeordnet ist, die wiederum, insbesondere gut wärmeleitend an dem Träger 3 gehaltert ist. Die Leuchte ist dabei so gestaltet, das ein von der Lichtquelle 5 abgegebenes Licht durch die Lichtabgabefläche 21 hindurchtritt und in einen Außenraum der Leuchte abgegeben wird. Mit anderen Worten stellt die Lichtquelle 5 vorzugsweise eine Lichtquelle 5 zur Lichtabgabe der Leuchte dar.Preferably, a
Vorzugsweise ist die Schicht 4 so gestaltet, dass sie reflektierend ist, insbesondere auf ihrer Innenseite, also auf derjenigen Seite, die zu einem Mittelpunkt der Abdeckung 2 hin weist. Hierdurch lässt sich für die Leuchte ein besonders guter Wirkungsgrad erzielen.Preferably, the
Der Träger 3 ist vorzugsweise so gestaltet, das er einen Oberflächenbereich der Leuchte bildet. Insbesondere kann er als Kühlkörper für die Lichtquelle 5 ausgestaltet sein. Die Abdeckung 2 ist an dem Träger gleitend aufgehängt, wie andeutungsweise in
Die Form der Abdeckung 2 kann dementsprechend insgesamt einen länglichen Quader beschreiben, wobei eine der vier Längsseiten, hier die nach oben weisende Längsseite, eine insbesondere rechteckige Öffnung aufweist, die zur Aufhängung an dem Träger 3 ausgestaltet ist.The shape of the
An dem Träger 3 kann außerdem wenigstens ein weiteres Leuchtenbauteil, beispielsweise ein Betriebsgerät 6 zum Betrieb der Lichtquelle 5 gehaltert sein. Auch ein Aufhängeelement zur Aufhängung der Leuchte, beispielsweise an einer Decke kann an dem Träger 3 vorgesehen bzw. ausgebildet sein.At least one further lighting component, for example an
Eine besonders geeignete Lichtverteilung auf der Lichtabgabefläche 21 lässt sich erzielen, wenn die Abdeckung 2 im Bereich der Lichtabgabefläche 21 mit einer ersten Schicht 211 und einer zweiten Schicht 212 ausgebildet ist, wobei die erste Schicht 211 diffus und die zweite Schicht 212 klar gestaltet ist. Insbesondere kann dabei die diffuse bzw. erste Schicht 211 mit Bezug auf den Mittelpunkt der Abdeckung 2 eine innere Schicht bilden und die klare bzw. zweite Schicht 212 eine äußere Schicht. Herstellungstechnisch vorteilhaft können hierzu die erste Schicht 211 und die zweite Schicht 212 durch eine Koextrusion gebildet sein. Der seitliche Wandbereich 22 bzw. die restliche Abdeckung 2 kann dieselben Materialeigenschaften bzw. optischen Eigenschaften aufweisen wie die erste Schicht 211. Alternativ können die beiden genannten Schichten 211, 212 auch getrennt voneinander ausgebildet sein.A particularly suitable light distribution on the light-emitting
Die Leuchte eignet sich beispielsweise dafür, mit einer umlaufenden Schattenfuge in eine Decke eingebaut zu werden. Die Schattenfuge kann dabei sehr schmal sein, beispielsweise lediglich 13 mm.The luminaire is suitable, for example, for being installed in a ceiling with a circumferential shadow gap. The shadow gap can be very narrow, for example, only 13 mm.
Die Lichtabgabefläche 21 lässt sich also sehr exakt gestalten. Die Leuchte ermöglicht sozusagen eine rahmenlose Anmutung der Lichtabgabefläche 21.The light-emitting
