Abstract
Description
Der Gegenstand der Erfindung betrifft eine Leuchte, z.B. eine Deckeneinbau- oder -anbauleuchte, mit einem Gehäuse, in dem ein Reflektor und ein Leuchtmittel angeordnet sind.The subject of the invention relates to a luminaire, e.g. a recessed ceiling or luminaire, with a housing in which a reflector and a light source are arranged.
Reflektoren werden im Stand der Technik üblicherweise aus Aluminium oder einem anderen Material, welches spiegelnd oder matt reflektierend beschichtet ist, gefertigt. Zur Erzielung der gewünschten Lichtlenkung wird die Reflektorfläche, meist in einem Stanzbiegeprozess, in eine gewünschte Form gebracht. Die Reflektoren sind in der Regel für eine Art von Leuchte verwendbar und können nach der Endmontage der Leuchte nicht mehr oder nur mit erheblichem Aufwand ausgetauscht werden. Ferner haben die vorgefertigten Reflektoren den Nachteil, dass sie aufgrund ihrer dreidimensionalen Form bei Lagerung und Transport viel Platz beanspruchen.Reflectors are usually made in the prior art of aluminum or other material which is reflective or matt reflective coated. To achieve the desired light control, the reflector surface is brought into a desired shape, usually in a stamping bending process. The reflectors are usually suitable for a type of lamp and can not be replaced after the final assembly of the lamp or only with considerable effort. Furthermore, the prefabricated reflectors have the disadvantage that they require a lot of space due to their three-dimensional shape during storage and transport.
Aufgabe der vorliegenden Erfindung ist es, eine Leuchte der eingangs genannten Art zur Verfügung zu stellen, welche einen zur Montage und Demontage leichter zu handhabenden Reflektor aufweisen.Object of the present invention is to provide a luminaire of the type mentioned above, which have an easier to handle assembly and disassembly reflector.
Die Aufgabe wird gelöst durch eine Leuchte, insbesondere Leuchte für Beleuchtungszwcke, Innenraumleuchte oder Außenleuchte, z.B. Deckeneinbau- oder -anbauleuchte, Pendelleuchte, Steh- oder Wandleuchte, mit einem Gehäuse, das wenigstens zwei gegenüberliegende Wände aufweist, wenigstens einem Leuchtmittel und einem Reflektor, der von einer Lichtaustrittsseite der Leuchte betracht hinter dem Leuchtmittel angeordnet ist, wobei der Reflektor aus einem flexiblen Reflektorflachmaterial gebildet ist, welches im spannungsfreien Zustand eben ist, und zwischen den beiden Wänden eingespannt ist, so dass durch eine Eigenspannung des Reflektorflachmaterials sich eine Krümmung des Reflektors in einem Querschnitt senkrecht zu den Seitenwänden ausbildet, um einen Teil des vom Leuchtmittel abgegebenen Lichts umzulenken.The object is achieved by a lamp, in particular light for lighting toe, interior light or outdoor light, e.g. Ceiling recessed or surface-mounted luminaire, pendant luminaire, floor or wall luminaire, with a housing having at least two opposite walls, at least one light source and a reflector, which is arranged behind the illuminant from a light exit side of the lamp, wherein the reflector of a flexible Reflector flat material is formed, which is flat in the tension-free state, and is clamped between the two walls, so that a curvature of the reflector in a cross section perpendicular to the side walls is formed by an internal stress of the reflector sheet to deflect a portion of the light emitted from the light source.
Die Verwendung von flexiblem Reflektorflachmaterial ermöglicht den Reflektor einfach zu montieren und zu demontieren. Erfindungsgemäß wurde erkannt, dass die für Lichtlenkung benötigte Form des Reflektors alleine durch ein Einspannen des Reflektorflachmaterial zwischen zwei Wände des Gehäuses erzielt werden kann, weil sich das Reflektormaterial durch seine Eigenspannung von selbst krümmt. Wie der Fachmann erkennt, kann durch die Wahl der Abstände der gegenüberliegenden Wände sowie ggf. weiterer Anlagepunkte des Reflektors innerhalb des Gehäuses die Krümmung der Reflektoroberfläche definiert werden. Diese Art der Leuchte eignet sich insbesondere für flache Leuchtendesigns, z.B. Deckeneinbau- oder -anbauleuchten, die in Bezug auf die Lichtaustrittsfläche einen verhältnismäßig großen Reflektor mit vergleichsweise geringer Krümmung aufweisen.The use of flexible reflector sheet material makes the reflector easy to assemble and disassemble. According to the invention, it has been recognized that the shape of the reflector required for light guidance can be achieved solely by clamping the reflector flat material between two walls of the housing can be achieved because the reflector material curves by its own stress of its own accord. As the person skilled in the art realizes, the curvature of the reflector surface can be defined by the choice of the distances between the opposite walls and optionally further contact points of the reflector within the housing. This type of luminaire is particularly suitable for flat luminaire designs, eg recessed ceiling or surface mounted luminaires, which have a relatively large reflector with a comparatively small curvature with respect to the light exit surface.
Gemäß einer bevorzugten Ausführungsform weist das Reflektorflachmaterial an wenigstens einem Rand, der entlang einer der Wände verläuft, zwei oder mehr Laschen auf, die in zwei oder mehr Ausschnitte der betreffenden Wand eingesteckt sind. Die Lasche kann insbesondere eine Rechteck-, Dreieck-, Trapez- oder Halbkreisform aufweisen. Insbesondere ist wenigstens eine Seite mit einer Schräge zum leichten Einführen in den Ausschnitt vorgesehen. Die Ausschnitte in der betreffenden Wand weisen vorzugsweise eine Breite auf, welche der Breite der Lasche direkt am Rand des Reflektormaterials entspricht. Dadurch liegt die Lasche formschlüssig am Ausschnitt an. Gemäß bevorzugten Ausführungsformen sind mehr als zwei Laschen und Ausschnitte vorgesehen, um ein Durchbiegen des Reflektors in den Bereichen zwischen den Laschen entlang der Wand zu vermeiden.According to a preferred embodiment, the reflector sheet material has at least one edge extending along one of the walls, two or more tabs which are inserted in two or more sections of the wall in question. The tab may in particular have a rectangular, triangular, trapezoidal or semicircular shape. In particular, at least one side is provided with a slope for easy insertion into the cutout. The cutouts in the respective wall preferably have a width which corresponds to the width of the tab directly on the edge of the reflector material. As a result, the tab is positively on the neck. According to preferred embodiments, more than two tabs and cutouts are provided to prevent sagging of the reflector in the areas between the tabs along the wall.
Gemäß einer bevorzugten Ausführungsform weisen die Ausschnitte in der Wand eine Abmessung senkrecht zu dem anliegenden Rand des Reflektors auf, die ein Zurückschieben der Lasche entgegen der Eigenspannung des Reflektormaterials und ein Ausrücken der Lasche aus den Ausschnitten ermöglicht. Im montierten Zustand des Reflektors liegt die Lasche mit der dem Leuchtmittel zugewandten Oberfläche des Reflektorflachmaterials an einer Kante des Ausschnitts an. Durch Zurückschieben der Lasche entgegen der Eigenspannung kann die Lasche unter elastischer Verformung des Reflektors aus dem Ausschnitt gelöst werden. Vorzugsweise sind die Abmessungen der Ausschnitte senkrecht zu dem Rand größer als Fingerbreite, d.h. mehr als etwa 20 mm, um nach dem Zurückschieben der Lasche ein Durchgreifen des Ausschnitts zu ermöglichen, so dass die Lasche an ihrer Außenkante mit einem Finger durch den Ausschnitt ausgerückt werden kann. Dadurch lässt sich der Reflektor werkzeuglos aus dem Gehäuse demontieren. Im montierten Zustand des Reflektors ist der Ausschnitt jedoch nicht sichtbar, weil er von der Lichtaustrittsseite her gesehen hinter dem Reflektor liegt. Gemäß einer bevorzugten Ausführungsform liegt ein Abschnitt des Reflektors an einer Bodenwand des Gehäuses auf. Die Bodenwand kann die beiden Wände, zwischen denen der Reflektor eingespannt ist, verbinden. Durch die Auflage an einer Bodenwand, die vorzugsweise flächig ist, kann die Form des Reflektors im montierten Zustand weiter definiert werden. In den Bereichen des Reflektors, der an dem Gehäuse nicht anliegt, bildet sich eine kontinuierliche Krümmung aus. Die Krümmung wird bestimmt durch die Position der Reflektorränder, die an den Wänden anliegen, und der weiteren Auflage an dem Reflektorboden. Die Auflage an dem Reflektorboden ist vorzugsweise flächig, um dem anliegenden Bereich des Reflektors die gleiche Form wie dem Gehäuseboden zu geben. Beispielsweise kann der Boden eben sein. Dann ist im Bereich der Auflage der Reflektor ebenfalls eben. Es ist bevorzugt, dass das wenigstens eine Leuchtmittel in dem der Auflage des Reflektors gegenüberliegenden Raumbereich der Leuchte angeordnet ist. So wird eine definierte Lichtlenkung insbesondere durch den leuchnmittelnahen aufliegenden Reflektorabschnitt erzielt.According to a preferred embodiment, the cutouts in the wall have a dimension perpendicular to the adjacent edge of the reflector, which allows a pushing back of the tab against the residual stress of the reflector material and disengagement of the tab from the cutouts. In the assembled state of the reflector, the tab lies with the surface of the reflector flat material facing the luminous means at an edge of the cutout. By pushing back the tab against the residual stress, the tab can be solved under elastic deformation of the reflector from the neck. Preferably, the dimensions of the cutouts perpendicular to the edge are greater than finger widths, ie more than about 20 mm, to allow for the retraction of the tab to pass through the cutout, so that the tab can be disengaged at its outer edge with a finger through the cutout , As a result, the reflector can be removed from the housing without tools. In the assembled state of the reflector, however, the cutout is not visible, because it is behind the reflector as seen from the light exit side. According to a preferred embodiment, a portion of the reflector rests against a bottom wall of the housing. The bottom wall can connect the two walls, between which the reflector is clamped. Due to the support on a bottom wall, which is preferably flat, the shape of the reflector can be further defined in the mounted state. In the areas of the reflector, which does not rest against the housing, forms a continuous curvature. The curvature is determined by the position of the reflector edges, which bear against the walls, and the further support on the reflector base. The support on the reflector base is preferably flat in order to give the adjoining region of the reflector the same shape as the housing base. For example, the floor can be level. Then in the area of the support the reflector is also flat. It is preferred that the at least one luminous means is arranged in the area of the luminaire opposite the support of the reflector. Thus, a defined light control is achieved in particular by the luminaire-proximate resting reflector section.
Gemäß einer bevorzugten Ausführungsform können in Raumbereichen zwischen dem Gehäuse und dem Reflektor Betriebsmittel der Leuchte, z. B. Vorschaltgeräte, angeordnet sein.According to a preferred embodiment, in space regions between the housing and the reflector resources of the lamp, for. As ballasts, arranged.
Gemäß einer bevorzugten Ausführungsform weist die Leuchte Leuchtmittel in Form von einer oder mehreren, vorzugsweise parallel verlaufenden, röhrenförmigen Lampen, z.B. Leuchtstofflampen, auf. Die Lampen sind mit ihrer Längserstreckung vorzugsweise parallel zu den Wänden, zwischen denen der Reflektor eingespannt ist, angeordnet, weil entlang deiser Richtung der Reflektor gradlinig verläuft. Bevorzugte Lampen umfassen ferner auch LEDs oder OLEDs, z.B. am Boden des Gehäuses angeordnet. Der Reflektor kann neben den LEDs oder OLEDs enden und dort an einer Zwischenwand, z.B. einer Stufe, befestigt sein.According to a preferred embodiment, the lamp comprises lighting means in the form of one or more, preferably parallel, tubular lamps, e.g. Fluorescent lamps, on. The lamps are arranged with their longitudinal extent preferably parallel to the walls between which the reflector is clamped, because along this direction the reflector is rectilinear. Preferred lamps further include LEDs or OLEDs, e.g. arranged at the bottom of the housing. The reflector may end adjacent to the LEDs or OLEDs and there at an intermediate wall, e.g. a step, be attached.
Als Reflektorflachmaterial ist Kunststoff bevorzugt. Insbesondere kann ein aufgeschäumtes PET-Material (micro cell polyethylen terephthalat) als Reflektormaterial angewandt werden. Diese Materialien weisen eine Elastizität auf, die eine gleichmäßige Krümmung im eingespannten Zustand des Reflektors ermöglichen.As the reflector sheet plastic is preferred. In particular, a foamed PET material (micro cell polyethylene terephthalate) can be used as a reflector material. These materials have an elasticity that allows a uniform curvature in the clamped state of the reflector.
Die Stärke des Reflektormaterials beträgt vorzugsweise zwischen 0,5 mm und 1,5 mm.The thickness of the reflector material is preferably between 0.5 mm and 1.5 mm.
Gemäß bevorzugten Ausführungsformen weist die erfindungsgemäße Leuchte ein flaches Gehäuse auf. Es sind Verhältnisse von der Höhe zu der Breite der Leuchte im Querschnitt senkrecht zu den Wänden, zwischen denen der Reflektor eingespannt ist, von 7:20 bis 7:60 bevorzugt. Diese Leuchten eignen sich insbesondere als Deckenleuchten zur Montage an oder in der Decke.According to preferred embodiments, the luminaire according to the invention has a flat housing. There are ratios of the height to the width of the lamp in cross section perpendicular to the walls, between which the reflector is clamped, preferably from 7:20 to 7:60. These lights are particularly suitable as ceiling lights for mounting on or in the ceiling.
