Description

Die Erfindung betrifft einen Schallabsorber mit einem in einem Rahmenteil aufgenommenen, eine Außenfläche aufweisenden Absorberteil, wobei das Absorberteil außenseitig zumindest teilweise lichtreflektierend ausgebildet ist, beispielsweise lichtreflektierende Elemente, etwa gebildet durch ein Glasfaservlies, aufweist.The invention relates to a sound absorber with a received in a frame part, an outer surface having absorber part, wherein the absorber part is externally formed at least partially light-reflecting, for example, light-reflecting elements, such as formed by a glass fiber fleece having.

Derartige Schallabsorber sind bereits in vielfältiger Ausgestaltung bekannt geworden. Es wird beispielsweise auf die DE 10 2006 051 567 A1 verwiesen.Such sound absorbers have already become known in a variety of configurations. It is for example on the DE 10 2006 051 567 A1 directed.

Mit einem derartigen Schallabsorber ausgestattete Räume bedürfen oftmals auch einer Ausleuchtung. Die Erfindung beschäftigt sich mit der Aufgabe, eine günstige Ausleuchtung eines mit einem Schallabsorber versehenen Raumes anzugeben.Rooms equipped with such a sound absorber often also require illumination. The invention is concerned with the task of providing a favorable illumination of a space provided with a sound absorber.

Eine mögliche Lösung der Aufgabe ist nach einem ersten Erfindungsgedanken durch den Gegenstand des Anspruches 1 gegeben, wobei darauf abgestellt ist, dass in dem Rahmenteil quer zu der Außenfläche abstrahlende Leuchtelemente angeordnet sind. Die Leuchtelemente sind kombiniert oder unmittelbar verbunden mit dem Schallabsorber ausgebildet. Der Schallabsorber wirkt sowohl in akustischer Hinsicht wie auch in lichttechnischer Hinsicht. Durch die kombinierte Ausbildung von Schallabsorber und Leuchtelementen ist eine bereits herstellerseitig optimale Anpassung des Absorbers und der Leuchtelemente in lichttechnischer Hinsicht möglich. Im Einzelnen kann die Ausgestaltung so vorgesehen sein, dass in üblicher Weise ein An- und Ausschalten der Leuchtelemente, ggf. auch nur teilweise, ermöglicht ist. Der Schallabsorber kann hierbei unmittelbar an der Decke eines Raumes oder abgehängt von der Decke des Raumes angebracht sein. Er kann auch an einer senkrechten Wand angebracht sein. Die Leuchtelemente sind gleichsam umlaufend zu dem Absorberteil angeordnet. Insbesondere bei einem an einer Raumdecke angebrachten Schallabsorber ergibt sich im Wechsel mit einem etwa darunter befindlichen Tisch eine Reflektion des Lichtes zum Inneren des durch die Leuchtelemente gebildeten umlaufenden Kranzes, wodurch das Licht auf die lichtreflektierenden Elemente oder Bereiche des Schallabsorbers trifft, so dass sich eine flächenmäßig gleichförmige strahlende bzw. lichtreflektierende Fläche ergibt. Dadurch, dass die lichtreflektierenden Elemente, wie etwa gebildet durch ein Glasfaservlies, das Licht diffus reflektieren, ergeben sich angenehme Lichtverhältnisse über einem beispielsweise Tisch.A possible solution of the problem is given by a first inventive thought by the subject of claim 1, wherein it is aimed that are arranged in the frame part transversely to the outer surface radiating light elements. The lighting elements are combined or formed directly connected to the sound absorber. The sound absorber works both acoustically and in terms of lighting technology. Due to the combined formation of sound absorber and lighting elements, an already optimal adjustment of the absorber and the lighting elements in terms of lighting technology is possible. In detail, the embodiment can be provided so that in the usual way a switching on and off of the lighting elements, possibly even only partially, is possible. The sound absorber can be attached directly to the ceiling of a room or suspended from the ceiling of the room. It can also be attached to a vertical wall. The lighting elements are arranged as it were circumferentially to the absorber part. Especially with a sound absorber attached to a room ceiling results in alternation with an approximately underlying table, a reflection of the light to the interior of the circumferential ring formed by the light elements, whereby the light strikes the light-reflecting elements or areas of the sound absorber, so that there is a radiant uniformly radiant or light-reflecting surface. The fact that the light-reflecting elements, such as formed by a glass fiber fleece, reflect the light diffusely, resulting in pleasant lighting conditions on a table, for example.

Ein weiterer Aufgabenteil, aber auch eine unabhängige eigenständige Aufgabe ist darin zu sehen, bestehende Schallabsorber lichttechnisch günstig weiterzuentwickeln.Another task, but also an independent independent task is to see existing existing sound absorbers photometrically favorable development.

Eine mögliche Lösung dieses weiteren Aspektes ist durch ein Zusatz-Rahmenteil gegeben mit einem darin aufgenommenen Leuchtelement, wobei das Zusatz-Rahmenteil einen Verbindungsabschnitt aufweist zum Verbinden mit einem Haupt-Rahmenteil eines Schallabsorbers. Bestehende Schallabsorber können so nachgerüstet werden bzw. herstellungstechnisch können Schallabsorber teilweise oder vollumfänglich an ihrem Rahmen mit dem Leuchtmittel-Rahmen ausgerüstet werden.A possible solution to this further aspect is given by an additional frame part with a light element received therein, wherein the additional frame part has a connecting portion for connection to a main frame part of a sound absorber. Existing sound absorbers can be retrofitted or manufacturing technology sound absorbers can be partially or fully equipped on their frame with the bulb frame.

Weitere Merkmale der Erfindung sind nachstehend, auch in der Figurenbeschreibung, oftmals in ihrer bevorzugten Zuordnung zu den bereits vorstehend behandelten Anspruchskonzepten erläutert, sie können aber auch in einer Zuordnung zu nur einem oder mehreren einzelnen Merkmalen dieser Ansprüche oder unabhängig oder in einem anderen Gesamtkonzept von Bedeutung sein.Further features of the invention are explained below, also in the description of the figures, often in their preferred assignment to the already discussed claim concepts, but they can also be assigned to only one or more individual features of these claims or independently or in another overall concept of meaning be.

So ist es zunächst bevorzugt, dass auch weiteren Leuchtelementen, abgehängt von dem Absorber, also in einer Überdeckung zu einer Projektion der Absorberfläche nach unten, angeordnet sind. Sie können etwa unterseitig mit einer Lichtabdeckung oder nur teilweise lichtdurchlässigen Abdeckung versehen sein, so dass eine Anstrahlung nach oben, gegen die Absorberfläche (zunächst) erfolgt und von da aus das Licht wieder reflektiert wird.Thus, it is firstly preferred that further luminous elements, suspended from the absorber, that is, in an overlap to a projection of the absorber surface down, are arranged. They can be provided on the underside with a light cover or only partially translucent cover be, so that a radiation upward, against the absorber surface (initially) takes place and from there the light is reflected again.

Bevorzugt ist auch, dass das Licht dimmbar ist bzw. soweit LED-Leuchten vorgesehen sind, dass die Lichtfarbe veränderbar ist.It is also preferred that the light is dimmable or as far as LED lights are provided that the light color is changeable.

Weiter ist bevorzugt, dass die Leuchtelemente als LEDs, also Leuchtdioden, ausgebildet sind. Das Licht der Leuchtdioden harmoniert günstig mit den beispielsweise durch ein Glasfaservlies gebildeten reflektierenden Elementen an dem Absorberteil.It is further preferred that the light-emitting elements are designed as LEDs, that is to say light-emitting diodes. The light of the light-emitting diodes harmonizes favorably with the reflective elements formed, for example, by a glass fiber fleece on the absorber part.

Im Hinblick auch auf den bereits angesprochenen weiteren Aufgabenaspekt kann das Rahmenteil zweigeteilt ausgebildet sein, wobei ein Zusatz-Rahmenteil, das abnehmbar an dem Haupt-Rahmenteil befestigt ist, die Leuchtelemente enthält. Die Zweiteilung ist hierbei in Längsrichtung des Rahmenteils vorgesehen, also in Umlaufrichtung bezüglich eines beispielsweise einen rechteckigen Grundriss aufweisenden Absorberteils. Bevorzugt umgeben die Leuchtelemente, bei gewisser Beabstandung untereinander in Umfangsrichtung, das Absorberteil auch auf dessen gesamtem Umfang. Hierbei können einzelne Leuchtdioden im Hinblick auf den Abstand untereinander in Umfangsrichtung, oder sonstige Leuchtelemente, etwa mit einem Abstand von 1 cm bis 10 cm zueinander, wobei auch alle Zwischenwerte, insbesondere in 1-mm-Schritten, in die Offenbarung einbezogen sind, angeordnet sein.With regard to the already mentioned further task aspect, the frame part may be formed in two parts, wherein an additional frame part which is detachably attached to the main frame part, containing the lighting elements. The division into two is hereby provided in the longitudinal direction of the frame part, that is to say in the direction of rotation with respect to an absorber part having, for example, a rectangular outline. Preferably, the luminous elements, with a certain spacing between them in the circumferential direction, surround the absorber part also on its entire circumference. In this case, individual light-emitting diodes with respect to the distance from each other in the circumferential direction, or other lighting elements, for example, with a distance of 1 cm to 10 cm to each other, whereby all intermediate values, in particular in 1-mm increments, are included in the disclosure, be arranged ,

Die Leuchtelemente sind weiter bevorzugt nach unten durch eine Scheibe, insbesondere eine als Streulichtscheibe wirkende lichtdurchlässige Scheibe abgedeckt. Hierbei ist auch bevorzugt, dass die Scheibe bzw. Streulichtscheibe oder eine Strahlfläche bzw. ein unterer Bereich der Leuchtelemente selbst etwa ebenengleich mit der im Montagezustand dem Raum zugewandten Außenfläche des Absorberteils angeordnet sind. Es kann auch ein gewisser vertikaler Abstand, beispielsweise im Bereich von 1 cm bis 2 cm, vorgesehen sein. Hinsichtlich des Zusatz-Rahmenteils ist insbesondere weiter bevorzugt, dass der Verbindungsabschnitt als Übergriff-Verbindungsabschnitt ausgebildet ist. In einem Querschnitt ergibt sich also ein Übergreifbereich über das Haupt-Rahmenteil. Das Zusatz-Rahmenteil ist entsprechend außenseitig, im Montagezustand dann den Außenrand des Schallabsorbers bildend, angeordnet.The light-emitting elements are further preferably covered downwards by a pane, in particular a light-permeable pane acting as a scattered light pane. In this case, it is also preferred that the pane or scattered-light pane or a jet area or a lower area of the lighting elements themselves be arranged approximately level with the outer area of the absorber part facing the space in the assembled state. It may also be a certain vertical distance, for example in the range of 1 cm to 2 cm, be provided. With regard to the additional frame part, it is particularly preferred in particular for the connecting section to be designed as an overlapping connecting section. In a cross-section, therefore, an overlap region results over the main frame part. The additional frame part is according to the outside, then forming the outer edge of the sound absorber in the assembled state arranged.

Auch ist bevorzugt, dass das Zusatz-Rahmenteil alternativ oder ergänzend zu dem übergreifend zur Einhäng-Befestigung an dem Haupt-Rahmenteil ausgebildet ist.It is also preferred that the additional frame part is designed as an alternative or in addition to the overarching to the hooking attachment to the main frame part.
