Description

Die Erfindung betrifft ein Leuchtsystem zur vorzugsweise indirekten Raumbeleuchtung mit einer Profilschiene und einem längs der Profilschiene verlaufenden LED-Leuchtband.The invention relates to a lighting system for preferably indirect room lighting with a profile rail and along the profile rail extending LED light strip.

Aus der DE 10 2008 056 958 A1 ist ein Leuchtsystem insbesondere zum Einbau in Wand- oder Bodenbeläge oder Treppen bekannt, bei dem ein halboffener Leuchtkanal in einer Profilschiene durch eine lichtdurchlässige Abdeckleiste überdeckt wird. Dadurch ergibt sich eine einheitliche Oberfläche, wobei jedoch die einzelnen LEDs unter der Abdeckleiste erkennbar sind.From the DE 10 2008 056 958 A1 a luminous system is known in particular for installation in wall or floor coverings or stairs, in which a semi-open light channel is covered in a rail by a translucent cover strip. This results in a uniform surface, but the individual LEDs are visible under the cover strip.

Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, die im Stand der Technik bekannten Systeme weiter zu entwickeln und eine möglichst einfache Montage und Integration einer insbesondere indirekten Raumbeleuchtung in einen Gebäuderaum zu ermöglichen.Proceeding from this, the present invention seeks to further develop the systems known in the art and to allow the simplest possible installation and integration of a particular indirect room lighting in a building room.

Zur Lösung dieser Aufgabe wird die im Patentanspruch 1 bzw. 15 angegebene Merkmalskombination vorgeschlagen. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.To solve this problem, the combination of features specified in claim 1 and 15 is proposed. Advantageous embodiments and modifications of the invention will become apparent from the dependent claims.

Die Erfindung geht von dem Gedanken aus, eine lineare Leuchte in Form einer einfach zusammensteckbaren Profilanordnung zu schaffen. Demzufolge wird erfindungsgemäß vorgeschlagen, dass ein Steckprofilteil in eine Aufnahme der Profilschiene unter Bildung einer Profilnut eingesteckt bzw. eingeklemmt ist, wobei das LED-Leuchtband in der Profilnut gehalten ist und Licht über die Öffnung der Profilnut abstrahlen kann. Das LED-Leuchtband besteht allgemein aus einem Trägerstreifen bzw. Trägerband und darauf reihenförmig angeordneten Leuchtdioden (LEDs). Die Profilschiene, das Steckprofilteil und die durch Einstecken des Steckprofilteils gebildete Profilnut besitzen in Längsrichtung gesehen ein jeweils durchgehendes Profil bzw. einen einheitlichen Querschnitt. Damit lässt sich eine auch für Montage- und Reparaturzwecke leicht zugängliche geschützte Halterung eines Leuchtbandes in einem Profilsystem realisieren, wobei die Leuchtdioden als eigentliche Lichterzeuger in der Profilnut verborgen sind und das Licht blendfrei abgestrahlt werden kann.The invention is based on the idea to create a linear lamp in the form of a simple mating profile arrangement. Accordingly, the invention proposes that a male profile part is inserted or clamped in a recording of the rail to form a profile groove, wherein the LED light strip is held in the profile and can radiate light through the opening of the profile. The LED strip generally consists of a carrier strip or carrier tape and in rows arranged light-emitting diodes (LEDs). The profile rail, the male profile part and the profile groove formed by insertion of the male profile part have seen in the longitudinal direction a respective continuous profile or a uniform cross-section. This allows a readily accessible for mounting and repair purposes protected holder of a light strip in a profile system realize, the light-emitting diodes are hidden as the actual light generator in the profile and the light can be emitted glare-free.

Vorteilhafterweise besitzt die Profilschiene eine konkav gewölbte, die Öffnung der Profilnut im Abstand übergreifende übergreifende Reflektorfläche, so dass eine indirekte, gleichmäßige Lichtabstrahlung möglich ist.Advantageously, the profile rail has a concavely curved, the opening of the profile groove at a distance across cross-reflector surface, so that an indirect, uniform light emission is possible.

Zur weiteren Erhöhung der Montagefreundlichkeit ist es von Vorteil, wenn das Steckprofilteil von der Profilschiene abnehmbar, insbesondere werkzeuglos lösbar ist, so dass das LED-Leuchtband seitlich zugänglich ist. Eine weitere Verbesserung in dieser Hinsicht ergibt sich dadurch, dass die Profilnut jeweils eine durch die Profilschiene und das Steckprofilteil gebildete Nutflanke aufweist.To further increase the ease of installation, it is advantageous if the male profile part of the rail is removable, in particular without tools, so that the LED strip light is accessible from the side. A further improvement in this respect results from the fact that the profile groove in each case has a groove flank formed by the profile rail and the plug profile part.

Um eine zuverlässige Halterung zu ermöglichen, ist es günstig, wenn die Öffnung der Profilnut durch gegeneinander weisende Profilrippen der Profilschiene und des Steckprofilteils mit einer Hinterschneidung begrenzt ist.In order to enable a reliable mounting, it is advantageous if the opening of the profile groove is limited by mutually facing profile ribs of the rail and the male profile part with an undercut.

Eine werkzeuglos herstell- und lösbare Verbindung lässt sich dadurch verwirklichen, dass die Profilschiene zwei parallel zueinander verlaufende Profilstege als Aufnahme zur Klemmverbindung eines steckbaren Profilschenkels des Steckprofilteils aufweist.A tool-less producible and detachable connection can be realized in that the profile rail has two mutually parallel profile webs as a receptacle for clamping connection of a plug-in profile leg of the male profile part.

Zur weiteren Verbesserung der Einbaumöglichkeiten ist es von Vorteil, wenn die Profilschiene einen als Profilelement längsseitig abstehenden vorzugsweise gelochten Steg zum Anbringen von Fliesen aufweist.To further improve the installation options, it is advantageous if the profile rail has a profiled element protruding longitudinally preferably perforated web for attaching tiles.

Um die elektrische Schaltungsanordnung zu schützen, ist es vorteilhaft, wenn das LED-Leuchtband einen transparenten Trägerschlauch und einen darin eingeschlossenen, reihenförmig mit LEDs bestückten Trägerstreifen (LED-Strip) aufweist.In order to protect the electrical circuit arrangement, it is advantageous if the LED strip light has a transparent carrier tube and a carrier strip (LED strip) enclosed therein in rows and equipped with LEDs.

Zum Anfügen an eine Deckenkante einer Raumwand ist es vorteilhaft, wenn die Profilschiene ein geeignet geformtes, vorzugsweise rechtwinkliges Winkelstück als Profilelement aufweist.For attachment to a ceiling edge of a room wall, it is advantageous if the profile rail has a suitably shaped, preferably right-angled angle piece as profile element.

Für die Montage als Sockelleiste ist es von Vorteil, wenn die Profilschiene einen Stützfuß zur Abstützung an einer Bodenkante aufweist.For mounting as skirting it is advantageous if the rail has a support leg for support on a bottom edge.

Die harmonische Eingliederung lässt sich dadurch weiter verbessern, dass das Steckprofilteil eine an einer Sichtseite konvex gewölbte Blende aufweist.The harmonic integration can be further improved in that the male profile part has a convexly curved on a visible side panel.

Um entsprechend den baulichen Gegebenheiten vor Ort gegebenenfalls auch winklige zusammengesetzte Konfigurationen zu ermöglichen, ist es günstig, wenn die Profilschiene einen stirnseitig offenen Profilkanal für einen Steckverbinder zur Verbindung mehrerer Schienenabschnitte aufweist.In order to allow according to the structural conditions on site, if necessary, also angular composite configurations, it is advantageous if the rail has a frontally open profile channel for a connector for connecting a plurality of rail sections.

Auch herstellungstechnisch ist es von besonderem Vorteil, wenn die Profilschiene und das Steckprofilteil aus einem Strangpressprofil insbesondere aus Aluminium bestehen.Also manufacturing technology, it is particularly advantageous if the rail and the male profile part of an extruded profile in particular made of aluminum.

Auch aus gestalterischen Gründen ist es vorteilhaft, wenn die Profilschiene an mindestens einem Ende durch einen eingesetzten Deckel stirnseitig abgedeckt ist.Also, for design reasons, it is advantageous if the rail is covered at least at one end by a lid inserted end face.

Eine besondere Variante der Erfindung besteht in einem Leuchtsystem zur indirekten Raumbeleuchtung mit einer Profilschiene und einem längs der Profilschiene verlaufenden, reihenförmig mit Leuchtdioden bestückten LED-Leuchtband, wobei das LED-Leuchtband in einer Profilnut der Profilschiene gehalten ist und Licht über die Öffnung der Profilnut abstrahlen kann, und wobei die Profilschiene eine im Querschnitt konkav gewölbte, die Öffnung der Profilnut übergreifende Reflektorfläche zur Lichtumlenkung aufweist. Dadurch lässt sich ebenfalls eine indirekte Beleuchtung mit verdecktem Leuchtband erreichen, wobei das LED-Band dann über die Nutöffnung oder über die offene Stirnseite der Profilschiene eingesetzt werden kann und in dieser Konfiguration ebenfalls die vorstehend genannten Ausgestaltungen und Weiterbildungen sowie deren vorteilhafte Wirkungen mit Ausnahme der Teilbarkeit der Profilnut erreichbar sind.A particular variant of the invention consists in a lighting system for indirect room lighting with a profile rail and a longitudinally extending rail, row-like equipped with LEDs LED strip light, wherein the LED strip light is held in a profile of the profile rail and can radiate light through the opening of the profile groove, and wherein the profile rail has a concave in cross section, the opening of the profile groove cross reflector surface for light deflection. As a result, indirect illumination with concealed luminous band can also be achieved, the LED band then being able to be inserted via the slot opening or via the open front side of the profile rail and, in this configuration, likewise the abovementioned refinements and developments and their advantageous effects with the exception of divisibility the profile groove can be reached.

Im Folgenden wird die Erfindung der in der Zeichnung in schematischer Weise dargestellten Ausführungsbeispiele näher erläutert. Es zeigen:

In the following the invention of the embodiments schematically illustrated in the drawing will be explained in more detail. Show it:
Fig. 1
a lighting system as a ceiling strip for combination with a tile covering in a sectional perspective view;
Fig. 2
a further embodiment of a lighting system as skirting in a sectional perspective view.

Das erfindungsgemäße Leuchtsystem 10 lässt sich längs einer Decken- oder Bodenkante für eine indirekte Raumbeleuchtung installieren. Es umfasst zu diesem Zweck eine Profilschiene 12 mit einer konkav gewölbten Reflektorfläche 14 und ein in Schienenlängsrichtung verlaufendes LED-Leuchtband 16, das durch ein Steckprofilteil 18 in einer Profilnut 20 gehalten ist und Licht über die Öffnung 22 der Profilnut auf die Reflektorfläche 14 abstrahlen kann.The lighting system 10 according to the invention can be installed along a ceiling or floor edge for indirect room lighting. It comprises for this purpose a profile rail 12 with a concave reflector surface 14 and extending in the rail longitudinal LED light strip 16, which is held by a male profile part 18 in a profile groove 20 and can radiate light through the opening 22 of the profile on the reflector surface 14.

Bei dem in Fig. 1 gezeigten Ausführungsbeispiel besitzt die als Strangpressprofilabschnitt ausgebildete Profilschiene 12 einen nach unten abstehenden Flanschsteg 24 zur hintergreifenden Aufnahme von nicht gezeigten Fliesen. Hierfür weist der Flanschsteg 24 eine Lochstruktur 26 zur besseren Klebeverbindung auf. Im Verbindungszustand schließen die Fliesen flächenbündig an den Außenschenkel 28 des Steckprofilteils 18 an. An ihrem oberen Abschnitt weist die Profilschiene 12 ein Winkelstück 30 zum Anfügen an eine Deckenkante einer Raumwand auf. Auf diese Weise kann ein gefliester Wandbelag beispielsweise in einem Badezimmer durch eine lineare Leuchtanordnung nach oben abgeschlossen werden, wobei das Licht über den konkav gewölbten Reflektor 14 indirekt an die Decke bzw. in den Raum abgestrahlt wird.At the in Fig. 1 the embodiment shown as extruded profile section 12 has a downwardly projecting flange web 24 for engaging behind recording of tiles, not shown. For this purpose, the flange web 24 has a hole structure 26 for a better adhesive connection. When connected, the tiles close flush on the outer leg 28 of the male profile part 18. At its upper portion, the rail 12 has an elbow 30 for attachment to a ceiling edge of a room wall. In this way, a tiled wall covering can be completed, for example, in a bathroom by a linear lighting arrangement upwards, the light is emitted via the concave reflector 14 indirectly to the ceiling or in the room.

Das LED-Leuchtband 16 ist in der Profilnut 20 formschlüssig und/oder stoffschlüssig fixiert. Zur Herstellung einer Formschlussverbindung ist die Öffnung 22 der Profilnut 20 durch gegeneinander weisende Profilrippen 32, 34 der Profilschiene und des Steckprofilteils hinterschnitten begrenzt. Dabei weist die Profilnut 20 jeweils eine durch die Profilschiene und das Steckprofilteil gebildete Nutflanke 36, 38 auf.The LED light strip 16 is fixed in the profile groove 20 positively and / or cohesively. To produce a positive connection, the opening 22 of the profile groove 20 is limited by mutually facing profile ribs 32, 34 of the rail and the male profile part undercut. In this case, the profile groove 20 each have a groove formed by the rail and the male profile part groove flank 36, 38.

Für Montage- und Reparaturzwecke ist das Steckprofilteil 18 von der Profilschiene 12 lösbar, so dass das LED-Leuchtband 16 seitlich einführbar bzw. zugänglich ist. Um dies werkzeuglos zu ermöglichen, sind an der Profilschiene 12 zwei parallel zueinander verlaufende Profilstege 40 angeformt, die eine Aufnahme 42 zur lösbaren Klemmverbindung eines Steckschenkels 44 des Steckprofilteils 18 bilden.For assembly and repair purposes, the male profile part 18 of the rail 12 is detachable, so that the LED light strip 16 is laterally inserted or accessible. To make this possible without tools, two mutually parallel profile webs 40 are integrally formed on the rail 12, which form a receptacle 42 for releasable clamping connection of a plug leg 44 of the male profile part 18.

Zur reihenförmigen Verbindung mehrerer auf eine gewünschte Länge abgelängter Profilschienen 12 ist zwischen dem Reflektor 14 und dem Winkelstück 30 ein Profilkanal 46 freigehalten, der an seiner offenen Stirnseite das Einführen von geeigneten Steckverbindern erlaubt.For row-like connection of a plurality of cut to a desired length of profile rails 12, a profile channel 46 is kept free between the reflector 14 and the elbow 30, which allows the insertion of suitable connectors on its open end.

Weiterhin ist es auch möglich, Profilschienenabschnitte ohne Flansch- bzw. Fliesensteg 24 als sogenannte Wohnraumprofile einzusetzen, um nicht geflieste Wandbereiche zu übergreifen. Beispielsweise sind bei modernen Bauten die Bad- und Wohnräume oft eng miteinander verbunden, so dass auch hier geflieste und nicht geflieste Wandbereiche übergangslos einbezogen werden können. Dies gilt auch, wenn ein Bad nicht durchgehend gefliest wird, wobei die verputzen Wandbereiche mit Wohnraumprofilen bestückt werden, die dann entweder an die Wand geklebt oder geschraubt werden können.Furthermore, it is also possible to use profile rail sections without flange or tile web 24 as so-called living space profiles in order to not overlap tiled wall areas. For example, in modern buildings, the bathrooms and living rooms are often closely connected, so that even here tiled and non-tiled wall areas seamlessly included can be. This is also true if a bathroom is not tiled throughout, with the plastered wall areas are populated with housing profiles, which can then either be glued to the wall or screwed.

Für den Einsatz in feuchter Umgebung kann das LED-Leuchtband 16 einen transparenten Trägerschlauch 46 besitzen, der einen LED-Strip 48 hermetisch einschließt. Dieser ist mit Leiterbahnen und LED-Bausteinen 50 sowie ggf. weiteren Elektronik-Bauelementen bestückt. Die LED-Bausteine 50 sind bevorzugt in SMD-Technik ausgeführt (Surface Mounted Devices = oberflächenmontierte Bauteile). Hierbei können einfarbige oder wahlweise ansteuerbare mehrfarbige LEDs zum Einsatz kommen.For use in humid environments, the LED light strip 16 may have a transparent carrier tube 46 hermetically enclosing an LED strip 48. This is equipped with interconnects and LED modules 50 and possibly other electronic components. The LED modules 50 are preferably implemented using SMD technology (Surface Mounted Devices). In this case, single-color or optionally controllable multicolor LEDs can be used.

Bei dem in Fig. 2 dargestellten Ausführungsbeispiel, das ein Leuchtsystem 10 als Sockelprofil zur bodenseitigen indirekten Wohnraumbeleuchtung zeigt, sind gleiche oder ähnliche Teile mit gleichen Bezugszeichen wie vorstehend erläutert gezeigt. Die Profilschiene 12 weist hier anstelle des Winkelstücks 30 einen abgewinkelten Stützfuß 52 zur Abstützung an einer Bodenfläche auf. Der Stützfuß 52 steht hinter der Vorderkante des Reflektors 14 nach unten ab und erlaubt somit das Anbringen einer Silikonfuge in dem Spalt 54. Zugleich begrenzt der nach hinten abgewinkelte Bereich einen verdeckten Kabelkanal 56. Das LED-Leuchtband 16 kann im Wohnraumbereich ohne Trägerschlauch am Grund der Profilnut 20 eingeklebt werden. Zweckmäßig ist an der Innenseite der Nutflanke 36 eine Profilrille 60 eingeformt, die ein lagerichtiges Einbringen von Bohrungen für Befestigungsschrauben erleichtert. Das erzeugte Licht wird wiederum über die Öffnung 32 der Profilnut 20 auf den konkaven Reflektor 14 abgestrahlt und von dort in den Bodenbereich des Wohnraums umgelenkt. Für eine harmonische Gestaltung kann an einem sichtseitigen oberen Abschnitt des Steckprofils 18 eine konvex gewölbte Profilblende 58 angeformt sein.At the in Fig. 2 illustrated embodiment, which shows a lighting system 10 as a base profile for the bottom-side indirect living room lighting, the same or similar parts are shown with the same reference numerals as explained above. The rail 12 has here instead of the elbow 30 an angled support leg 52 for support on a bottom surface. The support leg 52 is behind the front edge of the reflector 14 downwards and thus allows the attachment of a silicone joint in the gap 54. At the same time limits the back angled area a hidden cable channel 56. The LED light strip 16 can in the living area without a carrier hose at the bottom of Profile groove 20 are glued. Appropriately, a profile groove 60 is formed on the inside of the groove side 36, which facilitates a correct position introduction of holes for fastening screws. The generated light is in turn emitted via the opening 32 of the profile groove 20 onto the concave reflector 14 and deflected from there into the floor area of the living space. For a harmonious design, a convex curved profile panel 58 may be integrally formed on a visible upper section of the plug-in profile 18.
