Abstract
Description
Die Erfindung betrifft eine Leuchte zum großflächigen Beleuchten von Wänden oder Decken in Räumen sowie von Außenfassaden bei Gebäuden nach dem Oberbegriff des Anspruchs 1.The invention relates to a luminaire for large-area lighting of walls or ceilings in rooms and of external facades in buildings according to the preamble of
Das Beleuchtungsprinzip der sogenannten Wallwasher wird für die Beleuchtung von Räumen bislang selten eingesetzt, eigentlich immer nur dann, wenn Kunst beleuchtet werden soll. Das Prinzip des Wallwashers besteht darin, daß die Wand (oder die Decke) in Räumen großflächig angestrahlt wird.The lighting principle of the so-called wallwasher is rarely used for the illumination of rooms, actually only when art is to be illuminated. The principle of the Wallwashers is that the wall (or the ceiling) is irradiated in large areas over a large area.
Derartige Leuchten weisen grundsätzlich ein Gehäuse auf, in welchem wenigstens eine Lampe angeordnet ist. Der Nachteil bei diesen Leuchten besteht darin, daß eine großflächige Beleuchtung von Wänden oder Decken in Räumen sowie von Außenfassaden bei Gebäuden mit großer Variabilität bislang nicht möglich ist.Such lights basically have a housing in which at least one lamp is arranged. The disadvantage of these lights is that a large-scale lighting of walls or ceilings in rooms and outdoor facades in buildings with great variability is not possible.

Der Erfindung liegt die Aufgabe zugrunde, eine Leuchte zum großflächigen, variablen Beleuchten von Wänden oder Decken in Räumen sowie von Außenfassaden bei Gebäuden zu schaffen.The invention has for its object to provide a lamp for large-scale, variable lighting of walls or ceilings in rooms and outdoor facades in buildings.
Die technische Lösung ist gekennzeichnet durch die Merkmale im Kennzeichen des Anspruchs 1.The technical solution is characterized by the features in the characterizing part of
Dadurch ist eine Leuchte geschaffen, mittels welcher mit einer großen Variabilität großflächige Beleuchtungen von Wänden oder Decken in Räumen sowie von Außenfassaden bei Gebäuden realisiert werden können. Das Grundprinzip der erfindungsgemäßen Leuchte besteht in einer Art Lichtstrich, d. h. einem Gehäuse in Form einer länglichen Leiste, welche nur wenige Zentimeter breit sowie hoch ist. Diese Leiste erstreckt sich über eine große Länge. Das Gehäuse kann an der Decke, als Deckenaufbau sowie als Deckeneinbauvariante montiert werden. Die Leuchte zeichnet sich aufgrund der Verwendung von LEDs durch eine hohe Effizienz bei geringem Energieeinsatz zur schneeweißen Aufhellung von Wänden und Decken aus, aber auch in allen anderen variablen Lichtfarben. Durch die Bestückung mit Multi-Chip-LEDs oder mit LEDs in den Grundfarben Rot, Gelb und Blau können die Wände in allen Farben des Regenbogens beleuchtet werden. Durch die Verwendung einer Linsenscheibe, welche das Gehäuse vorderseitig abschließt, ist eine gezielte Lichtabstrahlung der LEDs möglich. Konstruktiv ist die Platine im Bereich einer der beiden Innenlängskanten des Gehäuses angeordnet, so daß die LEDs innerhalb des Gehäuses schräg ausgerichtet sind und ihr Licht schräg aus dem Gehäuse abstrahlen. Mit der schrägen Anordnung der LEDs auf der einen Seite des Gehäuses und der speziellen Ausbildung der davor befindlichen Linsescheibe ist gewährleistet, daß die angestrahlte Wand oder Decke im Wesentlichen gleichmäßig über ihre gesamte Fläche beleuchtet wird. Je nach Ausbildung der Linse kann der Abstrahlwinkel der Leuchte variiert werden. Bei dieser Linse kann es sich um eine Art Quasi-Fresnellinse handeln. Die Linsenscheibe weist dabei über die Länge des Gehäuses gesehen immer die gleiche Querschnittsform auf. Somit schafft die erfindungsgemäße Leuchte mit ihren minimalen Abmessungen und geringem Energieeinsatz eine optimale, gleichmäßige Ausleuchtung der Wandfläche über die gesamte Höhe des Raumes in großer Variabilität. Durch den Einsatz der bereits erwähnten Mult-Chip-LEDs oder mit LEDs in den Grundfarben Rot, Gelb und Blau ist eine farbige Gestaltung der Wände von leichten Pastelltönen bis zu kräftigen Farben über das ganze Spektrum des Regenbogens möglich. Die erfindungsgemäße Leuchte ist aber auch für Nachtwirkung von Gebäuden mit wenig Energie und Licht einsetzbar.As a result, a lamp is created by means of which large-scale lighting of walls or ceilings in rooms and outdoor facades can be realized in buildings with a large variability. The basic principle of the luminaire according to the invention consists in a kind of light line, d. H. a housing in the form of an elongated strip, which is only a few inches wide and high. This bar extends over a great length. The housing can be mounted on the ceiling, as a ceiling structure or as a recessed ceiling version. Due to the use of LEDs, the luminaire stands out due to its high efficiency and low energy consumption for snow-white brightening of walls and ceilings, but also in all other variable light colors. By fitting multi-chip LEDs or LEDs in the primary colors red, yellow and blue, the walls can be illuminated in all the colors of the rainbow. Through the use of a lens disk, which closes the housing on the front side, a targeted light emission of the LEDs is possible. Structurally, the board is arranged in the region of one of the two inner longitudinal edges of the housing, so that the LEDs are aligned obliquely within the housing and radiate their light obliquely out of the housing. With the oblique arrangement of the LEDs on one side of the housing and the special design of the front lens disc ensures that the illuminated wall or ceiling is illuminated substantially uniformly over its entire surface. Depending on the design of the lens, the beam angle of the lamp can be varied. This lens may be a kind of quasi-Fresnel lens. The lens disk always has the same cross-sectional shape over the length of the housing. Thus, the luminaire according to the invention, with its minimal dimensions and low energy input, creates an optimal, uniform illumination of the wall surface over the entire height of the room in great variability. By using the aforementioned multichip LEDs or LEDs in the basic colors red, yellow and blue, a colorful design of the walls is possible, from light pastel shades to bold colors across the entire spectrum of the rainbow. The luminaire according to the invention, however, can also be used for the night effect of buildings with little energy and light.

Vorzugsweise sind gemäß der Weiterbildung in Anspruch 5 die LEDs auf einer gemeinsamen Platine in dem Gehäuse angeordnet.Preferably, according to the embodiment in
Eine bevorzugte Weiterbildung schlägt gemäß Anspruch 6 vor, daß vor jeder der LEDs eine sogenannte Primärlinse bzw. Primäroptik angeordnet ist, bei welcher es sich vorzugsweise um eine Sammellinse handelt. Diese Primärlinse ist rotationssymmetrisch ausgebildet und kann beispielsweise im wesentlichen als Kugelabschnitt, insbesondere im wesentlichen halbkugelförmig ausgebildet sein. Die eigentliche LED kann hestellungsmäßig noch eine eigene, integrierte, vorgeschaltete kleine Linse besitzen. Die vorbeschriebene Primärlinse bzw. Primäroptik hat mit dieser kleinen Linse nichts zu tun. Insgesamt bildet die Primärlinse bzw. Primäroptik zusammen mit der davor befindlichen Linsenscheibe das optische System.A preferred development proposes according to claim 6, that before each of the LEDs, a so-called primary lens or primary optics is arranged, which is preferably a convergent lens. This primary lens is rotationally symmetrical and may be designed, for example, essentially as a spherical section, in particular substantially hemispherical. The actual LED can hestellungsmäßig still have their own, integrated, upstream small lens. The above-described primary lens or primary optics has nothing to do with this small lens. Overall, the primary lens or primary optics forms the optical system together with the lens disk located in front of it.
Um die Linsenscheibe einfach in dem Gehäuse montieren zu können, schlägt die Weiterbildung gemäß Anspruch 7 vor, daß die Linsenscheibe von der Stirnseite her in das Gehäuse einschiebbar ist.To be able to mount the lens disk simply in the housing, proposes the development according to
