Abstract
Beleuchtungseinrichtung bestehend aus Umlenkelementen und mehreren LEDs, dadurch gekennzeichnet, daß auf der lichtquellenseitigen Seite des Umlenkelementes ein konvexer Freiformkörper, der auch kegelförmig oder kugelförmig sein kann, als Lichtquellenträger vorhanden ist, auf dem die punktförmig strahlenden LEDs freiformflächig so angeordnet sind, daß der Hauptlichtstrom der LED-Lichtquelle durch Reflexion am Umlenkelement ohne Blendung die Leuchte verlässt.lighting device consisting of deflecting elements and several LEDs, characterized that on the light source side of the deflecting a convex Free-form body which is also cone-shaped or spherical can be as a source of light source is present, on which the punctiform radiating LEDs so free form surface are arranged that the Main luminous flux of the LED light source by reflection at the deflection element without glare leaves the light.
Description
Die Erfindung betrifft eine LED-Reflektorleuchte, die zur mobilen und/oder ortsfesten Verwendung geeignet ist. Das integrierte Leuchtmittel sind vorzugsweise LEDs.The The invention relates to an LED reflector lamp, the mobile and / or stationary use is suitable. The integrated light source are preferably LEDs.
LED-Leuchten sind als architektonische Konstruktionselemente für Gebäude schon seit längerem bekannt. Es gibt auch zum Bodeneinbau geeignete Leuchten und leuchtende Pflastersteine ebenso Downlights und Flächenleuchten. Bei höheren Leuchtdichten gemein ist diesen Leuchten, dass sie stark blenden.LED lights are already considered architectural construction elements for buildings for a long time known. There are also luminaires suitable for ground mounting and luminous ones Paving stones as well downlights and area lights. At higher luminances Common to these lights is that they dazzle strongly.
Der Erfindung liegt die Aufgabe zugrunde, eine einfach aufgebaute Beleuchtungseinrichtung mit LEDs zu schaffen, bei der das von mehreren LEDs erzeugte Licht möglichst gleichmässig ohne Blendung die Leuchte verlässt.Of the Invention is based on the object, a simply constructed lighting device with LEDs to create the light generated by multiple LEDs preferably evenly without glare leaves the light.
Gelöst wird diese Aufgabe erfindungsgemäß durch die Merkmale des Anspruchs 1, Weitere vorteilhafte Anwendungen sind Gegenstand der Unteransprüche.Is solved this task according to the invention by the features of claim 1, further advantageous applications are Subject of the dependent claims.
Die geometrische Form der mindestens einen Lichtquelle, die aus einer Vielzahl frei positionierbarer, oder/und ein Raster oder/und Zeilen bildende, frei strahlende LEDs und/oder OLEDs besteht, ist frei wählbar und entspricht vorzugsweise einer Freiformfläche auf einem bevorzugt konvexen Freiformkörper der auch kegelförmig oder/und kugelförmig sein kann.The geometric shape of at least one light source, which consists of a Variety freely positionable, and / or a grid and / or rows forming, free-radiating LEDs and / or OLEDs is, is freely selectable and preferably corresponds to a free-form surface on a preferably convex Freeform body of the also conical or / and spherical can be.
Durch die vorzugsweise konzentrische Anordnung des konvexen und/oder konkaven Freiformkörpers innerhalb des Umlenkelementes, das ein Reflektor sein kann, und die darauf platzierten, punktförmig strahlenden LEDs, kann deren Hauptlichtstrom direkt oder durch Reflexion am Umlenkelement ohne Blendung die Leuchte verlassen.By the preferably concentric arrangement of the convex and / or concave Free-form body within the deflecting element, which may be a reflector, and the placed on it, punctiform radiating LEDs, their main luminous flux can be directly or by reflection Leave the light on the deflector without glare.
Durch die Gestaltung des Lichtquellenträgers als konkaven oder/und konvexen oder/und kegelförmigen oder/und kugelförmigen Freiformkörper kann die Lichtquellenfläche vergrössert werden ohne die äusseren Abmessungen der Leuchte zu verändern. Die Form der Lichtquelle und die Form des Umlenkelementes, die beide Freiformflächen sein können, können einander so angepasst werden, dass Mehrfachreflexionen weitestgehend vermieden werden.By the design of the light source carrier as a concave and / or convex and / or conical or / and spherical Freeform body can the light source surface increases be without the outward ones To change the dimensions of the luminaire. The shape of the light source and the shape of the deflector, both Free-form surfaces could be, can be adapted to each other so that multiple reflections as much as possible be avoided.
Ein weiterer Vorteil ist die Nutzung zumindest eines Teils des Lichtquellenträgers als Wärmesenke.One Another advantage is the use of at least a portion of the light source carrier as Heat sink.
Werden mehrere Lichtquellen unterschiedlicher Farbe verwendet, bietet es sich an, dass die Intensität und/oder Farbe verändert und diese Veränderung durch eine interne und/oder externe elektronische Steuerung bewirkt wird.Become It uses several light sources of different color that the intensity and / or color changed and this change caused by an internal and / or external electronic control becomes.
Anhand der Zeichnungen wird die Erfindung im Folgenden näher erläutert.Based of the drawings, the invention is explained in more detail below.
