Abstract
Die Erfindung betrifft eine Leuchte mit einer an einem Grundkörper (3) angeordneten Lichtquelle, einem Hauptreflektor (4) und mehreren an dem Hauptreflektor (4) getrennt verstellbar angeordneten Sekundärreflektoren (10), wobei der Hauptreflektor (4) einen Reflektorboden (5) und einen Reflektorkörper (6) enthält. Die Lichtquelle ist erfindungsgemäß als LED-Modul (9) ausgebildet und auf dem LED-Modul (9) ist eine Linse (16) zur Umlenkung des von dem LED-Modul (9) abgestrahlten Lichts auch auf die in der Nähe des Reflektorbodens (5) liegenden Bereiche des Reflektorkörpers (6) angeordnet.The invention relates to a luminaire with a main body (3) arranged light source, a main reflector (4) and a plurality of the main reflector (4) separately adjustable arranged secondary reflectors (10), wherein the main reflector (4) has a reflector base (5) and a Reflector body (6) contains. The light source according to the invention is designed as an LED module (9) and on the LED module (9) is a lens (16) for deflecting the light emitted by the LED module (9) also on the light in the vicinity of the reflector base (5 ) lying areas of the reflector body (6).
Description
Die Erfindung betrifft eine Leuchte nach dem Oberbegriff des Anspruchs 1.The invention relates to a luminaire according to the preamble of
Aus der
Die
Aufgabe der Erfindung ist es, eine Leuchte der eingangs genannten Art zu schaffen, die eine energiesparende und dennoch effiziente Beleuchtung ermöglicht.The object of the invention is to provide a luminaire of the type mentioned, which allows energy-saving, yet efficient lighting.
Diese Aufgabe wird durch eine Leuchte mit den Merkmalen des Anspruchs 1 gelöst. Zweckmäßige Ausgestaltungen und vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by a luminaire with the features of
Bei der erfindungsgemäßen Leuchte ist die Lichtquelle als LED-Modul mit mehreren auf einem Träger angeordneten LEDs ausgeführt. Derartige Lichtquellen weisen eine besonders hohe Lebensdauer und hohe Lichtausbeute bei kleinerem Strombedarf und geringerer Wärmeentwicklung im Vergleich zu konventionellen Lichtquellen auf. Allerdings stellen solche LED-Module einen lambertschen Strahler mit einer im Wesentlichen nach einer Seite gerichteten Ausstrahlrichtung dar. Um das durch das LED-Modul abgestrahlte Licht auch auf die Sekundärreflektoren zu fokussieren, ist auf dem LED-Modul eine Linse zur Umlenkung des von dem LED-Modul abgestrahlten Lichts auch auf die in der Nähe des Reflektorbodens liegenden Bereiche des Reflektorkörpers angeordnet ist. Von den in der Nähe des Reflektorbodens liegenden Bereichen des Reflektorkörpers kann das Licht auf die Reflektorflächen der Sekundärreflektoren gerichtet werden. Zur Erreichung der gewünschten Lichtverteilung weist Linse die Form eines Bechers mit einem umlaufenden Rand auf, dessen Außenseite mehrfach abgestuft ist und mehrere übereinanderliegende Schrägflächen enthält In einer besonders kompakten und platzsparenden Bauweise kann das LED-Modul als sogenannte Chip an Board (COB) LED ausgeführt sein, bei der mehrere einzelne LED-Chips auf einer Leiterplatte angebracht sind. Die Chipanschlüsse und die Leiterplatte sind durch Drahtbonding miteinander verbunden und der Chip wird dann durch Epoxidharz abgedeckt und geschützt. Die COB-Technologie erlaubt hohe LED-Packungsdichten, so dass mehr Licht aus einer kleineren Fläche abgestrahlt werden kann. Außerdem ist eine sehr flache und platzsparende Bauweise erreichbar.In the luminaire according to the invention, the light source is designed as an LED module with a plurality of LEDs arranged on a carrier. Such light sources have a particularly long service life and high light output with lower power consumption and lower heat development compared to conventional light sources. However, such LED modules represent a lambertian radiator with a substantially directed to one side beam direction. In order to focus the radiated by the LED module light on the secondary reflectors, is on the LED module, a lens for deflecting the of the LED Module radiated light is also disposed on the lying in the vicinity of the reflector base areas of the reflector body. From the lying in the vicinity of the reflector base areas of the reflector body, the light can be directed to the reflector surfaces of the secondary reflectors. To achieve the desired light distribution lens has the shape of a cup with a peripheral edge, the outside of which is multi-stepped and contains several superimposed inclined surfaces In a particularly compact and space-saving design, the LED module can be designed as a so-called chip on board (COB) LED in which several individual LED chips are mounted on a printed circuit board. The chip terminals and the circuit board are connected by wire bonding and the chip is then covered by epoxy resin and protected. The COB technology allows high LED packing densities so that more light can be emitted from a smaller area. In addition, a very flat and space-saving design can be achieved.
Der Boden der Linse kann eine zentrale, konvexe Wölbung und mehrere zur Wölbung konzentrische, ringförmige Vorsprünge mit einem keilförmigen Querschnitt enthalten.The bottom of the lens may include a central convex curvature and a plurality of domed concentric annular projections of a wedge-shaped cross-section.
Die Linse kann z. B. über eine Schnappverbindung abnehmbar an einem Adapterring des Grundkörpers befestigt sein.The lens can z. B. be attached via a snap connection detachably attached to an adapter ring of the body.
Die Sekundärreflektoren sind zweckmäßigerweise an einer an der Innenseite des Reflektorkörpers befestigten Halterung in alle Richtungen schwenkbar angeordnet. Die Sekundärreflektoren können je nach Einsatzbereich eine konkave, konvexe oder gerade Reflektorfläche aufweisen. Dadurch können unterschiedliche Lichteffekte erzielt werden.The secondary reflectors are expediently arranged pivotably in all directions on a holder fastened to the inside of the reflector body. Depending on the area of use, the secondary reflectors can have a concave, convex or even reflector surface. As a result, different lighting effects can be achieved.
