Abstract

Die vorliegende Erfindung betrifft eine Flächenleuchte (1) aufweisend eine flächige LED-Leiterplatte (2) mit einer flächigen Vorderseite (20), auf der eine Vielzahl von LEDs (23) vorgesehen ist, und einer von der Vorderseite (20) abgewandten flächigen Rückseite (21), wobei die Vorderseite (20) und die Rückseite (21) über eine umlaufende Stirnseite (22) miteinander verbunden sind, ein vorderes Lichtabgabeelement (3), welches eine zu der Vorderseite (20) beabstandet vorgesehene vordere Lichtabgabefläche (30) aufweist, die als Diffusor ausgebildet ist und die mit der LED-Leiterplatte (2) einen Lichtraum (4) derart begrenzt, so dass von den LEDs (23) in den Lichtraum (4) abgegebenes Licht wenigstens teilweise direkt über die vordere Lichtabgabefläche (30) nach außen abgegeben wird, und ein hinteres Lichtabgabeelement (5), welches eine hintere Lichtabgabefläche (50) aufweist, die der Rückseite (21) gegenüberliegend auf der dem vorderen Lichtabgabeelement (3) abgewandten Seite der LED-Leiterplatte (2) vorgesehen ist, wobei die LED-Leiterplatte (2) die Vorderseite (20) mit der Rückseite (21) verbindende Lichtdurchtrittsöffnungen (7) derart aufweist, so dass von der vorderen Lichtabgabefläche (30) zum Lichtraum (4) hin reflektiertes Licht der LEDs (23) über die Lichtdurchtrittsöffnungen (7) und die hintere Lichtabgabefläche (50) rückseits der Flächenleuchte (1) nach außen abgegeben wird.
