Abstract

Die Erfindung betrifft eine Leuchte mit einem Leuchtengehäuse (2), einem Leuchtelement (4), beispielsweise in Form mehrerer LEDs (42, 42'), einer Lichtleitplatte und einem Lichtabgabeelement (8). Das Lichtabgabeelement (8) weist eine Lichtabgabefläche (84) auf, durch die eine Flächennormale (N) festgelegt ist. Ein von dem Leuchtelement (4) abgestrahltes Licht wird seitlich in die Lichtleitplatte eingestrahlt und verlässt im Weiteren die Leuchte über die Lichtabgabefläche (84) in Richtung der Flächennormalen (N). Weiterhin weist das Lichtabgabeelement (8) ein Rastelement für eine Rastverbindung (R1) mit dem Leuchtengehäuse (2) auf, wobei, in einer Projektion längs der Flächennormalen (N) betrachtet, das Rastelement vollständig innerhalb des von der Lichtabgabefläche (84) umschriebenen Bereichs (B) angeordnet ist. Durch das derart angeordnete Rastelement lässt sich das Lichtabgabeelement (8) an dem Leuchtengehäuse (2) haltern, ohne dass hierfür ein Rahmenelement um die Lichtabgabefläche (84) herum erforderlich wäre. Dabei lässt sich das Lichtabgabeelement (8) aufgrund der Rastverbindung (R1) besonders einfach mit dem Leuchtengehäuse (2) verbinden.

The invention relates to a luminaire with a luminaire housing (2), a luminous element (4), for example in the form of a plurality of LEDs (42, 42 '), a light guide plate and a light emitting element (8). The light-emitting element (8) has a light-emitting surface (84), by means of which a surface normal ( N ) is defined. A light emitted by the luminous element (4) is radiated laterally into the light-guiding plate and subsequently leaves the luminaire via the light-emitting surface (84) in the direction of the surface normal ( N ). Furthermore, the light-emitting element (8) has a latching element for a latching connection ( R1 ) with the luminaire housing (2), wherein viewed in a projection along the surface normal ( N ), the latching element is completely within the area circumscribed by the light-emitting surface (84) ( B) is arranged. By means of the locking element arranged in this way, the light-emitting element (8) can be held on the luminaire housing (2) without the need for a frame element around the light-emitting surface (84). In this case, the light-emitting element (8) due to the latching connection ( R1 ) particularly easy to connect to the lamp housing (2).
