Abstract

Die vorliegende Erfindung betrifft eine im Umriß rechteckige oder quadratische Deckeneinbauleuchte mit einem Leuchtenraster umfassend lichtlenkende Reflektoren. Anstelle des kastenförmigen Leuchtengehäuses dienen für die längsseitige Begrenzung der Leuchte die äußeren Längsseitenreflektoren (11) und für die querseitige Begrenzung der Leuchte die Endlamellen (14) des Leuchtenrasters. Die Längsseitenreflektoren (11) weisen untere Abkantungen (11a) auf, geeignet zur Auflage auf eine umlaufende Leiste (13) mittels derer die Leuchte (1) in der Deckenöffnung einer abgehängten Decke befestigt wird. Ziel der Erfindung ist es, eine im Umriß rechteckige oder quadratische Deckeneinbauleuchte zu schaffen, bei der die Funktion des kastenförmigen Gehäuses von vorhandenen Teilen der Leuchte übernommen wird, so daß dieses entfallen kann, wodurch eine wesentliche Materialersparnis erzielt wird.

Figure 00000001
The present invention relates to a recessed rectangular or square ceiling light with a luminaire grid comprising light-directing reflectors. Instead of the box-shaped luminaire housing, the outer longitudinal side reflectors (11) serve for the longitudinal limitation of the luminaire and the end lamellae (14) of the luminaire grid for the transverse limitation of the luminaire. The longitudinal side reflectors (11) have lower folds (11a), suitable for resting on a circumferential bar (13) by means of which the lamp (1) is fastened in the ceiling opening of a suspended ceiling. The aim of the invention is to provide a rectangular or square recessed ceiling light in which the function of the box-shaped housing is taken over by existing parts of the light, so that this can be omitted, thereby achieving a substantial saving in material.
