Abstract

Die Erfindung betrifft eine Leuchte mit einem Leuchtengehäuse 10 zur Aufnahme einer Leuchtstofflampe 12, einer Primäroptik 20, die das von der mindestens einen Leuchtstofflampe 12 ausgestrahlte Licht direkt auf eine Sehaufgabe lenkt, und einer Sekundäroptik 40, die das von der Lampe ausgestrahlte Licht über einen oberhalb der Leuchtstofflampe 12 angeordneten Dachreflektor indirekt auf die Sehaufgabe lenkt. Um den von der Leuchtstofflampe 12 abgestrahlten Lichtstrom mittels der Primär- und Sekundäroptik blendfrei mit größtmöglichem Betriebswirkungsgrad in den Raum abzugeben wird erfindungsgemäß vorgeschlagen, dass der Dachreflektor eine konkav gewölbte Hauptreflektionsfläche 44 umfasst, und dass seitlich von dem Dachreflektor mindestens ein Seitenreflektor 60,62 angeordnet ist, der ausgebildet ist, um eine unzulässig hohe Blendung zu vermeiden.

The invention relates to a luminaire with a luminaire housing 10 for accommodating a fluorescent lamp 12, a primary optic 20 which directs the light emitted by the at least one fluorescent lamp 12 directly to a Sehaufgabe, and a secondary optics 40, which emits the light emitted by the lamp via an above the fluorescent lamp 12 arranged roof reflector directs indirectly to the visual task. In order to emit the luminous flux radiated by the fluorescent lamp 12 by means of the primary and secondary optics glare-free with the greatest possible operating efficiency in the room according to the invention proposed that the roof reflector comprises a concave main reflection surface 44, and that at least one side reflector 60,62 is arranged laterally of the roof reflector , which is designed to prevent inadmissibly high glare.
