Description
Flache Eckleuchte für Leuchtstofflampen Die Erfindung betrifft eine flache Eckleuchte für Leuchtstofflampen mit einem an einer Decke befestig- baren Gehäuseoberteil, der eine ausserhalb des Lam penraumes befindliche rinnenartige Verformung für die Vorschaltgeräte hat und an dem ein lichtdurchlässiger Gehäuseunterteil gehaltert ist. Es ist eine derartige Leuchte bekannt, deren Gehäuseunterteil aus einem Boden mit einer abgewinkelten Längswand und zwei abschliessenden Querwänden besteht.
Die Halterung eines solchen Gehäuseunterteils ist mit Schwierigkeiten verbunden.
Nach der Erfindung ist eine Verbesserung dadurch erzielt, dass der Gehäuseunterteil die Form einer Wanne mit C-Querschnitt hat, die mit einer Längswand entlang der Verformung für die Vorschaltgeräte, die einen U-Querschnitt hat, angeordnet ist. Bei der erfindungsge mässen Leuchte lässt sich der Gehäuseunterteil ohne Schwierigkeiten am Gehäuseoberteil haltern.
Die Erfindung ist in der Zeichnung beispielsweise dargestellt. Es zeigen: Fig. 1 einen vertikalen Querschnitt der erfindungs- gemässen Leuchte und Fig. 2 eine Ansicht einer am Gehäuseoberteil befe- stigbaren Querwand.
Die abgebildete flache Eckleuchte ist zur Bestückung mit zwei Leuchtstofflampen eingerichtet. Sie enthält einen an einer Decke befestigbaren Gehäuseoberteil 1, der mit einer die ausserhalb des Lampenraums befindli chen Vorschaltgeräte, insbesondere die Drosselspulen 2, aufnehmenden Verformung 3 versehen ist. An dem Ge häuseoberteil 1 ist ein lichtdurchlässiger Gehäuseunter teil 4 gehaltert.
Nach der Erfindung hat der Gehäuseunterteil 4 die Form einer Wanne mit C-Querschnitt, die mit einer Längswand 5 entlang der Verformung 3 für die Vor- schaltgeräte 2 angeordnet ist. Dabei hat die Verformung 3 einen U-Querschnitt. Die Verformung 3 kann in Rich tung zur Decke offen sein. Zur Befestigung des Ge häuseunterteils 4 am Gehäuseoberteil 1 dient ein zwei armiger Innenhebel 6, der mittels eines Aussenhebels 7 bedienbar ist.
Zweckmässig sind an den Schmalseiten des Gehäu seoberteils 1 lichtundurchlässige Querwände 8 (Fig. 2) befestigt, welche die Stirnwände des Gehäuseunterteils 4 teilweise überdecken. Die Querwände können die Stirn wände auch ganz überdecken.
Flat corner luminaire for fluorescent lamps The invention relates to a flat corner luminaire for fluorescent lamps with a top housing part that can be fastened to a ceiling, which has a channel-like deformation for the ballasts located outside the lamp room and on which a translucent housing bottom part is held. Such a lamp is known, the lower housing part of which consists of a floor with an angled longitudinal wall and two closing transverse walls.
The mounting of such a lower housing part is associated with difficulties.
According to the invention, an improvement is achieved in that the lower housing part has the shape of a trough with a C-cross section, which is arranged with a longitudinal wall along the deformation for the ballasts, which has a U-cross section. With the lamp according to the invention, the lower part of the housing can be held on the upper part of the housing without difficulty.
The invention is shown in the drawing, for example. The figures show: FIG. 1 a vertical cross section of the lamp according to the invention, and FIG. 2 a view of a transverse wall that can be fastened to the upper part of the housing.
The flat corner luminaire shown is set up for use with two fluorescent lamps. It contains an upper housing part 1 which can be fastened to a ceiling and which is provided with a deformation 3 which accommodates the ballasts located outside the lamp compartment, in particular the choke coils 2. At the Ge upper housing part 1, a translucent lower housing part 4 is supported.
According to the invention, the lower housing part 4 has the shape of a trough with a C cross-section, which is arranged with a longitudinal wall 5 along the deformation 3 for the ballast 2. The deformation 3 has a U-cross section. The deformation 3 can be open in the direction of the ceiling. A two-armed inner lever 6, which can be operated by means of an outer lever 7, is used to attach the lower housing part 4 to the upper housing part 1.
Expediently, opaque transverse walls 8 (Fig. 2) are attached to the narrow sides of the housings seobteils 1, which partially cover the end walls of the lower housing part 4. The transverse walls can also completely cover the front walls.
