Description
Die Erfindung betrifft eine Deckenleuchte mit Entblendungsvorrichtung nach dem Oberbegriff des Anspruchs 1 .The invention relates to a ceiling light with anti-glare device according to the preamble of claim 1.
Es sind insbesondere für Großraumbüros mit Bildschirmarbeitsplätzen bereits sogenannte Spiegelrasterleuchten bekannt, die verhindern, daß das von der Lampe ausstrahlende Licht in bestimmten, von der Vertikalen abweichenden großen Ausstrahlwinkeln blendet.So-called mirror grid lights are already known, particularly for open-plan offices with computer workstations, which prevent the light emitted by the lamp from causing glare at certain large beam angles that deviate from the vertical.
Durch diese Spiegelrasterleuchten entsteht jedoch kein heller Raumeindruck, der erleuchtete Raum wirkt verändert, fast höhlenartig.However, these mirror grid lights do not create a bright spatial impression; the illuminated room appears different, almost cave-like.
•r-4 ■: :•r-4 ■: :
Ir vielen Räumen, vor allem in Großraumbüros, ist ein sogenanntes Klimaraster in bestimmtem Abstand unterhalb der Leuchten angebracht, welches unter anderem zur Entblendung der Deckenleuchten dient. Diese Klimaraster erfüllen im allgemeinen nicht die vorgeschriebenen Normen zur Blendungsbegrenzung der Beleuchtung von Räumen mit Bildschirmarbeitsplätzen. üoerhalb eines bestimmten Orenzausstrahlwinkels darf eine maximale Leuchtdichte nicht überschritten werden. Um diese Forderung zu erfüllen, müßte das Klimaraster eine sehr enge Teilung haben. Dadurch würde cäin unnatürlicher Raumeindruck mit .sehr wenig Streulicht entstehen. Außerdem beeinträchtigt ein so enges Klimaraster die Klimatisierung des Raumes.In many rooms, especially in open-plan offices, a so-called climate grid is installed at a certain distance below the lights, which serves, among other things, to reduce glare from the ceiling lights. These climate grids generally do not meet the prescribed standards for limiting glare in the lighting of rooms with computer workstations. A maximum luminance must not be exceeded outside a certain limit beam angle. In order to meet this requirement, the climate grid would have to have a very narrow pitch. This would create an unnatural impression of space with very little scattered light. In addition, such a narrow climate grid impairs the air conditioning of the room.
Aufgabe der Erfindung ist es daher, eine Deckenleuchte mit Entblendungsvorrichtung zu schaffen, wobei die Entblendungsvorrichtung die Entblendungsanforderungen an Bildschirmarbeitsplätze mit oder ohne Klimadecken unter Beibehaltung eines hellen Raumeindrucks erfüllen sollen.The object of the invention is therefore to create a ceiling light with an anti-glare device, wherein the anti-glare device should meet the anti-glare requirements for computer workstations with or without ventilated ceilings while maintaining a bright room impression.
Die Aufgabe wird erfindungsgemäß bei einer Deckenleuchte mit Entblendungsvorrichtung der eingangs genannten Art durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.The object is achieved according to the invention in a ceiling light with anti-glare device of the type mentioned at the outset by the characterizing features of claim 1.
Die Abblendstreifen entblenden die Deckenleuchte bei großen Ausstrahlwinkeln in Bezug auf die Vertikale.The anti-glare strips reduce glare from the ceiling light at large beam angles in relation to the vertical.

Da die Abblendsireifen lichtdurchlässig sind, bleibt ein heller Raumeindruck erhalten.Besonders geeignet ist die erfindungsgemäße Deckenleuchte mit Entblendungsvorrichtung für Bildschirmarbeitsplätze, da sie verhindert, daß sich die Deckenleuchte oder Dünstiges zu helles Streulicht in den Bildschirmen spiegelt und den Betrachter blendet. Since the anti-glare tires are translucent, a bright impression of the room is maintained. The ceiling light with anti-glare device according to the invention is particularly suitable for computer workstations, since it prevents the ceiling light or dim, overly bright scattered light from being reflected in the screens and blinding the viewer.
Die Unteransprüche betreffen vorteilhafte Ausgestaltungen der Erfindung.The subclaims relate to advantageous embodiments of the invention.
Durch eine Ausgestaltung nach Anspruch 2 oder 3 soll gewährleistet werden, daß das durch die Abblendstreif en hindurchtretende Licht gestreut wird.An embodiment according to claim 2 or 3 is intended to ensure that the light passing through the anti-dazzle strips is scattered.
Eine Ausgestaltung nach Anspruch 4 soll ermöglichen, daß der Abblendstreifen je nach den Anforderungen an die Entblendung für große Ausstrahlwinkel eingestellt werden kann und dadurch die vorgeschriebenen Werte für die Leuchtdichte nicht überschritten werden.An embodiment according to claim 4 is intended to enable the anti-glare strip to be adjusted depending on the requirements for glare control for large beam angles and thus the prescribed values for luminance are not exceeded.
Die Ausführungsform nach Anspruch 5 läßt sich besonders formschön und stabil herstellen.The embodiment according to claim 5 can be manufactured in a particularly shapely and stable manner.
Nach Anspruch 6 weisen die Abblendstreifen abgewinkelte Schenkel auf, welche die Entblendungswirkung erhöhen.According to claim 6, the anti-glare strips have angled legs, which increase the anti-glare effect.
Die Ansprüche 7 bis 10 betreffen vorteilhafte Einrichtungen zur Anbringung der Entblendungsvorrichtung.Claims 7 to 10 relate to advantageous devices for attaching the anti-glare device.
Die Ansprüche 11 und 12 legen eine vorteilhafte G-der Entblendungsvorrichtung bzw. der Abblendstreifen fest.Claims 11 and 12 define an advantageous design of the anti-glare device and the anti-glare strips, respectively.

Die Figur zeigt eine perspektivische Schrägansicht der Deckenleuchte mit Entblendungsvorrichtung, von unten gesehen.The figure shows a perspective oblique view of the ceiling light with anti-glare device, seen from below.
Unterhalb einer Leuchtstofflampe 26 ist in geringem Abstand ein Parabolraster 10 angeordnet, an dessen Längsseiten 12 je ein Abblendstreifen 14 aus Plexiglas angeordnet ist. Strichpunktiert ist eine andere Ausführungsform der Abblendstreifen gezeigt,.die mit 14· bezeichnet ist und an jedem Längsrand abgewinkelte Schenkel 18 aufweist. Die Oberfläche der Abblendstreifen 14,14' weist eine Prismenstruktur 16 auf. Das Parabolraster 10 ist über Anfnahmeleisten 20 aus Aluminium mit den Abblendstreifen 14,14* scharnierartig verbunden. Die gesamte Entblendungsvorrichtung 10-22 ist mit Befestigungseinrichtungen 22 an Fassungshaltern 24 der Leuchtstofflampe 26 befestigt, welche ihrerseits an einer Raumdecke 30 festgelegt sind.A parabolic grid 10 is arranged at a short distance below a fluorescent lamp 26, on whose long sides 12 a glare strip 14 made of Plexiglas is arranged. Another embodiment of the glare strips is shown in dash-dotted lines, which is designated 14· and has angled legs 18 on each long edge. The surface of the glare strips 14, 14' has a prism structure 16. The parabolic grid 10 is connected to the glare strips 14, 14* in a hinged manner via aluminum support strips 20. The entire glare control device 10-22 is attached with fastening devices 22 to socket holders 24 of the fluorescent lamp 26, which in turn are fixed to a room ceiling 30.
