BeschreibungDescription
Die Erfindung betrifft eine Stehleuchte, insbesondere zur Ausleuchtung von Bildschirmarbeitsplätzen.The invention relates to a floor lamp, in particular for illuminating computer workstations.
Bei Bildschirmarbeitsplätzen trifft man vielfach Arbeitstische an, die in Zweiergruppen angeordnet sind. Verbreitet ist eine L-förmige Anordnung von Schreibtisch oder Ablageplatte einerseits und Arbeitstisch mit Monitor und Tastatur andererseits. Daneben sind in Längsrichtungen nebeneinander angeordnete Arbeitstische sowie Kopf-an-Kopf Anordnungen gebräuchlich. Gefordert wird eine blendfreie Ausleuchtung der Arbeitsplätze. Ferner sollte eine in modernen Büros eingesetzte Leuchte zur Raumausleuchtung beitragen und sich durch eine dekorative Lichtwirkung auszeichnen.At computer workstations, you often find work tables arranged in groups of two. An L-shaped arrangement of a desk or storage shelf on the one hand and a work table with a monitor and keyboard on the other is common. Work tables arranged lengthways next to each other and head-to-head arrangements are also common. Glare-free lighting of the workstations is required. Furthermore, a lamp used in modern offices should contribute to the lighting of the room and be characterized by a decorative lighting effect.
Der Erfindung liegt die Aufgabe zugrunde, eine Stehleuchte für eine Zweiergruppe von Arbeitstischen anzugeben, die eine blendfreie Ausleuchtung der beiden innerhalb der Zweiergruppe beliebig ausrichtbaren Arbeitstische gewährleistet und außerdem zur Raumausleuchtung beiträgt.The invention is based on the object of specifying a floor lamp for a group of two work tables, which ensures glare-free illumination of the two work tables, which can be freely aligned within the group of two, and also contributes to the room illumination.
5 Gegenstand der Erfindung und Lösung dieser Aufgabe ist eine Stehleuchte mit Ständer, auf dem Ständer aufgesetztem Querholm und zwei an dem Querholm befestigten Leuchtenköpfen, wobei die Leuchtenköpfe mindestens eine längliche Lichtquelle, Seitenreflektoren, einen lichtdurchlässigen 0 Boden und eine oberseitige Prismenglasabdeckung aufweisen5 The subject of the invention and the solution to this problem is a floor lamp with a stand, a crossbar mounted on the stand and two lamp heads attached to the crossbar, the lamp heads having at least one elongated light source, side reflectors, a translucent 0 base and a prism glass cover on the top
und an ihrem einen längsseitigen Ende um eine vertikale Drehachse schwenkbar an den Querholm angeschlossen sind. Die Leuchtenköpfe sind um zumindest 180° in der Horizontalen schwenkbar. Dadurch sind sie in jedem beliebigen Winkel zueinander ausrichtbar. Als Lichtquellen sind Kompakt-Leuchtstofflampen bevorzugt. Der lichtdurchlässige Boden ist beispielsweise als Lochboden oder Lamellenboden ausführbar. Das Licht tritt teils direkt und teils an den Seitenreflektoren gebündelt blendfrei nach unten aus. Ferner wird durch die Prismenglasabdeckung Streulicht nach oben abgegeben, welches zur Raumausleuchtung beiträgt.and are connected to the crossbar at one of their long ends so that they can be pivoted around a vertical axis of rotation. The lamp heads can be pivoted horizontally by at least 180°. This means that they can be aligned at any angle to each other. Compact fluorescent lamps are preferred as light sources. The translucent base can be designed as a perforated base or slatted base, for example. The light is emitted downwards, partly directly and partly bundled on the side reflectors, without glare. In addition, the prism glass cover emits scattered light upwards, which helps to illuminate the room.
In weiterer Ausgestaltung lehrt die Erfindung, daß die Leuchtenköpfe einen abnehmbaren, transluszenten Kunststoffkörper aufweisen, der als Schubteil ausgebildet ist und die Prismenglasabdeckung sowie den lichtdurchlässigen Boden an den Längsseiten sowie der zur Drehachse abgewandten Stirnseite randseitig umfaßt. Vorzugsweise besteht der Kunststoffkörper aus einem satiniertenIn a further embodiment, the invention teaches that the lamp heads have a removable, translucent plastic body which is designed as a sliding part and encloses the prism glass cover and the translucent base on the long sides and the edge of the front side facing away from the axis of rotation. Preferably, the plastic body consists of a satin-finished
Polymethacrylat, auch Acrylglas genannt (UllmannsPolymethacrylate, also called acrylic glass (Ullmanns
Encyklopädie der technischen Chemie, 4. Auflage 1980, BandEncyclopedia of technical chemistry, 4th edition 1980, volume
ätk 19, Seiten 22-26). An der Prismenglasabdeckung gestreutes ätk 19, pages 22-26). Scattered light from the prism glass cover
Licht tritt durch die auf der Prismenglasabdeckung aufliegenden Ränder des Kunststoffkörpers in den Kunststoffkörper ein. Dort wird das Licht geleitet und tritt an den wandseitigen Flächen leicht diffus mit von oben nach unten abnehmender Beleuchtungsstärke aus. Nach bevorzugter Ausführung der Erfindung enthält der transluszente Kunststoffkörper eine austauschbare EinlageLight enters the plastic body through the edges of the plastic body resting on the prism glass cover. The light is guided there and emerges from the wall-side surfaces in a slightly diffused manner with the illuminance decreasing from top to bottom. According to a preferred embodiment of the invention, the translucent plastic body contains a replaceable insert
aus einem farbigen Materialstreifen. Durch Austausch des hinterlegten Materialstreifens sind unterschiedliche
Farbgebungen möglich und die optische Wirkung der Stehleuchte an die Raumgestaltung anpaßbar.
5made of a colored strip of material. By replacing the underlying strip of material, different colors are possible and the optical effect of the floor lamp can be adapted to the room design.

Eine ästhetisch besonders ansprechende Gestaltung ergibt sich ferner, wenn das der Drehachse zugeordnete Ende des Leuchtenkopfes als lichtundurchlässiges Gehäuse gestaltet ist, dessen Außenkontur an die Form des transluszenten Kunststoffkörpers angepaßt ist.A particularly aesthetically pleasing design is also achieved if the end of the lamp head associated with the axis of rotation is designed as an opaque housing whose outer contour is adapted to the shape of the translucent plastic body.
