Description
Lampe mit mehreren Refiektoren zur Erzielung einer diffusen Beleuchtung. Der Gegenstand vorliegender Erfindung betrifft eine Lampe zur Erzielung einer diffusen Beleuchtung, bei welcher mehrere übereinanderliegende Reflektoren zur An wendung gelangen, die in verschiedenen Winkeln zur Lichtquelle angeordnet sind.
Auf beiliegender Zeichnung sind einige Ausführungsbeispiele des Erfindungsgegen standes dargestellt, und es veranschaulichen: Fig. 1 eine Ansicht einer Lampe mit im Längsschnitt dargestellten Reflektoren, Fig. 2 eine andere Ausführungsform der Lampe, Fig. 3 eine Glühlampe mit stufenförmig gestaltetem Glasballon zur Auflage der Re flektoren, und Fig. 4 eine weitere Ausführungsform des Erfindungsgegenstandes.
Gemäss der ersten Ausführungsform nach Fig. 1 ist die Glühlichtlampe 7 von einem Glasmantel 4 umgeben, welcher eine treppen artige Form besitzt. Die einzelnen stufenarti gen Absetzungen dieses kegelartigen Glas mantels 4 haben den Zweck, den aus emaillier tem Blech, milehfarbigem Glas mit glat ter Oberfläche oder aus irgend welchem. ge- eignetem reflektierendem Material hergestell ten kreisringförmigen Reflekoren 1, 2 und 3 als Auflage zu dienen. Die halbkugelförmige Schale 5, aus milchfarbigem Glas, wird durch einen klappbaren Ring 6 mit dem Rand des Glasmantels 4 verbunden.
In Fig. 2 sind die Reflektoren 1, 2 und 3 innerhalb eines stufenförmig abgesetzten Glasmantels 4 angeordnet, so dass eine Ver- staubung der einzelnen Reflektoren auf diese Weise verhindert wird.
Fig. 3 zeigt die treppenartige Gestaltung einer Glasbirne, zwecks Auflage der einzel nen Reflektoren. Zwischen Absatz und Re flektor ist eine aus schlecht wärmeleitendem Material bestehende Zwischenlage 10, bei spielsweise aus Asbest, angeordnet, zwecks Verhütung eines Zerspringens der Reflekto ren oder der Glasbirne.
In Fig. 4 ist eine mit einer Hülle 4 aus Glas versehene Ausführungsform veranschau licht, bei welcher die Hülle als Träger für die übereinanderliegenden Reflektoren 1, 2 und 3 dient.
Bei den Ausführungsformen der Lampe nach den Fig. 3 und 4 ist keine Halbkugel 5 vorhanden. In diesen Fällen ist der untere Teil der Lampe geätzt, während der obere Teil aus klarem Glas hergestellt ist.
Bei sämtlichen Ausführungsformen ist die Stellung der Reflektoren eine derartige, dass die einfallenden Strahlen 9 nach unten geworfen werden, so dass neben einer hellen Raumbeleuchtung auch eine intensive Be leuchtung unterhalb der Lampe möglich ist.
Lamp with several reflectors to achieve diffuse lighting. The subject matter of the present invention relates to a lamp for achieving diffuse lighting in which several superimposed reflectors are used, which are arranged at different angles to the light source.
In the accompanying drawings, some embodiments of the subject matter of the invention are shown and illustrate: Fig. 1 is a view of a lamp with reflectors shown in longitudinal section, Fig. 2 is another embodiment of the lamp, Fig. 3 is an incandescent lamp with a stepped glass balloon to support the Re flexors, and FIG. 4 shows a further embodiment of the subject matter of the invention.
According to the first embodiment according to FIG. 1, the incandescent lamp 7 is surrounded by a glass jacket 4 which has a stair-like shape. The individual stufenarti conditions of this cone-like glass jacket 4 have the purpose of enamelled sheet metal, mileh-colored glass with a smooth surface or whatever. suitable reflective material produced circular reflectors 1, 2 and 3 to serve as a support. The hemispherical bowl 5, made of milk-colored glass, is connected to the edge of the glass jacket 4 by a hinged ring 6.
In FIG. 2, the reflectors 1, 2 and 3 are arranged within a stepped glass jacket 4, so that dust on the individual reflectors is prevented in this way.
Fig. 3 shows the staircase-like design of a glass bulb, for the purpose of supporting the individual reflectors. Between paragraph and Re reflector is made of a poorly thermally conductive material intermediate layer 10, for example made of asbestos, arranged in order to prevent the reflector from cracking or the glass bulb.
In Fig. 4 an embodiment provided with a cover 4 made of glass is illustrated, in which the cover serves as a support for the reflectors 1, 2 and 3 lying one above the other.
In the embodiments of the lamp according to FIGS. 3 and 4, no hemisphere 5 is present. In these cases the lower part of the lamp is etched, while the upper part is made of clear glass.
In all of the embodiments, the position of the reflectors is such that the incident rays 9 are thrown downwards, so that, in addition to bright room lighting, intense lighting is possible below the lamp.
