Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Den Gegenstand der Erfindung bildet ein Glasreflektor derjenigen Art, wie sie in der amerikanischen Patentschrift 775741 beschrieben sind. Dieser Reflektor ist außen mit strahlenförmig von oben nach unten verlaufenden, allmählich nach unten vergrößerten Prismen ausgestattet, welche das Licht verteilen, während die Innenfläche glatt gehalten ist. Auf der Außenseite befindet sich ein reflektierender Überzug von lichtdurchlässigem Glase, beispielsweise aus Matt- oder Milchglas, oder sonstigem lichtdurchlässigem Material. Der Reflektor selbst sowie die Prismen sind 'aus durchsichtigem Glase hergestellt.The object of the invention forms a glass reflector of the type as it is in American patent 775741 are described. This reflector is outside with radiating from top to bottom, gradually enlarged downwards Equipped with prisms that distribute the light while keeping the inner surface smooth is. On the outside there is a reflective coating of translucent Glass, for example made of frosted or frosted glass, or other translucent material. The reflector itself and the prisms are made of transparent glass.

Es hat sich nun in der Praxis herausgestellt , daß: eine weit vorteilhaftere Lichtverteilung stattfindet, wenn man den lichtdurchlässigen Überzug auf der glatten Innenfläche des Reflektors aufbringt. Hierdurch wird erzielt, daß der Reflektor einen Teil des Lichtes unmittelbar zurückwirft, während diejenigen Lichtstrahlen, welche durch den Reflektor hindurchgehen, von den Prismen wieder zurückgeworfen werden, so daß derIt has now been found in practice that: a far more advantageous light distribution takes place when you put the translucent coating on the smooth inner surface of the reflector. This ensures that the reflector is a part of the light immediately reflects back, while those rays of light which pass through the Go through the reflector, be thrown back by the prisms, so that the

a5 Reflektor sozusagen eine Doppelwirkung hat, wodurch die Lichtdiffusion eine sehr vollkommene wird. a 5 reflector has a double effect, so to speak, whereby the light diffusion is very perfect.

Auf der Zeichnung ist der Reflektor in Fig. ι in Seitenansicht, teilweise im Schnitt, und in Fig. 2 in wagerechtem Schnitt dargestellt.In the drawing, the reflector is in Fig. Ι in side view, partially in section, and shown in Fig. 2 in a horizontal section.

Der aus durchsichtigem Glase hergestellte Reflektor α ist außen mit Prismen b versehen, während die glatte innere Fläche mit dem lichtdurchlässigen, reflektierenden Überzug c aus Matt- oder Milchglas oder sonstigetn reflektierenden Material versehen ist. The reflector α made of transparent glass is provided on the outside with prisms b , while the smooth inner surface is provided with the translucent, reflective coating c made of frosted or frosted glass or other reflective material.

Die Reflektoren können auch teilweise gefärbt werden, wodurch sehr schöne Lichtwirkungen erzielt werden.The reflectors can also be partially colored, creating very nice lighting effects be achieved.
