Description
Die Erfindung betrifft eine blendfreie Abschirmung @anLängfeldleuchten, Neonröhren oder rährenfünnigen, Beelleuchtungskärpern.The invention relates to a glare-free shielding @ on longitudinal field lights, Neon tubes or five rods, lighting bodies.
Die bekannten gitterförmigen Abschirmungen machten einen Rahmen oder Kasten, einen sog. Reflektor, welcher sich am Beleuchtungskörper befand; erforderlich, wohingegen. die erfindungsgemäßen Abschirmungen auf die in Frage kOmmende Röhre, ganz gleich ob es sich um Einröhren-oder Mehrröhrenlangfeldleuchfien handelt, mittels an der Abschirmung selbst befindlicher Klammern einfach aufgesteckt werden können.The well-known lattice-shaped shields made a frame or Box, a so-called reflector, which was located on the lighting fixture; necessary, whereas. the shields according to the invention on the tube in question, regardless of whether it is single-tube or multi-tube long-field luminaries, by means of clamps located on the shield itself can simply be attached.
Die vollkommene Blendungsfreiheit und ausreichende Beleuchtungsstärke wird durch eine klein quadratisch od. ä., nach Form i, 2, 3 oder q. in Abb. Z, gelochte Abschirmung aus, Kunstharz, Polystyrol, Glas usw. erreicht. In der Zeichnung zeigt .The complete freedom from glare and sufficient illuminance is represented by a small square or the like, according to the form i, 2, 3 or q. in Fig. Z, perforated Shielding made of synthetic resin, polystyrene, glass, etc. is achieved. In the drawing shows .
