Abstract

560,802. Electric lamp fittings. REVO ELECTRIC CO., Ltd., and REEVES, F. H. Nov. 3, 1942, No. 15449. [Classes 75 (ii) and 75 (iv)] A tubular fluorescent discharge lamp c is mounted in a fitting comprising an open metallic trough band a number of transparent or translucent sections a which are secured to the trough by flexible or resilient metal bands g anchored at one end in jawed brackets e and attached at the other end to toggle-lever tensioned catches j. The inner surface of the trough b forms a reflector for illuminating the ceiling. The upper parts of the sections a may be bulbed outwardly to form diffusing surfaces for illuminating the outer surface of the trough or a gap may be left between the upper edges of the sections and the bottom of the trough. A number of angle clips l are provided below the trough to support the sections a temporarily when the bands g are disconnected or one or more of the sections are to be removed.
