Abstract

546,442. Electric discharge lamp fittings. EDISON SWAN ELECTRIC CO., Ltd., and' COCKSEDGE, F. M. May 1, 1941, No. 5649. [Classes 75 (ii) and 75 (iv)] A trough - shaped reflector 1 supporting a linear electric discharge lamp is provided on its upper surface with two longitudinal ribs 7 carrying transversely projecting rods 8, 9 by which the reflector is removably supported by fixed hooks 6 and pivoted hooks 5 on an inverted U-shaped casing 3 enclosing the lamp control apparatus. The lamp circuit is completed by the engagement of spring contacts arranged between the ribs 7 with contacts 10 in the casing. The ends of the casing 3 are closed by pivoted doors 12 spaced a sufficient distance from the ribs 7 to allow upward and lateral movements of the reflector during removal and replacement.
