Abstract

548,776. Tubular fluorescent lamp fittings. THORPE, Ltd., F. W., THORPE, F. W., and BRANGWIN. K. C. July 23, 1941, No. 9280. [Classes 75 (iii) and 75 (iv)] Tubular fluorescent lamps C are supported at both ends of an inverted trough-shaped reflector A by a plate 21 adjustably secured by screws 27 and clamping plates 26 to an aperture plate 13 forming the body of a bracket 6 depending from the top of the reflector. The lamp passes through a hole 21a in the plate 21 and is lightly gripped by springs 24. A chamber for the detachable lamp connectors 9 is formed between the bracket 6 and a bracket 7 by a detachable cover 10. A channel 5 extending along the top of the reflector accommodates the lamp leads.
