Abstract

208,309. Pears, C. Oct. 27, 1922. Reflectors; mounting reflectors directly on rods or tubes; securing reflectors to holders. - A troughshaped reflector comprises an open ended truncated conical body 1 of aluminium &c., the narrower end of which merges into a base of reduced diameter. The base, which is preferably flanged as at 7 may be split as at 4 so that it may be sprung open to fit various sizes of lamps, or the opening in the base may be bridged by a flexible extension 2 formed integrally with one side of the reflector, or by an additional flexible strip.
