Abstract

512,062. Reflectors. HIRSCH, E. Jan. 28, 1938, No. 2785. Drawings to Specification. [Class 75 (ii)] A reflector for producing uniform illumination of a room comprises two or more axially superposed specular and diffuse zones arranged alternately and forming an interiorly reflecting concave surface. The diffuse zones may be dulled, enamelled, or coated with paint. The reflector may be formed from flanged annular stepped sections soldered together and may be of metal or glass.
