Abstract

547,661. Lamps having trough-shaped reflectors. STEVENS, A. H. (Electronic Laboratories, Inc.). March 18, 1942, No. 3627. [Classes 75 (ii) and 75 (iv)] An oval-sectioned fluorescent or other tubular lamp. 3 is mounted in sockets at the opposite ends of a trough-shaped reflector 1 having a V-shaped projection 4 along its middle line, the lamp contacts being so arranged that the thin edge of the lamp is directed toward the apex of the projection so as to offer the minimum obstruction to the reflected rays.
