ABSTRACT:
A light transmitting body (10), (40) has a longitudinal axis (12), (42), and a light radiating surface (14), (46) extending substantially parallel to the axis (12), (42). Where the body is an optical fiber (10), the light radiating surface is the circumferential surface (14) of the fiber (10). Where the body is a rectangular panel (40), the light radiating surface is a rectangular surface (46) of the panel (40). A plurality of striations (16), (44) are formed in the light radiating surface (14), (46) parallel to the axis (12), (42), which cause light entering the body (10), (40) along the axis (12), (42) to be radiated out of the body (10), (40) through the light radiating surface (14), (46) with substantially uniform intensity along the axis (12), (42). The striations (16), (44) may be formed by molding, cold drawing, heating the body (10), (40) under tension, cutting, or by bundling and fusing a plurality of small optical fibers (90) together.
