Abstract: There is disclosed a light guide for guiding light from a light source in a longitudinal direction and radiating the light to illuminate an object to be illuminated, which comprises a diffuser for diffusing the light from the light source along the longitudinal direction of the light guide, and a radiator for radiating the light diffused by the diffuser in a predetermined direction. By arranging the diffuser and the radiator so that a normal line passing through the center of the width of the diffuser is different from the predetermined direction at least in the vicinity of the light source when viewed in the longitudinal direction of the light guide, the illuminance distribution of the longitudinal direction of the light guide is uniformed.

Abstract: A coating film 9 is formed on a light guide-mounting portion of a frame 2. This coating film 9 presents a color reflecting light over a wide range of wavelength such as a white color. Instead of forming the coating film 9, a light guide 3 can also be mounted through a thin paper-shaped member such as a white-colored paper or a silver-colored paper that allows light to reflect. The coating film or the thin paper-shaped member can be provided not only on the bottom surface of the light guide-mounting portion of the frame 2, but also on the side thereof.
