    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 lens unit (U15) includes a housing (45), an upper and a lower lens arrays (A1null, A2null), and a first and a second prisms (4A, 4B). Each of the lens arrays includes a plurality of lenses, a light-shielding member (4), and a plurality of positioning projections, all of which are integral with each other. Downwardly traveling light which enters the housing (45) through a first slit (45c) formed at an upper portion of the housing (45) is directed upward by the first prism (4A) to pass through the two lens arrays (A1null, A2null). The light is then directed downward by the second prism (4B) to exit the housing through a second slit (45d) formed at a lower portion of the housing (45).
