LIGHT GUIDE BODY, AND LIGHTING SYSTEM EQUIPPED WITH IT

摘要

PROBLEM TO BE SOLVED: To provide a light guide body capable of uniformly irradiating an illuminating object without irregularity; and a lighting system equipped with the light guide body.

SOLUTION: This light guide body 2 is composed by forming, on a main body part formed in a nearly-flat shape, incident surfaces 2a introducing light from point-like light sources 1, reflecting surfaces 2b reflecting the light introduced from the incident surfaces 2a, and an emitting surface 2c emitting the light reflected on the reflecting surfaces 2b to a light entering end surface 3c of the illuminating object 3. The reflecting surface 2b comprises a plurality of prisms P continuously continued in a recessed form with respect to the emitting surface 2c so that luminous flux can be emitted from the emitting surface 2c vertically to the surface at uniform intervals.
