<P>PROBLEM TO BE SOLVED: To obtain uniform lighting by suppressing generation of shadows caused by prism shape due to the level difference installed in a light guide body. <P>SOLUTION: The lighting system is provided with a light source 1 to emit light and a light guide body 2 which has a light incident face 2a to make light from the light source 1 enter, a reflection part 3 to reflect the light incident through the light incident face 2a, and an illumination part 4 which illuminates by emitting the light reflected at the reflection part 3. The reflection part 3 is formed at the wall face in the vicinity of the illumination part 4 of the light guide body 2 and has a plurality of level difference parts 3b which change in a step shape in a longitudinal direction, and has a plurality of recessed parts 3c formed in a curved surface arranged in the longitudinal direction of the standing wall parts of the level difference parts 3b. <P>COPYRIGHT: (C)2012,JPO&INPIT |
