<P>PROBLEM TO BE SOLVED: To provide a lighting system capable of improving uniformity of illuminance on a lighting surface. <P>SOLUTION: The lighting system is provided with a light source part 10 having an emitting surface 12a to emit light and a light distribution control member 20 which has a prism surface 20a including a plurality of prisms 24 that has an inclined surface 25 and is arranged in a plane shape to two-dimensionally control the light distribution of the emitted light from the light source part 10, and the prism surface 20a has flat parts 22. By the light distribution control member 20, the light intensity angle distribution is arbitrarily adjusted in the light distribution characteristics of the illumination light from the lighting system and it has become possible to get close to an ideal distribution for achieving uniform illuminance. <P>COPYRIGHT: (C)2013,JPO&INPIT |
