<P>PROBLEM TO BE SOLVED: To provide a lighting system capable of improving the uniformity of a luminance distribution by changing a luminous energy distribution of inside propagation light in a light guide member by deflecting light emitted from a light source. <P>SOLUTION: This lighting system 100 has: the light sources 111 and 112; and the light guide member 120 for introducing light emitted from the light sources 111 and 112 from an end face 121 to emit it from a front surface 122; and is formed, inside the end face 121 of the guide member 120 and in a front area in the optical axis direction of the light sources 111 and 112, with reflecting surfaces 124a and 125a capable or reflecting at least a part of the inside propagation light of the guide member 120 in the sideward direction with respect to its incident direction. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
