<P>PROBLEM TO BE SOLVED: To provide a lens, a lens unit and a lighting fixture capable of irradiating light from a long and slender rectangle irradiation surface while efficiently using light emitted from a light source. <P>SOLUTION: This lens is provided with reflecting surfaces 1a, 1b, 1c, 1d, 1e radially reflecting the light emitted from the light source in which a main optical axis L is extended in a vertical direction in a direction perpendicular to the main optical axis L of the light source, a reflecting surface 2 reflecting horizontal light LA reflected to the right by the reflecting surface 1a to the front side, a reflecting surface 3 reflecting horizontal light LB reflected to the left by the reflecting surface 1b to the front side, reflecting surfaces 4, 4 reflecting horizontal light LC reflected to the right rear side by the reflecting surface 1c to the front side, reflecting surfaces 5, 5 reflecting horizontal light LD reflected to the left rear side by the reflecting surface 1d to the front side, and an irradiation part having rectangle irradiation surfaces 6A, 6B, 6C, 6D wherein width in a vertical direction is narrow and width in a lateral direction is wide. <P>COPYRIGHT: (C)2007,JPO&INPIT |
