PROBLEM TO BE SOLVED: To prevent the occurrence of a light-dark difference, that is, a light-dark difference between a light region located on an axis of the light source and a location distant from the light source, which is caused while controlling the luminous intensity distribution of a light source by lenses. SOLUTION: A lighting fixture includes a unit 3 with a plurality of lenses 2 enclosing light sources 1, arranged in parallel, and a second lens 5 provided at a front face of the unit 3, that is, on an extension line of an optical axis. The first lenses 2 are integrally formed connected to each other by a diffusion part 4 having a lens cut 13. The diffusion part 4 is formed in arch shape in the unit 3, and an upper face 6 has a lens cut 7. COPYRIGHT: (C)2009,JPO&INPIT
