PROBLEM TO BE SOLVED: To emit light emitted from semiconductor light sources toward positions to be irradiated, and to thin the luminaire body. SOLUTION: This lighting system is provided with a unit main body, a body substrate 2 having a base end part 22 in one direction 2a and the other direction 2b orthogonal to the direction 2a, a central part 23 and a tip part 24, and where a substrate surface 21 is set along the luminaire body, and plural semiconductor light sources 4 emitting light having directivity around an optical axes 41 to positions to be irradiated. The respective semiconductor light sources 4 are aligned along the direction 2a of the body substrate 2, and an angle αis formed between the body substrate surface 21 and the optical axis 41 in the direction 2a. Here, the respective semiconductor light source 4 are arranged on the body substrate 2 such that the angle α varies. |
