PROBLEM TO BE SOLVED: To suppress illuminance irregularity of an irradiation field from a luminaire.SOLUTION: A luminaire includes: a COB where a plurality of light-emitting chips respectively emitting light is arranged with intervals on a circuit board; and a reflector which has a plurality of reflection surfaces reflecting light from the COB and in which parts of a reflection images formed by the plurality of reflection surfaces are overlapped to each other and projected. In the COB, since the reflection images formed by the plurality of reflection surfaces are overlapped, the plurality of light-emitting chips is arranged so that contrast difference between reflection images B1a, B1b of the light-emitting chips and reflection images B2a, B2b of the intervals is reduced. |
