PROBLEM TO BE SOLVED: To provide a luminaire having less color shading and luminance unevenness, and easily controlling light distribution.SOLUTION: A luminaire includes: a light guide handle 40 that includes an emission surface 42, and in which a plurality of light guides 50 is bundled, the light guide including individual emission surfaces of a polygon dividing the above emission surface into plural ones, formed into a columnar shape and having a side surface 53 as a reflection surface 54; a light-emitting matrix 30 that has a plurality of semiconductor light-emitting devices 31 arranged so as to face individual incident surfaces 51 of the light guides respectively; and a control unit 60 that turns individual or grouped semiconductor light-emitting devices of the light-emitting matrix on/off.SELECTED DRAWING: Figure 1 |
