To provide a luminaire capable of widening the angle of the light only in a desired direction.SOLUTION: A luminaire 1 includes: a first type light source 21; a first shade part 31 for defining an irradiation range of the light radiated from the first type light source 21; a second type light source 22 for radiating light in the same direction as the first type light source 21; and a second shade part 32 for defining an irradiation range of the light radiated from the second type light source 22. The first shade part 31 has a notch part 311. The notch part 311 is formed in such a manner that a directivity angle of the light from the first type light source 21 becomes wider compared with a directivity angle of a portion in which the notch part 311 in the first shade part 31 is not formed.SELECTED DRAWING: Figure 2

    【課題】所望の方向のみの光を広角にすることのできる照明装置を提供する。【解決手段】照明装置1において、一種光源21と、第一種光源21から照射される光の照射範囲を定める第一セード部31と、第一種光源21と同方向に光を照射する第二種光源22と、第二種光源22から照射される光の照射範囲を定める第二セード部32と、を備える。第一セード部31は、切欠部311を有する。切欠部311は、第一セード部31における切欠部311の形成されていない部分の指向角に比して、第一種光源21からの光の指向角が広角となるよう形成されている。【選択図】図2
