LIGHTING FIXTURE

PROBLEM TO BE SOLVED: To provide a lighting fixture which can emit both the light of light emitted from a main surface which is mainly emitted in an upper direction, and light which is emitted in a lower direction.SOLUTION: A lighting fixture comprises: a light guide plate 30 having a first curved part 31 which is protrusively curved upwardly, and a second curved part 32 which is protrusively curved downwardly, formed larger in curvature than the first curved part 31, and arranged by being connected to a lower part of the first curved part 31, or arranged integrally therewith; and a light source which is arranged at one or both of a first end of the first curved part and a second end of the second curved part 32. The light guide plate 30 emits the light of the light source which is made incident from the first end and the second end from main surfaces of the first curved part 31 and the second curved part 32. 【課題】主面から出射する光が主として上方方向へ出射する光と下方方向へ出射する光と両方の光を出射することができる照明器具を提供する。【解決手段】上方に凸状に湾曲する第１湾曲部３１と、下方に凸状に湾曲し、前記第１湾曲部３１よりも曲率が大きく形成され、かつ前記第１湾曲部３１の下方に接続して又は一体に配置される第２湾曲部３２と、を有する導光板３０と、前記第１湾曲部３１の第１端部及び前記第２湾曲部３２の第２端部の一方又は両方に配置される光源と、を備え、前記導光板３０は、前記第１端部及び前記第２端部から入射された前記光源の光を前記第１湾曲部３１及び前記第２湾曲部３２の主面から出射する。【選択図】図１
