PROBLEM TO BE SOLVED: To provide a luminaire which can illuminate a footing efficiently while preventing an occupant from feeling glare and which can secure sufficient design property (ornamental design property).SOLUTION: A luminaire comprises: a primary light source 12; a light guide plate 11 for making an outgoing light of the primary light source 12 enter the light guide plate from an incidence plane, making the outgoing light transmit inside of the light guide plate then emitting the outgoing light from an outgoing plane; and a design part 19 which is held by the outgoing plane side of the light guide plate 11, and transmits and emits the outgoing light of the light guide plate 11. The outgoing light L1 from the light guide plate 11 is made to transmit the design part 19 and is emitted, by directivity in which, a direction which is obliquely inclined to a direction of internal transmission from a normal direction of the outgoing plane of the light guide plate 11 is a main outgoing direction of the outgoing light.SELECTED DRAWING: Figure 5

    【課題】搭乗者にまぶしさを感じさせないようにして足元等を効率良く照明することができ、かつ充分なデザイン性(意匠性)をも確保できるようにする。【解決手段】一次光源12と、一次光源12の出射光を入射面より入射して内部伝搬しながら出射面より出射する導光板11と、導光板11の出射面側に保持されて、導光板11の出射光を透過して出射する意匠部19とを備え、導光板11の出射面の法線方向から内部伝搬の方向に斜めに傾いた方向が主たる出射光の出射方向となる指向性により、導光板11からの出射光L1を意匠部19を透過して出射する。【選択図】図5
