LUMINAIRE

To provide a luminaire capable of allowing an operator to perform an operation for regulating rotation of a lighting fixture easily.SOLUTION: A luminaire 100 includes a lighting fixture 110, a support part 120, and a rotation regulation part 130. The rotation regulation part 130 includes: a screw 131 which is an operation member operable from a lower side of a ceiling 10; and an action member 133 for regulating rotation of the lighting fixture 110 by acting on a spherical surface 114A of the lighting fixture 110 being interlocked with the operation with respect to the screw 131. Therefore, the operation for regulating the rotation of the lighting fixture 110 can be performed from the lower side of the ceiling 10 which is an installation object of the luminaire 100, that is, from a radiation direction side of illumination light P. Therefore, the operation for regulating the rotation of the lighting fixture 110 can be performed easily. A head 131A of the screw 131, in particular, is operated being positioned on the lower side of a flange 123 which is mounted on the ceiling 10. Therefore, the operation for regulating the rotation of the lighting fixture 110 can be performed easily.SELECTED DRAWING: Figure 1 【課題】作業者が灯具の回転を規制する操作を容易に行うことができる照明装置を提供する。【解決手段】照明装置１００は、灯具１１０、支持部１２０、及び、回転規制部１３０を備える。回転規制部１３０は、天井１０の下方側から操作可能な操作部材であるネジ１３１と、ネジ１３１に対する操作に連動して灯具１１０の球面１１４Ａに作用して灯具１１０の回転を規制する作用部材１３３と、を備える。従って、灯具１１０の回転の規制のための操作を照明装置１００の取り付け対象である天井１０の下方側、つまり、照明光Ｐの照射方向側から行うことができる。このため、灯具１１０の回転の規制のための操作を容易に行うことができる。特に、ネジ１３１の頭１３１Ａは、天井１０に取付けられるフランジ１２３の下方側に位置して操作される。従って、灯具１１０の回転の規制のための操作を容易に行うことができる。【選択図】図１
