PROBLEM TO BE SOLVED: To provide a luminaire capable of securing heat radiation properties and capable of performing attachment/detachment of a light source unit surely with good operability.SOLUTION: A luminaire includes: a body unit having a locking part 39; and a light source unit 12 inserted and mounted on the body unit from below. The light source unit 12 includes: a radiator 51 in which a light emitting module is disposed; and a locking spring 52 disposed at the radiator 51. The radiator 51 includes: a peripheral wall part 71; an insertion groove part 75 which is provided along the vertical direction on the peripheral wall part 71, and in which the locking part 39 is inserted; and a mounting groove part 76 which is communicated on one side in the circumferential direction on the lower part side of the insertion groove part 75, and in which the locking part 39 is movable in the circumferential direction. The mounting groove part 76 includes: an inlet groove part 77 in which the locking part 39 can pass; and a locking groove part 78 with which the locking part 39 can be engaged. The locking spring 52 protrudes from a lower side toward an upper side of a locking groove part 78 inside the peripheral wall part 71, comes into contact with the locking part 39 and energizes the locking part 39 upward.SELECTED DRAWING: Figure 1 【課題】放熱性を確保できるとともに、光源ユニットの着脱を操作性よく確実にできる照明装置を提供する。【解決手段】照明装置は、係止部39を有する本体ユニット、および本体ユニットに下方から挿入装着される光源ユニット12を備える。光源ユニット12は、発光モジュールを配設した放熱体51と、放熱体51に配設した係止ばね52とを備える。放熱体51は、周壁部71と、周壁部71に上下方向に沿って設けられ係止部39が挿通される挿通溝部75と、挿通溝部75の下部側の周方向一側に連通されて係止部39が周方向に移動可能とする取付溝部76とを有する。取付溝部76は、係止部39が通過可能とする入口溝部77、および係止部39が係合可能とする係止溝部78を有する。係止ばね52は、周壁部71の内側で係止溝部78の下方から上方へ向けて突出され、係止部39と接触して係止部39を上方へ付勢する。【選択図】図１
