PROBLEM TO BE SOLVED: To provide a recessed luminaire, capable of being executed corresponding to thinness and thickness of a ceiling material, constituting a ceiling surface and holding a locking state of a mounting spring with respect to strong vibration generated, when the apparatus is transported. SOLUTION: This luminaire is constituted of an apparatus main body 1, which is inserted into an embedding hole of a ceiling surface 11 and is mounted by abutting an outer collar part 21, provided on a lower part on a mounting lower surface around the embedding hole, a mounting spring 2 which is fixed to a mounting part 23 provided on a side surface of the apparatus main body 1 at a lower end part, is provided so that the upper end part is projected elastically outward and relatively pushes up the apparatus main body 1 by a force spreading outward and a mounting spring locking spring which maintains the mounting spring 2 at a position adjacent to the apparatus main body 1, locking the mounting spring 2 at a portion close to the mounting spring 2, projects outward from the mounting spring 2 in the locking state and releases the mounting spring 2 from the locking state by abutting on a peripheral surface of the embedding hole, when the apparatus main body 1 is inserted into the embedding hole. |
