PURPOSE:To facilitate assembling and provide wide usability by rotatably shaft- supporting a lighting body part by an inner main body part, and holding the inner main body part itself by an outer main body part through mounting springs in such a manner as to be attachable and removable, and rotatable. CONSTITUTION:A down light is installed on a ceiling 30 by fitting an outer main body part 11 to an opening formed on the ceiling 30 from the lower surface side and sandwiching the ceiling 30 between a collar part 17 and a bracket 19. In this case, an inner main body part 12 held by mounting springs 15 is rotatable in the horizontal direction a-b, and a lighting body part 13 held by the inner main body part 12 through a shaft part 28 is rotatable in the direction c-d. As the inner main body part 12 is held by the outer main body part 11 through the mounting springs 15, the inner main body part 12 can be pulled downward and removed even in the state where the outer main body part 11 is mounted on the ceiling 30, and conversely, the inner main body part 12 can be installed by inserting the inner main body part 12 to the outer main body part 11 from under. |
