PURPOSE:To realize a thin form by providing an installing unit having a locking step, and a locking member and a release operation member to lock elastically allowable to lock and release to the locking step, and making the operating direction of the release operation member in the direction along the surface of a luminaire main body. CONSTITUTION:While a locking member 31 has a tapered guide on the upper surface, a release operation member 39 is projected integrally at the lower surface of the locking member 31, and the release operation member 39 is exposed from an opening 38. The tip of the locking member 31 is energized to project in the opening 38 by a spring 41, while a red remark display 50 is provided at the lower surface of the locking member 31 on the release operating direction side of the release operation member 39, so as to make the display 50 visible from the opening 38 when the release operation member 39 is pulled against the spring 41, and it is displayed that the locking member 31 is removed from a locking step 5. By hooking the plug blade 4 of the installing unit 1 to a hook sealing 3, and locking elastically the locking member 31 of a luminaire main body 2 to the step 5 of the installing unit 1, the main body 2 is installed. In this case, since the release operation member 39 is operated along the surface of the main body 2, an increase of the height of the main body 2 is prevented by the release operation member 39, and a thin form can be realized. |
