PURPOSE: To contact the opening edges of various thickness of mounted bodies by locking an elastic mounting strip, which has one side fixed to the side of a luminaire body and the other side bent to the body, to the body to be overhung to the outside. CONSTITUTION: For a mounting procedure, after a mounting 4 is inserted into the opening 10 of a ceiling along the side wall of a luminaire body 1, when a flange 2 is put in contact with the lower face 13 of the ceiling, the end 6 of the mounting 4 is operated and pushed out to be in contact with the opening edge 14 of the ceiling, to lock a protrusion 5 to an angular hole 3 at a preset position corresponding to a space to the thickness of the ceiling. In this way, the body 1 is mounted in such a stable condition that a ceiling makeup material 11 is held between the flange 2 and the mounting 4. Such a structure is not depending only on spring elasticity, so that there is not gap resulting from vibration and no certainty marred by the strength of a spring due to a material solid difference and almost constant holding force is maintained. |
