PURPOSE:To prevent breakage of an accessory by stopping it temporarily in the middle when the accessory is installed on a luminaire by a V spring, and restraining an impact when a frame butts the ceiling surface without installing it in one breath. CONSTITUTION:When an accessory 6 is installed on a luminaire body 4, a stepped V spring is hooked on a spring receiving metal fitting 3. Next, the accessory 6 is pushed up toward the ceiling surface 7. At this time, the step parts of the stepped V spring 1 are hooked on the spring receiving metal fitting 3, and are stopped temporarily. |
