PURPOSE:To reduce the height for engaging or disengaging a latch to enable the thinness of luminaire by providing guide and mounting holes on the lower surface of the main body thereof, and protruding a guide member and the latch from the upper surface of frame. CONSTITUTION:Upon assembling, a luminaire main body is fixed to a mounting surface, and thereafter a frame 3 is suspended with two suspending chains 18. When the frame 3 is jointed to the lower surface of the main body 1 vertically from the lower direction, the chains 18 are stored in a storing part 30 around a guide member 26, and the guide member 26 slides along a guide edge 15 of a guide hole 14 by the aid of its tip with an acute angle to easily fit in a groove part 16, while an engaging part 36 of a latch 34 engages with an inner edge of a mounting hole 20 at the lower surface of a frame 11, so that mounting is made thin as a whole. In disassembling or dismounting, by pushing a release button 50 protruding from both sides of the frame 3, a latch 34 is disengaged from the mounting hole 20 so that the replacement of lamp and the like can be made without putting down the frame 3 onto a floor by the chains 18. |
