A through hole 12e formed in the center of the flange cover 12 and having an inner diameter larger than the outer diameter of the ballast cover 6 is passed through the ballast cover 6 to cover the ceiling mounting plate 1, and the hole 1 of the flange cover 12 is inserted through the ballast cover 6.
2a to 12d are passed through threaded rods 4a to 4d and tightened with a nut 13 according to the embodiment. A hook 14 provided at the lower end of the ballast cover 6 suspends a hanging ring 16a provided at the upper end of the socket cover 16 containing the lamp socket 15, and the lamp socket 1
5 is equipped with a lamp 17, which is an HID lamp. Further, the upper side of the S-shaped ring 19 is suspended from a plurality of hooks 18 provided on the lower surface of the flange cover 12, and two concentric cylindrical heavy decorations 20 and 21 are suspended from the lower side thereof. Furthermore, decorative bodies 23 and 24 are suspended from these decorative bodies 20 and 21 via an S-shaped ring 22, and the glass body is attached to a threaded rod 25 extending from the outer decorative body 21 via a bush 26. A nut 29 is fitted with a light-transmitting body 27 as an example, and is further made into a cap nut through a washer 28.
It is fixed at Although only one transparent body 27 is shown in the figure, a plurality of transparent bodies 27 are provided over the entire outer peripheral surface of the decorative body 21.

According to this embodiment, since the ballast cover 6 with the ballast 7 built therein and the decorative bodies 20, 21, 23, 24 are individually attached to the ceiling mounting plate 1, the ballast cover 6, the decorative bodies 20, 21, Compared to an integrated type case in which one of 23 and 24 is attached to the other and attached to the ceiling mounting plate 1, the weight is divided, making the installation work safer and easier, and the ballast cover 6
