The limiting column 15 passes through the top of the secondary circular ring 2, and a square groove 12 is provided at the connection between the top of the secondary circular ring 2 and the limiting column 15. The limiting column 15 is located in the square groove 12 and fits therewith, and a sliding groove 16 is provided on the outer wall of the limiting column 15. A limiting pin 3 is slidably connected in the sliding groove 16, and a spring 14 is fixedly connected between the end of the limiting pin 3 and the sliding groove 16. The limiting pin 3 passes through the outer wall of the secondary circular ring 2, and a through hole 13 is provided at the connection between the outer wall of the secondary circular ring 2 and the limiting pin 3. The limiting pin 3 passes through the through hole 13 and fits therewith, the limiting pin 3 is pressed to enter the sliding groove 16 and squeeze the spring 14, and then the limiting column 15 at the bottom end of the top cover 4 is aligned with the square groove 12 and inserted downward. Until the limit pin 3 coincides with the through hole 13, under the action of the spring 14, the limit pin 3 is inserted from the through hole 13, so as to realize the quick installation of the top cover 4, and the structure is simple and convenient to disassemble, which reduces the maintenance and replacement costs in the later stage. The LED light strip 11 is fixedly installed on the inner wall of the secondary ring 2, and the outer wall of the LED light strip 11 is bonded with a glass light guide plate 8, and the bottom end of the glass light guide plate 8 is bonded with a diffuser plate 7, and the diffuser plate 7 is bonded with the top of the main ring 1, and the top of the glass light guide plate 8 is bonded with a reflective paper 9, and the top of the reflective paper 9 is bonded with a rubber pad 10, which is fixedly connected to the bottom end of the top cover 4. Since most of the parts in this utility model adopt a detachable scheme, the rubber pad 10 plays a fixed and limiting role on the reflective paper 9, glass light guide plate 8 and diffuser plate 7 below. The LED light strip 11 is electrically connected with the wire 5, and the wire 5 passes through the top of the top cover 4, and a through groove 6 is provided at the connection between the top of the top cover 4 and the wire 5.
