[0024] The lamp body 195 is fixed to the upper surface of the base 110, and the fins 170 are stacked on the base 110. The lamp body 195 also includes a threaded rod 193 and a nut 194. The lower end of the threaded rod 193 is fixed to the upper surface of the base 110, and the threaded rod 193 passes through the fins 170. The nut 194 is threadedly sleeved on the threaded rod 193. The arrangement of the threaded rod 193 and the nut 194 enables the plurality of fins 170 to be fixed to the base 110. The lamp body 195 is arranged in the fins 170. The fan 1 80 is fixed on the outer wall of the fin 170, and a mounting hole 150 is opened on the base 110. There are multiple mounting holes 150. The setting of the mounting holes 150 facilitates the installation of the base 110. The lampshade 160 is fixed on the upper surface of the base 110 and also includes a bolt 192.
