[0069] Among them, four color blocks are distributed in horizontal strips around the surface of the rotating lamp tube 403. During the rotation of the rotating lamp tube 403, when one of the color blocks on the rotating lamp tube 403 rotates to the rear side, the remaining three color blocks are blocked by the connecting plate 401 and the shielding plate 402 on the rear side, so that only one of the color blocks is displayed on the rotating lamp tube 403, thereby realizing the adjustment of the lighting properties.
