Reflecting device and lamp

The utility model provides a reflecting device and a lamp, the reflecting device comprises a base, a rotating piece, a connecting assembly and a plurality of reflecting blades rotationally connected with the base, and the rotating piece is sleeved on the base and is configured to rotate relative to the base; the connecting assembly is in spherical hinge connection with the rotating piece and the reflecting blade, and the rotating piece adjusts the opening and closing angle of the reflecting blade through the connecting assembly. Compared with the prior art, by adopting the two spherical hinge connecting structures, the rotating piece can adjust the opening and closing angles of the reflecting blades through the connecting assembly, and along with the change of the opening and closing angles of the reflecting blades, various symmetrical pattern effects with light and shade changes are obtained, and the effects of rendering the environment and creating the atmosphere are achieved; and in addition, the structure
