Reflecting device and lamp

The invention provides a reflecting device and a lamp, the reflecting device comprises a base, a rotating part, a connecting assembly and a plurality of reflecting blades rotationally connected with the base, and the rotating part sleeves 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, the two spherical hinge connecting structures are adopted, the rotating piece achieves adjustment of the opening and closing angles of the reflection blades through the connecting assembly, and along with changes of the opening and closing angles of the reflection blades, various symmetrical pattern effects with light and shade changes are obtained, and the effects of rendering the environment and manufacturing the atmosphere are achieved; and in addition, the structu
