Ceiling lamp rotating structure

The invention provides a ceiling lamp rotating structure. The ceiling lamp rotating structure comprises a magnetic rotating piece and a direction controlling piece. The magnetic rotating piece comprises a driving rotating module, a driven rotating module and an insulating piece, wherein the driving rotating module is isolated from the driven rotating module in an insulated mode through the insulating piece. The driven rotating module is connected with the direction controlling piece. The direction controlling piece is connected with a light source assembly. The insulating piece comprises a first sealed cylinder structure. The driven rotating module, the direction controlling piece and the light source assembly are arranged in the first sealed cylinder structure. By the adoption of the scheme, control over the illumination direction of the light source assembly can be achieved, and a waterproof function of the LED down lamp can also be achieved. In addition, due to the facts that a transparent resin material i
