An LED beacon rotating device, comprising a rotating LED lamp (1), a magnetofluid suspended lamp base (2), a drive device (3), a rotating power connector (4) and a controller (5); the rotating LED lamp (1) comprises an LED lamp (6), an LED lamp base (7) and a crystal triple prism (8); the magnetofluid suspended lamp base (2) comprises a container (9), magnetofluid (10) and an electromagnetic coil (11); the magnetofluid (10) is disposed inside the container (9); the electromagnetic coil (11) is installed on the container (9); the drive device (3) is fixedly connected to the rotating LED lamp (1); the rotating LED lamp (1) is suspended above the magnetofluid (10) of the magnetofluid suspended lamp base (2); the controller (5) is provided with a control wire connected to the electromagnetic coil (11); the controller (5) enables the electromagnetic coil (11) to generate a magnetic field used for magnetizing the magnetofluid so as to increase the specific gravity of the magnetofluid, as well as the buoyant force of the rotating LED lamp (1) in the magnetofluid (10), so the rotating LED lamp (1) is suspended and rotates in the magnetofluid (10), reducing the rotational friction force of the rotating LED lamp (1), and reducing the driving force for driving the beacon to rotate. |
