The controller 10 includes: the system comprises a microprocessor module 200 for operation, a key detection module 201 for detecting key input of an input keyboard, a game judgment module 202 for processing games, an image processing module 203 for transcoding, a time module 204 for measuring the rotating speed of a fan, and an LED control module 205 for controlling LED lamp beads; all actions of the controller are finished in a short time, and image jamming cannot be caused.

the base 1 is a circular base, the protection cover 3 is an organic glass hemisphere protection cover, the protection cover 3 enables 8 flabellums of the fan to rotate in the interior without obstacles. The volumes of the second motor 7, the fan 8 and the support 6 within the range covered by the fan screen cannot be too large, so that light rays emitted by more LED lamp beads 9 are prevented from being shielded, and the visual effect is not influenced.

the vacuum area 4 is arranged between the body and the protective cover 3, so that the fan 8 cannot be influenced by air resistance when rotating, and the power consumption and the friction heat of the fan screen are reduced.

When human eyes observe a scene, light signals are transmitted into brain nerves, a short time is needed, after the action of light is finished, the visual image does not disappear immediately, the residual vision is called 'afterimage', and the phenomenon of vision is called 'persistence of vision'. An important property of the eye is ocular inertia, i.e. once a light image is formed on the retina, the vision will maintain the perception of this light image for a limited time, a physiological phenomenon called persistence of vision. For light stimulation of moderate brightness, the persistence time is about 0.1 to 0.4 seconds.
