Patent ID: 6936980

Claim:
A wheel rim device with patterned light capable of automatically generating electric power, the wheel rim device comprising: a wheel rim with wheel spokes and a wheel axle disposed thereon, an accommodating room being concavely provided on an end face of said wheel axle; an automatic generating assembly arranged in said accommodating room of said wheel rim for generating an AC voltage when said wheel rim rotates; a rectifier/filter circuit connected with said automatic generating assembly to rectify and filter the AC voltage generated by said automatic generating assembly to obtain a DC voltage; a circuit board connected on one said wheel spoke of said wheel rim and having a plurality of light emitting components; and a programmable chip disposed on said circuit board and connected with said rectifier/filter circuit and said light emitting components, said programmable chip being used to drive said light emitting components to generate various glittering and jumping dynamic variations for accomplishing the effect of persistence of vision according to different timings of the output waveform of said programmable chip when said rectifier/filter circuit outputs a DC voltage, a color mixing effect being also accomplished between said light emitting components to display different color lights.
