ABSTRACT:
An illumination device comprises a rotating member secured to a hub of a fan of a computer having a transparent case and including LEDs, a receptacle formed above a center, the receptacle including a projected head and an internal electromagnet, control circuits each for periodically controlling an on or off of one or more of the LEDs, a coil of wire surrounded by the electromagnet, and positive and negative terminals; and a fixed member secured to the fan and including a central slot snugly coupled to the head for fastening the receptacle and the fixed member together. Turning on the computer, the fan, the rotating member, and the coil of wire will rotate so as to cut magnetic lines across a space defined by the electromagnet, induce a voltage in the terminals, and illuminate or flash the LEDs.
