Abstract

A light emitting diode fan pen is provided that includes a rotatable fan leaf that is coupled to an electric motor. A circuit board is also rotatably coupled to the fan leaf and electric motor. At least one light emitting diode in electrical communication with the circuit board is visible on the fan leaf. A battery producing a voltage sufficient to energize the motor, and a switch for selectively forming an electrical circuit is provided. A housing at least partially encompassing the motor and the switch has an apical end at which the motor is located. An ink reservoir is within the housing. A voltage step-up circuit is provided on the circuit board to receive a voltage output from the battery step-up voltage produced by the step-up subcircuit to power the at least one light emitting diode. A multimode switch is provided to provide a user with various fan operational modes.

Claims
