A recreational or competitive flying disc includes an illumination system
employing an array of flexible optical fibers to distribute the light of
a single light emitting diode (LED) from the rotational center of the
disc to its outside periphery. A small water-resistant compartment
centered on the underside of the disc houses the LED, battery, and the
illumination control. The leads of the LED also serve as the contacts of
the battery. One end of each of the optical fibers is embedded in the
LED, and the other end extends radially from the central housing on the
underside surface of the disc to the rim of the disc. The flying disc is
illuminated without altering the aerodynamic properties of the disc.
