<p>The Frisbee has a disk body (1) having a circumferential protruding edge (2) extending from the disk in one direction. The disk also has at least one light emitting diode, at least one current source connected to the diode(s) and at least one light conductor connected to the diode(s). The light conductor is at least partially arranged around the peripheral edge (2) and, at least in those sections where it is applied, has such optical properties that, in additional to total reflection, light radiation also occurs.</p> |
