  • Patent number: 5611720
    Abstract: A flying disc toy of the FRISBEE.RTM. type provides a lighting system having LEDs used in conjunction with a glow-in-the-dark body. The flying disc provides a raised center section having a plurality of LEDs mounted radially at spaced intervals. A motion responsive switch is used to turn on the LEDs in response to movement of the disc. Electronic circuitry controlling the LEDs provides a timer circuit that automatically turns off the LEDs a timed period after they are turned on. As a result of the motion sensitive switch and timer circuit, the lights flash on and off rapidly as the disc flies through air turbulence. No on-off switch is required, since the circuitry rapidly turns itself off. Because no on-off switch is present, all components are carried in a waterproof raised center section having no opening. An optional battery plug structure is threadedly insertable into a plug receiver in the raised center section, and allows the user to replace the battery.
