Abstract

A portable light-emitting display device having one or more rotating members including one or more light sources mounted or otherwise affixed thereto. The one or more rotating members are coupled to a motor. The motor and the light sources are each electrically coupled to one or more controllers, which control the speed at which the motor rotates the one or more rotating members and controls a lighting frequency and/or an intensity of all or one or more of the light sources or any combination thereof, to create a visual effect.

Claims

1. A portable light-emitting display device comprising:

a rotating member in the shape of a hoop, said hoop having a plurality of light-emitting diodes mounted or otherwise affixed thereto;

said rotating member coupled to a motor;

a power source comprising one or more conventional batteries;

said motor and said plurality of light-emitting diodes coupled to an integrated circuit,

said integrated circuit controlling the lighting frequency and/or intensity of said plurality of light-emitting diodes and the rotary speed of said rotating member, or any combination thereof, to create a visual effect.

2. The device of claim 1 wherein said plurality of light-emitting diodes are mounted or otherwise affixed to said rotating member equidistant along the periphery of said rotating member.

3. The device of claim 1 further comprising a switch electrically coupled between said power source and said motor.

4. The device of claim 1 further comprising a housing to enclose said rotating member, said motor, and said integrated circuit.

5. The device of claim 1 wherein said housing comprises a transparent spherical cover to enclose said rotating member.

6. The device of claim 1 wherein said housing comprises a handle assembly for housing said motor, said integrated circuit and said power source.

7. The device of claim 1 wherein said visual effect comprises the appearance of a three-dimensional sphere.

8. The device of claim 1 wherein said visual effect comprises the appearance of said light-emitting diodes moving in a direction opposite to the direction of rotation of said rotating member.

9. The device of claim 1 wherein said visual effect comprises the appearance of said light-emitting diodes slowing in movement.

10. The device of claim 1 wherein said visual effect comprises the appearance of said light-emitting diodes not moving.

11. The device of claim 1 wherein said rotating member comprises a plurality of concentric hoops, said concentric hoops each having a plurality of light-emitting diodes mounted or otherwise affixed thereto.

12. The device of claim 11 wherein said visual effect comprises the appearance of a plurality of three-dimensional spheres.

13. The device of claim 11 wherein said visual effect comprises the appearance of said light-emitting diodes moving in a direction opposite to the direction of rotation of said plurality of concentric hoops.
