Abstract

A hair ornament includes multiple light-emitting diodes (LEDs) which are manufactured as a single component so that their combined output can be focused on the end of a bundle of optic fibers. The fibers may be woven in the hair or wig of a wearer of the ornament. For a preferred embodiment of the invention, three LEDs, each of which emits a primary color (generally red, green or blue), are provided. Each LED is coupled to a flasher circuit having both variable frequency and variable duty cycle. At low frequencies (i.e., less than about 18-20 flashes per second), the flashes are seen as discrete colors. However, as the frequencies are increased, only a single color is visible. The color of that single color can be varied over the visible spectrum by varying the duty cycles of the three LEDs. One use of the preferred embodiment is to adjust the projected color to coordinate with clothing of the user.

Claims

1. A decorative hair ornament comprising:

a housing;

a battery installed within said housing for discharging electric current on demand;

at least two light-emitting diodes (LEDs) secured to said housing, each of which produces a different color output when energized with electric current from said battery;

a diffuser lens which combines the light output from said LEDs;

a plurality of optic fibers bundled together at one end, the bundled end of said optic fibers being secured to said housing, and positioned so that the combined light output is incident thereon, thereby transmitting light from each of the LEDs into the bundled ends of substantially all of the optic fibers;

control circuitry installed within said housing and powerable by current from said battery that provides flashing capability and duty cycle variability of to each of the LEDs.

2. The decorative hair ornament of claim 1, wherein the duty cycles of each of the LEDs is varied automatically to continually vary the perceived color of the common beam.

3. The decorative hair ornament of claim 1, wherein all the LEDs are fabricated as a single component having a common negative electrode.

4. The decorative hair ornament of claim 3, wherein said single component also integrates said diffuser lens.

5. The decorative hair ornament of claim 1, wherein three LEDs are provided, each of which produces light of a primary color.

6. The decorative hair ornament of claim 5, wherein the primary colors produced are red, green and blue.

7. The decorative hair ornament of claim 1, wherein said control circuitry is adjustable by the user to vary the flash rate of the LEDs.

8. The decorative hair ornament of claim 1, wherein said control circuitry is adjustable by the user to set the duty cycle of each LED to a desired level.

9. A decorative hair ornament comprising:

a housing;

a battery installed within said housing for discharging electric current on demand;

at least two, and no more than three, light-emitting diodes (LEDs) fabricated as a single component which incorporates a single diffuser lens which combines the light output from said LEDs, each LED producing a different color output when energized with electric current from said battery, said single component being secured to said housing;

a plurality of optic fibers bundled together at one end, the bundled end of said optic fibers being secured to said housing, and positioned so that the combined light output is incident thereon, thereby transmitting light from each of the LEDs into the bundled ends of substantially all of the optic fibers;

control circuitry installed within said housing and powerable by current from said battery that provides flashing capability and duty cycle variability of to each of the LEDs.

10. The decorative hair ornament of claim 9, wherein each of the LEDs have a ground electrode in common with the other LEDs.

11. The decorative hair ornament of claim 9, wherein the duty cycles of each of the LEDs is varied automatically to continually vary the perceived color of the common beam.

12. The decorative hair ornament of claim 9, wherein each of the LEDs produces light of a primary color.

13. The decorative hair ornament of claim 12, wherein the single component contains three LEDs, and the primary colors produced are red, green and blue.

14. The decorative hair ornament of claim 9, wherein said control circuitry is adjustable by the user to set the flash rate of the LEDs.

15. The decorative hair ornament of claim 9, wherein said control circuitry is adjustable by the user to set the duty cycle of each LED independently of the others.

16. A decorative hair ornament comprising:

a housing;

a battery installed within said housing for discharging electric current on demand;

three light-emitting diodes (LEDs) fabricated as a single component which incorporates a single diffuser lens which combines the light output from said LEDs into a generally cylindrical common beam, said three LEDs sharing a common negative electrode, each LED producing a different primary color light output when energized with electric current from said battery, said single component being secured to said housing;

a plurality of optic fibers bundled together at one end, the bundled end of said optic fibers being secured to said housing, and positioned so that the combined light output is incident thereon, thereby transmitting light from each of the LEDs into the bundled ends of substantially all of the optic fibers;

control circuitry installed within said housing and powerable by current from said battery that provides flashing capability and duty cycle variability of to each of the LEDs.

17. The decorative hair ornament of claim 16, wherein the duty cycles of each of the LEDs is varied automatically to continually vary the perceived color of the common beam.

18. The decorative hair ornament of claim 16, which further comprises a claw-type hair clip attached to said body.

19. The decorative hair ornament of claim 16, wherein the outer surface of each of the optic fibers is coated to prevent the bleed-out of transmitted light.

20. The decorative hair ornament of claim 16, wherein said control circuitry is adjustable by the user to set the duty cycle of each LED.
