Abstract

A device for creating moving light effects has a light source that is configured to pulse a light ON and OFF according to a desired pattern so as to create a moving light effect that is visible when the light source is moved. Some such devices can be programmed to custom-select color sets that are pulsed ON and OFF according to the desired pattern. Other such devices enable the user to custom select one or more patterns. Some devices can control a duty cycle of and LED of the light source by applying an eight bit octet over each duty cycle time in which the LED is pulsed ON or OFF based on a binary “1” or “0” of the octet. A microlight for use in artistic moving light shows such as gloving can employ such moving light effects, and some such microlights can be operated and programmed using a single actuator button.

Claims

1. A microlight for gloving, comprising:

a casing configured to enclose a control chip having an integrated circuit and adapted to control a multicolor LED bulb, the casing sized to fit within a glove and adjacent a fingernail of a user wearing the glove; and

the casing having a top surface, a bottom surface and a generally rigid shell portion;

wherein a flexible bottom member is provided at the bottom surface of the casing, the flexible bottom member being more flexible than the rigid shell portion and configured to conform to a shape of a user'"'"'s fingernail.

2. A microlight as in claim 1, wherein the casing has a bottom aperture, and the flexible bottom member extends across and seals the bottom aperture.

3. A microlight as in claim 2, wherein the casing has a top aperture, and a top flexible member extends across and seals the top aperture.

4. A microlight as in claim 3, wherein the top and bottom flexible members comprise an elastomer.

5. A microlight as in claim 4, wherein the top flexible member and the bottom flexible member are made of the same material.

6. A microlight as in claim 4, wherein the bottom flexible member is more flexible than the top flexible member.

7. A microlight as in claim 6, wherein the bottom flexible member has a coefficient of friction greater than a coefficient of friction of the top flexible member.

8. A microlight as in claim 1, wherein the microlight comprises a plurality of pre-programmed modes, and wherein the microlight comprises a routine for switching the microlight from a multi-mode operation, in which actuation of a button switches between the plurality of pre-programmed modes, to a one-mode operation, in which actuation of the button turns a single mode off and on.

9. A microlight as in claim 1, wherein the microlight is programmable to have up to a maximum number of color sets, and wherein each selected color can be selected to have one of at least two brightness levels.

10. A method of controlling a duty cycle of a light emitting diode (LED), comprising:

determining a desired duty cycle ON time per cycle for the LED;

dividing the ON and OFF time of the LED into at least one octet, the octet comprising 8 bits, each bit having a binary 1 corresponding to ON or a binary 0 corresponding to OFF, the total ON time of the octet corresponding to the desired ON duty cycle time; and

pulsing the LED ON during bits having a binary 1 and OFF during bits having a binary 0.

11. A method as in claim 10, additionally comprising providing an operational database in which the binary octet is saved, and retrieving the saved binary pattern.

12. A method as in claim 10, wherein if the desired duty cycle is less than 50%, no two adjacent bits have an ON setting.

13. A method as in claim 10 additionally comprising providing a second LED having a duty cycle, dividing the ON and OFF time of the second LED duty cycle into at least one octet, the octet comprising 8 bits, each bit having a binary 1 corresponding to ON or a binary 0 corresponding to OFF, the total ON time of the octet corresponding to the desired second LED ON duty cycle time, pulsing the second LED ON during bits having a binary 1 and OFF during bits having a binary 0, wherein at least one of the bits of the second LED having a binary 1 is timed to occur at the same time as at least one of the bits of the first LED having a binary 0.

14. A method as in claim 13 additionally comprising a table having a two digit hexadecimal code for each of the first and second LEDs, the first digit of the two-digit hexadecimal code corresponding to a hexadecimal number corresponding to a binary number representing the first binary nibble of the octet, the second digit of the two-digit hexadecimal code corresponding to a hexadecimal number corresponding to a binary number representing the second binary nibble of the octet.

15. A method of controlling a duty cycle of a light emitting diode (LED), comprising:

determining a desired duty cycle ON time per time cycle for the LED;

dividing the time cycle of the LED into a plurality of discrete successive time periods

assigning an ON or OFF instruction to each discrete time period so that the cumulative ON time per cycle equals the desired duty cycle ON time; and

performing the instruction of each discrete successive time period in order;

wherein performing the instruction comprises pulsing the LED ON only during time periods having the ON instruction.

16. A method as in claim 15, wherein the time cycle of the LED is divided into at least one octet having eight bits, and each bit corresponds to a discrete time period.

17. A method as in claim 16, wherein each ON bit stores a binary code of 1, and each OFF bit stores a binary code of 0.

18. A method as in claim 16, wherein the time cycle of the LED is divided into a plurality of octets.
