1. A light apparatus, comprising:
- a master controller for receiving a control signal requesting a color output and determining a timing sequence to achieve said requested color output;
a pulse controller coupled to said master controller; and
a driver coupled to said pulse controller and at least two different colored light emitting diodes (LEDs), wherein said at least two different colored LEDs are activated in an alternating fashion in accordance with a frequency of said timing sequence such that only one of said at least two different colored LEDs is powered on at a time such that a receptive sensor perceives the requested color output.

Abstract
A method and apparatus for achieving perceived light mixing via alternating colored light emitting diodes (LEDs) is disclosed. For example, a control signal to produce a requested color output is received. Then a timing sequence for at least two different colored LEDs to achieve the requested color output is determined. Then the at least two different colored LEDs are activated in an alternating fashion such that the requested color output is observed.

10. A method of achieving a perception of a desired color output using at least two different colored light emitting diodes (LEDs), comprising:
-
receiving a control signal to produce a requested color output; determining a timing sequence of said at least two different colored LEDs to achieve said requested color output; activating a first one of said at least two different colored LEDs to output a first color; deactivating said first one of said at least two different colored LEDs; activating a second one of said at least two different colored LEDs to output a second color after deactivating said first one of said at least two different colored LEDs in accordance with a frequency of said timing sequence such that said requested color output is observed. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A method of achieving a perception of a desired color output using at least two different colored light emitting diodes (LEDs), comprising:
-
receiving a control signal to produce a requested color output; determining a timing sequence of said at least two different colored LEDs to achieve said requested color output; and activating said at least two different colored LEDs in an alternating fashion in accordance with a frequency of said timing sequence to output two different colors in a same direction, such that each one of said at least two different colored LEDs are never activated simultaneously and said requested color output is observed. - View Dependent Claims (20)
