Patent ID: 7015825

Claim:
A decorative lighting system, comprising: a command controller comprising: a microcontroller for providing a data signal and a clock signal, the data signal including instructions related to a plurality of addresses; and a power supply for providing a power signal; a flexible cord having a first end and a second end, comprising at least two conductors capable of carrying the data signal, clock signal, and power signal, the first end being electrically connected to the command controller; a plurality of illumination devices, each illumination device being disposed between the first end and second end of the flexible cord, each illumination device comprising: a substrate including a first light emitting diode (LED), a second LED, and a third LED, each of the first, second, and third LEDs emitting light at a different wavelength than either of the other LEDs; and an integrated circuit LED driver being electrically interconnected via the at least two conductors to the command controller and responsive to the data signal, clock signal, and power signal for driving the first, second, and third LEDs, the integrated circuit LED driver comprising: a plurality of pulse width modulation registers selectable in combination to drive the first LED, second LED, and third LED independent of one another to a blink rate and an intensity to control the color produced by the combination of the LEDs; and an electronically programmed address circuit for storing an address therein, the integrated circuit LED driver being responsive to the data signal upon receiving a corresponding address from the command controller.
