CONTROLLER FOR A DECORATIVE LIGHTING SYSTEM
First Claim
1. An apparatus comprising:
- a controller configured to provide a data signal and a clock signal, the controller being electrically connectable to a bus comprising at least two conductors configured to carry the data signal and the clock signal from the controller to a driver electrically connected to the bus, wherein the controller is configured to provide the data signal and the clock signal to the driver for driving first, second and third light emitting diodes (LEDs) electrically connected to the driver, each of the first, second and third LEDs being configured to emit light at a different wavelength than either of the other LEDs, wherein the driver comprises a plurality of pulse width modulation registers selectable in combination to drive the first, second and third LEDs independent of one another to a blink rate and an intensity to control the color produced by the combination of the LEDs.

Abstract
A decorative lighting system includes a command controller, a plurality of illumination devices and a flexible cord interconnecting each. The command controller includes a microcontroller that provides a data signal and a clock signal. The data signal instructs a plurality of addresses corresponding to the lighting devices. Each illumination device has at least three light emitting diodes (LEDs). The LEDs each emit light at a different wavelength than either of the other LEDs. An integrated circuit LED is responsive to the data signal, clock signal, and power signal and drives the first, second, and third LEDs by to a blink rate and intensity. The LED driver includes a plurality of pulse width modulation registers that are selectable in combination to drive the LEDs to a blink rate and intensity independent of one another.
