Abstract

Certain embodiments of the disclosed technology include a decorative lighting system that can be integrated with an artificial tree. The decorative lighting system may include a white light emitting diode (LED) light string and a variable-color LED light string. The variable-color LED light string may employ LED lamps having embedded Red, Green, and Blue (RGB) LEDs. The RGB LED lamps may include an embedded integrated circuit (IC) configured to communicate with and control the energizing of each of the corresponding RGB LEDs to create a multitude of colors and color combinations that can vary with time to create a light show. An electronic controller in communication with the LED lamps may allow a user to select the mode for the light show and further may provide a periodic reset signal to restart or re-synchronize the light show.

Claims

1. A decorative lighting system comprising:

a wiring harness having two or more insulated conductors;

a plurality of variable-color LED lamps, each of the plurality of variable-color LED lamps comprising;

a plurality of color LEDs;

an embedded integrated circuit (IC) in communication with the plurality of color LEDs;

at least two electrical conductors in communication with the embedded IC for communication with an associated wiring harness;

a controller in communication with the wiring harness, the controller comprising a processor and at least one memory operatively coupled to the processor and configured for storing data instructions that, when executed by the controller, cause the processor to perform a method comprising;

selectively controlling at least one variable-color LED lamp according to an illumination sequence.
