ABSTRACT:
Ornamental and decorative light display utilizing LEDs constructed of two or more individual diodes. Each diode or portion of a diode is alternately selected and energized at a sufficient frequency that colors can blend to produce another color. The system provides for an extremely large configuration of LEDs to be driven at a low average power and at the same time to allow the user to select individual lights to be constantly illuminated or flash in response on oscillating voltage source or allow multicolored patterns to be generated using bicolor LEDs.
