Abstract: A decorative lighting apparatus provides user-selectable color schemes corresponding to several holidays and other occasions for year-round use. In one illustrative example, the decorative lighting apparatus includes control circuitry which has a plurality of color-control outputs for coupling to color-control terminals of each one of a plurality of color-controllable lights along a decorative light strand. The control circuitry is operative to illuminate the color-controllable lights with any given color scheme by repeatedly time-multiplexing color-control signals at the color-control outputs to different interleaved sets of color-controllable lights along the decorative light strand. Each color-controllable light is a Red-Green-Blue (RGB) Light-Emitting Diode (LED). Preferably, the time-multiplexing rate is sufficient such that the RGB LEDs appear to be simultaneously illuminated along the strand (e.g. 32 Hertz or greater).

Abstract: A decorative lighting apparatus provides user-selectable color schemes corresponding to several holidays and other occasions and themes for year-round use. In one illustrative example, a decorative lighting apparatus includes a decorative light strand having a first wire with a first plurality of lamps coupled in series therealong, a second wire with a second plurality of lamps coupled in series therealong, a third wire with a third plurality of lamps coupled in series therealong, and a return wire coupled to ends of the first, the second, and the third wires. Each lamp of the first plurality has a first light-emitting diode (LED) device (e.g. red) which is coupled in parallel and in reverse orientation with a second LED device (e.g. orange/yellow), each lamp of the second plurality has a third LED device (e.g. blue) which is coupled in parallel and in reverse orientation with a fourth LED device (e.g. green), and each lamp of the third plurality has at least a fifth light-emitting diode (LED) device (e.g.

Abstract: An improved decorative lighting display using LEDs, CMOS integrated circuits and high current MOS transistors. This display provides for an extremely large configuration of LEDs to be driven at low average power and at the same time allows the user to select individual lights to be constantly illuminated or flashed in response to an oscillating voltage source. Moreover, this display allows multicolor patterns to be generated using bicolor LEDs.
