Abstract
A decorative light strand having a power distribution modality in which a high voltage wire feeds a power wire which provides a supply voltage to light engines in an effective operational voltage range. The high voltage wire interfaces with the power wire through longitudinally distributed DC voltage regulators that step down a higher voltage to the operational voltage of a number of light engines. An equilibrium voltage is thus achieved such that all light engines are similarly powered. The decorative light elements may be light-emitting diode (LED) light engines with a chip-controlled red-green-blue (RGB) interface, which controls user perceived effects, such as on/off frequency, color, intensity, and color temperature of each light engine at any given time, thus achieving a wide variety of decorative effects. The decorative light strand includes a distribution wire and DC voltage regulator which enables long-strand lights of indiscriminate lengths for custom installations.
