Decorative light strand with voltage drop mitigation and method of use
11499703 · 2022-11-15 ·

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.

METHOD FOR TRANSMITTING CONTROL INSTRUCTIONS TO A PLURALITY OF RECEIVERS AND RECEIVER ADAPTED TO RECEIVE A LIGHT PIXEL CARRYING THE CONTROL INSTRUCTIONS
20230034202 · 2023-02-02 ·

Control instructions are transmitted to receivers by modulating light sources to generate light beams that are modulated with digital data streams for inducing control instructions in the light beams. Each light beam is applied to a pixel shaper element of a pixel shaper assembly to produce a light pixel, each light pixel carrying the control instructions of the light beam, each light pixel having a perimeter defined by the pixel shaper element. The pixel shaper assembly combines the light pixels into an image without significant overlap or voids between the light pixels emitted by the pixel shaper assembly. The light pixels are directed toward a projector lens for transmission toward the receivers. In a receiver, an optical receiver detects a light pixel. A controller decodes the control instructions received in the detected light pixel and uses the control instructions to control a function of the receiver.
