  • Patent number: 10683974
    Abstract: A multi-sectional artificial tree with internal and external power wiring for distributing and controlling power to a network of lights. The tree includes multiple tree sections, each tree section with a set of power wires inside a tree trunk, and a network of lighting wires outside the trunk. The network of lighting wires includes a tree-section wire network with a large gauge wire supplying power to groups of lights strings on branches on the tree trunk. Each group of branches has a branch-level lighting network with multiple connectors in series, and that connects to one connector of the tree-section wire network. Each branch-level lighting network powers multiple light strings connected in series, one light string per branch. The wires of the light strings are small gauge, and are connected by the branch-level connectors by a small-wire-to-large-wire connector.

  • Patent number: 10578260
    Abstract: A lighted decorative sculpture. The sculpture includes detachable sections that extend sequentially along an axis and may include detachable sections that extend laterally from the axis. A main power circuit including wires of a first gauge extends through the sculpture, and may include excess length between the detachable sections to enable separation of the detachable sections without stressing the wiring. Light strings electrically connected to the main power circuit distribute lighting to each of the detachable sections. The light strings include parallel wires that are of a second gauge, the second gauge being higher (lighter) than the first gauge. The lights may be light emitting diodes (LEDs). The lights may be oriented to emit a maximum intensity in a direction that is substantially parallel to the parallel wires to provide a distribution of light about the light string.
