  • Patent number: 11353176
    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: 10982828
    Abstract: A multi-sectional artificial tree with a tree lighting system. The tree includes a DC power converter, and lower and upper tree sections. Each tree section includes a tree frame with groups of branches and light sets in a ratio of one light set per branch. The thin, single-conductor wires of each light set are affixed only to a single branch to prevent bending and breaking. Each group of branches and light sets is positioned at a particular height on the trunk of the tree. An upper tree section includes fewer branches per group, as compared to a lower section, and thus includes fewer light sets per group. The light sets are wired in series from branch-to-branch, though the number of light sets per group varies from section to section. Consequently, a resistive load is used in the upper tree section to adjust a voltage applied to individual light sets.
