Abstract: An artificial tree that includes a tree trunk, branches on the tree trunk, a power circuit and a shaped light string. The shaped light string is on the branches, is in electrical connection with the power circuit and includes a pair of parallel wires and a plurality of light emitting diode (LED) assemblies electrically connected to the wires, the LED assemblies oriented to direct a maximum intensity of light in a first direction. The shaped light string defines multiple of lighting sections, that extend from a main portion of the shaped light string and include a first longitudinally-extending portion of the wires, a second longitudinally-extending portion of the wires, the second portion being adjacent to, and in contact with, the first portion, an LED assembly adjacent the first and second portions, and a bend forming an end portion of the lighting section.

Abstract: A rotation-locking lighted artificial tree that includes a first and second portion. The first portion includes a trunk, first electrical connector, and first wiring harness. The first electrical connector includes a first body portion and a first electrical contact set. The first body portion includes multiple projections electrically isolated from the first electrical contact set. The second tree portion includes a second electrical connector and a second wiring harness. The second electrical connector includes a second body portion and a second electrical contact set, the second body portion including multiple recesses. When the first tree portion couples to the second, the first and second electrical contact sets form an electrical connection and the recesses of the second body portion receive the projections of the first body portion, thereby electrically connecting and mechanically coupling the first tree portion to the second tree portion.

Abstract: A lighted artificial tree, including a first tree portion having a first electrical connector having a first electrical terminal positioned in line with a central vertical axis, and a second electrical terminal. The tree also includes a second tree portion that includes a second electrical connector having a first electrical terminal and a second electrical terminal, the second electrical terminal defining a ring shape that encircles the first electrical terminal. When the first tree portion is coupled to the second tree portion, the first electrical connector is coupled to the second electrical connector, such that the first electrical terminal of the first electrical connector is electrically connected to the first electrical terminal of the second electrical connector, and the second electrical terminal of the first electrical connector is electrically connected to the second electrical terminal of the second electrical connector.

Abstract: A locking artificial tree trunk including a first generally cylindrical, hollow trunk portion including an upper end, the upper end defining a notch, and a second generally cylindrical trunk portion including a body portion, a lower end having an insertable portion, and an upper end. The locking artificial tree trunk also includes a coupling mechanism having a body portion and an upper portion having a tab, and defining a channel for receiving the insertable portion of the lower end of the second trunk portion. The body portion is inserted substantially into the upper end of the first trunk portion with the tab of the upper portion aligned with the notch, thereby preventing rotation of the coupling mechanism within the upper end of the first trunk portion.

Abstract: A connector having enhanced protection against arcing during live or “hot” connection of a plug assembly to a receptacle assembly. The terminals of the connector, including the connection point of exposed wiring, are electrically isolated from each other with dielectric barriers built in to the connector, such as polymer partitions. Accordingly, protection against arcing is provided in a connector that is assembled fast and inexpensively, without need for a time consuming installation of wire and terminal coatings or sleeves (e.g., “shrink tube”), and with greater reliability. The connector can be used in a modular system for decorative lighting and having a controller module that is not hard wired to a light string. Use of the controller module independent of any of the light strings enables the controller to be used with any light string or with a replacement light string, in the event that the immediately connected light string fails.

Abstract: A reinforced wire for decorative lighting, the wire defining a central longitudinal wire axis and including: a longitudinally-extending reinforcing strand, the reinforcing strand comprising one or more fibers comprising a polymer material and defining a reinforcing-strand axis; a plurality of conductor strands wound about the reinforcing strand, each of the plurality of conductor strands defining a conductor strand axis; and an outer insulating layer adjacent to, and covering, one or more of the conductor strands. The reinforcing strand in cross section normal to the wire axis defines an asymmetrical shape.
