An expandable light bar system includes a plurality of light bar segments each having an elongated hollow body and a lighting unit. Each lighting unit includes a housing with a plurality of light emitting diodes that are electrically connected to either a subsequent lighting unit or a power source. The housing is secured onto a ridge that is located along the top surface of the elongated body. An expansion adaptor is positioned between two light bar segments and allows the overall length of the joined light bar segments to be adjustable. A spacer is positioned at the center of the adaptor and defines a minimum separation distance between the segments. A pair of endcaps are removably secured to one end of each of the light bar segments and are configured to engage an existing fluorescent high output socket within a light box to support placement of the joined segments.

Disclosed is a lamp, including a base, a height adjustable controller, a steering gear, a light source, and a control assembly electrically connected to the light source. The steering gear includes a seat body, a positioning ring, a spring, a tray, a steering ball, and a steering tube connected to the steering ball and the light source, the seat body has a first through hole and a first opening communicated with the first through hole, the positioning ring and the tray are mounted in the first through hole, the spring is clamped between the positioning ring and the tray, the tray is clamped between the spring and the steering ball, a part of the steering ball is located in the first through hole, and a remaining part of the steering ball is protruded out the first through hole from the first opening and connected with the steering tube.

A connector for use in association with a lighting assembly that allows for components to be quickly assembled in an easily aligned configuration, including: a body having a first end, a second end, an interior sidewall, and an exterior sidewall; wherein the first end of the body and the second end of the body define a length therebetween; wherein a portion of the exterior sidewall of the body is threaded proximate the first end; wherein a portion of the exterior sidewall of the body is non-threaded proximate the second end; a first aperture associated with the first end of the body; a second aperture associated with the second end of the body; and a conduit positioned between the first aperture and the second aperture, wherein the conduit is adapted for containing an electrical cord from an associated lighting assembly.

A central shaft power connector for lighted ornaments is disclosed. A central support pole, such as for a Christmas tree is made in multiple parts joinable with an electrical and mechanical connector which joins the pole parts and simultaneously connects power or other circuits from one part to the other. The connector has two engaging sections and an outrigger platform which locates a connector off to the side of the poles but in alignment. Final alignment is obtained by a key and keyway in the connector parts. The connector is friction fit into a slot on each section so that the connector can be removed and replaced.

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.

A ground-plug LED lamp holder is provided, including a socket, a ground-plug portion, and at least one tube portion insertedly connected between the socket and the ground-plug portion, wherein the socket includes a core shaft configured to insertedly connect to a lamp, a mounting opening configured to mount a lamp cover to the socket, and a drainage hole configured to discharge liquid inside the socket via the tube portion. By means of the design according to the present disclosure, the lamp holder can be stably installed outdoors for use and has a quick adjustment of installation height, a reasonable distribution of wires and a drainage function, which meets a requirement for using outdoors.
