Some embodiments of the present disclosure provide a tree lighting system. The tree lighting system includes a source of direct current electrical power, a power connector plug connected to the source of direct current electrical power, a strand of parallel-connected lamp elements, the strand connected to a lighting connector plug, and a body. The body includes a power connector jack configured to mate with the power connector plug to receive the electrical power, a lighting connector jack configured for providing the electrical power received at the power connector jack to the lighting connector and an electricity conductor connecting the power connector jack to the lighting connector jack.

An electrical connector for electrically coupling an electrical accessory to a furniture item may include a support column and a power interface set that may be provided in an interior of the support column. The power interface set may include an electrically contactable lower surface that may be spaced apart from an end of the support column. A distance between the electrically contactable lower surface of the power interface set and the end of the support column may be equal to a length of a retention portion of the support column. The retention portion and the electrically contactable lower surface of the power interface set may be together dimensioned for connection to an external power source coupled to the furniture item.

A light fixture apparatus having an LED circuit board mounting platform and an LED driver housing configured to attach to the circuit board mounting platform to form a module which is attachable anywhere along a wiring rail platform.

Disclosed is a waterproof LED light string that provides outdoor lighting in a simple and reliable manner. Waterproof bulb assemblies are used with replaceable LED light sources. The bulb assemblies are easily suspended from a rope or wire, screwed to a support, or magnetically supported from a ferrous metal support. Duplicate circuitry in the LED light source allows the LED light source to be connected in either direction.

An illumination device includes a supporting base, and a light-emitting element inserted in the supporting base. The light-emitting element includes a substrate having a supporting surface and a side surface, a light-emitting chip disposed on the supporting surface, and a first wavelength conversion layer covering the light-emitting chip and only a portion of the supporting surface without covering the side surface.

An electronic connector device is used to connect the light source board and the driver board of the LED light electrically. One end of the input terminal is fixed on the light source board and connect to the light source board electrically. The other end of the input terminal is the elastic clip structure. When the light source board is relatively combined with the driver board and the diver board is set near the light source board, the other end of the input terminal connects on the output terminal elastically. In the present invention, the electronic connector device fixes the input terminal on the light source board and relates the input terminal on the output terminal elastically by setting the output terminal on the driver board surface. Efficiently simplifying the structure of the whole electrical connector to make the electronic connector device owns the advantage of the structure.
