Abstract: A light engine is provided including a thermally conductive housing including a generally cylindrical wall defining a cavity, the cylindrical wall includes an inner surface and an outer surface, a plurality of ducted passageways being axially disposed on the outer surface, a light module including at least one light emitting diode (LED) for producing visible light, the light module coupled to a first end of the housing, wherein heat generated by the at least one LED is conducted to the housing, and a current driver circuit arranged on a substrate, the substrate configured to be disposed in the cavity of the housing and electrically coupled to the light module for providing current to the at least one LED. The ducted passageways aid in convective heat dissipation through a “chimney” type of affect.

Abstract: A fluorescent adapter having a housing including a tip contact compatible with an electrical socket, a threaded ring contact compatible with the electrical socket, the ring contact surrounding the housing and rotatable with the housing when the housing is rotated in a first direction and not rotatable with the housing when the housing is rotated in an opposite direction, and a fluorescent ballast supported by the housing and having input electrodes in electrical contact with the tip contact and the ring contact, respectively, and output electrodes for removably receiving the contact pins of a fluorescent lamp. The adapter is easily inserted into the socket but is not removable after insertion.

Abstract: A rail lighting system includes an adapter having contact members with elongated portions. A body having an opening for a rail receives the contacts such that the elongated portions extend adjacent the rail. A wedge includes members that engage the contacts to urge the elongated portions toward the rail. The wedge is secured to a cap that threadedly engages the body. The rail includes at least one conductor in opposite end portions of the rail with respect to its depth. The conductors of the rail may include a single conductor or, alternatively conductors on opposite sides of the rail. A lighting fixture spring clip includes sets of opposite tangs including a first set having V-shaped end portions to engage a notched lamp base and a second set having curved end portions for engaging an enclosure barrier.

Abstract: The invention relates to a device for electrically connecting wires. The device includes first and second nonconductive housing sections adapted to be mateably secured together to form a substantially closed housing. An electrically conductive contact is disposed within the housing and has a first end including a tang for piercing the insulation of the first wire and making electrical contact with the center conductor thereof, a second end including a tang for piercing the insulation of the second wire and making electrical contact with the center conductor thereof, and a connecting portion electrically connecting the first end and the second end to provide an electrical path from the center conductor of the first wire through the contact to the center conductor of the second wire.

Abstract: An extension wire socket includes a nonconductive U-shaped portion, a nonconductive chamber and at least one electrical connector supported therein. The U-shaped portion is defined by a base and opposed tabs extending from the base. The U-shaped portion snaps over insulated electrical conductors. The nonconductive chamber is adjacent to the base. The socket accepts the terminal end of an extension wire. Each connector includes a spiked prong for piercing the insulation of one of the conductors when the socket is attached to the conductors. Each connector also includes an insulation displacement terminal for attaching the terminal end of the extension wire thereto. The spiked prong is located in the U-shaped portion and the insulation displacement terminal is located in the chamber. The connector is slotted into the socket in a manner that protects most portions of it from exposure and unwanted flexing and stresses.

Abstract: Lighting trim attaches to lamp housing by mating one or more trim attachment regions with respective housing attachment regions. Each trim attachment region includes a finger thereon. The finger ends in a downwardly curved lip. Each housing attachment region includes a slot and a detent sector adjacent to and in communication with the slot. The trim's finger and the housing's slot are dimensioned so that the finger can pass through the housing slot when they are aligned with each other. The finger's lip becomes seated into the housing detent sector upon subsequent rotation of the trim with respect to the housing.

Abstract: An electrical connection assembly for a baseless cartridge bulb includes two electrical connectors attached to a housing. The housing includes tabs which snap onto a channel partially surrounding a pair of insulated electrical cables. One end of each of the connectors includes a spring tab for accepting a loop contact pin of a cartridge bulb. The other end includes a spiked prong for piercing the cable insulation and becoming embedded therein.

Abstract: A selectably-configurable lighting fixture comprising a body having a coupling thereon for selectably and releasably receiving at least one of a plurality of interchangeable components. The components include at least a shade and a mounting member for mounting the fixture to a support. The fixture also comprises a lamp support for supporting a lamp on the body in operative relation to the shade for illuminating a space adjacent the fixture.

Abstract: A low voltage track lighting system includes a flexible power track and one or more light fixtures removably attachable to the track for energization. The track has an elongated support member of an electrical insulating material, the support member being generally I-shaped, defining lateral electrical conductor-receiving channels, the conductors being flat strips extending on-end along the sides of the support member and exposed therealong, the conductor orientation enabling the power track to be bent in a horizontal plane, but not in a vertical plane.
