Abstract: A track light module for use with a low-voltage track carrying a pair of elongated conductors transversely spaced from each other and accessible through a longitudinal slot in the track. The module includes a first housing that contains a printed circuit board carrying an LED and forming an aperture permitting light from the LED to be radiated beyond the first housing. A second housing carries a pair of electrical conductors adapted to extend into the low-voltage track to make contact with the conductors within the track. The second housing also includes surfaces for fastening the second housing to the track when the second housing and the track are moved relative to each other. A pair of electrical contacts on the printed circuit board contact the conductors carried by the second housing and thereby receive electrical power for the LED. A connector attaches the first and second housings together.

Abstract: An adapter for an electrical line voltage track system includes a housing having a first end adapted for mounting to an electrical source or an electrical fixture, and a second end adapted for mounting to a line voltage track. The housing includes a housing cover coupled to a housing body. The housing cover is movable relative to the housing body between a closed position and an open position. A supporting sleeve is movably coupled to the housing, and a plurality of electrical contacts, including a fixed contact and a movable contact, are also coupled to the housing. The movable contact is movable, relative to the housing, between an engaged position and a disengaged position. In the engaged position, the movable contact causes electrical contact with the line voltage track. In the disengaged position, electrical contact is removed.

Abstract: A track light assembly includes a low-voltage track. A light module comprises an elongated thermally conductive housing fitted over the track. The housing may also surround the track. The housing preferably forms an elongated channel. An elongated printed circuit board (PCB) is mounted on the thermally conductive housing and carries a plurality of clusters of light emitting diodes (LED's) distributed over the PCB surface. An elongated lens is fitted over the PCB and LED clusters. A track adapter attached to an end portion of the track includes electrically conductive contacts for electrically coupling the conductors in the track housing with contacts on the printed circuit board. Thus, a cool running, elongated, linear light module is provided which is adjustably placeable along the length of the track.

Abstract: A flexible cable is provided for a lighting system having a power supply that includes a power supply input to receive a first signal having a first frequency and a circuit for converting the first signal to a second signal, and at least one luminaire coupled to a lamp driver. The cable comprises a first leg of wires for carrying the second signal. The first wire electrically connects a loop output of the power supply to an input of the lamp driver and a second wire electrically connects an output of the lamp driver to a loop return of the power supply. The cable further comprises a second leg of wires electrically connected to a ground of the power supply and the ground of the lamp driver. The second signal has a substantially constant current and a second frequency distinctly higher than the first frequency. The flexible cable further comprises a modular connector.

Abstract: An apparatus is provided for securing a trim frame to a housing member in a recessed lighting fixture. The apparatus includes a spring associated with the trim frame having a top edge, a left edge, a right edge, and a bottom edge, a left portion, a right portion, and a center portion between the left portion and the right portion. The left portion is connected to the center portion along a first bend, and the right portion is connected to the center portion along a second bend. The left portion includes a first lead-in portion formed by a third bend and a first retention portion formed by a fourth bend, and the right portion includes a second lead-in portion formed by a fifth bend and a second retention portion formed by a sixth bend.

Abstract: A connector is provided for electrically connecting a coaxial cable having a conductive inner wire surrounded by a conductive outer jacket and an insulator therebetween to a two-wire circuit. The connector comprises a conductive bottom contact member having a first passageway dimensioned to fit only the inner wire and the insulator therethrough and to block the conductive outer jacket. A conductive top contact member has a second passageway for the inner wire and the insulator and a clamping member for securing the inner wire to the top contact member. An insulating member for electrically separates the bottom contact member from the top contact member. A pendant-style light fixture using the coaxial connector is also disclosed.

Abstract: A lighting assembly that includes a light fixture adapted to be disposed in relation to an opening defined in a surface of a structure such that a lamp may be installed in the light fixture through the opening, a trim having an outer surfaces, and an intumescent layer on the outer surface of the trim. The trim is adapted to engage the light fixture so that the outer surface of the trim on which the intumescent layer is disposed is positioned in proximity to the opening in the structure. The intumescent layer is adapted to expand to form a fire resistant seal between the trim and the structure when the intumescent layer reaches a predetermined temperature.
