Abstract: A low-voltage LED lighting system, LED lighting fixtures, and a method for installation thereof in which the system includes: (a) at least one LED lighting fixture each having one or more LEDs; (b) at least one remotely-located power driver; and (c) interconnections between the at least one LED fixture and the at least one driver using communication network cabling and standard 8P8C network connectors. Preferred lighting fixtures are recessed lighting fixtures adapted for ceiling mounting.

Abstract: An LED apparatus including (a) a mounting board, (b) a plurality of LED packages thereon, (c) a lens member over each LED package, and (d) a safety barrier positioned over the mounting board, the barrier having sufficient thickness for enclosure of electrical elements on the mounting board and including a plurality of openings each sized to permit light from an LED package to pass therethrough and through a light-transmission portion of the lens member over such LED package to prevent finger-contact of electrical elements on the mounting board when the light-transmission portion is not present.

Abstract: A retrofit canopy luminaire assembly adapted for downward illumination and having a housing with inwardly-directed ledges near the lower edges of the housing. The luminaire has at least two support brackets secured to at least one of the ledges; a face plate removably secured to the brackets on the lower side of the housing; and a hanging tether attached to one of the brackets and to the face plate. The face plate is adapted to hold lighting fixture components. When the face plate is removed from the brackets, the face plate hangs freely held by the tether to allow free access to the inside of the luminaire.

Abstract: A ballast for electrical lighting fixtures with improved thermal protection features has ballast laminations, primary and secondary coils, and a thermal protector, the thermal protector being wired in series with the secondary coil. The ballast preferably is of the type having multiple input voltage taps on the primary coil; in such cases, the electrical positioning of the thermal protector in series with the secondary coil causes the wiring assembly of the thermal protector (as part of the ballast) to be independent of the primary coil input voltage tap used in a particular application. Improved electrical lighting circuits for high-intensity-discharge lamps have the above-described thermally-protected ballasts.

When the ballast is of the type having multiple input voltage taps on the primary coil, the electrical positioning of the thermal protector in series with the secondary coil causes the wiring assembly of the thermal protector (as part of the ballast) to be independent of the primary coil input voltage tap used in a particular application. Improved electrical lighting circuits for high-intensity-discharge lamps may be obtained, the circuits having the above-described thermally-protected ballasts.

Abstract: A unitary bracket which is particularly suited for mounting a thermal protector to a ballast for an electrical lighting fixture is disclosed. The unitary bracket has a holding-face portion with opposite edges and a mounting end, edge portions on the opposite edges angled toward the electrical device, and a mounting-end portion on the mounting end and extending toward the electrical device, the mounting-end portion having a mounting tab for engagement with the electrical device, the portions being configured and dimensioned to sandwich the thermal protector against the electrical device when the mounting-end portion is secured thereto. Also disclosed is an improved thermally-protected ballast including such bracket.
