Abstract: A low-voltage LED lighting system and 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: The inventive ceiling-mounted light-fixture support assembly includes a mounting bracket having upper and lower surfaces, a length, and a width between two width sides. The assembly also includes a fixture attachment member having a top with portions defining a top opening which has a width narrower than the width of the mounting bracket. The fixture attachment member further has a recessed portion defining a slideway which (a) is in lateral communication with the top opening, (b) has a width wider than the width of the mounting bracket, and (c) is spaced sufficiently lower than the opening-defining portions of the top to receive the two width sides of the mounting bracket. In use, the fixture attachment member can be positioned so that the mounting bracket is at least partially within the slideway and then repositioned so that the mounting bracket is within the top opening for light-fixture support.

Abstract: An LED floodlight fixture having two major principal axes in a fixture plane, the dimensions parallel to the fixtures third principal axis being substantially smaller than the largest dimensions parallel to the fixture plane. The fixture is characterized by a first outer surface which has a first central portion and a first edge-adjacent portion, an opposite second outer surface which has a second central portion substantially aligned with the first central portion and encompassing a light-emitting region and a second edge-adjacent portion having a boundary with the second central portion such boundary defining a reference plane, the first and second edge-adjacent portions meet at a perimetrical edge. The first and second central portions each extend across at least 25% of the area within the perimetrical edge.

Abstract: A bollard luminaire comprising a ground-mountable tubular vertical housing having a base portion and an upper portion, an annular lens member atop the housing in substantial axial alignment therewith, an upper reflector at the top of the lens member directing and reflecting light through the annular lens member, the housing and lens member being configured and the upper reflector positioned such that it receives upwardly directed light from below, and an LED module inside the base portion of the housing, the LED module being substantially centrally positioned, oriented for upward light emission, and having LED/optical-element sets themselves providing substantially vertically collimated light. In preferred embodiments, the housing is light-transmissive.

Abstract: A method for implementing lighting utilizes a lighting fixture having a plurality of lateral reflector positions, including selectively installing a first type reflector panel or a second type reflector panel in individual ones of the plurality of lateral reflector positions, the first type reflector panel having a greater uplighting capacity compared to the second type reflector panel, whereby the selectively installing determines, for the lighting fixture, a proportion of uplight versus downlight. For a plurality of tube positions disposed in a plane, a method may include vertically positioning a reflector assembly with respect to the plane. Individual reflector panels may be replaced by flexing the panel. A method may include providing a sensor switch operative to detect an occupant and connect an electrical path when the occupant is detected, and providing a selector for selecting ones of the ballasts to be connected to the electrical path by the sensor switch.

Abstract: An overhead industrial light fixture of the type including a housing, power-related components and a lamp-mounting socket. The housing has top and bottom walls and sidewalls together forming a substantially enclosed space, and the bottom wall defines a socket window. The power-related components and the socket are both secured to the housing and within the enclosed space, thereby to provide a low-profile fixture with its components within a single housing. Preferred embodiment include the socket having its lamp-receiving end substantially aligned with the socket window.

Abstract: A lighting apparatus mountable on a support and used for illuminating well-defined limited areas is provided. The apparatus includes a support frame pivotably mounted to the support thereby to allow the support frame to pivot about a predetermined axis, a light-generating system supported by the support frame, the light-generating system having a light source, a light-gathering/directing element, a guide rod and a reflector, the light-generating system generating one or more beams directed toward corresponding target areas, and preferably a shield for blocking non-reflected light.

Abstract: A light delivery system includes a light source. A first generally tubular, hollow coupling device with an interior light-reflective surface receives light from the source at an inlet and transmits it to an outlet. The coupling device increases in cross sectional area from inlet to outlet in such manner as to reduce the angle of light reflected from the surface as it passes through the device. A thermal-isolating region has an inlet positioned in proximity to an outlet of the coupling device and has an outlet for passing light to an optical member, the thermal-isolating region comprising one or more members. A waterproof container for the light source and coupling device has an aperture allowing light to pass out of the container. The aperture is sealed in part by a portion of a member of the thermal-isolating region. Advantageously, the system can be buried beneath the surface of the ground. This avoids the problem of people or equipment colliding with the system.

Abstract: A canopy light has a housing with a lower portion terminating in an opening, and also has a reflector in the housing. In the improvement, the lower housing portion includes a pair of spaced mounting members and the reflector includes a mounting lip affixed below the mounting members. The reflector body extends above the mounting members and is dimensioned to permit the reflector to be removed downwardly through the housing opening. A ballast assembly is above the reflector and is mounted on ballast supports inside the housing. The ballast assembly platform and the ballast supports are configured so that the ballast assembly can be lifted upwardly away from the supports (preferably without having to remove or loosen any fasteners) and then lowered downwardly through the housing opening. A new method for servicing a ballast assembly using access only through the housing opening (i.e., without having to gain access to the top of the housing) is also disclosed.
