摘要:
An LED light fixture including a plurality of upwardly-protruding elongate fins extending therealong from distal fin-ends to proximal fin-ends adjacent to upward-flow openings through the fixture, the fins defining horizontal between-fin channels open at the distal fin-ends, and a plurality of flow-interrupters between adjacent fins changing air flow along the channels. The flow-interrupters may be less than half the heights of their respective between-fin channels and may be mounting bosses to serve the further purpose of facilitating assembly of the fixture.

A method, for implementing lighting by utilizing a lighting fixture having a plurality of laterally-spaced light source locations and corresponding lateral reflector positions, may include selectively installing a reflector of a first type or a second type in respective ones of the plurality of lateral reflector positions, the first type reflector having greater uplighting capacity compared to the second type reflector, whereby the selectively installing determines 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.

A light-generating and beam-establishing device including a cage having first and second cage members, having a wall defining a light opening surrounded by an annular washer-engaging surface, a pair of light-gathering/directing elements in end-to-end relationship at inlet ends and having outlet ends each of which is aligned with one of the washer-engaging surfaces, a lamp between the inlet ends, and a spring washer between and engaging the outlet end of each of the light-gathering/directing elements and the corresponding washer-engaging surfaces. The cage members are secured together with the light-gathering/directing elements and spring washers sandwiched therebetween.

摘要:
LED lighting apparatus including (1) a plurality of primary lenses each over a corresponding one of LED arrays spaced on a circuit board, and (2) a one-piece lensing member over the circuit board and having a plurality of secondary lenses each spaced over one of the primary lenses on the circuit board, the circuit board and lensing member having first and second mating features positioned and configured for inter-engagement for high-precision lens alignment. The circuit board and one-piece lensing member are each joined to a mounting surface of a heat-conductive member, and such assembly, while facilitating high-efficiency assembly, does not interfere with high-precision lens alignment.

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.
