    摘要： An intelligent lighting system may be installed using pre-existing electrical wiring, such as in a construction or retrofit environment. An intelligent lighting controller and an intelligent lighting fixture may be connected via electrical wiring that is configured for transmitting AC power signals. A commissioning signal may be transmitted to the intelligent lighting fixtures via the electrical wiring. In some cases, the intelligent lighting controller modifies portions of the AC power signal to indicate the commissioning signal. The intelligent lighting fixtures may receive the commissioning signal via the electrical wiring. In some cases, each intelligent lighting fixture that is connected to the electrical wiring, such as each intelligent lighting fixture on a lighting circuit in a room, receives the commissioning signal.

    摘要： An optic for aisle lighting includes a portion of an optical material defined by a length and a cross-sectional profile. The cross-sectional profile is characterized by a cavity within the optical material, two upwardly-facing surfaces of the optical material on opposite sides of the cavity from one another, and downwardly-facing surfaces of the optical material. The cavity is bounded by an upward facing aperture, and at least three faces of the optical material that meet at interior angles. Light received through the upward facing aperture is separated at the interior angles, and refracted by the faces of the optical material, into separate light beams equal in number to the faces. The two upwardly-facing surfaces internally reflect the separate light beams downwardly. The downwardly-facing surfaces intercept respective portions of the separate light beams, and refract the portions as they exit the optic.

    摘要： A housing and an endcap may provide a water-resistant enclosure for an emergency lighting component. An upper side of the housing may include a curved surface extending above a vertical side of the housing. The vertical side may include an inclined surface and an extended edge that provide a first concave opening below the curved surface. A base side of the housing may include a curved surface extending partially below the vertical side. The vertical side may include an additional extended edge and a curved surface that provide a second concave opening where the vertical side joins the base side. The endcap may include a rim that overlaps a portion of the housing. The first or second concave openings may receive fasteners to attach the endcap. Mounting brackets may attach to the first or second concave openings, such as to attach the housing to a surface.

    摘要： A method of assembling a light fixture includes assembling a light guide into a backing structure. The backing structure includes a sheet and first and second flanges at two opposite edges of the sheet. A row of light emitting diodes (LEDs) is installed on the first flange, positioned to direct light away from the first flange and toward the second flange, and generally parallel with the major surfaces of the flat sheet. The light guide is positioned between the flanges and against the backing structure. The width of the light guide is less than the distance between the LEDs and the second flange. The backing structure and the light guide are bent toward a bottom surface of the backing structure such that the flanges are drawn toward each other and such that the LEDs are drawn toward an input face of the light guide.

    摘要： A light fixture for lighting a surface includes a housing, a plurality of light sources, and a molded optic through which light from the light sources is directed. The molded optic further includes a plurality of concave aspheric optical surfaces in a first side of the molded optic, each of the concave aspheric optical surfaces partially enclosing one or more of the plurality of light sources, wherein the aspheric concave optical surfaces receive light directly from the respective light sources, and a plurality of convex aspheric optical surfaces disposed respectively opposite the plurality of concave aspheric optical surfaces on a second side of the molded optic, opposite the first side. The light sources and the aspheric optical surfaces cooperate to direct light onto the surface in an illumination field that is generally rectangular.
