Abstract:
A light fixture for mounting in a t-bar ceiling structure, the light fixture includes a housing configured to support a ring-shaped lens to at least partially surround an inner reflective surface, the inner reflective surface being configured to at least partially reflect light incident thereon from the lens, to present a mirage effect in a transition zone near the lens.
Abstract:
Described are various embodiments of a method and apparatus for outlining recessed installation of a component within a surface material. In one embodiment, the apparatus generally comprises two or more template or alignment modules adjacently disposable against the surface material and each comprising opposed edges that can be aligned with adjacently disposed edges so to define a substantially continuous spacing along these adjacently disposed edges. This spacing is generally dimensioned so to accommodate a corresponding component dimension such that, the aligned edges guide removal of surface material along the spacing to accommodate recessed installation of the component within the surface material.

Abstract:
A linear light fixture assembly for supporting a light fixture in a ceiling structure, comprises a light fixture mounting structure having a pair of opposed boundary regions configured to fit within a designated light fixture receiving region in the ceiling structure, and a plurality of spring elements configured to spaced outwardly from at least one of the boundary regions, each spring element having a mounting region configured to be anchored to the mounting structure and a free end region to extend therefrom and to be laterally outwardly biased in a first position to form a path of contact with a support surface region on the ceiling structure to anchor the structure in the receiving region, each of the spring elements configured to be movable toward the corresponding boundary region in a second position to release the path of contact to release the light fixture from the receiving region.
Abstract:
An LED luminaire having a housing positionable at a structure location for providing illumination. At least one first LED light engine is located within the housing. The housing has at least one light output boundary and is configured to direct light therein toward the light output boundary. A light guide is configured to be located at the light output boundary to receive light contained within the housing to emit non-directional light at the light output boundary. The at least one first LED light engine includes at least one first LED light source providing directional light at the light output boundary. The first LED light engine includes a shroud adjacent the light guide providing directional light from the LED light source to a target location beyond the luminaire. The shroud structure provides an optical path from the LED light source through the light guide for providing non-directional light.
Abstract:
A single edge lit lighting module is disclosed which produces tailored light distributions valuable in many illumination applications. The lighting module comprises a unique light scattering optical element with volumetric light scattering properties which works in combination with configured reflective surfaces and optional surface relief features, Light distributions attainable using the invention are non-lambertian and anisotropic. Light distributions with one or more lobes of peak intensity can be produced which include, but are not limited to, symmetric and asymmetric batwing distributions, asymmetric distributions for perimeter lighting and symmetric distributions. The invention's unique single edge lit construction provide the means for achieving this without need for conventional two lit edges and within a compact form factor with narrow width, particularly well-suited for linear lighting fixtures that are suspended, surface mounted or recessed. Various embodiments also provide means for adjusting light distributions dynamically to control light output characteristics by the use of an additional cover lens or glare control films, and by controlling the input signals to the LED board included in the assembly.
Abstract:
A single edge lit lighting module produces bi-lobed light distributions which provide targeted control of light output. The compact form factor of module embodiments having narrow width are particularly well-suited for use in linear lighting fixtures for suspended and downlighting configurations typically used to illuminate floors and/or ceilings. Embodiments of the single edge lit lighting module utilize reflectors in combination with light guides having volumetric light scattering properties and surface features to control peak intensities, output angles, and shapes of the two light output lobes. A variety of light distributions can be achieved including symmetrical distributions conventionally achieved by double edge lit modules. Further embodiments utilize selective alignment of light guide with reflector to achieve different light distributions thereby providing a fixture assembler with more design choices without need of additional components.
Abstract:
Disclosed is a luminaire structure, comprising at least one light guide segment having opposed surface regions and defining a dimension therebetween. At least one edge region with at least one LED array configured to form an edge-lit optical coupling with the edge region. The light guide segment further includes a first sensor passage extending between the opposed surface regions to receive a sensor. At least one of the light guide segment, the first sensor passage and/or the sensor is configured so that light delivered to the light guide segment through the edge-lit optical coupling illuminates the light guide segment with reduced optical disruption by the presence of the sensor in the first sensor passage, when compared with a non edge-lit optical coupling configuration.
Abstract:
A device for mounting a light fixture structure to a ceiling grid. The device includes an anchor structure extending from the light fixture structure, with a pair of arm structures spaced to receive a ceiling grid segment therebetween at an anchor location on the ceiling grid adjacent a lower region of the ceiling grid. The arm structures have respective distal regions configured to be accessible from an upper region of the ceiling grid and a clamp structure configured to traverse laterally relative to the distal regions to couple with the respective distal end regions and thereafter to be transferable between a released position and a locked position. When in the locked position, the ceiling grid segment held between the anchor and clamp structures place the light fixture structure in the mounted position.
