Abstract: A light fixture with a single edge lit optical assembly produces various light distributions which provide targeted control of light output with peak intensity that is non-normal to the light guide output face. The compact form factor of the light fixture embodiments having narrow width are particularly well-suited for use in linear lighting applications requiring suspended, surface and recessed installations typically used to illuminate walls, floors and/or ceilings. The light fixture can also be selectively configured and oriented during assembly and installation to achieve various lighting distributions. Optical components within the light fixture are typically positioned and retained in optical alignment with internal support features of a linear housing. The optical assembly typically includes LED board, light guide, and one or more reflectors, and an optically transmitting component further providing a fixture assembler a range of design choices.

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: A linear lighting assembly is disclosed which produces tailored light distributions valuable in many illumination applications. The linear lighting assembly comprises a unique light scattering optical element within a single edge lit linear lighting module housing configured to fit within a linear light fixture housing, both housings capable of being fabricated in a continuous extrusion process and cut to length as need for specific linear lighting assembly lengths. Light distributions attainable using the invention include, but are not limited to, symmetric and asymmetric bi-lobed “batwing” distributions for wide area direct and indirect lighting, and tilted or asymmetric distributions for perimeter lighting. It is also possible to achieve more rounded and symmetric distributions by an additional diffuser as a cover lens. The invention is particularly well-suited for linear lighting fixtures that are surface mounted, suspended or recessed.
