摘要： 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. Various embodiments also provide means for adjusting light distributions dynamically to control light output characteristics by controlling the input signals to the LED board included in the assembly.

摘要： 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 which is aligned with one or more LED light sources along one of its edges and works in combination with configured reflective surfaces. 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's unique single edge lit construction provides the means for achieving the lighting distributions without the need for conventional two lit edges and within a compact form factor with narrow width. The invention is particularly well-suited for linear lighting fixtures that are surface mounted, suspended or recessed. Various embodiments also provide means for adjusting light distributions dynamically to control light output characteristics by controlling the input signals to the LED board included in the assembly.

摘要： A lighting assembly with a single edge lit optical configuration produces various asymmetric 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 lighting assembly 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 lighting assembly can also be selectively configured and oriented during assembly and installation to achieve various lighting distributions. Optical components within the lighting assembly are typically positioned and retained in optical alignment with internal support features of a linear housing. The optical configuration typically includes LED board, light guide, and one or more reflectors, and an optically transmitting component providing further control of the lighting distributions and a broader range of design choices. A variety of asymmetrical and symmetrical light distributions can be achieved with one or more peak intensities. Further embodiments utilize selective alignment of the light guide with one or more reflectors to achieve different light distributions.

摘要： A single edge lit lighting module produces bi-lobed light distributions which provide targeted control of light output with peak intensity that is non-normal to the lighting module output face. The compact form factor of module embodiments having narrow width are particularly well-suited for use in linear lighting fixtures for suspended, surface and recessed lighting configurations typically used to illuminate walls, 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 bi-lobed distributions conventionally achieved by double edge lit modules. Further embodiments utilize selective alignment of light guide with reflector to achieve different asymmetric light distributions. The single edge lit lighting module incorporates a housing, LED board, light guide and reflector, and can further incorporate an optically transmitting lens over its output face and provides a fixture assembler with a range of design choices without need of additional components.

摘要： 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.
