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.

Abstract: Various light fixtures are provided for mounting within and below suspended grid ceilings incorporating T-bars and ceiling panels. The light fixtures comprise a double or single edgelit planar or wedge shaped optical element that functions simultaneously as an outcoupling TIR light guide and a light scatterer or direct throughput lens. It provides a number of benefits because of its edgelit design including; thin forms and shallow depth, extended emitting area and controlled lighting distributions from one or two light guide faces. Additionally, areas typically dedicated to bezels or edge reflectors can be greatly reduced or eliminated due to decreased hotspotting to provide a fixture face with very high percentage of light emitting area. Embodiments are described for direct, indirect, and direct indirect configurations. The embodiments provide increased light output, uniformity of brightness and color and controlled direct and indirect lighting distributions and with single or dual off axis intensity peaks.

Abstract: A optically transmissive component is configured within a light fixture to provide benefits in brightness uniformity and visual appearance with the use of a light scattering extension portion that provides light scattering of light emitted from near an input edge of a light guide or other edgelit optical element. The sequential propagation of light through both the extension portion and main portion of the optically transmissive component significantly reduces the higher brightness and uneven “hotspotting” type visual defects typically produced near the input edge of an edgelit optical system. With appearance constraints removed or reduced, edgelit light fixtures with higher output, higher efficacy, and/or simplified edgelit optical components are enabled. Embodiments include the use of the extension portion of the optically transmissive component extension to mechanically position and retain an edgelit optical element within a light fixture.

Abstract: 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.
