Abstract: The present disclosure generally relates to lighting modules, and more specifically, to a configurable linear lighting module for use within a suspended ceiling grid assembly. The configurable linear lighting module is easy to install and comprises a novel linear support element with internal and external support features which is provided with integrated or removable optical assemblies to deliver lighting distributions tailored to optimally illuminate the surface ceiling panels as well as floors, walls and work surfaces below. When installed within a configured ceiling grid assembly the configurable linear lighting module provides novel support features for ceiling panels to be held in-line, above, below or tilted relative to the existing ceiling grid plane. A wide range of useful lighting distributions are achieved by configuring the optical elements and LED light sources supported and aligned by the linear support element.

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.

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.

Abstract: A linear profile support element and ceiling grid lighting module for suspended ceiling systems is provided. The linear profile support element is configured to connect onto a T-bar within a ceiling grid system and has at least two lateral supporting portions to hold an optical device and ceiling panel in position with one or both offset from the ceiling grid plane.

Abstract: A light fixture is provided with increased light output, uniformity of brightness and color and controlled lighting non-lambertian distributions by use of an optical element that functions simultaneously as an outcoupling TIR light guide and a direct throughput lens. It provides typical benefits of an edgelit light guide design including thin forms and shallow depth, extended emitting area, and single or dual peak off axis light distributions particularly useful in applications such as indirect illumination of ceilings, wall washing, aisle lighting, exterior façade lighting and area lighting as well as other lighting applications. 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.
