Abstract: An optically transmissive component comprises a light scattering extension portion which can be used within an edgelit light fixture to provides benefits in brightness uniformity and visual appearance by scattering light 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: 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 lighting assembly for use in suspended T-Bar ceiling grid systems is provided comprising two linear lighting modules in a novel parallel arrangement. End plates are used to connect, support, and enclose longitudinal ends of the elongate body of each linear lighting modules at a predetermined and configurable spacing apart while simultaneously functioning as reflective faces for internal and external optical cavities. The configured gap spacing between individual linear lighting modules can be used to house and support components such as additional light sources, acoustic or decorative ceiling panels, HVAC components, or power systems, controls or sensors. Additional end plate embodiments can be configured to allow a T-bar to be placed in the configured gap spacing thereby enabling the mounting of the assembly in-line upon the longitudinal axis of a ceiling grid T-bar.

Abstract: A light fixture with edgelit optical element is configured with an elongate body which retains and aligns optical components in a shallow linear form factor. Embodiments can be installed within a ceiling grid system and provide a fixture height less than that of a ceiling grid T-bar. An edglit optical element with light scattering features produces an extended emitting area for low glare and provides light distributions such as asymmetric and symmetric batwing distributions particularly useful in downlighting and other lighting applications.

The housing body comprises features to retain and align LED boards and the primary optical element. Edge-lit configurations can enable the lighting assembly height to be less than the height of a ceiling grid T-bar. In some embodiments the lighting assembly can also provide structural support within an installed panel system and replace one or more T-bars. The light fixture can be configured to provide low-glare or wide spread “batwing” ambient light or more directional wall wash, task and accent lighting.

Abstract: The present disclosure discloses a lighting arrangement with optical composite that provides, when in operation, more uniform angular light distribution emissions into an environment. Lighting arrangements employing the novel optical composite in conjunction with LED light sources provide direct and indirect illumination with more uniform angular light distribution emissions into application environments. An optically coupled opaque layer suppresses internal reflections of ambient light to improve visual appearance of the optical composite by reducing peak brightness and brightness non-uniformity. In specific embodiments, low visibility matte appearances are achieved that are aesthetically desirable in the “off” (unlit) state. The present disclosure provides a solution to problems of non-uniform angular distribution of light causing visual discomfort and spatial discontinuity in output.
