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.

A multifunctional lighting assembly is configured with optical components such as lenses and reflectors mounted within an elongate body that serves as a cross tee within a T-bar grid arrangement. Protrusions of the elongate body are used to position optical components and embodiments provide for the slidable mounting of optical components. Further embodiments provide for the support of ceiling panels within a suspended ceiling system, connection to a structural ceiling, and inclusion of further components such as sensors, electronic controllers, and wireless modules.

A multifunctional lighting assembly is configured with an elongate body that serves as a cross tee within a T-bar grid arrangement and has at least one connecting member with a flexible PCB strip that provides bridging of a T-bar to make electrical connections between multifunctional support assemblies without need of cutting or significant displacement of ceiling tiles of the T-bar grid arrangement. Further embodiments provide for the support of ceiling panels within a suspended ceiling system, connection to a structural ceiling, and inclusion of further components such as light sources, optical components, sensors, electronic controllers, and wireless modules.

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. By selectively applying electrical power to individual light source channels it is further possible to electrically control lighting distributions. As such the configurable linear lighting module provides both aesthetically pleasing features and useful lighting distributions. Furthermore, illustrated embodiments of ceiling grid assemblies comprising one or more of the configurable linear lighting modules demonstrate how both appearance and lighting distributions can be controlled to meet aesthetic and lighting design requirements.
