The present disclosure generally relates to lighting assemblies, and more specifically, to a configurable modular lighting assembly for use within a ceiling grid system. The lighting assembly is easy to install and delivers lighting distributions tailored to optimally illuminate the surface ceiling panels as well as floors, walls and work surfaces below. The configurable modular ceiling grid lighting assembly comprises both standard ceiling grid components such as T-Bar, ceiling panels and suspension cables as well as novel linear support elements with integrated or removable optical assemblies and covering elements. When installed the ceiling grid lighting assembly provided further comprises ceiling panels that are held in-line, above, below or tilted relative to the existing ceiling grid plane and as such provide both aesthetically pleasing features and useful lighting distributions. Further embodiments illustrate how both appearance and lighting distributions can be controlled by selectively applying electrical power to individual light source channels.

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.

The clip further includes a second half with a second support section comprising a second fastener aperture and a second support aperture, a second control section configured to contact the adjacent second ceiling tile, a second retaining section comprising a second retaining tab configured to grip a second side of the bulb, the second side opposite the first side, a fastener to couple the first half to the second half, a support element to couple the clip to an external support.

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. In embodiments having the ceiling panel on an upper lateral support portion, a recessed volume is created in the ceiling grid system which functions as an optical cavity for light from an optical device mounted at the lower lateral supporting portion. With a ceiling panel mounted on the lower lateral supporting portion, the panel is dropped with respect to the ceiling grid plane and the optical device can be aligned at an upper lateral supporting portion horizontally, for example to project light onto a surrounding ceiling panel and provide indirect lighting from the ceiling. Ceiling panels mounted on the lateral supporting portions can be either standard ceiling grid panels or panels alternatively configured for specific appearance or reflectance properties. Various embodiments are described that provide a range of useful mounting options for both the optical system and ceiling panel, including configurations with tilted ceiling panels. Multiple linear supporting elements can be used to create an enhanced three-dimensional appearance to the suspended ceiling system as well as interesting features such as fully or partially illuminated panels, cavities, coves or edges. Ceiling grid lighting module embodiments integrate the linear profile support element with an optical device for pre-configured light distribution and form factor that can be easily installed in a ceiling grid system.

A ceiling grid lighting assembly for use in suspended ceiling systems is provided with multiple linear lighting modules in parallel arrangement. End plates are used to connect, support, and enclose longitudinal ends of the elongate body of each linear lighting modules while simultaneously functioning as reflective faces for optical cavities. A configured gap spacing between individual linear lighting modules can be used to house and support components such as additional light sources, acoustic or decorative panels, HVAC components, or power systems, controls or sensors. The end plate can also 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. Embodiments of linear lighting modules are presented comprising LED light sources, light guides and diffusers housed within the elongate body. The light guides may be edgelit from one or two sides and aligned horizontally or tilted relative to the ceiling grid plane.
