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.

Described herein is a method for mounting a grid hanger assembly of a ceiling system. The ceiling system, in one embodiment, includes a grid support member, ceiling panel, and grid hanger configured to support the grid support member in a suspended manner from an overhead structural support. The grid hanger includes a mounting bracket configured for attachment to the structural support and a hanger member. The hanger member is adjustable in a plurality of selectable mounting positions relative to the mounting bracket, thereby allowing the mounted height of the grid support member to be adjusted in the field. In some embodiments, the hanger member is further angularly adjustable relative to the mounting bracket to avoid installation obstacles.

A suspended ceiling system in one embodiment includes a grid support member and a ceiling panel supported on the member. A resiliently compressible gasket is disposed at the interface between the grid support member and peripheral edge of the panel. The gasket may be fixedly attached to the panel peripheral edge in the factory under controlled conditions before shipment to the ceiling installation site. In one embodiment, the gasket may be adhesively attached to the panel. Mounting the ceiling panel on the grid support member compresses the gasket to preferably form a minimally visible air leakage resistant seal between the air plenum space above the ceiling panels and the occupied space below. This retards air exchange between the spaces which enhances heating/cooling efficiency, noise reduction and allows formation of pressurized clean rooms.

The T-bar includes an elongate rigid spine extending between terminal ends including either a fixed anchor or adjustable anchor for attachment to adjacent T-bars or other supports. An upper heat sink is provided on an upper portion of the spine to enhance heat transfer from the T-bar to air surrounding upper portions of the T-bar. A light housing is provided on a lower portion of the T-bar which is configured to support a lighting module therein, such as a light emitting diode (LED) light. A lower heat sink is provided above this light housing and integrated into a rest shelf which supports ceiling tiles adjacent the T-bar. A power supply is provided which can be removably attached to the T-bar and provide appropriately conditioned power for the lighting module.

A clip for use with a runner of a drop ceiling including a first half with a first support section comprising a first fastener aperture and a first support aperture, a first control section configured to contact the adjacent first ceiling tile, and a first retaining section below the first section comprising a first retaining tab configured to impede the travel of a first side of a bulb. 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.

The present invention discloses a rectangular ceiling module, accessible one by one, that allows the use of larger-than-standard, reduced-thickness formats, with a front face, a rear face and four edges, with corners forming obtuse angles and robust geometry; it is installed from below without surpassing the height of the standard support grid; it rests on the grid by its four edges or sides and leaves the grid hidden. The module is useful as a standard false ceiling, hiding air-conditioning installations, electrical installations, fire-protection systems, low-current systems, etc., located under the slab, mostly in office buildings, while also serving as an element of insulation and/or sound absorption, depending on the material used.

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.

The T-bar includes an elongate rigid spine extending between terminal ends including either a fixed anchor or adjustable anchor for attachment to adjacent T-bars or other supports. An upper heat sink is provided on an upper portion of the spine to enhance heat transfer from the T-bar to air surrounding upper portions of the T-bar. A light housing is provided on a lower portion of the T-bar which is configured to support a lighting module therein, such as a light emitting diode (LED) light. A lower heat sink is provided above this light housing and integrated into a rest shelf which supports ceiling tiles adjacent the T-bar. A power supply is provided which can be removably attached to the T-bar and provide appropriately conditioned power for the lighting module.

In a suspended ceiling a housing is provided including a light located within an interior chamber having a lower opening. The housing includes lateral sides with slots therein which can receive fasteners coupled to ends of other T-bars. Ends of the housing can include fasteners, such as tabs or clips, which attach ends of the housing to adjacent supports, such as other T-bars within the suspended ceiling. In one embodiment, the housing has a constant cross-sectional form. The cross-sectional form can include lateral sides defined by lateral cross-tees with a vertical spine and lateral rest shelf upon which an edge of the ceiling tile can be supported. A central cross-tee can optionally be provided extending down from upper portions of the housing and between diagonal spans on upper lateral portions of the housing. One or more diffusers span the lower opening of the housing.
