A ceiling system is provided for use in a building space. The ceiling system has an open cell grid structure and is attached to a support structure of the building via hanging hardware. The open cell grid structure is constructed of a plurality of first panels attached to the hanging hardware, a plurality of second panels attached to the plurality of first panels, and a plurality of third panels attached to the plurality of second panels. The first, second, and third panels are attached via a plurality of slots which allow secure engagement and utilize gravity to retain them in the assembled condition. Beneficially, the plurality of second panels and the plurality of third panels are free of hanging hardware.

An acoustic ceiling tile and a dynamic acoustic ceiling system that includes multiple ceiling tiles that can be quickly and easily installed onto ceiling structures utilizing attached or embedded magnetic assemblies to provide an aesthetically pleasing image, such as an fluctuating image, along with a reduction in unwanted noise or room acoustics, wherein the attached or embedded magnetic assemblies are configured to be removed from the ceiling tile, and then configured to be easily placed or located onto a different location on the ceiling tile as needed, to allow for optimal installation of the ceiling tile onto the ceiling structure.

The partially lit T-bar includes a spine with a rest shelf at a lower portion thereof. The rest shelf supports adjacent ceiling tiles. The under surface of the rest shelf includes a lighting module on a portion and a plain unlit undersurface on other portions. Additional T-bars which are shorter, and typically fully lit or fully unlit and half the length of the partially lit T-bar are also provided which can attach at ends or near a midpoint of the partially lit T-bar and typically perpendicularly thereto. A great variety of lighting patterns in a dropped ceiling is thus facilitated. Each of the T-bars preferably also includes a heat sink on an upper portion of the spine and also preferably a lower heat sink on an upper portion of the rest shelf. Heat associated with the light element of the T-bar can thus be drawn away from a space below the ceiling.

A ceiling system in one embodiment includes an overhead support grid comprised of a plurality of intersecting grid support members and a ceiling tile mountable to the grid. Retaining clips support the ceiling tile from the grid which may be concealed from view. The retaining clips each include a cavity that receives a grid support member and a pair of resilient mounting elements configured to lockingly engage a support member. The mounting elements are laterally movable in response to inserting the support member into the cavity of the retaining clip. In one embodiment, the movable elements include locking tabs which create a snap-fit interlock with the grid support member for securing the ceiling tile to the grid.

A ceiling system in one embodiment includes first grid support members arranged in parallel spaced apart relationship. A pair of elongated lighting support members is arranged in parallel with the first grid support members. The lighting support members are spaced apart and define an axially elongated lighting opening. A lighting spacer bracket is connected between and supports the lighting support members from an overhead building support structure. In one embodiment, the bracket is configured to define a downwardly open cavity for at least partially receiving a lighting module therein. A lighting module is positioned in the lighting opening and supported by the lighting support members. In one embodiment, the lighting module may be a digital linear lighting module.
