Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A T-bar type support extends in elongate form and is configured, such as with a spine and rest shelf, for supporting edges of ceiling tiles thereon within a suspended ceiling system. A lighting module is suspended below other portions of the T-bar. The T-bar also includes a reflector plate above the body which extends at least partially laterally and below where the ceiling tiles are supported. A lighting source within the lighting module shines light upwardly which then reflects off of the reflector plate and down into an interior space beneath the suspended ceiling. Legs preferably suspend the lighting module below the reflector plate, with the legs preferably at ends of the T-bar, and with open space between the legs, so that nothing obstructs light shining from the lighting source up against the reflector plate and then down into the interior space beneath the ceiling.

Abstract: In a dropped ceiling assembly system elements are provided which include an elongate planar shelf held below an elongate spine. The shelf has lateral edges which can support edges of a ceiling tile resting thereon. This spine is configured to be held in position either adjacent to spines of other elements within a dropped ceiling or from above, such as by suspension wires passing through suspension holes in the spine. A compartment is provided on an underside of the shelf which is sized and shaped to receive and hold at least a portion of a loudspeaker therein. The loudspeaker mounting system is thus integrated into the shelf which also acts to hold ceiling tiles within a dropped ceiling.

Abstract: A housing is located at least partially beneath a rest shelf of a T-bar or other support for ceiling tiles. A spine extends up from the rest shelf. The housing includes an opening with a centerline which extends at least partially laterally. A light source such as an LED within a recess of the housing shines out of the opening along the centerline in an at least partially lateral direction. A diffuser is preferably provided spanning this opening. The housing preferably includes a front wall opposite a rear wall, with the rear wall larger than the front wall and with the opening in the housing extending between lower portions of the rear wall and lower portions of the front wall. Heat transfer fins on an upper surface of the rest shelf and upper end of the spine are preferably provided to assist in heat dissipation.
