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.

A T-bar for a suspended ceiling, the T-bar comprising:
- an elongated rigid spine extending from a first terminal end to a second terminal end;
- an anchor attached to the elongated rigid spine on at least one of the first or second terminal ends;
- a lower portion of the elongated rigid spine including a first rest shelf portion and a second rest shelf portion, the first rest shelf portion extending from the elongated rigid spine in a first lateral direction, the second rest shelf portion extending from the elongated rigid spine in a second lateral direction, the second lateral direction being opposite the first lateral direction, the first and second rest shelf portions and elongated rigid spine forming a cross-sectional form of the T-bar from the first terminal end to the second terminal end, the cross-sectional form of the T-bar configured for placement of the suspended ceiling above the lower portion of the elongated rigid spine;
- a first track slot portion extending downward from the first rest shelf portion;
- a second track slot portion extending downward from the second rest shelf portion;
- a lighting module extending from at least the first terminal end to at least the second terminal end of the elongated rigid spine, the lighting module located below the first and second rest shelf portions and held into position below each the first and second rest shelf portions by placement within the first track slot portion and the second track slot portion;
- and
- wherein the lighting module contains a first side rail and a second side rail, the first side rail of the lighting module resting within the first track slot portion and the second side rail resting within the second track slot portion.
