Abstract (en)
[origin: WO2016081019A1] 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.
