Abstract:
1. A ceiling lighting system comprising: a ceiling tile having one or more recesses extending at least partially through ceiling tile, the ceiling tile having an aperture opening; a light distributing engine including a light emitter, a heat sink, and light distributing optics, the light distributing optics collecting the light from the light emitter and redirecting the light into a directional beam of output illumination, wherein an output aperture of the light distributing engine is aligned with the aperture opening of the ceiling tile so that the directional beam of output illumination is substantially transmitted to the space below the ceiling tile; an electronic circuit configured to transmit and control electrical currents passing to and from the light distributing engine, the electronic circuit including a voltage regulation circuit, an electric current control circuit, and a control signaling circuit, the electric voltage regulation circuit providing regulated DC voltage levels for the electric current control circuit and the control signaling circuit, the control signaling circuit including a control signal receiver circuit arranged to receive and process control signals broadcast by a master controller outputting control instructions to the electric current control circuit, and the control signaling circuit further including a control signal transmitter circuit arranged to broadcast informational signals at regular time intervals to the master controller corresponding to first electrical signals; one or more on-tile power transfer elements associated with the electronic circuit, one or more affixation elements, the one or more affixation elements used to affix the electronic circuit, the one or more on-tile power transfer elements, the one or more electrical power access terminals, and the light distributing engine to each other and/or to the one or more recesses of the ceiling tile.
