A dome light assembly that includes a reflective surface facing an interior; a light-diffusing element over the reflective surface having a plurality of corresponding opposed edges and LED sources; and a controller for directing the sources to transmit a plurality of light patterns from the element
A dome light assembly that includes a reflective surface facing an interior; a light-diffusing element over the reflective surface having a plurality of corresponding opposed edges and LED sources; and a controller for directing the sources to transmit a plurality of light patterns from the element into the interior based at least in part on a plurality of inputs. Further, each source is configured to direct incident light into the corresponding edge. These light patterns include natural light and other light patterns. The inputs include manual inputs, weather inputs, exterior light sensor inputs, temporal inputs and global positioning system inputs.
