Abstract
An example configurable lighting device includes a controllable general illumination device configured to output illumination light sufficient for general illumination of an area and a display configured to output light as a representation of an image into the area. The display is co-located with the general illumination device such that an available output region of the display towards the area at least substantially overlaps an available output region of the general illumination device towards the area. The lighting device has a light output surface configured and located such that light output from the general illumination device and light output from the display propagate out via the light output surface. The lighting device also has a noise reduction structure.
