Abstract: The examples relate to various implementations of a single software configurable lighting device, installed as a panel, that offers the capability to appear like and emulate a variety of different lighting devices. Emulation includes the appearance of the lighting device as installed in the wall or ceiling, possibly both when lighting and when not lighting, as well as light output distribution, e.g. direction and/or beam shape. Specific examples in this case combine a display device with a spatial light modulator or use angled light sources in each pixel, possibly with a settable beam shaper associated with one or more of the emission pixels.
