1. An apparatus, comprising:

  • a general illumination light source configured to emit general illumination light for illuminating a space;

    an optical coupling configured to receive the general illumination light emitted by the general illumination light source and to direct general illumination light emitted by the light source toward a light output interface of the optical coupling;

    an optical array comprising optical passages there through, the optical passages being coupled to receive general illumination light via the light output interface of the optical coupling, wherein;

    a configuration of the optical coupling together with a configuration of the optical passages through the optical array define a distribution of general illumination light output of the apparatus into the illuminated space, andthe distribution of general illumination light output includes near-field shadow regions formed between outputs of two or more of the optical passages; and

    display light emitters mounted at locations substantially corresponding to at least some of the near-field shadow regions of the optical array and being oriented to emit additional light into the space to be illuminated, wherein;

    the display light emitters are configured to present pixels of light for presentation of an image, andthe apparatus is configured to simultaneously display a portion of the image via the display light emitters and emit the general illumination light from the general illumination light source via the optical passages.
