Abstract
The examples relate to various implementations to enable simultaneous controllable lighting distribution and a wide angle image light output from areas of a luminaire. An example of such a luminaire includes image light emitters and an array of general illumination light emitters for general illumination. A grid structure that has a supporting grid of rows and columns with intersection points and transparent sections or gaps is used to maintain a spaced arrangement of the general illumination light emitters and the image light emitters. Each of the transparent sections is bounded by individual structural members of the grid meeting at individual intersection points. In a specific example, image light emitters are located at intersection points of the grid structure. The general illumination light emitters are optically coupled for emitting general illumination light through the transparent sections of the grid.
