Abstract
For a luminaire offering both illumination and display functionality, control strategies coordinate illumination/image output so as to mitigate interference of the illumination light output with aspects of the displayed image light output. In one example, when displaying a selected image with one or more white regions in the image, a sufficient number of selected white illumination emitters can be ON or operating in a low power state in the white regions while the rest of the luminaire output area can display the non-white elements of the image with aligned illumination emitters turned OFF. In another example, an image is displayed in a selected region of the luminaire output while illumination emitters within the area displaying the image are OFF or operating in a low power state, but illumination emitters along other parts of the luminaire output are turned ON.
