Clouds for artificial skylights and windows

Abstract

The invention provides a light generating system (1000) comprising an enclosure unit (400), a first light generating device (110), and one or more objects (440), wherein: the first light generating device (110) is configured to generate first device light (111) comprising visible light, wherein the visible light at least comprises blue light; the enclosure unit (400) comprises an enclosure wall (420) and an enclosure window (430) enclosing an enclosure space (410); wherein the enclosure wall (420) is configured to absorb at least part of the first device light (111) reaching the enclosure wall (420); and wherein the enclosure window (420) is translucent for the first device light (111) and scatters at least part of the blue light; the first light generating device (110) and the enclosure unit (400) are configured such that (i) the first device light (111) is provided in the enclosure space (410), and (ii) part of the first device light (111) escapes from the enclosure space (410) via the enclosure window (430); the one or more objects (440) are configured in the enclosure space (410) and are configured to reflect at least part of the first device light (111) reaching the one or more objects (440); the enclosure unit (400), the first light generating device (110), and the one or more objects (440) are configured such that at least part of the first device light (111) reaching the one or more objects (440) only reaches the one or more objects via reflection at the enclosure window (430).
