    Abstract: In an aspect, an artificial illumination system comprises a plurality of sun (or sun-sky) imitating devices (340) that each are configured as an artificial illumination device for generating light comprising a directed-light component (314). Each directed-light component (314) is emitted from a respective sun imitating output area (342) of a respective sun imitating device (340) for imitating the natural light from the sun and features a peak in the luminance angular profile along a directed-light emitting direction (32) and a uniformity of the luminance angular profile over the sun imitating output area. The luminance angular profiles of the plurality of the sun imitating devices have the same directed-light emitting direction (32). The artificial illumination system comprises further a bezel cluster (400) comprising at least one bezel section selected from a group of bezel sections, the group comprising a light blocking bezel section (406), a light transmitting bezel section (404), or a sky imitating bezel section (402) configured as a sky imitating device (320).

    Abstract: In an aspect, a combined system (300) comprises a sun-sky imitating device (310) that is configured as an artificial illumination device (20) for generating light with a luminance profile and an appearance, which feature a directed-light component (314) and a first diffused-light component (316) that are emitted from a sun-sky imitating output area (312) for imitating the natural light from the sun and the sky, respectively, and the sun-sky imitating output area (312) has a transversal dimension (D310) of at least 7 cm, wherein the transversal dimension as the longest line segment joining two points of a perimeter of the sun- sky imitating output area (312). Moreover, the combined system (300) comprises a sky imitating device (320) that is configured as an additional diffused- light emitter to emit a second diffused-light component (326) from a sky imitating output area (322) for imitating the natural light from the sky only.
