Abstract: The present invention relates in general terms to a lighting device to simulate natural lighting, thus capable of generating at least two light components with different angular distributions having different correlated colour temperature or CCT. The lighting device to simulate natural lighting thus conceived is able to generate a light with two chromatic components having different angular distributions, however effectively preventing the light at a higher colour temperature (bluish light) from generating glare effects or from giving the environment an unnatural colouring that the natural light of the sky and the sun would not produce.

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 moon appearance generating system (1) is configured for providing an enhanced depth perception to imitate a sky scene, for example, a natural sky scene at night. The moon appearance generating system (1) comprises a luminous device (7) with a primary light emitting area (9) that is configured to provide, when the moon appearance generating system (1) is operated to imitate the sky scene, a two-dimensional spatial profile of a luminous flux density across the primary light emitting area (9) with a mean luminous flux density value of at least 5 lm/m2, a maximum luminous flux density value of less than about 150000 lm/m2, wherein the mean luminous flux density value is at least 2% of the maximum luminous flux density value; and a frame structure (25) providing an exit aperture (5) through which the primary light emitting area (9) is completely viewable from within an enhanced depth perception observation range (33), wherein the exit aperture (5) is associated with an inner frame line (25 A) that surrounds at least an area of 20 cm width and 20 cm height.
