Title (EN) ARTIFICIAL ILLUMINATION SYSTEM FOR SUN-SKY IMITATION
(FR) SYSTÈME D'ÉCLAIRAGE ARTIFICIEL IMITANT UN CIEL ENSOLEILLÉ
Abstract:
(EN) 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).
(FR) L'invention, selon un aspect, concerne un système d'éclairage artificiel comprenant une pluralité de dispositifs imitant le soleil (ou un ciel ensoleillé) (340) qui sont individuellement conçus comme des dispositifs d'éclairage artificiel destinés à générer de la lumière comprenant une composante de lumière dirigée (314). Chaque composante de lumière dirigée (314) est émise depuis une zone de sortie d'imitation de soleil (342) respective d'un dispositif imitant le soleil (340) respectif de façon à imiter la lumière naturelle provenant du soleil et est caractérisée par un pic dans le profil angulaire de luminance dans une direction d'émission de lumière dirigée (32) et par une uniformité du profil angulaire de luminance sur la zone de sortie d'imitation de soleil. Les profils angulaires de luminance de la pluralité des dispositifs imitant le soleil ont la même direction d'émission de lumière dirigée (32). Le système d'éclairage artificiel comprend en outre un groupe de facettes (400) comprenant au moins une section de facette sélectionnée dans un groupe de sections de facettes, le groupe comprenant une section de facette de blocage de lumière (406), une section de facette de transmission de lumière (404), ou une section de facette (402) imitant un ciel configurée sous la forme d'un dispositif imitant un ciel (320).
