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 dimens...
A sunlight-based projector system (3) is disclosed for providing a direct light beam (5). The projector system (3) comprises a sunlight receiving unit (9) with a collector system (13), a plurality of optical fibers (15), and a plurality of fiber output channels (44). The collector system (13) collects natural outdoor light, and couples the collected light into the plurality of optical fibers (15). The projector system (3) comprises further a sunlight forming unit (11) with a plurality of opti...
A light source (25) for emitting collimated light (29) in particular for a large area luminaire (21) comprises a light guide unit (43) for guiding light by total internal reflection. The light guide unit comprises a plurality of localized light source regions (57) at a main front face (55A) for having light pass there through. The light source (25) further comprises a plurality of light emitting units (41) for emitting light into the light guide strips (91) through respective portions of the ...
In an aspect, a lighting system (1) comprises a lighting unit (11) with a light source (31) and a dichroic light exiting surface (15), wherein the lighting unit (11) is configured for emitting dichroic light from the dichroic light exiting surface (15). The emitted dichroic light includes a directional light portion (37) of direct light (17) and a diffused light portion (39) of diffused light (19) with a another larger correlated color temperature. The lighting system further comprises an app...
An illumination system (1, 100, 200, 300) for providing an optically widened perception comprises a reflector unit (6, 206, 306) comprising a reflective surface (8A) and a luminous layer (10, 210, 310) for homogenously emitting diffuse light at a first color, the luminous layer (10, 210, 310) extending in front of the reflective surface (8A) and comprising a visible front area section (10A, 210A, 310A) of the reflector unit (6, 206, 306), which extends up to a first boundary (12A, 310A) and t...
