Abstract
A lighting system (1) for in particular forming a room edge (12) of a room comprises an enlarged sky-perception providing unit (2) with a light transparent panel (3) and a mirror unit (13) with a reflective face (13A) forming an inner edge (14), the lighting system further comprises a light source (41) configured to emit a direct light beam (43) through the light transparent panel (3) onto the mirror unit (13) such that the transmitted portion (9) of the light beam is reflected completely by the reflective face (13A), thereby creating a reflected direct light beam (17) in particular for imitating a sun beam.
Claims15
An enlarged sky-perception providing unit (2) for a sun-sky imitating lighting system (1) in inner edge configuration in particular for forming a room edge (12), the unit (2) comprising:
- a light transparent panel (3) configured to emit diffused light (7) from a front face (3A), and
- a mirror unit (13) with a reflective face (13A) positioned next to the light transparent panel (3) to form an inner edge (14) together with the light transparent panel (3),
- wherein the size of the light transparent panel (3) is smaller than the size of the mirror unit (13).
The unit (2) of any one of the preceding claims, wherein
- the light transparent panel (3) comprises a plurality of nanoparticles embedded in a matrix and configured to provide for a direct transmission of visible light that is larger in the red than in the blue and for a diffuse transmission that is larger in the blue than in the red, and/or
- wherein the mirror unit (13) is positioned next to the light transparent panel (3) and in particular in proximity, specifically at a distance smaller than half, a third, and/or a quarter of the average width of the panel.
The unit (2) of any one of the preceding claims, further comprising
- a transition unit (29) forming the transition between the front face (3A) and the reflective face (13A), and in particular extending along the neighboring border regions of the front face (3A) of the light transparent panel (3) and of the reflective face (13A) of the mirror unit (13) and/or extending along a very inner edge portion (14′) of the formed inner edge (14).
