Problems solved by technology

Nevertheless, this lighting system does not perfectly reproduce the perspective effect experienced by the observer when there is a window facing the sky
Specifically, such lighting systems cannot induce the viewer's visual perception of an infinite depth of field

Embodiment Construction

[0024] As mentioned above, figure 1 An artificial lighting system 1 is shown, which will be referred to simply as lighting system 1 from now on.

[0025] Specifically, the lighting system 1 comprises a first light source 2, preferably a directional light source, designed to emit light with an emission solid angle smaller than 4π sr. Furthermore, the first light source 2 emits light in the visible region of the spectrum, ie has a wavelength of 400 nm to 700 nm. Furthermore, the first light source 2 emits light (visible electromagnetic radiation) with a spectrum Δλ width preferably higher than 100 nm, more preferably higher than 170 nm. The spectral width Δλ may be defined as the standard deviation of the wavelength spectrum of the first light source.

[0026] The lighting system 1 also comprises a first diffusing panel 4, for example in the shape of a parallelepiped. Specifically, the first diffusing panel 4 has first surfaces S parallel to each other 1 and the second surfa...

Abstract

An embodiment of a lighting system for illuminating an environment with a lighting that simulates natural lighting includes: a first light source which emits a beam of visible light; a diffused-light generator delimited by an inner surface, which receives the light beam, and an outer surface, the diffused-light generator being at least partially transparent to the light beam. The diffused-light generator transmits at least part of the light beam and emits, through the outer surface, visible diffused light, the correlated color temperature of the transmitted light being lower than the CCT of the visible diffused light. The lighting system includes a dark box which hosts the first light source, the dark box being optically coupled to the environment via the diffused-light generator.

Description

technical field [0001] The invention relates to an artificial lighting system. In particular, the present invention relates to an artificial lighting system that simulates natural lighting. This lighting system can illuminate the room it is in in a very similar way to what would happen in the same room with the aperture open with the blue sky and the sun on the other side. Background technique [0002] It is currently known to provide a variety of artificial lighting systems for closed environments ("indoors"), the aim of which is to improve the visual comfort experienced by the user. In particular, lighting systems that simulate natural lighting, ie the type of lighting available in open environments ("outdoors"), are known. A well-known property of outdoor lighting depends on the interaction between the light produced by the sun and the earth's atmosphere. [0003] In the pending European patent application EP 2304480 filed by the present inventors, a lighting system co...
