A system and method for controlling light shading and thermal insulation in a light transmissive structure is disclosed. An array of adjacently-positioned, inflatable first tubes is provided, each of the first tubes being inflatable to abut an inflated adjacent first tube. Each of an array of inflatable second tubes is nested within, and inflatable independent of, one of the first tubes. Each of the second tubes is connected to one of the first tubes such that when not inflated, each of the second tubes is flattened within the one of the first tubes. When inflated, each of the second tubes abut an inflated adjacent second tube via first tubes. The first tubes are preferably clear, while the second tubes are made of a reflective material.

A lighting system to simulate a window open to the sky and comprising an optical system including: a visible optical source, which emits visible optical radiation; and a chromatic optical device, which includes a diffusion region and defines a first emission surface arranged downstream of the diffusion region. The chromatic device receives the visible optical radiation and generates, on the first emission surface, a visible output beam, which has an angular luminance profile that exhibits a peak with FWHM below 20 in two planes, mutually orthogonal and containing the direction of maximum luminance. In each point of the first emission surface, the visible output beam comprises a direct component, emitted in the direction of the luminance peak, and a diffuse component emitted at angles that differ by more than 40 from the direction of the direct component. The CCT of the diffuse component is at least 1.2 times higher than the CCT of the direct component. The lighting system also includes an infrared source, which defines a second emission surface and emits, downstream of the second emission surface, an infrared output beam substantially without visible components.
