Abstract
The invention relates to a unit with variable optical properties, which combines at least one system with variable light transmission/absorption, especially of the electrochromic or viologen type, with at least one system with variable light diffusion, especially of the optical valve type or with liquid crystals. The systems are electrically control-driven in order to modulate in a decorrelated manner the light transmission level and the light diffusion level of the unit.
