Patent number: 11067251Abstract: An embodiment of an illumination device comprising a broad band artificial light source and a non-liquid chromatic diffuser transparent to visible light comprising a dispersion of elements of nanometrical dimensions of a first material with of certain refractive index in a second material with different refractive index, wherein the light is scattered producing a separation and different distribution between cold and hot components of the light originally produced by the source, according to a scattering process in “Rayleigh” regime. The device allows illumination effects similar to those of natural outdoor environments to be reproduced in indoor environments.Type: GrantFiled: May 17, 2019Date of Patent: July 20, 2021Assignee: CoeLux S.r.l.Inventors: Paolo Di Trapani, Marta Cecilia Pigazzini
