| abstract |
The present invention relates to a light laminated structure (100) comprising: a first transparent and plane substrate (1), of optical index or given, a second flat substrate dyed in the mass (1 "), a lamination interlayer (5) between the first and second substrates, a porous layer (2 ") forming an optical separator, deposited on the laminating interlayer or on the first substrate, the layer being of optical index n2, the difference n2 - ni being greater than or equal to 0.1, a light source (6) coupled to the edge of the first substrate, an inner backscattering network (7) between the porous layer and the first substrate, and / or an external diffusing grating on the outer face of the first substrate. |
