Title: LIGHT-EMITTING GLAZED ASSEMBLY
Abstract:
Light-emitting glazed assembly (100) including at least two transparent elements (2, 3), each including a single rigid substrate made of glass or made of rigid plastic or being laminated, two light sources (5, 6) that are optically coupled, in particular to the edge face, of the two transparent elements (2, 3), which form light guides, means (7, 7') for extracting the guided light, which means are associated with each of said transparent elements (2, 3), respectively, and an optical isolator (4) separating the two transparent elements (2, 3), characterized in that the optical isolator (4) is a vacuum or gas-filled cavity, such as an air-filled cavity, of thickness of at most 10 mm and in that the transparent elements (2, 3) are spaced apart from each other by spacing means (40) that are arranged in proximity to the edge face of the transparent elements, in particular a spacer (41), in particular formed of one or more parts, which parts are preferably arranged over the entire periphery of the assembly.
