Abstract

A luminous glazing is provided that includes a pane and a light guide. The pane has two opposite faces and is transparent in the visible spectrum. The light guide has a core surrounded by a cladding so that the core is capable of guiding light along the longitudinal extension of the light guide. The light guide includes a light scattering element so that when light is injected into one of the end faces if the light guide, the light guide is a side-emitting light guide and forms a linear light source. The light guide extends along the faces and is disposed on one face such that the light scattering area is spaced apart from the face and so that light guided in the core, scattered, and laterally exiting from the light guide enters the transparent pane through the face and is be transmitted through the pane to the opposite face.
