Claims26
A glazing comprising:
- a sheet of transparent glass with a first main face, a second main face, the first and second main faces being parallel to each other, and a rim;
- a flat waveguide with a first face, a second face, an injection rim and a beveled rim, opposite the injection rim;
- a light source positioned facing the injection rim of the flat waveguide and having sufficient power to inject therein a light flux of at least 35 lumens (lm),
- the flat waveguide being fixed via the second face to the first main face of the sheet of transparent glass to provide an assembly that is transparent from the first face of the flat waveguide to the second main face of the sheet,
- wherein the injection rim of the flat waveguide and the rim of the sheet of transparent glass are offset relative to one another so that the light source is directly attached to the first main face of the sheet of transparent glass between the injection rim of the flat waveguide and the rim of the sheet of transparent glass,
- wherein the beveled rim and the first face of the flat waveguide form a point with an acute angle of between 10° and 80°,
- wherein the beveled rim is arranged to face the first main face of the sheet, and
- wherein a width of the beveled rim extends from the first face to the second face of the flat waveguide and the beveled rim remains beveled along said width of the beveled rim.
