AI Technical Summary

Technical Problem

Curved vehicle glazing with integrated interior lighting systems faces challenges in maintaining uniform illumination due to manufacturing tolerances and the need for precise alignment of point light sources with the curved glass, which is difficult to achieve with existing technologies.

Method used

The use of multiple light modules with an intermediate orientation support allows for the attachment and orientation of light modules relative to the curved glazed element, enabling uniform illumination without the need for curved light modules or precise alignment of point light sources.

Benefits of technology

This solution ensures that point light sources are maintained at an acceptable distance from the glazed element, providing uniform illumination across the curved glazing while simplifying the manufacturing process and reducing assembly complexity.

Abstract

The invention relates to a vehicle glass panel comprising a glazed element (2), comprising a lighting system, with two longitudinal ends of light modules (7, 7') which are attached to a profiled seal (6) by at least one reversible attachment system (100), each of the two longitudinal ends (71, 71') being mechanically connected to an intermediate zone (75, 75') which is located directly between a profiled zone (65, 65') of the profiled seal (6) and a support zone (85, 85') of an orientation support (8), the support zone (85, 85') bearing on the intermediate zone (75, 75'). The invention also relates to a lighting system for such a glass panel, as well as to a method for manufacturing such a glass panel.
