AI Technical Summary

Technical Problem

In the prior art, it is difficult to realize the interior decorative materials of the vehicle passenger compartment under different lighting conditions. It can not only provide sufficient light intensity during the day to reveal the material patterns and textures, but also avoid excessive lighting disturbing the driver or passenger at night.

Method used

At least two light source configurations are adopted, one for backlighting and the other for indirect lighting, through or reflected on the decorative elements, providing adaptive lighting during the day and at night, respectively.

Benefits of technology

Adaptive lighting of passenger cabin decorative elements under different lighting conditions is achieved, providing sufficient light intensity during the day to show material characteristics, reducing light intensity at night to reduce interference, and avoiding excessive lighting.

Abstract

A lighting module (4) for lighting a passenger compartment of a vehicle comprises at least one light source (22, 24) configured to emit light and a decorative element (12), the at least one light source being configured to emit light, the decorative element being arranged in a path of light emitted by the at least one light source (22, 24), the lighting module (4) comprising at least one first light source (22) and at least one second light source (24), the first light source being configured to emit light on a first face (42) of the decorative element (12), the second light source being configured to emit light on a second face (14) of the decorative element (12) opposite to the first face (42). The light emitted on the second face (14) generates indirect lighting, and the light emitted on the first face (42) intended to pass through the decorative element (12) from the first face to the second face generates direct lighting or backlighting.
