Embodiment Construction

[0031] figure 1 A door panel of a motor vehicle is shown, which door panel has a trim element 1 and separates a cabin 4 of the motor vehicle from an exterior 5 . The main function of the trim element 1 is to provide ambient lighting of the cabin 4, which lighting should be uniform or gradual (eg gently fading off in a certain direction along the cabin element).

[0032] figure 1 The interior trim element 1 is arranged with two side walls 2, 8 between which a closed space 9 is defined. A cylindrical light guide 6 is arranged in the closed space 9 in the example shown. more specifically, figure 1 The cylindrical light guide 6 is located in the hidden corner 13 at the upper end of the closed space 9 .

[0033] The light guide 6 consists of a transparent or translucent material. The light guide extends over all or part of the perimeter 10 of the enclosure 9 .

[0034] The cylindrical light guide 6 , which may in particular be in the form of an optical fiber, is connected to ...

Abstract

The trim element (1) of the invention comprises: - a first wall (2) enabling the passage of light with an outer surface (3) intended to be visible from the passenger compartment (4) of the motor vehicle; - a second wall (8) defining a space (9) with the first wall (2) and one surface (7) of which is capable of reflecting light rays; and - a luminous element (6) positioned inside the space (9) so as to backlight the first wall (2). The luminous element (6) sends a beam of light rays (L) to the second wall (8). The surface (7) diffusely reflects light rays. An inner surface (11) of the first wall (2) has light-reflecting properties such that the incident light rays on said inner surface (11) are partially reflected to the second wall (8) and partially emitted across the first wall (2).

Description

technical field [0001] The invention relates to a luminous interior trim element, in particular for a motor vehicle, comprising: [0002] - a first wall through which light passes, said first wall having an outer surface for being visible from a cabin of a motor vehicle; [0003] - a second wall defining a space with the first wall, and a surface of the second wall opposite the first wall is capable of reflecting light; and [0004] - Lighting means comprising light emitting elements located in said space in order to backlight said first wall. Background technique [0005] Such a luminous interior trim element is known from document FR 2877896 A1. Document WO 2007 / 003663 A1 gives another example of a luminous interior trim element. [0006] A luminous interior trim element known from FR 2877896 A1 makes it possible to illuminate the cabin of a motor vehicle. Illumination is ensured by light sources arranged inside the box. The box comprises a rear wall and a wall facing...
