A motor-vehicle light-emitting module includes a plurality of light sources configured to emit light rays, and a plurality of cavities each having a first aperture and a second aperture opposite the first aperture. Each light source is associated with one cavity, so that at least part of the light rays emitted by each light source enters via the first aperture of the associated cavity and exits said associated cavity via the second aperture. The light sources emit radially.

Light-emitting motor-vehicle module

A lighting device including at least one surface light source and a support for this, wherein the surface light source includes a fixing element which has a T-shaped cross-section, and wherein the support includes a receiving part for the fixing element, a cross-section through the receiving part having a shape complementary to the cross-section of the fixing element. In the lighting device according to the invention, the fixing element includes an upright and a head, the upright extending from a lower face of the surface light source, the upright and the head together with this lower face delimiting at least one engagement groove for the receiving part of the support. Application to motor vehicles.

Lighting device and system for motor vehicle using a surface light source

A light-emitting module for a motor vehicle. The light-emitting module includes a substrate including a curved main section, light-emitting elements arranged on a face of the substrate and configured to generate light rays, a curved screen arranged facing the face of the substrate and away from the face, an area of the screen being suitable for being illuminated by the light rays emitted by the light-emitting elements, the screen having scattering properties with respect to the light emitted by the light-emitting elements, each light-emitting element being arranged on the substrate in a given zone, each light-emitting element furthermore being arranged to emit the corresponding light rays in a main emission direction that is angularly offset from a local direction that is normal to the substrate in the given zone.

Light-emitting module for a motor vehicle

The invention relates to a process for obtaining a light-scattering assembly in particular for a motor vehicle, the light-scattering assembly comprising a part including first and second sections. The process includes forming, by injection molding, the first section of the light-scattering assembly, the first section forming a transparent scattering screen having microstructures obtained by injection molding and configured to scatter light passing through said first section, and forming, by injection molding, the second section, the second section being devoid of microstructures obtained by injection molding and configured to scatter light. The second section has an external region extending around at least some of the perimeter of the first section, the external region extending beyond a peripheral portion of the first section [and away from the first section, the first and second sections being formed in contact with each other and being united with each other.

Process for obtaining a light-scattering assembly in particular for a motor vehicle

A lighting device, in particular for a motor vehicle, including a substrate; light sources of the side-emitting LED type, which are placed on the substrate and which illuminate in main directions that are orientated along the substrate; and a screen placed so as to receive the light rays emitted by the light sources. The substrate includes windows and the lighting device furthermore includes reflective surfaces that are placed facing the windows so as to reflect, toward the screen, a portion of the light rays emitted by the light sources.

Lighting device of small thickness and producing uniform illumination

A light emission module, in particular for a motor vehicle. The module includes a substrate comprising a curved main portion extending in a longitudinal direction. A plurality of electroluminescent elements is arranged on the substrate and configured to emit light rays when supplied with electrical energy. The electroluminescent elements are distributed along the longitudinal direction, and a control assembly suitable for regulating the electrical energy supplied to the electroluminescent elements. The control assembly has a mode of operation in which the control assembly is configured to supply the electroluminescent elements with respective electrical energies and/or powers determined at least as a function of respective main directions of light emission of the electroluminescent elements to obtain at least two maximum light intensities emitted by the electroluminescent elements in the corresponding main direction of emission which are different along the longitudinal direction of the substrate.
