    Abstract: An optical system and an interior lighting device for a motor vehicle including a light source coupled to such an optical system. The optical system includes a first portion of an optical assembly that allows a real image of the light source to the enlarged and projected into proximity to a diffuser of the optical system. The optical assembly also includes a second portion that plays the role of a projecting optic to project out of the optical system a real image of the of the light source formed in proximity to the diffuser. The optical system allows a luminance of the light source of the interior lighting device to be decreased while preserving its pixelization, allowing light sources based on light-emitting diodes and driven with a high-amperage electrical current to be used in motor-vehicle passenger compartments without any risk to the occupants.

    Abstract: The lighting device for a vehicle has two light sources and a wavelength conversion device excited by the combination of the radiations from the two light sources. A first light source is associated with a scanning system projecting, by scanning, a first light radiation onto a first conversion region of the device, while a second light source with semiconductors emits a second light radiation into a second conversion region of the device. The second source, different from the first source and whose luminance level is typically less high, is provided with light-emitting units of submillimetric dimensions. The beams produced by the device respectively in the first region and in the second region have different characteristics and complement one another to produce one or more lighting functions.

    Abstract: The light module for motor vehicle offers a light source associated with a first part of an imaging system so as to produce a reflected beam coincident with the reflection surface of a high definition pixellated spatial light modulator, which makes it possible to avoid unnecessarily lighting the periphery of the spatial light modulator. The light source consists essentially in one or more light emitting diodes and/or has a punctiform or virtually punctiform appearance. The reflected radiation arrives on a second part of the imaging system, this part characteristically consisting in an optical projection system, some of whose elements can form a back focussing system. The module remains compact and is clearly suitable for providing adaptive lighting in a homogeneous, efficient manner and with high resolution.
