    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: An optical wireless communication system for a vehicle comprises a photonic device and control electronics configured to control the photonic device. The photonic device comprises a plurality of photonic components arranged in a two-dimensional matrix array, and the control electronics are configured to control individually or in groups the photonic components of the plurality of photonic components. Each photonic component or each group of photonic components is configured, where appropriate conjointly with an optic, so as to emit and/or receive at least one optical wireless communication signal in a propagation direction that is discriminable relatively to a propagation direction of optical wireless communication signals emitted and/or received, respectively, by at least one other photonic component or by at least one other group of photonic components of the plurality of photonic components.
