Abstract: A semiconductor light source includes at least one substrate and a plurality of submillimetre-sized light-emitting rods that extend from a first face of the substrate. The light-emitting rods are arranged in a plurality of groups the selective activation of which allows a plurality of light beams to be produced. At least two groups of rods are electrically connected to one another by an irreversibly modifiable conductive bridge such that the irreversible modification of this conductive bridge irreversibly modifies the electrical dependence of the two groups on one another.

Abstract: The invention relates to a vehicle assembly including a radar sensor configured to emit radar waves over a range of wavelengths, a luminous module. The luminous module including a sub-layer and a layer of patterns forming a sub-wavelength structured dielectric element with a repetition period of the patterns that is less than a quarter of a wavelength of the range, with the total thickness of the luminous module is equal to m times a wavelength of the range, the whole being divided by twice the equivalent refractive index of the sub-layer and of the layer of patterns, times the cosine of a refracted angle corresponding to an angle of incidence of the radar waves, where m is an integer.

Abstract: The present invention relates to a lighting system for a motor vehicle. The lighting system comprises at least one first light emitting device mounted on a front right side of the vehicle and adapted to project in front of the vehicle a first pixelated light beam. The lighting system further comprises at least one second light emitting device mounted on a front left side of the vehicle and adapted to project in front of the vehicle a second pixelated light beam. One of the first pixelated light beam and second pixelated light beam, called high resolution beam, has a number of pixels greater than or equal to at least five times, in particular greater than or equal to at least ten times, the number of pixels of the other of said pixelated light beams, called low resolution beam.
