  • METHOD FOR CONTROLLING A PIXELATED LIGHT SOURCE
    Publication number: 20240107645
    Abstract: The invention relates to a method for controlling a pixelated light source for a motor vehicle. The method makes it possible to prevent thermal runaway and premature ageing of the elementary pixels of the source independently of the projected light levels. By dynamically adapting the electric current intensities at the elementary light sources, the control method provides protection for the semiconductor junctions of the pixels of the pixelated light source in order to increase their lifespan and avoid visible defects in a beam projected onto the road due to thermal runaway or premature ageing of the semiconductor junctions.

  • Beam steering devices
    Patent number: 11940711
    Abstract: A beam steering device includes a substrate with a first refractive index that defines a cavity, an electroactive material in the cavity that has a variable refractive index, and two sets of opposing overlays. The overlays in one set of opposing overlays are parallel to each other, while the overlays in the other set are tilted with respect to each other. This allows one or more electric fields between the overlays to be used to align the electroactive material in two different directions to change its refractive index, allowing for a faster speed of beam steering through refraction than conventional approaches.
