Publication number: 20240107645Abstract: 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.Type: ApplicationFiled: December 10, 2021Publication date: March 28, 2024Applicant: VALEO VISIONInventor: Sidahmed BEDDAR
