Method for controlling pixelated light beams in vehicles
The patent US12071067B2 outlines a method for controlling lighting devices in motor vehicles, specifically focusing on lighting modules that emit pixelated light beams. The method begins with receiving an instruction to emit a desired pixelated lighting function. It involves creating a digital image for each lighting module that corresponds to a predetermined emission area. This digital image is then corrected based on the characteristics of the light sources and optical devices within the modules. Finally, the corrected digital image is used to emit a pixelated light beam from each module.
Further claims detail the processes involved in creating and correcting the digital images. This includes selecting photometric images or layers stored in memory to form a base image, applying various masks, and utilizing anti-dazzle and attenuation masks to enhance the emitted light. The correction process may involve sampling the digital image according to the number of light sources, applying filters, and adjusting for the vehicle's orientation or road slope. Additionally, the patent encompasses a computer program and data medium designed to implement these methods, ensuring that the lighting functions can be effectively controlled and adjusted in real-time based on the vehicle's conditions and requirements.
