    Abstract: The present invention relates to a method for operating a high-resolution projection headlight for a motor vehicle. The high-resolution projection headlight has an active LED pixel matrix light source which comprises an LED matrix monolithically integrated into a semiconductor chip with a plurality of light diode-based pixels and a driver circuit for separately controlling each individual pixel within the LED matrix. A current digital image of a sequence of images is continuously rasterized by means of a graphical controller from graphical data with at least one graphical object (50) and is provided for image reproduction with the projection headlight. A value for a thermal loading of the LED pixel matrix light source is continuously determined. During the rasterizing of a current digital image, surface areas (52) of the graphical objects (50) to be projected are at least partially masked with a masking (60, 61) and modulated, provided that the value for thermal loading exceeds a limit value. The invention also relates to a corresponding projection headlight system for a motor vehicle.

    Abstract: The present disclosure includes methods and systems for creating, using, and controlling LED headlight topologies and matrices that require fewer parts, electricity, and power, while allowing for advanced features such as bend lighting. The disclosed methods and systems can enable the use of smaller electrical systems, including control systems for LED and other headlight topologies. The disclosed methods and systems can also take advantage of pixel pairing and time multiplexing, among other methods, to manage electrical flow to minimize power needed over the circuit at given times, thus reducing the amount of material needed to create the LED headlight topology and related methods and systems for creating, using, and controlling the LED headlight topology.

    Abstract: Systems, methods, and computer-readable media for configuring automotive lamp illumination control are provided. One example method includes, at a computing device, generating a graphical user interface for configuring at an automotive lamp illumination pattern. The graphical user interface includes user input elements and is displayed by way of a display device. An input command is received by way of at least one of the plurality of user input elements. The input command corresponds to the at least one of the user input elements. A message is transmitted to an automotive lamp control device by way of a communication path including a first communication port of the computing device and a second communication port of the automotive lamp control device, based on the received input command. The message is received at the automotive lamp control device, and an action is performed in response to receiving the message.
