Trends in styling and advanced functionality of automotive lighting drive the development of LED light sources along the three vectors of high luminance, miniaturization and function integration.  Freedom of design, often trending towards slim or low-profile automotive lighting systems, is the main driver behind miniaturization and luminance.  New functionalities, such as adaptive driving beam (ADB), and dynamic signaling, require arrays of individually controlled LEDs, which bring challenges with growing complexity to managing optical efficiency and thermal performance. ADB applications require light sources that are an integration of discrete elements to create up to ~100 pixel systems, or as a directly imageable source of 10-50k pixels that are <50um in size. New technologies are needed to enable close placement and interconnectivity, while meeting optical, luminance and thermal requirements of applications.  We discuss the innovation that enables next generation automotive lighting systems and their capabilities.
