The automotive headlight system is one of the most crucial parts of the automotive lighting system, capable of illuminating the road ahead during night-time or low visibility conditions, ensuring driving safety. The new intelligent headlight system includes Adaptive Front-lighting System (AFS), Adaptive Driving Beam (ADB), etc., which can flexibly control the brightness and angle of the headlights according to the actual scene to improve driving safety. Currently, the mainstream headlight systems primarily uses LED lighting, and generally composed of MCU, LED driver, power management ICs, stepper motor driver, etc.
