To meet the demands of safe and comfortable driving, we present a new design of a highly energy-efficient Adaptive Front-lighting System (AFS) that can automatically adjust the shape, range, and light distribution of the illumination. The AFS system consists of a lamp, a reflector, light pipes, a Digital Micromirror Device (DMD), a condenser, and a lens. Our simulations show that this system can achieve different beams, such as basic passing beams, town beams, motorway beams, and corner lighting. By using the second light pipe to collect light, the illumination efficiency is increased by 10 points, accordingly reducing the generated heat of the lighting system.
