Abstract
An automotive headlight system and an adaptive automotive headlight system with instant compensation control are provided. The automotive headlight system includes a light source, a total internal reflection prism, a digital reflecting element, a freeform lens, and a multi-curve-reflector. The total internal reflection prism is used for redirecting and reflecting light beams from the light source. The digital reflecting element is controlled to switch to a plurality of states with regard to reflected light beams from the total internal reflection prism then compensation patterns will be promptly given during different states. The freeform lens is used for controlling directions of the light beams from the digital reflecting element. The multi-curve-reflector has a plurality of radii of curvature for reflecting the light beams from the freeform lens. As the automotive headlight system merely uses optical refractive and reflecting elements so that the number of components and cost is greatly reduced as compared with the prior art. Furthermore, the most important is that this invention proposes a new design and instant and personalized compensation solution to reduce more driver's risks.
