[0002] With the development of automotive lighting technology, ADB headlights are becoming more and more common. However, due to the limitations of headlight shape and headlight space, modules with dual functions of low beam and ADB are being used in more and more models. To ensure the uniformity of the ADB light pattern and compliance with regulations, a light shield is designed at the light entrance area of ​​the ADB inner lens to prevent light from crossing between particles and reduce stray light in the ADB light pattern.
