Therefore, the cost requirements are becoming more and more stringent, especially for multi-row or high-pixel lamps, cost is a major factor restricting its application.

[0003] At present, the traditional ADB high beam optical system solution is a silicone inner lampshade + lens. The headlight module assembly structure under this optical system is relatively complex, large in size, and high in cost.

[0004] In view of this, it is necessary to design an intelligent high beam lighting system to overcome the above defects. Utility Model Content
