Description

technical field [0001] The invention belongs to the field of lighting equipment, in particular to an automobile headlamp with adjustable light beams. Background technique [0002] Automobile headlights are one of the important parts of automobiles, especially for the safety of automobiles at night. The state has made corresponding regulations on automobile headlights to ensure the safety of drivers and pedestrians. Development, it should be said that the technology has matured, since the emergence of dual-beam headlights, the contradiction between dazzling and driving lighting has been solved. However, in daily use, the inclination angle of the headlight beam will change due to various reasons, changing the correct working state of the headlight, resulting in dazzling. Commonly, the headlight beam of some cars is not adjusted properly, and some beams Upturned, when meeting cars on a flat road 150 meters away, the beam will directly hit the other driver and cause glare; some...
