[0002] Car headlights are car headlamps. Headlights are lighting fixtures used to identify the front view when driving at night. They are symmetrically installed on both sides of the front of the vehicle. LED is an electroluminescent device that uses solid semiconductor chips as luminescent materials and emits light directly through the recombination of carriers to cause photon emission. LED headlights are lighting fixtures made using LED as a light source.

[0003] Car headlights are the eyes of a car. They are not only related to the external image of a car owner, but also closely related to safe driving. Headlights generally refer to high beams and low beams. Their main function is to provide lighting for the driver to illuminate the road ahead of the vehicle and provide a good field of vision in bad weather or at night. The high beam has a high angle and a long lighting distance, and is usually used when the vehicle speed is higher than 30 kilometers per hour; while the low beam has a low angle and a short lighting distance, and is generally used under normal circumstances. The switching principle of high and low beams mainly depends on the role of reflectors and focus to make the light emit in a specific direction.
