1. Matrix LED headlights
It is composed of multiple LED lights. A single LED light-emitting element can be turned on, dimmed and turned off independently. If the number is sufficient, the matrix LED light group can even combine millions of light combinations, which is a large number of ordinary LEDs. Deng couldn't imagine it. For example, the Audi A8 can avoid the lights of oncoming vehicles by detecting the light of matrix LED headlights, and can sway three times to warn pedestrians, etc. Compared with ordinary LED headlights, the advantage of matrix LED headlights is that they can make a variety of lighting changes according to the environment. The disadvantage is that the manufacturing cost is high, which can be said to be relatively high.
2. Laser headlights
Unlike LED light sources, the light source of laser headlights is laser diodes, which can maintain better non-divergence than LED headlights. For example, if the light of an LED is compared to a flashlight, then the light of a laser headlight is similar to a laser pointer. The advantages of laser headlights are that compared to LED headlights, they have higher illumination brightness, longer irradiation distance, smaller size, 30% lower energy consumption, and longer service life. Matrix LED headlights and laser headlights are lighting products with high technological content. They can save vehicle power while increasing illumination, which can greatly improve the driver's active safety while driving. The disadvantage is that the manufacturing cost is high.
