We all know that car headlights are composed of light sources such as high beams, low beams, turn signals, and width lights. Nowadays, more and more cars have used LED light sources, and now more and more cars have begun to use matrix LED headlights. Many people do not understand it very well. So what is the difference between matrix LED headlights and ordinary LED headlights? Today we will talk about it in detail.

First of all, the number is different. Matrix LED headlights are not a single light source. They are characterized by modularizing the light source. Matrix LED headlights usually contain dozens or even hundreds of light-emitting units. These light-emitting units can be LEDs can also be laser diodes, and each light-emitting unit can be independently controlled. Ordinary Led headlights are composed of a single or several light-emitting units, which can only be turned on or off as a whole.

Secondly, the flashing method is different. Ordinary led headlights can only be turned on and off. It is turned on and off in groups, so he can only display a flashing like ordinary turn signals. For the matrix LED headlights, each lamp bead can be turned on and off independently, and then the brightness of the light can be adjusted.

Matrix LED headlights cooperate with powerful sensors on the vehicle. The matrix headlights can automatically identify road conditions to provide the most suitable lighting brightness and angle. When following or meeting vehicles, it will also turn off the light-emitting units that affect the other vehicle and other light sources. Normal opening, automatic closing and automatic light adjustment, some matrix LED headlights can also adjust the light of the car according to the angle of the driver's steering wheel, weather conditions, and driving speed, which is very intelligent.

In addition, there are some advanced digital matrix LED headlights, as well as a more intelligent projection image function, which is impossible for ordinary LED headlights. For example, a certain digital matrix LED headlight of Audi can make mosaics on the wall. If you think that's all, then you're probably underestimating Audi's lighting technology. Audi's digital matrix LED headlights are composed of more than 1.3 million tiny reflectors, it is like a projector, it can even play a movie on the wall, it can play light, and the carpet changes lanes with the vehicle's left and right. Moving left and right, it can even make light zebra crossings for pedestrians to walk on. If the automotive industry says Audi lighting is the second, I believe no one dares to say it is the first.
