What kind of headlight is that?

It looks like an eye with two pupils! Although the brightness of the headlights is not adjusted to the maximum for the sake of display, you must know that the lighting inside the wind lab is extremely bright, and the wind speed laboratory of Zhengxin, whether it is the floor or the four walls, is pure milky white.

But even at this intensity of illumination, the headlight still looks so dazzling.

If you look closely, you will find that the shape of the light-emitting unit inside the headlights is science fiction!

What kind of look is that?

It was as if it had been made of a piece of pure, transparent ice, and the excess parts had been scraped away, leaving only two spoon-like sections like the Big Dipper. Looking at it as a whole, it looks like two lines and a certain artistic beautification of the pupils!

And if you look closely, you will find that the luminous unit is actually composed of two colors!

Behind the light-emitting unit, there is a dark blue. And the end of the reflective unit, that is, the bubble noodles in front of the headlights, exude a warm milky white glow!

What kind of whiteness is that?

It is so white that it makes people feel that there is a kind of warm sunshine like a dream, rushing towards them.

It was so white that it seemed to make people feel the sunlight shining on their bodies through the thin clouds.

Bai De made the reporters and netizens in front of the live broadcast page even mistakenly think that they had come to heaven and bathed in holy light!

Seeing the reporters, a stunned and confused gaze, Li Fanyu was very satisfied.

He hooked the corners of his mouth slightly, dragged his hand under the "angel eye", and said: "Automotive lighting technology has gone through three generations so far. From the original halogen, it has developed into xenon lighting and now LED light sources that have become popular on the market.

But are LEDs the pinnacle of vehicle lighting technology?

Yes before today, but after today, it will be replaced by a new generation of lighting developed by our group's R&D center - laser light source!

This lighting technology is a step forward in the future. It is also bound to become the next step in vehicle lighting technology after LED headlights!"

Li Fanyu stood next to the "angel eyes" used for display, and said proudly under the stunning gaze of a group of reporters.

In the empty wind resistance laboratory, his voice echoed in bursts, which was extremely impressive.

A reporter got out of the confusion and immediately raised his hand and asked: "Li Dong! First of all, I want to say that this lamp is simply too beautiful! I have never seen such a charming headlight! But I would like to take the liberty of asking, how does this kind of lamp work? Can you elaborate on it?"

Seeing the reporter in the front row raise his hand to ask, Li Fanyu nodded, "Of course! As we all know, as early as the birth of light-emitting diodes, laser diodes have also been introduced. Although the application range of laser diodes is not as large as that of light-emitting diodes, it still has a certain weight in the fields of measurement, electronics, communications, and processing.

In the same way as LEDs, laser diodes can emit monochromatic lasers. White light radiation can be formed by combining multiple monochromatic laser sources, or by passing a laser light through a transparent medium such as quartz, resulting in a broadening of the spectrum.

Based on this, our R&D team converts the blue light of the laser diode into diffused white light by filtering it through the fluorescent fluorescent material that runs through the headlamp unit. This is the result of our new generation of laser illumination technology!"

As soon as his words fell, someone raised his hand, got up and asked: "Li Dong, since you said that this lighting source uses lasers, will it cause harm to human eyes? You also know that the reason why xenon headlights have been criticized by the market is because they are too bright. When used in automobiles, it can cause various accidents due to light pollution to pedestrians or other vehicles. ”

Ha!

If that's the case, what's the point of doing it?

Little brother, you don't ask this question at any level!

Li Fan shook his finger arrogantly and said contemptuously: "Of course not!" After we convert the light through a special phosphor, this lighting source is brighter than the conventional light source. But at the same time, it's also more friendly to the human eye! Do you feel any discomfort in your eyes after looking at it for a long time? After seeing the angel eye, it's just a little dark when you look elsewhere, right?"

The reporter who asked him just now rubbed his eyes, looked around, and found that it was really as Li Fanyu said.

He smiled embarrassedly and sat back in his chair.

As soon as he sat down, another reporter followed him and asked, "But can this lighting method compare to the current high-praise LED light source?"

Li Fanyu waved his hand, "Please remove the mood particle '?'! Compared with traditional LED headlights, the advantages of laser headlights are quite obvious!"

The laser headlights currently developed by our group have most of the advantages of LED headlights. For example, the response speed is fast, the brightness attenuation is low, the size is small, the energy consumption is low, the life is long, and so on.

Compared to LED headlights, laser headlights have an advantage, especially in terms of size.

The length of a single laser diode element can be 10 microns with our group's existing process, which is only one hundredth of the size of a conventional LED element! This means that the size of the lamp can be greatly reduced if our designers want to. This will definitely bring revolutionary changes to the design proportions of the various elements on the front face of the car!

Another significant advantage of laser headlights is in terms of luminous efficiency. The luminous efficiency of general LED lighting can reach about 100 lumens per watt, while the laser diode components currently applied by our group can reach 170 lumens per watt!

Guys, do you know what that means?"

Li Fan foolishly glanced at the reporters who had been hung up on their appetites, and then quickly said in a popular science tone: "When the same lighting conditions are met, the energy consumption of laser headlights is less than 60% of that of LED headlights!"

You say, can you compare?"

Wow!

I have to say that the reporters present were very professional. Just three problems have already deducted the main performance of the laser headlight from Li Fanyu's mouth!

"So Dong Li, will your company install the headlights that apply this technology to all the models of Zhengxin Group?"

Burst!

This time, it was a question about Li Fanyu's weakness, "As for this question, it is obviously unrealistic at this stage." Would you set diamonds in your slippers?"

Seeing the reporter scratching his head in embarrassment, Li Fanyu waved his hand and said with a smile: "Just kidding." At present, we believe that the laser illumination source technology has been fully mastered, but the cost of this new technology is still very high at the application level at this stage.

However, I, and the product engineers of Zhengxin are working on cost reduction.

At this stage, in order to prove the R&D and design strength of Zhengxin, we will implant the angel eye shape lamps into the entire A6 series. In order to ensure the cost of the whole vehicle, the A6 flagship model, the A8 and the Range Rover flagship version, these three high-end models of our group are equipped with laser headlights, a new lighting technology.

However, I believe that in the near future, this technology will definitely be installed on most of the models produced by our group, so that consumers can feel the perfect experience brought by technological innovation!"
