Automotive Black Technology Chapter 724: : A perfect experience brought about by technological innovation!
www.lnmao.org, the fastest update to the latest chapter of automotive black technology!
What kind of headlight is that?
It looks like an eye with two pupils! Although the brightness of the car lights was not adjusted to the maximum for the convenience of display, you must know that the lighting inside the wind speed laboratory is extremely bright, and Zhengxin’s wind speed laboratory, whether it is the floor or the four walls, are all pure milky.
But even under such lighting intensity, the car lights still look so bright.
If you look carefully, you will find that the shape of the light-emitting unit inside the car light is like science fiction!
What kind of look is that?
It is like a piece of pure and transparent ice, with the excess parts removed by milling, leaving only two spoon-like sections like the Big Dipper. Looking at it as a whole, it looks like two pupils that have been lined and artistically beautified!
And if you look carefully, you will find that the luminous unit is actually made of two colors!
Behind the light-emitting unit is a ghostly blue. The end of the reflective unit, which is the instant noodles in front of the car lights, exudes a warm milky white light!
What kind of white is that?
It is so white that it makes people feel like there is a kind of warm sunshine in a dream, rushing toward them.
It's so white that you can feel the sun shining on you through the thin clouds.
Baide, the reporters here and the netizens in front of the live broadcast page even mistakenly thought that they had arrived in heaven, bathed in the holy light!
Li Fanyu was very satisfied when he saw the reporters' stunned and confused eyes.
He raised the corners of his mouth slightly, dragged his hand under the "angel eyes", and said: "Automotive lighting technology has gone through three generations so far. From the initial halogen, to xenon lighting and now on the market, Popular LED light source
However, does LED represent the pinnacle of vehicle lighting technology?
Yes before today, but after today, it will be replaced by a new generation of lighting method developed by our group's R&D center - laser light source!
This lighting technology is a step forward to build on the past. It is bound to become the next step in vehicle lighting technology after LED headlights! ”
Li Fanyu stood next to the "angel eyes" for display, and spoke with pride on his face under the astonishing gazes of a group of reporters.
In the empty wind resistance laboratory, his words reverberated, which was extremely heart-wrenching.
A reporter broke free from the confusion and immediately raised his hand and asked: "Director Li! First of all, I want to say that this car light is so beautiful! I have never seen such a charming car light! But I I would like to take the liberty of asking, how does this kind of car light work? Can you explain it in detail? ”
Looking at the reporters in the front row raising their hands to ask questions, Li Fanyu nodded, "Of course! As we all know, laser diodes have also come out as early as the birth of light-emitting diodes. Although the application range of laser diodes is not as wide as that of light-emitting diodes, But it still plays a certain role in measurement, electronics, communications, processing and other fields.
Similar to the principle of LED, laser diodes can emit monochromatic laser light. White light radiation can be formed by synthesizing multiple monochromatic laser sources, or by passing laser light through transparent media such as quartz, resulting in spectrum broadening.
Based on this, the R&D team of our group converts the blue light of the laser diode into diffuse white light by filtering it through the fluorescent material that runs through the headlight unit. This has created our new generation of laser lighting technology! ”
As soon as he finished speaking, another person raised his hand and stood up and asked: "Director Li, since you said that this lighting source uses laser, will it cause harm to human eyes? You also know that xenon headlights The reason why it has been criticized by the market is that it is too bright when used in cars, which can cause light pollution to pedestrians or other vehicles and cause various accidents. ”
Ha!
If that's the case, what's the point of doing it?
Brother, this question you asked is of no standard at all!
Li Fanyu shook his finger arrogantly and said scornfully: "Of course not! After we use special phosphors to convert light, this lighting source is brighter than conventional light sources. But at the same time, it is very harmful to people. It’s also friendlier to the eyes! Do you feel any discomfort in your eyes after watching it for a long time? It’s just a bit dark when you look at other places.”
The reporter who just asked the question rubbed his eyes, looked around, and found that it was exactly what Li Fanyu said,
He smiled sheepishly 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 LED light source that is currently highly praised?"
Li Fanyu waved his hand, "Please remove the modal 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, etc.
Compared with LED headlights, laser headlights have advantages, especially in terms of size.
The length of a single laser diode component can be 10 microns with our group's existing process, which is only one percent of the size of conventional LED components! This means that our designers can reduce the size of the lights significantly if they wish. This will definitely bring revolutionary changes to the design proportions of various elements on the front face of the car!
Another significant advantage of laser headlights is in luminous efficiency. The luminous efficiency of general LED lighting can reach about 100 lumens per watt, but the laser diode components currently used by our group can reach 170 lumens per watt!
Guys, do you know what this means? ”
Li Fanyu glanced at the reporters who were intrigued, and then said quickly in a popular science tone: "When the same lighting conditions are met, the energy consumption of laser headlights is less than that of LEDs. 60% of the lights! This lighting source further reduces energy consumption and is more in line with the energy-saving and environmentally friendly trend of future automobiles!
Do you think it can be compared? ”
Wow!
I have to say that the reporters present were very professional. With just three questions, the main performance of laser headlights has been revealed from Li Fanyu!
"So, Mr. Li, will your company install headlights using this technology on all models of Zhengxin Group?"
Poof!
This time he asked about Li Fanyu's weakness, "As for this question, it is obviously not practical at this stage. Will you set diamonds on slippers?"
Seeing the reporter scratching his head in embarrassment, Li Fanyu waved his hand and said with a smile: "Just kidding. At present, we have fully mastered the laser illumination source technology, but this new technology has no specific application at this stage. At the same time, the cost is still very high.
However, I and Zhengxin product engineers are working on cost reduction.
At this stage, in order to prove Zhengxin’s R&D and design capabilities, we will implant angel eye-shaped car lights into the entire A6 series. In order to ensure the cost of the entire vehicle, the A6 flagship model, A8 and Range Rover flagship models, these three high-end models of our group, are equipped with the new lighting technology of laser headlights.
But I believe that in the near future, this technology will definitely be installed on most of the models produced by our group, allowing consumers to feel the perfect experience brought by technological innovation! ”
