Annual inventory of Zhixing: the most dazzling lights at night on 20 19

Since human beings have learned the skill of drilling wood for fire, they no longer have to wait for the arrival of "light" between day and night. After entering the civilized era, our ability to play "light" has also become varied: the old mage who plays with the camera pops up a phrase "photography is the art of using light" from time to time to show his seniors; In the e-sports circle, various RGB lighting devices are also used to interpret the personality of DIY players.

However, when it comes to design creativity and technological content, car headlights is definitely the protagonist. Although everything will come naturally in the end, it's useless to drive without headlights to illuminate the road ahead, right? As the beginning of the annual inventory of Zhixing, Zhixingjun will talk to you about the most memorable lamps in 20 19 years.

Lexus -Bladescantm? Adaptive control system of AHS high-speed rotating mirror high beam

Design: ★★★★

Technology: ★★★★★★

Eye-catching degree: ★★

Reason for selection: It is also an adaptive high beam system, and Lexus does not take the usual path. Because they think that the adaptive high beam system built by nine LED light groups is enough to undertake the task of road lighting. But on this basis, if we want to divide the fine lighting area, at least 300-400 LED lamp groups should be stuffed into the lamp cavity. The problem is limited by the space and cost of the lamp cavity, so this method is obviously unrealistic.

So, Lexus teamed up with KOITO (Koito), a Japanese lighting factory, to build this BladeScanTM? With 12 LED light groups, the lighting division accurate to 0. 1 can be realized? Adaptive control system of AHS high-speed rotating mirror high beam.

Its working principle is shown in Figure GIF. Through the afterimage effect of human eyes, two high-speed rotating mirror reflectors evenly disperse the light emitted by LED in front. When the camera detects an oncoming vehicle or a vehicle in front, the system will instantly turn off and on the LED in the corresponding area at a speed of 0.00005 seconds to avoid dazzling glare to other vehicles. Compared with the traditional matrix LED headlights that are turned on and off in different areas, the adaptive control system of rotating mirror high beam has another advantage: it will be smoother and faster when switching lighting areas.

Zhi Xingjun's comments: On the basis of the existing matrix LED headlights, Lexus just wants to make it more perfect. This pursuit of the ultimate attitude and spirit, in fact, and 15 champagne glass LS400 engine cover, now LS? The 500-hour light knife is the same as the crane feather folding cloth, so it is difficult for people not to plant grass.

Wey- Intelligent Pixel Headlights

Design: ★★★★

Technology: ★★★★★★★

Eye-catching degree: ★★★☆.

Reason for selection: In fact, WEY's reserve in lighting technology is comparable to that of many first-line international automobile brands, such as matrix LED headlights and even laser headlights, which are all equipped on VV7, and they are all from Mande Optoelectronics, a subsidiary of the Great Wall. It is an authentic domestic product.

The smart pixel headlights selected this time still use LED as the main light source, but the DLP (Digital Light Processing) technology based on DMD chip makes the pixel headlights have the effect of a mini projector, projecting zebra crossing, speed limit warning, turn signal, car width warning and other information on the ground.

Smart pixel headlights have more than 1 10,000 addressable lighting pixels, and also support custom projection content. I just don't know if I can project WeChat expressions on the ground.

Zhi Xingjun's comments: Whether you agree with WEY brand as the leader of domestic luxury SUV, at least in terms of headlight technology, it is worthy of the saying that "domestic products should stand on their own feet and WEY should lead".

Audi-Digital Matrix LED Headlights

Design: ★★★★★☆.

Technology: ★★★★★★★

Eye-catching degree: ★★★★★

Reason for selection: Coincidentally, regarding the advanced version of matrix LED headlights, the technical direction chosen by Audi is somewhat similar to WEY. 20 19 meet our E-tron at the los Angeles auto show? Sportback is equipped with this digital matrix LED headlight with mass production conditions.

Its core lies in the DMD chip from TI (Texas Instruments), which contains as many as 6.5438+0.2 million microlenses. Under the action of electrostatic field, the microlens can be tilted at most 5000 times per second, thus projecting as many as 65438+200,000 single pixel spots. When the left and right headlights add up to 2.4 million display pixels, the higher the pixels, the clearer the display effect. I don't think I need to explain.

Therefore, there are quite a lot of tricks that this headlight can play. You can feel it through GIF. Moreover, although the current digital matrix LED headlights can only project white light and shadows, Audi has begun to develop color pixels for the next generation of digital matrix LED technology. It seems just around the corner to see the scene of a small movie through the picture projected by headlights.

Zhi Xingjun's comments: Any article about automobile lighting would be incomplete without Audi, the "lighting factory".

Mercedes-Benz-Holographic Lens Headlights

Design: ★★★★★★★

Technology: ★★★★★☆.

Eye-catching degree: ★★★★★

Reason for selection: The appearance and popularity of LED make the shape of headlights more and more diversified, but the basic components such as lens, light source and reflective bowl are inseparable from the interior of the lamp cavity. Even the headlights with rich functions can never jump out of the category of lighting tools and rise to the level of design aesthetics.

However, on EQS, there are two groups of holographic lens modules in the headlights on the left and right sides, and their rotation speed is as high as 2000 rpm. Through high-speed rotation, a three-dimensional static image will be formed in human perception. Theoretically, if Mercedes is willing, the holographic lens can display any image we imagine. As the saying goes, staring at the headlights of EQS, you will see infinite possibilities. Unfortunately, Zhi Xingjun can't learn more about the technical details of holographic headlights for the time being, so he can only wait for Mercedes-Benz to reveal it for us step by step.

Zhi Xingjun's comments: The first car equipped with headlights was not from Mercedes-Benz, but the world's first production car with LED light source is the S-class that is still on sale today. From geometric multi-beam LED to holographic lens headlights on EQS, Mercedes-Benz is a luxury brand that can compete with Audi in lighting art.

Chinese Express-Programmable Intelligent Interactive Projection Headlight

Design: ★★★★★

Technology: ★★★★☆.

Eye-catching degree: ★★★★★

Reason for selection: Many new car-making forces boast that their products are smart cars and are proud of the OTA of the whole vehicle. However, as a new luxury intelligent pure electric brand, China Mobile seems to have a deeper understanding of smart cars, especially on the first production car. On 1, they put headlamps into the smart range.

This kind of programmable intelligent interactive headlight not only has the functions of conventional partition lighting and curve lighting, but also can project the real-time speed, zebra crossing and light rail of the road ahead. At first glance, it is not much different from WEY and Audi's headlight technology.

But the most special feature of programmable intelligent interactive headlight is that it is equipped with ISD intelligent interactive display system, which can customize the projected content. Moreover, it also supports OTA upgrade, and the software can be updated at any time to obtain richer lighting effects, which is much more powerful than those headlights that are not possible to upgrade.

Zhi Xingjun Comments: Although Gaohe HiPhi? 1 The prototype was shown to us in July last year, but it is still some time before the actual delivery. I hope this headlight can meet us as scheduled, instead of staying on the PPT page.

Mercedes-Benz 64-color ambient light

Design: ★★★★★☆.

Technology: ★

Eye-catching degree: ★★★★★

Reason for selection: In addition to headlights, ambient lights are actually an unforgettable one. Moreover, the ambient light is not the exclusive configuration of luxury cars, and even the self-owned brand cars with more than 65,438+10,000 yuan are equipped with 64-color ambient lights. But it can combine the lighting with the center console so skillfully, and has a variety of theme styles, and even supports the atmosphere lights with different colors in different regions. In my impression, Mercedes-Benz did the best.

Moreover, this set of atmosphere lights is not only installed on CLS, but also on the more intimate 2020 domestic A-class and GLB, which is one of the few conscience works of Mercedes-Benz in recent years.

Zhi Xingjun's comments: No one in Zhi Xingjun's mind is the most coquettish atmosphere lamp, and he does not accept refutation.

Zhixing has something to say.

From halogen, xenon to LED, the development speed of car headlights in recent years far exceeds our phenomenon. In particular, LED headlights have been popularized to family cars below 654.38+ 10,000 yuan. I believe that the "candlelight" era, which is often vomited by netizens, will soon become a thing of the past. However, while enjoying more gorgeous lighting effects, don't forget that headlights with complex functions are still expensive. Therefore, Zhi Xingjun reminds everyone that you must be careful when driving, and you should buy it at all costs, otherwise the wallet will bleed heavily after the headlights are damaged.
