The whole work starts from the whole term, which is the usual routine used by many brands in publicity. In order not to let the confused consumers look at the screen full of English letters and be afraid, today's article tries not to appear more English abbreviation proper nouns.
Let's start with the headlights of ancient times.
It is a restored Mercedes-Benz 290 Cabriolet A (W18), an industrial masterpiece born in 1933. The shape and design can escape the reincarnation of the times, but the technology cannot, like this pair of large and godless incandescent lamps.
Prior to this, human beings have also experienced the era of kerosene lamps and acetylene lamps, and the purpose of each iteration is clear: more stable, brighter, and more durable. The above appeals, in the early days, were for driving safety considerations, and in the era of vigorous development of the post-war economic recovery industry, the design and lighting functions of the lights should also be taken into account in the overall design.
Therefore, the name of the lamp factory is not only to describe the functionality of the headlights, but also a comprehensive evaluation of the overall performance, shape, and technical application. The new era demands that the "can light up" enough factions also have to join the lamp war.
When the concept of consumer headlight technology is still stuck in the functional technology applications of "halogen/LED/laser", "adaptive far and near light, follow-up", the major depots have pressed the heads of suppliers and thrown out the terms "ADB, IFS, DLP, DMD..." tons and tons.
Saying that the lamp is the eye of the car is actually in line with the law of development: first ensure that you can see, and then consider how to make yourself look better, but in the new era, these eyes must be able to interact, to look like a torch, to look forward to brilliance, in short, to be able to convey feelings.
Back to Zhiji's DLP technology, which is a digital projection lighting technology. The technology debuted at TI Texas Instruments 2018 with a high-resolution DLP lamp solution at CES. The core features are mainly simplified: programmable and high resolution, and other incidental advantages are high brightness, quick image refresh, light source compatibility, etc.
If you can't appreciate how many application possibilities these core advantages can bring, please make up the following two things yourself:
The new iMac is only a hundred million points more programmable, high resolution, high refresh rate, digital signal compatibility and other advantages than the ancient TV.
The main components of the DLP mechanism are: light source, color management system, heat dissipation system, lighting and projection elements. The light source is filtered through the color, and after cropping, it is illuminated to the DMD chip, which is a semiconductor optical switch containing millions of reflective mirrors, which accepts and processes digital signals (0/1 in the figure below), and realizes the image of millions of pixels through the millions of mirror inverted projections.
What's more, the above processes are highly integrated and support programming. The combination of the two provides a technical basis for the interaction of car people and the interaction of cars and cars.
Of course, to really show up, Zhiji chose to stack the configuration with TI Texas Instruments and headlight assembly supplier Huayu Vision, using higher specifications of hardware and control chips, and willingly paid for the next generation of smart headlamps and lamp language functions.
Compared to the 1 million pixel level that TI just launched when DLP was launched, the DLP pixel level of the Zhiji L7 is as high as 2.6 million pixels, and it is equipped with a separate Linux operating system and a chip provided by TI.
Then ISC can appear at this time, the official name intelligent interactive taillights, in fact, the headlights of the DLP technology supplement, ISC technology can do the front and rear vehicles, pedestrians and other traffic participants of the information display, such as DLP in the prompt pedestrians to give priority to the front of the car, the tail display area can be "pedestrians through please avoid" on the public screen.
A total of 5,000 LED display light groups before and after the control is TI's latest automotive-grade 48-channel LED driver TLC6C5748-Q1, which is also one of the most expensive products at present, with a standard purchase price of 300 US dollars and is still out of stock all year round.
Finally, let's think about what lighting can bring to smart cars in this era and even the next era after the DLP and ISC technologies are enabled.
From the function definition scene to the scene definition function, that is to say, the manufacturer only provides a lighting basic hardware that can be programmed and OTA upgrade when the car is produced, with the development of automatic driving and vehicle-road coordination, each traffic participant has new interaction needs, and the vehicle can adjust its positioning at any time to match its own role.
At present, light is the most suitable medium in the triangular relationship between people, cars and roads.
But in the end, there is still a very practical concern, from the beginning of the intelligent proposal, the regulations are almost always running with technology. TI's DLP solution is also in 2018, and the world is on the same starting line in terms of related technology applications.
Too aggressive will become a disturbance affecting road safety; too conservative will become a beautiful technology bubble, and the promotion of regulations to give technology a legal identity is also an extremely important decisive factor, but fortunately, This time Chinese companies are also at the forefront.
