3、 New technology
A. ADB technology
ADB technology, also known as adaptive lighting, calculates road data through a powerful ECU algorithm and can always turn on high beam to provide maximum illumination. ADB is the biggest innovation in the field of automotive lighting. When the in car camera senses oncoming vehicles or pedestrians, ADB can automatically adjust the light to dim a single LED in the headlights or move the beam downward and horizontally. Currently, vehicles equipped with ADB account for 1% of the global automotive market share, which is expected to rise to 15% by 2025.
B. DMD technology
DMD technology, also known as digital micro mirror devices, is a high-end ADB that improves resolution. It can light up and turn off one million pixels on it, recognize the contours of obstacles on the road, and even read road signs. It can be used as an upgrade to ADB technology. Currently, there are no mass-produced models available, but the WEY-X has introduced the concept of DMD at the 2018 Beijing Auto Show.
C. μ AFS technology
μ AFS technology, also known as laser scanning technology, is an innovation of ADB technology. It will be applied to car headlights in 2021, which can take ADB to a new level. The new LED chip contains 1024 individually controllable pixels, taking a big step towards intelligent, controllable, and high-resolution LEDs.
D. LCD
It does not refer to a type of light source, but the real light behind it is still LED, although there are many LED light sources in LCD headlights. Matrix LED headlights can achieve dim lighting in a certain horizontal area, but LCD technology can theoretically achieve effective shading and lighting of any shape within pixels, and the following reaction speed is also very considerable.
E. Digital headlight technology
The headlights have the function of a projector, which can project signs similar to arrows on the road in real time, communicate with nearby vehicles, and also project zebra crossings on the road to ensure pedestrians can safely cross the road. It can also remind drivers by projecting danger warnings and other signs to ensure driving safety.
4、 Trends in Car Lamp Design
A. symbolization
Headlights and taillights have become important means of brand DNA. With the emergence of OLED technology, this graphical design will appear in a more innovative and handsome form, which is an effective way to enhance brand recognition. Major OEMs are digging into the space to create articles on the graphics of taillights. These symbolic graphics not only require intelligence but also enhance brand recognition. New technology makes symbolic design more imaginative and vivid.
B. parameterization
In fact, the concept of parameterization has been proposed for a long time. With the advancement of technology, the use of parameterization is no longer a new design technique. With the emergence of OLED technology, this graphical design will appear in a more innovative and handsome form, which is an effective way to enhance the sense of technology.
C. pulling-through
With the development of OLED components, car light strips can become thinner and more diverse in shape. The application of light strips is in line with the unified standards of major manufacturers, forming a highly representative design trend. The horizontally slender light strips not only enhance the sense of technology, but also serve as a sharp tool for car design to "show width".
D. Interactive
More and more new cars like to incorporate lighting into the overall design of the front face, causing the boundary between the headlights and the grille to become blurred. This also enables the car to have interactive functions in terms of appearance.
5、 Summary
Designing car headlights can highlight the value of a vehicle, and a good headlight design can enhance its value and temperament. Vehicle headlights have also evolved from the initial incandescent lamps to the newly emerging HID LED lamps, and the trend of headlights will also develop in a diversified direction. New materials and light sources will be further developed, and the space for improvement in lamp design will continue to expand. Performance will be improved, and car performance and appearance will be of high quality.
Laser headlights and OLED, two new technologies, make the volume of the headlights smaller and increase the plasticity of the lamp shape in the limited space inside the car; The birth of new materials and new luminescent technologies has unprecedented increased the freedom of car lamp design, making the car lamp a highly attractive "artwork" from a powerful functional component. And matrix LED headlights, LCD headlights, and ADB/DMD/ μ AFS and other technologies can make the headlights more intelligent and improve the safety of driving at night.
