The four major "headlight" black technologies are more stylish than each other. Are domestic brands going to surpass Audi?

With the rise of domestic new energy vehicles, a variety of new technologies have been gradually applied. Among them, the new technology of headlights can be said to be the most obvious one that many consumers can perceive.

Nowadays, all kinds of headlights are installed on new energy vehicles. What's more, fancy headlight technology has become an important selling point for many mid-to-high-end new energy vehicles. Even Audi, known as the "lighting factory", has lost its bragging rights in front of today's domestic new energy vehicles.

Why is the headlight technology of new energy vehicles advancing so rapidly?

More than ten years ago, when the Chinese automobile market was still in its early stages of rapid development, foreign brands were constantly pouring into China, while domestic brands at the time were still struggling in the relatively low-end market, so the competition in technology was not very fierce at the time.

Even five or six years ago, when new energy vehicles had not yet fully emerged, many low-end models priced below 100,000 yuan were still using the technologically backward but cheap halogen lamp + lens combination. Xenon headlights were still an important configuration for high-end models, and the LED headlights that are now popular are still in a popularization period before large-scale diffusion.

This is obviously closely related to the technical level of the car headlights themselves, but behind this, there is a very important related factor, that is, the car's power consumption.

At that time, fuel vehicles still occupied a dominant position, and the on-board electrical appliances of these fuel vehicles were basically driven by the electricity generated by the generator driven by the car engine. Therefore, the car's power supply capacity was very limited, and could basically only meet the power needs of various on-board controllers and basic electrical equipment such as car computers, interior lighting, etc.

Nowadays, the matrix headlights, smart headlights and other technologies that are popular in electric vehicles have a huge load on the power of the whole vehicle in the environment at that time. But now with the power batteries of new energy vehicles, the supply capacity of on-board power is completely different. The abundant power provides a very good foundation for the technical progress of headlights.

In addition, the further improvement of the intelligence level of new energy vehicles has also benefited headlight technology. For example, various radars on the body provide powerful perception and decision-making capabilities for the intelligent control of headlights, and smart headlights can have richer application scenarios.

In addition, the maturity of LED headlight technology has also improved the luminous efficiency of the headlight group, reduced energy consumption, and extended life, providing good conditions for the headlight to achieve more functions. Engineers have derived matrix LED light groups based on LED headlights, which achieve a variety of lighting effects through precise calculations by sensors and on-board computers.

What kind of black technology is there in today's car lights?

With the support of high energy supply and high computing power of new energy vehicles, the adaptability of headlights to automotive lighting scenarios has been further improved, and they are no longer simply used for vehicle lighting, but have opened up more ways to achieve vehicle use scenarios. The following are all very common new technologies in today's new energy vehicles, or are rapidly becoming popular.

1. Entry level: automatic headlights

Its principle is very simple, that is, to detect the ambient light through light sensors such as photoresistors, and compare it with the set light intensity, and the vehicle controller decides whether to turn on the headlights, which greatly simplifies the driver's operation and allows the driver to focus on smooth driving. With the continuous reduction of the cost of car lights and the continuous improvement of reliability and life, automatic headlights have become more and more popular. Now all models below 100,000 yuan can use automatic headlights.

2. Advanced: Adaptive high and low beam

Its function is to automatically switch between high beam and low beam according to the current speed of the vehicle and the road conditions ahead, so as to avoid the driver of the oncoming vehicle losing his vision due to the glare of the high beam when meeting, thus causing an accident. Its principle is to use the camera of the driving assistance system to identify obstacles such as other vehicles and pedestrians in front of the vehicle, so as to determine whether the light source needs to be switched. Therefore, the vehicle needs to have visual recognition driving assistance capabilities. Therefore, this configuration is basically installed on models with L2-level driving assistance configuration.

3. High-end: Adaptive lighting headlights

It is a more powerful technology than adaptive high and low beam, which not only requires the support of driving assistance capabilities, but also requires the vehicle to have multi-pixel LED matrix headlights. It can change the shape of the light according to driving information such as weather conditions, external light, road conditions, etc., such as achieving the same-side offset of the illuminated area when turning; or changing the light shape when detecting vehicles or pedestrians ahead to avoid direct exposure to vehicles and pedestrians; or automatically extending the headlight projection distance forward on the highway; or automatically expanding the lighting range at intersections, etc.

4. Flagship: Smart interactive headlights

This is a typical technology representative of the extension of headlights from a single lighting function to providing diversified vehicle-exterior interaction capabilities. Relying on multi-pixel LED headlights and smart cockpit technology, it can realize the multi-pixel matrix LED headlights, by changing the lighting mode of the headlight matrix, turning the headlights into an exterior screen, displaying various patterns, such as children, arrows, and even user-defined hearts, text, etc., and even playing dynamic light language, or directly projecting it outside the car. It can be said that it is a concentrated display of the culmination of smart headlight technology.

summary

With the development of automobiles, headlights have also gone through the era of halogen lamps, xenon lamps, and the current LED and laser headlights. Their functions have also evolved from traditional lighting to atmosphere creation, body beautification, and even emotional interaction. With the advancement of automobile electrification and intelligence, the shape and technological content of domestic new energy headlights have been further improved. What will be the future trend?
