LED digital car lights change the way of driving communication

In recent years, car headlights have begun to undergo a revolutionary development. The use of computers to control the LED lights of the car head can not only adjust the light and irradiation area of the car headlights in response to various situations, but can even use beams to create different texts and patterns. Future car lights Technology will become a new language for driving to communicate with the outside world.

When the night falls, apart from the street lights, the lights on the street are the two headlights on the front of each vehicle.

Ayler, Safety Test Manager of the American Insurance Institute for Highway Safety: "Many people forget that headlights are actually safety devices. Unfortunately, about half of the fatalities on American roads happen at night or under low-light conditions, as long as there is a good headlight. The lamp can effectively solve it."

Although this often-forgotten device has simple functions, it just illuminates the road ahead, but for the driver to see far and clearly, automobile manufacturers have to overcome many difficulties. A hundred years ago, car lights still needed to be ignited to illuminate the road. In the mid-twentieth century, car lights were finally electrified, which brought more problems.

Henry Ford Museum curator Anderson: "People began to complain about the glare of the headlights. They thought it was too bright. Doesn't it sound like the current situation?"

In order to solve the glare problem of the headlights, the options of high beam and low beam were developed. In the case of a lot of pedestrians, it can be replaced with a low beam that is less likely to affect the line of sight. In this way, the traditional halogen bulbs have continued to illuminate countless dark streets for sixty years. Until the emergence of HID bulbs in the 1990s, the unique color temperature allowed people to perceive clearer light.

Polo, Director of the Traffic Light Research Center: "At night, the human eye uses rod cells and cone cells at the same time, but rod cells are more sensitive to light with a blue spectrum, so blue light is more conducive to peripheral vision perception. Although there is not much difference in visibility in the center of the road, it still looks brighter.”

This kind of cold light is relatively dazzling, especially the popular SUV models in recent years. Because the body is relatively high, the height of the headlights is also increased, which causes a lot of trouble for pedestrians and vehicles.

Polo, Director of the Traffic Light Research Center: "The traffic department has received more than 5,000 complaints about the glare of headlights."

This kind of car lights was quickly replaced by environmentally friendly LED lights with clearer light directivity. The LED lights can also be combined with a computer to form an "adaptive high beam system" that can automatically adjust to reduce the glare caused by oncoming vehicles.

Morgan, the development director of the car light industry: "I can clearly see the roadside situation and the other side of the road, but at the same time, the cars that are approaching will think that I am turning on the low beam because I can turn off the light. The lights around you, if you find more than one car around, you can switch these independent lights on and off.”

In the most dangerous corners where lighting is needed the most, the "adaptive high beam system" can also follow the rotation of the wheels or adjust the sensors around the vehicle. This is just the basic operation. Audi, nicknamed the lamp factory, launched the digital matrix LED headlight technology last year. The car lights not only illuminate a beam of light in front, but also create dynamic light and shadow.

Audi Lighting Design Director Montada: "We used to design lights with only one bulb, so it was very simple, but now with LED lights, we see the possibility of using light to create everything."

The new digital headlights can lay a light carpet in front of the car. Before changing lanes, the light carpet will follow the change as an indication. The light is also used to indicate the size of the vehicle, which is convenient for driving on narrow roads. LED brings more possibilities to headlights, making headlights more than just lighting.

Audi Lighting Design Director Montada: "The future innovation is to use light to communicate, you can use light to speak, not only for driving, but also for cyclists, motorcyclists, and pedestrians (to communicate with light). This is a complicated world. We need to understand each other and we must talk to each other. I think lighting is a language for our future."
