When it comes to the application of laser technology in automobiles, you may be familiar with laser pointer welding, laser cutting, and laser marking. Thanks to the promotion of automobile manufacturers, even ordinary consumers know the laser welding of a certain car body. How many meters has the length reached.
Indeed, the application of laser processing technology as an advanced manufacturing technology in automobiles has greatly improved the manufacturing level of automobiles, and improved production efficiency and production quality. However, with the development of technology, the application of lasers in automobiles is not limited to these processing fields. Today, let me count down the applications of laser technology in automobiles that you may not know about.
Laser headlights: smaller, brighter, and more energy-saving. As an important part of the car, car headlights not only provide lighting to ensure driving safety, but also play a decorative and beautiful role. Nowadays, with the continuous development of technology, people also hope that it can be brighter, while also being more energy-efficient and durable.
Therefore, in the more than one hundred years of the development of the automobile industry, automobile headlights have also undergone a series of technological innovations, from halogen headlights and xenon headlights to today’s LED headlights. However, when automakers are still vigorously promoting the various advantages of LED headlights, laser headlights are “halfway out” and are likely to come from behind.
It is understood that BMW and Sandia National Laboratory of the United States were the first to propose the idea of using green laser pointer technology for car headlights. They used the combination of blue, red, green and yellow light sources to create a white light source comparable to ordinary light emitters, and at the same time solved the problem of poor color rendering of the white light emitted by laser diode lasers.
In 2011, BMW took the lead in applying laser headlights to the i8 concept car. The mass production model of this car was introduced to the market in the autumn of 2014. It became the world’s first mass production model equipped with laser headlights. On the first-generation 7-series models. At the same time, Audi, which has made great achievements in the field of automotive lighting and is dubbed the “light factory” by car fans, is naturally not far behind, and has already applied its matrix laser headlight technology to R8 LMX production cars.
