On August 30, local time, the 28th DVN International Automotive Lighting Symposium was successfully held in San Francisco on the west coast of the United States. Yu Xin, vice president of Guangfeng Technology (688007.SH), was invited to attend and delivered a keynote speech on "Laser optics in Automobile Applications (Intelligent Application of Laser in Lighting Field)" to share the specific application scheme and related cases provided by ALPD semiconductor laser light source technology for vehicle optics.

according to data, DVN is a global community focusing on automotive lighting, automotive interior decoration and automotive lidar for 15 years. it organizes three to four global activities every year, covering Europe, America and Asia. it is committed to promoting internal communication in the industry, covering in-depth topics on lighting technology. its member enterprises include more than 20 world-renowned vehicle manufacturers such as Aston Martin, Audi, Bentley, BMW, Ferrari and weilai, valeo, Faurecia, Hella, Osram, Riya, 3M and other nearly 200 first-and second-tier suppliers are the most influential industry technology exchange organizations in the world.

With the theme of "Illuminating the Future-Safety, Communication and Emotion of Electric Vehicles, Self-Driving Vehicles and Driving", this year's International Automotive Lighting Symposium brought together more than 250 automotive-related industry chain experts and corporate decision makers from around the world to focus on the industry. The latest trends conduct in-depth exchanges and jointly discuss key strategic decisions to improve products and technologies.

Under the tide of intelligent electric, the development of the automotive industry emphasizes multi-technology integration and innovation. As important technologies in the automotive field, laser display and laser lighting have received active attention from the industry.

Yu Xin believes that the advantages of laser application in the field of vehicle optics are very obvious. In the field of display, compared with the traditional vehicle display scheme, laser display has the advantages of flexible installation, easy to hide, changeable shape and size, separation of display equipment and picture, etc. In the field of lighting, the laser light source can achieve higher brightness, smaller volume and higher cost performance. For example, under the condition of using the same DLP or LCoS chip, the laser luminous flux is 4 times higher than that of LED.

As one of the inevitable trends in the development of automotive lighting technology, laser headlights have been used by many global luxury car brands. Yu Xin said that laser headlights are adapted to the trend of intelligence. In addition to basic lighting, they can better play the function of driving assistance. At the same time, they can be integrated with intelligent configurations such as lighting display, ADB, AFS, etc. to enhance driving safety and improve Effective interaction with drivers, passengers and pedestrians; from the perspective of car appearance design, ultra-compact laser headlights can not only provide high brightness, but also redefine the front face design of the car.

data show that guangfeng technology is a leading enterprise in the field of laser display technology in the world, and is also the first batch of listed enterprises on the science and technology board. the original ALPD semiconductor laser light source technology is the only laser display and lighting technology that meets the vehicle regulations at present. it has a self-certified blue laser and has the technical characteristics of high color rendering. while maintaining high brightness, it can take into account the balance between finger rendering and color rendering. At the Shanghai Auto Show held in April this year, Guangfeng Technology independently participated in the exhibition and released the world's first car-grade color laser headlights, demonstrating innovative ideas for smarter and more interesting driving experiences for future cars.

In the face of the question of why laser headlights need color display, Yu Xin believes that ALPD color laser headlights can realize human-computer information interaction inside and outside the car in a more eye-catching and vivid form, making information easier to be seen, improving the safety of driving and pedestrians, having better entertainment, and making the interaction more diverse.

In the Q & A session at the end of the seminar, the related technologies and products of Guangfeng Technology received most questions from the audience and became the focus of attention of the participants.
