On December 4-5, 2024, the 33rd DVN (Shanghai) International Automotive Lighting Symposium concluded successfully, with the forum theme focused on “Automotive Intelligent Interactive Lighting Technology.” Guangdong APT Electronics Co., Ltd. (stock code: 2551.HK) had its Automotive Division Operations Director, Wan Chui-Ming, deliver a report titled “Innovation and Application of High-Power LEDs in Automotive Lighting.” The report concentrated on high-power LED technology and its extensive applications in automotive lighting, particularly the innovations and progress in high-power LEDs and Adaptive Driving Beam (ADB) systems.
Key Topics Covered in the Report
The report covered key technologies in high-power LED chips and packaging, a high-power ceramic LED product portfolio, the introduction of integrated adaptive high beam LEDs, and a comprehensive summary. The content was both technically rich and detailed, attracting significant attention from industry experts and technology enthusiasts.

Wan Chui-Ming explained that high-power LEDs, with their exceptional energy efficiency and powerful light output, have gradually become one of the core technologies in the automotive lighting sector. A crucial aspect of high-power LEDs is the design of optical and thermal management systems, which are key factors in ensuring stable operation in harsh automotive environments. Flip-chip technology, an advanced packaging method, provides significant technical advantages.
APT Electronics‘ Innovation and Manufacturing Capabilities
With a solid foundation in flip-chip LED chips, LED packaging, and module technology, APT Electronics has successfully built a rich production capacity for LED devices and application products, meeting the demands of smart automotive lighting, new display devices, and high-end lighting applications.
As the demands for lighting systems in automobiles continue to rise, high-power ceramic LED products have become an essential component in many automotive lighting solutions. APT Electronics‘ automotive-grade ceramic LED products offer not only high power and brightness but also excellent performance in heat management, stability, and reliability. Among these products, the 1519 SLES 5W and 1*3 chips 9W are widely used in automotive headlights, daytime running lights, and special indicator lights. These high-power ceramic LED products from APT Electronics effectively reduce energy consumption while improving overall system performance.

ADB Technology in Automotive Lighting
In the area of Adaptive Driving Beam (ADB), APT Electronics has developed a new generation of 100-pixel and 32-pixel LED matrix intelligent automotive lighting modules, which are already mass-produced and available on the market.
These modules, based on APT Electronics‘ automotive-grade light source devices and integrated drive systems, provide exceptional contrast and compact luminous surfaces. Supported by mature optical technologies, these products meet the strict requirements of ADB regulations for headlight functions.

Future Trends in Automotive Lighting
As technology advances, automotive lighting systems will continue to evolve with more innovative solutions. In the future, as LED light source efficiency improves and intelligent control systems continue to develop, LED technology will play an even more significant role in automotive lighting. This will drive the industry toward smarter and more efficient solutions, offering drivers a safer and more comfortable driving experience.
