A new laser-assisted LED headlight system for autonomous vehicles uses a durable Ce: YAG-based single crystal phosphor (SCP) that performs better at high temperatures than traditional materials.
This advanced system offers high luminous intensity that meets regulatory standards, improving visibility and brightness for adaptive driving beams (ADB).
The implementation of this technology enhances the field of view by 20% and extends illumination distance to 200 meters, making it a promising option for next-generation ADB headlights.

- Stark Tsai's research is focused on advancing lighting technologies for autonomous vehicles, specifically through the development of a novel laser-assisted LED system for adaptive-driving-beam headlights.
- The study introduces a Ce: YAG-based single crystal phosphor (SCP) that demonstrates superior thermal stability compared to traditional phosphor materials, enhancing the reliability of automotive lighting.
- Results from thermal aging tests indicate that the SCP shows less deterioration over time, ensuring consistent performance of the adaptive-driving-beam headlights, with measured high-beam intensity levels reaching up to 88,436 cd.
