Advanced driving beam employing reliable phosphor-converter layer for automotive headlight
A new scheme of advanced driving beam (ADB) module employing ultra-reliable Ce: YAG-based single crystal phosphor (SCP) for use in autonomous vehicles is demonstrated. The Ce: YAG-based SCP layers fabricated by high-temperature of 1500°C exhibits excellent thermal stability. The ADB module consists of a Nichia blue LED with silicone-based phosphor, a digit mirror device (DMD), a projection lens, and two Nichia laser diodes with a Ce: YAG-based SCP layer. The ADB pattern is measured to be 88,436 luminous intensity at 0°, 69,393 cd at ± 2.5°, and 42,942 cd at ± 5°, which are well satisfied the ECE R112 class B regulation. The proposed high-performance ADB module with ultra-reliable Ce: YAG-based SCP layer is favorable as one of the promising ADB module candidates for use in the next-generation automobile headlight applications.
