The California Lighting Technology Center’s third annual Don Aumann Memorial Lecture in Lighting Efficiency took place May 7 at UC Davis. Dr. Shuji Nakamura  discussed his work in the early years of LEDs' evolution, researching and developing the process for producing blue and green LEDs then the bright white LED, as well as laser diodes. He also described his more recent breakthrough in developing LEDs with gallium nitride substrates (GaN on GaN), a departure from the more prevalent process of growing GaN crystals on a sapphire or silicon carbide substrate. He illustrated the advantages of this new approach in terms of lighting efficacy, lumen output and color rendering, and he discussed the implications for next-generation LED lamps. As co-founder of lighting manufacturer Soraa, Dr. Nakamura has recently helped bring GaN on GaN technology to market.

The Don Aumann Memorial Lecture in Lighting Efficiency reflects the shared mission of UC Davis and the California Lighting Technology Center to promote energy efficiency and achieve sustainability through education.

Dr. Shuji Nakamura has been a professor in the UC Santa Barbara Materials Department since 2000. He is also Research Director of UCSB's Solid State Lighting & Energy Center. Professor Nakamura has received numerous awards, most notably for his research and development of bright white LEDs and violet laser diodes. He holds more than 100 patents, has published over 400 papers, and continues to lead innovations in science and engineering.
