About XtremeLUX

Founded in 2011, XtremeLUX is based on the decades of experience of each of its founders and other principals and their extensive networks of trusted partners. Headquartered in California’s Silicon Valley, the company conducts its research, development, and design in the U.S. and achieves its low-cost manufacturing through multiple suppliers in Taiwan who have earned our trust over many years.

Co-founder and CEO Chiamin Cheng has more than 25 years of experience with fast-paced, highly dynamic companies in the wireless communications and computer industries. Prior to co-founding XtremeLUX, he was Sr. Director of Testing and Field Engineering at NextNav, a start-up focused on developing a wide-area 3D positioning system with high accuracy in indoor and urban environments.

Before joining NextNav, he was the Senior Staff Engineering Manager responsible for global deployment and technical sales/support of AGPS technology at SnapTrack, a start-up acquired by Qualcomm in 2000. He successfully led the commercial launch of AGPS technology for mobile operators in Japan, Korea, and China. He previously held positions in product development, product validation/certification, and management at Philips Consumer Communications, IBM, and Compaq Computer.

He has extensive international experience in Asia, South America, and Europe and is bilingual in English and Mandarin. Mr. Cheng earned a BS in Physics and an MS degree in Electrical Engineering from the University of Houston and a certificate in Advanced Project Management from Stanford University.

Co-founder and CTO Dr. Edward Stoneham’s lifelong interest in physics and its application to practical needs was evident when he built his first high-voltage Tesla coil at the age of 9. He made his first LEDs as a doctoral student of Prof. James Gibbons at Stanford in 1973, with one of his creations, a dazzling Stanford “S” going up in Skylab with astronaut Prof. Owen Garriott.

During 13 years at Hewlett Packard and 24 years in three Silicon Valley startups, Dr. Stoneham applied his physics background to compound semiconductor device physics and processing, electromagnetics, electronic packaging technology, heat sinking and thermal expansion management, low-cost manufacturing technology, and power control systems in applications ranging from defense and aerospace to high-quality commercial products.

Foreseeing the potential of LEDs for general lighting, Dr. Stoneham began avidly designing LED lighting systems in 2006, turning this into a full-time business endeavor in 2009 and co-founding XtremeLUX in 2011. Dr. Stoneham is a member of Phi Beta Kappa and Sigma Xi and a Senior Member of IEEE and is an author of 22 U. S. patents plus 3 patents pending. He has an A. B. degree in Physics from U.C. Berkeley and a Ph.D. in Applied Physics from Stanford University.

COO Dr. Chinwang Tu has been involved in LED and laser chip, epi, and LED lighting application product development and manufacturing since 1984. He started as an R&D Engineer in the Optoelectronics Division of Hewlett Packard in 1984 and was the Epi Engineering Manager from 1988 to 1999. In 1999 he co-founded LuxNet, an optical fiber communication active component company, and became the President and Operations Director in 2000 until the company headquarters relocated to Taiwan in 2003. He joined Leotek Electronics Corp in 2003 and was responsible for their traffic and outdoor and commercial LED lighting products R&D until 2011.

Dr. Tu obtained his Ph.D. degree in Physics in a solid-state electronics program at Colorado State University in 1984. He has co-authored numerous technical publications in opto materials and devices journals and Solid State Lighting international conferences. Dr. Tu is an author of 12 LED and lighting-related patents and 10 pending applications.

Advisor Dr. Chen Wu has been developing technical and market solutions for LED-based applications since 1973. As Founder and CEO of Leotek Electronics Corporation, he has been responsible for identifying and developing emerging LED applications and markets for the company. He founded Leotek in 1993 and led his team through the design and development of many innovative and successful products. Leotek has now become the second-largest LED traffic signal company in the world. Prior to founding Leotek, Chen Wu was Vice President of Advanced Technology (Taiwan) Corporation and Executive Vice President of Compound Semiconductors, Inc., in California. He began his career at Hewlett Packard’s Optoelectronics Division in various roles including New LED Material Development Engineer, Project Leader, and Project Manager.

Dr. Wu obtained his Ph.D. degree in Electronic Materials from Stanford University, his M.S. degree in Physics from New Mexico Tech, and his B.S. degree in Electrical Engineering from National Taiwan University. Dr. Wu is a member of IESNA (Illuminating Engineering Society, North America), IMSA (International Municipal Signal Association), and ITE (Institute of Transportation Engineers). He has authored numerous technical publications in the area of optoelectronics and holds 26 patents related to LED applications.
