Interview with Julian Carey, Intematix

Nov 3, 2011

At the LEDs 2011 conference and exhibition LEDs Review has received an opportunity for an exclusive interview with Julian Carey, Director of Marketing at Intematix.

Prior to joining Intematix, Julian directed product management and corporate branding for Prysm, a maker of Laser Phosphor Displays. In the lighting area, Julian was VP of Marketing at LUXIM where he launched plasma lighting products for OEMs in consumer TV, commercial display and general lighting applications. Previously, he served as product marketing manager at Philips Lumileds Lighting where he led the commercialization of their LED product family into diverse markets including cell phone camera flash, printing and imaging, signage and general lighting.

Prior to Philips, Julian held product design and process engineering roles developing the first family of power LEDs and systems at the Optoelectronics Division of Hewlett-Packard.

He holds a BS degree in mechanical engineering from Stanford University and an MBA from MIT Sloan.

Despite a busy conference schedule and a presentation to prepare for, he has found time to answer our questions.

LEDs Review: What do you consider one of the major achievements of Intematix in 2011?

Julian Carey:  I believe Intematix had major breakthroughs this year in terms of being able to reach 98CRI light quality for an LED package implementing a combination of our phosphors and the commercialization of our  ChromaLit remote phosphor solutions ( We have seen significant customer demand growth and we expect even more new products coming out next year that utilize ChromaLit.

ChromaLit is a phosphor composite layered onto the substrate and separated from the blue LED energy source. The remote phosphor emits consistent high-quality light when excited with blue light. Because the phosphor has been separated from the energy source and can now be made in any shape and any color, unidirectional light, hot spots, inconsistency and design limitations are no longer SSL challenges. One of the most important ChromaLit features is an increase in efficacy of the LED lighting system up to 30%.


LEDs Review: What are the ongoing projects in Intematix that you are excited about?

Julian Carey:  A large portion of our company’s team is dedicated to Research and Development and they keep me constantly excited about finding new ways to improve performance of our phosphor solutions.

LEDs Review: Do you offer custom projects for your customers and close collaboration with your technical team to reach objectives of the customer? Can you name a recent successful collaboration project?

Julian Carey:  Yes, absolutely, we always collaborate closely with our customers and share our technical expertise to help them solve their problems.  We have very detailed “Application notes” that describe our extensive study of compatible ad non-compatible adhesives and other materials. We also usually have a good back-and-forth communication between our technical experts and customers and offer constructive critique to them that help in designing highest quality lighting. 

One of the great recent examples is SAN-PIN Lighting Technology in China ( They have taken the task of learning how to use Intematix Phosphor solutions most seriously and had a very impressively short learning curve and very efficient training. They have prepared twelve products for the presentation at Hong Kong Lighting Show within a very aggressive timeline and have been able to reach outstanding quality.

Overall there are fourteen customers presenting at Hong Kong Lighting Show that use ChromaLit in their LED luminaires.

LEDs Review: How would you describe your experience on the Asian market?

Julian Carey:   We have a very positive experience doing business in Asia. About two thirds of our business is actually based in Asia. A lot of our phosphor is manufactured in China, although ChromaLit is made in USA.

LEDs Review: What other markets do you target?

Julian Carey:   In addition to the North American and Asian markets, we are currently in the early stage discussions with customers from South America (Brazil). We also work closely with European countries, in particular Germany, Italy and Spain. We had some early discussions with Russian companies. Intematix is growing fast in order to keep up with the demand for our products in different parts of the world.

LEDs Review:  The cost of the LED lighting solutions is expected to be getting more and more competitive, how does Intematix prepare for lowering the cost of your phosphor solutions?

Julian Carey:   We work hard on developing and optimizing our technology and that should allow us to reach the cost goals. Overall we have been able to become material and component supplier of choice for the best quality of light in LED lighting and we hope to keep it this way.
