BluGlass-Bridgelux JDA to evaluate RPCVD and tunnel junction technologies for cascade LEDs in general lighting market

BluGlass Ltd of Silverwater, Australia – which was spun off from the III-nitride department of Macquarie University in 2005 – has entered into a joint development agreement (JDA) with Bridgelux Inc of Fremont, CA, USA (a vertically integrated manufacturer of solid-state light sources for lighting applications) to build on BluGlass’ remote-plasma chemical vapor deposition (RPCVD) tunnel-junction technology in order to develop cascade LEDs, establish a path for mainstream applications in the growing general lighting market.

For over 15 years, Bridgelux has designed and produced LED lighting solutions for the general lighting market that are said to be high performing, energy efficient, cost effective and easy to integrate. Its focus on technology development has yielded proprietary innovations in LED design and manufacturing processes that enable its products to accelerate the mass adoption of LED lighting.

BluGlass’ unique RPCVD technology is a low-temperature, ammonia-free process that is claimed to offer performance advantages for electronics manufacturers including higher-performing, lower-cost devices. The firm recently demonstrated patented ‘active as grown’ RPCVD tunnel junctions for LED wafers. It is reckoned that these tunnel junctions could solve the industry challenge of efficiency droop, by combining multiple LEDs in a single vertical LED stack, generating greater light output for less power.

The joint development program aims to integrate BluGlass and Bridgelux’s technologies in high-performance commercial LED applications, and to ultimately drive commercial adoption of RPCVD-enabled cascade LEDs for general lighting through the future provision of RPCVD equipment and process licensing. The terms of the JDA are non-exclusive and will provide foundry revenue to BluGlass for its development work.

“Bridgelux is a leader in solid-state lighting innovation and is always working on developing new technologies for the LED lighting industry,” says Bridgelux’s CEO Tim Lester. “We look forward to exploring the potential of RPCVD with BluGlass,” he adds.

“We are delighted to have Bridgelux as a development partner to help deliver the competitive advantages of RPCVD tunnel junctions into this important high-growth market,” says BluGlass’ CEO & managing director Giles Bourne. “Bridgelux is an innovative leader producing premium lighting to high-end markets around the globe. This commercial partnership marks an exciting milestone for BluGlass.”
