Plessey today announced that its MAGIC™ GaN-on-Silicon technology has successfully achieved light output of 120 Lumens per watt with greater than 50% light output efficiency.
Plessey's first engineering samples in the 5630 PLCC2 package are now shipping with other package variants available on demand. Blue die with a wavelength of 455nm are also available and being shipped to lead customers.
Dr. Keith Strickland, Plessey CTO, said, "Having developed and put into production the first of our MAGIC LEDs in 2013, the next step was to demonstrate that the GaN on silicon technology could deliver output performance levels comparable with other LED technologies. Whilst 120 Lumens per Watt for an LED may be considered "acceptable" to industry, we must remember that we have doubled our LED light output in the past six months. I see no reason why we cannot reach state of the art in LED die output performance within the next six months. This current process technology will become the base for our Application Specific LEDs, the ASLED that bridges the gap between the LED component suppliers and the solid state lighting fixture designers and OEMs."
Mike Snaith, Plessey Operations Director, commented, "Achieving greater than 50% light output efficiency is a superb achievement for the team here in Plymouth. The combination of expertise and a sustained period of light output performance improvement in the core LED material is due to our holistic approach to LED development -- our in-house experts in epitaxy growth, process development and die design all working together. This way of working will continue and strengthen as we drive towards the next generation of higher efficiency, silicon-based, integrated LED solutions and away from discrete, plastic-packaged LED components."
Plessey's range of products for lighting applications will be showcased at LuxLive, ExCel London, 19-20 November, Stand D31. The show will open on Wednesday 19th November from 9am to 9pm and on Thursday 20th November from 9am to 5pm. The show is free to attend. For free tickets please visit: http://www.luxlive.co.uk/register-2014/. There will be innovative demonstrations by technical and design experts for Plessey's LED technology at the stand. This is an opportunity to gain a deeper understanding of Plessey's latest products and solutions for the commercial, industrial, consumer and wearable lighting segments.
Plessey's MaGIC™ (Manufactured on GaN-on-Si I/C) LED technology has won numerous awards for its innovation and ability to cut the cost of LED lighting by using standard silicon manufacturing techniques.
