Plessey Releases New Generation of GaN-on-Si LEDs

Samples now available of LED p/n PLW114050.

Plymouth, England (December 3, 2013) — Plessey announced today availability of its next generation GaN-on-Silicon mid-power LEDs. The product family doubles the efficacy of Plessey’s first generation MAGIC™ (Manufactured on GaN-on-Si I/C) products released in February 2013. Using standard silicon semiconductor production techniques, Plessey is able to achieve high flux output LED products at substantially lower cost. The PLW114050 is the first in a family of entry level LED lighting products that will be released.

“We have made great strides forward in refining, productising and improving our patented MAGIC™ technology,” said Dr. Keith Strickland, Plessey’s Chief Technology Officer. “We have a roadmap that puts MAGIC™ ahead of the efficacies achieved by sapphire-based LEDs and, thereby, sets a new milestone in terms of Lm/$ performance. By approaching efficacy parity, we are accelerating the widespread adoption of GaN-on-Si LED-based lighting products. Our MAGIC™ LED products have a cost advantage over comparable sapphire-based LEDs as we use 6-inch, high yield, standard, automated silicon manufacturing technology.”

Dr. Jose Lopez, Plessey‘s Chief Commercial Officer, said, “Customers are delighted that a European company is committed to developing and manufacturing world class GaN-on-Si LEDs. The market currently has many suppliers of LEDs but the quality and reliability can be variable. Plessey is a trusted brand with a 50-year plus track record of manufacturing products to the highest standards. Our aim is to light the world with MAGIC™ LEDs.”

The PLW114050 product is available in a CCT range from 6500K to 2700K, with a Lambertian distribution in an industry standard 3020 package. With a drive current of 60mA, the PLW114050 has a typical forward voltage of 3.2V. A full datasheet is available on the Plessey website. Plessey also supply the blue LED PLB010050 in sawn-wafer die form. Additional package options will be made available.

URALCHEM and Stamicarbon will develop a New Technology for Urea Production

URALCHEM signed a joint technology development agreement for the synthesis of urea with Stamicarbon, the world’s top developer and licensor of urea processes.

Moscow, Russia (December 2, 2013) — URALCHEM, a leading Russian producer of nitrogen fertilizers, signed a joint technology development agreement for the synthesis of urea with Stamicarbon, the world’s top developer and licensor of urea processes.

The agreement should result in the creation of a new technology that will be available for commercial use globally. It is being built on both Stamicarbon’s intellectual property and URALCHEM’s research cooperation with the Moscow State University Department of Chemistry. URALCHEM has been working with the MSU Dept. of Chemistry on the concept of 100% CO2 conversion since 2008. The new technology will allow producing higher quality urea with less capital expenditure.

Within this joint project, URALCHEM will build, at its Perm Mineral Fertilizers site, a pilot unit designed by Stamicarbon, using the new technology. Subject to the positive evaluation of the pilot plant operations, Stamicarbon will proceed to the basic design of a commercial scale plant.

“This is one of those unique examples in modern Russian history in which a prominent western engineering company utilizes scientific findings of Russian fabricators and academic institutions”, noted Valeriy Lunin, Dean of the Moscow State University Department of Chemistry, member of the Russian Academy of Sciences.
