ZemosLED Launches 80,000 Hour LED Package
ZemosLED has announced the US launch of the patented, 80,000 hour Zemos9090 LED package. The Zemos9090 has seen extensive use in the company's own line of lighting fixtures with extended lifespans, but has not previously been available to third parties as a discrete component. The company anticipates strong demand from manufacturers of intermediary LED components, and end lighting products, who have been limited by current technology to a 50,000 ...
New British technology will cut the cost of LED lighting
Plessey has acquired CamGaN Limited, a University of Cambridge spin-out formed to commercialisenovel technologies for the growth of gallium nitride (GaN) high-brightness LED drivers on large-area silicon substrates. The acquisition will enable Plessey to exploit synergies with its 6-inch processing facility in Plymouth, England to produce HB LEDs based on CamGaN's proprietary 6-inch GaN-on-silicon technology. The Company believes this acquisition...
