GaN-on-Silicon Substrate Patent Investigation - Knowmade & Yole See More Players on the Playground

Evolution of patent publications related  to GaN-on-Si technology from the earliest beginning in the seventies until today GaN-on-Si technology appeared naturally as an alternative to GaN-on-Sapphire—the main stream technology for LED applications. Today, despite potential cost benefits, the mass adoption of GaN-on-Si technology for LED applications remains unclear. Most major LED makers have a patenting activity related to GaN-on-Si technology, but so far, few have made it the core of their strategy and technology roadmap. Contrary to the LED industry, we expect GaN-on-Si to be widely adopted by Power Electronics and RF applications because of its lower cost and CMOS compatibility. Read more »

Cree Licenses Remote Phosphor Patent Portfolio to NNCrystal

Cree, Inc. announced it signed a non-exclusive worldwide license agreement with Hangzhou Najing Technologies, Ltd. (NNCrystal US Corp.) that provides access to Cree’s remote phosphor patent portfolio. The licensed family of patents addresses the fundamental combination of a blue LED and a remote phosphor element to produce white light, as well as the manufacture, design and placement of the optical element, enabling lighting manufacturers that use NNCrystal’s remote phosphor optical elements to manufacture remote phosphor-based LED lights without taking a separate remote phosphor patent license from Cree. Product time to market can be shortened by using Cree’s patented technology and by using NNCrystal’s licensed remote phosphor optical elements to access the technology. Read more »

Research and Markets Offers LED Lighting - Key Patent Analysis: Remote Phosphor

LEDs, which are semi-conductor devices that convert electricity into light by the properties of compound semi-conductors, have higher energy efficiency and cost less for replacement due to longer lifetimes than existing lighting systems, and have high resistance to impact or vibration. Furthermore, LEDs have advantages in terms of energy saving and protection of the environment since they do not use toxic substances such as mercury, which give an impetus to their market entry as new lighting systems to replace existing lighting systems.
