Edison Innovations, a Dominion Harbor Enterprises (DHE) (www.DominionHarbor.com) company, has licensed its portfolio of Potassium Fluorosilicate (PFS/KSF) phosphor technology patents to the leading American LED industry developer-manufacturer Bridgelux (www.Bridgelux.com), which is affiliated with the world’s largest LED manufacturer, MLS Co., Ltd. The agreement was jointly announced by David Pridham, Chief Executive Officer of Dominion Harbor Enterprises, and Dr. Yi-Qun Li, CEO of Bridgelux.
Bridgelux will apply Edison Innovations’ PFS/KSF patents toward the design and supply of industry-standard, high-performance LEDs to its customers in premium display markets. The long-term agreement provides Bridgelux with the IP foundation to invest confidently in the next-generation KSF-based LED ecosystem, while reinforcing Edison Innovations' position as the industry's leading licensor of KSF display technology.
The Edison Innovations PFS/KSF phosphor LED patent portfolio represents the display industry’s largest collection, as part of the 2,500 patent assets acquired by Dominion Harbor in 2025 from Dolby Laboratories, Inc., after their acquisition of GE Licensing. Following this acquisition, Edison Innovations has actively engaged with technology innovators across various high-growth sectors, including display technology, hybrid and electric vehicles, semiconductors, electronics, batteries, wireless power, wireless networking, and healthcare.
LED technology continues to dominate US display and lighting markets by delivering highly saturated colors and exceptional energy efficiency. Grounded in breakthroughs pioneered by companies like Bridgelux, LEDs bring significant benefits to consumers and professionals alike, including unmatched color realism, superior energy efficiency, and enhanced commercial reliability.
"Adding Bridgelux to our KSF licensing program is a milestone in two respects: they're our first U.S. licensee, and they're a flagship partner for the program. As a vertically integrated, engineering-driven LED company, they understand better than anyone how essential KSF has become to the next generation of displays,” said Mr. Pridham.
"Bridgelux was an early licensee of GE’s PFS patents for general lighting, and today Bridgelux is a leader in the high-CRI LED (SMD, filament, and COB) market due to our innovations in applying KSF phosphor in LED packages for high efficacy and reliable performance in moisture environments. KSF has become essential to the color quality our customers expect in residential lamps and retail downlights. Pairing Edison Innovations' KSF portfolio with Bridgelux's own solutions gives us long-term certainty as we build the next generation of high-performance platforms for display markets," said Dr. Li.
