Lumileds LLC of San Jose, CA, USA says that its new LUXEON HL2X-V is the latest result of its commitment to addressing lighting manufacturing issues. Many manufacturers with high-power LED solutions are considering re-engineering their designs with mid-power LEDs to take advantage of their lumen/$ position. Now, with LUXEON HL2X-V, manufacturers can achieve lm/$ ratios similar to mid-power products without spending valuable resources on redesigning or re-engineering, says the firm...

Multi-color LED fixtures based on a large LED cluster under a single optical system are preferred in many situations for their ability to deliver highly accurate illumination with superior beam quality. Until now, however, LED design has not allowed engineers to address the conflicting needs and challenges inherent to close-packed, high-power LEDs...

Infinera Corp of San Jose, CA, USA — a vertically integrated manufacturer of open optical networking systems and optical semiconductors — says that its pending acquisition by Nokia Corp should be completed on or about 28 February, subject to receipt of remaining outstanding regulatory approvals and the satisfaction of other remaining customary closing conditions...

Sivers Semiconductors AB of Kista, Sweden (which supplies RF beam-former ICs for SATCOMs and photonic lasers for AI data centers) has appointed Alexander McCann as a strategic senior advisor to the board and the CEO. His primary focus will be strengthening and scaling photonics operations...

Fabless firm Cambridge GaN Devices Ltd (CGD) — which was spun out of the University of Cambridge in 2016 to design, develop and commercialize power transistors and ICs that use GaN-on-silicon substrates — has closed a $32m Series C funding round led by a strategic investor with participation from British Patient Capital and supported by existing investors Parkwalk, BGF, Cambridge Innovation Capital (CIC), Foresight Group, and IQ Capital...

Since gallium nitride (GaN) suppliers have taken various approaches to package types and sizes, leading to fragmentation and a lack of multiple footprint-compatible sources for customers, Infineon Technologies AG of Munich, Germany has launched the high-performance CoolGaN G3 Transistor 100V in RQFN 5x6 package (IGD015S10S1) and 80V in RQFN 3.3x3.3 package (IGE033S08S1)...
