Company patents

CURRENT LIGHTING SOLUTIONS, LLC

CURRENT LIGHTING SOLUTIONS, LLC's patent strategy reveals a surprising diversification beyond core lighting, with significant activity in 'Sterilization & Biocompatible Materials' (19.6% of portfolio) and 'Functional Materials (LCD, Lubricants)' (19.6% of portfolio), both showing volatile but notable patenting. While 'Lighting Devices (Functional Features)' remains the largest category at 33.3%, the company also demonstrated an emerging focus in 'LED & Optoelectronics (Legacy CPC)' with a 400.0% YoY growth in 2024, though this has since declined, and so far in 2026, patenting across most categories has seen a sharp decline.

Systems and methods for fluoride ceramic phosphors for LED lighting

Filed:2023-11-07Pub:2025-08-26
Applicant:Lawrence Livermore National Security, LLC

The present disclosure relates to a lighting component which may comprise a light emitting diode (LED) or laser diode (LD) for generating at least one of blue light or ultraviolet light. A fluoride phosphor matrix may be included, which may be consolidated into a phosphor ceramic structure including at least one of a transparent fluoride ceramic structure or a translucent fluoride ceramic structure, and positioned adjacent to the LED or LD. The phosphor ceramic structure generates at least one of red or orange light when irradiated by the light emitted from the LED or LD. The phosphor ceramic structure exhibits reduced thermal quenching relative to a fluoride particulate structure irradiated by the LED or LD.
