At the heart of every white LED is a phosphor—a material that converts blue LED light into a broader spectrum. Innovations in phosphor technology are silently driving major improvements. New phosphor formulations are achieving higher Color Rendering Index scores and more consistent color from batch to batch. They are also enabling a wider gamut on the color triangle for more saturated and vibrant colored lighting. Research into narrow-band red phosphors is crucial for improving the efficiency and quality of warm-white LEDs and for horticultural lighting. These advancements in phosphor science are critical for meeting the increasing market demand for light quality that matches or exceeds traditional sources, making it a key, albeit less visible, battlefield for competitive advantage among LED chip and component manufacturers.
