In recent years, energy efficiency has become a shared worldwide goal. As a result, requirements for device luminous efficiency regarding high standard LED filament bulbs have become stricter. The contemporary fluorescent systems have encountered limitations. Now, a new Powder powered solution is at the works.
Powdered light: introducing a new series of LED light sources with high CRI, high R9 value, excellent luminous efficiency, and reliability. These products designated towards the red light spectrum, certified by LM80, will provide the best lighting solutions for retail, hotels, and other high end commercial lighting applications. This is due to an agreement of a patent application authorization for KSF (PFS) fluorescent powder between lighting revolutionary REFOND Optoelectronics and Current Chemical Company. Now, cutting edge KSF technology has been introduced to a series of LED light sources with high Color Rendering Index (CRI), high R9 value (Reproduction of strong red light value), excellent luminous efficiency, and reliability.
Namely, this phosphor technology will enhance LED packaging efficiency, improve light color quality, and reduce packaging costs. Not as traditional nitride phosphors, these fluoride (KSF) phosphors have a narrow half width emission spectrum, and their excitation spectrum has minimal absorption in the green light segment. This reduces re absorption issues of aluminum silicate yellow/green phosphors in packaging applications, resulting in a beneficial effect of improving product brightness. These LEDs had been enhanced with a 10% to 20% increase in luminous efficiency (@Ra90). Under same parameters, high CRI LED light sources using KSF phosphor consume less energy, assisting users in energy savings and maintenance cost reduction.
The first manufacturer in China to ever receive such GE global patent authorization for KSF phosphor application back in 2016, the road now is clear to introduce more high efficiency, high CRI, and high quality LED light sources. Thus, contributing to the global goals of energy efficiency and carbon reduction. It is just the beginning for better product brightness, as minimal absorption in the green light segment means reductions in reabsorption issues of aluminum silicate yellow/green phosphors in packaging applications.
