Intematix Corporation based in Fremont, California USA, has demonstrated a phosphor blend that it says provides a near perfect color rendering index (CRI) of 98 and R9 value of 99 when applied to a reference LED package.

The 98 CRI milestone was demonstrated in Intematix's laboratories using a blend of three of the company's patented phosphor product platforms.

CRI is a light quality measurement grading how well a light source renders color on a scale of 1 to 100 with sunlight producing a CRI reference of 100. Intematix says the achievement paves the way for designers to develop LED lighting systems for retail, hospitality, residential and museum locations to enhance the appearance of apparel, environments, skin tones, and artwork.

"Reaching 98 CRI is huge -- it means that by adding Intematix phosphor, an LED package can render true color," said Dr. Yiqun Li, chief technology officer and executive vice president at Intematix. "That's the efficiency of Silicon Valley with the light quality demanded by the finest New York City gallery, Milan boutique or Hong Kong hotel. This benchmark gives our customers the ability to create the highest quality lighting designs and fixtures."
