Future Performances in CRI for Indoor and CCT for Outdoor Lighting
Today, color rendering index (CRI) ≥80 is commonly used in Indoor LED lighting applications and the technology trend is moving to CRI ≥90 and soon ≥95. Additionally, Outdoor LED lighting applications are expanding from street luminaires to architectural and city center lighting, requiring lower correlated color temperature (CCT) performances. In this paper, we introduce the world’s first Ultra-High CRI LED, with all R indices ≥90 and we are covering a possible technical solution to reach CRI up to 100. The paper is also giving an outlook of the continuous technology improvements of phosphor for CCT ≦3000K.
