With the iteration of LED technology, especially the technological updating of Yujileds® phosphors. As a leader in LED spectroscopy engineering, we successfully simulated and commercialized CIE illuminators using a single LED for the first time in the world.

CIE Illuminant D50 is a standardized reference light source developed by the International Commission on Illumination (CIE) to represent average daylight conditions at a color temperature of approximately 5000K. It is commonly used as a benchmark for color-related applications, such as color matching, quality control, and color reproduction in industries like graphic arts, printing, and photography. As a fundamental component in color science, CIE Illuminant D50 plays a crucial role in ensuring consistent and reliable color communication across different media and visual contexts.
