OPTIS has developed in OptisWorks an editor for LED phosphor dyes which take into account physics based measureable spectra information as well as the volume scattering by the Hyenyey-Greenstein equations. It has been proved that by using this technology it is possible to virtually develop LED phosphor mixtures with the target to achieve specific colors. In case of white LEDs the CRI color rendering index can be measured an optimized automatically. The result is applicable in the case of applying the phosphor directly on the LED chip as well as in the case of remote phosphor applications.
