Paper Abstract

Linear calculation models are proposed and demonstrated to evaluate the color rendering index (CRI) performance associated with the correlated color temperature (CCT) of a white light emitting diode with two phosphors. All the three proposed models are simple and easy, and the error in predicting the CRI is within 1, while the deviation of the CCT is around 300 K and less. Such models can be useful in evaluating the chromatic performance of a specific recipe with two phosphors.
