Abstract:
We present an optical ray-tracing study which investigates the influence of the refractive indexes of the matrix and the phosphor materials as well as the phosphor particle sizes of the color conversion elements (CCE) on the radiant flux of phosphor-conversion-based white light-emitting diodes. We show that an appropriate combination of those parameters is a crucial factor in order to optimize device efficacy.
