Abstract
This study presents investigation of effects of phosphor particles on optimal structure and optical design of surface-mount-device (SMD) light-emitting diode (LED) packaging (PKG) using ray-tracing simulation. In the authors’ previous study, effects of the reflection properties of the PKG resin and the lead-frame silver plating on the light extraction efficiency was investigated, and the optimisation method of the cavity angle composing the light reflector of the PKG was proposed. In this study, the optimal cavity angle and reflection properties under the condition of phosphor particles present in mould resin of the top-view PKG are investigated. In addition, the better conditions of the reflection properties under the conditions in which the phosphor is contained and not contained in the mould resin are confirmed. Finally, an optical design method of the SMD LED PKG with the mould resin containing a phosphor is proposed on the basis of the simulation results.
