This paper reports an investigation of the effects of silica particles contained in mold resin to the light extraction efficiency of light-emitting diode (LED) packaging (PKG) using ray-tracing simulations. The light extraction efficiencies, namely, luminous and radiant flux of the rays emitted from the PKG, are improved with the silica particles. The silica particles cause the scattering of the rays in the mold resin of the LED PKG. If the scattering can be generated properly, the light extraction efficiency can be improved. Varying the volume percentage of the silica particles, its effects to the light extraction efficiency are confirmed. Finally, we could confirm the improvement of luminous higher than 0.5 lm and radiant flux higher than 0.02 W respectively from the simulation results.
