Investigation of effects of silica particles on light extraction efficiency of light-emitting diode packaging using ray-tracing simulation

Investigation of effects of phosphor particles on optimal design of surface‐mount‐device light‐emitting diode packaging using ray‐tracing simulation

“…The performance of the white LED PKG is principally determined by the structure [8,9] and optical properties of the PKG components, namely, PKG resin (injection moulding resin), a lead frame (L/F) [10,11], die-bonding paste [12,13], bonding wire [14][15][16], mould resin (silicone or epoxy resin) [17][18][19] containing a phosphor [20][21][22][23][24][25], and diffuser materials [26]. Performance of each PKG component has been improved in development of each area.…”
