摘要：

A　Monte　Carlo　ray　tracing　method　is　provided　to　simulate　the　light　extracting　efficiency　of　the　light-emitting　diodes　(LED).　The　simulation　results　for　the　surface　texture　LED　show　that　a　36%　increment　of　the　extracting　efficiency　can　be　reached　by　optimizing　the　texture　parameters.　The　surface　texture　LED　is　fabricated　by　wet　and　dry　etching,　a　20.6%　increment　of　the　axis　light　intensity　is　obtained　for　the　surface　texture　LED.　Both　the　theory　and　the　experiment　results　show　that　the　surface　texture　technology　is　an　effective　method　to　increase　the　LED　light　extracting　efficiency.
