摘要：

This　paper　introduces　a　way　of　decreasing　total　reflection　by　roughening　upper　surface　of　an　LED.　The　expected　surface　morphology　is　achieved　by　wet　chemical　etching.　The　light　power　and　light　intensity　were　measured.　The　light　power　is　enhanced　by　about　29%.　The　effect　of　roughness　on　enhancing　red　LED＇s　external　quantum　efficiency　is　demonstrated　both　theoretically　and　practically.
