摘　　要：使用新型透镜提高LED取光效率是LED封装的研究热点之一。以亚毫米级阵列式微型透镜封装5630TOP LED为研究对象,利用光学仿真软件TracePro,考察了不同尺寸的阵列式圆锥透镜、半椭球透镜和半圆球透镜对LED取光效率的影响。仿真实验结果表明在优化条件下,5630TOP LED的取光效率可提高10.7%,光分布均匀。该仿真结果对下一步亚毫米级阵列式透镜的设计与制造有实际指导意义。Abstract. Improving the light extraction efficiency of LED with various types of lens is the research focus of LED package. Taking sub-millimeter size 5630 TOP LED with lens as the model, the effects of cone arrays, half-ellipsoid arrays and hemisphere arrays with different sizes on the light extraction efficiency were investigated and stimulated by applying stimulation software TracePro. The stimulation results show that under optimal conditions, the light extraction efficiency of 5630 TOP LED can be increased by 10.7% and the light distribution is uniform.
