摘　　要：提出一种改变LED聚光腔的出光角度来提高单体发光效率的方法,通过建立LED模型,根据半导体产业SMT过程中的相关参数限定,运用tracepro来仿真模拟聚光腔角度改变对LED发光效率影响的关系,从而找到最佳的角度优化参数,研究表明,聚光腔出光角度的变化可以有效的影响LED单体的发光效率,在背光源领域广泛使用的3020型LED做以验证,在同等条件下发光效率可以提升9.32%.A new method was put forward to increase single LED＇s flux efficiency by changing LED light- gathering cavity＇ s reflect - angle. Base on the related standards of SMT process in semi - conductor field, tracepro software was used to simulate the relations between different light - gathering cavities reflect - angle and LED＇ s flux efficiency, and the best angle parameter was found. The research appears that Light - gathering cavity reflect angle＇ s change can affect LED efficiency greatly. Checked with 3020 type LED in back - lighting field, the LED flux efficiency can raise 9.32%.
