介绍了一种小角度LED高效配光镜组及阵列，每个配光镜组包含一个发光芯片、反光碗和收光透镜，发光芯片发出的散射光经过反光碗和透镜的二次配光后会聚。LED阵列是由多个配光镜组列阵而成，并给出了其设计方案与软件仿真结果。经过多次工艺试验及批量生产后验证表明，该LED高效配光镜组及阵列设计方案正确、可行，能够高效收集光能量，并最大限度收缩发光角（θc≤10\O），大大提高了光能利用率，具有二次配光光学组件尺寸小，安装方便的优点。列阵配光后的LED在远场形成均匀的面阵照明，特别适合中远距离的均匀照明系统。

The design of efficient matched mirrors and arrays for small angle LED is introduced. The matched mirrors include a light emitting chip, a reflector and a receiving lens. The scattering light emitted from the light emitting chip is focused by secondary match of the reflector and lens. The LED arrays are generated by permutation of several matched mirrors. The design scheme and simulation results are also presented. By the repeating technological tests and batch production tests, the design scheme of LED efficient matched mirrors and arrays is valid and feasible. The advantages of this scheme are the highly efficient collection of the light energy and the almost concentrated radiant angle. The light extractive efficiency has been greatly improved, and the secondary matched optical modules are easy to install with small size. The LED arrays provide a uniform area array illumination in the long distance, which is particularly suited to uniform illumination for middle & long distance.
