利用斯涅尔定律、费马原理,针对点光源模型,通过数学建模得到准直全内反射(Total internal reflection, TIR)透镜的母线,再通过设计复眼透镜来控制其出射光的发散角。利用3D软件完成复眼TIR透镜建模,并将其与扩展光源3030 LED配合使用,经光学软件模拟验证,达到了设计要求。最后讨论并分析了复眼透镜孔径值、复眼透镜的排列密度对出发光角度、中心光强的影响,其结论有助于缩短此类透镜的开发周期。

The generatrix of collimating total internal reflection ( TIR) lens is obtained against point source model via mathematical modeling with Snell’s law and Fermat principle, and then the fly-eye lens is designed to control the divergence angle of the emergent light. The TIR lens is modeled with 3D software and used in conjunction with extended source 3030 LED. The design meets the requirements after the simulation verification of optical software. Finally, the effects of aperture value of fly-eye lens and arrangement density on light-emitting angle of the emergent light and central light intensity are discussed and analyzed. Its conclusion helps to reduce the development period of such lens.
