| 摘 要： | 在使用LED作为照明光源的过程中,光场作为LED应用中的关键因素,一般使用二次光学系统进行调控。但是二次光学系统一般设计复杂、体积大、重量重,随着LED光学封装系统朝着小型化方向发展,二次光学系统的应用将会变得困难。结合软件仿真和实验验证探索了用于单片集成发光二极管(MI-LED)的一次光学透镜的光场调控功能。研究结果表明,仿真和实验LED光源的光场几乎重合一致,所设计的一次透镜将LED光源的光束角从120°调控到48°~72°范围内。与未加一次透镜的LED光源相比,加一次透镜的LED光源具有更高的光提取效率和更均匀的空间光色分布。

| Abstract: | In the process of using LED as lighting source, the optical field is the key factor in LED applications and is regulated by secondary optical system, which is complex in design, large in size and heavy in weight. With the development of miniaturization of LED optical encapsulation system, the application of secondary optical system will become more difficult. Combined with software simulation and experimental verification, the optical field regulation function of primary optical lens for the monolithically integrated light-emitting diode (MI-LED) was explored. The research results show that the optical field of experimental LED light sources is almost consistent with that of simulated LED light sources, and the designed primary lens can adjust the beam angle of LED light source from 120° to the range of 48°～72°. Compared with the LED light source without primary lens, the LED light source with primary lens has higher light extraction efficiency (LEE) and more uniform spatial light color distribution. |
