Abstract

Using the previously developed optimization method for an extended light source [Byzov EV, Kravchenko SV, Moiseev MA, Bezus EA, Doskolovich LL. Optimization method for designing double-surface refractive optical elements for an extended light source. Opt Express 2020; 28(17): 24431-24443. DOI: 10.1364/OE.400609], we designed a compact refractive optical element (the ratio of the element height to the light source size being 1.55) providing a uniform illuminance distribution in a shifted rectangular region. An application of the optimization method for calculating the so-called TIR-elements, exploiting the phenomenon of the total internal reflection of rays, is considered. For an extended light source, compact TIR-elements with freeform exit surfaces that generate uniform illuminance distributions in a rectangular region are designed. The results of the work show promise for a wide class of problems of designing compact optical elements for light-emitting diodes.

扩展光源光学元件的设计

利用先前开发的扩展光源优化方法[Byzov EV, Kravchenko SV, Moiseev MA, Bezus EA, Doskolovich LL]。扩展光源双面折射率光学元件的优化设计方法。Opt Express 2020;28(17): 24431 - 24443。DOI: 10.1364 / OE。[400609]，我们设计了一个紧凑的折射率光学元件(元件高度与光源尺寸之比为1.55)，在移位的矩形区域内提供均匀的照度分布。利用射线的全内反射现象，考虑了计算所谓tir单元的优化方法的应用。对于一个扩展的光源，紧凑的红外元件与自由形状的出口表面，产生均匀的照度分布在一个矩形区域被设计。这项工作的结果为设计用于发光二极管的紧凑型光学元件的广泛问题提供了希望。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
