Light extraction from two-dimensional objects is discussed. Analytical calculations in terms of three different parameters have been applied to equiangular polygons to trace light rays during multiple reflections in a polygon. Based on the result that there are a finite number of incident angles in a polygon for a light ray, it was found that the triangle has the least chance to trap light rays among the polygons. The discussion has been extended to parallelograms, which have an advantage in light extraction to rectangles. Placement of a possible light source in polygons is discussed.
讨论了从二维物体中提取光的问题。已针对等角多边形应用了基于三个不同参数的解析计算，以追踪多边形中多次反射期间的光线。基于多边形中光线的入射角数量有限这一结果，发现三角形在多边形中捕获光线的机会最少。讨论已扩展到平行四边形，平行四边形在光提取方面比矩形具有优势。还讨论了多边形中可能光源的放置问题。
