LED发光系统及发光方法
摘要：
本发明提供一种LED光源系统，包括n个LED偏振光源、n－1个偏振光合束装置，以及分别设置在相邻偏振光合束装置之间的光路上的n－2个偏振光转换装置，偏振光转换装置用于将入射的光束转换成具有同一偏振方向的线偏振光，n为整数，n≥2，第i个偏振光合束装置设在所述第i+1个LED偏振光源的输出光路上并与其相对应，i为整数，1≤i≤n－1；第1个LED偏振光源输出的光射到所述第1个偏振光合束装置中，所述第2－第n个LED偏振光源输出的光分别入射到与其对应的偏振光合束装置中；第j个偏振光合束装置输出的光束经过第j个偏振光转换装置后入射到第j+1个偏振光合束装置中，j为整数，1≤j≤n－2；由第n－1个偏振光合束装置输出的光束作为所述LED光源系统的输出光。
摘要（英）：

The invention provides an LED light source system, which comprises n LED polarized light sources, n-1 polarized light combiners and n-2 polarized light converters arranged on light paths between adjacent polarized light combiners respectively, wherein the polarized light converters are used for converting incidence beams into linearly polarized light having the same polarization direction, n is an integer more than or equal to 2, the ith polarized light combiner is arranged on the output light path of the i+1th LED polarized light source and is corresponding to the i+1th polarized light source, and i is an integer more than or equal to 1 and less than or equal to n-1; the light output by the first LED polarized light source is projected into the first polarized light combiner and the light output by each of the second to nth LED polarized light sources is projected into a corresponding polarized light combiner; the light beam output by the jth polarized light combiner passes through the jth polarized light converter and is projected into the j+1th polarized light combiner, and j is an integer more than or equal to 1 and less than or equal to n-2; and the light beam output by the n-1th polarized light combiner serves as the output light of the LED light source system.
