Sunlight illumination system having light intensity adjustment function

Abstract

A sunlight illumination system includes a light collection device, a first light reflection polarizer, a second light reflection polarizer, and a third light reflection polarizer. The light collection device collects sunlight. The first light reflection polarizer splits the collected sunlight into a TE polarized light and a TM polarized light. The TM polarized light transmits through the first light reflection polarizer. The TE polarized light is reflected by the first light reflection polarizer. The TM polarized light is perpendicular to the TE polarized light. The second light reflection polarizer is positioned in an optical path of the TM polarized light and is rotated to adjust a light intensity of the TM polarized light. The third light reflection polarizer is positioned in an optical path of the TE polarized light and is rotated to adjust a light intensity of the TE polarized light.
