Embodiment Construction

[0012] Please refer to figure 1 , figure 2 , which provides a solar lighting system 100 according to an embodiment of the present invention. The solar lighting system 100 includes a light collector 10, a first reflected light polarizer 20, a second reflected light polarizer 30, a light reflector 40, a third reflected light polarizer 50, a driving device 60, a controller 70 and a light detector 80.

[0013] The light collector 10 includes a lens system for condensing light. In this embodiment, the light collector 10 includes a first convex lens 102 and a second convex lens 104 . The first convex lens 102 and the second convex lens 104 have a common focus. The first convex lens 102 is used to focus the light to a focal point, and the second convex lens 104 is used to convert the focused light into parallel light.

[0014] The first reflected light polarizer 20 is used for dividing the parallel light into TE polarized light and TM polarized light, the TE polarized light is ...

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.

Description

technical field [0001] The invention relates to lighting technology, in particular to a solar lighting system. Background technique [0002] With the development of green energy technologies, technologies that utilize solar energy to directly illuminate the interior of buildings have emerged. A typical solar lighting system includes a concentrator that collects sunlight and a light guide system that directs the collected sunlight to the interior of a building for illumination. However, conventional solar lighting systems cannot adjust the intensity of the light. SUMMARY OF THE INVENTION [0003] In view of this, it is necessary to invent a solar lighting system with light intensity control function. [0004] A solar lighting system with light intensity control function includes a light collector and first to third reflected light polarizers. This concentrator is used to collect sunlight. The first reflected light polarizer is used for dividing sunlight collected by the...
