Document Type and Number:
WIPO Patent Application WO/2019/131087
Kind Code:
A1
Abstract:
Provided is a solar energy using apparatus that is able to use solar energy more efficiently. In the present invention, a solar energy using window is provided with two plate members, and a first prism (30) and an energy collection part (40) disposed between the two plate members. The energy collection part (40) is disposed with a predetermined space C1 from a second side (30b) of the first prism. In a triangular prism, refractive indexes and triangular interior angles are set such that with respect to sunlight beams that pass through an exterior glass (10a) to enter the first prism from a first side (30a), there are three types of optical paths OP1 to OP3 for: a beam that directly reaches the second side (30b) and goes out of the first prism from the second side; a beam that is totally reflected on a third side (30c), reaches the second side, and goes out of the first prism from the second side; and a beam that is totally reflected on the third side and the first side in this order, then reaches the second side, and goes out of the first prism from the second side.
