Abstract

The invention relates to a light-collecting solar power generation device with a secondary reflection disc closed cavity. The device receives solar power through the light reflection focusing actions of a large plane reflecting mirror and a spinning paraboloidal reflecting mirror, so that the receiving efficiency of solar power can be increased greatly, and the device can be used for realizing the collection and the receiving of solar power in the environments of strong light and weak light.

Description

Technical Field: [0001] The invention relates to a solar energy application technology, in particular to a secondary reflective disc-shaped closed cavity daylighting solar power generation device that uses the principle of rotating paraboloid to receive solar energy. The device receives solar energy through the reflective focusing action of the rotating parabola, which can greatly Improve solar energy receiving efficiency. Background technique: [0002] Solar energy is a kind of clean energy, inexhaustible, inexhaustible, and will not cause environmental pollution. Nowadays, solar products are increasingly entering people's field of vision, whether in coastal cities or inland cities. Solar street lights, solar lawn lights, solar garden lights, solar corridor lights, bus station desk lights, traffic signal lights, etc., various solar water heaters have also reached thousands of households. However, most of these solar products do not have a light-gathering function, resulting in ...
