Abstract

The invention relates to a solar thermoelectric day-lighting device for connecting solar energy by a parabolic cylindrical surface-spotlighted hollow concave closed cavity. The device receives the solar energy through the reflective focusing effect of the parabolic cylindrical surface, can greatly improve the receiving efficiency of the solar energy and can be used for realizing the collection and the receiving of the solar energy under 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 parabolic cylindrical surface concentrating hollow concave closed cavity lighting solar thermoelectric lighting device using the principle of parabolic cylindrical surface concentrating to receive solar energy. Solar energy can greatly improve the receiving efficiency of solar energy. Background technique: [0002] Solar energy is a kind of clean energy, inexhaustible and inexhaustible, and will not cause environmental pollution. Nowadays, whether in coastal cities or inland cities, solar energy products are increasingly entering people's field of vision. Solar street lights, solar lawn lights, solar garden lights, solar corridor lights, bus station lights, traffic lights, etc., all kinds of solar water heaters have also approached thousands of households. However, most of these solar products do not have the function of concentrating light, resulting in low utilizatio...
