Abstract

The invention relates to a thermoelectric lighting device using a double parabolic cylindrical surface to reflect parallel light and focus solar energy. Due to the reflecting and focusing action of a parabolic cylindrical surface, uniform parallel light of which the intensity is several times higher than that of sunlight is formed and irradiated on solar energy receiving equipment so as to greatly improve the solar energy receiving efficiency. The thermoelectric lighting device can be used for collecting and receiving the solar energy in an environment with strong light and weak light.

Description

Technical field: [0001] The invention relates to a solar energy application technology, in particular to a double parabolic cylinder reflective parallel light focusing solar thermoelectric daylighting device which utilizes the principle of parabolic cylindrical surface concentrating to receive solar energy. Improve solar energy reception efficiency. 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 utilization of solar energy. If the light intensit...
