Abstract

The invention relates to a plane lighting and secondary reflection solar water heater which receives solar energy based on the reflection and focusing effects of large-plane reflectors and rotary parabolic reflectors. The invention can greatly improve the solar energy receiving efficiency and can be used for realizing solar energy collection and receiving under high light and weak light environments.

Description

Technical field: [0001] The invention relates to a solar energy application technology, in particular to a planar daylighting secondary reflection solar water heater which utilizes the principle of concentrating light of a rotating parabola to receive 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 utilization of solar energy. If the light intensity on the surface of the solar receiving element is doubled, the receiving efficiency of...
