Abstract
The invention discloses a solar tile-shaped grooved cylindrical light-gathering device, which comprises multiple groups of cylindrical Fresnel lenses, a grooved light-gathering funnel and a solar photovoltaic cell, wherein the cylindrical Fresnel lenses are connected together. A circular-arc glass tile is formed on an ultra-white glass plate, and linear stripes are carved on the arch-shaped inner surface of the glass tile to form small prisms of different sizes at unequal intervals, so that incident light rays of the sun become a light focal strip after being refracted and a cylindrical Fresnel lens is formed; once the focal strip is deviated from the cell along with continuous change of the azimuth angle of sunlight, the focal strip falls on a reflecting surface of a lower grooved light-gathering funnel; and after being reflected by the reflecting surface, the focal strip still falls on a solar cell panel at the bottom. A certain included angle is formed between the reflecting surface and the vertical surface of the grooved light-gathering funnel, and a light-gathering focal strip falling on a radiating surface still falls on the photovoltaic cell at the bottom after being reflected by adjusting the included angle, so that the light-gathering effect is achieved.
