Embodiment Construction

[0019] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0020] A flat concentrator, the lower surface 1 is a smooth plane, the upper surface 2 is divided into a plurality of rectangular blocks 3, and at least one slope 4 is arranged in each rectangular block 3, and the tops 41 of the slopes are all close to the center O of the upper surface. The slope bottoms 42 are all away from the center O of the upper surface. In this way, after the sunlight is refracted by the slope, it will gather at the vertical line at the center of the upper surface without diverging the light.

[0021] The four rectangular blocks 3 next to the center O of the upper surface have only one slope 4 . Other rectangular blocks 3 are provided with two or more than two slopes 4, and the top 41 and bottom 42 of the slope 4 in the same rectangular block 3 are straight lines and parallel to each other, and the top 41 of the slope 4 i...

Abstract

The invention discloses a plane condensing board with a smooth lower plane surface, which has the technical key points that, an upper surface is divided into a plurality of rectangular blocks; each rectangular block is internally provided with at least a slope; the top of the slope is close to the center of the upper surface, whereas the bottom of the slope is far away from the center of the upper surface; the four rectangular blocks next to the center of the upper surface is provided with only one slope, while the other rectangular blocks are provided with two or more slopes; the tops and bottoms of the slopes in the same rectangular block are in a straight line and parallel to each other; all the tops and bottoms of the slopes in the same rectangular block are tangential with a virtual circle which takes the center of the upper surface as the circle center and the distance from the top and bottom of the slope to the circle center as the radius. Aiming at overcoming the disadvantagesof complicated production process and high cost of the traditional Fresnel lens, the invention provides a plane condensing board which is transparent, simple, practical, and cheap. Furthermore, the plane condensing board has the advantages of uniform condensation ray, good condensation effect and high condensation intensity.

Description

【Technical field】 [0001] The invention relates to a concentrating panel, in particular to a solar concentrating panel, which belongs to the technical field of optical components. 【Background technique】 [0002] Solar lighting is a photoelectric conversion system, which is called "silicon wafer ground photovoltaic module" in the professional field. The working principle is that the silicon chip receives sunlight and converts it into electrical energy, then stores it in the battery, and then controls it with a photosensitive switch. It can automatically light up when it is dark, and automatically turn off when it is bright. [0003] Focusing solar energy is one of the key steps in solar lighting. Convex lenses can gather sunlight to one point, but the receiving chip is prone to local overheating, expansion, and cracking; convex lenses cannot gather sunlight in a large area. Fresnel lenses are widely used in existing solar energy equipment to focus sunlight. Traditional Fresn...
