Abstract
本发明涉及一种太阳能光纤集光装置，其包括多个用以接收并汇聚光线的聚光器及一个光电转换单元，该光电转换单元包括一个受光面，该太阳能集光装置还包括多根光导管，每根光导管具有第一端与第二端，该第一端位于对应的聚光器的焦点处并用于接收由该对应的聚光器汇聚的光线，该第二端用于将该汇聚的光线输出至该受光面。该太阳能集光装置通过多个聚光器与多个光导管的组合将光线汇聚于光电转换单元的受光面，因此，在无需增加单个聚光器面积的前提下，增加了该集光装置的集光面积，提高了光线的利用率。
The invention relates to a solar optical fiber light collecting device, which includes a plurality of concentrators for receiving and converging light and a photoelectric conversion unit, the photoelectric conversion unit includes a light receiving surface, and the solar light collecting device also includes a plurality of light Each light pipe has a first end and a second end, the first end is located at the focal point of the corresponding concentrator and is used to receive light converged by the corresponding concentrator, and the second end is used to The collected light is output to the light-receiving surface. The solar concentrator gathers light on the light-receiving surface of the photoelectric conversion unit through the combination of a plurality of concentrators and a plurality of light guides. Therefore, without increasing the area of a single concentrator, the light concentrator increases The light-collecting area improves the utilization rate of light.
Description
Technical field
The present invention relates to a kind of light collecting device, relate in particular to a kind of solar concentrating device.
Background technology
Because global energy consumption is quick, the utilization of solar energy becomes the target of human development.The mode of the simplest general increase solar panels light harvesting area is that solar panels are placed near the focus of lens, but this moment, the light harvesting area equaled the size of lens.So want to increase its light harvesting area, will make accordingly large lens.Large its curvature of lens can diminish, and causes the focal length of lens elongated, and corresponding lens take up space and become large, moreover lens are produced extensively very much difficult.
Summary of the invention
In view of foregoing, be necessary to propose to increase in a kind of situation not changing the lens size solar concentrating device of light harvesting area.
A kind of solar concentrating device, it comprises a plurality of in order to receive and to converge concentrator and a photoelectric conversion unit of light, this photoelectric conversion unit comprises a sensitive surface, this solar concentrating device also comprises many photoconductive tubes, every photoconductive tube has first end and the second end, this first end is positioned at the focus place of corresponding concentrator and is used for receiving the light that is converged by this corresponding concentrator, and this second end is used for exporting this light that converges to this sensitive surface.
Compared to prior art, solar concentrating device of the present invention converges at light (such as sunlight) by the combination of a plurality of concentrators and a plurality of photoconductive tubes the sensitive surface of photoelectric conversion unit, therefore, need not to increase under the prerequisite of single concentrator area, increase the light harvesting area of this light collecting device, improved the utilance of light.

Following embodiment further specifies the present invention in connection with above-mentioned accompanying drawing.
Embodiment
See also Fig. 1, one embodiment of the invention provides a kind of solar concentrating device 100.This solar concentrating device 100 comprises and a plurality ofly connects corresponding concentrator 20 and the photoconductive tube 40 of photoelectric conversion unit 30 in order to the concentrator 20 that receives and converge sunlight 10, photoelectric conversion unit 30 and many.Wherein the quantity of concentrator 20 is corresponding with the quantity of photoconductive tube 40.This photoelectric conversion unit 30 comprises sensitive surface 31.
This concentrator 20 is used for converging sunlight 10.This concentrator 20 is collector lenses, for example convex lens, Fresnel Lenses or compound paraboloidal mirror (compound parabolic concentrator, CPC) etc.In a word, this concentrator 20 can converge sunlight 10.Each concentrator 20 has respectively focus separately, and photoconductive tube 40 corresponding to collocation.This photoconductive tube 40 has first end 41 and the second end 42.First end 41 and the second end 42 are positioned at the opposing both sides of photoconductive tube 40.In the present embodiment, photoconductive tube 40 is optical fiber.The first end 41 of photoconductive tube 40 places the focus place of corresponding concentrator 20 and is used for receiving the sunlight 10 that is converged by this corresponding concentrator 20.Sunlight 10 enters from the first end 41 of this photoconductive tube 40, enters the light in the photoconductive tube 40 because the Refractive Index of Material of photoconductive tube 40 is large, sunlight 10 because of the total reflection effect constantly in photoconductive tube 40 interior transmission, then from the second end 42 outgoing of photoconductive tube 40.This second end 42 of many photoconductive tubes 40 draws in this photoelectric conversion unit 30 and with sensitive surface 31 and contacts to be used for exporting emergent ray to sensitive surface 31.Photoelectric conversion unit 30 is solar panels in the present embodiment.This photoelectric conversion unit 30 is received from the light of these photoconductive tube 40 outgoing, then carries out light to the conversion of electricity, produces electric power, for the user.
As from the foregoing, above-mentioned solar concentrating device 100 converges at sunlight 10 by a plurality of concentrators 20 and the combination of many photoconductive tubes 40 sensitive surface 31 of photoelectric conversion unit 30, therefore, need not to increase under the prerequisite of single concentrator 20 areas, increase the light harvesting area of this solar concentrating device 100, improved the utilance of sunlight 10.In addition, the focal point that this solar concentrating device 100 had each concentrator separately in 20 minutes, and separately transmission light conduit of collocation, advantage is that each concentrator 20 can both receive light direction by capable of regulating along with the continuous variation of the sun (light source) position, has at any time best collection efficiency.
In addition, those skilled in the art also can do other variation in spirit of the present invention, as in other embodiments, the second end can with sensitive surface separately, spacing distance is visual determines to guarantee that bringing out the light of penetrating from second can try one's best and received by sensitive surface from the second scattering angle that brings out the light of penetrating; Or the optional photodiode of using of photoelectric conversion unit; Or photoconductive tube also can be selected such as other photoconductive tubes such as flexible optical waveguide etc.Certainly, the variation that these are done according to spirit of the present invention all should be included in the present invention's scope required for protection.
