Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0018] For ease of understanding, the principle of the present invention will be described in detail below in conjunction with the structure of the two-stage focusing solar concentrating device that is the same as the principle of the solution of the present invention.

[0019] like figure 1 As shown, a two-stage concentrating solar light concentrating device of the present invention includes a first-stage concentrating unit 1 , a second-stage concentrating unit 3 , a bracket 2 and an optical fiber 6 . The first-level concentrating unit 1 and the second-level concentrating unit 3 are fixed on the bracket 2 and coupled on the incident light path of the sun. Specifically, the light-receiving surface of the second-level concentrating unit 3 is located at the first-level concentrating Near the focal point of the unit, it is limited to be able to ...

Abstract

The two-stage concentrating sunlight concentrating device of the present invention mainly includes a first-stage concentrating unit, a second-stage concentrating unit, a bracket and an optical fiber; wherein the first-stage concentrating unit and the second-stage concentrating unit are fixed on the bracket , and coupled on the incident light path of the sun, wherein the first-level concentrating unit is used to initially condense sunlight; the second-level concentrating unit is used to re-condense the sunlight collected by the first-level concentrating unit. The beneficial effect lies in that the size of the focused spot of sunlight is reduced. At the same time, the position of the silica fiber can be adjusted through the screw on the fiber collimator, so that sunlight of different spectra can be adjusted to enter the fiber, and the purpose of selectively transmitting the solar spectrum can be achieved. Transmission can be carried out through small-diameter silica optical fibers, reducing costs. At the same time, the larger aperture stop of the fiber collimator can effectively reduce the requirements for tracking accuracy. The spectrum of sunlight can be selectively transmitted by adjusting the position of the fiber in the fiber collimator.

Description

technical field [0001] The invention relates to solar energy utilization technology in the new energy field, relates to a solar lighting system, in particular to a two-stage focusing solar concentrating device. Background technique [0002] Traditional solar concentrating technology usually uses a single-stage lens for concentrating sunlight. Due to the poor focusing effect of this converging technology on sunlight, there are disadvantages such as a large spot area after focusing, and usually multiple large-diameter silica optical fibers are required for transmission in order to ensure the transmission effect. However, the price of large-diameter silica optical fibers is very expensive, so traditional solar concentrating equipment is expensive. The traditional optical fiber sunlight introduction system generally needs six 1um diameter quartz optical fibers to introduce enough sunlight, and the price of 1 micron diameter quartz optical fiber is several hundred yuan per meter...
