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 invention provides a two-level focus sunlight converging device which mainly comprises a first level light converging unit, a second level light converging unit, a support and optical fibers. The first level light converging unit and the second level light converging unit are fixed on the support and are coupled on a sunlight incident light path, wherein the first level light converging unit is used for primarily converging sunlight, and the second level light converging unit is used for converging the sunlight which is converged by the first light converging unit again. The two-level focus sunlight converging device has the advantages that the size of sunlight focus light spots is effectively decreased. Meanwhile, the positions of the silica optical fibers can be adjusted through screws in an optical fiber collimator. Therefore, sunlight with different spectrums can be adjusted to enter the optical fibers, and the purpose of selectively transmitting sunlight spectrums is achieved. The silica optical fibers with small diameters can be used for transmitting, and cost is lowered. Meanwhile, large diameter diaphragms of the optical fiber collimator can effectively lower the requirement for following precision, and the positions of the optical fibers in the optical fiber collimator can be adjusted to selectively transmit the light spectrums of the sunlight.

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...
