Sunlight collection system capable of realizing self-rotation and directional emission

Abstract

The invention relates to a sunlight collection system capable of realizing self-rotation and directional emission, and belongs to the technical field of energy collection. The system comprises a baseI, a base II, a rotating shaft I, a rotating shaft II, a bracket II, a bracket III, an optical device, a transparent optical shell, a motor and a reflecting mirror. The base I can rotate around the rotating shaft I. The optical center of the transparent optical shell is positioned on the rotating shaft I. The motor is arranged on the base II. The bracket III and the rotating shaft II are used forfixing an optical device of the transparent optical shell, and the transparent optical shell can rotate around the rotating shaft II. The bracket II is used for fixing an optical device. The optical device can rotate around the bracket II to ensure that sunlight is received at the maximum angle. The sunlight collection system with two-dimensional tracking is designed by adopting a self-rotation orientation principle, can be suitable for different types of sunlight lighting-emitting systems, and has the advantages of wide adaptability, compact structure and high light energy utilization rate.

Description

technical field [0001] The invention belongs to the technical field of energy collection, and relates to a sunlight collection system with self-rotating and directional emission. Background technique [0002] At present, there are mainly the following types of collection structures for direct sunlight lighting technology: [0003] (1) Solar fiber optic lighting technology. This technology uses a lens as a sunlight collector, and the lighting system uses a dual-axis tracking method to track sunlight so that the lighting surface is always aligned with the sunlight. This structure makes the terminal of the lighting system, that is, the direction of light output, change accordingly, and the related coupling optical fiber rotates with the rotation of the lighting system, which may easily cause problems such as light leakage caused by excessive bending of the optical fiber or a decrease in reliability at the coupling end. . [0004] (2) Light pipe sunlight lighting technology. ...

AI Technical Summary

Problems solved by technology

One is a prism-type sunlight reflection lighting system, which has the function of sunlight tracking, but its principle cannot ensure that the direction of the outgoing light remains unchanged, and it cannot realize all-round sunlight tracking in terms of structure

One is a one-time reflection or three-time reflection sunlight reflection lighting system. At present, only the lighting principle is explained for this type of lighting system, and there is a lack of a directional and efficient tracking structure, which makes this type of system only in the research stage.
