Abstract

The invention discloses a large-caliber reflection-type light guide machine and a working method thereof, belonging to the technical field of solar energy application. The large-caliber reflection-type light guide machine consists of an azimuth angle drive device, a height angle drive device, a focus lens group, a sun location system, a focusing device and an optical fiber beam. The focusing device is used for adjusting a receiving end surface of the optical fiber beam to a focal point of the focus lens group, and the focus lens group is driven by the azimuth angle drive device and the height angle drive device, so that the focus lens group can follow the sun, the infrared ray in the incidence light is eliminated by utilizing a filter lens of the focus lens group, and the uniformity of the intensity of the focus spot can be realized by virtue of a light homogenizing cavity of the focus lens group; the sun location system adopts a photosensitive element to provide a sun roughly location signal and utilizes a high temperature sensor to provide a precise position signal of the focus spot. By adopting the large-caliber reflection-type light guide machine, the infrared ray in the sun focus light is eliminated, the uniformity of the intensity of the focal spot can be realized, the service life of the optical fiber beam can be greatly prolonged, and the position detection reliability of the focus spot can be improved by utilizing the high temperature sensor.

Description

technical field [0001] The invention belongs to the technical field of solar energy utilization, and in particular relates to a large-diameter reflective light guide and a working method thereof. Background technique [0002] The light guide machine is a device that effectively collects sunlight and uses optical fibers to transmit it to places that require lighting. This lighting technology is energy-saving, photoelectrically isolated, very safe, and its spectrum is also suitable for human health needs. The core idea of ​​this type of technology is to use a condenser lens or a condenser mirror to focus the sunlight onto the optical fiber, and use the optical fiber to transmit the sunlight to the place that needs to be illuminated. However, in practical applications, it is necessary to consider the life of the fiber bundle, the reliability of tracking, and the large aperture. So far, there are many related studies. [0003] Sunlight conduction lighting is a subject of long-...
