Device for guiding solar radiation

摘要

The invention relates to a reflection device that can track the location of sun, focusing solar radiation on a radiation receiver. The tracking is controlled by means of an auxiliary mirror guiding an auxiliary beam to a target. The position of the point of incidence of the auxiliary beam on the target is detected by a video camera and an image capture system, and said actual position is adjusted to a prescribed target position. It is thus achieved that the main beam is always precisely aimed at the radiation receiver.

主权项

1. A device for guiding solar radiation along a beam path onto a radiation receiver, comprising a single- or multi-stage reflection device having a reflection stage arranged first in the beam path and adapted to track the position of the sun, and comprising a target fixedly connected with the radiation receiver and spatially separated therefrom,
wherein the reflection stage of the reflection device, which is arranged last in the beam path, comprises an auxiliary mirror whose mirror surface forms such an angle with the reflection stage that, when the solar radiation is guided onto the radiation receiver, an auxiliary beam deflected from the solar radiation impinges on the target, and wherein a set position of a point of incidence of the auxiliary beam on the target is predetermined and a control of the reflection device is performed by tracking the actual position of the point of incidence of the auxiliary beam.
