Mirror arrangement for automatic following of moving light source in solar plant

摘要

The mirror arrangement includes a rotating arrangement of at least two mirrors (1, 2), whereby the first mirror (1) is arranged revolving with respect to the next mirror (2), around the axis (4) of a ray of light reflected by the first mirror. A control unit connected with a sensor unit (6), controls at least two positioning motors (7, 8) for turning the arrangement and the first mirror. The mirror arrangement includes a rotating arrangement of at least two mirrors (1, 2) or similar, whereby the first mirror (1), as seen in direction (A) of the incidenting light, is arranged revolving with respect to the second and/or the next mirror (2) around the axis (4) of a ray of light reflected by the first mirror. An optic sensor unit (6) is oriented in direction of the light source, following the first mirror. A control unit is connected with the sensor unit (6), and controls at least two positioning motors (7, 8) for turning the mirror arrangement and the first mirror, whereby the arrangement of mirrors is arranged revolving around an axis (5) of the ray of light reflected by the second mirror in direction (B) of a determined target area.
