Title:
SOLAR LIGHT TRACKING TYPE REFLECTING MIRROR DEVICE
Document Type and Number:
Japanese Patent JPH02198405
Kind Code:
A
Abstract:
PURPOSE:To eliminate the need of a calculation of an exact position of an installation place and the correction of a tracking device executed by a calendar day, and to track the sun with a simple mechanism by detecting the position of the sun, based on a solar light, and tracking the sun, based thereon. CONSTITUTION:A solar position detecting device 7 detects the position of the sun by an incident angle of a solar light which is made incident on the device, and a result of detection is inputted to a controller 8. The controller 8 controls a first and a second rotary means 6, 3 so that the normal of a reflecting mirror 1 becomes a bisector or an angle made by the solar light which is made incident on the center of the reflecting mirror 1 and the direction to be irradiated with its reflected light, based on the inputted solar position. Also, the direction irradiated with the reflected light is set by a fixing device 9, and in the course of tracking the solar light, the reflected light irradiating direction which is set by a fixing device 4 is not fluctuated. In such a manner, the solar light can be tracked irrespective of longitude and latitude of the installation place and the calendar day, and also, without necessitating the accuracy for adjusting the installation.
