SUNSHINE COLLECTION SYSTEM

Japanese Patent JPH01229216

A

PURPOSE:To collect the sunshine with high accuracy by providing two rotary shafts for sunshine tracking to a light gathering part where the focuses of a light collection part and a reflection part are made incident with each other, and using one of them as the rotary shaft of the light gathering part and the other one as the rotary shaft of the integrated body of the light gathering part and reflection part. CONSTITUTION:Reflection mirrors 1 and 2 which constitute a light collection part has their focus coincident with each other and the reflection mirror 1 is rotated by a driving motor 4 around a rotary shaft 5 in an altitude direction. Further, the mirror can be rotated in an azimuth direction by a column 3 which has its center of rotation on a perpendicular containing the focus of the reflection mirror. The reflection mirror 2 is supported on a column 6, which is not coupled with the driving motor 4 and serves as a nonrotary shaft, so the reflection mirror 2 rotates only in the azimuth angle direction together with the reflection mirror 1 in one body as the column 3 rotates. The sunshine which is collected by the reflection mirror 1 is reflected by the reflection mirror 2 irrelevantly to the position of the reflection mirror 1 which tracks the sun and travels downward perpendicularly through the window 7 of the column 3.
