Title:
SOLAR LIGHT CONDENSING DEVICE, CONDENSING DIFFUSING DEVICE AND AUTOMATIC SOLAR LIGHT FOLLOWING SENSOR USED THEREFOR
Document Type and Number:
Japanese Patent JPH05288980
Kind Code:
A
Abstract:
PURPOSE:To utilize solar light instead of an artificial light source and to obtain the extremely drastically saving effect of energy by condensing the solar light by automatically following the movement of the sun and supplying it to an aimed place. CONSTITUTION:The turning mechanism 10 of a fitting table 7 provided on the base part 7a of the table 7 is formed so that a pedestal 10b can be turned around a vertical axis Va by receiving the rotational output of a motor 10a by a gear array, a belt power transmission mechanism or the like. Thus, first and second concave mirrors 1 and 2 being the condensing factors of the solar light can execute a turning action around the axis Va in addition to an oscillating action in a vertical-plane. That means, since the light condensing factors can be turned by 90 deg.-180 deg. in the vertical-plane and turned around the axis Va by 360 deg. with respect to the surface of a ground, they can be always faced to the sun at an installing position from sunrise to sunset. In such a case, a solar light following sensor is used and respective driving motors 9 and 10a are controlled based on the output of the sensor.
