| 摘要 |
The invention relates to an optical system comprising a transparent ball, particularly filled with a transparent liquid. Direct sunlight that is incident on the ball area exposed to the sun is reflected on the opposite, internal face of the hollow ball by means of a rotary mirror in such a way that the focus of the radiation field is reproduced in the center of the hollow ball. Solar converters can thus be statically disposed in the center of the hollow ball and are preferably provided with only one twisting means in order to permanently keep the solar converters in an ideal alignment relative to the focused sunlight. |
