METHOD FOR CONTINUOUSLY CONVERGING AND FOLLOWING UP SUNSHINE AND DELIVERING SUNSHINE OF HIGH DENSITY TO SUNSHINE TRANSPORT PIPE LIGHT GUIDE-IN PART

摘要

PROBLEM TO BE SOLVED: To deliver the intense sunshine which is suitable for practical use to a place that the sunshine does not reach by a thin sunshine transport pipe which is small in sectional area by guiding the intense sunshine of high density, obtained by converging the sunshine, in the sunshine transport pipe from the sunshine transport pipe light guide-in part in combination with the sunshine transport pipe. ;SOLUTION: The sunshine guide-in parts 4 of sunshine transport pipes are fixed at three intersections 6 of the maximum point angle 1 of the sun movement in the day of one year, the sun altitude angle 2 of the vernal equinox and autumnal equinox points, and the focus 3 of a sunshine condenser lens. Assuming that the sunshine guide-in parts 4 of the sunshine transport pipes placed at the three intersections 6 are the reference points of the angles, the focus 3 of the sunshine condenser lens is always at the sunshine guide-in part 4 of the sunshine transport pipe when the sunshine condenser lens 5 is adjusted to an angle a half as large as the angle difference between the reference points and sun position, so that the converged intense light beam is guided in the sunshine transport pipe through the sunshine transport pipe guide-in part.;COPYRIGHT: (C)1997,JPO
