ABSTRACT:
The present invention relates to light transmitting panels mainly applied to lighting windows in openings of general buildings and lighting quantity or range adjusting methods for interiors of general buildings using any of the light transmitting panel's. One of the light transmitting panels consists of two transmitting plates and plural refractive columns located in parallel to each other between the two plates, and another of the light transmitting panels consists of base faces with reflecting zones parallel to each other formed on them. Furthermore, optional sunlight patterns S1, S2 and S3 incident from the sun located differently in altitude or azimuth with respective incident angles of .alpha.,.beta. and .gamma. in reference to altitude or azimuth satisfying the relation of .alpha.<.beta.<.gamma. are selected as the sunlight patterns used for adjusting the lighting quantity or range by devising the structure of the light transmitting panel used, in order that the difference in the quantity of heat in the interior caused by respective seasons and respective time zones due to the annual or daily motion of the sun may be adjusted by using the difference of the sun in altitude or azimuth, for effective utilization of heat.
