<P>PROBLEM TO BE SOLVED: To provide a solar light and solar heat utilizing system, in which both solar light and solar heat can be efficiently utilized by a simple structure. <P>SOLUTION: The solar light and solar heat utilizing system 1 includes: a first light condensing part A for collecting solar light via a first light-condensing optical system 2; a heat collecting part B for irradiating an optically-transparent heating medium 3 for heat exchange with the collected solar light to transmit the light, thereby collecting solar heat to the heating medium 3; a second light-condensing part C for collecting the solar light again which is transmitted in the heating medium 3 via a second light-condensing optical system 4; a light guide part D for guiding the re-collected solar light to a lighting spot 6 via a predetermined light guide path 5; and a lighting part E for converting the solar light guided to the lighting spot 6 into diffused light for lighting having uniform illuminance via a diffused optical system 7 to light up the lighting spot 6 with the diffused light for lighting. <P>COPYRIGHT: (C)2013,JPO&INPIT |
