PURPOSE:To collect solar light efficiently even on a cloudy day, not to mention a fine day, by arranging a photodetector which collects light in any direction at the focus position of a parabolic reflecting mirror. CONSTITUTION:The photodetector 1 guides solar light to a photoconductor 11, in a direction SL1 and solar light to a photoconductor 12 in a direction SL2 through lenses L1 and L2 and light guide-in parts 11' and 12' and those solar light beams are put together by a connector 2 and guided to a desired place through a single photoconductor cable 3. The photodetectors 1 are arranged at the focus position of the parabolic reflecting mirror 4. Consequently, solar light is collected efficiently even on a cloudy day, not to mention a fine day. |
