PURPOSE:To simplify the mechanism so that a hot water pipeline and a pump are unrequired by guiding solar light collected to a necessary position as it is by a light guide and converting it to heat. CONSTITUTION:A light collecting plate 1 is provided with a wavelength converter 12 covered in laminated manner on the back surface of a glass plate 11 such as a ZnS:Cu layer, cover glass pieces 15 and 16 provided by forming spaces 13 and 14 through a spacer 19 for preventing stains of the glass plate 11 and the wavelength converter 12, a triangular conical transparent projection 17 for taking out light mounted on the wavelength converter 12, a rotary elliptical mirror 18 provided by setting the light taking out projection as a focal position. A reflection layer to which silver or the like is vapor-deposited between the spacer 19, the glass plate 11 and the wavelength converter 12 is provided, to prevent collected light from dispersing. |
