A solar ray heat conversion device (20), comprising: a polyhedron lens unit (21) constituted as a regular hexahedron by a bottom surface member (27) as well as a top surface lens (22) and side surface lenses (23-26) formed from an acrylic resin as a square Fresnel lens; and a light reception heat generating part (30), which has an inverted T-shaped cross-section, comprises a bottom member (32) and an erected member (42), and is provided at the center of the bottom surface member (27) on the inside of the polyhedron lens unit (21). It is thereby possible to efficiently collect solar light and reflected light from the solar light, and generate power, from sunrise until sunset using a small and simple configuration without using a mechanism for performing driving so as to track the direction of the sun. |
