A solar ray collecting device is comprised of a supporting base plate on which a large number of hexagonal recesses are provided and a large number of optical systems are arranged on each of the recesses. Each of the optical systems is made up of a hexagonal focusing lens of a dimension that is approximately the same as the hexagonal recesses and of a heat-cut hexagonal pyramid which extends downward from the light collecting lens as an upper surface of the recess. An optical conductor which is a lightreceiving surface is provided on the focus of the light collecting lens. Furthermore, the upper internal circumferential surface of the side wall forming the recess is so formed that it may be able to move freely on the surface of the hexagonal pyramid. |
