Apparatus for pursuing the sun to secure a constant sunlight energy source comprising a rotary shaft equipped with a light receiver; a thermo-deforming plate to force an area in proximity to its light collecting portion with a raised temperature to become the lowest portion of curved concave; a convex lens placed over the thremo-deforming plate; and a follower rod connected to the rotary shaft in a manner to be able to swivel in the axial direction of the rotary shaft; said follower rod being equipped with a rolling piece in its lower end, so that the thermo-deforming plate underneath and transverse to the rotary shaft in a position whereupon the rolling piece of the follower rod is placed on the thermo-deforming plate in a manner such that the follower rod is forcibly pressed down to place the rolling piece constantly against the bottom of the curved concave of the thermo-deforming plate formed by its thermal deformation. Sunlight passing through the convex lens is collected by the thermo-deforming plate and its light collecting portion deforms thermally leading to the parabolic deformation of the whole thermo-deforming plate. As a result, the rolling piece is rollingly moved by means of the follower rod towards the lowest portion of the thermo-deforming plate, and the light receiver rotationally pursues the sun by the rotation of the rotary shaft connected to the follower rod. |
