PROBLEM TO BE SOLVED: To permit the light reception of a wide area with a low posture by a method wherein the thickness of a heat collector in a sunward direction is thinned and high temperature heat collection is facilitated while reducing the number of driving mechanisms with respect to the area of light reception. SOLUTION: A first parabolic mirror 40a or a plane mirror, a second parabolic mirror 52 and a light/heat converting block 61 are mounted in a box body surrounded by a flat glass plate 36 or a Fresnel lens and plates 31, 33 to turn and reflect the light of incidence in the box body whereby solar beams are collected and projected on a light/heat converting conical surface 63 by the box body with a thin thickness through a long distance light path. A flow passage 69 is formed in the block 61 and heat exchanging fluid is conducted to flow through the same and collect heat. Dried air or inert gas is sealed in the box body through a valve device. Heat collectors of a total number of 64 sets are supported by supporting device group of 4×4=16 sets, arrayed in matrix array and supporting respective 4 pieces of AZ shafts by each EL shafts. One set of the driving machine drives 4 sets of supporting devices.
