A solar ray collecting device for use in space includes a heat-conductive supporting base plate provided with a large number of adjacent hexagonal recess portions, a large number of optical systems installed on each of the recess portions, a large number of heat-conductive protective bars set up on an upper vertex of a side wall forming the recess portion, and a protective cover for covering a light-receiving surface side of the supporting base plate and having the function of a filter capable of letting visible rays pass through. A pointed end portion of the protective bar is brought into heat-conductive contact with the protective cover. |
