A solar concentrator assembly includes a light splitting element, a light converging element, an optical fiber unit and a photoelectric unit. The apparatus in this invention is characterized by a platform, a pressing unit with at least one press head, and at least one laser projector for projecting a laser beam to form a light area. Treated bulk materials are anisotropic, with enhanced strength oriented along the axial direction. The oil pump pumps up an oil from an oil reservoir via an oil path to supply the pumped-up oil to another oil path. Resonating frequencies of the element can be arranged by shaping the element, and by means of discrete components.
