Abstract
Abstract An upper component lens which receives and refracts a circular whole incipient beam, forming a convergent conical beam; a first middle component lens which refracts the convergent conical beam, forming an annular beam; a second middle component lens which refracts the annular beam, forming a convergent conical beam; and a lower component lens which refracts the convergent conical beam, forming a concentrated whole beam which is emitted parallel to the vertical optic axis of the concentrator.

Claim 1
Independent Claim
197 words
A conical beam concentrator 4RT:C comprising in general four conical component lenses which receive a circular whole incipient beam of direct sunlight and emit a circular whole concentrated beam, and comprising in particular; an upper component lens RT (1) having a planar section (7) which receives and transmits a circular whole incipient beam (6) of direct sunlight and having a convex conical section (8) which refracts incipient beam (6), forming a convergent conical beam (9), a first middle component lens RT (2) having a concave conical switch (10) which transmits convergent conical beam (9) and having a convex conical section (11) which refracts convergent conical beam (9), forming annular beam (12), a second middle component lens RT (3) having a planar section (13) which transmits annular beam (12) and having a convex conical section (14) which refracts annular beam (12), forming a convergent conical beam (15), and a lower component lens RT (4) having a convex conical section (16) which transmits convergent conical beam (15) and having a concave conical section (17) which refracts convergent conical beam (15), forming a concentrated circular whole beam (18) which is emitted parallel to the vertical optic axis of the lenses.
