Abstract
Abstract A conical beam concentrator comprising; (a) an upper component lens with a convex conical section (face) which receives a convergent conical incipient beam of diffused sunlight and transmits the beam through the lens to a convex conical section which refracts the beam inward, forming a convergent conical concentrated beam, (b) a lower component lens with a convex conical section which transmits the beam through the lens to a convex conical reflective section which reflects the beam downward to a concave conical section which refracts the beam a second time, forming a concentrated whole beam which is emitted parallel to the vertical optic axis of the concentrator.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
150 words
A conical beam concentrator comprising in general two component lenses which receive a convergent conical incipient beam of diffused sunlight and emit a concentrated whole beam parallel to the optic axis of the lenses, and comprising in particular; an upper component lens RT (1) having a convex conical section (5) which receives and transmits a convergent conical incipient beam (4) of diffused sunlight, and having a convex conical section (6) which refracts and emits incipient beam (4), forming convergent conical concentrated beam (7), and a lower component lens RLT (2) having a convex conical section (8) which transmits concentrated beam (7), having a convex conical reflective section (9) which reflects concentrated beam (7), forming convergent conical beam (10), and having a concave conical section (11) which refracts and emits convergent conical beam (10), forming concentrated whole beam (12) which is emitted parallel to the vertical optic axis of the lenses.
Claim 2
Dependent Claim
150 words
A conical beam concentrator comprising in general two component lenses which receive a convergent conical incipient beam of diffused sunlight and emit a concentrated whole beam parallel to the optic axis of the lenses, and comprising in particular; an upper component lens RT (1) having a convex conical section (5) which receives and transmits a convergent conical incipient beam (4) of diffused sunlight, and having a convex conical section (6) which refracts and emits incipient beam (4), forming convergent conical concentrated beam (7), and a lower component lens RLT (2) having a convex conical section (8) which transmits concentrated beam (7), having a convex conical reflective section (9) which reflects concentrated beam (7), forming convergent conical beam (10), and having a concave conical section (11) which refracts and emits convergent conical beam (10), forming concentrated whole beam (12) which is emitted parallel to the vertical optic axis of the lenses.
