Patent ID: 8007139

Claim:
An optical illumination module, the characterized in that: a fixed light source disposed to a coordinate origin; and a plano-convex lens with rotational symmetrical aspheric feature in which coordinates (X, Y) of points at a convex curve are (9, 11.75), (8, 13.15), (6, 15.25), (4, 16.65), (2, 17.45), (0, 17.65), (−2, 17.45), (−4, 16.65), (−6, 15.25), (−8, 13.15), (−9, 11.75) respectively, and a curve variation of the convex curve composed of the coordinates is within ±1 millimeter, and a light beam generated by the fixed light source is refracted as a parallel light beam from an convex end.
