Abstract
A lens assembly with a high uniform rectangular focused halo comprises: a first lens and an adjacent second lens. The first lens includes a first incident surface, a first non-spherical surface, and a first convex array emitting surface. The first incident surface contains a light source focus, and the first convex array emitting surface consists of multiple non-spherical convex arrays having rectangular openings. The second lens includes a second concave array incident surface and a second non-spherical surface emitting surface. The second concave array incident surface consists of multiple non-spherical concave arrays having rectangular openings corresponding to the first convex array emitting surface. The lens assembly provided by the present invention allows light to pass through only one total internal reflection lens and one flat convex lens so that the energy can be focused, while maintains an ultra-high optical efficiency.
