Abstract:
1. An optical lens, comprising: a flange comprising an upper surface and a bottom surface; a protruder that downwardly protrudes with respect to the bottom surface; a first surface that extends from the upper surface of the flange; and a second surface inwardly recessed toward the protruder, wherein the first surface and the second surface meet to form an outer rim of the optical lens, wherein the first surface is sloped with respect to an optical axis, which is a straight line that passes through a center of the protruder and a center of the second surface, and wherein a ratio of a longest straight-line distance between outermost edges of the flange taken across the flange to a shortest straight-line distance from a lowermost point of the protruder to a plane including the outer rim is approximately 0.5 to 5.
