Abstract
A lens includes a convex surface formed in an outer surface thereof facing away from a light source to uniformly distribute light emitted from the light source; a concave surface concaved inward from an inner region of the convex surface, around an optical axis; and a convex portion convexed outward from a central region of the concave surface, which the optical axis intersects, in order to enhance quantity of light around the optical axis. The lens refracts light beams falling onto the respective areas thereof at different angles, thereby producing a uniform light distribution within a specific lighting range, but does not create a dark area around an optical axis.
