Abstract

Disclosed is a light diffusing lens having a pointing angle distribution focused toward a lateral direction. The disclosed light diffusing lens includes a light entrance portion having a shape which is concave inward from the lower portion of the light diffusing lens, a reflection portion having a shape which is concave inward from the upper portion of the light diffusing lens, and a light exit portion defined by the outer surface of the light diffusing lens. The light entrance portion has a first convex surface which is convex in an optical axial direction defined by a straight line passing through the center of the light diffusing lens as it goes toward the inside of the light diffusing lens.
