Abstract
A lens includes a light incident face, a light exit face opposite to the light incident face and a plurality of micro dot patterns formed on the light exit face. The light incident face is a concave face and the light exit face is a convex face. The plurality of micro dot patterns are positioned at a central portion of the light exit face. A light source module incorporating the lens is also provided. The light source module includes a light emitting diode emitting light into the lens through the light incident face. The micro dot patterns direct the light from the light emitting diode and through the central portion of the light exit face toward a peripherial side of the lens.
