Abstract
A lens includes a light incident face, a light exit face opposite to the light incident face and a plurality of annular stepwise portions formed on the light exit face. The stepwise portions are located at or near a periphery of the light exit face and each stepwise portion has an annular flat surface. A plurality of micro patterns are arranged on the flat surface of one stepwise portion to scatter light exiting from the periphery of the light exit face. A light source module incorporating the lens is also provided. The light source module includes an LED light source. Light from the LED light source enters the lens from the light incident face and leaves the lens from the light exit face after the light is divergently refracted by the lens.
