OPTICAL LENS AND LIGHT SOURCE MODULE HAVING THE SAME

摘要

A light source module includes a light source and an optical lens facing the light source. The optical lens includes a light incident surface facing the light source, and a light emitting face opposite to the light incident face. The light emitted from the light source is entered into the optical lens from the light incident face, and exited from the light emitting face. A refractive index of the optical lens gradually decreases along a direction from the light incident face to the light emitting face of the optical lens.

主权项

1. An optical lens for adjusting light emitted from a light source, comprising:
a light incident face facing the light source; a light emitting face opposite to the light incident face; and a connecting face connecting the light incident face and the light emitting face, and the light emitting face comprising a first curved face and a second curved face surrounding and extending outwardly from the first curved face; wherein an outer periphery of the second curved face of the light emitting face correspondingly meets an outer periphery of the connecting face.
