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 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. The connecting face is planar. The light emitting face includes a lateral face extending upwardly from an outer periphery of the connecting face and a top face located above the light incident face. The optical lens further includes a plurality of protrusions protruding outwardly from the light emitting face, and a plurality of grooves defining in the connecting face. The protrusions are formed on the lateral face and located adjacent to the connecting face, and the grooves are located adjacent to the lateral face.

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; a connecting face connecting the light incident face and the light emitting face; and a plurality of first protrusions protruding outwardly from the light emitting face, a top end of the first protrusions being lower than a top end of the light incident face; wherein the connecting face is planar, and the light emitting face comprises a lateral face extending upwardly from an outer periphery of the connecting face and a top face located above the light incident face, the top face comprising a planar center facet and a curved facet, the curved facet surrounding and extending outwardly from the center facet; and wherein the first protrusions are formed on the lateral face and located adjacent to the connecting face.
