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 top face of the light emitting face comprises a center curved facet and a periphery curved facet surrounding and extending outwardly from the center curved facet. The light incident face is a discontinuous face and includes a plurality of curved facets.

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; 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; wherein the top face of the light emitting face comprises a center curved facet and a periphery curved facet surrounding and extending outwardly from the center curved facet; wherein the light incident face is a discontinuous face and includes a plurality of curved facets; and wherein a width of each curved facet gradually decreases along a bottom-to-top direction of the optical lens.
