Abstract
A lens includes a light incident surface, a first light emitting surface, and a second light emitting surface. The first light emitting surface is a convex, curved surface and opposite to the light incident surface. The first light emitting surface includes a first border; the first light emitting surface and the light incident surface cooperatively form a convex lens portion with an optical axis. The second light emitting surface is located at a side of the first light emitting surface adjacent to the first border, and the second light emitting surface is a rough surface for refracting light randomly.

A lens comprising:
- a light incident surface;
- a first light emitting surface, the first light emitting surface being a convex, curved surface and opposite to the light incident surface, the first light emitting surface comprising a first border, the first light emitting surface and the light incident surface cooperatively forming a convex lens portion with an optical axis;
- and
- a second light emitting surface located at a side of the first light emitting surface adjacent to the first border, the second light emitting surface being a rough surface for refracting light randomly.
A light source module comprising:
- a light source;
- and
- a lens, the lens comprising:
- a light incident surface facing the light source;
- a first light emitting surface, the first light emitting surface being a convex, curved surface and opposite to the light incident surface, the first light emitting surface comprising a first border, the first light emitting surface and the light incident surface cooperatively forming a convex lens portion with an optical axis;
