摘要： A lens includes a light incident surface, a first light emitting surface, and a second light emitting surface. The light incident surface is a concave surface and defines a receiving recess. The first light emitting surface is a convex curved surface and is opposite to the light incident surface. The first light emitting surface includes a first border, and 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 and adjacent to the first border. The longer the distance between a point of the second light emitting surface and the optical axis is, the longer the distance between the point and the light incident surface is.
