Abstract
An optic lens assembly includes a platform, and an optic lens including an incident surface and a projection surface on two opposite sides is arranged to an outer side of the platform. The incident surface consists of a plurality of oval-shaped surfaces. A first oval-shaped incident surface and a second oval-shaped incident surface are formed side by side to the incident surface. The two adjacent oval-shaped incident surfaces are concave for receiving an illuminating component. The projection surface also consists of a plurality of oval-shaped surfaces. A first oval-shaped projection surface and a second oval-shaped projection surface are formed side by side to a center area of the projection surface. Two symmetric outer connecting surfaces are formed to two lateral sides of the projection surface. The two adjacent oval-shaped projection surfaces are convex and larger than the incident surface.
