| description | An illumination tens includes a light incident surface that defines a cavity and has a flat top surface and lateral flanks, the light incident surface configured to receive light from an underlying light emitting element, a light exiting surface having a central indentation and surrounding toroid, and a bottom surface connecting the light incident surface and the light exiting surface. The lateral flank includes a first region extending from the top surface and a second region extended from the first region, the second region is a curved surface, of which the center of the curvature thereof lies on the illumination lens, an intersection of the second region and a horizontal optical axis forms a first point, and the first point is disposed lower than a second point where the bottom surface and the light exiting surface intersect. |
