Abstract: A lens system includes a TIR (Total Internal Reflection) lens and a diffuser. The lens has an optical body member including an upper end, a lower end opposite the upper end, and an outer surface. The outer surface is shaped to provide total internal reflection for light from a light source. An upper surface extends in a series of steps from the upper end to a first interior portion of the optical body member. A substantially cylindrical cavity extends from the lower end to a second interior portion of the optical body member. A middle portion separates the first and second interior portions and has a flat upper surface and a curved lower surface. The diffuser has a curved shell configured for disposing over a light source and configured to fit inside the cylindrical cavity of the optical body member, the diffuser having a circular rim fused to the lower end of the optical body member.
