The central portion has a first and a second optical surfaces. The surrounding portion surrounds the central portion and has an inner refraction wall and an outer refraction wall. The outer refraction wall includes a first and a second outer surfaces. A distance between the symmetry axis and a junction of the inner refraction wall and the first optical surface is a first radius R1. A distance between the symmetry axis and a junction of the first outer surface and the second optical surface is a second radius R2. A distance between the symmetry axis and a junction of the second outer surface and the first outer surface is a third radius R3. The third radius R3 is greater than the second radius R2, and the second radius R2 is greater than or equal to the first radius R1.
