In this embodiment, the angle between the light incident side 61 and the light exit side 62 is less than 90 degrees.

Referring to FIG. 4A , in this embodiment, the light incident side 61 and the light exit side 62 jointly define a space 64 . The light output side 62 is suitable for guiding the light refracted by the light input side 61 and the space 64 , so that the light is emitted to the surface of the lens 211 in a direction approximately perpendicular to the surface of the lens 211 . More specifically, the optical component 215 is a hollow structure, including two thin plates forming an angle and an arc-shaped thin plate.
