The light guiding portion 11 is an annular groove structure, the groove 112 includes an annular bottom wall 112a, and a first side wall 112b and a second side wall 112c connected with the bottom wall 112a, the first side wall 112b is connected with one side of the bottom wall 112a close to the annular center, and the second side wall 112c is connected with one side of the bottom wall 112a far from the annular center; the angle α between the first side wall 112b and the bottom wall 112a is smaller than the angle β between the second side wall 112c and the bottom wall 112a.

In the present embodiment, the included angle α between the first side wall 112b and the bottom wall 112a is 115°±2°; the angle β between the second side wall 112c and the bottom wall 112a is 145°±2°. The first and second sidewalls 112b and 112c are provided with reflective materials for reflecting the illumination light L1 to modulate a beam section of the illumination light L1 into a ring shape.
