The optical body comprises a reflecting surface and an injection mark, wherein the optical path turns at the reflecting surface, the optical path does not pass through the injection mark, and the number of reflecting surfaces can be multiple. The sheet-like shading element is closer to the optical path than the injection mark, and the sheet-like shading element comprises a first surface, a second surface, and a first shading structure, wherein the second surface is arranged opposite to the first surface, and the second surface is farther away from the reflecting surface than the first surface. The first shading structure comprises a first edge, wherein the first edge connects the first surface and the second surface, the first edge faces the optical path, and is arranged around the optical path, and the optical body is in physical contact with the first edge, the first surface, and the second surface.
[0178] By placing the sheet-shaped shading element closer to the light path than the injection mark, glare caused by light passing through the plastic injection mark can be avoided, thereby ensuring the optical quality, wherein the sheet-shaped shading element can be further formed into the above structure by sheet metal, stamping, laser, etching and other processes, but is not limited thereto. Furthermore, by physically contacting the optical body with the first edge, an internal shading structure is formed, and simultaneously physically contacting the first surface and the second surface, thereby ensuring the bonding of the sheet-shaped shading element with the optical body.

The injection mark is the trace of the flow of the optical body in the process, which forms a specific spatial geometric feature due to the mold and the post-processing process, and the injection mark can also be called the material flow mark, which is not limited by the customary terminology. The above-mentioned spatial geometric feature can be the shape of the injection flow channel, the shape of the knife and scissors, and the shape of the overflow, but is not limited to this. The first edge of the first light-shielding structure can close or open the surrounding light path.
[0180] The first edge may include a plurality of shading petals, wherein the number of the shading petals of the first edge may be between 14 and 250, and the shading petals are arranged adjacent to each other to ensure the effectiveness of the shading structure.
