In some embodiments, the lens body 10 generates an imaging effect in a three-dimensional space, so that high reflection and high convergence are better achieved, and the imaging effect is ensured.
In some embodiments, the integral coating layer covers the concave surface and/or the convex surface of the lens body 10, that is, the integral coating layer may cover only the concave surface of the lens body 10, only the convex surface of the lens body 10, or both the concave surface of the lens body 10 and the convex surface of the lens body 10, so that the lens can play a role of ring focusing and reflecting, and finally, the effect of scattering strong light can be achieved.
