Claim:
1. A nonlinear optical assembly of an alert light, comprising two nonlinear optical halves obtained by symmetrically dividing the nonlinear optical assembly along an optical reference plane, wherein each nonlinear optical half has: a base integrally formed and taking a nonlinear and curved form, wherein one side of the base corresponding to the optical reference plane has a junction surface, and the two nonlinear optical halves are assembled to form the nonlinear optical assembly with the junction surfaces of the two nonlinear optical halves attached to each other; a light entrance portion formed on one side of the base and adjoining the junction surface; and a light exit portion formed on another side of the base, and adjoining the junction surface, and being opposite to the light entrance portion; wherein the base has:
