Abstract (en)
An optical assembly (1) of alert light has two nonlinear optical halves (10A, 10B) obtained by symmetrically dividing the optical assembly (1) along an optical reference plane. Each optical half (10A, 10B) has a base (11), which takes a nonlinear and curved form with one side thereof corresponding to the optical reference plane and having a junction surface (112). A light entrance portion (12) and a light exit portion (13) are on two opposite sides of the optical reference plane. The two optical halves (10A, 10B) are assembled to form the nonlinear optical assembly (1) with the junction surfaces (112) therebetween. The nonlinear optical assembly (1) reduces molding and manufacturing requirements. Given the light exit portions (13) of the optical halves (10A, 10B), each light entrance portion (12) corresponds to multiple bulged portions for the nonlinear optical assembly (1) to provide uniform lighting effect.
