In order to design a reasonable projector-type headlamp to obtain better lighting quality and less dazzling effects for coming vehicles and pedestrians,the successive approximation method is adopted for solving the binary high ordered generatrix equation of the aspheric lens and establishing the mathematical model of the aspheric lens.The axial length gradient method is used to realize the transition from the horizontal to the vertical plane for the VariRot Ellipsoid reflector,and to establish the equation of VariRot Ellipsoid reflector,thus the aspheric lens and the reflex mirror of the projector-type headlamp are designed.Based on this,the optical model of the projector-type headlamp is established with the software—lucidshape,meanwhile the simulating experiments are carried out.The experiment results indicate that design of the aspheric lens with the successive approximation method and the VariRot Ellipsoid reflector with the axial length gradient method are feasible,and the designed projector-type headlamp meets the GB4599-2007 and ECE R112 regulations.
