For the requirement of high efficiency light emitting diode (LED) luminaries and the characteristics of automotive headlamp exit beam,based on non-imaging optical theory,a theory model for new type LED parabolic reflector optimal design is established to maximize the utilization of light energy of the reflection cup and to realize the asymmetric light intensity distribution of the headlamp exit beam. An optical system of new type reflective LED automotive headlamp is designed. By TracePro simulation it shows that the geometry collection rate of reflector reaches up to 96% without considering the loss. In the screen that places at 25 m the width of the field of view is greater than 10 m. The emitting light distribution of low-beam has a distinct cut-off line and the light distribution of high and low beam are both satisfying the national standard,with the structure size of entire lamp only 160 mm×80 mm×25 mm.
