We propose a reflective optics design for an LED motorbike high beam lamp.We set the measuring screen as an elliptical zone and\ndivide it into many small lattices and divide the spatial angle of the LED source into many parts and make relationships between\nthem. According to the conservation law of energy and the Snell�s law, the reflector is generated by freeform optics design method.\nThen the optical system is simulated by Monte Carlo method using ASAP software. Light pattern of simulation could meet the\nstandard.The high beam headlamp is finally fabricated and assembled into a physical object. Experiment results can fully comply\nwith United Nations Economic Commission for Europe (ECE) vehicle regulations R113 revision 2 (Class C).
