    In order to further optimize the traditional reflective cup for uniform light, anti-glare and other aspects of the problem, a new reflective cup based on Zemax is designed. The simulation results for using the squamous reflective cup show that the maximum light intensity at the front 25 m of the reflective cup is 234 lx, and the light intensity at the center HV point is greater than 0.80 Emax. All indicators meet the requirements of the national standard GB 25991—2010 automotive headlamps with LED sources. The squamous reflective cup can also combine with the micro-lens array. While meeting national standards, the spot energy is more uniform. The central area of light intensity has been further reduced, and the spot edge transition is more smooth. The effect of preventing glare from high beam is better. The system can be widely used in automobile headlamp.
