| Abstract: | In this paper, a kind of car Head lamp integrating freeform reflectors for bright white LED is presented. Complying with the National Standard GB25991-2010 and considering light source properties known, at first, the freeform reflector is designed with RefCAD, and then several reflector models are integrated into a car head lamp model. The illumination values of the test points and regions are simulated with Tracepro. The simulation results show that it meets the requirement of low beam-GB. This design takes the advantage of LED, increases the utilization of optical energy, and greatly optimizes and saves the design space. |
