Abstract

This paper proposes a low-beam system for an LED-based headlamp architecture, which is composed of an elliptical reflector, a baffle, and a faceted reflector. Using a single device with high brightness LED of merely 6.00 W, two devices total 12.00 W. With a low beam 55 W traditional halogen light source compared to 78.18% energy savings, the specified illumination requirements for the headlamp low beam can be achieved, according to the ECE regulation “Addendum 111: Regulation No. 112 Revision 2.” As we have expected, on the test screen at a distance of 25 m, the simulation results as well as the testing results for the prototype can reach the illuminance distribution requirements, including all specified regions and key points. Moreover, this faceted low beam system enjoys the features of high compactness, high energy efficiency, and feasibility of manufacturing.
