Design of the Light-Emitting Diode Vehicle Projector Headlamp System without Shield

Abstract:

The light-emitting diode (LED) has been applied extensively to various kinds of applications according to the advantages of its small dimension, low energy consumption and strong reliability. The projector headlamp system proposed in this study was composed of four main critical components including focused LED, asymmetric metal-based plate, freeform surface and condenser lens. It was designed, developed and simulated under low energy consumption to save more energy. Only five 3-Watt focused LEDs without a shield or baffle inside the projector headlamp system was designed to provide the low-beam cutoff in order to meet the requirements of international Economic Commission for Europe (ECE) R112 regulation. Eventually, the prototype of this LED vehicle projector headlamp system was also fabricated to perform the correct light pattern.
