摘要

We propose an innovative vehicle headlight design based on a highly efficient LED light pipe system. In the system, light rays are emitted from multiple high-power LEDs in front of a total internal reflection (TIR) lens. After passing through the TIR lens, the rays are divided into two beams by a prism splitter, and each beam is guided to each headlamp by a light pipe. We propose the system because it uses fewer LEDs but provides enough lumens and reduces the number of TIR lenses required. Detailed analysis of the system is given, and the simulation results show that the headlamp produces a legal Economic Commission for Europe (ECE) low-beam pattern, with a total optical efficiency up to 40.2%, when four LED (Lumileds-K2) sources are used.
