Abstract

We herein study the more advanced form of the Light Emitting Diode (LED) light source used as an automotive headlight. We have attempted to convert the existing system configuration paradigm comprising a fixed simple light source and a traditional illumination optical system that can convert or manipulate, to a system comprising a combination of variously switched light sources and a fixed illumination optical system. To achieve the above-mentioned objectives, we studied the internationally recognized North American Standard Light Distribution Regulations [specifically, UB1, LB1M, and LB1V of Type F], and the European Standard Light Distribution Regulations [specifically Class B of normal mode, and Class V, Class E and Class W of adaptive front-lighting systems (AFS)]. The results show that the customized optical system paradigm with an existing fixed light source can be converted into a fixed optical system paradigm with a convertible light source.
