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.
