The Application of Integral Source Model in The Design of Freeform Optics for Several Multidirectional Light Sources

Abstract

One of the features of an intelligent transport system is the formation of communication channels between vehicles. Vehicle-to-vehicle communication will help reduce the number of road accidents. Li-Fi technology is considered as a method for communication. Li-Fi uses visible light for data transmission. A single source of radiation may not be sufficient to provide a certain signal level at the receiver, so multiple sources must be used. Also, signal transmission should be in all directions in the horizontal plane. The study addresses the problem of designing optical systems of circular radiation with several multidirectional sources. It proposes the modification of the ray mapping method for the task of designing optical elements for the Li-Fi wireless communication technology between vehicles. Also, it describes the algorithm for calculating optical systems of circular radiation for a signal source and signal receiver. Finally, the results of calculating and virtual prototyping of devices designed by the proposed method.
