Studium vlivu modulace LED na fotometrické veličiny a homogenitu vyzařování automobilového světla

Abstract

The master thesis is dedicated to optic wireless data networks which use for the transmission the area of visible optical radiation VLC, namely with the possibility of using this technology in communication between vehicles V2V with the use LED broadcasting system in the form of DRL headlight Jaguar XK model 2011. The introductory chapters are about contemporary current foreign studies in V2V communications and it is also about the automobile communication bus systems. In the practical part is set of measurements with the proposed concept of the broadcasting system in the lab dark room at the VSB - Technical University of Ostrava and the research departments of the company Varroc Lighting System Ltd. The analyze the transmission characteristics of LED transmitter through the available devices and related software (LabVIEW 2014, VSG NI PXI-5670, NI PXI VSA-5661) and the influence on optical communication photometric quantities and beam homogeneity of the DRL headlight Jaguar XK according to regulation ECE R 87th.
