Study of LED Modulation Effect on the Photometric Quantities and Beam Homogeneity of Public Lighting

Popis výsledku v původním jazyce

This paper discusses the implementation of a light emitting diode based visible light communication system for Visible Light Communications (VLC) in road safety applications. Visible Light Communication (VLC) represents a progressively developing communications technology. This technology uses optical radiation in the visible range in order to illuminate a given area also for the communication purposes (download). One of the conditions of using the technology is the construction of a VLC modulator. The use of the technology Bias-T proves to be a highly efficient concept of the VLC modulator. The article deals with the design of a high power broadband Bias-T allowing the use of the VLC technology The designed Bias-T was created and its functionality verified using a network analyser and the software-defined radio. Other problem is correct design of modulation circuits so that final public lightning using optical communication meets standard requirements on Photometric Quantities and Beam Homogeneity. Authors of this article performed research on visible light communication possibilities of public lightning in terms of modulation circuits (M-PSK, M-QAM, OFDM) implementation into the lamp concepts and final fulfilment of mandatory standards on Photometric Quantities and Beam Homogeneity.
