ABSTRACT:
With the increasing popularity of solid sate lighting
devices, Visible Light Communication (VLC) is globally recognized as an
advanced and promising technology to realize short-range, high speed as well as
large capacity wireless data transmission. In this paper, we propose a
prototype of real-time audio and video broadcast system using inexpensive
commercially available light emitting diode (LED) lamps. Experimental results
show that real-time high quality audio and video with the maximum distance of 3
m can be achieved through proper layout of LED sources and improvement of
concentration effects. Lighting model within room environment is designed and
simulated which indicates close relationship between layout of light sources
and distribution of illuminance.
