Reliability study on SSL under high speed switching condition

Abstract

Visual Light Communication (VLC) is a system that uses light wavelength that is not

injurious to the eye for communication purposes. This system provides a solution to some

technological problems like increasingly limited availability of conventional bandwidths for

electronic equipment.Recent development in Solid-state lighting (SSL) allows it to be highly efficient, longer life

time and versatile. Having these advantages made SSL to be highly acceptable by the public

and is slowly replacing the conventional fluorescent lamp. The improvement and

acceptability of the solid-state lighting allows a great advancement in the development of

VLC.However, the focus of the development of SSL are for lighting purposes and not VLC

system. This report will investigate the degradation behaviour of SSL under various stress

condition like temperature, frequency, Modulation Index and draft out a operating guideline

for practical implementation of SSL on VLC system.
