The co-existence of data transmission and lighting inside a common light emitting diode (LED) to complement the radio frequency based wireless communication in satisfying the global socio-economic activities is a low-cost/low-energy proposition termed visible light communications (VLC). It radically turns a passive light source into a dynamic service hub that provides opportunities to improve existing services and introduce new ones.

For this nascent VLC idea to gain traction and realise its huge potential however, vital optimisation approach to mutually accommodate data and illumination on the same LED becomes a necessity. This includes studying, understanding and quantifying the inter-relationship between lighting requirements and data transmission as against the current approach that completely disregards this. To this end, this research investigates the impacts of VLC on light quality of illumination LEDs that are primarily designed for lighting/display. The findings from this work will provide the required approach for optimising VLC and safeguard the LED's reliability, durability and emitted light quality
