Animal-tests too have additionally revealed the need for care when specifying lighting regimes, and the benefits of optimising spectral emission profiles for specific purposes.It appears possible to develop VLC systems with optimised spectral and frequency emission profiles in order to negate such problems and create more biologically friendly artificial-light than is presently available.

To date the Infrared Data Association (Ir DA) has standardised over 30 specifications that are widely implemented for cordless phones, printers, televisions and other devices.

Its 2008 market-report indicated a prolific increase of Ir DA infrared enabled devices, of which over 1 billion units have been shipped to date, and that demand for such units was likely to increase greatly, particularly with the development of Ir Simple version 1.0 and technological advances used for Giga-IR.

An additional incentive at present is that, whilst free usage of radiowave and microwave wireless communications is restricted by law, VLC technologies do not, as yet, require licenses.

Lighting Types and VLC At present incandescent and fluorescent lamps are the predominant sources of artificial-lighting, with incandescent units being phased out under a strong drive by many governments worldwide to reduce energy wastage.

It has been noted that for RONJA conditions of dense fog or snow can detrimentally effect external transmissions.

Infrared (IR) Communications Infrared devices are often used for data-transmission in devices such as notebook computers, television remote controls and even some newer mobile phones.

VLC data transfer is generally far more secure than conventional wireless local area network (WLAN) links, as it is indicated that only photoreceptors directly within the transmitted cone of light can receive information, thereby making it apparently ‘impervious to interception’.

2010: Demonstration undertaken successfully in Japan showing the combination of VLC with indoor Global Positioning System (GPS).

Their use may help provide both partial and full solutions to a number of technological problems: increasingly limited availability of conventional bandwidths for electronic equipment; possible communications interference with sensitive electrical equipment; data security; and perceived negative health consequences when exposed to raised radiofrequency and microwave levels.

The incorporation of VLC components into everyday technology is being investigated by a number of universities, corporations and organisations worldwide, and has already resulted in the creation of the Japan Electronics and Information Technology Industries Association’s JEITA standards (2007) for a “visible light ID system”, and a Specification Standard in 2008 by the Visible Light Communications Consortium (VLCC) - as a result of its joint cooperative agreement with the Infrared Data Association (Ir DA).
