Abstract- Solid-state lighting is a rapidly developing field.
White-light and other visible LEOs are becoming more efficient,
have high reliability and can be incorporated into many lighting
applications. Recent examples include car head-lights based on
white LEOs, and LED illumination as an architectural feature.
The prediction that general illumination will use white LEOs in
the future has been made, due to the increased energy efficiency
that such an approach may have. Such sources can also be
modulated at high-speed, offering the possibility of using
sources for simultaneous illumination and data communications.
Such Visible Light Communications (VLC) was pioneered in
Japan, and there is now growing interest worldwide, including
within bodies such as the ,risible Light Communications
Consortium ("LCC) and the Wireless World Research Forum
(WWRF). |
