Abstract
A mechanism for performing a communication using a visible light communication (VLC) protocol. The mechanism proposes to modulate a bus voltage provided to all lighting elements (comprising LED elements) of a lighting unit, so that the magnitude of light emitted by all lighting elements is modulated according to a same modulation scheme. A lighting system having a plurality of lighting elements is also proposed.
