Abstract:
1. A LED system for illumination and data transmission, said LED system comprising: a LED driver operable to provide a control signal and a plurality of LED currents; an electronic switch in electrical communication with said LED driver to receive the control signal; an illumination unit including a plurality of LED light sources, wherein a first at least one LED light source is in electrical communication with said LED driver to facilitate a flow of a first at least one LED current from said LED driver through said first at least one LED light source whereby said first at least one LED light source emits a first light output in response to the flow of the first at least one LED current through said first at least one LED light source, wherein a second at least one LED light source is in electrical communication with said electronic switch to facilitate a flow of a second at least one LED current from said LED driver through said second at least one LED light source whereby said second at least one LED light source emits a second light output in response to the flow of the second at least one LED current through said second at least one LED light source, and wherein said electronic switch is operable to one of facilitate or impede the flow of the second at least one LED current from said LED driver through said electronic switch and said second at least one LED light source as a function of the control signal.
