Abstract:
1. A lighting system comprising: a master controller comprising a microcontroller, and a power line polarity switching unit configured to control a level of direct current from a direct current source to one or more slave control units via a first power line of a direct current (DC) circuit having a voltage polarity and a second power line of the DC circuit having a voltage polarity opposite the polarity of the first power line, the master controller configured to communicate with the one or more slave control units via switching the voltage polarities of the first power line and the second power line as a unidirectional communication system, wherein the master controller communicates to the one or more slave control units an intended action that is to be executed by the one or more slave control units and wherein the line polarity switching unit of the master control comprises a single H-bridge circuit in order for the master control to communicate to a plurality of slave control units.
