<p>The system has a set of illuminating units e.g. Christmas-tree lights, connected to wireless receiver circuits. The receiver circuit running freely in an asynchronous mode with respect to the other circuit is switched on to an energy-saving stand-by mode based on its duty cycle. A transmitter circuit provides switching information/stand-by information/synchronizing information to the receiver circuit in the stand-by mode.</p> |
