Abstract: The present invention involves utilizing AC power lines adapted for connection to an AC power source and a signal line to perform baseband signal transmission and communication. According to the invention, a threshold voltage is provided as a comparison reference for an AC input voltage to determine whether the communication is permitted. If the AC input voltage is greater than the threshold voltage, the communication is permitted. On the contrary, if the AC input voltage is smaller than the threshold voltage, the communication is not permitted. By virtue of the invention, the initiation time and the termination time of the baseband signal communication for each load tend to be substantially identical. Reliability is thus increased and noise interference problem is not created.

Abstract: The invention relates to a lighting system of alternate current light-emitting diodes (AC-LEDs). The system includes a first, a second and a third AC-LED modules, each two of them being electrically connected in parallel to one another and further electrically connected to a first, a second or a third phase voltage input terminal. The respective AC-LED modules include a first and a second LED modules. The system is further provided with rectifier circuits and multi-stage driver modules. The invention involves driving the AC-LED modules to emit light in an alternate manner using a three-phase AC power source, thereby reducing the flicker index, and further driving the first and the second LED modules to light up in different alternating orders, thereby rendering the light emission of the AC-LED lighting system substantially constant in terms of power and brightness.
