摘要： A smart switch for control of a lighting load from an AC voltage source can replace any switch in a three-way lighting control system. The smart switch can be connected on the line-side or the load-side of a three-way system with a standard three-way switch in the other location. The switch includes two semiconductor switches to control the connected lighting load. The switch preferably includes two sensing circuits for detecting the voltages at two of the load terminals of the switch to determine the state of the connected three-way switch(s), and thus, the load.

摘要： A smart dimmer for control of a lighting load from an AC power source can replace any switch in a three-way or four-way lighting control system. The smart dimmer can be connected on the line-side or the load-side of a three-way system with a standard three-way switch in the other location. According to one embodiment of the present invention, the dimmer includes two triacs to control the intensity of the connected lighting load. The dimmer preferably includes two gate drive circuits coupled to the gates of the triacs for rendering the triacs conductive each half-cycle of the AC power source. The gate drive circuits include sensing circuits for detect whether the gates currents are flowing after the triacs are rendered conductive. A controller is operable to determine the state of the lighting load in response to whether the gate current is flowing or not flowing.
