a dimmer detection module, provided between the power input interface and the power output module, and configured to detect whether a dimmer is connected to the power input interface; and
a first switch device, provided between the power input interface and the power output module, and configured to:
disconnect a circuit connection between the power input interface and the power output module if the dimmer detection module detects that a dimmer is connected to the power input interface, and
conduct the circuit connection between the power input interface and the power output module if the dimmer detection module detects that no dimmer is connected to the power input interface.

2. The under cabinet light interface device as claimed in claim 1 , wherein the power output module comprises:
an alternating current—alternating current conversion module, configured to convert the input alternating current into one or more output alternating currents;
one or more alternating current output interfaces, configured to output the one or more output alternating currents to one or more appliance connected to the one or more alternating current output interfaces;
an alternating current—direct current conversion module, configured to convert the input alternating current into a constant direct current;
