Abstract

A plug-in multifunctional LED power system includes a power supply module, at least one output terminal, a switch module, a trigger conversion module, a compatible circuit module, and a replaceable control chip module. The trigger conversion module includes a first, second and third resistors connected in series from a high level output terminal to a ground. The switch module includes an N-type MOS transistor. The compatible circuit module is used for controlling on-off of the switching module by different control chip modules. The control chip module processes the input signal of the signal access unit and outputs a control signal for controlling the on/off of the switching unit so as to control the operating state of a LED lamp. The plug-in multi-functional LED power supply system can solve the increase of the production costs and the inconvenience for user installation caused by more existing power supply types and different models.
