  • Patent number: 11536442
    Abstract: Disclosed is a power strip with a night light function. An LED light group is arranged based on a traditional power strip, powered by a power supply unit led out between a live wire and a neutral wire in a plug/socket, and controlled by a control unit for work. As arranged on the plug and/or socket, the LED light group can be controlled to be turned on when light is dark. The power strip is convenient to find, plug and use, and can serve as a night light for lighting at night. The control unit respectively has automatic, normally open and normally closed control modes which can be switched by a user toggling a mode switching switch as required. The design of the power strip facilitates use in dark environments and adds a new function, thereby having the advantages of simple structure, reasonable design, convenient use and diversified functions.
