Disclosed is a lampwick plug assembly, including an LED lampwick, a plug and a plug body; the plug body is plugged in the inner side of a through hole and is configured to fix the LED lampwick on the plug, the LED lampwick includes LED filament, and the LED filament is packaged with a conductive wire matching the resistance value. The lampwick plug assembly provided in the present disclosure can simplify the plug structure and reduces the production cost through a simple plug and plug body structure. The LED lampwick is fixed on the plug through the plug body, which facilitates the installation and mass production. In the structure, the resistor is packaged inside the LED filament, eliminating relevant structure and process of fixing the resistor, such that the structure can be widely used in the manufacturing process of existing LED bulbs.
