[0002] With the continuous advancement of LED technology, LED linear light strips are widely used in customized panel cabinets such as wardrobes, bathroom cabinets, hallway cabinets, and cupboards. LED linear light strips can significantly improve the convenience of cabinet home use by lighting the interior of the cabinet.

[0003] like Figure 1 As shown, the plug of the power cord of the existing LED linear light bar is directly inserted into the lamp. When the LED linear light bar is repaired or replaced, the power cord hidden in the cabinet plate will be pulled out when the lamp is disassembled. Since the LED linear light bar is installed close to the cabinet, the lamp and the power cord are easy to damage the surface of the cabinet during the disassembly process, and the power cord is difficult to hide in the cabinet plate again during the installation process. In addition, the plug of the power cord of the existing LED linear light bar realizes the conductive function by electrically contacting the lamp through a conductive spring.
