[0002] Currently, cabinet lighting is mainly used for localized lighting inside cabinets, such as above or below a wardrobe in a room. Because the light inside the cabinet may be blocked by the cabinet panels, resulting in insufficient light, cabinet lighting can make up for this deficiency. For example, in the kitchen, the wall cabinets are installed above the kitchen, and the kitchen lights shine down from above, making the cabinets above or in corners insufficiently lit.
[0003] By embedding conductive rails inside the cabinet and embedding multiple power supply terminals vertically on one side of the cabinet wall where the conductive rails are embedded, and all power supply terminals are electrically connected to the conductive rails, the cabinet lights are embedded on the shelf, and power take-off terminals are set on the cabinet lights. The power take-off terminals and power supply terminals work together to provide power to the light panel.
[0004] Currently, the cabinet lights use welding or wires to connect the light panel and the power supply terminal, creating a non-removable structure. These cabinet lights are sold as complete, pre-assembled units, suitable only for custom-sized cabinets and not for cabinets of varying widths. Furthermore, repairing or replacing part of the light source often requires a cumbersome disassembly and reassembly process. Utility Model Content
