[0002] LED lighting fixtures refer to devices that can transmit, distribute, and change the light distribution of LED light sources. They include all components and parts required to fix and protect the LED light source, as well as wiring accessories necessary for power connection. Through semiconductor technology innovation, LED lighting fixtures have become the mainstream choice for modern lighting. Their high efficiency, energy saving, long life, and environmental protection characteristics have not only reduced energy consumption but also promoted the intelligent and green development of the lighting industry. However, when using existing LED lights, replacing the driver power supply requires disassembling and reassembling each component of the light fixture step by step, which is complicated, time-consuming, and labor-intensive. Users may also damage the light fixture if they fail to disconnect the power or make wiring errors when replacing the driver power supply themselves. Therefore, we propose an LED light fixture that facilitates driver power supply replacement. Utility Model Content

The power supply housing has a heat dissipation fin fixed inside, a locking block at the bottom, and conductive posts installed at the four corners inside. The top of the power supply housing is provided with a locking groove, and the bottom of the inside of the power supply housing is symmetrically provided with a power connection hole. The power supply body is installed inside the power supply housing. Among them, the heat dissipation fin is trapezoidal, and a heat dissipation plate is connected to the bottom of the heat dissipation fin; The engaging slot and engaging block work together to engage and connect power housing one and power housing two.
