[0030] LED lighting fixtures are energy-saving and healthy lighting fixtures. They refer to devices that can transmit, distribute and change the light distribution of LED light sources. In addition to the LED light source, they include all parts and components required to fix and protect the LED light source, as well as the circuit accessories necessary to connect to the power supply.

[0031] At present, the power supply of LED lamps is all built-in, that is, the power supply is placed inside the lamp. On the one hand, lamps with built-in power supply will generate heat when working. The heat generated by the power supply and the light source will be superimposed on each other, causing serious aging of the lamp and affecting the life of the lamp. On the other hand, the aging of the power supply of the lamp with built-in power supply will cause the entire lamp to fail. Disassembly and replacement require opening the power supply cavity of the street lamp to replace it, which is inconvenient to replace and has high maintenance costs.

[0032] In an embodiment of the present application, the power supply component 2 and the lamp body 1 are connected and assembled into an integral body through the connecting component 3. The power supply is external and can be quickly disassembled and installed together with the lamp as a whole, so that the power supply can be replaced at any time, extending the life of the lamp and reducing maintenance costs.
