detailed description

Referring to Fig. 1 to Fig. 4, Fig. 1 to Fig. 4 are structural schematic diagrams of the first specific embodiment of the present utility model, as shown in the figure, a driving split type outdoor lamp includes a lamp body, and the lamp body includes a lamp body Housing 1, LED light source assembly and power supply 3, the LED light source assembly is arranged in the lamp housing 1, and a power supply housing 2 is placed outside the side or rear end of the lamp housing 1, preferably, in this embodiment, the The power supply shell 2 is installed on the rear end of the lamp shell 1 through screws, and a bottom shell can also be configured at the bottom of the power supply shell 2, so as to seal the power supply without a shell. The power supply 3 is arranged in the power supply shell 2. The utility model adopts The structure of the external power supply simplifies the internal structure of the lamp housing 1, prevents the LED chipset and the power supply from being located in the same cavity, facilitates the diffusion of heat, reduces the pressure of heat dissipation, ensures the effect of heat dissipation, and simplifies the process of die-casting or The mold structure during the manufacture of the dosage form simplifies the production and assembly process.

Preferably, both the power supply housing 2 and the lamp housing 1 are provided with waterproof connectors 31, and the power supply 3 is connected to the LED light source assembly through wires 32 passing through the waterproof connectors 31 to ensure waterproof effect.

Preferably, the power supply housing 2 and the lamp housing 1 are made of thermally conductive materials such as copper and aluminum, and a number of cooling fins are arranged on the outer walls of the power supply housing 2 and the lamp housing 1 to improve the effect of heat dissipation.
