The radiator 307 is arranged in the lamp post base 301, the mounting seat 306 is arranged at the top of the radiator 307, the thermally conductive column 305 is installed at the top of the mounting seat 306, the LED lamp substrate 304 is installed on the outer wall of the thermally conductive column 305, the LED high-brightness lamp beads 303 are installed on the LED lamp substrate 304, and the lamp post cover 302 is installed at the top of the lamp post base 301.

In the embodiment of the utility model, the lamp post base 301 is generally in the shape of a hollow column, and the bottom outer wall of the lamp post base 301 is provided with two circles of annular mounting protrusions. At the same time, a circular ventilation hole that passes through the inside and outside is opened on the middle outer wall of the lamp post base 301. The LED lamp main control circuit board is installed at the bottom of the inner cavity of the lamp post base 301. The circular ventilation hole enables the radiator 307 to dissipate heat from the thermal conductive column 305 more efficiently.

In the embodiment of the utility model, the radiator 307 is installed in the middle of the inner cavity of the lamp post base 301, and a mounting seat 306 is arranged at the top of the radiator 307. The contact surface between the radiator 307 and the mounting seat 306 is coated with thermal conductive silicone grease, so that the heat transferred from the thermal conductive column 305 to the mounting seat 306 can be transferred to the radiator 307 more quickly.

In the embodiment of the utility model, the heat-conducting column 305 is a copper column, which is fixedly installed on the top of the mounting seat 306, and a plurality of rectangular long grooves are opened in the vertical direction on the outer wall of the heat-conducting column 305 for installing the LED lamp substrate 304. The copper heat-conducting column 305 has good thermal conductivity and can efficiently export the heat of the LED lamp substrate 304.

In the embodiment of the utility model, a power supply connector is provided at the top of the mounting seat 306 at the position of the rectangular long groove opened by the heat conducting column 305, and the mounting seat 306, the heat sink 307 and the LED lamp main control circuit board are connected in sequence through power supply lines to ensure the normal operation of the LED high-brightness lamp bead 303.

In the embodiment of the utility model, the LED lamp substrate 304 adopts an aluminum substrate to install the LED high-brightness lamp beads 303. The LED lamp substrate 304 is installed in the rectangular long groove opened by the heat-conducting column 305, and is connected to the power supply connector set at the top of the mounting seat 306.

Working principle: After the power is turned on, the LED high-brightness lamp bead 303 lights up. During the lighting process, the heat generated by the LED lamp substrate 304 is first transferred to the heat-conducting column 305, and then the heat-conducting column 305 further transfers the heat to the radiator 307 through the mounting base 306. Through the work of the radiator 307, the purpose of dissipating heat from the lamp column 3 is finally achieved.
