Referring to fig. 1, the technical solution provided by the present invention is:

From the above description, the beneficial effects of the present invention are:

The working principle of the LED street lamp shade with high heat dissipation performance is as follows:

during the installation, install lamp panel and LED lamp in the casing, then will descend the lamp shade to install in the casing bottom, when LED lamp work produced the heat, the heat transmits to the lamp shade in through the heat dissipation fin, then carries out quick conversion through the subassembly of taking a breath with the inside heat of lamp shade again, thereby dispel the heat to last lamp shade fast, make the inside temperature reduction of lamp shade and then can continue to accomplish the heat transfer through the heat dissipation fin, thereby make the inside heat reduction of casing, improve LED's life.

From the above description, it can be known that the hot air in the upper lamp cover can be pumped into the refrigerator through the air pump, and is discharged into the upper lamp cover again after being refrigerated by the refrigerator, so that the heat exchange is completed, and the heat exchange is rapidly performed in the upper lamp cover.

From the above description, it can be known that the lamp panel can keep a certain distance from the top of the inner cavity of the housing when being installed through the mutual matching of the threaded column, the first nut and the second nut, so that the heat of the lamp panel can be rapidly dissipated.

Furthermore, the threaded column is made of copper.

As can be known from the above description, the threaded column is made of copper, so that the copper column has a good heat conduction effect and can facilitate heat transfer.

As is apparent from the above description, the heat dissipation effect of the case can be further improved by providing two or more heat dissipation fins on the outer surface of the case.

Referring to fig. 1 and fig. 2, a first embodiment of the present invention is:

referring to fig. 1, a high heat dissipation LED street lamp cover includes an upper lamp cover 1, a housing 2 and a lower lamp cover 3, the upper lampshade 1 is fixedly arranged on the outer surface of the shell 2, the lower lampshade 3 is covered at the opening of the shell 2 and closes the opening, a lamp panel 6 and an LED lamp 5 are arranged in the inner cavity of the shell 2, the LED lamp 5 is arranged on one side surface of the lamp panel 6 close to the lower lampshade 3, a radiating fin plate 4 is embedded on one side surface of the shell 2 close to the upper lampshade 1, an air exchange component 7 is arranged on the outer surface of the upper lampshade 1, an air inlet pipe 8 and an air outlet pipe 9 are respectively communicated with two opposite sides of the air exchange component 7, one end of the air inlet pipe 8 extends to the inner cavity of the upper lampshade 1, an air inlet at one end of the air inlet pipe 8 faces the radiating fin plate 4, one end of the air outlet pipe 9 extends to the inner cavity of the upper lampshade 1, and the air outlet at one end of the air outlet pipe 9 faces the radiating fin plate 4.

The heat dissipation fin plate 4 is embedded in the center of one side face, close to the upper lampshade 1, of the shell 2.
