The utility model relates to the technical field of LED lamps, in particular to a heat dissipation structure of an LED lamp, heat dissipation through holes are formed in the two sides of a shell in a penetrating mode, installation grooves are formed in the positions, located at the two ends of the heat dissipation through holes, of the two sides of the shell, and sealing assemblies are arranged in the installation grooves. The sealing assembly comprises two air cylinders located in the mounting groove, the telescopic ends of the two air cylinders are jointly provided with a sealing plate, the sealing plate penetrates through the mounting groove and extends to the heat dissipation through holes, and a sealing gasket is arranged on one side of the sealing plate in a tightly attached mode. In the using process of the whole heat dissipation structure, the sealing plate is driven by the air cylinder to move towards the inner side of the mounting groove, the heat dissipation through holes are opened, heat generated
