Abstract
The invention discloses a cooling structure of an LED spotlight. The cooling structure comprises a shell, a light body, clamping hands and a junction box. The lamp body is arranged in the shell, a fixing and holding support is arranged at the top of the shell, the junction box is arranged on the fixing and holding support and is electrically connected with the light body, the clamping hands are arranged on two sides of the shell, and a substrate is arranged inside the light body. An LED module, a lens module and glass are respectively arranged on the lower surface of the substrate, and a cooling fin is connected on the upper surface of the substrate. An opening is arranged on one side at the top of the shell, a plurality of cooling holes are reserved at the top of the shell, and the opening and the cooling holes form convection channels. Heat generated by the cooling fin is effectively transmitted to the outside of a device through the convection channels, and cooling effect is good.
