Abstract

The utility model discloses an LED spot light, which comprises a light cup, one or more high-power LED lights arranged in the light cup, and a conductor connected with the LED lights. The LED lights are fixed to one face of a cooling fin. The cooling fin is provided with a plurality of connection holes. The inner bottom of the light cup is a plane, and is provided with screw holes which correspond to the connection holes on a one-to-one basis. Screws pass through the connection holes to tightly connect the cooling fin to the screw holes arranged on the inner bottom of the light cup. As the structure is adopted, the LED spot light provided by the utility model can effectively avoid poor cooling effect as a result of too small contact surface between the cooling fin and the light cup and defective tightness of the connection of the cooling fin and the light cup. In this way, the service life of the LED spot light is significantly improved, and the use cost of the product is saved indirectly.
