[0002] An LED downlight is an indoor general lighting fixture composed of an array of LED light sources supplemented by a dedicated structure. One problem with LEDs themselves is that the light efficiency of the fixture is greatly affected by the chip junction temperature. A higher chip junction temperature will lead to a decrease in light efficiency and affect the service life of the LED downlight. Therefore, solving the heat dissipation problem of the LED downlight is crucial for improving the performance of the LED downlight. However, the existing radiator has a limited surface area, resulting in poor heat dissipation effect. Content of the Utility Model
