The utility model discloses a light-emitting diode heat radiation structure and a light-emitting diode bulb. The LED heat radiation structure comprises a heat-conducting body and a heat radiation shell, wherein the heat-conducting body is made of metal and has a heat-conducting effect, and the heat radiation shell is sleeved on the outer wall of the heat-conducting body and plays the role of heat radiation on the heat-conducting body; and the inner wall of the heat radiation shell is tightly contacted with the outer wall of the heat-conducting body. With the adoption of the structure, the hot convection effect is greatly improved through a ventilation design of a through hole; the heat radiation capability is enhanced; and the service life of the LED bulb is prolonged.
