The invention relates to a gas heat convection heat dissipating structure of an LED bulb. The gas heat convection heat dissipating structure of the LED bulb comprises a radiator, an insulating connecting sleeve, a shade preventing sleeve, a lampshade and a lampshade top cover. A cavity and cooling fins are arranged in the radiator and a plurality of ventilated channels are formed in the radiator. An LED lamp panel is installed on the outer wall of a cavity body of the radiator. Gaps for cavity ventilation are arranged between the radiator and the insulating connecting sleeve, between the radiator and the lampshade, between the lampshade and the lampshade top cover and between the lampshade top cover and the shadow preventing sleeve. The gas heat convection heat dissipating structure of the LED bulb has the advantages that the structure of inner air ducts is added to a heat dissipating device of a product, so that air flow with the specific flow direction is generated inside the LED bulb, and the process of he
