The present invention provides a self ballasted LED lamp, which includes a lamp head, a substrate, a driving power supply, a spherical glass shell, and a light emitting module and a heat dissipation module located within the spherical glass shell. The heat dissipation module includes a heat sink base with a cylindrical internal space and a heat sink core column, and the light emitting module is arranged on the substrate, and the substrate is located at the top of the heat dissipation core column. The LED lamp of the present invention has a structure similar to that of a traditional incandescent lamp bulb, with the spherical glass shell accounting for the largest proportion and the radiator accounting for the smallest proportion. Most of it is hidden inside the spherical glass shell, with simple structure, low cost, and large lighting angle
