Abstract: An LED bulb contains: a first shell, a second shell, a heat dissipating element fixed between the first shell and the second shell. The dissipating element includes a first substrate and a second substrate which correspond to the first shell and the second shell, wherein the first substrate includes at least one first LED lighting element, and the second substrate includes at least one second LED lighting element, such that lights illuminate out of the second shell and the first shell via a plurality of heat dissipation fins, thus having omnidirectional illumination. The at least one first LED lighting element of the first substrate illuminates the lights at 180 degrees. Preferably, the second shell is a sphere-shaped shell, a semi-arcuate shell or a flat shell to satisfy different using requirements.
