A Light Emitting Diode (LED) bulb includes a circuit board assembly, a base, a first LED light source module and a second LED light source module disposed on two opposite surfaces of the circuit board assembly, and a shell. The base includes a reflective surface. After passing through the shell, a first light beam emitted by the first LED light source module and a direct light beam emitted by the second LED light source module respectively form a first light distribution pattern and a third light distribution pattern. After being reflected by the reflective surface and emitted from the shell, a reflected light beam emitted by the second LED light source module forms a second light distribution pattern. The first light distribution pattern, the second light distribution pattern, and the third light distribution pattern superpose to each other to form an omni-directional light distribution pattern.
