Abstract
The present disclosure provides an LED lamp base and an LED bulb. The LED lamp base comprises a housing, a printed circuit board, and a common mode coil. The common mode coil is disposed on the PCB. A first groove and a second groove are configured in an inner wall of the housing. A first end of the PCB is slid in the first groove, and a second end of the PCB is slid in the second groove. A thickness of the first groove and a thickness of the second groove are matched with a thickness of the PCB. By configuring the common mode coil in the LED lamp base, the impact of a change in the inductance coefficient may be avoided, thus ensuring an ability of the common mode coil in reducing the electromagnetic interference.
