WIPO Patent Application WO/2018/041125
Kind Code:
A1
Abstract:
An LED lamp base (1) and an LED bulb. The LED lamp base (1) comprises a housing (4), a printed circuit board (5), and a common mode coil (6). The common mode coil (6) is disposed on the PCB (5). A first groove (41) and a second groove (42) are configured in an inner wall of the housing (4). A first end of the PCB (5) is slid in the first groove (41), and a second end of the PCB (5) is slid in the second groove (42). The thickness of the first groove (41) and thethickness of the second groove (42) are matched with the thickness of the PCB (5). By configuring the common mode coil (6) in the LED lamp base (1), the impact of a change in the inductance coefficient may be avoided, thus ensuring an ability of the common mode coil (6) in reducing the electromagnetic interference.
