Abstract
A mother bulb controller includes a first light emitting body, a first pin, a second pin, and a control board. The control board includes a first resistor, a capacitor, and an IC controller which includes a power supply end, a ground terminal, an input end, and an output end. One end of the capacitor is electrically connected to the power supply end and another end of the capacitor is electrically connected to the ground terminal. The input end is electrically connected to one end of the first light emitting body, and another end of the first light emitting body is electrically connected to the first pin. The output end is electrically connected to the second pin. The control board is configured to turn on the first light emitting body and drive an external load to work.
