Generally, an ordinary LED lamp bead is composed of positive and negative pins, an LED light emitting chip and a packaging shell. To meet the market demand for dynamic light efficiency of LED lamp beads, LED lamp beads with flickering function have also emerged. Compared with ordinary LED lamp beads, an integrated circuit (IC) is added in the packaging shell to control the LED light emitting chip, realizing the flickering function of the LED lamp bead. However, the traditional flickering LED lamp bead is limited to direct current power supply mode and is difficult to adapt to alternating current grid environment.
