Bidirectional illuminated LED bead triggered by power line pulse signals

A bidirectional illuminated LED bead triggered by power line pulse signals, the illuminated LED bead comprising:

• a first illumination module triggered by the power line pulse signals and a reverse light emitting module, wherein said first illumination module triggered by the power line pulse signals and said reverse light emitting module are connected in parallel with each other between a first power line port and a second power line port of the LED bead;
• said first illumination module triggered by the power line pulse signals comprises an LED color light group and an LED driver that drives said LED color light group based on the power line pulse signals loaded on power line ports;
• wherein when a voltage level at said first power line port is higher than a voltage level at said second power line port, said LED driver drives said LED color light group based on said power line pulse signals loaded on the power line ports;
• and when the voltage level at said first power line port is lower than the voltage level at said second power line port, said reverse light emitting module operates;
• wherein said LED driver comprises a reverse current blocking module and an operation module triggered by the power line pulse signals;
• when the voltage level at said first power line port is higher than the voltage level at said second power line port, said first illumination module triggered by the power line pulse signals drives said LED color light group based on said power line pulse signals loaded on said first power line port, or said second power line port, or a combination of both the first and the second ports;
• said reverse current blocking module and said operation module triggered by the power line pulse signals are integrated into a single integrated circuit;
• and
• said first illumination module triggered by the power line pulse signals and said reverse light emitting module are sealed by a translucent gel;
• and said first power line port and said second power line port are led out from said translucent gel by conductors.
