ABSTRACT:
A limited flicker decorative light-emitting diode (LED) string includes a power plug adapted to connect to an alternating current (AC) power source and supply AC power to the LED string, a first pair of LEDs and a second pair of LEDs, a plurality of LEDs electrically connected in series to form an LED series, and a plurality of rectifying diodes. The plurality of rectifying diodes provides full-wave rectification of the AC power to the LED series and half-wave rectification of the AC power to the first and second pair of LEDs.
