Light string with a non-extinguishing function and an independent LED blinking function

Abstract

A light string with a non-extinguishing function and an independent LED blinking function includes an LED light string having a plurality of LED bidirectional lamp groups and a plurality of LED independent blinking lamp groups connected in series, and a switchable-polarity power supply connected to the LED light string for providing a pair of DC voltages with switchable polarity to the LED light string. The LED bidirectional lamp group includes a plurality of LED bidirectional lamps connected in parallel, and the LED independent blinking lamp group includes a blinking control circuit and a plurality of LED bidirectional lamps connected in parallel. The plurality of LED bidirectional lamps may be a plurality of LED two-color bidirectional lamps or LED mono-color bidirectional lamps; and the blinking control circuit controls the plurality of LED bidirectional lamps to blink independently and to cyclically vary the brightness of the plurality of LED bidirectional lamps.
