    • Disclosed is an alternating current dimming drive circuit for an LED, comprising a rectification unit and N stages of LED direct current drive circuits. In the ith stage of LED direct current drive circuit, a first end of the ith voltage sampling unit and an input end of the ith LED light source module directly or indirectly receive the output voltage of the rectification unit; a voltage division end of the ith voltage sampling unit is connected to a second input end of the ith switch unit; and a first input end of the ith switch unit is connected to an output end of the ith LED light source module, and an output end of the ith switch unit, a second end of the ith voltage sampling unit and a second output end of the rectification unit are grounded. When the ith switch unit is switched on, the first to the ith LED light source modules emit light. When the ith switch unit is switched off, if i is less than N, the first to the (i+1)th LED light source modules emit light, and if i is equal to N, the first to the Nth LED light source modules stop emitting light. The present invention realizes an alternating current directly-driven LED light source module and will not flicker in the case of alternating current voltage fluctuation.
