The invention discloses a non-flicker energy-saving environment-friendly LED lamp strip. The lamp strip comprises a rectifier circuit, a filter circuit and an LED circuit. The filter circuit comprises a resistor R1, a resistor R2, a capacitor C1, a capacitor C2, a capacitor C3 and a capacitor C4. The LED lamp strip can be used for filtering through the RC filter circuit, and a power supply outputs smooth direct current through multi-stage filtering so that it can be guaranteed that an LED works in a relatively stable voltage state, and emitted light is not stroboscopic. Besides, the lamp strip is effectively protected against influences of voltage surge, operation is stable and reliable, and the service life of the lamp strip is greatly prolonged. Besides, the LED lamp strip is not stroboscopic when photographing is carried out under the light environment where the LED lamp strip is used.
