<p>The invention relates to the related technical field of light emitting diodes (LEDs), in particular to a self-adaptive drive circuit and an LED lamp with the same. The LED lamp comprises a plurality of series LED lamp strings, and each LED lamp string comprises at least one series LED lamp bead; and the self-adaptive drive circuit comprises a rectifying unit, a current limiting unit, a voltage detection and connectivity control unit and at least one controllable switch unit. According to the self-adaptive drive circuit and the LED lamp with the same, the LEDs work normally in an extremely simple mode, a complex constant current drive circuit and an electrolytic capacitor with life limitation are eliminated, meanwhile, stroboflash is eliminated, the power factor is improved, harmonic distortion is reduced, electromagnetic interference is eliminated, and the cost is reduced.</p> |
