An LED power circuit (1) for converting AC power into DC power to drive at least one LED to output light. The LED power circuit (1) includes an input unit (12), a current suppression unit (14), a power adjustment unit (15), a rectifier module (16) and an output unit (20). The input unit (12) receives the AC power. The current suppression unit (14) is coupled to the input unit (12). The current suppression unit (14) suppresses a current pulse and correspondingly outputs the AC power. The power adjustment unit (15) is coupled to the current suppression unit (14) to control and adjust the current and/or the power of the AC power. The rectifier module (16) is coupled to the power adjustment unit (15) to convert the AC power into DC power. The output unit (20) is coupled to the rectifier module (16) and at least one LED. The output unit (20) outputs the DC power to the at least one LED. |
