The present invention discloses a multi-modulation mode LED driving circuit, which controls an inverter to perform energy conversion to drive at least one LED. The driving circuit of the present invention is modulated by a timing control signal containing an on time and a standby time. In the present invention, a varying-amplitude modulation energy is added to the standby time. In the present invention, the start and end of the on time respectively have a gradually-ascending interval and a gradually-descending interval, and/or the start and end of the standby time respectively have a gradually-descending interval and a gradually-ascending interval. In the present invention, two or more different cycles are mixed to generate high-reliability and wide-dynamical range modulation modes, which can make an energy conversion unit and a rear-end LED group operate in reliable ranges of some performance characteristics.
