The invention relates to a flyback-type quick-start LED (Light-Emitting Diode) drive circuit structure, belonging to the technical field of circuit structures. The circuit structure comprises a voltage input module, a load output module, a transformer, a feedback control circuit module and a quick-start control circuit module, wherein an output end of the quick-start control unit is connected with a control end of a switch; the switch is connected between a source electrode of an external power tube and an output end VCC (Collector Supply Voltage) of a power supply unit and is connected with one end of the source electrode of the external power tube and an output end of the feedback control circuit module. According to the invention, the source drive of the quick-start control unit is realized, in addition, power is supplied to a control circuit from the source electrode through the switch, starting resistance is reduced, meanwhile, the quiescent current of a drive module is reduced, and the power consumption is reduced; and quick start within 200ms is realized, the drive efficiency is improved, meanwhile, the actual area and the cost of the circuit structure are reduced, and a wider application range is achieved.
