Zusammenfassung:	The utility model provides a high-efficiency LED driving module for illumination. The high-efficiency LED driving module comprises an MCU control unit, a CAN communication interface unit, a switch synchronous control unit, an energy conversion unit and an illumination LED array, the CAN communication interface unit is used for controlling on-off and brightness adjustment control information of a control panel and sending the control information to the MCU control unit. The switch synchronous control unit is used for receiving the PWM control information from the MCU control unit and driving a switch element of the energy conversion unit according to the duty ratio of the PWM control information; the energy conversion unit is driven by the switch synchronous control unit to carry out boost/buck voltage conversion on the output of the storage battery and provide power supply drive for the illumination LED array; and the brightness is adjusted under the control of the driving source. The brightness of the LED dr
