Abstract
An LED actuating device comprises an LED actuating module, the LED actuating module comprises a micro-programmed control unit (MCU), a VF-value detection module, an actuator and an LED lamp unit; the MCU receives the VF value detected by the VF-value detection module; when the VF value is greater than or equal to a first boundary value, the LED lamp unit is actuated to operate in the constant current area at the first constant actuating current by the actuator; when the VF value is less than the first boundary value, the LED lamp unit is actuated to operate in the regulation area at the continuous step-down actuating current by the actuator until the VF is equal to the second boundary value, and the second boundary value is less than the first boundary value.
