Abstract: An actuating device comprises an LED actuating module. Said LED actuating module comprises a micro-programmed control unit (MCU), an actuator, a VF-value detection module, a PN-junction temperature acquisition module and an LED lamp unit. The MCU determines the current value matched with the LED lamp unit based on the VF value detected by the VF-value detection module and the temperature value detected by the PN-junction temperature acquisition module, and then determines the width of the PWM pulse output to the actuator according to the current value, and the actuator actuates an LED to operate at the matched current value.

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.
