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.
