Claim:
1. An LED actuating device, comprising an LED actuating module, said LED actuating module comprising a micro-programmed control unit (MCU), an actuator, a VF-value detection module for detecting the forward operating voltage value, a PN-junction temperature acquisition module and an LED lamp unit, wherein the MCU determines the current value matched with the LED lamp unit according to the forward operating voltage value detected by the forward operating voltage value detection module and the temperature value detected by the PN-junction temperature acquisition module and then according to the current value, determines the width of the PWM pulse output to the actuator so as to actuate the LED lamp unit to operate at the matched value by the actuator; wherein the MCU comprises a performance data proofreading base of the forward operating voltage value; the MCU searches the current value corresponding to the detected forward operating voltage value in the performance data proofreading base of the forward operating voltage value and the current value is matched with the LED lamp unit; wherein when no current value corresponding to the detected forward operating voltage value in the performance data proofreading base is searched, the MCU calculates the average value of the current values corresponding to the two forward operating voltage values adjacent to the detected forward operating voltage value in the performance data proofreading base as the current value corresponding to the detected forward operating voltage value, wherein the detected forward operating voltage value is between the two adjacent forward operating voltage values.
