An electronic power supply device is provided for light-emitting diodes (LEDs), which employs electronic control to maintain the LEDs within the rated ranges of current, voltage and temperature and provides the LEDs with extremely stable current, voltage and temperature. Meanwhile, the power supply device is effective in confining the LEDs within the rated ranges of voltage, current, and temperature so that the excellent electronics protection and design of logic device realized by the power supply device effectively overcomes aging/deterioration of LEDs caused by exceeding voltage and current and burning out due to exceeding temperature and also effectively pushes the rated current and voltage of a (low-power) LED module toward the maximum values to provide the greatest luminous efficiency for upgrading the applications of the LEDs to the primary grade of lighting.
