Zusammenfassung:Disclosed are an LED lamp structure driven by double current and a double current driving method thereof. The LED lamp structure driven by double current includes a COB package, a temperature sensor, and a controller. The COB package is provided therein with a blue LED chipset to be driven by a first current and a red LED chipset to be driven by a second current. The temperature sensor detects the working temperature of the red LED chipset, and the controller performs dynamic adjustment on the second current according to the working temperature so as to stabilize the color temperature of the LED lamp structure. Thus, as soon as the LED lamp structure is activated, its color temperature will be stabilized to ensure user comfort, which may otherwise be disturbed by variation of the color temperature.
