  • Publication number: 20240147592
    Abstract: The present disclosure relates to a light emitting diode (LED) driving device that may expand a usable range of LED current and battery voltage by reducing heat generation of an integrated circuit, and an LED lighting device including the same, which may include a current controller that constantly controls an LED current flowing through an LED string and an IC heat dissipation part connected to a node between the LED string and the current controller to dissipate IC heat of the current controller, wherein when a battery voltage supplied to the LED string increases, the IC heat dissipation part reduces a first LED current flowing from the LED string to the current controller and simultaneously increases a second LED current flowing from the LED string to the current controller via the IC heat dissipation part, thereby reducing the IC heat generation of the current controller.
