<p>The present invention discloses an LED lighting device decreasing current amount variation for changes in temperature. The LED lighting device of the present invention is connected to rectifying voltage and comprises an LED light emitting block including at least one LED module and having a tap formed at the cathode terminal of the at least one LED module; a variation reference voltage generating block generating variation reference voltage; and a switching block driven to compose a closed circuit including the at least one LED module formed at the tap by being connected to the tap and having the current amount flowing in the closed circuit is controlled by the variation reference voltage. The variation reference voltage is controlled to decrease the variation the current amount, which is flowing in the closed circuit, according to temperature changes. According to the LED lighting device of the present invention, the variation of the amount of the flowing current according to the temperature changes is decreased.
