An LED current control circuit according to an embodiment of the present invention includes: a dimmer which receives power supplied from an AC source; a stabilizer which provides a driving voltage by using a voltage outputted from the dimmer; a driving control unit which senses the voltage outputted from the stabilizer and generates a current reference value of an LED driver; and the LED driver which generates a DC constant current by receiving the driving voltage controlled by the driving control unit. [Reference numerals] (410) Ballast stabilizer detecting unit; (420) Dimming level determining unit; (430) LED current reference value generating unit |
