A light emitting package is disclosed that can generate a white light while controlling Red, Green and Blue light emitting diodes ('LEDs') simultaneously. In the light emitting package, a plurality of LEDs are connected in series to one another. The plurality of LEDs are responsive to one driving voltage. Currents flowing through the plurality of LEDs are controlled by a current adjuster. Consequently, the plurality of LEDs are driven by the currents different from one another in amount.
