Abstract
A light-emitting device package includes a substrate; a light-emitting device provided on the substrate and configured to be driven by an AC power supply; and a capacitor connected in series with the light-emitting device, where a capacitance of the capacitor varies so that a current flowing through the light-emitting device and flowing through the capacitor is maintained at a constant value according to a variation in temperatures of the light-emitting device and the capacitor.
