Abstract
A light emitting device including a light emitter to emit white lights having different color temperatures, and a base including a circuitry for supplying power to the light emitter, in which the light emitter includes light emitting units each including a light emitting diode to emit light having different peak wavelengths, the white lights are defined by light emitted from each of the light emitting units or a combination of light emitted from each of the light emitting units, white lights include a first white light having a first x-coordinate value equal to or greater than an x-coordinate of the color temperature 10000K, a second white light having a second x-coordinate value equal to or greater than an x-coordinate of the color temperature 1800K, and a third white light has a third x-coordinate value between the x-coordinates of the color temperature 1800K and 10000K.
