Abstract
A light emitting device of an embodiment includes at least one light source; a wavelength conversion unit for converting the wavelength of excitation light so as to emit the excitation light having the converted wavelength as conversion light; a light transfer unit disposed on a light path between the at least one light source and the wavelength conversion unit for transferring the excitation light to the wavelength conversion unit; and a light-path controller moving at least a part of the light transfer unit so as to adjust at least one from among the direction and intensity of excitation light which enters the wavelength conversion unit.
